Abstract

The invention discloses a flexible torque increment coupler for soft start. The flexible torque increment coupler is composed of a planetary gear transmission mechanism, a flexible torque transfer structure, an overload protection mechanism and a rotating speed switching mechanism. An internal gear and a planetary carrier output shaft in the planetary gear transmission mechanism are connected through the flexible torque transfer structure and the overload protection mechanism. Enlarged torque can be generated in the start process of a heavy load motor, a buffering effect is achieved, instant start currents can be reduced, and the heavy load start problem of the motor is solved. Flexible torque increments can be generated according to fluctuation loads or clamping stagnation of a scraper conveyer in the equipment running process, peak loads of the motor and a transmission part are reduced and absorbed, mechanical and grid impact caused by the peak loads is weakened, and the motor runs stably; the service life of the transmission part is prolonged; and grid impact and electric appliance burndown caused by heavy loads and fluctuation loads in the start process and the running process are retarded.

Description

technical field [0001] The invention belongs to the technical field of soft start of heavy-duty equipment, in particular to a flexible torque incremental coupling used for soft start. Background technique [0002] In the future world energy pattern, the role of coal is very important. Facing the rapid development of modern industry, the consumption of coal continues to increase, which promotes the continuous development of large and extra-large mines, making the scraper conveyors at home and abroad are moving towards large conveying capacity, high power, long distance, high strength, development in the direction of high performance. With the continuous increase of the performance parameters of the scraper conveyor, its conveying capacity is also continuously improved. [0003] However, when the scraper conveyor stops unexpectedly, the large amount of coal on the conveyor, the roof fall after the shutdown, and the coal falling from the sides make it difficult for the motor ...
