Auxiliary motor should be equipped with brakes to prevent kiln’s reversal caused by the emphasis of materials and bricklaying when the motor stops. The kiln reversal rate is often close to or above the normal speed, if at that time the auxiliary drive is not torn off and the reducer will become an accelerator, in that case the speed of auxiliary reducer and the motor will be over the nomal speed and reach a million revolutions per minute, so as to cause danger . Therefore, the brake and auxiliary motor must be turned on or power out at the same time. The brake can use the electromagnet type or YWZ-hydraulic push rod brake. Because of the bad bearing lubrication of chocks, wheel and drive part in the low speed, prolonged use of the auxiliary drive is not suitable and generally the continuous operation should not be more than 15 minutes.
It is equipped with clutch between the output shaft of the auxiliary reducer and the into shaft of main gear box, and its role is to separate the auxiliary transmission and main drive when the kiln operates nomally. There are no special requirements on the clutch, the common types are helical gear (Jaw) and the dowel pin type, and overrun the (one-way) clutch can also be used . Overrun clutch can introduces the auxiliary motor torque into the main gear box, and at that time if main motor drives the drive shaft of main gear box by higher speed in the same direction, the clutch will be in the disengaged position and play the role of separating.
In addition to the use of the overrun clutch, the main motor and auxiliary motor cannot rotate at the same time if the clutch is not in the disengage state. To this end, the electrical chain is required between the two machines. In order to ensure the safety and reliability of operation, there should be a mechanic-electrical interlock between the clutch and main motor to prevent the start of main motor when the clutch is not disengaged.
