Description
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, spiral bevel 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) for preventing planet pin from exiting planetary gear shaft hole, usually also need to wear spring bolt for fixing planet pin on differential casing; (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, the differential assembly of compact structure, easily manufactured, reliable in quality, and facilitate the dismounting of bearing.
For this reason, the technological scheme that the utility model adopts is: a kind of differential assembly with spiral bevel gear, comprise differential casing, planet pin, spiral bevel gear, 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 provided with helix oil groove, 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 is sleeved on the external side near planet pin of differential carrier, and be fixed by screws on spiral bevel gear setting circle, the two ends of described planet pin are against on the inwall of spiral bevel gear, 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 arranging in the axis bilateral symmetry of half axis hole.
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) two ends of planet pin are against on the inwall of spiral bevel gear, prevent planet pin from moving axially by spiral bevel gear, do not need to arrange spring bolt in addition and fix;
(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.
