Abstract
The invention discloses a kind of heavy intermediate beads of integrated bearing inner race, it mainly include intermediate support, intermediate bead, locking nut, middle spline shaft, intermediate support bearing, intermediate support bearing is integrated in the outer circle of the intermediate bead, intermediate support bearing is mounted on intermediate support, intermediate support and intermediate bead is set to be assembled into an assembly, the intermediate bead of integrated intermediate support is mounted on middle spline shaft, and locking nut locks middle spline shaft and realizes positioning.Intermediate support is integrated into intermediate bead by the present invention, and bearing inner race is processed into alley with intermediate bead outer round surface and is replaced, number of parts can be effectively reduced, the accumulated error after reducing assembly, transmission shaft, which is reduced by three components to need to only fill two components, can be completed assembly, improve the assembly efficiency of driving-shaft assembly, middle spline shaft length is reduced, driving-shaft assembly weight is reduced, reduces transmission shaft rotary inertia, transmission shaft performance is improved, starting oil consumption is reduced.
Description
Technical field
The present invention relates to the fields of truck drive shaft, and in particular to a kind of heavy intermediate bead of integrated bearing inner race.
Background technique
Existing driving-shaft assembly assembling structure is as follows: intermediate support is provided with the bearing with bearing Internal and external cycle, bearing band
Bracket is installed along on middle spline shaft, is compressed on bearing to middle spline shaft with intermediate bead, then locked with locking nut
Realize bearing positioning.
Such structure has the following deficiencies: that middle spline shaft length is too long, and the material of consumption is more；Driving-shaft assembly weight
It is heavier；The rotary inertia of driving-shaft assembly is big；Each element precision requires height, and it is big that there are accumulated errors after assembly；Driving-shaft assembly
Assembling link is more, and assembly time is long.
Summary of the invention
It is an object of the invention to overcome the shortcomings of the prior art, and provide in a kind of heavy type of integrated bearing inner race
Between flange.
The object of the present invention is achieved by the following technical solutions: the heavy type of this integrated bearing inner race is intermediate prominent
Edge, mainly include intermediate support, intermediate bead, locking nut, middle spline shaft, intermediate support bearing, the intermediate bead
Intermediate support bearing is integrated in outer circle, intermediate support bearing is mounted on intermediate support, fills intermediate support and intermediate bead
It is made into an assembly, the intermediate bead of integrated intermediate support is mounted on middle spline shaft, and locking nut locks middle spline shaft
Realize positioning.
Further, the alley as bearing inner race is provided in the outer circle of the intermediate bead.
The invention has the benefit that
1, ball outlet channel is directly processed in intermediate bead outer circle as bearing inner race, is reduced number of parts, is simplified structure；
2, bearing is not installed on middle spline shaft, shortens the length of middle spline shaft, reduce supplies consumption；
3, the rotary inertia of driving-shaft assembly is reduced, oil consumption when starting is reduced；
4, reduce Assembly part, to reduce the accumulated error after assembly；
5, drive shaft cartridge timing original need to fill and only need to fill two components after three components change assembly can be completed, and improve transmission
The assembly efficiency of axle assembly.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Description of symbols: intermediate support 1, intermediate bead 2, locking nut 3, middle spline shaft 4, intermediate support bearing 5.
Specific embodiment
Below in conjunction with attached drawing, the present invention will be described in detail:
Embodiment: as shown in the picture, the heavy intermediate bead of this integrated bearing inner race, mainly include intermediate support 1, in
Between flange 2, locking nut 3, middle spline shaft 4, intermediate support bearing 5, be integrated with intermediate branch in the outer circle of the intermediate bead 2
Frame bearing 5, intermediate support bearing 5 are mounted on intermediate support 1, and intermediate support 1 and intermediate bead 2 is made to be assembled into an assembly,
Assembly part quantity is reduced, to reduce the accumulated error after assembly, while three components need to be filled with middle script in drive shaft cartridge
Only need to fill two components can be completed assembly now, improve the assembly efficiency of driving-shaft assembly；The centre of integrated intermediate support 1
Flange 2 is mounted on middle spline shaft 4, and middle spline shaft 4 can cancel the bearing guard of axle bearing mount portion position, reduces intermediate flower
Key axis 4 processes bearing guard high-precision requirement, while can shorten the length of middle spline shaft 4；Locking nut 3 locks intermediate spline
Axis 4 realizes positioning.
It is provided with the alley as bearing inner race in 2 outer circle of intermediate bead, can reach and reduce setting for a bearing inner race
Count purpose.
Intermediate support is integrated into intermediate bead by the present invention, and bearing inner race intermediate bead outer round surface is processed ball
Road replaces, it is possible to reduce number of parts reduces middle spline shaft length, saves middle spline shaft material, reduces driving-shaft assembly
Weight reduces transmission shaft rotary inertia, improves transmission shaft performance, reduces oil consumption when starting.Assembly part is decreased simultaneously
Quantity, to reduce the accumulated error after assembly, drive shaft cartridge is with need to fill three components need to only fill two components i.e. now originally
Achievable assembly improves the assembly efficiency of driving-shaft assembly.The present invention practical application in heavy duty transmission axle assembly product.
It is understood that it will be understood by those skilled in the art that being subject to technical solution of the present invention and inventive concept
It all should fall within the scope of protection of the appended claims of the present invention with replacement or change.
