Description

Vibration isolator for shaft

Technical Field

The utility model relates to a damping vibration isolation mounting especially relates to an inlay vibration isolation mounting who adorns in the shaft coupling.

Background

The coupling is a mechanical part for firmly coupling a driving shaft and a driven shaft in different mechanisms to rotate together and transmitting motion and torque. When a power machine such as an electric motor and a diesel engine is connected with a driven shaft of a driven machine through a coupling, the running vibration of the electric motor and the diesel engine is necessarily transmitted to the driven machine through the coupling, so that the existing coupling cannot block and isolate the transmission and diffusion of the mechanical vibration. Mechanical vibration can reduce mechanical dynamic precision and service performance, so that the service life of a machine or a structure is reduced, and even failure and damage are caused; the mechanical vibration can not only cause bolt looseness, sealing leakage and part fracture, but also cause the movement precision of equipment to be poor, the working performance to be reduced and even the equipment cannot work at all; the vibration can also generate noise, and the noise can pollute the environment and cause harm to the physiology and the psychology of people.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that an axle vibration isolator that can separation shaft coupling initiative side vibration to driven side diffusion biography cloth is provided to the above-mentioned not enough that prior art exists.

In order to solve the technical problem, the vibration isolator for the shaft of the utility model comprises a central shaft sleeve, wherein two radial plates are fixedly arranged on the central shaft sleeve, a radial plate buffer cushion is clamped between the two radial plates, a corresponding buffer ring is sleeved on each radial plate, a corresponding wheel rim is sleeved on each buffer ring, and a wheel rim buffer cushion is clamped between the two wheel rims; the periphery of the buffer ring is alternately provided with buffer ring embedded teeth and buffer ring embedded grooves, and two side faces of the buffer ring are provided with buffer ring side grooves; the wheel rim is characterized in that the inner hole surface of the wheel rim is alternately provided with wheel rim cogs and wheel rim caulking grooves, the buffer ring cogs are embedded in the wheel rim caulking grooves, and the wheel rim cogs are embedded in the buffer ring caulking grooves.

Further, the spoke plate is fixedly installed on the central shaft sleeve through a spoke plate bolt.

Further, the two oppositely arranged rims are fixedly connected with each other through the rim bolts.

Furthermore, the buffer ring is sleeved on the corresponding spoke plate through a central hole of the buffer ring.

Compared with the prior art, the structure has the beneficial technical effects that: at first the utility model discloses an axial wheel rim blotter and radials blotter, the transmission of separation and absorption shaft coupling axial vibration can be effectively adopted, adopts radial buffering ring separation and absorption shaft coupling radial vibration again, has the vibration isolation damping effect of axial and two radial directions, especially the utility model discloses in adopted the buffering ring that sets up side by side to the both sides face of each buffering ring all is provided with buffering ring kerve, makes the rigidity performance of whole buffering ring obtain optimizing, can reduce the vibration transmissivity of natural frequency annex vibration effectively, increases the vibration damping effect. The buffer ring and the rim are matched and connected with each other through corresponding cog teeth and caulking grooves; the connection reliability of the vibration isolator is improved, the structure is reasonable, and the connection strength is high.
