Description

Bearing lubrication drainage mechanism

Technical field

The utility model relates to a kind of numerical control machine tool bearing drainage mechanism, espespecially relates to a kind of bearing lubrication drainage mechanism.

Background technique

In numerical control machine tool course of working, need to carry out oil lubrication to the bearing of numerical control machine tool driving mechanism, ensure that its rotation is smooth and easy, simultaneously, when numerical control machine tool carries out cutting, need that cooling liquid is carried out to cutter and rinse cooling, cooling liquid is easy to enter in bearing along the gap of bearing support and medium, the moisture content such as cooling liquid all can accumulate in bearing after entering bearing from bearing support gap, be difficult to quick discharge, cause bearing damage, in order to avoid cooling liquid enters bearing, the main oil sealing that adopts seals bearing at present, but, so just cause, waste oil in bearing cannot be discharged automatically, need regularly manually to open it cleaning waste oil, complex operation, affect work efficiency.

Model utility content

In order to overcome above-mentioned defect, the utility model provides a kind of bearing lubrication drainage mechanism, and this bearing lubrication drainage mechanism structure is simple, moisture can be stoped to enter bearing, and ponding can be discharged outside bearing support fast, extends bearing working life.

The utility model in order to the technological scheme solving its technical problem and adopt is: a kind of bearing lubrication drainage mechanism, comprise ball screw, bearing, bearing support, bearing cap and first, second medium, described ball screw one end is formed with installation shaft, bearing and first, second medium is sheathed on outside installation shaft respectively, and first, second medium is closely against bearing shaft respectively to two ends, bearing support is the step-like structure that one end internal diameter is greater than the other end internal diameter, one end that bearing cap is large with bearing support diameter can be dismantled and is fixedly connected with, being formed between bearing cap and bearing support be able to the containing space of accommodating bearing, bearing cap and bearing support are just sheathed on first of bearing and two ends thereof, outside second medium, described bearing cap is provided with lubricant oil oil inlet passage bearing cap end face outside be communicated with the inner side end of contact bearing end face, bearing cap and bearing support are respectively equipped with the lubricant oil oil drain passage radially running through extension, two oil drain passages are just with first, second medium periphery surface is just to connection, described first, second medium periphery is respectively equipped with first on the surface, two inner groovies, this is first years old, two inner groovies respectively with bearing cap with the oil drain passage on bearing support just to being communicated with.

As further improvement of the utility model, the triangular structure of right angle of first and second inner groovy on first and second medium described respectively in symmetrical configuration, and this triangular structure of right angle is the radial vertical wall extended towards bearing one end.

As further improvement of the utility model, described ball screw one end is also bolted with first and second jam nut respectively, and this first and second jam nut is tight against the axial end that first and second medium deviates from mutually respectively.

As further improvement of the utility model, the lubricant oil oil inlet passage on described bearing cap is positioned at bearing (ball) cover lateral ends and is provided with fuel inlet fitting.

The beneficial effects of the utility model are: the utility model passes through first, second medium surface arranges first, two inner groovies, can first be accumulated in from the moisture entered between bearing support and medium and from the gap between bearing cap and medium, in the inner groovy of second medium periphery, can not continue inwardly to flow into Bearing inner, when lathe works, first, second medium High Rotation Speed, by its first, the moisture accumulated in two grooves throws away along oil drain passage fast, realize Quick drainage, this smart structural design, moisture can be avoided to enter bearing, extend bearing working life.
