Problems solved by technology

[0002] In the prior art, there are many connection methods of couplings, generally in the form of upper and lower couplings. The upper and lower couplings adopt the pattern of pawls to cooperate with each other, and shock absorbing pads are added between the pawls. The disadvantage of this connection method is that the transmitted force is very small, and if the clearance fit is not good, it is easy to produce noise

Embodiment Construction

[0010] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0011] as attached figure 1 The shown coupling of the present invention includes an upper coupling 1, a lower coupling 2, a connecting screw 3 and a lock nut 4 for connecting the upper and lower couplings, and the lower coupling An elastic body 5 is sheathed at the joint between the device 2 and the connecting screw 3; an inner block 6 and an outer block 7 are respectively provided at both ends of the elastic body 5; the inner block 6 is located on the upper coupling 1, The lower coupling 2 is connected between the ends. The upper coupling 1 and the motor shaft 8 are matched through the upper connecting key 9; the lower coupling 2 and the reducer shaft 10 are matched through the lower connecting key 11.

[0012] In the present invention, through the structure of the elastic body 5 provided at the joint, when it is installed and conn...

Abstract

The invention relates to a coupler which comprises an upper coupler body, a lower coupler body, a connecting screw and a locking nut. The connecting screw and the locking nut are used for connecting the upper coupler body with the lower coupler body. The connection position between the lower coupler body and the connecting screw is sleeved with an elastic body. The two ends of the elastic body are provided with an inner stop sheet and an outer stop sheet respectively. The inner stop sheet is arranged between the connecting ends of the upper and the lower coupler bodies. Due to the fact that the elastic body is arranged at the connection position, certain elastic deformation is provided during installation and connection, and the connection strength of the upper and lower coupler bodies is enhanced. Due to the fact that the inner stop sheet and the outer stop sheet are arranged at the two ends of the elastic body, sliding of the upper and lower coupler bodies in the axial direction is limited, the upper and lower coupler bodies are prevented from colliding with each other, noise is lowered, the service life of the coupler is prolonged, and meanwhile the coupler has the advantages that replacement is convenient and rapid, disassembly and assembly are carried out at the same time, and the working efficiency is effectively improved.

Description

technical field [0001] The invention relates to a connection structure, in particular to a shaft coupling for a drive device suitable for escalators and moving walks. Background technique [0002] In the prior art, there are many connection methods of couplings, generally in the form of upper and lower couplings. The upper and lower couplings adopt the pattern of pawls to cooperate with each other, and shock absorbing pads are added between the pawls. The disadvantage of this connection method is that the transmitted force is very small, and if the clearance fit is not good, noise will easily occur. Contents of the invention [0003] The object of the present invention is to provide a shaft coupling with simple structure, firm installation, safety, reliability and good economical practicability in order to overcome the deficiencies of the prior art. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a shaft coupling,...
