Abstract
Description
Technical field
This utility model relates to a kind of balance shaft apparatus, belongs to automotive engine applications, relates to a kind of novel band vibration damping The balance shaft apparatus of gear.
Background technology
The noise and vibration of automobile directly affects driver comfort, and the vibration of electromotor and noise are mainly shaking of automobile Dynamic one of source and noise source.The vibration of electromotor can be reduced by assembling balance shaft apparatus.
Balance axle is by gear drive and to produce rotation so that it is the unbalanced turning moment that the balancing weight at two ends produces It is balanced with the reciprocal inertia force square of engine crank-connecting rod structure, thus reduces the vibration of system and the mesh of noise , increase the driver comfort of passenger car.Driving gear interference is fitted on bent axle and is considered as being rigidly connected with bent axle, driven gear It is positioned at the side of balance axle.When engine movements, owing to the difference duration of ignition of each cylinder causes bent axle to produce torsion alternately Rotational oscillation moves and is transferred to other parts of driven gear and balance shaft system, aggravates the vibration of these parts causing and coordinates with it The abrasion of movement parts, increase fit clearance and also produce new vibration and noise, reduce the durability of system.
A kind of balance shaft of engine is disclosed, on balance axle in Chinese utility model patent description CN201818708 Being provided with driven gear, this driven gear includes outer ring gear and inner ring wheel disc, and outer ring gear is assemblied on inner ring wheel disc, outward Be that structure is assembled in the gap of similar spline between circle gear and inner ring wheel disc, outside the adjacent key tooth of figure gear and interior figure wheel disc it Between be provided with block rubber, in order to being helical teeth with the balance tooth that engages of axle driving gear on the gear of outer ring.Use this utility model Technical scheme, although can reduce the vibration of electromotor, reduces the meshing noise between balance axle main driven gear, but this is driven Gear structure is complicated, needs the inner ring to gear to process the fit structure of similar spline respectively with outer ring, is therefore unfavorable for advising greatly Automatization's processing and manufacturing of mould, meanwhile, the balance axle of this utility model does not the most disclose the structure of balancing weight, it is impossible to effectively Ensure the durability of balance shaft system.
Summary of the invention
The defect existed for above-mentioned prior art, the technical problems to be solved in the utility model is to provide a kind of Novel belt The balance shaft apparatus of vibration-reduction gear, it is on the premise of the product function of satisfied balance axle, by vibration-reduction gear isolation bent axle Twisting vibration, promotes the durability of balance shaft system, can reduce the gearing noise of gear simultaneously, promotes the driving comfort of passenger car Property.
For solving above-mentioned technical problem, this utility model have employed the balance axle dress of such a Novel belt vibration-reduction gear Putting, it includes balancing axle；The two ends of described balance axle are provided with counterweight block；It is characterized in that: affixed on described balance axle There is vibration-reduction gear；Described vibration-reduction gear includes gear ring, rubber and wheel hub；Described rubber be arranged at described gear ring and described wheel hub it Between.
In a kind of preferred embodiment of the present utility model, described counterweight block includes flywheel side balancing weight and timing Side balancing weight；The center of gravity of described flywheel side balancing weight and the center of gravity of described timing side balancing weight are 180 ° of distributions.
In a kind of preferred embodiment of the present utility model, described timing side balancing weight be fixed on described balance axle and It is positioned at homonymy with described vibration-reduction gear.
In a kind of preferred embodiment of the present utility model, described vibration-reduction gear is provided with multiple lightening hole.
In a kind of preferred embodiment of the present utility model, the rolling friction position of described balance axle is provided with lining Set.
In a kind of preferred embodiment of the present utility model, described lining is connected with described balance axle interference fit.
In a kind of preferred embodiment of the present utility model, described rubber is hydrogenated butyronitrile.
In a kind of preferred embodiment of the present utility model, described vibration-reduction gear engages biography with the crankshaft toothed wheel on bent axle Dynamic.
In a kind of preferred embodiment of the present utility model, described rubber by vulcanizing treatment be fixed in described gear ring with Between described wheel hub.
The beneficial effects of the utility model are: this utility model simple in construction, manufacture easy to use, by using vibration damping tooth The twisting vibration of wheel isolation bent axle, simultaneously effective reduces the gearing noise of gear, and the lining of high rigidity increases rolling friction The wearability at position, promotes the durability of balance shaft system.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain this Utility model, is not used to limit this utility model.
The technical solution of the utility model is to assemble highdensity balancing weight at the two ends of balance axle, in balance axle assembling rolling Dynamic bearing position press-fits the lining of high rigidity and promotes wearability, and two ends balancing weight is fastened by bolts.Driving gear and driven tooth Having repeated hole to reduce gear weight on wheel, driven gear is made up of gear ring, wheel hub and rubber, and the metal part of two gears is by powder The metallurgy sintered molding in end.
The structural representation of the balance shaft apparatus of a kind of Novel belt vibration-reduction gear as shown in Figure 1 understands, this utility model The balance shaft apparatus of a kind of Novel belt vibration-reduction gear includes balancing axle 2；The two ends of balance axle 2 are connected with counterweight by bolt Block；It is connected with vibration-reduction gear 3 on balance axle 2；Vibration-reduction gear 3 includes gear ring 301, rubber 302 and wheel hub 303；Rubber 302 is arranged Between gear ring 301 and wheel hub 303；Gear ring 301 and wheel hub 303 are linked together shape by rubber 302 by vulcanizing treatment technique Become an integral vibration damping gear.Wherein, counterweight block includes flywheel side balancing weight 1 and timing side balancing weight 5；Flywheel side counterweight The center of gravity of block 1 and the center of gravity of timing side balancing weight 5 are 180 ° of distributions.Timing side balancing weight 5 be fixed on described balance axle 2 and with Vibration-reduction gear 3 is positioned at homonymy.Crankshaft toothed wheel 4 interference is fitted on bent axle, and lining 6 interference is fitted in the rolling friction of balance axle 2 Position.Rubber 302 is HNBR (hydrogenated butyronitrile).
It should be appreciated that the above, the only detailed description of the invention of the present invention, but protection scope of the present invention is not Be confined to this, any those of ordinary skill in the art in the technical scope that disclosed herein, the change that can readily occur in Or replace, all should contain within protection scope of the present invention.
