This manual covers the four classical V-belt cross sections and pulley groove sizes designated A, B, C, D. Dimensions of V-belts and pulleys together with basic design data are covered in this manual. This manual does not apply to automotive and agricultural drives. Nominal dimensions of the four cross sections are given in Table 1. Table 1.

DESIGN PROCEDURE FOR V BELT DRIVE STEP 1: MATERIAL SELECTION BELT Rubberized Fabric PULLEY Cast Iron STEP 2: Select suitable Belt cross-section based on power transmitted. (DDB7.58) STEP 3: Calculate diameter of smaller & larger pulley. 𝑖 = 𝑁 𝑛 = 𝐷 𝑑 Nd = nD Where, D- Larger pulley diameter, N-Smaller pulley speed d-Smaller

Step 1:Selection of cross section of belt based on power transmitted. For 50 kW V belt C (or) D can be selected. [Refer from PSG P.No 7.58] Here C section is selected for the power range is 7.5 - 75 kW.

A typical V-belt section is shown in Fig.13.3.1. The geometrical features of the belt section are indicated in the figure. The pitch line, which is also marked 

Belt drives transmit power between two or more rotating shafts, usually with parallel axes of rotation. The belts are looped over pulleys attached to the driver

Calculation of design load: Calculate the design load by assuming a larger factor of safety, say 15 (or find the design load by assuming g a factor of safety 2 to 2.5 times the factor of safety) From PSG data book pg.No.9.1 Design load= load to be lifted × Assume factor of safety 3.

Synchronous belt drives typically produce more noise than V-belt drives. Noise results from the process of belt tooth meshing and physical contact with the pulleys. Select PowerGrip GT2 or trapezoidal timing belts. Design with large pulleys with more teeth in mesh. Keep belts tight, and control tension closely.

V-belts are also less efficient than chain or synchronous belt drives. After installation, V-belt drives that are not retensioned or properly maintained may run at efficiencies as low as 85 to 90%

Jun 01,  · Figure 5 — Metric V-belt Profiles. The fractional horsepower V-belt profile is designed for light-duty applications such as lawnmowers, snow blowers, attic or furnace fans, etc. These belts have a thinner cross-section and lighter gauge tensile cord (Figure 6), making them more flexible and able to bend around small sheaves.

In another thread, I raised a question on the procedure to be used in changing a V-Belt in the following situation. 1. Driven shaft is vertical, and its centerline is fixed. 2. Driven pulley is mounted at the bottom part of the shaft, approx. 12" above the end, and about 8" above the lower bearing, i.e. pulley is between bearings. 3.

If the design has fixed, non-moveable centers (not a recommended design) do the following: A. Mount one sheave onto the shaft loosely and put the belt on it. B. Put the other sheave into the belt loop and slip it onto the other shaft (bushing loosely installed). C. Align the drive and tighten the bushings.

V-Belt Sheave Installation Step 1: Loosen moveable base bolts (or motor base bolts) and move sheaves close to facilitate installation of belt. See Table 1 for minimum installation allowance. If the design has fixed, non-moveable centers (not a recommended design) do the following: A. Mount one sheave onto the shaft loosely and put the belt on it.

2). The V-shape makes it easier to keep fast-moving belts in sheave grooves than it is to keep a flat belt on a pulley. The biggest 

The highest quality belts still lose nearly 50% of installed tension, while lower quality belts lose over 70% of installed tension. You cannot "feel" the correct tension on a V-Belt. On a test given to over 200 experienced maintenance personnel, only 1% tensioned a belt correctly using the "feel" method.
