Abstract
Disclosed is a pair of half axle gear and planetary gear complementarily used, wherein the small tooth groove of the half axle gear protrudes upward for a boss, with the tooth end of the gear straight with the end of the boss. The small tooth groove of the planetary gear protrudes upward for a boss, with the tooth end of the gear straight with the end of the boss. For the technical proposal in the utility model, the half axle gear engages with the small tooth groove of the planetary gear for a boss and the small tooth groove of the gear is integrated with the tooth by the boss, which enhances the strength of the small end for tooth, makes the gear face capable of bearing more engagement pressure and impact resistance, and thereby the utility model achieves the result of enhancing the strength of the whole tooth and lengthening the operation life.
Description
Technical field:
Bevel gear pair of the present utility model belongs to mechanical manufacturing field, and is especially relevant with a kind of matching used differential gear and planetary pinion of gaining in strength and increasing the service life.
Background technique:
In mechanical field, a lot of engineering goods, engineering machinery, Transport Machinery and mining machinery essentially will be used differential gear and planetary pinion.In the prior art, differential gear and planetary structure as shown in Figure 1, it is a standard piece, the shortcoming of this standard piece gear is: because its tooth ends is a contraction from the big small end of holding, be tapering and form tangent plane thereby intensity not high, easy tooth-breaking, working life is shorter.
Summary of the invention:
The purpose of this utility model is to provide the differential gear and the planetary pinion of a pair of good usability that cooperatively interacts, its intensity height, long service life.
For reaching above-mentioned purpose, the utility model adopts following technological scheme:
A pair of matching used differential gear and planetary pinion, described differential gear small end teeth groove upwards forms a boss, and the wheel tooth ends of gear is concordant with the end of boss.
Described planetary pinion small end teeth groove upwards forms a boss, and the wheel tooth ends of gear is concordant with the end of boss.
Adopt technique scheme, because differential gear that the utility model cooperatively interacts and planetary small end teeth groove form boss, and the small end teeth groove and the denticle of gear are integral by the boss limit, such structure, increased tooth portion small end intensity, can make the flank of tooth bear bigger engaging pressure and impact resistance, thereby reach the effect that increases whole tooth portion's intensity and increase the service life.
Description of drawings:
Fig. 1 is a prior art structural representation of the present utility model;
Fig. 2 is a structural representation of the present utility model.
Embodiment:
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 2, be example with a kind of automotive rear axle differential gear, its matching used differential gear and planetary pinion, described differential gear 1 small end teeth groove upwards forms a boss 11, and the gear teeth 12 ends of gear are concordant with the end of boss.
Described planetary pinion 2 small end teeth groove upwards form a boss 21, and the gear teeth 22 ends of gear are concordant with the end of boss.
Adopt technique scheme, because differential gear that the utility model cooperatively interacts and planetary small end teeth groove form boss, gear small end teeth groove and denticle are fused, become enclosed type, such structure, increase tooth portion small end intensity, can make the flank of tooth bear bigger engaging pressure and impact resistance, thereby reached the effect that increases whole tooth portion's intensity and increase the service life.
Claims (2)
1, a pair of matching used differential gear and planetary pinion is characterized in that: described differential gear small end teeth groove upwards forms a boss, and the wheel tooth ends of gear is concordant with the end of boss.
2, a pair of matching used differential gear as claimed in claim 1 and planetary pinion is characterized in that: described planetary pinion small end teeth groove upwards forms a boss, and the wheel tooth ends of gear is concordant with the end of boss.
