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.

Step 12: Find the corrected power rate and number of v-beltsrequired; We found the power rate. of the v-beltin step 6. Multiply the correction factors that you found in step 11 with the power rate to find the corrected power rate of the selected standard v-belt. Divide the design power with the corrected power rate of the v-belt.

The methods from the GB / T 11355 and GB / T 13575 can not calculate precisely the driving capability of the V-belt which had requirement of reliability. A new formula which can figure out the life

For a given belt length, the distance between the pulley axles can be calculated using the above formula if the diameters of both pulleys are known. For example, consider calculating the

shows two views of a dual V-belt drive arrangement. V-Ribbed Belts V-ribbed, or Poly-V belts, are flat belts with a series of ribs running longitudinally along the driving face that fit into grooves in a sheave. These belts are relatively thin with a well-supported tensile member. They are thinner and weigh less than V-belts.

Select the proper V-belt section. 23. 4. Determine the speed ratio. 28. 5. Choose the pulley datum diameter. 28. 6. Calculate the belt speed.

this manual contains all relevant technical informa- tion as well as the method for calculating drives with optibelt rB ribbed belts and optibelt rBS ribbed belt pulleys for mechanical engineering. the Optibelt range for ribbed belt drives is based on the stand- ards ISO 9982, RMA/MPTA IP-26 and DIN 7867.
