Detailed description of the invention
Below in conjunction with the accompanying drawings, detailed description of the invention of the present utility model is described in detail, but it should reason
Solve protection domain of the present utility model not limited by detailed description of the invention.
Explicitly indicate that unless otherwise other, otherwise in entire disclosure and claims, term " bag
Include " or its conversion as " comprising " or " including " etc. will be understood to comprise stated element or
Ingredient, and do not get rid of other element or other ingredient.
As shown in Figure 4 and Figure 5, according to the split type bent axle additional teeth of this utility model detailed description of the invention
The concrete structure of the drive mechanism of wheel includes: crankshaft-flywheel end 21, bell housing gear-box 22, oil sealing 23
With bent axle additional gear.Wherein, bent axle additional gear is split type, including cushion block 24 and crankshaft toothed wheel 25,
During installation, cushion block 24 is first contained in crankshaft-flywheel end 21, refills the bell housing gear-box pressing oil sealing 23
22 so that the Impact direction that oil sealing is installed is consistent with its lip direction, then crankshaft toothed wheel 25 is installed.By
Consistent with lip direction in oil sealing Impact direction, oil seal lip will not flange；It is able to observe that installation simultaneously
Quality, the convenient installation situation that checks, raising process control quality.
Specifically, bent axle is the main rotating mechanism of electromotor, is most important parts in electromotor.It
Bear the power that connecting rod transmits, and be transformed into torque and exported by bent axle and drive on electromotor other attached
Part works.Bent axle is by the centrifugal force of gyrating mass, the gas inertia power of mechanical periodicity and reciprocal inertia force
Common effect, make bent axle bear the effect of flexion torsion load.Therefore it is required that bent axle has enough intensity
And rigidity, journal surface need are wear-resisting, work is uniform, balance is good.Crankshaft-flywheel end 21 stretches out shorter,
Cannot be introduced in the oil pocket of bell housing gear-box.Therefore crankshaft-flywheel end 21 is come by bent axle additional gear
Transmission idle gear and hydraulic pump gear are as extra power delivery outlet.
Oil sealing 23 has along the axially extended seal lip of axis hole, and the sealing principle of oil sealing requires that lip is installed
Time to require in technique that oil sealing must towards the oil pocket (oil pocket of bell housing gear-box) of required sealing simultaneously
Must first be pressed in bell housing seal mounting hole.Then after could installing to body as entirety together with bell housing
End face so that bent axle additional gear forms sealing surface with oil sealing.
Bent axle additional gear is Split type structure, and including cushion block 24 and crankshaft toothed wheel 25, cushion block 24 is annulus
Shape, central authorities have crankshaft toothed wheel perforation；Periphery is as oil sealing installed surface, for forming sealing surface with oil sealing.
The side of cushion block 24 is crankshaft-flywheel end installed surface, and has axially extending and overlap with crankshaft-flywheel end periphery
The spacing ring of dress is convex.The opposite side of cushion block 24 is crankshaft toothed wheel installed surface, and has adaptive with crankshaft toothed wheel
The step positioning spigot installed.Crankshaft toothed wheel 25 with this step location only has with the installation end of cushion block 24
The step head that mouth is adaptive.As it is shown in figure 5, crankshaft toothed wheel 25 is formed with cushion block 24 seals trigonum, should
Sealing trigonum is provided with O 26 and seals.
During installation, cushion block 24 is first contained in crankshaft-flywheel end 21, refills the bell housing tooth pressing oil sealing 23
Roller box 22 so that the oil sealing installed surface of cushion block 24 forms sealing surface with oil sealing, and now oil sealing 23 is installed
Impact direction consistent with its lip direction, then install crankshaft toothed wheel 25.Due to oil sealing Impact direction with
Lip direction is consistent, and oil seal lip will not flange；It is able to observe that installation quality, convenient inspection are pacified simultaneously
Dress situation, improves process control quality.
To sum up, the drive mechanism of this split type bent axle additional gear uses split type bent axle additional gear, makes
The Impact direction obtaining oil sealing installation is consistent with its lip direction, oil sealing flange when preventing from assembling；Simultaneously can
Observe installation quality, the convenient installation situation that checks, raising process control quality.
The aforementioned description to specific illustrative embodiment of the present utility model illustrates that and the mesh of illustration
's.These describe and are not wishing to be defined to this utility model disclosed precise forms, and it will be apparent that
According to above-mentioned teaching, can much change and change.Exemplary embodiment is selected and describes
Purpose be to explain certain principles of the present utility model and actual application thereof, so that the skill of this area
Art personnel be capable of and utilize various different exemplary of the present utility model and various not
Same selection and change.Scope of the present utility model is intended to be limited by claims and equivalents thereof.
