Abstract
The present invention relates to a kind of oil enveloping structure, and in particular to a kind of main tooth oil enveloping structure of rear axle reductor assembly.Including drive bevel gear, tapered roller bearing, oil sealing, end cap and steel bushing, steel bushing is housed on the semiaxis above half-conical roller bearing, steel bushing lower end, which is welded, end cap, and end cap is connected with tapered roller bearing interference, by being provided with oil sealing by oil seal seat between tapered roller bearing and end cap.The oil enveloping structure designs simple, and practicality is good, by the positioning action of oil seal seat end face, changes the mounting means of traditional oil enveloping structure, so that the shift phenomenon being also easy to produce during existing oil seal pressing is avoided, and because of the bounce-back of itself rigidity generation after oil seal pressing.The oil enveloping structure can ensure that oil sealing batch press-fits the uniformity of rear position very well, and increase sealing surface, oil sealing is in optimum Working all the time.
Description
Technical field
The present invention relates to a kind of oil enveloping structure, and in particular to a kind of main tooth oil enveloping structure of rear axle reductor assembly.
Background technology
Rear axle reductor assembly is one of important component of automobile axle, the main tooth of traditional rear axle reductor assembly（Actively
Bevel gear）Oil sealing, due to its structure and the mounting means reason of oil sealing, causes it to be also easy to produce skew, and because certainly after oil seal pressing
The bounce-back that body is rigidly produced, easily causes oil leak, according to statistics, in back axle failure mode, because of asking that main tooth oil sealing oil leak is produced
Topic is especially prominent, therefore, it is necessary to improve it, so as to be in optimum Working all the time after the completion of oil sealing assembling.
The content of the invention
It is an object of the invention to：There is provided a kind of simple in construction, practicality good, oil sealing can be made to be in all the time after the completion of assembling
The main tooth oil enveloping structure of rear axle reductor assembly of optimum Working.
The technical scheme is that：
A kind of main tooth oil enveloping structure of rear axle reductor assembly, including drive bevel gear, tapered roller bearing, oil sealing, end cap and steel
Set, it is characterised in that：It is equipped with the drive bevel gear below tapered roller bearing, tapered roller bearing and is equipped with drive bevel gear
The drive bevel gear above bearing, tapered roller bearing is equipped with by catch in drive bevel gear below bearing block, bearing block
Upper that steel bushing is housed, steel bushing lower end, which is welded, end cap, and end cap is connected with tapered roller bearing interference, tapered roller bearing and end cap it
Between by being provided with oil sealing by bearing block.
Described tapered roller bearing is made up of bearing block, bearing inner race, bearing outer ring, roller and retainer, bearing block
Bearing inner race and bearing outer ring are inside installed, pyramid type is provided with by retainer symmetry shape between bearing inner race and bearing outer ring
Roller；Bearing block oil filler point and pilot hole are provided with described bearing block；It is provided with bearing outer ring and bearing block oiling
The corresponding outer ring oil filler point in hole.
Described bearing outer ring section is tapered.
Described bearing inner race is split type, and bearing inner race is made up of inner ring A and inner ring B, inner ring A and inner ring B section
Respectively L-type, is brought into close contact connection between inner ring A and inner ring B.
The beneficial effects of the present invention are：
The main tooth oil enveloping structure design of the rear axle reductor assembly is simple, and practicality is good, by the positioning action of oil seal seat end face, changes
Become the mounting means of traditional oil enveloping structure, so that the shift phenomenon being also easy to produce during existing oil seal pressing is avoided, and oil
Envelope press-fits the bounce-back rigidly produced by itself afterwards.The oil enveloping structure can ensure that oil sealing batch press-fits the uniformity of rear position very well,
And increase sealing surface, oil sealing is in optimum Working all the time, while the outer ring of the tapered roller bearing of the oil enveloping structure is
Overall structure, instead of the Split type structure of original bearing, and has subtracted the gear platform in the middle of original bearing, has thus optimized structure；Axle
Hold inner ring to be made up of the inner ring A and inner ring B that section is respectively L-type, and be brought into close contact connection between the two, subtract original bearing
Center spacer, adjust clearance from there through two inner rings, reduce parts, both reduce production cost, again simplify peace
Dress process.

Embodiment
The main tooth oil enveloping structure of the rear axle reductor assembly includes drive bevel gear 1, tapered roller bearing 2, oil sealing 3, end cap 4
With steel bushing 5, tapered roller bearing 2 is housed in drive bevel gear 1.Tapered roller bearing 2 is outside bearing block 6, bearing inner race, bearing
Circle 8, roller 9 and retainer 7 are constituted, and bearing inner race and bearing outer ring 8, bearing inner race and bearing outer ring 8 are provided with bearing block 6
Between conical roller 9 is provided with by the symmetry shape of retainer 7；Bearing block oil filler point 10 and assembling are provided with bearing block 6
Hole 11；Outer ring corresponding with bearing block oil filler point 10 oil filler point 12 is provided with bearing outer ring 8.
The section of bearing outer ring 8 of tapered roller bearing 2 is tapered.Bearing inner race is split type, and bearing inner race is by inner ring A13
Constituted with inner ring B14, inner ring A13 and inner ring B14 section are respectively L-type, the company of being brought into close contact between inner ring A13 and inner ring B14
Connect.The bearing outer ring 8 of the oil enveloping structure tapered roller bearing 2 is overall structure, instead of the Split type structure of original bearing, and subtract
