Technical field
The utility model relates to a kind of differential assembly, belongs to mechanical structure technical field.
Background technique
Differential assembly is assembled by differential casing, planetary pinion, differential gear and planet pin.Differential casing serves as planetary wheel carrier, and planetary pinion, differential gear 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 differential casing, two of differential casing is provided with half axis hole that communicates with inner chamber for installing semiaxis, differential casing is provided with the planetary gear shaft hole of lateral direction penetrating inner chamber for installing planet pin, the outer wall of differential casing 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) inner chamber is curved surface, and holding space is little, and the overall dimensions of differential casing is higher; (2) half shaft hole inner walls are provided with helical oil groove, must be added by machine and form, add one technique; (3) be set with bearing outside the two ends of differential casing, when the external diameter of bearing is too small, extracting tool cannot reach between the spherical outer wall section of differential casing and bearing termination, dismantles very difficult.
Model utility content
Of the present utility modelly aim to provide that a kind of volume is little, compact structure, easily manufactured differential assembly, and facilitate the dismounting of bearing.
For this reason, the technological scheme that the utility model adopts is: a kind of differential assembly facilitating bearing removal, comprise differential casing, planet pin, planetary pinion and differential gear, described differential casing adopts integrally casting shaping, the middle part of differential casing is provided with sphere inner chamber, described planetary pinion and differential gear are arranged in sphere inner chamber, two of differential casing is provided with half axis hole communicated with sphere inner chamber, described half shaft hole inner wall is distributed with the straight oil groove of longitudinal extension, differential casing is provided with the planetary gear shaft hole of lateral direction penetrating sphere inner chamber, described planet pin is arranged in planetary gear shaft hole, planetary pinion is sleeved on planet pin, and planetary pinion engages with differential gear, the outer wall of differential casing horizontally outward extends to form spiral bevel gear setting circle, described spiral bevel gear setting circle is provided with circumferentially uniform mounting hole, on described differential casing outer wall, just to the link position place of sphere inner chamber and half axis hole, be provided with pair of bearings dismounting clamping short slot, and arrange in the axis bilateral symmetry of half axis hole, the inwall of differential casing is provided with just to the reinforced block of bearing removal clamping short slot, to avoid the differential casing wall thickness at bearing removal clamping short slot present position place too thin.
The beneficial effects of the utility model:
(1) 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;
(2) half shaft hole inner walls are provided with straight oil groove, are formed in casting process, eliminate one machining sequence;
(3) on differential casing outer wall, just to the link position place of sphere inner chamber and half axis hole, set up pair of bearings dismounting clamping short slot, the bare terminal end that vacating space is used for bearing extractor is stretching into, and greatly facilitates the dismounting of bearing.
