Abstract
The utility model discloses a kind of loading machine drive axle differential spider lubricating arrangement, including differential mechanism or so shell, axle shaft gear, cross axle and bevel gear；Four axis of cross axle are equipped with the oil inlet and outlet vertically communicated, and clearance fit is mounted on equipped with bevel gear, four axle journals outsides in differential mechanism or so four cross shaft holes of shell on four axle journals；Bevel gear is equipped with lubrication hole, and the outside of bevel gear is equipped with bevel gear gasket；The cone tooth engagement of cone tooth and bevel gear on axle shaft gear, the axis on axle shaft gear are equipped with axle shaft gear gasket and in differential mechanism or so the holes of shell, and differential mechanism or so shell is locked by screw bolt and nut.The lubricating arrangement has the characteristics that easy to maintain, high lubricating effect, long product lifecycle, solves the problems, such as that part makes cross axle and bevel gear lack of lubrication mainly by lubrication of splashing, trunnion journal or bevel gear bore wear is caused to eventually lead to part breaking in the prior art.
Description
Technical field
The utility model is related to driving bridge for engineering machinery differential lubricating devices, particularly loading machine drive axle differential mechanism ten
Word axis lubricating arrangement.
Background technology
Differential mechanism is widely used in loading machine drive axle at present, mainly by left and right axle shaft gear, four bevel gears
And differential mechanism or so shell composition.When loading machine turning driving or on uneven road surface when driving, it is desirable that left and right wheels with difference turn
Speed rolls, that is, ensures that both sides driving wheel makees PURE ROLLING, to adapt to different road surfaces.In the prior art, cross axle, cone tooth
Wheel, axle shaft gear are all mounted in differential mechanism or so shell, and the inner hole sleeve of bevel gear is on the axle journal of cross axle, in axle shaft gear
It rotates under effect, the lubricating system of cross axle is：Differential mechanism or so shell parts are steeped in lubricating oil, the lubrication master of part
It is realized by splashing.It has a defect that：Since differential mechanism or so shell only has part bubble in lubricating oil so that cross axle and cone
Gear lubrication is insufficient, causes trunnion journal or bevel gear bore wear, finally makes part breaking.
Invention content
The purpose of the utility model is to overcome drawbacks described above, provide a kind of making and easy to maintain, high lubricating effect, product
The loading machine drive axle differential spider lubricating arrangement of service life length solves part in the prior art and is lubricated mainly by splashing
Make cross axle and bevel gear lack of lubrication, trunnion journal or bevel gear bore wear is caused to eventually lead to asking for part breaking
Topic.
In order to achieve the above object, the utility model loading machine drive axle differential spider lubricating arrangement includes a differential mechanism left side
Shell, axle shaft gear, cross axle, bevel gear and differential right casing；Four axis on the cross axle be equipped with vertically communicate into
Oilhole and oil outlet, clearance fit is installed on the outside of four axle journals of the cross axle equipped with bevel gear on four axle journals of cross axle
In differential mechanism left housing and four cross shaft holes of differential right casing；The bevel gear is equipped with lubrication hole, the outside of bevel gear
Equipped with bevel gear gasket；The cone tooth engagement of cone tooth and bevel gear on the axle shaft gear, the axis on axle shaft gear are equipped with half
Shaft gear gasket is simultaneously mounted in the hole of differential mechanism left housing and differential right casing, and differential mechanism left housing and differential right casing pass through bolt
And nut check.
The loading machine drive axle differential spider lubricating arrangement of above structure has following technical characterstic and advantageous effect：
1st, four axis on cross axle are equipped with fuel feed hole and oil outlet, and when differential assembly rotates, lubricating oil passes through
Fuel feed hole enters and is flowed out from oil outlet, and trunnion journal and bevel gear endoporus is made to obtain sufficient lubrication, solves the prior art
It is middle because lack of lubrication trunnion journal or bevel gear bore wear is caused finally to make part breaking the problem of.
2nd, bevel gear is equipped with lubrication hole, and the field of conjugate action of bevel gear and axle shaft gear is made also to obtain sufficient lubrication, is carried significantly
High product quality well ensures the reliability of product.
Description of the drawings
Fig. 1 is the utility model loading machine drive axle differential spider lubricating arrangement main cross section structure diagram.
Reference numeral：Differential mechanism left housing 1, axle shaft gear 2, axle shaft gear gasket 3, nut 4, bolt 5, cross axle 6, cone tooth
Take turns gasket 7, bevel gear 8, differential right casing 9, lubrication hole 10, oil outlet 11, fuel feed hole 12.
Specific embodiment
In the following with reference to the drawings and specific embodiments to the utility model loading machine drive axle differential spider lubricating arrangement
It is described in further detail.
The drive axle differential spider of the utility model loading machine shown in Fig. 1 lubricating arrangement includes differential mechanism left housing 1, semiaxis
Gear 2, cross axle 6, bevel gear 8 and differential right casing 9；Four axis on the cross axle 6 are equipped with the oil inlet vertically communicated
Hole 12 and oil outlet 11, when differential assembly rotates, lubricating oil is entered by fuel feed hole 12, is flowed out from oil outlet 11, is made ten
6 axle journal of word axis and 8 endoporus of bevel gear obtain sufficient lubrication；Clearance fit is equipped with bevel gear on four axle journals of the cross axle 6
8, which is equipped with lubrication hole 10, and bevel gear 8 and the field of conjugate action of axle shaft gear 2 is made to obtain sufficient lubrication；The bevel gear
8 outside is equipped with bevel gear gasket 7, and differential mechanism left housing 1 and differential right casing 9 are mounted on the outside of four axle journals of cross axle 6
In four cross shaft holes, the cone tooth engagement of cone tooth and bevel gear 8 on axle shaft gear 2, the axis on axle shaft gear 2 is equipped with semiaxis
Cog spacers 3 are simultaneously mounted in the hole of differential mechanism left housing 1 and differential right casing 9, and differential mechanism left housing 1 and differential right casing 9 pass through
Bolt 5 and nut 4 are locked.
During work, differential assembly rotation makes lubricating oil pass through fuel feed hole 12 and enters, flowed out from oil outlet 11, because of cross
Axis 6 is clearance fit with bevel gear 8, and 6 axle journal of cross axle and 8 endoporus of bevel gear is made to obtain sufficient lubrication；Due to being set on bevel gear 8
There is lubrication hole 10, the field of conjugate action of bevel gear 8 and axle shaft gear 2 is made to obtain sufficient lubrication, has well solved lack of lubrication in this way
It the problem of caused trunnion journal or bevel gear bore wear finally make part breaking, and vehicle can not work, greatly improves
Product quality well ensures the reliability of product.
The loading machine drive axle differential spider lubricating arrangement of above structure has been well solved caused by lack of lubrication
The problem of trunnion journal or bevel gear bore wear finally make part breaking, and vehicle can not work, substantially increase product
Quality well ensures the reliability of product.
