Torque limiter with unidirectional slide function

Abstract

The invention relates to the technical field of torque limiters, and particularly relates to a torque limiter with a unidirectional slide function. The torque limiter with the unidirectional slide function comprises an input sleeve, an input shaft and a connection flange, wherein the input shaft is slidably arranged at one end of the connection flange in the axial direction of the input shaft; a first limit mechanism used for limiting radial displacement of the connection flange is arranged on the input shaft; first springs are arranged in the connection flange and between the connection flange and the input shaft; and the input sleeve is located between the input shaft and the connection flange. The torque limiter with the unidirectional slide function only limits a torsion force transferred by a transmission system in one direction in a manner of slide during use, and automatically recovers connection after a case of overload disappears. The torque limiter with the unidirectional slide function can be used for weakening a reverse impact existing in the transmission system to play a role of protecting a fan gearbox and other equipment, and has an effect of shock absorption or damping.

Description

technical field

[0001] The invention relates to the technical field of torque limiters, in particular to a one-way slipping torque limiter. Background technique

[0002] The wind turbine drives the impeller to rotate through the natural wind, so that the impeller drives the gearbox. Finally, a coupling is installed between the gearbox and the generator to transmit power, so that the generator rotates and generates electricity. In order to prevent excessive torque between the gearbox and the generator, resulting in damage to the gearbox or the generator, a traditional torque limiter is usually installed on the coupling, and the traditional torque limiter is usually mainly used for positive overload protection. There is a reverse torque in the transmission system of the wind turbine, and the torque of the reverse impact is much smaller than the set slipping torque of the forward overload protection, which is not enough to trigger the slipping of the traditional torque limiter,...
