Embodiment
Below in conjunction with the accompanying drawings, the embodiment of the present invention is described in detail, it is to be understood that the guarantor of the present invention
Shield scope is not limited by embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " comprising " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other members
Part or other parts.
As shown in Figure 4 and Figure 5, according to the drive mechanism of the split type bent axle additional gear of the specific embodiment of the invention
Concrete structure includes：Crankshaft-flywheel end 21, bell housing gear-box 22, oil sealing 23 and bent axle additional gear.Wherein, bent axle additional teeth
Take turns to be split type, including cushion block 24 and crankshaft toothed wheel 25, during installation, cushion block 24 is first mounted in crankshaft-flywheel end 21, refills and has pressed
The bell housing gear-box 22 of oil sealing 23 so that the Impact direction of oil sealing installation is consistent with its lip direction, then installs crank teeth
Wheel 25.Because oil sealing Impact direction is consistent with lip direction, oil seal lip will not flange；Installation quality is able to observe that simultaneously,
It is convenient to check installation situation, improve process control quality.
Specifically, bent axle is the main rotating mechanism of engine, is most important part in engine.It bears connecting rod
The power transmitted, and be transformed into torque and exported by bent axle and drive other annexes on engine to work.Bent axle is rotated
Centrifugal force, the gas inertia power of mechanical periodicity and the collective effect of reciprocal inertia force of quality, bent axle is set to bear flexion torsion load
The effect of lotus.Therefore it is required that bent axle has enough strength and stiffness, journal surface need are wear-resisting, work is uniform, balance is good.Bent axle
Flywheel end 21 stretches out shorter, cannot be introduced into the oil pocket of bell housing gear-box.Therefore crankshaft-flywheel end 21 is added by bent axle
Gear is driven idle gear and hydraulic pump gear as extra power output mouth.
Oil sealing 23 has along the axially extending seal lip of axis hole, and the sealing principle of oil sealing requires will direction when lip is installed
The oil pocket (oil pocket of bell housing gear-box) of required sealing, require that oil sealing must first be pressed into bell housing oil sealing peace in technique simultaneously
Fill on hole.Then body rear end face could be attached to as overall together with bell housing so that bent axle additional gear is formed with oil sealing
Sealing surface.
Bent axle additional gear is Split type structure, including cushion block 24 and crankshaft toothed wheel 25, cushion block 24 are annular shape, and center has
Crankshaft toothed wheel is perforated；Periphery is as oil sealing mounting surface, for forming sealing surface with oil sealing.The side of cushion block 24 is crankshaft-flywheel end
Mounting surface, and with spacing ring convex that are axially extending and being set with crankshaft-flywheel end periphery.The opposite side of cushion block 24 is crank teeth
Mounting surface is taken turns, and with the step positioning spigot that installation is adapted to crankshaft toothed wheel.The installation end of crankshaft toothed wheel 25 and cushion block 24 has
There is the step head being adapted to the step positioning spigot.As shown in figure 5, crankshaft toothed wheel 25 forms sealing trigonum with cushion block 24, should
Sealing trigonum is provided with O-ring 26 and sealed.
During installation, cushion block 24 is first mounted in crankshaft-flywheel end 21, refills the bell housing gear-box 22 for having pressed oil sealing 23 so that
The oil sealing mounting surface of cushion block 24 forms sealing surface, and the Impact direction of the now installation of oil sealing 23 and its lip direction one with oil sealing
Cause, then crankshaft toothed wheel 25 is installed.Because oil sealing Impact direction is consistent with lip direction, oil seal lip will not flange；Energy simultaneously
Enough it was observed that installation quality, convenient to check installation situation, process control quality is improved.
To sum up, the drive mechanism of the split type bent axle additional gear uses split type bent axle additional gear so that oil sealing is pacified
The Impact direction of dress is consistent with its lip direction, oil sealing flange when preventing from assembling；Installation quality, convenient inspection are able to observe that simultaneously
Installation situation is looked into, improves process control quality.
The description of the foregoing specific illustrative embodiment to the present invention is to illustrate and the purpose of illustration.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can be much changed
And change.The purpose of selecting and describing the exemplary embodiment is that explain that the certain principles of the present invention and its reality should
With so that those skilled in the art can realize and utilize the present invention a variety of exemplaries and
Various chooses and changes.The scope of the present invention is intended to be limited by claims and its equivalents.
