Abstract
The utility model discloses a novel inter-axle differential comprising a differential shell body, and a semi-axle gear, a planetary gear and a cross axle which are fixed in the differential shell body; the semi-axle gear is provided with 16 teeth, the planetary gear is provided with 11 teeth, and the modulus of the semi-axle gear and the planetary gear is 7.25; and the axle diameter of the cross axle is 28mm. By changing the modulus and tooth number of a differential gear, the diameter of the cross axle and the front case of the differential and improving the strength of the gear, the novel inter-axle differential adjusts the front case structure of the inter-axle differential, adjusts and enhances the structure of an easily broken axle diameter part, and improves the fault of axle diameter breakage of the front case of the differential; the service life of the differential gear is prolonged, the differential gear is re-designed, the modulus of the gear is increased, the tooth number is adjusted, the axle diameter of the cross axle is thickened, and the purpose of prolonging the service life of a differential assembly is achieved by improving the strength of all links; and the inside of the differential is greatly adjusted, the size of an external interface is not changed, and the market interchangeability is not affected.
Description
Technical field
The utility model relates to a kind of interaxial differential, belongs to field of mechanical technique.
Background technique
At present, interaxial differential is in use owing to the Accident due to quality that fracture damage occurs is more and more, mainly show the fracture wear of differential mechanism fore shell, cross axle sintering, differential gear are beaten the tooth fault, thereby cause differential mechanism to damage, therefore need to improve the functional reliability of differential mechanism and the intensity of stability and differential casing.
The model utility content
Deficiency at the prior art existence, technical problem to be solved in the utility model is, a kind of interaxial differential is provided, improve the strength of gear teeth, the structural adjustment of easily broken diameter of axle place is strengthened, and has improved the fault of differential mechanism fore shell diameter of axle fracture, and the differential gear mission prolongs, improve each link intensity, reach the purpose of differential assembly life-span raising.
For solving the problems of the technologies described above, the technological scheme that the utility model is taked is, a kind of novel interaxial differential, comprise differential casing and be fixed in differential casing interior differential gear, planetary pinion and cross axle, the described differential gear number of teeth is 16, the planetary pinion number of teeth is 11, and differential gear and planetary modulus are 7.25; The diameter of axle of cross axle is 28mm.
Optimize, the diameter of axle at the easily broken diameter of axle place in the above-mentioned novel interaxial differential, its differential casing is 25mm.
The utility model improves the strength of gear teeth by changing the differential gear modulus and the number of teeth, cross axle diameter, differential mechanism fore shell, and the interaxial differential front casing structure is adjusted, and the structural adjustment of easily broken diameter of axle place is strengthened, and has improved the fault of differential mechanism fore shell diameter of axle fracture; The differential gear mission prolongs, the differential gear redesign, and module increases, number of teeth adjustment, the overstriking of the cross axle diameter of axle by improving each link intensity, reaches the purpose of differential assembly life-span raising; Bigger adjustment is made in differential mechanism inside, and the external interface size does not change, and does not influence market interchangeability.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described;
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of differential casing of the present utility model.
Embodiment
As shown in Figure 1, a kind of novel interaxial differential of the utility model comprises differential casing and is fixed in differential casing interior differential gear 1, planetary pinion 2 and cross axle 3 that the described differential gear number of teeth is 16, the planetary pinion number of teeth is 11, and differential gear and planetary modulus are 7.25; The diameter of axle of cross axle is 28mm.The diameter of axle at the easily broken diameter of axle place in the differential casing is 25mm.The functional reliability and stability of the utility model in order to improve differential mechanism optimized the differential mechanism fore shell differential gear redesign again, with respect to former interaxial differential, its intensity improves very obvious, and after the entrucking experimental verification, effect is very obvious.In the axle assembly of component parts for assembly of a machine more than 10000 of assembling in batches, through the market checking of 6 wheat harvesting periods, differential mechanism damage accident barrier reduces very obvious at present.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
