Service life improves, and both ends of the shaft is equipped with antifouling seat, and antifouling seat has blocked gap both ends open, avoids contamination dust, plays
Antifouling effect is suitble to be widely used and use, and can effectively solve the problems in background technique.
To achieve the above object, the technical solution that the utility model is taken are as follows:
A kind of high-antiwear self-lubricating axle sleeve, including axis body and post-receiving chamber, the axis body inside, which is run through, is equipped with post-receiving chamber, described
Axis body inner sidewall two sides offer ball slot, and ball slot inner cavity movable inlaying is connected with ball, and the axis body two sides are equal
Fuel feed hole is offered, and fuel feed hole extends to ball slot inner cavity, described fuel feed hole one end inner cavity is movably equipped with stopple, the shaft
Intracavitary chamber movable inlaying has shaft, is fixedly connected with antifouling seat at the top of the shaft.
Further, the axis body both ends open up fluted, and antifouling seat is located at groove inner cavity.
Further, the antifouling seat bottom surface linking has graphite pads.
Further, the shaft and axis body internal chamber wall junction are equipped with gap, and ball side extends to gap inner cavity
With shaft contacts.
Further, the ball slot inner cavity top and bottom are inlaid with connected nail, and ball is arranged by connected nail
In ball slot inner cavity.
Compared with prior art, the utility model has the following beneficial effects:
1. being equipped with ball slot in the internal chamber wall two sides of axis body, the inner cavity of ball slot is connected with rolling by connected nail
Pearl, and ball side in the gap inner cavity between shaft and internal chamber wall, is opened up through internal chamber wall in the two sides of axis body
There is fuel feed hole, and fuel feed hole extends to each ball slot inner cavity and works as, so pouring into lubrication to ball slot inner cavity by fuel feed hole
Oil, and fuel feed hole place inner cavity open at one end is movably equipped with stopple, stopple avoid lubricating oil and trickle oil inlet outer end of hole out, then turn
Axis rotation is lower to drive ball lateral rotation, makes ball that lubricating oil to be uniformly applied to shaft outer side wall surface, makes shaft so certainly
Dynamic lubrication, reduces friction, keeps its wear-resisting, and service life improves.
2. make to form gap between shaft and post-receiving chamber due to contacting support between ball and shaft, it is empty in order to prevent
Gap both ends permeability and lubricating oil are easy both ends is made to be covered with dust to pollute, and are equipped with groove at the both ends of axis body, the both ends of shaft connect
It is connected to antifouling seat, and antifouling seat is located just in groove inner cavity, so antifouling seat has blocked gap both ends open, avoids being infected with
Dust, plays the role of antifouling, avoids dust from entering in gap and contacts with ball, thus influence ball rotation flexibility ratio and
The rotation flexibility ratio for influencing shaft makes it generate larger friction effects service life, has in the bottom surface linking of antifouling seat
Graphite pads, graphite pads can promote the lubricity between antifouling seat and groove, since graphite is soft, has greasy sliding sense, has and promote
Lubricating action keeps its overall wear resistance good, improves service life so reducing the friction dynamics of antifouling seat and groove in this way.

Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
As shown in Figs. 1-2, a kind of high-antiwear self-lubricating axle sleeve, including axis body 1 and post-receiving chamber 2 run through on the inside of the axis body 1
Equipped with post-receiving chamber 2, the 1 inner sidewall two sides of axis body offer ball slot 3, and the 3 inner cavity movable inlaying of ball slot is connected with
Ball 4,1 two sides of axis body offer fuel feed hole 5, and fuel feed hole 5 extends to 3 inner cavity of ball slot, described 5 one end of fuel feed hole
Inner cavity is movably equipped with stopple 6, and the 2 inner cavity movable inlaying of post-receiving chamber has shaft 8, is fixedly connected at the top of the shaft 8 antifouling
Seat 9.
Wherein, 1 both ends of axis body open up fluted 10, and antifouling seat 9 is located at 10 inner cavity of groove.
Wherein, 9 bottom surface of the antifouling seat linking has graphite pads 11.
Wherein, the shaft 8 is equipped with gap 7 with 1 internal chamber wall junction of axis body, and 4 side of ball extends to 7 inner cavity of gap
It is contacted with shaft 8.
Wherein, 3 inner cavity top of ball slot and bottom are inlaid with connected nail 12, and ball 4 is set by connected nail 12
It is placed in 3 inner cavity of ball slot.
It should be noted that the utility model is a kind of high-antiwear self-lubricating axle sleeve, when work, in the internal chamber wall of axis body 1
Two sides are equipped with ball slot 3, and the inner cavity of ball slot 3 is connected with ball 4 by connected nail 12, and 4 side of ball is through interior
Cavity wall is in 7 inner cavity of gap between shaft 8 and internal chamber wall, has offered fuel feed hole 5 in the two sides of axis body 1, and into
Oilhole 5 extends to each 3 inner cavity of ball slot and works as, so pouring into lubricating oil, and fuel feed hole 5 to 3 inner cavity of ball slot by fuel feed hole 5
Place inner cavity open at one end is movably equipped with stopple 6, and stopple 6 avoids lubricating oil and trickles 5 outer end of fuel feed hole out, and then shaft 8 rotates
Lower 4 lateral rotation of drive ball, makes ball 4 that lubricating oil to be uniformly applied to 8 outer side wall surface of shaft, makes shaft 8 automatic in this way
Lubrication reduces friction, keeps its wear-resisting, and service life improves, and due to contacting support between ball 4 and shaft 8, makes shaft 8 and turns
Gap 7 is formd between axocoel 2,7 both ends permeability of gap and lubricating oil are easy both ends is made to be covered with dust to pollute in order to prevent,
The both ends of axis body 1 are equipped with groove 10, and the both ends of shaft 8 are connected with antifouling seat 9, and antifouling seat 9 is located just at 10 inner cavity of groove and works as
In, so antifouling seat 9 has blocked 7 both ends open of gap, contamination dust is avoided, plays the role of antifouling, dust is avoided to enter sky
It is contacted in gap 7 with ball 4, to influence the rotation flexibility ratio of ball 4 and influence the rotation flexibility ratio of shaft 8, makes its generation
Larger friction effects service life has graphite pads 11 in the bottom surface linking of antifouling seat 9, and graphite pads 11 can promote antifouling
Lubricity between seat 9 and groove 10 has since graphite is soft, has greasy sliding sense and promotes lubricating action, so reducing in this way
The friction dynamics of antifouling seat 9 and groove 10, keep its overall wear resistance good, improve service life.
