rotary kiln gearbox drive system problems

7. If the kiln drive motor control system responds to a speed change in a time period that is close to the time interval between two adjacent gear teeth, drive load cycling can occur with resonance characteristics. Some motor control systems have a variable resistor that can change the system response time to pinion speed change. If possible, the

Inching Drives What do they do How do they Work

Sep 29, 2011 Inching drives are units that provide slow-speed operation of conveyor or elevator systems in order to facilitate maintenance and inspection. An inching drive, which contains its own gearbox reducer to achieve the slower speeds, can be installed between the driving motor and the main drive system, or it can connect to the main drive system separately from the main motor.
