It is reliable to make convenience, compact structure, intensity.
Description
Technical field
The utility model relates to differential art field, is specifically related to a kind of poor case of transmission facilitating manufacturing.
Background technique
Differential mechanism is assembled by differential casing, planetary pinion, differential gear, semiaxis and planet pin.Differential casing serves as planetary wheel carrier, and planetary pinion, differential gear, semiaxis and planet pin are arranged in differential casing.Differential casing adopts integrally casting shaping usually, inner chamber is provided with for holding planetary pinion and differential gear at the middle part of housing, two of housing is provided with half axis hole that communicates with inner chamber for installing semiaxis, housing is provided with the planetary gear shaft hole of lateral direction penetrating inner chamber for installing planet pin, the outer wall of housing horizontally outward extends to form spiral bevel gear setting circle for installing fixing spiral bevel gear.
The subject matter that existing structure exists is: (1) half shaft hole inner wall is provided with helical oil groove, must be added and form, add one technique by machine; (2) inner chamber is curved surface, and holding space is little, and the overall dimensions of differential casing is higher; (3) the housing wall thickness at spiral bevel gear setting circle root position place is thinner, have impact on the bulk strength of differential casing.
Model utility content
Of the present utility modelly aim to provide a kind of easily manufactured, reliable differential casing of compact structure, intensity.
For this reason, the technological scheme that the utility model adopts is: a kind of poor case of transmission facilitating manufacturing, employing integrally casting is shaping, the middle part of described housing is provided with sphere inner chamber for holding planetary pinion and differential gear, two of housing is provided with half axis hole communicated with sphere inner chamber, housing is provided with the planetary gear shaft hole of lateral direction penetrating sphere inner chamber, the outer wall of housing horizontally outward extends to form spiral bevel gear setting circle, described housing is provided with the positioning pin hole of a longitudinal extension for locking the planet pin of planetary gear shaft hole, described spiral bevel gear setting circle is distributed with gear fastener hole, the side root of described spiral bevel gear setting circle is provided with round platform, described round platform is provided with the locating stud corresponding with positioning pin hole to step down breach, described half shaft hole inner wall is distributed with the straight oil groove of at least two longitudinal extensions.
The beneficial effects of the utility model: set up round platform at the side root of spiral bevel gear setting circle, the housing wall thickness at this position is avoided to affect bulk strength not, because positioning pin hole just in time will be bored in this position, on round platform, correspondence arranges locating stud and to step down breach, avoids increasing drilling depth; Sphere inner chamber can increase the volume of inner chamber, and the external frame of planetary pinion, differential gear mates with sphere inner chamber, reduces the whole height of differential casing, makes overall structure more compact; Half shaft hole inner wall is provided with straight oil groove, is formed in casting process, eliminate one machining sequence.

Embodiment
Below by embodiment also by reference to the accompanying drawings, the utility model is described in further detail:
Shown in composition graphs 1-Fig. 4, a kind of poor case of transmission facilitating manufacturing, adopt integrally casting shaping, the middle part of housing is provided with sphere inner chamber 1 for holding planetary pinion and differential gear, and planetary pinion and differential gear are arranged in sphere inner chamber 1.Two of housing is provided with half axis hole 2 communicated with sphere inner chamber 1, be respectively used to semiaxis (i.e. output shaft) is installed, differential mechanism is to while the semiaxis transferring power of both sides, both sides semiaxis is allowed to rotate with different rotating speeds, meet two sidecar wheels and make Unequal distance traveling with the form of pure rolling as far as possible, reduce the friction on tire and ground.
Housing is provided with the planetary gear shaft hole 3 of lateral direction penetrating sphere inner chamber 1, for installing planet pin, two planetary pinions are sleeved on planet pin relatively.The outer wall of housing horizontally outward extends to form spiral bevel gear setting circle 4, spiral bevel gear setting circle 4 is for installing spiral bevel gear, spiral bevel gear is fixedly mounted on spiral bevel gear setting circle 4, and drives differential casing to rotate together, is connected with the power input shaft of differential mechanism.
Housing is provided with the positioning pin hole 7 of a longitudinal extension for installing locating stud, locating stud inserts on the planet pin of locking planetary gear shaft hole 3, exits in planetary gear shaft hole 3 to prevent planet pin.
Spiral bevel gear setting circle 4 is distributed with gear fastener hole 6, spiral bevel gear by screw lock on spiral bevel gear setting circle 4.The side root of spiral bevel gear setting circle 4 is provided with round platform 5, round platform 5 is provided with the locating stud corresponding with positioning pin hole 7 and steps down breach 5a.Half axis hole 2 inwall is distributed with the straight oil groove 8 of at least two longitudinal extensions.
Preferably, the gear fastener hole 6 on spiral bevel gear setting circle 4 totally eight.Each half axis hole 2 inwall is evenly equipped with three straight oil grooves 8, but is not limited to three.
Claims (2)
