cast pulley

Correct belt installation can be very important when it comes to getting maximum life and efficiency from your belts. Take time to be sure that your belt pulleys are properly lined up with a straight edge and that they are not worn and cutting into the belts. Proper belt tension should be set with a belt tension tool that can also be purchased online and reset again after the first week or so of operation to allow for belts that stretch, and all belts will stretch. Most of the stretching takes place in first hours of operation so it is very important to re check vbelt tension after the belt has had some run time.

This system operates to either reduce or increase speed or torque, and for power transmission between shafts, especially those which are not axially aligned. These two complement each other wherein the belt balances the load while the pulley controls the speed. Understanding how they work can help you take advantage of their roles in enhancing motor performance, and at the same time, help you choose ones that are also cost-efficient.

Right now, there are a lot of belts available in the market that you can easily get your hands on. It would be a great help to know the factors that will help you decide what kind of belt to use. Some of the features that you need to look for in belts are their high level of efficiency and, at the same time, low level of maintenance. Another thing to consider is the maximum load and the initial tension of the belt. There is a limit to the load size before the belt slips and the initial tension plays a big role in determining this factor. Too little initial tension can result to a dead battery and the alternator belt slipping. On the other hand, too much initial tension will result to wear and tear of the belts and bearings.

Among the most popular belt drivers are the V-belts. Their wedge action can produce a lot of friction and increase the power transmission capability. They have an estimated 5% reduction and 93% efficiency. On the other hand, if you are looking for a belt system to work best with a vehicle, then you need the synchronous belt. It is also called timing belt pulley which can control the opening and closing of engine valves. When you are looking for toothed-belts that need little maintenance and re-tensioning, then the belt pulley is your best choice. On top of that, they are the most efficient, can run slip-free, and can work both in wet and oily surroundings.

When it comes to v-belts their’s more to just throwing them on and walking away. Unfortunately in most cases this is exactly what is done. Another misconception is that v-belts do not need to be replaced until they have completely broken and will not function at all. V-belts will stretch and start slipping long before they will break. V-belt dressing will buy you some short term time but is not the answer. A quality preventive maintenance program may include automatically replacing vbelts every six months depending on equipment run time.

V- belts pulleys differ from timing belt pulleys for the type of belt ( V-section) they fit in. HZPT has in stock a wide range of V- belt pulley of different types ( according to type and width of belts). The material used is cast iron EN-GJL-250 UNI EN 1561, and for only a few types it is steel C45 E UNI EN 10083-1. They have a small prebore that can be machined  according to  customers’ requirements. Moreover the most common types are available also with taperlock bore.
