Abstract

The invention relates to the technical field of overload starting of a conveyor for a working face of an underground coal mine, in particular to a clutch type high-power efficient mechanical torque converter. Due to caving or top failure of the working face of the underground coal mine with poor conditions, the conveyor for the working face frequently has the problem of delay unloading or incapability of starting, coal can only be manually cleaned, and production efficiency is seriously affected. The clutch type high-power efficient mechanical torque converter comprises a permanent magnet coupling transmission system, a planetary transmission system and a hydraulic control friction clutch system, wherein the permanent magnet coupling transmission system is used for transmitting normal torque and disconnecting overload torque, and the hydraulic control friction clutch system is used for inputting the output torque of an amplification driving system of the planetary transmission system, limiting the maximum output torque of the driving system and slowing down load fluctuation. The clutch type high-power efficient mechanical torque converter solves the problem of delay unloading or incapability of starting of the conveyor for the working face in overload.

Description

technical field [0001] The invention relates to the technical field of overload start-up of conveyors on working faces in coal mines, in particular to a clutch-type high-power and high-efficiency mechanical torque converter. Background technique [0002] On the underground working face of coal mines with poor coal mining conditions, the working face conveyor often has the problem of being crushed or unable to start, but this technical field has not yet attracted attention. At this stage, the research hotspots of the transmission technology of working face conveyors at home and abroad are concentrated on the protection of the transmission system, various soft starts, lubrication, cooling, overload and vibration monitoring. [0003] Soft start methods such as valve-controlled speed-regulating hydraulic couplings, frequency-variable speed-regulating motors, and fluid-viscous clutches only slow down the change process of the load when starting, jamming, and stopping, reducing da...
