Abstract

The invention discloses a shaft coupler convenient to disassemble. The shaft coupler convenient to disassemble comprises a first half-shaft coupler and a second half-shaft coupler, wherein the first half-shaft coupler and the second half-shaft coupler are fixedly connected through at least two pin shafts; the pin shafts are uniformly distributed on the circumference of a connecting flange for the first half-shaft coupler and the second half-shaft coupler; the first half-shaft coupler is fixedly connected with an input shaft; the second half-shaft coupler is fixedly connected with an output shaft. The shaft coupler convenient to disassemble has the beneficial effects of improving the reliability of the shaft coupler as a shaft sleeve delivers a torque between the shaft coupler and a drive shaft, and a bolt and a flat key are adopted for connection in the connecting process, and reducing the disassembling difficulty of the shaft coupler and the part processing precision as a too high magnitude of interference of the shaft coupler in an assembling process is unnecessary.

Description

Easy-to-dismount coupling

Technical field

The present invention relates to a kind of coupling for transmitting torque, particularly the easy-to-dismount coupling of one.

Background technique

Existing coupling is often subject to certain restrictions when dismantling; therefore; the most frequently used method passes through hammering exactly; but hammering usually can make transmission shaft wear and tear, pull or scroll key; keyway broadens, so that destroy the original size of part, and the difficulty of repairing these sizes is larger; and some size cannot be repaired at all, thus whole coupling is caused to damage.

Summary of the invention

For above-mentioned technical problem, the object of this invention is to provide the easy-to-dismount coupling that a kind of convenient disassembly does not affect again parts size precision.

The present invention is achieved by the following technical programs: a kind of easy-to-dismount coupling, comprise the first half-coupling and the second half-coupling, described first half-coupling is fixedly connected with by least two bearing pins with the second half-coupling, and described bearing pin is distributed on the circumferential surface of the first half-coupling and the second half-coupling adpting flange; Described first half-coupling is fixedly connected with input shaft, and described second half-coupling is fixedly connected with output shaft.

Wherein, described first half-coupling is connected respectively by axle sleeve with between output shaft with input shaft and the second half-coupling, and described axle sleeve is separately fixed on the first half-coupling and the second half-coupling by bolt.

Wherein in order to improve the reliability that moment of torsion transmits, described axle sleeve is connected with difference flat key between input shaft and output shaft.

Plate washer is respectively equipped with in order to prevent described bearing pin two ends.

Beneficial effect: the present invention transmits the moment of torsion between coupling and transmission shaft by axle sleeve, connection procedure is connected by bolt and flat key, therefore improve the reliability of coupling, and the magnitude of interference of coupling in assembly process does not need excessive, reduce the dismounting difficulty of coupling and the machining accuracy of part.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

Embodiment

Below in conjunction with drawings and Examples, the invention will be further described.

As shown in Figure 1, a kind of easy-to-dismount coupling, comprise the first half-coupling 1 and the second half-coupling 2, described first half-coupling 1 is fixedly connected with by four bearing pins 3 with the second half-coupling 2, and described bearing pin 3 is distributed on the circumferential surface of the first half-coupling 1 and the second half-coupling 2 adpting flange; Described first half-coupling 1 is fixedly connected with input shaft 4, and described second half-coupling 2 is fixedly connected with output shaft 5.Described first half-coupling 1 is connected respectively by axle sleeve 6 with between output shaft 5 with input shaft 4 and the second half-coupling 2, and described axle sleeve 6 is separately fixed on the first half-coupling 1 and the second half-coupling 2 by bolt 7.Described axle sleeve 6 with between input shaft 4 and output shaft 5 respectively flat key 8 be connected.Described bearing pin 3 two ends are respectively equipped with plate washer 9.

The present invention transmits the moment of torsion between coupling and transmission shaft by axle sleeve, connection procedure is connected by bolt 7 and flat key 8, therefore improve the reliability of coupling, and the magnitude of interference of coupling in assembly process does not need excessive, reduce the dismounting difficulty of coupling and the machining accuracy of part.
