Abstract
The utility model relates to a honeycomb type gear infinitely variable speed mechanism, composed of a driving gear, a middle gear, a driven gear and a rotary shaft. The driving gear is in a circular disk shape, a concave honeycomb-shaped tooth is arranged on the driving gear, and the central part of the circular disk is larger than the circle of the honeycomb-shaped tooth. The driven gear is in a column shape, and a concave honeycomb-shaped tooth is arranged on the surface of the column. The middle gear is in a ball shape, and the surface of the middle gear is provided with a convex honeycomb-shaped tooth. The utility model realizes infinitely variable speed.
Description
The utility model relates to a kind of gear, especially a kind of duolateral gear stepless variable drive structure.
Present mechanical type gear owing to be subjected to the restriction of existing gear characteristic, in fact is difficult to reach real infinite variable speed requirement.
The novel purpose of this reality is to provide a kind of can realize infinite variable speed duolateral stepless speed changing mechanism preferably.
The utility model is made up of driving gear, intermediate gear, driven gear and transmission shaft, it is characterized in that described driving gear is one discoid, and it is a circle greater than cellular tooth that recessed cellular tooth and disc centre portion are arranged on the disc face; Driven gear is cylindrical, and recessed cellular tooth is arranged on the cylndrical surface; Intermediate gear is a spheroidal, there is the cellular tooth of projection on the surface, the double wedge of above-mentioned intermediate gear respectively with the recessed tooth engagement of driving gear, driven gear, there be fixing watt on the intermediate gear, above-mentioned fixing watt for being wrapped in the annulus of gear ball on one week, on two relative summits of this annulus round frontal axis tray is arranged, in the bearing dish ball is arranged.
The utility model proposes a kind of brand-new kind of drive, realized stepless change preferably.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model driving gear Facad structure schematic representation.
Fig. 3 is the tooth-shape structure schematic representation of the utility model driving gear and driven gear.
Fig. 4 is the structural representation of the utility model intermediate gear and fixing watt, bearing dish.
Fig. 5 is that the utility model Fig. 4 A is to view.
With reference to accompanying drawing, the utility model is made up of driving gear (7), intermediate gear (8), driven gear (3) and transmission shaft (2), its driving gear is one discoid, and it is a circle greater than cellular tooth (9) that recessed cellular tooth and disc centre portion are arranged on the disc face; Driven gear is cylindrical, and recessed cellular tooth is arranged on the cylndrical surface, and driven gear adopts spline to be connected with transmission shaft and can slide on transmission shaft; Intermediate gear is a spheroidal, there is the cellular tooth of projection on the surface, the double wedge of above-mentioned intermediate gear respectively with driving gear, the recessed tooth engagement of driven gear, fixing watt (6) are arranged on it, fixing watt is connected in slide bar (5) by sliding sleeve (4) and goes up also and can slide along the slide bar direction, fixing watt for being wrapped in the annulus of gear ball on one week, on two relative summits of this annulus round frontal axis tray (11) is arranged, ball (10) is arranged in the bearing dish, during proper functioning, because the effect of two relative summit upper bearing (metal) dishes of annulus, be rolling friction between intermediate gear ball and fixing watt, friction is very little during high speed rotating, when center tooth wheel ball along slide bar (5) when direction moves, between intermediate gear ball and the fixing watt base be sliding friction, thereby the intermediate gear ball can rotate by any direction in fixing watt, can pass through bevel gear (1) and assist with the change transmission direction in practicality.The utility model working procedure is as follows: when driving gear rotated, the rotating speed and the sense of rotation of driven gear determined in the position at intermediate gear place, when intermediate gear has the initiative the gear edge place, and driven gear rotating speed height; Intermediate gear is when the driving gear neutral position, and the driven gear rotating speed is low; When intermediate gear had the initiative the gear center position, driven gear then was in halted state; When intermediate gear moved on to the driving gear another side, driven gear is backward rotation then.
Claims (3)
1, a kind of duolateral gear stepless variable drive structure, form by driving gear, intermediate gear, driven gear and transmission shaft, it is characterized in that described driving gear is one discoid, it is a circle greater than cellular tooth that recessed cellular tooth and disc centre portion are arranged on the disc face; Driven gear is cylindrical, and recessed cellular tooth is arranged on the cylndrical surface; Intermediate gear is a spheroidal, and there is the cellular tooth of projection on the surface, the double wedge of intermediate gear respectively with the recessed tooth engagement of driving gear, driven gear, have fixing watt on the intermediate gear.
2, duolateral gear stepless variable drive structure as claimed in claim 1 is characterized in that described fixing watt is to be wrapped in the annulus of gear ball on one week.
3, duolateral gear stepless variable drive structure as claimed in claim 2 is characterized in that on two relative summits of described annulus round frontal axis tray being arranged, and in the bearing dish ball is arranged.
