Abstract
The utility model discloses a shaft bush which comprises a cylindrical bush body with openings at two ends. An annular groove surrounding the side wall of the bush is arranged on the outer side wall of the bush. At least one oil filling hole is arranged on the side wall of the bush. A plurality of axial strip-type oil grooves are evenly arranged on the inner wall of the bush. Chamfers are arranged on the openings at the two ends of the bush along the inner wall of the bush. By adoption of the design that the axial strip-type oil grooves are arranged on the inner wall of the bush, a shaft is enabled to drive lubricating oil in the oil grooves to form a layer of uniform oil film between the shaft and the inner wall of the bush at the time of rotating in the bush so as to enhance the lubricating effect of the bush. The annular groove on the outer wall of the bush is favorable for installation and fixation of the bush. Meanwhile, the chamfers are arranged on the opening ends so that operation of installation and replacement of the bush is more convenient and faster. Moreover, the shaft bush is simple in structure and low in production cost, and saves use cost.
Description
Technical field
The utility model relates to the mechanical structure that a kind of bearing connects, and is specially a kind of installation and changes easily muff.
Background technique
The rotation connection structure that axle and bearing are arranged in the mechanical structure, axle is rotatably installed in the bearing, because long-term use can cause the wearing and tearing between axle and bearing, Gu in order to improve the working life of axle, to use as a kind of sliding bearing, lining self adopts hardness material low, that wear resistance is good to be made at the sheathed lining of axle outer surface.Lining of the prior art is because friction factor is uneven, often needs lubricatedly, and existing lining lubrication effect is not good, and long-term use can cause the heavy wear of axle and lining, and the installation of lining changes operation and waste time and energy, and is convenient not.
The model utility content
The purpose of this utility model provides a kind of muff, and is not good to solve lining lubrication effect traditional in the prior art, and the problem of changing inconvenience is installed.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of muff, include the cylindrical sleeve body of an open at both ends, it is characterized in that: be provided with annular groove around sidewall on the described lining outer side wall, described lining sidewall is provided with at least one oil hole, evenly be provided with several axial bar shaped oil grooves on the described lining inwall, the uncovered of described lining two ends is provided with chamfering along inwall.
Described a kind of muff is characterized in that: described chamfering is 45 ° of chamferings.
The beneficial effects of the utility model are:
The utility model adopts at inwall and is provided with axial bar shaped oil groove design, that axle can drive lubricant oil in the oil groove when rotating and makes and form the uniform oil film of one deck between axle and the lining inwall in lining, to strengthen the lubrication effect of lining, annular groove on the outer wall is conducive to the installation of lining with fixing, simultaneously open-mouth end adopts chamfer design, faster and more convenient operation in the installation of lining and when changing, and the utility model is simple in structure, cost of production is low, has saved user cost.

Fig. 1 is sectional view of the present utility model.
Embodiment
As shown in Figure 1, a kind of muff, include cylindrical sleeve 1 body of an open at both ends, be provided with annular groove 2 around sidewall on lining 1 outer side wall, lining 1 sidewall is provided with at least one oil hole 3, evenly be provided with several axial bar shaped oil grooves 4 on lining 1 inwall, the uncovered of lining 1 two ends is provided with chamfering along inwall.
Chamfering is 45 ° of chamferings.
Claims (2)
1. muff, include the cylindrical sleeve body of an open at both ends, it is characterized in that: be provided with annular groove around sidewall on the described lining outer side wall, described lining sidewall is provided with at least one oil hole, evenly be provided with several axial bar shaped oil grooves on the described lining inwall, the uncovered of described lining two ends is provided with chamfering along inwall.
