The invention discloses a kind of combined balance shaft gear is combined by coaxial master gear and pinion, be respectively arranged with the position groove opposite on described master gear and the pinion, be equipped with in the cavity that two grooves form and be parallel to the elastic element that gear face is placed, master gear is relative with the teeth on the pinion during stack mounting misplaces, its magnitude of misalignment is greater than the back lash of gear pair, after the gear pair engagement was installed, the teeth of the adjacent dislocation of balance shaft gear contacted the left and right sides of same engagement teeth groove respectively; When trunnion shaft actuation gear and balance shaft gear are intermeshing, master gear and pinion are under the active force of elastic element, effectively eliminated the back lash between trunnion shaft actuation gear and the balance shaft gear, make that the engagement between gear is more smooth and easy, reduced the knocking noise that produces in the operation process, this product also is widely used in being on the gear driving pair of variable working condition.
Description
Technical field
The present invention relates to the gear driving pair of variable working condition, particularly a kind of balance shaft gear that is applied in the trunnion shaft motorcycle engine.
Background technique
Because the piston and the connecting rod of present motorcycle engine can produce powerful inertial force when high speed rotating, and this inertial force can pass to vehicle frame by motorcycle engine, thereby cause motorcycle vibration, can cause noise simultaneously, energy consumption, coupling is loosening, influences such as overload, thereby the life-span and the reliability of motorcycle engine have been lowered greatly, in order to alleviate the vibration of motor, the present common use trunnion shaft of people motorcycle engine, its principle is by increase suitable counterweight on the bent axle that the trunnion shaft actuation gear is installed, caused vibration when alleviating the bent axle high speed rotating, but owing to what transmit between trunnion shaft actuation gear and the balance shaft gear is the alternation active force, and when being meshing with each other, it exists the back lash, thereby cause producing knocking noise in the operation process, thereby be difficult to meet people's usage requirement.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of a kind of combined balance shaft gear that can reduce the knocking noise that trunnion shaft actuation gear and balance shaft gear produce in the operation process.
The technical solution adopted in the present invention is:
A kind of combined balance shaft gear is combined by coaxial master gear and pinion, be respectively arranged with the position groove opposite on described master gear and the pinion, be equipped with in the cavity that two grooves form and be parallel to the elastic element that gear face is placed, master gear is relative with the teeth on the pinion during stack mounting misplaces, its magnitude of misalignment is greater than the back lash of gear pair, after the gear pair engagement was installed, the teeth of the adjacent dislocation of balance shaft gear contacted the left and right sides of same engagement teeth groove respectively.
As improvement of the technical scheme, described groove is two or more, and evenly distributes around Gear center; Respectively be provided with through hole on described master gear and the pinion, the side-play amount that the back two through hole is installed is identical with the magnitude of misalignment of teeth;
As further improvement in the technical proposal, described pinion cross-under is provided with spring washer on the end face of pinion on master gear, and spring washer top is provided with the back-up ring that is fastened on the master gear; The flute profile of described master gear and pinion, the number of teeth, modulus are identical; Described elastic element is a spring.
The invention has the beneficial effects as follows: because balance shaft gear is combined by master gear and pinion mutual dislocation, and be provided with between master gear and the pinion and be parallel to the elastic element that gear face is placed, when trunnion shaft actuation gear and balance shaft gear are intermeshing, master gear and pinion are under the active force of elastic element, effectively eliminated the back lash between trunnion shaft actuation gear and the balance shaft gear, make that the engagement between gear is more smooth and easy, reduced the knocking noise that produces in the operation process, this product also is widely used in being on the gear driving pair of variable working condition.

Embodiment
With reference to Fig. 1, Fig. 4, Fig. 5, a kind of combined balance shaft gear is combined by coaxial master gear 1 and pinion 2, its stack mounting mode is: at first with pinion 2 cross-under on master gear 1, and spring washer 5 is set on the end face of pinion 2, spring washer 5 tops are provided with the back-up ring 4 that is fastened on the master gear 1, certainly when practical operation, master gear 1 can also use other common mechanical type to carry out stack mounting with pinion 2.
With reference to Fig. 2, Fig. 3, be respectively arranged with position groove opposite 11,21 on master gear 1 of the present invention and the pinion 2, groove 11 relative pinion 2 upper grooves 21 on the gear 1 turn an angle around gear 1 center, and in the cavity that two grooves 11,21 form the elastic element 3 that is parallel to the gear face placement is installed, elastic element 3 can be helical spring, belleville spring, torsion spring and rubber etc.; The design make to install relative dislocation of teeth on back master gear 1 and the pinion 2, and its magnitude of misalignment is greater than the back lash of gear pair, and after the gear pair engagement installation, the teeth of the adjacent dislocation of balance shaft gear contact the left and right sides of same engagement teeth groove respectively.Stressed evenly in order to make that pinion 2 is installed the back, described groove 11,21 can be set to two or morely, and evenly distribute around Gear center; In addition; flute profile, the number of teeth, the modulus of described master gear 1 and pinion 2 are identical; this design makes that the engagement between the teeth is more smooth and easy; but in the practical operation; the flute profile of master gear 1 and pinion 2, the number of teeth, modulus can be different; as long as after the gear pair engagement is installed; the left and right sides that the teeth of the adjacent dislocation of balance shaft gear contact same engagement teeth groove respectively gets final product; therefore as long as it reaches technique effect of the present invention with essentially identical means, all should belong to protection scope of the present invention.
This product is more convenient in order to install with trunnion shaft actuation gear 6 engagement, on master gear 1 and pinion 2, respectively be provided with through hole 12,22, back two through hole 12 is installed, 22 side-play amount is identical with the magnitude of misalignment of teeth, during installation, at first use bearing pin to pass through hole 12,22, thereby pressure spring 3, make master gear 1 overlap fully with teeth on the pinion 2, then balance shaft gear is engaged on the trunnion shaft actuation gear 6, at last bearing pin is extracted and got final product, at this moment, master gear 1 and pinion 2 are under the active force of elastic element 3, effectively eliminated the back lash between trunnion shaft actuation gear 6 and the balance shaft gear, make that the engagement between gear is more smooth and easy, reduced the knocking noise that produces in the operation process, this product also is widely used in being on the gear driving pair of variable working condition, as: the camshaft gear wheel of motorcycle engine etc.
