Small, compact structure, the manufacturing is convenient, the quality is reliable.
Description
Technical field
The utility model relates to a kind of differential art field, is specifically related to the mounting structure of differential mechanism and spiral bevel gear.
Background technique
Differential mechanism 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.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) half shaft hole inner walls are provided with helical oil groove, must be added by machine and form, add one technique.
Model utility content
The mounting structure aiming to provide a kind of differential mechanism and spiral bevel gear of the present utility model, has that volume is little, a feature of compact structure, easily manufactured, reliable in quality.
For this reason, the technological scheme that the utility model adopts is: the mounting structure of a kind of differential mechanism and spiral bevel gear, described differential mechanism comprises 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 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.
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) half shaft hole inner walls are provided with straight oil groove, are formed in casting process, eliminate one machining sequence.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below by embodiment also by reference to the accompanying drawings, the utility model is described in further detail:
As shown in Figure 1, the mounting structure of a kind of differential mechanism and spiral bevel gear, forms primarily of differential casing 1, planet pin 2, spiral bevel gear 3, planetary pinion 4 and differential gear 5.Wherein, differential casing 1, planet pin 2, planetary pinion 4 and differential gear 5 constitute differential mechanism.
Differential casing 1 adopts integrally casting shaping, the middle part of differential casing 1 is provided with sphere inner chamber, planetary pinion 4 and differential gear 5 are arranged in sphere inner chamber, two of differential casing 1 is provided with the half axis hole 1a that communicates with sphere inner chamber for installing semiaxis, differential mechanism is to while the semiaxis transferring power of both sides, allow both sides semiaxis 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.
Half axis hole 1a inwall is distributed with the straight oil groove 1b of longitudinal extension.Preferably, each half axis hole 2 inwall is evenly equipped with three straight oil groove 1b, but is not limited to three.
Differential casing 1 is provided with the planetary gear shaft hole of lateral direction penetrating sphere inner chamber, planet pin 2 is arranged in planetary gear shaft hole, planetary pinion 4 is sleeved on planet pin 2, two planetary pinions are sleeved on planet pin relatively, and planetary pinion 4 engages with differential gear 5, the outer wall of differential casing 1 horizontally outward extends to form spiral bevel gear setting circle, spiral bevel gear 3 is sleeved on the outer side near planet pin 2 of differential casing 1, and be fixed by screws on spiral bevel gear setting circle, spiral bevel gear 3 drives differential casing 1 to rotate together, spiral bevel gear 3 is connected with the power input shaft of differential mechanism.The two ends of planet pin 2 are against on the inwall of spiral bevel gear 3, exit in planetary gear shaft hole to prevent planet pin 2.
Preferably, on the inwall being against spiral bevel gear 3 over half of planet pin 2 end face, enlarge active surface, guarantees that planet pin 2 axis can not occur and moves.
