Coupler

Abstract

The invention discloses a coupler which comprises a first half coupler and a second half coupler which are provided with coupling bodies; the coupling bodies are respectively provided with a locating hole passing through the upper and the lower end surfaces of the coupling bodies; at least two convex blocks extends at one end of the coupling bodies in a convex way, and an inserting hole is formed between the two adjacent convex blocks; and the convex block and the inserting hole of the first half coupler can be blocked and jointed with the inserting hole and the convex block of the second half coupler. As the convex block of the first half coupler and the convex block of the second half coupler are blocked and jointed with each other in a crossing way, the coupler has simple structure, easy fabrication, convenient assembly and compact combination. Furthermore, as the coupling bodies of the first half coupler and the second half coupler are provided with the locating holes which are matched with shaft ends of connected shaft bodies, the combination is firm, and the coupling bodies and the connected shaft bodies can be prevented from sliding.

Description

technical field [0001] The present invention relates to a shaft coupling, in particular to a shaft coupling arranged coaxially for transmitting torque of two shafts. Background technique [0002] Couplings are mechanical parts used to connect two shafts in different mechanisms to rotate together to transmit torque. see figure 1 , which is an existing coupling, including a first half coupling 1 , a second half coupling 3 , and a connecting head 2 connecting the first half coupling 1 and the second half coupling 3 . The central position of the upper end face and the central position of the lower end face of the connecting head 2 are respectively provided with convex heads, and the upper end face of the first half coupling 1 and the lower end face of the second half coupling 3 are respectively provided. There is an insert groove matching the convex head, and the convex head is embedded in the insert groove, so as to connect the first half-coupling 1 and the second half-coupli...

AI Technical Summary

Problems solved by technology

[0003] However, the manufacturing precision of the first half-coupling 1 and the second half-coupling 3 of the coupling is high, and the two half-couplings need to be connected through the connector 2, the strength of the coupling is not large, and The coupling formed by the first half-coupling 1 and the second half-coupling 3 connected by the connecting head 2 is not compact in axial length, and is suitable for special (acid, alkaline) application environments in the PCB industry. In the middle, it is inconvenient to disassemble, and it is easy to cause the two halves of the coupling to be disconnected from the connector 2, and the connection is not smooth
