In some vehicles, the belt tension is established by an adjustable bracket on an accessory such as the alternator. Homemade Wind Generator Made With A GM 1-Wire Alternator. The two pulleys were of equal size so the speed on the intermediate shaft would be exactly the same as the speed of the motor on the right side. So, what I ended up doing was to drive the motor on the right through an intermediate shaft which had a multi step pulley on it. To learn more, see our tips on writing great answers. In the second answer, in the top view, is that 2 plates with the roller in the middle? This meter provides an easy to read indication of the generator output voltage. This device allows you to monitor and set the engine rpm such that it rotates at the specified RPM required by the generator head. Why would a HR still ask when I can start work though I have already stated in my resume? This is an RPM (revolutions per minute) meter or tachometer. I'm not going to discuss this much as it gets a bit complicated, but there is an example of an intermediate shaft being used below. In more detail: In this application the same engine can direct drive a generator head while belt driving an alternator for DC charging purposes. This allows for direct driving the generator head by using a shaft coupler. 95 So, if you are using an 8 HP motor with this AC generator head and can insure you never will use more than say 2500W of AC power, then there is enough horse power left to be able to belt drive a 12 volt alternator running at say 40 amps (14.4 volts x 40 amps = 576 Watts) with some head room when belt driven off the same shaft. First road bike: mech disc brakes vs dual pivot sidepull brakes? How should I go about this? The alternator, power steering pump, water pump, and air-conditioning compressor may all be connected to this serpentine belt. If you still don't believe any of the above will be able to work, my next idea is a lot more wilder and a bit harder to implement. One final note: If you are using an alternator that requires an external switch, you will need to turn off the switch prior to attempting to start the generator. theYear=theYear+1900 A Math Riddle: But the math does not add up. Add this bracket — makes it easy! To connect the output shaft of a motor to a generator head input shaft (or anything else), a special shaft coupler is required. They are very specialized and a bit expensive. Or if you're seeing this post on Facebook then click on this link below÷ ⬇️ ⬇️ ⬇️ Both the motor and the generator head rotate in the correct directions. I'm getting such a poor charge and don't really know what to do. Measure the engine RPM with an inductive Tachometer, and also know when to change the oil! You may need to get creative to make something happen, but with a little bit of ingenuity can be done with good results. Engine RPM / Generator RPM = Generator pulley size / Engine Pulley size. What does this sideways triangular marking mean? The Belt runs parallel to a wooden 'wall', with a clearance of about 4 inches. So, knowing the generator needs to rotate at 3600 RPM, next define what speed the engine needs to run at. Mounting for it is not really mounting, but rather, Visual design changes to the review queues, Opt-in alpha test for a new Stacks editor, How can I remove Factory Air Conditioning from a 1965 Mopar Big Block.

To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Loosen the nuts, pushing the alternator if necessary to create slack on the belt and remove it. So, what ever size pulley is selected for the generator, the engine pulley size must be 2 times that size. A boater passing through who's good with engines said the bolts don't really have enough room to fit anything to them, and welding's the only real way around it. Alternator belts Left, the cap nut for adjusting the Poly V blt from the front. Let me know what you think. if (theYear < 1900) Voltages out side of those ranges are indicated in red. So, place the shafts facing each other and guess what? If you are unable to define a pair of pulleys that are standard, available and give you the exact ratio, then there are three choices: We put together the table below to help you find pulley sizes that are considered standard in the industry. A new alternator for these cars is worth about $200 plus fitting if done by your local garage, but often it is worn brushes that stop the alternator from charging the car battery and these are easy to replace. In either of these cases, the alternator may be needed to moved or rotated to achieve your goal. Rocky Mountain OilsFAST & FREE SHIPPING in the U.S. TheEpicenter.comEpicenter Supplies LLC Select a coupler half that is the correct size to fit the motor shaft (or driving shaft size), then select a coupler half that is the correct size for the generator head (or Driven shaft size). This slot would probably need to be fairly long to allow for decent movement of the rod and bearing. How to understand "cupping backsides is taken as seriously as cooking books"? All you need is a socket set and spanners plus a brush and regulator replacement kit for your model of alternator. TheEpicenter.com | Epicenter Supplies LLC. OTHER PRODUCT TIPS & RECOMMENDATIONS | #EpicenterJanet, Mountain House Pouch Status Update - September 17, 2020, Mountain House Military LRP/MCWs and New Pro-Paks, 2020 UPDATE: Mountain House Freeze Dried Foods Product Line. Since belts of different styles ride higher or lower in the groove of the pulley, the effective diameter of the pulley can change if another type of belt is used, but the effect is seen on both pulleys so the ratio of pulley size is still applicable for most applications. Typical Gas engines rate their horse power at 3600 RPM. About the "wall of word award" ... would you expect any less from me? However, the motor on the right had a very small pulley which was frozen on the shaft and there was no way to remove it. For a DIY task, you will simply require a socket wrench set. The unit shown also keeps a running total of engine usage and display the number of hours and minutes the engine has operated. Knowing that I needed the engine to run at 3450 rpm and the generator to run at 1725 rpm, then... 3450 RPM / 1725 RPM = 2. Please accept our apologies for the inconvenience. Then say I've got a 2" pulley that fits the engine side, that means that the generator side needs to be twice as large, or 4". A better case could be made for building a multipurpose power generation system because it is not something that you can currently buy. However, the generator head we use is designed to handle the job. Since I had a 3" pulley already for the engine, I needed to determine the pulley size that would be correct or the generator shaft. I've got a diesel engine in my boat, but the previous owner had somehow snapped the alternator bracket, and fitted it fixed to the boat rather than the engine. In this configuration, the generator bearings see a high side load and not all generator heads are built with the required bearings to handle this side load. ... One, the stock Delco alternator stator wiring needs to be replaced with a stator that has more turns of smaller gauge wire and high powered neodymium magnets replace the standard magnets to give more power output. The AC generator head is direct coupled to the Tecumseh 8 HP motor, and has a belt driven 12 volt alternator mounted to our Horizontal generator bracket which is attached to the motor. Repeat until belt snaps and fit another belt. The project could stop here if DC is not required*. The motor on the left is a one hoarse power motor which turns at 3,450 rpm when powered with 120 VAC and the motor to the right is an induction motor that runs normally at 1725 rpm. If your belt is too tight, you could shear the bolts of the pulleys, or the belt itself might break off while you are driving. now = new Date In the example shown, I was attempting to convert an induction motor into a generator (that's something that is outlined in the booklet "alternator secrets"). In this application you might need to charge of bank of batteries as an example at the same time as having some AC power available. I mention this only for academic reasons (so some smart ass out there doesn't beat me to the punch) because the other choices below are simpler. Attaching to two or more brace points (two braces connected or not) would be better. Edge belt sander mode. I'll see if I can catch someone to take a look as the engine bolts to see if they will cause a leakage if removed. In two of your pictures, I have circled some areas which may be points you can use as mount points for what I'm going to suggest. To develop the full rated output power from this head, the engine should really be a 10 HP model like the HM100, or better yet an 11 HP model for a bit more headroom. We will discuss how to build your own generator that looks something like this. Thus, when the motor on the left rotated at 3450 rpm the motor on the right would rotate at 1725 rpm. The second drawing is a close up from side and top of how it would be built.

Buy plans for the belt sander. ← Previous Post If you have a woman in the car, you may have a simple quick belt replacement—pantyhose. You could use what is called a "variable pitch" pulley, which is a pulley that allows the width of the groove to be adjusted. Which great mathematicians had great political commitments? Why has Pakistan never faced the wrath of the USA similar to other countries in the region, especially Iran? Shipments to WA, CO, CT, KS, OK, PA, VT, and HI have been suspended (more info). More reader built belt sanders. Homemade Edge Belt Sander Table. Since the belt is a fixed width, adjusting the width of the "variable pitch" pulley causes the belt to ride higher or lower in the groove, thus effectively adjusting the "pitch diameter" of the pulley. JavaScript seems to be disabled in your browser. When any of these belts begin to slip, the resulting friction can cause a piercing squeal. And, the outside diameter of pulley sizes is not always the effective diameter when using one style of belt as opposed to using another style of belt. 384 Wallis Street #2 How do I deal with my group having issues with my character? You could use an intermediate shaft and a combination of two pulley ratios. The "V" belt is one of the most effective belt solutions because of its strength, relative quietness, power transfer, and durability. What are possible causes for belt tensioner “chatter” at idle? Let's pretend that I could have installed the correct size pulley on both motors in the first place. In both of these situations, welding would help, but would not be needed as you can pick up some 1/8" to 3/16" thick metal strapping which can be bent in a vise and drilled to create the right sized holes. You would need to have fairly stout springs on either side. That's right, some simple pantyhose can act as a makeshift alternator belt until you find a proper solution, i.e. Here is an old Onan AC generator head. Making statements based on opinion; back them up with references or personal experience. The object in the middle would need to be your spring tensioner. One thing to note about this Tac is that the hour meter can not be reset. Because most engines are rated at 3600 RPM, you will note that many generator heads are also designed to be rotated at 3600 RPM. Maybe you reside on a boat, vacation in a remote cabin, or live off-grid like me. Asking for help, clarification, or responding to other answers. Knowing that the engine rpm must be at 3600 to develop full horsepower and also knowing that the Onan generator head needs to rotated 1800 rpm it becomes obvious that we can't just direct drive this particular generator with a gasoline engine. Next Post →. Alignment of the alternator is key, or you'll be wearing belts out or they will tend to jump off of the alternator. The making of @wwenxt Championship Belt [Real Gold] for AFT is now available. In that case you could remove the pump assembly from your washer and attach a generator head when needed in the winter, and in the spring you could remove the generator head and reattach the pressure washer pump assembly. Underneath of this, I'm assuming is some type of rubber mount, but the top part, where the very rusty nuts are at, could be used as another mounting point.
