Abstract
The utility model discloses a kind of output axle assembly of fixed axle gearbox, belong to engineering machinery field.It includes preceding output flange, rear end cap, casing, output shaft, rear output flange and output shaft gear, the output shaft gear is located on output shaft, the preceding output flange and the rear output flange are separately fixed at the two ends of output shaft, angular contact ball bearing of the output shaft provided with support output shaft gear.Integrally anti-dynamic load impact ability is more preferable for the utility model output axle assembly, and sealing reliability is higher, and comprehensive use cost is lower.
Description
Technical field
The utility model belongs to a kind of engineering machinery accessory, specifically, more particularly to a kind of fixed axle gearbox is defeated
Go out axle assembly.
Background technology
At present, domestic 3 tons of loading machine speed changers, use fixed shaft type dynamic power shift gear box and single turbine hydraulic moment changeable mostly
Device, the moment of torsion of torque-converters output is delivered to transmission input shaft through power transmission shaft, and drive axle is delivered to through output shaft of gear-box, drives
Wheel realizes that complete machine is travelled.Because loading machine working condition is more severe, vibration, shock loading during overall operation can reduce change
The reliability of fast case output flange and propeller shaft couplings, causes to export the bearing damage of axle assembly, output shaft abrasion and oil sealing leakage
The failures such as oil, make complete machine can not normal work, the use demand of influence user.
Utility model content
The utility model purpose is to provide a kind of output axle assembly of fixed axle gearbox, to overcome complete machine in the prior art
Vibration, shock loading during operation can reduce the reliability of gearbox output flange and propeller shaft couplings, cause complete machine can not be just
The defect often worked.
The utility model is realized using following technical scheme：A kind of output axle assembly of fixed axle gearbox, including
Preceding output flange, rear end cap, casing, output shaft, output shaft gear and rear output flange, the output shaft gear are located at output shaft
On, the preceding output flange and the rear output flange are separately fixed at the two ends of output shaft, and the output shaft is provided with support
The angular contact ball bearing of output shaft gear.
The preceding output flange and the rear output flange are fixed on the two of output shaft by bolt and lock washer respectively
End.
Viton seal ring and nitrile rubber sealing ring are used between the preceding output flange, rear output flange and rear end cap
Double seal ring structure.
The preceding output flange, rear output flange are provided with ledge structure.
Sealed between the rear end cap and casing using O-ring.
Compared with prior art, the beneficial effects of the utility model are：The utility model exports axle assembly integrally anti-dynamic load
More preferably, sealing reliability is higher for lotus impact capacity, and comprehensive use cost is lower.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of output axle assembly of fixed axle gearbox, including preceding output flange 1, rear end cap 2, casing 3,
Output shaft 5, output shaft gear 6 and rear output flange 7, the output shaft gear 6 are located on output shaft 5, the preceding output flange 1
The two ends of output shaft 5, angle of the output shaft 5 provided with support output shaft gear 6 are separately fixed at the rear output flange 7
Contact ball bearing 4, angular contact ball bearing 4 possesses the ability for bearing axial force, improves the reliability of output shaft 5.
Preceding output flange 1 and rear output flange 7 are locked in output using two lock washers and 10.9 grade bolts 10 respectively
The two ends of axle 5, locking reliability is high, and part universality is good.
Viton seal ring 8 and nitrile rubber sealing ring are used between preceding output flange 1, rear output flange 7 and rear end cap 2
9 Double seal ring structures, improve sealing reliability, reduce cost.Wherein viton seal ring 8 mainly plays oil sealing, butyronitrile rubber
9 dustproof effects of glue sealing ring.
As shown in Fig. 2 being sealed between rear end cap 2 and casing 3 using O-ring 11, this structure batch on loading machine drive axle
Using reliability is high, and has the advantages that simple in construction, cost is low compared to sealing gasket sealing.
As shown in figure 3, preceding output flange 1, the structure of rear output flange 7 are consistent, and provided with ledge structure 12, ledge structure
12 are used to rotate when preventing bolt 10 from assembling, and improve the convenience that flange is assembled with bolt 10, part universality is good.
