Abstract
The utility model discloses a driving mechanism of an electric actuator. The driving mechanism comprises a plurality of driving gears and universal driving shafts, wherein the universal driving shafts are connected with the plurality of driving gears and are polygonal shafts with regular polygonal cross sections, and the cross section of an inner hole of each driving gear matching each universal driving shaft is in shape of a regular polygon having the same structure as that of the cross section of the universal driving shaft. Through the structure, the cross sections of the universal driving shafts and the inner holes of the driving gears matching the universal driving shafts are in the shape of the regular polygon, so that a user can directly select the regular polygonal universal driving shafts and the driving gears with the regular polygonal inner holes during material selection, and compared with the prior art, the driving mechanism has the advantages of eliminating a machining process of a key slot and simplifying a whole machining process; and simultaneously, the linkage of the universal driving shafts and the driving gears is realized in a clamping manner, the mutual contact surfaces between the universal driving shafts and the driving gears are large, and the stress is uniform, so that the driving strength can be largely improved, and the damage to an associated component caused by insufficient driving strength can be prevented.
Description
Technical field
The utility model relates to a kind of YE, is specifically related to a kind of driving mechanism of YE.
Background technique
The driving mechanism of YE mainly by several driving gears and the couple axle that is used to connect driving gear constitute; But couple axle reaches the driving gear endoporus that is nested and joins with couple axle in the prior electric final controlling element driving mechanism at present; Its cross section is circle, and driving gear is realized through key with being connected mainly of couple axle, so not only added man-hour; Need on driving gear endoporus and couple axle, to offer the keyway that cooperates with key; Make processing become complicated loaded down with trivial details, and during transmission, the surface of contact of driving gear and couple axle and stress surface all concentrate on the key; Cause transmission insufficient strength, stressed also inhomogeneous, also bring infringement because of the transmission insufficient strength to related components easily.
Summary of the invention
To the deficiency of existing technology, the utility model provides a kind of easy to process, YE driving mechanism that transmission intensity is higher.
For realizing above-mentioned purpose; The utility model provides a kind of driving mechanism of YE; Comprise several driving gears and be used to connect the couple axle of driving gear; Described couple axle is the polygonal axle that cross section is regular polygon, with couple axle be nested the driving gear endoporus of joining cross section for the regular polygon of couple axle cross section same structure.
The beneficial effect of the utility model is: adopt said structure; Because couple axle that the utility model provided, and and the be nested cross section of the driving gear endoporus of joining of couple axle be regular polygon, so the user just can directly select for use regular polygon couple axle and endoporus to be the driving gear of regular polygon shape when selection, compares existing technology; Saved the manufacturing procedure of keyway; Make the whole machining process process more easy, couple axle and driving gear are to realize interlock through clamping simultaneously, and surface of contact each other is big, stressed evenly; Thereby can improve transmission intensity greatly, also can avoid the infringement that brings to related components because of the transmission insufficient strength.
It is that cross section is orthohexagonal polygonal axle that the utility model can further be set to described couple axle, and the endoporus of said driving gear also is the regular hexagon endoporus.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the cross sectional representation of couple axle in the utility model.
Embodiment
Provided a kind of driving mechanism of YE like Fig. 1, shown in 2; Comprise several driving gears 1 and be used to connect the couple axle 2 of driving gear 1, described couple axle 2 is orthohexagonal polygonal axle for cross section, with couple axle 2 be nested driving gear 1 endoporus of joining cross section for the regular hexagon of couple axle 2 cross section same structures; Therefore the user just can directly select for use regular hexagon couple axle 2 and endoporus to be the driving gear 1 of regular hexagon shape when selection; Compare existing technology, saved the manufacturing procedure of keyway, make the whole machining process process more easy; Couple axle 2 is to realize interlock through clamping with driving gear 1 simultaneously; Surface of contact each other is big, stressed evenly, thereby can improve transmission intensity greatly, also can avoid the infringement that brings to related components because of the transmission insufficient strength.
Claims (2)
1. the driving mechanism of a YE; Comprise several driving gears and be used to connect the couple axle of driving gear; It is characterized in that: described couple axle is the polygonal axle that cross section is regular polygon, with couple axle be nested the driving gear endoporus of joining cross section for the regular polygon of couple axle cross section same structure.
2. the driving mechanism of YE according to claim 1 is characterized in that: described couple axle is that cross section is orthohexagonal polygonal axle, and the endoporus of said driving gear also is the regular hexagon endoporus.
