Re: Conveyor Drive
Please tell us how this question differs from your prior posting September 27,2005 entitled:
"Dual Drive Load Sharing"
You received a number of responses which apparently did not answer your question. ■
Two Drives On A Single Pulley
Dear sir
I have received satisfactory reply of earlier thread about load sharing between two drives at different pulleys. This question is slightly different In case both motors are on same pulley on both sides coupled with fluid coupling whether some special care is to be taken. As in earlier case pulley to belt slip is possible in case slight rpm difference .

Re: Conveyor Drive
The concept of load sharing between fluid couplings is almost independent of drive locations. This assumes the motor speeds are near the same.
You are trying to match two coupling power measurements. Although the speed variation mechanism may differ (belt stretch, et al) the process to balance them is the same. ■
Re: Conveyor Drive
Dear Shri Rajeev,
The use of two drive units one on each side of the drive pulley is quite common. Such drive can have fluid couplings. In general, use the motor, gearbox and fluid coupling of identical size and practically matched torque speed characteristics. There should not be unusual situation about load sharing. Take appropriate precautions involving motor supplier and fluid coupling supplier. It is not possible to describe in this forum the calculation method about the response of the drives.

Conveyor drive
Dear sir
I consider two drives on a single pulley with Fluid couplings, one on each side of pulley.
What problem will I face in case slight difference in motor rpm or coupling slip is there.
Can somebody share his experience with such a situation?
