Abstract

The invention provides an elastic coupler. The elastic coupler comprises a first half coupler, a second half coupler and a rubber cushion. The first half coupler and the second half coupler are identical in structure. The first half coupler is made of stainless steel. The first half coupler is provided with groove portions and protrusion portions. The groove portions and the protrusion portions are arranged alternately. The first half coupler is provided with a shaft hole. The shaft hole is provided with a key groove. The rubber cushion is installed between the first half coupler and the second half coupler and attached to the groove portions. A screw hole is formed in the axial face of the first half coupler and communicates with the shaft hole. The center of the screw hole and the center of the key groove coincide. The height of each protrusion portion does not exceed the thickness of the rubber cushion. Each protrusion portion is provided with a chamfer. The elastic coupler is simple in structure, easy to manufacture, convenient to assemble and compact in combination, the elastic coupler is made of the stainless steel material, the torque bearing capacity and rigidity are improved, and the corrosion resistance requirement for the coupler under specific working conditions is met.

Description

technical field [0001] The invention relates to a shaft coupling, in particular to an elastic coupling. Background technique [0002] Elastic couplings are usually cut from metal round rods, and the commonly used materials are aluminum alloy, stainless steel, and engineering plastics. Flexible couplings utilize parallel or helical groove systems to accommodate misalignment and transmit torque precisely. Elastic couplings usually have good performance and have price advantages. In many practical applications of stepping and servo systems, elastic couplings are the preferred products. [0003] The elastic coupling in the prior art is composed of a first half coupling and a second half coupling, usually made of aluminum alloy, with a relatively complex structure, weak torque bearing capacity, and lack of a certain buffer. Contents of the invention [0004] (1) Technical problems to be solved [0005] The technical problem to be solved by the present invention is to provide...
