Abstract
The utility model relates to a kind of gear shaft assembly, comprise master gear, pinion, gear shaft, described master gear and described pinion are equipped with through hole, the position of described gear shaft 1/4th length is provided with teething ring, described gear shaft inserts in the through hole of described pinion and described master gear, the end of described teething ring and described pinion fits tightly, described master gear end is provided with master gear disk, described master gear disk bottom is provided with groove, described pinion head inserts in the groove of described master gear end, and the bi-side of described pinion are stepped.Adopt said structure, master gear end is provided with groove, and pinion nose shape is consistent with the groove on master gear, master gear is connected with pinion and more closely not easily rotates, increase the resistance to torsion of whole gear shaft assembly.This gear assembly structure is simple, is easy to split, and is convenient to user's maintenance and changes.
Description
Technical field
The utility model belongs to transmission accessory field, is specifically related to a kind of gear shaft assembly.
Background technique
Gear shaft refers to that support rotary part turning round therewith transmits the mechanical parts of motion, moment of torsion or moment of flexure.Be generally round metal shaft-like, each section can have different diameters.The part doing rotation motion in machine is just contained on axle, is a kind of easily damaged parts.Existing gear shaft modular support is oversize to be caused axle to want overstriking and increases mechanical strength (as rigidity, amount of deflection, bending resistance etc.), and its interchangeability is poor, and dismounting difficulty, brings very large inconvenience to the C&M of equipment.
Model utility content
Problem to be solved in the utility model is to provide a kind of being easy to and dismantles, is convenient to maintain and the gear shaft assembly changed.
In order to solve technique scheme, the utility model adopts following technological scheme:
A kind of gear shaft assembly, comprise master gear, pinion, gear shaft, described master gear and pinion are equipped with through hole, the inner wall smooth of described through hole, the internal diameter of described through hole is greater than the diameter of described gear shaft, the position of described gear shaft 1/4th length is provided with teething ring, described gear shaft inserts in described through hole, the end of described teething ring and described pinion fits tightly, described master gear end is provided with master gear disk, described master gear disk bottom is provided with groove, the degree of depth of described groove is less than the thickness of described master gear disk, the shape of described groove is consistent with the shape of pinion head, described pinion head inserts in the groove of described master gear end, the bi-side of described pinion are stepped.
The number of teeth that the utility model can be set to described master gear is further 8.
The shape that the utility model can be set to described groove is further long limit is wave, and minor face is the quadrilateral of straight line.
The degree of depth that the utility model can be set to described groove is further 1/2nd of the thickness of described master gear disk.
It is hypotenuse that the utility model can be set to described master gear disk further relative to wheel flank.
The beneficial effects of the utility model: adopt said structure, master gear end is provided with groove, and pinion nose shape is consistent with groove shapes, master gear is connected with pinion and more closely not easily rotates, increase the resistance to torsion of whole gear shaft assembly.This gear assembly structure is simple, is easy to split, and is convenient to user's maintenance and changes.

Embodiment
Referring to figs. 1 through Fig. 4, a kind of gear shaft Assemblies Example of the utility model is described further.
A kind of gear shaft assembly, comprise master gear 1, pinion 2, gear shaft 3, described master gear 1 and pinion 2 are equipped with through hole 4, the inner wall smooth of described through hole 4, the internal diameter of described through hole 4 is greater than the diameter of described gear shaft 3, the position of described gear shaft 1/3rd four length is provided with teething ring 5, described gear shaft 3 inserts in described through hole 4, described teething ring 5 fits tightly with the end of described pinion 2, described master gear 1 end is provided with master gear disk 6, groove 7 is provided with bottom described master gear disk 6, the degree of depth of described groove 7 is less than the thickness of described master gear disk 6, the shape of described groove 7 is consistent with the shape of pinion 2 head, described pinion 2 head inserts in the groove 7 of described master gear 1 end, the bi-side of described pinion 2 are stepped.
The number of teeth that the utility model can be set to described master gear 1 is further 8.
The shape that the utility model can be set to described groove 7 is further long limit is wave, and minor face is the quadrilateral of straight line.
The degree of depth that the utility model can be set to described groove 7 is further 1/2nd of the thickness of described master gear disk 6.
It is hypotenuse 9 that the utility model can be set to described master gear disk 6 further relative to the gear teeth 8 side.
The beneficial effects of the utility model: adopt said structure, master gear 1 end is provided with groove 7, and pinion 2 nose shape is consistent with groove 7 shape, master gear 1 is connected with pinion 2 and more closely not easily rotates, increase the resistance to torsion of whole gear shaft assembly.This gear assembly structure is simple, is easy to split, and is convenient to user's maintenance and changes.
