9 Flat belts offer the following advantages over V-belts • They can be used in dusty and abrasive atmosphere and require no closed casing. • The design of flat-belt drive is simple and inexpensive. • They can be used for long centre distances, even up to 15 m. • The efficiency of fl at belt drive is more than V-belt drive. The major disadvantage of flat belt drives over V-belt drives

Power transmission by belt drive is one of the most common and universally used methods of transmission system when two shafts are parallel (up to 10 m) to each other as shown in Fig. 9.1. A belt drive consists of two parallel shafts and a pulley is mounted on each shaft. An endless belt runs over the surface of the pulley.

Open Belt Drive. In the case of an open belt drive, the driver pulley and the driven pulley rotates in the same direction. The Pulleys are placed in parallel with each other. This is the most common type of belt drive used in machines. Few examples are Flour Mills, Cam Shaft, Alternator, belt conveyor etc.

V-beltsare rugged – they provide trouble-free performance when given minimal attentioneven under adverse conditions. 2. V-beltsare clean – require no lubrication. 3.

Design of v belt drives complete notes ebook free download pdf V-belt drives are most recommended for shorter center distances. In comparison to flat belt drives, these drives are slightly less efficient. V belt can have transmission ratio up to 1:15 and belt slip is very small. As the belts are endless type, V-belt drives do not suffer

This paper consists of four separate parts: 1) Radial penetration of a V-belt, 2). Formulas for axial forces, 3) Additional slip in varispeed drives, 

V-belt drives provide many maintenance advantages that help in your daily struggle to reduce equipment repairs and to hold forced downtime to the lowest possible level. 1. They are rugged-they will give years of trouble-free performance when given just reasonable attentioneven under adverse conditions. 2. They are clean-require no lubrication.

V-belt Drive Design Process 1. Rated power of the driving motor/prime mover. 2. Service factor based on type of driver and driven load. 3. Center distance (adjustment for center distance must be provided or use idler pulley) 4. Power rating for one belt as a function of size and speed of the smaller pulley 5.

The belt drives are usually classified into the following three groups: 1. Light drives. Note : The V-belt and rope drives are discussed in Chapter 20.
