Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that if a key block is used to connect the first rotating shaft and the second rotating shaft, when the first rotating shaft continuously switches between forward rotation and reverse rotation, the key block will gradually collide with the first key groove and the second rotating shaft. The side wall of the second keyway deforms the key block. After a long time of use, since the key block cannot be tightly pressed against the first and second rotating shafts, when the driving motor switches the direction of rotation, the rotation of the second rotating shaft will lag. Phenomenon, which in turn reduces the transmission accuracy between the shaft and the shaft

Abstract

The present application relates to a coupling structure, which relates to the technical field of couplings, comprising a first rotary shaft and a second rotary shaft, the first rotary shaft and the second rotary shaft are coaxially arranged, and a first shaft is coaxially provided on the first rotary shaft Tightening mechanism, a sleeve is arranged between the first tightening mechanism and the second rotating shaft, one end of the first tightening mechanism is pressed against the outer peripheral surface of the first rotating shaft, and the other end of the first tightening mechanism is pressed against the sleeve On the inner peripheral surface of the sleeve, the sleeve is coaxially and fixedly connected to the second rotating shaft, or a second tightening mechanism is arranged between the sleeve and the second rotating shaft, and one end of the second tightening mechanism is pressed against the outer circumference of the second rotating shaft. On the surface, the other end of the second holding mechanism is pressed against the inner peripheral surface of the sleeve. The present application can prevent relative rotation between the first rotating shaft and the second rotating shaft, and improve the transmission accuracy between the first rotating shaft and the second rotating shaft.

Description

technical field [0001] The present application relates to the field of couplings, and in particular, to a coupling structure. Background technique [0002] The shaft is a mechanical part that supports the rotating part and rotates with it to transmit motion, torque or bending moment. [0003] refer to figure 1 , At present, when precise transmission is required between shafts, rigid transmission must be used, and when rigid transmission is used, most of the shafts are connected by key blocks 800 . When using the key block 800 to connect, the first keyway 110 is formed on the first shaft 100, the second keyway 220 is formed on the second shaft 200, and the key block 800 is clamped in the first keyway 110 and the second keyway 220 at the same time. A connecting sleeve 700 is sleeved on the first rotating shaft 100 and the second rotating shaft 200 , a third key groove 710 is defined on the inner peripheral surface of the connecting sleeve 700 , and the key block 800 is also ...
