Description

Technical Field

[0001] The utility model relates to a bearing seat, in particular to a bearing seat with vibration reduction and noise reduction. Background Art

[0002] The turntable bearing seat is a large and extra-large bearing seat with a special structure that can accept comprehensive loads. It has the characteristics of compact structure, flexible rotation, and easy installation and maintenance. Where there is a bearing, there must be a support point. The inner support point of the bearing is the shaft, and the outer support is what is often called the bearing seat.

[0003] In the prior art, when the bearing rotates, the bearing seat will also vibrate. The vibration of the bearing seat causes the bolts to loosen, thereby affecting the stability of the bearing seat. Utility Model Content

[0004] The purpose of the utility model is to provide a bearing seat with vibration reduction and noise reduction to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a shock-absorbing and noise-reducing bearing seat, comprising a bearing seat body, wherein bolt channels are provided on both sides of the base of the bearing seat body, a shock-absorbing ring is fixedly installed in the bolt channel, and the bearing seat body is fixedly installed by bolts through the bolt channels.

[0006] The shock-absorbing ring includes a ring shell, an annular elastic plate and an elastic member. The annular elastic plate is installed in the ring shell through the elastic member. The elastic member includes a convex support column and a spring ring. The spring ring is sleeved on the convex support column. The bottom end of the convex support column is fixed on the inner wall of the ring shell, and the front end extends into a groove opened on the back wall of the annular elastic plate.

[0007] A plurality of limiting grooves are arranged on the inner side wall of the bolt channel, and the bolt is fixedly installed through the bolt channel. A sub-bolt groove is arranged in the bolt, and a plurality of limiting through grooves corresponding to the limiting grooves one by one are arranged on the groove wall of the sub-bolt groove. An arc-shaped elastic part is arranged in the limiting through groove, and the sub-bolt is screwed into the sub-bolt groove.

[0008] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0009] 1. When the bearing seat body is subjected to force and vibration, the swing of the bolt due to the relaxation of the vibration is weakened by the damping ring, which reduces the swing amplitude of the bolt after the bolt is relaxed, ensures the stability of the bolt during the whole process, and prevents the bolt from further loosening and disengagement;

[0010] 2. The utility model provides a plurality of limiting grooves on the inner wall of the bolt channel, the bolt is screwed into the bolt channel to fix the bearing seat body, and a sub-bolt groove is provided in the bolt, and a plurality of limiting through grooves corresponding to the limiting grooves are provided on the groove wall of the sub-bolt groove, and an arc-shaped elastic member is provided in the limiting through groove, and the sub-bolt is screwed into the sub-bolt groove. At this time, the arc-shaped elastic member is deformed by force and enters the limiting groove. This design strengthens the tightness of the bolt and improves the anti-seismic performance of the bolt. On this basis, an annular skirt is provided on the peripheral side of the bolt, and a plurality of bolt through holes are provided on the circumference of the annular skirt, and bolt grooves corresponding to the bolt through holes are provided on the bearing seat body, and the small bolts are screwed into the bolt grooves through the bolt through holes to tighten the bolts, thereby improving the tightness of the bolts.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1

[0021] See also Figure 1-3 , a bearing seat with shock absorption and noise reduction, bolt channels 2 are provided on both sides of the base of the bearing seat body 1, and a shock absorbing ring 3 is fixedly installed in the bolt channel 2. The shock absorbing ring 3 includes a ring shell 31, an annular elastic plate 32 and an elastic member 33. The annular elastic plate 32 is installed in the ring shell 31 through the elastic member 33. The elastic member 33 includes a convex support column 331 and a spring ring 332.
