Description

Technical Field

[0001] This utility model relates to the field of coupling technology, and in particular to a linear coupling. Background Technology

[0002] In mechanical transmission systems, couplings are key components connecting two shafts, and their performance directly affects transmission efficiency and equipment stability. Couplings are mainly used for transmitting rotary motion, but in situations requiring high-precision linear motion or complex operating conditions, linear couplings can effectively solve problems such as alignment errors, vibration absorption, and rigid transmission.

[0003] Early linear motion transmissions mainly relied on structures such as sliding guides and ball screws. However, under conditions of high speed, high precision, or installation deviations, these mechanisms are prone to wear, vibration, or decreased transmission efficiency due to misalignment.

[0004] Existing linear couplings are basically composed of two connecting bushings. When used between two connected shafts, if there is a linear tension deviation between the two shafts in the radial or axial direction, the tight structure of the existing coupling will easily cause the radial and axial deviation between the two shafts to occur, which can easily lead to vibration, noise and component wear, resulting in insufficient stability of the coupling.

The connecting component 4 is engaged between the first bushing assembly 1 and the second bushing assembly 2 and is used for linear deviation compensation of the coupling. Multiple screws 5 are used to connect the two connecting blocks 3 with the first bushing assembly 1 and the second bushing assembly 2. Through the screws 5, the connecting blocks 3, the first bushing assembly 1, the second bushing assembly 2, and the connecting component 4 form a complete linear coupling structure.

[0036] The first bushing assembly 1 includes a first sleeve body 11, a first locking block 12, and a first elastic component 13. The first sleeve body 11 is engaged and fixed with one of the connecting blocks 3 by a screw 5, which facilitates the easy assembly and disassembly of the connecting block 3 and allows the rotating shaft to be inserted into the inner cavity of the first sleeve body 11, making the connection between the rotating shaft and the first sleeve body 11 convenient. Multiple first locking blocks 12 are integrally formed and fixed at one end of the first sleeve body 11 near the second bushing assembly 2. Multiple first elastic components 13 are fixed in a ring array at one end of the first sleeve body 11. The first elastic components 13 are used for the connection between the first sleeve body 11 and the connecting component 4.

[0037] In addition, the second bushing assembly 2 includes a second sleeve 21, a second locking block 22, and a second elastic component 23. The second sleeve 21 is engaged and fixed with another connecting block 3 by a screw 5. Multiple second locking blocks 22 are integrally formed and fixed to one end of the second sleeve 21. The connecting component 4 is disposed between multiple first locking blocks 12 and second locking blocks 22, so that the connecting component 4 can realize synchronous rotational connection between the first sleeve 11 and the second sleeve 21. Multiple second elastic components 23 are fixed to one end of the second sleeve 21 in a ring array.

Multiple damping pads 42 are respectively in contact with the inner walls of adjacent first sleeves 11 and second sleeves 21. The damping pads 42 are made of elastic and wear-resistant rubber. The placement of the damping pads 42 at both ends of the gear 41 facilitates the connection between the first sleeves 11 and the second sleeves 21.
