Description
Technical field
The utility model relates to differential art field, is specifically related to a kind of differential casing.
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.Housing is provided with the positioning pin hole of a longitudinal extension for installing spring bolt, spring bolt, for planet pin is locked at differential casing, prevents planet pin from exiting in planetary gear shaft hole.
The subject matter that existing structure exists is: (1) spiral bevel gear is fixed by screws in spiral bevel gear setting circle, for ensureing enough worm tooth numbers, needs the thickness increasing spiral bevel gear setting circle, cause differential casing always great, manufacture cost is high; (2) 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 that a kind of volume is little, lightweight, the reliable differential casing of low cost of manufacture, intensity.
For this reason, the technological scheme that the utility model adopts is: a kind of differential casing, employing integrally casting is shaping, the middle part of described housing is provided with inner chamber for holding planetary pinion and differential gear, two of housing is provided with half axis hole communicated with inner chamber, housing is provided with the planetary gear shaft hole of lateral direction penetrating 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, it is characterized in that: the side hoop of described spiral bevel gear setting circle is distributed with reinforcement platform, each reinforcement platform is provided with the gear fastener hole of a through spiral bevel gear setting circle of longitudinal direction, the root of described spiral bevel gear setting circle opposite side is provided with round platform, described round platform is provided with the locating stud corresponding with positioning pin hole to step down breach.
Preferred as such scheme, the inner chamber of described housing is sphere; Correspondingly, the external frame of planetary pinion, differential gear mates with sphere inner chamber, arranges sphere inner chamber, can increase the volume of inner chamber, reduces the whole height of differential casing, makes overall structure more compact.
The beneficial effects of the utility model: by setting up reinforcement platform in the side of spiral bevel gear setting circle, for arranging gear fastener hole, can ensure the tooth number of screw thread, again can weight reduction, reduce costs; Set up round platform at the opposite side root of spiral bevel gear setting circle, avoid the housing wall thickness at this position 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.

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 differential casing, adopt integrally casting shaping, the middle part of housing is provided with inner chamber 1 for holding planetary pinion and differential gear, and planetary pinion and differential gear are arranged in inner chamber 1.Two of housing is provided with half axis hole 2 communicated with 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 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 8 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.
The side hoop of spiral bevel gear setting circle 4 is distributed with strengthens platform 5, and each reinforcement platform 5 is provided with the gear fastener hole 6 of a through spiral bevel gear setting circle 4 of longitudinal direction, spiral bevel gear is arranged on the one side not arranging and strengthen platform 5, and passes through screw lock.The root of spiral bevel gear setting circle 4 opposite side is provided with round platform 7, round platform 7 is provided with the locating stud corresponding with positioning pin hole 8 and steps down breach 7a.
Preferably, the inner chamber 1 of housing is sphere.Reinforcement platform 5 on spiral bevel gear setting circle 4 totally eight, and circumferentially uniform; Gear fastener hole 6 and reinforcement platform 5 one_to_one corresponding, be therefore also eight.
