Abstract
The utility model relates to a rolling friction transmission rotary typed high temperature sintering device, which comprises a high temperature sintering device main body, a furnace tube, a heating device which is arranged at the outer part of the furnace tube and a transmission shaft which is arranged on the high temperature sintering device main body in a rotary mode. The transmission shaft is connected with a motor through a first transmission mechanism, and the transmission shaft rotates following the motor. Two ends of the furnace tube are provided with furnace tube end sleeves. Certain clearance is formed between the inner surface of the furnace tube end sleeves and the outer surface of the furnace tube. Two second transmission mechanisms are arranged between the transmission shaft and the furnace tube end sleeves, so the two ends of the furnace tube can be driven by the furnace end sleeves through the friction to rotate following the rotation of the transmission shaft. The furnace tube end sleeves of the two ends of the furnace tube are fixed in two bearing seats, and the bearing seats are fixed at the two sides of the high temperature sintering device main body. Because the clearance exists between the outer surface of the furnace tube and the inner surface of the furnace tube end sleeve, the rolling friction transmission rotary typed high temperature sintering device can greatly reduce the torque that the furnace tube bears, and simultaneously, destructive torque caused by asynchrony can be automatically eliminated.
