Abstract
The utility model provides a kind of low noise driving gear splined shaft, and it includes axis body（1）, it is characterised in that：In axis body（1）On be evenly equipped with the spline gear teeth of one group and pinion flange corresponding matching（2）, and the described spline gear teeth（2）Carry helical angle.The utility model is simple in construction, easy to process so that power transmission is more steady, reduces play between flange of cardinal tooth and main tooth, and then reduce the main risk for subtracting assembly oil leak.
Description
Technical field：
The utility model is related to auto parts and components field, is exactly specifically a kind of low noise driving gear splined shaft.
Background technology：
Driving gear is the kernel component of drive axle, the end in PWTN, its basic function be increase by
The torque that power transmission shaft or speed changer are transmitted, reduces its rotating speed transmitted.And driving gear is then convex with driving gear by splined shaft
Edge is connected to form transmission, and the tooth spline modulus on the splined shaft used at present is big, and tooth number is few, tooth distribution it is uneven and
Gap is big between the gear teeth, can not completely be in close contact to cause to exist between flange assembly and driving gear with flange internal spline and alter
It is dynamic.There is impact, influence driver's operation in power train process.Simultaneously both gap is larger has easily caused main deceleration assembly oil leak
Risk.
Utility model content：
The utility model is exactly that there is provided a kind of low noise driving gear splined shaft in order to overcome deficiency of the prior art.
The utility model provides following technical scheme：
A kind of low noise driving gear splined shaft, it includes the axis body with bearing block corresponding matching, is provided with axis body one end
The driving gear gear teeth, it is characterised in that：The spline gear teeth of one group and pinion flange corresponding matching are evenly equipped with axis body, and
The described spline gear teeth carry helical angle.
On the basis of the volume of above-mentioned technical proposal, there can also be technical scheme further below：
The angle of described helical angle is 21'-27'.
Utility model advantage：
The utility model has the advantages that simple in construction, easy to process, enables the spline gear teeth especially by helical angle
It can be in close contact completely with the internal spline of pinion flange；So that power transmission it is more steady, reduce flange of cardinal tooth with
Play between initiative gear assembly, and then reduce the risk of main deceleration assembly oil leak.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model.
Embodiment：
As shown in figure 1, a kind of low noise driving gear splined shaft, it includes axis body 1, and bearing block is inserted in the lower end of axis body 1
3, then it is then passed through after the driving gear inner bearing 3a in bearing block 3, driving gear 4, and described axle is additionally provided with its end
Body 1 is integral type structure with driving gear 4.
Be evenly equipped with one group of spline gear teeth 2 on the axis body 1 of the top of driving gear 4, the described spline gear teeth 2 respectively with actively
Gear inner bearing 3a and the formation corresponding matching of pinion flange 5 of the top of bearing block 3, and one group of described spline gear teeth 2
Modulus it is smaller, the gear teeth are more, are evenly distributed with helical angle between each gear teeth, and the angle of described helical angle is 21'-27'.
The helical angle of the spline gear teeth enables the internal spline of the spline gear teeth and pinion flange to be in close contact completely, so that dynamic
Power transmission is more steady, reduces play between flange of cardinal tooth and initiative gear assembly, and then reduce the risk of main deceleration assembly oil leak.
The flange with the corresponding matching of pinion flange 2 is additionally provided with the axis body 1 of the described top of pinion flange 5
Fixing nut 6.
