V-Belt Drive Selection Handbook - baldor

A ratio is a proportional factor between two similar objects of different sizes. In a belt drive system, a ratio is used to determine the speed relation between two v-belt pulleys. The speed ratio would be stable if slippage did not occur; however as belt slip is inevitable, the ratio varies and is therefore only theoretical.

Calculation of V-Belt Tensions And Shaft Loads

V-Belts will transmit power satisfactorily over a wide range of tensions. An experienced user can develop a "feel" when a drive is tensioned within this range. However, in order to optimize belt life and performance and to avoid undue stress on shafts and bearings it is desirable to calculate and measure belt tension based on drive loads.

Belt Widths The belt widths are as follows: 18, 24, 30, 36, 42, 48, 54, 60, 72, 84, and 96 inches. The width of the narrower belts may be governed by the size of lumps to be handled. Belts must be wide enough so that any combination of prevailing lumps and finer material does not load the lumps too close to the edge of the conveyor belt.

Notes on Pulleys and Belts - gizmology

V-belts are not efficient, however. While they transfer torque effectively, they loose a bit of speed as the belt stretches under load. Maximum Load and Initial Tension. How much load can be put on a belt before it slips depends on a lot of stuff, but most importantly the initial tension, the force squeezing the pulleys toward each other ...

Motor Shaft Load Due to Belt Loading Equations and ...

Electric Motor Shaft Load Due to Belt Loading Equations and Calculator. The most common application that results in an overhung load on the shaft is a V-belt drive. V-belts are friction devices and depend on tension in the belts to prevent slipping. The following equation may be used to calculate the shaft load due to belt pull.

The belt also tends to wedge into the groove as the load increases—the greater the load, the greater the wedging action—improving torque transmission and making the V-belt an effective solution, needing less width and tension than flat belts. V-belts trump flat belts .
