Description
Technical field
The utility model discloses a kind of gear train assembly of eliminating the gear transmission gap, belongs to the technical field of gear train assembly.
Background technique
Common gear system is as shown in Figure 1: by gear A 1', gear B 2', be combined into a gear train assembly, there is no the transmission problem in general gear transmission, but gear transmission is required in high situation, for example, while requiring two gear transmission gaplesss, general gear transmission there will be following drive gap problem:
1. gear A 1', gear B 2' transverse tooth thickness in conventional machining is less than normal, therefore will produce the two-wheeled between cog in assembly process gapped.
2. gear A 1', gear B 2', in the normal operation process, also can produce wearing and tearing between the gear teeth of gear A 1', gear B 2', make transverse tooth thickness diminish, therefore along with running time longer generation two-wheeled between cog gap larger.
Having in the problems referred to above situation, do not reaching the purpose of accurate transmission between two gears.
The model utility content
The purpose of this utility model is to provide a kind of gear train assembly of eliminating the gear transmission gap, can realize the accurate transmission between two gears.
For achieving the above object, the technological scheme that the utility model adopts is:
A kind of gear train assembly of eliminating the gear transmission gap, the gear A and the gear B that comprise intermeshing setting, the upper-end surface of described gear A be concaved with one can accommodating free gear step surface, the number of teeth of this free gear, tip diameter, root diameter is all identical with gear A, the shaft axis of free gear overlaps with the shaft axis of gear A, this free gear is meshed with gear B simultaneously, the lower end surface of free gear is fixed with the stationary axle of downward protrusion, offer the containing groove that can hold this stationary axle on the step surface of gear A, also be provided with the pressurized elastomer in this containing groove, pressurized elastomer one end withstands the stationary axle sidewall, the other end withstands the containing groove sidewall.
As the further setting of such scheme, on the lower end surface of described gear A and the position corresponding with containing groove, offer counterbore, this counterbore is communicated with containing groove, coordinates protecting cover is installed in this counterbore simultaneously.The counterbore setting be communicated with containing groove, conveniently detachable and maintenance.
The upper end of described stationary axle fixedly is plugged in free gear, and the lower end of stationary axle extends down into to containing groove.
Described pressurized elastomer is compression spring.
A kind of gear train assembly of eliminating the gear transmission gap of the utility model, eliminate two gaps that are meshed between master gear by installing the free gear that can produce off normal additional, not only realized the accurate transmission between two gears, and simple in structure, practical.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The accompanying drawing explanation
Fig. 1 is the structural representation of existing ordinary gear transmission system;
Fig. 2 is a kind of structural representation of eliminating the gear train assembly in gear transmission gap of the utility model;
The A-A that Fig. 3 is Fig. 2 is to structural representation.
Embodiment
As Fig. 2, shown in Fig. 3, a kind of gear train assembly of eliminating the gear transmission gap of the utility model, the gear A 1 and the gear B 2 that comprise intermeshing setting, wherein the upper-end surface of gear A 1 be concaved with one can accommodating free gear 3 step surface 4, the number of teeth of this free gear 3, tip diameter, root diameter is all identical with gear A 1, the shaft axis of free gear 3 overlaps with the shaft axis of gear A 1, this free gear 3 is meshed with gear B 2 simultaneously, the lower end surface of free gear 3 is fixed with the stationary axle 5 of downward protrusion, offer the containing groove 6 that can hold this stationary axle 5 on the step surface 4 of gear A 1, also be provided with pressurized elastomer 7 in this containing groove 6, pressurized elastomer 7 one ends withstand stationary axle 5 sidewalls, the other end withstands containing groove 6 sidewalls.
For convenience of dismounting and maintenance, on the lower end surface of gear A 1 and the position corresponding with containing groove 6, offer counterbore 8, this counterbore 8 is communicated with containing groove 6, and the interior cooperation of this counterbore 8 simultaneously is equipped with protecting cover 9.
In the present embodiment, the structure that specifically arranges of stationary axle 5 is: it (is to offer groove on free gear 3 that the upper end of stationary axle 5 fixedly is plugged in free gear 3, the upper end of stationary axle 5 is inserted in groove, and fixing), the lower end of stationary axle 5 extends down into to containing groove 6.
In the present embodiment, pressurized elastomer 7 is preferably compression spring.
The utility model is a kind of, and to eliminate the working principle of gear train assembly in gear transmission gap as follows:
After the normal assembling engagement of gear A 1 and gear B 2, some gaps are arranged, the elimination of this gap is to be realized by free gear 3 off normals that are arranged on gear A 1, is close to the wheel flank of tooth of gear B 2 after the wheel flank of tooth off normal of free gear 3 and eliminates the gear backlash between gear A 1 and gear B 2.It is by stationary axle 5 this gear train assembly back lash of auto-compensation under the elasticity restitution power of pressurized elastomer 7 be fixed on free gear 3 that free gear 3 off normals are rotated.Because pressurized elastomer 7 one ends are close to the sidewall of stationary axle 5, the other end is close to the sidewall of containing groove 6, therefore pressurized elastomer 7 has a pressure promotion stationary axle 5 to force free gear 3 off normals to be rotated all the time, with this, guarantees this gear train assembly stable rotation under the tight mesh state.
Above-described embodiment is only for the inventive concept of the present utility model of explaining, but not to the restriction of the utility model rights protection, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should fall into protection domain of the present utility model.
