Description
Technical field
The utility model relates to gear shaft technical field, specifically a kind of gear shaft for automobile.
Background technique
Automobile gear axle 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, there is the defects such as complex structure, wear resistance be bad in existing technology.And gear shaft and gear are separate machined, then connected by key, because automobile gear axle is generally long, in order to increase the intensity of gear shaft, the diameter of gear shaft should be increased as far as possible, when the diameter of gear shaft increases, increase corresponding to the endoporus of the gear that gear axle key connects, and spatial constraints in automobile gear teeth tips diameter of a circle, bore increases backgear wheel tooth height and reduces, can reduce the intensity of gear, operationally gear easily ruptures.
Model utility content
The purpose of this utility model is the gear shaft for automobile providing a kind of structure simple, easy to use, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme:
A kind of gear shaft for automobile, comprise gear shaft body and gear, described gear shaft body comprises spindle nose end, axle stage casing and shaft tail end, described spindle nose end and shaft tail end are all one-body molded with axle stage casing, the centre in described axle stage casing is provided with linkage section, the joint of axle stage casing and linkage section is also provided with annular groove, the outside diameter of described linkage section is greater than the outside diameter in axle stage casing, the excircle of linkage section is provided with some limiting stoppers, the inner side of described gear be provided with some match with limiting stopper and groove, gear is fixed on linkage section by limiting stopper with coordinating of groove, and gear and linkage section weld together, the outside of gear shaft body is also provided with counter-bending back-up coat, the outside of described counter-bending back-up coat is provided with wearing layer, the left end of described spindle nose end offers spacing hole.
As further program of the utility model: the thickness of described counter-bending back-up coat is 4 ~ 8mm.
As further program of the utility model: the rear degree of described wearing layer is 2 ~ 4mm.
As the utility model further scheme: the outside of described gear is also provided with wearing layer.
Compared with prior art, the beneficial effects of the utility model are: the joint in linkage section and axle stage casing is provided with groove of remodeling, and annular groove may be used for transition, avoid stress to concentrate.Gear and linkage section weld together, and the diameter that can increase gear shaft body most possibly ensures the height of the gear teeth on gear simultaneously, thus ensure the intensity of gear, make gear not easy-rupturing, gear and linkage section are fixed by groove and limiting stopper, and enhance transmitting torque, intensity is high, good stability, gear is provided with wearing layer, can extend the working life of gear, is also provided with counter-bending back-up coat, make gear shaft resistance to bending good, effectively can improve stability and the working life of transmission.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of gear shaft for automobile, comprise gear shaft body 1 and gear 12, described gear shaft body 1 comprises spindle nose end 8, axle stage casing 2 and shaft tail end 7, and described spindle nose end 8 is all one-body molded with axle stage casing 2 with shaft tail end 7, the centre in described axle stage casing 2 is provided with linkage section 3, axle stage casing 2 is also provided with annular groove 10 with the joint of linkage section 3, and annular groove 10 may be used for transition, avoids stress to concentrate.The outside diameter of described linkage section 3 is greater than the outside diameter in axle stage casing 2, the excircle of linkage section 3 is provided with some limiting stoppers 11, the inner side of described gear 12 be provided with some match with limiting stopper 11 and groove 13, gear 12 is fixed on linkage section 3 by limiting stopper 11 with coordinating of groove 13, enhance transmitting torque, intensity is high, good stability, and gear 12 and linkage section 3 weld together, the diameter that can increase gear shaft body 1 most possibly ensures the height of the gear teeth on gear 12 simultaneously, thus ensure the intensity of gear 12, make gear 12 not easy-rupturing, the outer installment of gear 12 has wearing layer 6, the working life of gear 12 can be extended.
The outside of gear shaft body 1 is also provided with counter-bending back-up coat 5, and the thickness of counter-bending back-up coat 5 is 4 ~ 8mm, makes gear shaft resistance to bending good, effectively can improve stability and the working life of transmission.The outside of counter-bending back-up coat 5 is provided with wearing layer 6, and the rear degree of described wearing layer 6 is 2 ~ 4mm, and the left end of described spindle nose end 8 offers spacing hole 9.
