Abstract
The utility model provides an eccentric bearing, which relates to a bearing. The utility model mainly comprises an outer ring, an inner ring, a rolling body flower basket and rolling bodies, the utility model is characterized in that an inner hole of the inner ring is an eccentric hole; the inner side wall of the eccentric hole is provided with a vertical key groove. The eccentric bearing has the advantages of simple structure and convenient use, implements eccentric function without an eccentric shaft, causes an eccentric mechanism to be greatly simplified, causes the mechanical working of the eccentric mechanism to be implemented in a labor saving, time saving and easy assembly way, and reduces the cost of the eccentric mechanism.
Description
The utility model relates to a kind of bearing.
As everyone knows, bearing has an outer ring and an inner ring, and a hole concentric with bearing arranged on the inner ring, and the rolling element gaily decorated basket is arranged between outer ring and inner ring, in the rolling element gaily decorated basket rolling element is installed.When the needs bearing is worked under eccentric state, must be in the concentric hole of bearing inner race the setting-up eccentricity axle, the processing eccentric shaft takes a lot of work, time-consuming, difficulty of processing is big, eccentric stiffener manufacture cost height, eccentric shaft is difficult with the bearing assembling.
The purpose of this utility model is that a kind of do not need to process eccentric shaft, axle and the easy capacity eccentric bearing of bearing assembling will be provided.
The purpose of this utility model is achieved in that the endoporus of inner ring is an eccentric opening, and a vertical keyway is arranged on the madial wall of eccentric opening.
In the such scheme,,, overcome the shortcoming that processing eccentric shaft difficulty is big, manufacture cost is high, reduced working strength of workers, eccentric stiffener is greatly simplified so do not need to process eccentric shaft because the endoporus of inner ring is an eccentric opening; Because the madial wall at eccentric opening has a vertical keyway, institute has reached the purpose of this utility model so that capacity eccentric bearing is simpler with the axle assembling.This capacity eccentric bearing is simple in structure, easy to use, does not need eccentric shaft just can realize eccentric function, and eccentric stiffener is greatly simplified, make simultaneously eccentric stiffener machining saving of labor, save time, it is easy to assemble, and has reduced the manufacture cost of eccentric stiffener.
Be described further in conjunction with the embodiments with reference to the accompanying drawings below.
Fig. 1 is a sectional structure chart of the present utility model.
Fig. 2 is the plan view of figure (1).
Embodiment 1: capacity eccentric bearing has an outer ring 1 and an inner ring 5, it is eccentric opening 3 that one hole is arranged on the inner ring 5, one vertical keyway 4 is arranged on the madial wall of eccentric opening 3, keyway 4 leaves on the thicker sidewall of inner ring wall, keyway 4 vertically connects the inner ring wall, between outer ring 1 and inner ring 5 the rolling element gaily decorated basket 6 is arranged, in the rolling element gaily decorated basket 6 rolling element is installed, rolling element is a ball 2.
Embodiment 2: rolling element can be roller, roller or the like, and other and embodiment 1 are together
During use, at lathe Che Yigen axle, axially mill a keyway on the sidewall of axle, axle is inserted in the eccentric opening of capacity eccentric bearing inner ring, the keyway in the keyway on the axle and the inner ring eccentric opening aligns, and carries out key connecting, and this assembling work promptly comes to an end.
Claims (3)
1, a kind of capacity eccentric bearing mainly comprises outer ring, inner ring, the rolling element gaily decorated basket, rolling element, it is characterized in that: the endoporus of inner ring is an eccentric opening, and a vertical keyway is arranged on the madial wall of eccentric opening.
2, capacity eccentric bearing according to claim 1 is characterized in that: described keyway is opened on the thicker sidewall of inner ring wall, and keyway vertically connects the inner ring wall.
