The role of the auxiliary drive is to rotate the kiln on a regular basis when the main motor or the main power go wrong, in order to avoid the bending of rotary kiln caused by the temperature difference between the top and bottom of it, and to ensure that the cylinder can stay in a given location in the brickwork or maintenance. The prime mover of the auxiliary drive, the majority of which is the motor, is power-supplied by the power different from the main motor and can also use Internal combustion engine to dispense with a power supply. There is an auxiliary reducer between the auxiliary motor and main gear box, the role of which is to achieve the request of the increase of speed ratio.
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 orYWZ-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. With its high quality products such as Symons cone crusher, Clinker rotary kiln, Sand washing plant, Belt conveyor, Stone crushing plant, Henan Hongxing mining machinery Co.Ltd has ascended in the front rank of the world in the exporting of mining equipments.
