Abstract

The invention provides a torque limiter, which relates to the field of mechanical transmission and comprises a first transmission body, a second transmission body, a bolt, a spring, a press gasket and a locking adjusting nut. The first transmission body is provided with a gear disc surface A, the gear disc surface A is provided with a gear disc A, and a through hole A is arranged at the circle center of the gear disc A. The second transmission body is provided with a gear disc surface B, the gear disc surface B is provided with a gear disc B meshing with the gear disc A, and a through hole B is arranged at the circle center of the gear disc B. The press gasket is provided with a through hole C, and the bolt penetrates through the through hole A of the first transmission body, the through hole B of the second transmission body, the spring and the through hole C of the press gasket sequentially and presses the spring between the second transmission body and the press gasket by being matched with the nut. The torque limiter in the structure is arranged between an output shaft of a transmission device and a bearing shaft of an external load to serve as a connecting member, therefore, the transmission device is protected from being damaged due to abnormal torque rich caused by the outside affection.

Description

【Technical field】 [0001] The invention relates to the field of mechanical transmission, in particular to a torque limiter for connecting the output shaft of a driving and transmission device with a working machine or a carrying shaft of an actuator. 【Background technique】 [0002] Usually, the connection between the transmission output shaft and the external load is an unprotected connection. When the external load is artificially or otherwise caused by abnormal movement or reverse rotation, excessive torque will be generated, which will easily damage the transmission mechanism and the drive. device. [0003] For example, there is a kind of automatic reversing toilet at present, and the automatic reversing of this toilet is carried out through the output shaft of a motor and a bearing of the toilet cover, and when people carry out convenience, the output shaft of the motor rotates to drive the bearing of the toilet cover to rotate. However, in some cases, due to accidental ...
