Design and construction of V belt drive is sunple and inexpensive and drive is complex and costlier. easy to maintain. 6. They have large dimensions and 6. V belt have short centre distance consume much higher space for which results in compact construction operation.

Procedure 1: Calculation of Design Horsepower Calculate the design horsepower from the following equation. Design Horsepower = Transmission Horsepower x Service Factor Refer to the DriveN Machines listed in Table 1 and select the corresponding service factor. DriveN Machine DriveR The machines listed below are rep- resentative samples only.

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

V-belt tensioning For the initial installation of optibelt RED POWER 3 V-belts, the same methods are used as for standard Optibelt V-belts. The tension values are to be calculated on the same basis or to be taken from the table on page 147. Once correctly tensioned optibelt RED POWER 3 V-belts need no re-tensioning. Application areas

Gates Super HC V-Belts combine modern high capacity material with the revolutionary "narrow" cross section pioneered by Gates. They can transmit up to 3 times the horsepower of conventional V-belts in the same drive space—or the same horsepower in 1/2 to 2/3 the space. Super HC belts can be used on all industrial integral horsepower drives.

Questions: A compressor, requiring 90 kW, is to run at about 250 r.p.m. The drive is by V-belts from an electric motor running at 750 r.p.m. The diameter of the pulley on the compressor shaft must not be greater than 1 metre while the centre distance between the pulleys is limited to 1.75 metre. The belt speed should not exceed 1600 m / min. Determine the number of V-belts required to transmit

TECHNICAL AND DRIVE DESIGN FOR V-BELTS 1.12.3 DO'S and DON'TS 1, Ensure perfect alignment of pulleys 2, The grooves should be free from burrs, sharp edges, rust, oil and grease. The guard should be provided to prevent this. Like This Not This 3, Belts used in a multiple drive should be of same manufacturer. 5.

V-Belt Drives Section 1 5. Inspect Sheaves A-4, A-9 Sheave condition and alignment are vital to V-belt life and performance. New V-belts should never be installed without a careful and thorough inspection of the sheaves involved. Particular attention should be given to these conditions. Replace sheaves if worn: a. Worn groove sidewalls b.

Abstract- This paper studies various parameters of designing the belt drives for power transmission. A new method is introduced here in this research work.

3.1.1 Determining Design Power (P d) The optimal belt drive tension is dependent on many factors. The goal is to tension the belts just enough to prevent them from slipping, however it is rare that all of the information necessary to do this is known. The formula for Design Power below covers the vast majority of belt drives.
