Crown is provided so that the belt should remain in the centre of pully rim. In the absence of crown the belt will slip sideways. - Deepak
The crown measurements of a flat pulley refer to the dimensions of the raised edges or sides that help keep the belt or rope centered on the pulley. Typically, these measurements include the height and width of the crown, as well as the diameter of the pulley itself. Accurate crown measurements are essential to ensure proper alignment and reduce slippage during operation. Specific dimensions can vary based on the application and design requirements of the pulley system.
Wing pulley is a type of conveyor tail pulley that has a flat bar welded to a gusset (like a T cross-section) then welded to a cylindrical drum. There's usually a crown on the T that goes the width of the pulley to maintain belt tracking, but flat wing pulleys are also available in the market.
to align a flat belt conveyor simply adjust the tail end pulley or the idler pulley, it is provided with adjuster bolt to adjust it in order to align the conveyor.
Yes, it is proper to align the pulley to increase tension on the side of the belt running off. Proper alignment helps keep the belt centered and minimizes wear on the pulleys and the belt itself. This ensures smooth operation and extends the life of the belt and pulleys.
There are three basic types of pulleys and belts. Three very common types would be round, v-shaped, and flat. Each type of belt requires a matching pulley type. For example, a flat-type belt would require a compatible flat shaped pulley, where the surface of friction is smooth and flat. Most other belts are some variation of these three types. Any of these types of belts may be ribbed, toothed, or some hybrid of any of the above types.
Starting from the crankshaft pulley and going clockwise looking at the pulleys, the belt goes thus: Ribbed side against the crankshaft pulley, then flat side against the tensioner pulley, ribbed side around the power steering pulley. Then the flat side against the idler pulley running ribbed side around the alternator pulley then down to theair con pulley running ribbed side around that and back to the crankshaft pulley.
Does the water pump pulley have grooves in it? If so, then the ridges should ride in those grooves. If the pulley is flat, the back side of the belt powers it. Here's a place to get diagrams: http://free-auto-repair-advice.blogspot.com/2007/12/serpentine-and-timing-belt-diagrams.html
The engine usually has an idler and/or tensioning pulley as well as a few pulleys that use the power of a traveling serpentine belt to drive components such as the alternator, a/c pump, etc. Any of the pulleys that have one or more grooves that assist to guide the belt(s) are, technically, sheaves. Idler or tensioner pulleys that are completely flat because the flat back of the belt rides on them are not sheaves, but are pulleys.
Not that I'm aware of. If you have a v-belt type pulley on the water pump, it runs CW. If you have a flat face pulley on the water pump, it runs CCW.
The trick to putting on most v belts is to understand the pulleys. The flat surfaced pulleys will contact the back of the belt. The v pulleys will face the v on the belt. On a chariot jr., you put the belt around the drive pulley on the motor first (v facing the pulley). From the front of the mower facing the seat, the left side of the belt comes up/around to the v blade pulley to your left. Next the belt goes around the idler pulley just to the right. Then the center blade pulley. At this point the belt actually will go around the idler tension pulley (the pulley with the spring attached to it.). But, you have two options here. To put the v belt around the blade v pulley to the far right first. Or, around the idler tension pulley first. Now here's where it gets tough. You have to take a crow bar or other type bar and pull the idler tension pulley around far enough to get the belt over it. That should do it.
goes around the engine pulley next both deck (blade pulleys) then put it around the tightener (blade engagement pulley) with the back Flat side of the belt against the pulley. make sure all the belt gaurds do not contact the belt with the blade engaged or dis-engaged. when you are installing the belt you will have to disconnect the deck lift rod to get the belt the other side of it or it will rub and ruin it. should be just a matter of pulling a cotter pin or push pin.
Serpentine-type belts have a flat profile with a number of grooves running lengthwise along the belt. These grooves are the exact reverse of the grooves in the outer edge of the pulley wheels; they increase the contact surface area, as well as prevent the belt from slipping off the wheel as it rotates.
