Abstract

The utility model relates to a gapless composite shaft sleeve, belonging to the technical field of the mechanism. The shaft sleeve is provided with a gapless steel sleeve and a steel backing pipe; a copper wire powder pipe is sintered and connected with the internal wall of a copper backing pipe. The copper wire powder pipe, the tetrafluoroethylene coating and the copper wire powder pipe are sintered and connected with the internal wall of the steel backing pipe. Then, the tetrafluoroethylene is pressed on the internal wall of the copper wire powder pipe in the form of rolling; the gapless steel sleeve is pressed and sheathed on the peripheral wall of the steel backing pipe. The utility model with convenient production and manufacture for the gapless composite shaft sleeve, favorable integrity, and convenient installation and operation is favorable for raising the assembly precision of a host machine.

Description

Seamless composite shaft sleeve
The utility model relates to the rotating shaft installation of the axle sleeve, particularly gear oil pump of rotating shaft installation usefulness and uses axle sleeve, belongs to field of mechanical technique.
At present, the axle sleeve that is used for the mesolow gear oil pump all is open types, is formed by the axle sleeve coiled sheet system that contains steel plate layer, copper wire bisque, tetrafluoroethylene layer.This axle sleeve, when pump housing aperture hour, in assembly process, hole dimension dwindles, be out of shape in causing easily, even endoporus uses the reamer fraising, but the tetrafluoroethylene of cover inwall will come off, and causes the oil pump life reduction.When pump housing aperture is big, cause the axle sleeve play easily, stop up oil through, wash out stifle when serious, influence oil pump working life.
The purpose of this utility model is exactly the deficiency at existing axle sleeve, and a kind of assembly precision height, seamless composite shaft sleeve easy to use are provided.
The purpose of this utility model realization has two kinds of schemes.
Scheme one: seamless composite shaft sleeve is provided with seamless steel sleeve 1, steel backing pipe 2, copper wire tube cell 3 and tetrafluoroethylene 4, and steel backing pipe 2 is connected with copper wire tube cell 3 sintering, and seamless steel sleeve 1 gland is on the outer wall of steel backing pipe 2, and tetrafluoroethylene 4 is coated with on the inwall that is pressed in copper wire tube cell 3.At steel backing inner tube wall sintered copper powder (copper mesh), at the copper wire tube cell inwall coated tetrafluoroethylene of sintering, tetrafluoroethylene and the roll extrusion of copper wire tube cell inwall is even again together with steel backing pipe 2.Gland seamless steel sleeve on the outer wall of steel backing pipe 2, and the outer garden of seamless steel sleeve carried out turning or grinding, improve garden degree precision.
Scheme two: seamless composite shaft sleeve is provided with seamless steel sleeve 1, copper wire tube cell 3, tetrafluoroethylene 4, and seamless steel sleeve 1 is connected with copper wire tube cell 3 sintering, and tetrafluoroethylene 4 is coated with on the inwall that is pressed in copper wire tube cell 3.Grinding or turning processing are carried out in the outer garden of seamless steel sleeve, improve garden degree precision.
The utility model is rational in infrastructure, simple, seamless, good integrity, manufactures easily, and is easy to install, helps improving the assembly precision of main frame.
Accompanying drawing is a structural representation of the present utility model, 1 seamless steel sleeve, 2 steel backing pipes, 3 copper wire tube cells, 4 tetrafluoroethylene among the figure.
Below in conjunction with accompanying drawing, narrate case study on implementation of the present utility model.
Example 1: sintered copper powder on the inwall of steel backing pipe 2, form copper wire tube cell 3, coated tetrafluoroethylene 4 on the inwall of the copper wire tube cell 3 that sinters into, and carry out roll extrusion by real, even, seamless steel sleeve 1 gland is assemblied on the outer wall of steel backing pipe 2.Again concentricity processing is carried out in the outer garden of seamless steel sleeve 1.
Example 2: adopt the axle sleeve of existing open type, the open type axle sleeve is pressed in the seamless steel sleeve, then concentricity processing is carried out in the outer garden of seamless steel sleeve.
