Abstract

The utility model discloses a shell body of a main speed reducer, which comprises a driving bevel gear cavity, a cavity between a first bearing mounting position and a second bearing mounting position, an upper oil duct and a lower oil duct and is characterized in that an oil duct is formed on the cavity between the upper oil duct and the lower oil duct of the shell body of the main speed reducer, the left end of the oil duct is communicated with the driving bevel gear cavity, and the right end of the oil duct is communicated with the cavity between the first bearing mounting position and the second bearing mounting position; and the oil duct inclines towards the direction that is high on the left and low on the right. The shell body of the main speed reducer effectively improves the lubrication effect of a main speed reducer and greatly prolongs the service life of the main speed reducer through arranging a new oil duct.

Description

A kind of bevel housing
Technical field
The utility model belongs to main reducing gear, specifically, relates to a kind of bevel housing that is used for automotive transmission.
Background technique
Main reducing gear is the critical piece that reduces rotating speed in the automotive transmission, increases moment of torsion.At present, lubricated (as shown in Figure 1) of main reducing gear normally has oil duct 1 on the top of bevel housing, it is high right low to go up oil duct 1 left side, drive bevel gear is rotated the lubricant oil that drives in the drive bevel gear chamber 1 and is entered oil duct, and in the cavity 4 between the inflow clutch shaft bearing mounting point 3 and the second Bearing Installation position 5, driven wheel of differential and bearing are lubricated, have oil duct 6 down in the bottom of reducer shell, and the low right high dip in this time oil duct 6 left sides, lubricant oil flows back to drive bevel gear chamber 1 by following oil duct 6, circulation so repeatedly is to realize lubricating the retarder bearing.But the shortcoming of this bevel housing oil channel structure is lubricated insufficient to second bearing 5, causes the serious wear of bearing, and causes main reducing gear to reduce greatly working life.
The model utility content
The purpose of this utility model is to provide a kind of high lubricating effect, the bevel housing of long service life.
The technical solution of the utility model is as follows: a kind of bevel housing, comprise the cavity between the drive bevel gear cavity clutch shaft bearing mounting point and the second Bearing Installation position, last oil duct and following oil duct, its key is: have oil duct on the cavity between oil duct on the described bevel housing and the following oil duct, this oil duct left end communicates with the drive bevel gear chamber, cavity between the right-hand member clutch shaft bearing mounting point and the second Bearing Installation position communicates, and this oil duct is the high right low direction inclination in a left side.
Drive bevel gear is rotated, the lubricant oil that drives in the drive bevel gear chamber rises, lubricant oil is sent to oil duct and last oil duct, lubricant oil enters in the cavity between the clutch shaft bearing mounting point and the second Bearing Installation position by described two oil ducts, because by two oil duct oil-feeds, increased the amount of the lubricant oil in the cavity, it is better lubricated to make the clutch shaft bearing and second bearing, particularly second bearing obtain.Subsequently, lubricant oil flows back in the drive bevel gear chamber by following oil duct.
The position of the lower middle of described oil duct between last oil duct and following oil duct.This position both can guarantee many oil-feeds, can guarantee that again the lubricant oil in the cavity does not reflux.
Described oil duct is the high right low direction in a left side and tilts, and the angle a of the center line of the center line of oil duct and retarder cavity is 8-15 °.This tilt angle helps the processing of flowing of lubricant oil and oil duct.
Beneficial effect: the utility model has improved the lubrication effect of main reducing gear effectively by offering new oil duct, has prolonged the working life of main reducing gear greatly.
Description of drawings
Fig. 1 is the bevel housing structural representation before improving.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 is the left view of Fig. 2.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
A kind of bevel housing as Fig. 2, shown in Figure 3, comprises the cavity 4 between drive bevel gear cavity 1, clutch shaft bearing mounting point 3 and the second Bearing Installation position 5, is having oil duct 2 and following oil duct 6 on the housing.On the cavity of the lower middle between oil duct on the bevel housing 2 and the following oil duct 6, have oil duct 7, these oil duct 7 left ends communicate with drive bevel gear chamber 1, cavity 4 between the right-hand member clutch shaft bearing mounting point 3 and the second Bearing Installation position 5 communicates, and this oil duct 7 is the high right low direction in a left side and tilts, and tilt angle a is 8-15 °.
Drive bevel gear is rotated, the lubricant oil that drives in the drive bevel gear chamber 1 rises, lubricant oil is sent to oil duct 7 and last oil duct 2, lubricant oil enters in the cavity 4 between the clutch shaft bearing mounting point 3 and the second Bearing Installation position 5 by described two oil ducts, because by two oil duct oil-feeds, increased the amount of the lubricant oil in the cavity 4, it is lubricated more fully to make the clutch shaft bearing and second bearing, particularly second bearing obtain.Subsequently, lubricant oil flows back in the drive bevel gear chamber 1 by following oil duct 6.

Claims (3)

1. bevel housing, comprise the cavity (4) between drive bevel gear cavity (1), clutch shaft bearing mounting point (3) and the second Bearing Installation position (5), last oil duct (2) and following oil duct (6), it is characterized in that: on the cavity between oil duct on the described bevel housing (2) and the following oil duct (6), have oil duct (7), this oil duct (7) left end communicates with drive bevel gear chamber (1), cavity (4) between the right-hand member clutch shaft bearing mounting point (3) and the second Bearing Installation position (5) communicates, and this oil duct (7) is the high right low direction inclination in a left side.
2. a kind of bevel housing according to claim 1 is characterized in that: described oil duct (7) is positioned on the neutral position cavity on the lower side between oil duct (2) and the following oil duct (6).
3. a kind of bevel housing according to claim 1 is characterized in that: described oil duct (7) is the high right low direction in a left side and tilts, and the angle a of the center line of the center line of oil duct and retarder cavity is 8-15 °.
