Safety coupling of vehicular dry-type screw air compressor

Abstract

The invention relates to a safety coupling of a vehicular dry-type screw air compressor, which is designed for resolving the technical problem that an existing like product is poor in structural stability and safety protection effect. The safety coupling comprises a motor end flange and a compressor end flange, wherein the motor end flange is connected with a motor end, the compressor end flange is connected with a compressor end, and both the motor end flange and the compressor end flange are provided with locking screws. The safety coupling is characterized in that one end of the motor end flange is fixedly connected with a first transitional flange, one end of the compressor end flange is fixedly connected with a second transitional flange, the outside of the first transitional flange is connected with the outside of the second transitional flange via a safety transitional pin in a positioning manner, and the inside of the first transitional flange is movably connected with the inside of the second transitional flange via a center shaft. The safety coupling is simple in structure, stable in driving torque and reliable in safety protection, is suitable, or can be used as an improved structure of a like product.

Description

technical field [0001] The invention relates to a safety coupling, which is a safety coupling of a vehicle-mounted dry screw air compressor. Background technique [0002] The safety coupling is a mechanical torque limiter that can quickly cut off the connection between the motor and the main shaft, thereby eliminating the destructive effect of inertial forces. For ordinary machinery, including conveyor transmissions, office machinery and various instruments and meters, mechanical torque limiters such as shear pin safety couplings can provide good safety protection. [0003] Existing safety clutches, such as the authorized announcement number CN2073957U published in the Chinese patent literature, the authorized announcement date was March 27, 1991, and the name of the utility model is "safety coupling". , one of the half-couplings has a V-shaped groove, and the other half-coupling is equipped with a set of springs and steel balls. The principle is to rely on the pressing for...
