Torque transmission control device and using method thereof

Abstract

The invention relates to the technical field of torque control equipment and method, in particular to a torque transmission control device and a using method thereof. The torque transmission control device is composed of a plurality of clutch groups, a piston structure corresponding to the clutch groups, and a clutch plate arranged on the outer side of an output shaft in a sleeving manner; one side of the clutch groups is matched with the clutch plate through a plurality of static friction plates, and the other side of the clutch groups is matched with a shell of the output shaft through a plurality of dynamical friction plates; and the piston structure is used for changing clearances among the static friction plates and clearances among the dynamical friction plates so that the output torque control is achieved. Compared with the prior art, the torque transmission control device has the features of rational design, compact structure, and easy installation and removal, and has the advantages that the torque transmission control device can be directly installed on the output or high-speed end of a torque output device, and the upgrading and improvement cost of an existing torque output device is reduced greatly.

Description

technical field [0001] The present invention relates to the technical field of torque control equipment and methods, in particular to a torque transmission control device and its usage method. Background technique [0002] At present, large-capacity, long-distance, and high-speed bulk material conveyors are widely used in the transportation of bulk materials such as coal and ore. There are mainly two ways to start the transmission device: one is the electrode, and the moment-limiting hydraulic Composed of a coupler and a reducer, because it is affected by the torque-limited hydraulic coupler during the drive transmission process, the start-up time is short, and the belt start cannot be precisely controlled according to the control curve requirements, and there are problems such as poor start-up stability and large impact , its serious consequences will cause transverse cracks in the conveyor belt, which becomes the biggest hidden danger of production safety; the other is com...

Problems solved by technology

[0002] At present, large-capacity, long-distance, and high-speed bulk material conveyors are widely used in the transportation of bulk materials such as coal and ore. There are mainly two ways to start the transmission device: one is the electrode, and the moment-limiting hydraulic Composed of a coupler and a reducer, because it is affected by the torque-limited hydraulic coupler during the drive transmission process, the start-up time is short, and the belt start cannot be precisely controlled according to the control curve requirements, and there are problems such as poor start-up stability and large impact , its serious consequences will cause transverse cracks in the conveyor belt, which becomes the biggest hidden danger of production safety; the other is composed of frequency conversion electrodes, frequency converters and reducers. The flatness of the curve is not high, especially the underground coal mine has explosion-proof safety requirements, the frequency converter is not yet competent, and the high-power technology is not very mature

The existing CST technology is mature, but it is not used for the upgrade of the existing motor (variable frequency motor) plus a gearbox. For example, the inventor’s prior application: CN201739448U discloses a controllable start-up transmission device, which is the first time that the CST The technology is applied to bulk material conveyors, but when this structure is applied to actual use, it is necessary to dismantle the existing motor gearbox equipment and replace the whole set of equipment, which is costly and not economical
