The main tooth oil enveloping structure of rear axle reductor assembly in optimum Working.
The technical solution of the utility model is：
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, it is characterised in that：It is equipped with drive bevel gear in the drive bevel gear below tapered roller bearing, tapered roller bearing
Equipped with bearing block, the initiative taper above bearing, tapered roller bearing is equipped with by catch in the drive bevel gear below bearing block
Steel bushing is housed, steel bushing lower end, which is welded, end cap, and end cap is connected with tapered roller bearing interference on gear, tapered roller bearing and end
By being provided with oil sealing by bearing block between lid.
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 utility model are：
The main tooth oil enveloping structure design of the rear axle reductor assembly is simple, and practicality is good, is made by the positioning of oil seal seat end face
With, change 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, with
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 consistent of rear position very well
Property, 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
For overall structure, instead of the Split type structure of original bearing, and the gear platform in the middle of original bearing is subtracted, thus optimized structure；
Bearing inner race is made up of the inner ring A and inner ring B that section is respectively L-type, and is brought into close contact connection between the two, has subtracted original axle
The center spacer held, adjusts clearance from there through two inner rings, reduces parts, both reduce production cost, simplifies again
Installation process.
