Description
Technical field
The utility model belongs to technical field of mechanical transmission, is specifically related to a kind of gearbox driving gear shaft.
Background technique
Gearbox is made up of gear and axle, and produce variable-speed torque-converting by different Gear combination, its function mainly contains: 1, change velocity ratio; 2, in the constant situation of hand engine rotation, automobile can be fallen back traveling; 3, utilize neutral, interrupt transmission of power, to start to enable motor, idling, and be convenient to shifting of transmission or carry out Power output.Although existing gearbox driving gear shaft can meet usage requirement to a certain extent, still there is some deficiency following:
1, when assembling, driving gear shaft is difficult to look for position, and position is difficult to locking, causes difficulty to the assembling of gearbox;
2, driving gear driving gear shaft arranged is cylindrical gears, its profile of tooth is traditional wide profile of tooth, when being other gears meshing, certain centre distance error is inevitably there is between this driving gear and other gears, this engagement just causing two gears can not reach best, and then cause the reduction of noise and transmission efficiency.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of gearbox driving gear shaft, can not only position and lock easily, and can effective compensation centre distance error, reduces noise.
For achieving the above object, the utility model provides following technological scheme:
A kind of gearbox driving gear shaft, comprise gear shaft body, the two ends of described gear shaft body are respectively equipped with spline, and described gear shaft body is provided with the driving gear between the described spline of both sides; One end end face of described gear shaft body is provided with the locking screw for its position and lock, and all gear teeth of described driving gear are crowned teeth.
Further, the arc envelope face of the two side of the gear teeth of described driving gear all for being made up of circular curve.
Further, the two side of the gear teeth of described driving gear is arranged axisymmetricly.
Further, on the standard pitch circle cross section of described driving gear, the maximum ga(u)ge of the gear teeth of described driving gear and the difference of minimum thickness are 0.03mm.
Further, in described arc envelope face, the center of circle of all circular curves is all positioned on the straight line vertical with the axial space of described gear shaft body.
Further, described spline is involute splines or rectangular spline.
The beneficial effects of the utility model are:
Gearbox driving gear shaft of the present utility model, by arranging locking screw thread hole in one end-face, when assembling, can be locked easily by this locking screw thread hole, be convenient to the assembling of gearbox; By the gear teeth of driving gear are set to crowned teeth, it has the advantage that bearing capacity is strong, angular displacement compensation rate is large, noise is little and transmission efficiency is high, can centre distance error in effective compensation gear transmission.
Accompanying drawing explanation
In order to make the purpose of this utility model, technological scheme and beneficial effect clearly, the utility model provides following accompanying drawing to be described:
Fig. 1 is the structural representation of the utility model gearbox driving gear shaft embodiment;
Fig. 2 is the schematic cross-section of the gear teeth at standard pitch circle place of driving gear.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, and to make those skilled in the art better can understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.
As shown in Figure 1, be the structural representation of the utility model gearbox driving gear shaft embodiment.The gearbox driving gear shaft of the present embodiment, comprises gear shaft body 1, and the two ends of described gear shaft body 1 are respectively equipped with spline 2, and described gear shaft body 1 is provided with the driving gear 3 between the described spline 2 of both sides.One end end face of described gear shaft body 1 is provided with the locking screw 4 for its position and lock, and all gear teeth of described driving gear 3 are crowned teeth.Concrete, the arc envelope face 5 of two side all for being made up of circular curve of the gear teeth of driving gear 3, and the two side of the gear teeth of driving gear 3 is arranged axisymmetricly, can meet gear-driven requirement.
Further, on the standard pitch circle cross section of driving gear 3, the maximum ga(u)ge of the gear teeth of described driving gear 3 and the difference of minimum thickness: b-a=0.03mm, in arc envelope face 5, the center of circle of all circular curves is all positioned on the straight line vertical with the axial space of described gear shaft body 1, the crowned teeth of this structure is adopted to have the large advantage of load capacity, and the wear condition of the gear teeth can be improved, reduce noise.
Preferably, spline 2 is involute splines or rectangular spline, and the spline 2 of the present embodiment is involute splines, has processability good, and be slidably matched stable advantage.
The modulus m=1.5 of the spline of the present embodiment, tooth number Z=20, the modulus m=3 of driving gear, tooth number Z=15, and gear shaft body 1 is provided with the carburizing and quenching layer that the degree of depth is 0.8-1.2mm, can effectively improve surface hardness and wear-resisting property.
The gearbox driving gear shaft of the present embodiment, by arranging locking screw thread hole in one end-face, when assembling, can be locked easily by this locking screw thread hole, be convenient to the assembling of gearbox; By the gear teeth of driving gear are set to crowned teeth, it has the advantage that bearing capacity is strong, angular displacement compensation rate is large, noise is little and transmission efficiency is high, can centre distance error in effective compensation gear transmission.
The above embodiment is only for absolutely proving the preferred embodiment that the utility model is lifted, and protection domain of the present utility model is not limited thereto.The equivalent alternative or conversion that those skilled in the art do on the utility model basis, all within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with claims.
