In one embodiment, the length when length of groove can be less than spring nature.
In one embodiment, the logarithm of groove can be determined according to the size of pretightening force needed for gear mechanism.
In one embodiment, the logarithm of groove can be 2 to or 3 right.
According to one side of the present disclosure, a kind of gear mechanism manufacture method is provided, comprise: manufacture master gear and pinion, make master gear identical with the tooth of pinion, the center of master gear is with stationary axle, and the center of pinion is hole, pinion can rotate around the stationary axle of master gear, the side fitted of master gear and pinion is provided with at least one pair of groove, when at least one pair of groove is between two in the face of overlapping, there is angular displacement between master gear and the corresponding teeth of pinion; And assemble master gear and pinion, at least one pair of groove, spring is set respectively.
Solved a difficult problem for stuck fault and unnecessary clearance in gear transmission by simple and mechanical mechanism according to gear mechanism of the present disclosure, structure is simple, takes up room little, reliable and stable work.
Accompanying drawing explanation
With reference to below in conjunction with the explanation of accompanying drawing to disclosure embodiment, above and other objects, features and advantages of the present disclosure can be understood more easily.In the accompanying drawings, the identical or corresponding reference character of employing represents by the technical characteristics of identical or correspondence or parts.
Fig. 1 is according to the assembling schematic diagram of gear mechanism of the present disclosure under initial mounting state.
Fig. 2 is according to the assembling schematic diagram of gear mechanism of the present disclosure under operation mode.
Fig. 3 is the part schematic diagram according to gear mechanism of the present disclosure.
Fig. 4 is the flow chart of the manufacture method according to gear mechanism of the present disclosure.
Embodiment
Be described in detail according to the structure of gear mechanism of the present disclosure and assembly relation below in conjunction with accompanying drawing 1 to 3.Fig. 1 and Fig. 2 illustrates respectively according to the assembling schematic diagram of gear mechanism of the present disclosure under initial mounting state and operation mode.Fig. 3 is the part schematic diagram according to gear mechanism of the present disclosure.
Master gear 1 and pinion 2 is comprised according to the gear mechanism of disclosure embodiment.Can clearly be seen that from Fig. 2, master gear 1 is identical with the tooth of pinion 2.And as being clearly shown that in Fig. 3, the center of master gear 1 is with stationary axle, and the center of pinion 2 is hole.See Fig. 1 and Fig. 2, pinion 2 can rotate around the stationary axle of master gear 1.Can find out from three width figure, the side fitted of master gear 1 and pinion 2 is provided with at least one pair of groove.The effect of this at least one pair of groove is: the spring can received for the formation of pretightening force in they space content formed toward each other.In one alternate embodiment, the logarithm of groove can be determined according to the size of pretightening force needed for gear mechanism.Such as, the logarithm of groove can be 2 to or 3 right.
Master gear 1 and pinion 2 are so designed: when this at least one pair of groove is between two in the face of overlapping, there is angular displacement between the corresponding teeth of master gear 1 and pinion 2.In other words, for as two grooves of a pair, the angular displacement being designed to the center line of the corresponding teeth of its corresponding sides and master gear 1 and pinion 2 is different.
Spring 3,4 is also comprised according to the gear mechanism of disclosure embodiment.Spring 3,4 can be arranged at least one pair of groove.Please note: shown in Fig. 1 to 3 is the embodiment with two pairs of grooves, but the logarithm of groove is not limited thereto.As mentioned above, the logarithm of groove can be determined according to the size of pretightening force needed for gear mechanism.Illustration be 2 to or 3 right.
In one embodiment, selectively, the length when length of groove can be less than spring nature.In other words, elastic strain will be there is in the spring be arranged in groove.Thus, for gear mechanism provides initial pretightening force.
According to Fig. 4, the manufacture method according to gear mechanism of the present disclosure is described below.
As shown in Figure 4, in step S401, manufacture master gear and pinion, make master gear identical with the tooth of pinion, the center of master gear is with stationary axle, and the center of pinion is hole, pinion can rotate around the stationary axle of master gear, the side fitted of master gear and pinion is provided with at least one pair of groove, when at least one pair of groove is between two in the face of overlapping, there is angular displacement between master gear and the corresponding teeth of pinion.In one embodiment, master gear 1 and pinion 2 can such as be obtained by digital control processing.Certainly, the processing mode of master gear 1 and pinion 2 also can use the technological means of related domain other routine any.
In step S402, assembling master gear and pinion, to arrange spring respectively at least one pair of groove.
As follows according to the working principle of gear mechanism of the present disclosure:
As shown in Figure 1, when gear is initially installed, between the tooth between master gear 1 and pinion 2, there is angular displacement.
As shown in Figure 2, when gear mechanism is when engaging with other conventional gear, pinion 2 can compress the first spring 3 and the second spring 4, and the stationary axle around master gear 1 rotates.
In other words, the facewidth of gear mechanism and space width can adjust adaptively along with the actual state of the gear be engaged with.
