Description

Novel combined type coupler

Technical Field

The utility model relates to an engine shaft coupling technical field, the novel combination formula shaft coupling that concretely relates to examination machine was used.

Background

The engine needs to be tested before being off line, the engine and related detection equipment need to be connected through a coupler during testing, coaxiality of an engine output shaft and the detection equipment is not high in some detection links, and the engine output shaft and the detection equipment are adjusted only by means of damping of the coupler. Along with the gradual promotion of engine power, the shaft coupling shock attenuation glue of current adoption is out of shape easily, and the shock attenuation effect is not good to the installation is difficult, and easy irreversibility deformation, life is not long.

The above background disclosure is only provided to aid in understanding the concepts and technical solutions of the present invention, and it does not necessarily belong to the prior art of the present patent application, and it should not be used to assess the novelty and inventive step of the present application without explicit evidence that the above content has been disclosed at the filing date of the present patent application.

SUMMERY OF THE UTILITY MODEL

The utility model provides an above-mentioned technical problem provide a novel combination formula shaft coupling that shock attenuation is effectual, long service life.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the novel combined type coupler comprises a connecting shaft key, damping rubber and a connecting disc; the front part of the connecting shaft key is a connecting shaft, and the rear part of the connecting shaft key is a groove disc; the shock absorption glue is distributed in the groove disc; the front part of the connecting disc is distributed in the groove disc and pressed behind the shock absorption glue, and meanwhile, the outer diameter of the front part of the connecting disc is smaller than the inner diameter of the groove disc; a plurality of springs are uniformly distributed on the inner side wall of the groove disc and extrude the outer wall of the front part of the connecting disc; the bottom surface of the groove disc and the bottom surface of the connecting disc are respectively provided with a first hollow hole and a second hollow hole; the first hollowed-out holes and the second hollowed-out holes are distributed at intervals; through holes are formed in the shock absorbing glue corresponding to the first hollowed-out holes and the second hollowed-out holes; the groove disc and the damping rubber penetrate through the second hollowed-out hole through a first bolt to be tightened; the connecting disc and the damping rubber penetrate through the first hollowed-out hole through a second bolt to be tightened; the aperture of the first hollow hole is larger than the head diameter of the second bolt; the aperture of the second hollow hole is larger than the head diameter of the first bolt.

Furthermore, a joint bearing is combined at the middle shaft of the groove disc; the middle part of the connecting disc is connected with the inner ring of the joint bearing through an upper tightening shaft.

Furthermore, the connecting shaft is a spline shaft.

Further, the damping rubber is in a ring shape.

The utility model has the advantages of compared with the prior art: the connection mode of the groove disc, the connection disc and the shock absorption glue of the utility model ensures that the connection is stable and the movement is more flexible; joint bearing who is equipped with makes the utility model discloses can bear stronger axial effort, through combine on the inside wall of recess disc to be equipped with the spring to and the damping rubber is ring shape, makes connection pad and connecting axle key can resist stronger radial effort, makes it possess more steady regulation effect to the not good rotation process of axiality, excellent in use effect.
