Description

Shock mount and generator

Technical Field

The utility model relates to a vibration damper with a rubber spring in a generator, in particular to a vibration damper.

The utility model also relates to a generator.

Background

The shock-absorbing seat is a member connected between the power part and the fixed bracket of the generator, and the shock-absorbing pad made of deformable rubber on the shock-absorbing seat plays a role in reducing the transmission of the vibration of the power part to the fixed bracket. The structural components of the shock mount generally include a movable mounting for connecting to the power section, a stationary mounting for connecting to the stationary bracket, and a shock pad connected between the movable mounting and the stationary mounting. When the vibration-reducing device is used, the power part connected with the movable mounting piece and the fixed support connected with the Jing'an mounting piece can move relatively through the damping pad, so that vibration transmission is reduced. However, in practical use, it is found that the shock-absorbing seat is easy to damage the generator due to the fact that the power part or other parts connected to the movable mounting part have too large movement amplitude to strike other parts of the generator, or the shock-absorbing pad of the shock-absorbing seat is excessively stretched to damage the generator, so that the normal use of the whole generator is affected, for example, the vehicle-mounted generator is very easy to generate the problem.

The Chinese patent document CN 219809357U discloses a shock mount and a generator, which comprises a first connecting plate, a second connecting plate, a shock absorption block and a limiting plate, wherein one side of the first connecting plate is bent to form a first inclined plate, one end of the first inclined plate, which is far away from the first connecting plate, is inclined upwards, the second connecting plate is arranged above the first inclined plate, the bottom of the second connecting plate is bent to form a second inclined plate, the second inclined plate is inclined towards one side of the first connecting plate, the shock absorption block is arranged between the first inclined plate and the second inclined plate and is respectively connected with the first inclined plate and the second inclined plate, the limiting plate is detachably arranged on the second connecting plate, a coupler knuckle is arranged at the bottom of the limiting plate, and the coupler knuckle can hook the first inclined plate upwards. When the second connecting plate is pulled upwards in the vibration process of the engine, the second connecting plate can be limited to the maximum displacement amount upwards after the second sloping plate is hooked by the coupler knuckle due to the existence of the limiting plate, so that the safety problem caused by the fact that the engine impacts the oil tank due to overlarge vibration amplitude is avoided, and the safety is improved.

Although the shock mount of this prior art has solved the too big problem of striking the oil tank of engine vibration range, but the structure of whole shock mount is comparatively complicated, and processing cost is higher.
