Abstract
The invention discloses an elastic shaft coupling. The elastic shaft coupling comprises a shaft fixing disk and a shaft fixing disk cover which covers the shaft fixing disk; spring grooves are formed in the shaft fixing disk; a rotary table is arranged between the shaft fixing disk and the shaft fixing disk cover; clamping grooves which are corresponding to the spring grooves are formed in the rotary table; spiral springs which are installed in the clamping grooves are clamped in the spring grooves. According to the elastic shaft coupling, stress on a shaft from excessive turning angles can be eliminated and the springs are good in buffering effect due to the compression of the springs which are arranged inside the shaft coupling; coaxial error influences during installation is greatly reduced due to the fact that positioning of the rotary table which is arranged inside the elastic shaft coupling is performed through a floating spring; using space is not needed to be enlarged due to the fact that the springs having different elastic force can be selected according to using conditions; larger starting torque and sudden halt of a driven shaft can be buffered, motor overloading is protected, the shaft coupling is prevented from sliding or damaging, and gear abrasion is reduced; the fatigue resistance is large and spare parts for replacement are sufficient due to the fact that a mature technology that the springs are used for buffering is used; the design is simple and dismounting and maintenance are convenient.
