Abstract

The utility model discloses a bearing bush type bearing. According to the bearing bush type bearing, hole channels communicating contact surfaces and non-contact surfaces of bearing bushes are arranged at the interiors of the bearing bushes, and oil is injected into the hole channels, so that lubrication between bearing bushes and bearing steel rings is realized; contaminated lubricating oil is squeezed out of the bearing during oil injection; therefore, a maintaining procedure is simplified, and the service life of the bearing is prolonged.

Description

A kind of split sleeve bearing

Technical field

The utility model relates to a kind of split sleeve bearing, belongs to Component field.

Background technique

Traditional bearing is because its non-removable structural characteristics, so maintenance will seem more difficult, in most of situation, all can solve by direct replacing the problem of maintenance, and in the situation that ask for something precision is higher, first the fabricating cost of precision bearing is just higher, and the often reduction of disassembling the precision that can cause rotatingshaft to bearing, affect quality of processing.

Model utility content

The purpose of this utility model is: a kind of technological scheme that can address the above problem is provided.

The utility model is realized by the following method:

A kind of split sleeve bearing, comprise some bearing shells, described bearing shell comprises: and two surface of contact of bearing outer ring inner ring, towards two non-contact faces in two outsides of bearing, two non-contact faces of described bearing shell one of them or two are processed with through hole A above, on two surface of contact of described bearing shell, be evenly processed with some through hole B, described through hole A and through hole B are communicated with at the inner passing hole channel of bearing shell.

As further innovation of the present utility model, on two surface of contact of described bearing, be processed with some grooves, described through hole B is distributed in the bottom surface of described groove.

As further innovation of the present utility model, described bearing shell is ceramic material, and the connected pore channel between described through hole A, through hole B and described through hole A and through hole B is that entirety is fired and formed.

beneficial effect

1. the utility model is by arranging the duct that is communicated with bearing shell surface of contact and non-contact face in bearing shell inside, by oiling in duct, realize lubricating between bearing shell and bearing steel ring, simultaneously in oiling, also the lubricant oil having polluted before can be squeezed bearing, simplify the operation of maintenance, extended the working life of bearing.

2. the utility model is by arranging some grooves at the contact surface of bearing shell, by these grooves, make lubricant oil can better cover the surface of contact surface of bearing, groove has also played oil extraction simultaneously, store the effect of lubricant oil, improved the lubricity of bearing and the simplification of maintenance, reliability.

3. bearing shell of the present utility model adopts ceramic one to fire to form, and than processing on steel bearing shell, one is fired method and had more easy manufacturing procedure, and the better intensity of integrity is higher simultaneously.

Embodiment

Below in conjunction with accompanying drawing, be described further

As shown in Fig. 1 ~ 4, a kind of split sleeve bearing, comprise some bearing shells, described bearing shell comprises: and two surface of contact of bearing outer ring inner ring, towards two non-contact faces in two outsides of bearing, two non-contact faces of described bearing shell one of them or two are processed with through hole A3 above, on two surface of contact of described bearing shell, be evenly processed with some through hole B2, described through hole A3 and through hole B2 are communicated with at the inner passing hole channel of bearing shell;

On two surface of contact of described bearing, be processed with some grooves 1, described through hole B2 is distributed in the bottom surface of described groove 1;

Described bearing shell is ceramic material, and the connected pore channel between described through hole A3, through hole B2 and described through hole A3 and through hole B2 is that entirety is fired and formed;

By the duct that is communicated with bearing shell surface of contact and non-contact face is set in bearing shell inside, by oiling in duct, realize lubricating between bearing shell and bearing steel ring, simultaneously in oiling, also the lubricant oil having polluted before can be squeezed bearing, at the contact surface of bearing shell, some grooves are set, by these grooves, make lubricant oil can better cover the surface of contact surface of bearing, groove has also played oil extraction simultaneously, store the effect of lubricant oil, bearing shell adopts ceramic one to fire and forms, than processing on steel bearing shell, one is fired method and is had more easy manufacturing procedure, the better intensity of integrity is higher simultaneously.

Claims

1. a split sleeve bearing, comprise some bearing shells, described bearing shell comprises: and two surface of contact of bearing outer ring inner ring, towards two non-contact faces in two outsides of bearing, it is characterized in that: two non-contact faces of described bearing shell one of them or two are processed with through hole A above, on two surface of contact of described bearing shell, be evenly processed with some through hole B, described through hole A and through hole B are communicated with at the inner passing hole channel of bearing shell.

2. a kind of split sleeve bearing as claimed in claim 1, is characterized in that: on two surface of contact of described bearing, be processed with some grooves, described through hole B is distributed in the bottom surface of described groove.

3. a kind of split sleeve bearing as claimed in claim 1, is characterized in that: described bearing shell is ceramic material, and the connected pore channel between described through hole A, through hole B and described through hole A and through hole B is that entirety is fired and formed.
