Description

A kind of automobile bearing that can regulate internal lubrication oil mass

Technical field

This utility model relates to mechanical design field, particularly relates to a kind of internal lubrication oil mass of can regulating Automobile bearing.

Background technology

Bearing is the important foundation part in vehicle transmission, and it have the title in " joint of automobile industry ", many For supporting tire rotational speed.Automobile bearing mainly has two effects: vibroshock energy when being to maintain Vehicular turn Rotate with wheel and keep the motility turned to；Two be the outer ring of pressure bearing be rubber, so Can keep between vehicle body with vibroshock soft is connected, and vibration is led to due to Uneven road when preventing running car Cross vibroshock and pass to vehicle body, affect riding comfort, although an automobile bearing simply finding, but it and The reliability of car load, safety and comfortableness suffer from important relation, in terms of reliability for, once Bearing damage will influence whether the traveling of car load, in terms of safety for, the installation site of bearing is very Important, once break down and will affect the safety of car load, in terms of comfortableness for, bearing not only and The steady operative relation of vehicle is great, and the bearing of those poor qualities, it is also easy to produce bigger noise. The lubrication of this outer bearing is the most critically important, needs to inject lubricating oil inside long time running rear bearing, if lubricating oil The Bearing inner then time cannot be injected into the biggest to damage of the bearing for a long time.

Utility model content

The purpose of this utility model is that provides one can regulate internal lubrication to solve the problems referred to above The automobile bearing of oil mass.

This utility model is achieved through the following technical solutions above-mentioned purpose:

A kind of automobile bearing that can regulate internal lubrication oil mass, including in spline, little needle bearing, bearing Circle, oil exit pipe, be provided with described spline, arrange outside described bearing inner race inside described bearing inner race State little needle bearing, outside described little needle bearing, be provided with bearing centre circle, arrange outside described bearing centre circle There is big needle bearing, outside described big needle bearing, be provided with bearing outer ring, arrange outside described bearing outer ring There are connecting plate, described connecting plate side to be provided with described oil exit pipe, described connecting plate is provided with bolt, institute State and on bolt, be provided with nut, inside described connecting plate, be provided with end cap.

In said structure, when, after bearing long time running, near described bearing inner race, lubricants capacity reduces, attached Nearly pressure reduces the most therewith, and now external lubrication oil will pass through the described oil exit pipe entrance on described bearing outer ring Described bearing centre circle, described big needle bearing, described little needle bearing and described bearing inner race is lubricated in bearing, Until bearing internal external pressure is equal.

In order to increase the service life of bearing further, described spline is embedded in inside described bearing inner race, institute State close-packed arrays outside bearing inner race and have described little needle bearing, be close to described outside described little needle bearing Bearing centre circle.

In order to increase the service life of bearing further, outside described bearing centre circle, close-packed arrays has described big rolling Needle bearing, is close to described bearing outer ring, is embedded in outside described bearing outer ring outside described big needle bearing Inside described connecting plate.

In order to increase the service life of bearing further, described oil exit pipe is embedded on described connecting plate outer surface, Described bolt is threadedly attached on described connecting plate, and described nut is threadedly attached on described bolt.

In order to increase the service life of bearing further, described end cap is fastenedly connected in described connection by screw Inside plate.

Have the beneficial effects that: Bearing inner and outside perfect lubrication can be ensured the moment, improve bearing service life.

Detailed description of the invention

The utility model is described in further detail below in conjunction with the accompanying drawings:

As Figure 1-Figure 2, a kind of automobile bearing that can regulate internal lubrication oil mass, including spline 2, Little needle bearing 3, bearing inner race 1, oil exit pipe 9, be provided with spline 2 inside bearing inner race 1, with transmission Axle is connected, and is provided with little needle bearing 3, is provided with in bearing outside little needle bearing 3 outside bearing inner race 1 Circle 4, is provided with big needle bearing 5, is provided with bearing outer ring outside big needle bearing 5 outside bearing centre circle 4 6, it is provided with connecting plate 7 outside bearing outer ring 6, is connected with standing part, fixing bearing, connecting plate 7 side Face is provided with oil exit pipe 9, enters the passage of Bearing inner for lubricating oil, connecting plate 7 is provided with bolt 8, It is provided with nut 10 on bolt 8, is used for fixing bearing, inside connecting plate 7, is provided with end cap 11, seal shaft Hold inside.

In said structure, when, after bearing long time running, near bearing inner race 1, lubricants capacity reduces, near Pressure reduces the most therewith, and the oil exit pipe 9 that now external lubrication oil will pass through on bearing outer ring 6 enters in bearing Lubrication bearing centre circle 4, big needle bearing 5, little needle bearing 3 and bearing inner race 1, until bearing internal external pressure Till power is equal.

In order to increase the service life of bearing further, spline 2 is embedded in inside bearing inner race 1, in bearing Outside circle 1, close-packed arrays has little needle bearing 3, is close to bearing centre circle 4, bearing outside little needle bearing 3 Outside centre circle 4, close-packed arrays has big needle bearing 5, is close to bearing outer ring 6, axle outside big needle bearing 5 Being embedded in inside connecting plate 7 outside bearing outer-ring 6, oil exit pipe 9 is embedded on connecting plate 7 outer surface, bolt 8 Being threadedly attached on connecting plate 7, nut 10 is threadedly attached on bolt 8, and end cap 11 passes through Screw is fastenedly connected inside connecting plate 7.

Of the present utility model ultimate principle, principal character and advantage have more than been shown and described.The skill of the industry Art personnel are it should be appreciated that this utility model is not restricted to the described embodiments, in above-described embodiment and description Describe simply illustrates principle of the present utility model, on the premise of without departing from this utility model spirit and scope, This utility model also has various changes and modifications, and these changes and improvements both fall within this claimed practicality In novel scope.This utility model claims scope and is defined by appending claims and effect thing thereof.
