Torsion overload safety protection device

Abstract

The invention discloses a torsion overload safety protection device which is provided with a framework fixed by corresponding annular press plates and tension bars. Nuts and springs are arranged on the lower portions of the two upper ends of the tension bars. The annular press plates are provided with sliding bearings. A driving shaft penetrates through the upper end of a position between the annular press plates in a transverse mode, and a driven shaft penetrates through the lower end a position between the annular press plates in a transverse mode. A friction plate is fixed between the driving shaft and the driven shaft, and is composed of a driving friction plate and a driven friction plate. A friction piece is fixed between the driving friction plate and the driven friction plate. Surface bearings are arranged at two ends of the driving shaft and the driven shaft. The torsion overload safety protection device not only has the function of adjusting torsion, but also has the advantages of adjusting the torsion conveniently at the same time.

Description

technical field [0001] The invention relates to a transmission and safety protection technology, in particular to a torque overload safety protection device. Background technique [0002] In some important transmission systems, in order to prevent damage to equipment or other safety accidents due to torque overload, it is generally necessary to set an over-torque safety protection device in the transmission system. Although the existing over-torque safety protection device is in principle and structure The above are not the same, but generally there is a defect that the torque cannot be adjusted; some although the torque value can be adjusted, but there is a defect that the torque adjustment is troublesome. Contents of the invention [0003] The invention aims at the technical defects of the existing torque overload safety protection device, and provides a novel torque overload safety protection device. [0004] The technical scheme adopted by ...
