Strengthen the round platform and not only can improve the structural strength of hole part, moreover through the setting of elasticity kicking block, can show improvement antiskid and grab power, not only make the bearing keep better fixed strength after the installation, through the elasticity of elasticity kicking block, can further strengthen fixed connection intensity when the bearing installation, and when the bearing was dismantled, lead to under the promotion of elasticity, also help promoting the bearing and move to the outside, consequently, the bearing also will become more light easy when the installation.

Description

Shaft head bushing

Technical Field

The utility model relates to a machinery pivot accessory field, specific sleeve is inlayed to axle head that says so.

Background

The spindle nose is inlayed and is put usually in the assembly antifriction bearing in machinery for rotate with all kinds of axle products and connect, and current spindle nose is inlayed and is put usually through hard cooperation equipment, through long-time use back, and the bearing can be because the assembly is improper, thereby leads to easy not hard up, consequently, the intensity and the stability of installation are still not enough, and the bearing is also more arduous when the installation. There is therefore room for further improvement.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a simple structure is reliable, and the intensity and the stability of bearing installation are good, and the cover is inlayed to the shaft head that the bearing is also easier in the installation.

In order to achieve the above object, the utility model provides a following technical scheme:

the shaft head bushing comprises an end cover with an inner hole, a bearing is arranged in the inner hole, a reinforcing round table is arranged at the periphery of the inner hole, a plurality of elastic jacking blocks are uniformly arranged in the reinforcing round table and comprise pressure springs and jacking blocks connected with the pressure springs, one end of each jacking block faces towards the inner hole and is exposed out of the reinforcing round table to be in close contact with the peripheral surface of the bearing.

Preferably, the top block is made of anti-skid rubber.

Preferably, the end of the top block is in a slope shape with an inward increasing degree.

Preferably, a plurality of fillets which are arranged in sequence are arranged on the inner side surface of the reinforcing circular truncated cone and the surface of the end part of the top block.

Preferably, the cross-section of the fillet is trapezoidal.

Compared with the prior art, the beneficial effects of the utility model are that:

strengthen the round platform and not only can improve the structural strength of hole part, moreover through the setting of elasticity kicking block, can show improvement antiskid and grab power, not only make the bearing keep better fixed strength after the installation, through the elasticity of elasticity kicking block, can further strengthen fixed connection intensity when the bearing installation, and when the bearing was dismantled, lead to under the promotion of elasticity, also help promoting the bearing and move to the outside, consequently, the bearing also will become more light easy when the installation.

Through the setting of the kicking block tip of slope form, can make things convenient for the bearing to follow the light push of one side direction of acute angle on the one hand, avoid the bearing to appear the card pause in the elasticity kicking block position when the installation moreover to further guarantee mounting structure's intensity and stability, with the help of the slope, the bearing also becomes more light easy when the installation.

FIG. 2 is a diagram of: the utility model discloses a schematic diagram I of structural section in the side view direction;

FIG. 3 is a diagram of: the utility model discloses a structural section schematic diagram of side view direction is two.

In the figure: 1. the end cover 2, the inner hole 3, the bearing 4, the reinforcing circular truncated cone 5, the elastic jacking block 6, the pressure spring 7, the jacking block 8 and the fillet.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 3, the spindle head bushing comprises an end cap 1 having an inner hole 2, a bearing 3 is disposed in the inner hole 2, a reinforcing circular truncated cone 4 is disposed at the periphery of the inner hole 2, a plurality of elastic jacking blocks 5 are equally disposed in the reinforcing circular truncated cone 4, each elastic jacking block 5 comprises a compression spring 6 and a jacking block 7 connected with the compression spring 6, and one end of each jacking block 7 faces the inner hole 2 and is exposed out of the reinforcing circular truncated cone 4 to be in close contact with the peripheral surface of the bearing 3.

Strengthen the round platform 4 and not only can improve the structural strength of hole 2 part, moreover through the setting of elasticity kicking block 5, can show improvement antiskid power of grabbing, not only make bearing 3 keep better fixed strength after the installation, moreover through the elasticity of elasticity kicking block 5, can further strengthen fixed connection intensity when bearing 3 is installed, and when bearing 3 is dismantled, lead to under the promotion of elasticity, also help pushing bearing 3 to move to the outside, consequently, bearing 3 also will become more light easy when the installation. In order to further improve the anti-skid holding power, the jacking block is made of anti-skid rubber.

The end of the top block 7 is in a slope shape which increases inwards, namely, one end is in an acute angle shape. Through the 7 tip settings of kicking blocks of slope form, can make things convenient for bearing 3 to follow the light push of one side direction of acute angle on the one hand, avoid bearing 3 to wait to appear blocking in 5 positions of elasticity kicking block when the installation moreover to further guarantee mounting structure's intensity and stability, with the help of the slope, bearing 3 also becomes more light easy when the installation.

The inner side surface of the strengthening circular truncated cone 4 and the surface of the end part of the top block 7 are provided with a plurality of fillets 8 which are arranged in sequence. The cross-section of fillet 8 is trapezoidal shape, sets up through the structure of fillet 8, can further improve the antiskid and grab power to effectively guarantee the intensity and the stability of bearing 3 installation.

Those not described in detail in this specification are within the skill of the art. Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
