Description

TECHNICAL FIELD

[0001] The present application relates to the mechanical technical field, especially to a buffer type coupling and a torque machine. BACKGROUND

[0002] The coupling is a mechanical part used to connect two shafts or a shaft and a rotating part in different mechanisms, rotate together in the process of transmitting motion and power, and normally not disconnected. Meanwhile, the coupling is also used as a safety device to prevent the connected parts from bearing excessive load, and plays a role of overload protection.

[0003] The coupling in the prior art comprises a driving shaft sleeve and a driven shaft sleeve. The driving shaft sleeve is fixedly connected with a common connecting disc through bolts. The common connecting disc and a patterned gear are provided with screw through holes and bolt through holes. A set screw and a connecting bolt are respectively arranged through the screw through holes and the bolt through holes to fixedly connect the common connecting disc and the patterned gear. The patterned gear is concentrically arranged with a patterned groove connecting disc. Long teeth on the patterned gear are connected with tooth grooves of the patterned groove connecting disc. The patterned groove connecting disc is fixedly connected with the driven shaft sleeve through bolts. The number of the long teeth is six, which are uniformly arranged at an interval of 60° along a circumference. The number of the tooth grooves is six, which are uniformly arranged at an interval of 60° along the circumference. The diameter of the tooth grooves is greater than that of the long teeth. In the use process of the coupling, the driving shaft sleeve is driven to rotate by an output shaft of a driving motor. The common connecting disc and the patterned gear are synchronously rotated by the driving shaft sleeve. The patterned groove connecting disc is rotated by the patterned gear. The driven shaft sleeve is rotated by the patterned groove connecting disc. The rotating part is driven to move by the driven shaft sleeve.

[0004] For the above-mentioned related coupling, since the coupling rigidly connects the driving motor and the rotating part, when the driving shaft sleeve starts, the rotating part connected with the driven shaft sleeve is subjected to an impact load under the action of an inertial load. Since the driving shaft sleeve and the driven shaft sleeve are rigidly connected, a large impact torque is formed, which affects the service life of the coupling. CONTENT OF THE UTILITY MODEL

[0005] In order to prolong the service life of the buffer type coupling, the present application provides a buffer type coupling and a torque machine.

[0006] In the first aspect, the present application provides a buffer type coupling, which adopts the following technical scheme:

[0007] A buffer type coupling comprises an input disc, an output disc, a positioning main shaft and a buffer assembly. The input disc, the buffer assembly and the output disc are sequentially arranged on the positioning main shaft.

[0008] The buffer assembly comprises a buffer disc, a plurality of sets of supporting blocks and a plurality of strong magnetic blocks.

[0009] The input disc, the buffer disc and the output disc are arranged in sequence along the axial direction of the positioning main shaft, and the input disc, the buffer disc and the output disc rotate coaxially with the positioning main shaft;
