subject: Guide To Selecting Timing Belt Pulleys [print this page] Technological advancement in the past few years has made the way for machines more robust and precise than ever. In the manufacturing sector, electric motors play a vital role. Through the years, their efficiency has been completely revolutionized many of times for maximum efficiency. In any electric motor intended for commercial and industrial use, one of the most familiar systems used is the belt and pulley.
Belt and Pulley System
This system works to either reduce or increase speed or torque, and for power transmission between shafts, especially those which are not axially aligned. They go with each other wherein the belt balances the load while the pulley controls the pace. Learning how they work will help you make the most of their roles in enhancing motor performance, and at the same time, help you choose ones that are also cost-efficient.
Variables Impacting Functionality
Today, there are tons of belts in the market that you can very easily purchase. It is a great help to be aware of the factors that will enable you to decide what type of belt to use. Some of the attributes 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. Not enough initial tension can result to a dead battery and the alternator belt slipping. On the other hand, an excessive amount of initial tension will lead to wear and tear of the belts and bearings.
Guidelines in Finding a good Belt
You cant simply go around buying any belt for your machines. There are a variety of belts that you may find high quality but will render useless if it is not well suited for the kind of machine you want to use it for. It is then essential that you take time to obtain information about your own piece of equipment. Take into account the load the machine will usually work with as well as the hours of production and operation that you need the machine for. Keep in mind not to be too frugal with the price. If you do, you could possibly spend more on maintenance and repairs later on.
Top Belt Options
One of the most widely used 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're looking for a belt system to operate best with a vehicle, then you'll 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 most suitable choice. On top of that, they are the most efficient, can run slip-free, and can work both in wet and oily conditions.
