Abstract

The invention discloses a friction overtorque protecting structure and relates to the technical field of friction overtorque protecting structures. The friction overtrorque protecting structure comprises a drive end flange, friction plates, a copper bush, a pressure plate, a pressing plate, a driven end flange and a disc spring. One end of the drive end flange is sleeved with the pressure plate. The driven end flange is arranged between the pressure plate and the drive end flange. The friction plates are arranged on the end surfaces of the upper and lower sides of the driven end flange correspondingly. The friction plates make contact with the drive end flange. The copper bush is arranged in the position, making contact with the drive end flange, of the inner side of the driven end flange.The end, away from the drive end flange, of the pressure plate is connected with one end of the disc spring. The other end of the disc spring is connected with the pressing plate. When the friction overtorque protecting structure is disengaged, torque can still be transmitted, normal operation of a unit can be guaranteed, and it is guaranteed that a main machine has no runaway phenomenon; disengaging can be tolerated for a plurality of times; automatic reset is achieved, no operation is needed, and after overload torque is eliminated, synchronous reset can be achieved as a main machine is started; and the slipping torque precision is high and adjustable, the slipping torque is mainly achieved by adjusting the compression amount of the disc spring, and since the disc spring is stable in performance, the adjusting precision and repeating precision are high.

Description

Technical field: [0001] The invention relates to the technical field of friction over-torsion protection structures, in particular to a friction over-torsion protection structure. Background technique: [0002] With the development of the transmission system, the operating conditions of each transmission unit are getting worse and worse. At present, most units have irregular instantaneous over-torque phenomena. In order to avoid damage to the unit caused by over-torque, the traditional solution is to leave sufficient safety margins for all parts of the unit when designing the unit, which greatly increases the installation cost of the entire unit. Therefore, it is necessary to design an over-torque protection structure, which can perform overload protection when the unit is over-torque, and does not need to leave much margin in the design of other parts. Invention content: [0003] The object of the present invention is to overcome the shortcomings of the above-mentioned p...
