Abstract
The utility model discloses a shaft sleeve which comprises a shaft sleeve body (1) and a clamping ring (2), wherein an installing groove (3) is formed in the outer surface of the shaft sleeve body (1); the clamping ring (2) is arranged in the installing groove (3) in a sleeving manner; two symmetrical positioning pin installing holes (4) are formed in the shaft sleeve body (1); a main oil groove (5) is formed in the inner surface of the shaft sleeve body (1); multiple oil filling holes (6) for communicating the main oil groove (5) and the installing groove (3) are formed in the shaft sleeve body (1). The shaft sleeve has the beneficial effect that the positioning pin installing holes are formed, so that the connection and positioning between the shaft sleeve and a shaft are facilitated through positioning pins; due to the formation of the oil filling holes, the filling of lubricating oil is facilitated; the time is saved; the work efficiency is improved; the lubricating oil is uniformly distributed in the shaft sleeve body and the lubrication performance is improved.
Description
Technical field
The utility model relates to a kind of axle sleeve.
Background technique
In machinery, the fixing of axle is generally to coordinate set screw to fix by coupling, and this means of fixation is for the rotation of high moment of torsion, can not effectively prevent the motion endwisely slipping with radial direction of axle.And in parts at the volley, axle is installed in axis hole, because long-term use can cause the wearing and tearing between axle and axis hole, therefore in order to improve the working life of axle, at the sheathed axle sleeve of axle outer surface, here axle sleeve uses as a kind of sliding bearing, and axle sleeve self adopts the good material of wear resistance to be made.Because axle sleeve adopts metal material, be made, but in existing metal material, friction factor is not very low, often still needs lubricatedly, if in use safeguard not prompt enoughly, can cause axle and axle sleeve heavy wear, even scrap.Owing to adding lubricant oil, need to be added on the inside surface of contact between axle and axle sleeve, interpolation is to add from axle sleeve side, when the wider width of axle sleeve, add side can not meet lubrication needs, after needing axle and axle sleeve to split, add again lubricant oil, whole process operation is loaded down with trivial details, extremely inconvenience.
Model utility content
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of axle sleeve that facilitates lubricant oil to add, increase work efficiency, improve greasy property is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of axle sleeve, it comprises axle sleeve body and collar, described axle sleeve body is cylinder type, the outer surface of axle sleeve body is provided with a mounting groove, described mounting groove is annular groove, the width of mounting groove and the degree of depth match with collar, collar is set in mounting groove, on the axle sleeve body of mounting groove bottom, be provided with two symmetrical locating stud mounting holes, be positioned on the internal surface of axle sleeve body of same axial position and be provided with main oil groove with mounting groove, described main oil groove is annular groove, be positioned at the oil hole that is also provided with the main oil groove of a plurality of connections and mounting groove on the axle sleeve body of mounting groove bottom.
On described collar, be provided with an opening.
Described oil hole is ladder-type, and plug is installed in oil hole.
Described plug is sunk screw, is provided with internal thread in oil hole, and sunk screw and oil hole are threaded connection.
On the internal surface of described axle sleeve body, be also provided with a plurality of secondary oil grooves, main oil groove and secondary oil groove are communicated with by the connecting passage being arranged on the internal surface of axle sleeve body.
The outward edge of axle sleeve body end is provided with chamfering.
The utlity model has following advantage: thereby be provided with locating stud mounting hole on axle sleeve body, facilitate axle sleeve by locating stud, to be connected location with axle; Being arranged so that of oil hole just can charging-up lubricant oil without pulling down axle sleeve body, has facilitated the interpolation of lubricant oil, has saved the time, increases work efficiency; Axle sleeve inside is provided with main oil groove and the secondary oil groove being interconnected, and axle sleeve body interior lubricant oil is evenly distributed, and has improved greasy property; Plug is installed and by collar capping plug top in oil hole, thus by seal oil in axle sleeve body, prevented the leakage of lubricant oil, collar has sealed positioning pin hole simultaneously, thereby make axle sleeve and Axile connection structure more stable.
