Description

Bearing bush assembly

Technical Field

The utility model relates to a part on the machinery, a concretely design bearing bush subassembly.

Background

The bearing bush is a part of the sliding bearing, which is contacted with a shaft, in the sliding bearing, the bearing bush is in a two-piece semi-cylindrical concave surface or an integrated pipe body shape, the shaft is generally fixed at the axis position by an upper bearing bush and a lower bearing bush, and a very thin oil film is required between the bearing bush and the shaft during working, and the oil film plays a role in lubricating and supporting the shaft. If an oil film cannot be established, direct friction exists between the bearing bush and the rotating shaft, the bearing bush is burnt out by high temperature generated by the direct friction, and higher temperature is generated even after the oil film is used, so that certain risk still exists for the bearing bush.

Disclosure of Invention

In order to solve the above problems, an object of the present invention is to provide a bearing bush assembly with a heat dissipation structure, which reduces the temperature of the bearing bush and prolongs the service life of the bearing bush.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a bearing bush subassembly, includes slide bearing, pivot and axle bush, and the pivot setting is in slide bearing's axis position, and axle bush inner wall butt is in the pivot, and the outer wall butt of axle bush is in on slide bearing's the interior pore wall, the pivot on two limit washer of fixedly connected with, the axle bush sets up two limit washer's interval position be equipped with annular recess on the limit washer, it has the through-hole to open in the bottom of recess, be connected with the blade on the lateral wall of through-hole, this blade orientation inside the recess, the axle bush on be equipped with the corresponding through-hole of this through-hole slide bearing's both sides be equipped with respectively with the communicating air vent of through-hole.

The inner hole of the sliding bearing is provided with a yielding groove, and the outer wall of the bearing bush is abutted against the bottom of the yielding groove.

The inner hole wall of the bearing bush is provided with a copper plating layer, and the copper plating layer is provided with an annular oil storage tank.

Oil storage pits are uniformly distributed on the copper plating layer.

The utility model discloses a this kind of structure, pivot drive limit washer at the rotation in-process and rotate, and the last blade of limit washer can produce the wind regime, and this wind regime passes the through hole on the axle bush and carries out certain heat dissipation to the axle bush for the heat that axle bush and pivot friction produced carries out timely radiating action, and the physical properties of having guaranteed the axle bush does not receive the temperature to influence, and the life that makes the axle bush is longer.

The invention is further described with reference to the accompanying drawings and the detailed description.

Drawings

FIG. 1 is a block diagram of an embodiment of the present invention;

fig. 2 is a perspective view of a spacing washer according to an embodiment of the present invention.

Detailed Description

The present invention will be specifically described below by way of examples.

As shown in fig. 1 and fig. 2, the embodiment discloses a bearing bush 3 assembly, which includes a sliding bearing 1, a rotating shaft 2 and a bearing bush 3, wherein the rotating shaft 2 is disposed at a central axis position of the sliding bearing 1, an inner wall of the bearing bush 3 abuts against the rotating shaft 2, an outer wall of the bearing bush 3 abuts against an inner wall of the sliding bearing 1, two limit washers 4 are fixedly connected to the rotating shaft 2, the bearing bush 3 is disposed at a spacing position between the two limit washers 4, an annular groove 41 is disposed on the limit washer 4, a through hole 42 is formed at a bottom of the groove 41, a vane 43 is connected to a sidewall of the through hole 42, the vane 43 and the through hole 42 are integrally formed by punching, and the through hole 42 and the vane 43 are circumferentially and uniformly distributed, it should be noted that the vane 43 must face the inside of the groove 41, if the vane 43 would be damaged by friction with the inner wall of the sliding bearing bush 1 when the rotating shaft, the slide bearing 1 is provided with vent holes 5 on both sides thereof, which communicate with the through-holes 31.

Be equipped with the recess of stepping down 11 on slide bearing 1's the hole, 3 outer walls butt of axle bush are at the tank bottom of recess of stepping down 11 for axle bush 3 is fixed in this recess of stepping down 11, can be through such structure axle bush 3 with slide bearing 1's cooperation more reasonable reliable.

The inner hole wall of the bearing bush 3 is provided with a copper plating layer 6, and the copper plating layer 6 is provided with an annular oil storage tank 61. Copper has better heat-conducting property, improves the radiating effect, and the oil storage tank 61 can make lubricating oil keep certain storage simultaneously, improves lubricated persistence.

Oil storage pits (not shown) are uniformly formed above the copper plating layer 6. Such oil storage pockets serve as the oil storage grooves 61, and further improve the storage of lubricating oil, improve the lubricating performance, and prevent friction overheating.

Through the technical scheme, the rotating shaft 2 drives the limit washer 4 to rotate in the rotating process, the blades 43 on the limit washer 4 can generate a wind source, the wind source penetrates through the through hole 31 in the bearing bush 3 to dissipate heat of the bearing bush 3 to a certain extent, heat generated by friction of the bearing bush 3 and the rotating shaft 2 is dissipated in time, the physical performance of the bearing bush 3 is guaranteed not to be influenced by temperature, and the service life of the bearing bush 3 is longer.
