Small, compact structure has, the manufacturing is convenient, the quality is reliable, convenient characteristics are dismantled to the bearing.
Description
Technical field
The utility model relates to a kind of differential art field, is specifically related to the package assembly of spiral bevel gear and differential casing.
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) 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
The package assembly aiming to provide a kind of spiral bevel gear and differential casing of the present utility model, has that volume is little, a feature of compact structure, easily manufactured, reliable in quality, and facilitates the dismounting of bearing.
For this reason, the technological scheme that the utility model adopts is: the package assembly of a kind of spiral bevel gear and differential casing, described differential casing adopts integrally casting shaping, the middle part of differential casing is provided with sphere inner chamber, half axis hole communicated with sphere inner chamber is provided with at two of differential casing, 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, 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 planetary gear shaft hole of differential carrier, and be fixed by screws on spiral bevel gear setting circle, the thickness H of described spiral bevel gear must not be less than the distance L of planetary gear shaft hole to spiral bevel gear setting circle, 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) thickness limiting spiral bevel gear is greater than the distance of planetary gear shaft hole to spiral bevel gear setting circle, the two ends of planet pin are made to be against on the inwall of spiral bevel gear, prevent planet pin from moving axially by spiral bevel gear, not needing, spring bolt is set in addition and fixes;
(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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the worm's eye view of differential casing in Fig. 1.
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. 2, the package assembly of a kind of spiral bevel gear and differential casing, is made up of differential casing 1 and spiral bevel gear 2 two-part.
Differential casing 1 adopts integrally casting shaping, is provided with sphere inner chamber 1a for holding planetary pinion and differential gear at the middle part of differential casing 1.The half axis hole 1b that communicates with sphere inner chamber 1a is provided with for installing semiaxis at two of differential casing 1.Differential mechanism, to while the semiaxis transferring power of both sides, allows both sides semiaxis to rotate with different rotating speeds, meets two sidecar wheels and makes Unequal distance with the form of pure rolling as far as possible and travel, reduce the friction on tire and ground.
Half axis hole 1b inwall is provided with helix oil groove 1c, and preferably, the helix angle of helix oil groove 1c is 45 degree.
Differential casing 1 is provided with the planetary gear shaft hole 1d of lateral direction penetrating sphere inner chamber 1a for installing planet pin, two planetary pinions are sleeved on planet pin relatively, and planetary pinion engages with differential gear.The outer wall of differential casing 1 horizontally outward extends to form spiral bevel gear setting circle 1e, and spiral bevel gear 2 is sleeved on the outer side near planetary gear shaft hole 1d of differential casing 1, and is fixed by screws on spiral bevel gear setting circle 1e.
The thickness H of spiral bevel gear 2 must not be less than the distance L of planetary gear shaft hole 1d to spiral bevel gear setting circle 1e, makes the two ends of planet pin be against on the inwall of spiral bevel gear 2, exits to prevent planet pin in planetary gear shaft hole 1d.Spiral bevel gear 2 drives differential casing 1 to rotate together, and spiral bevel gear 2 is connected with the power input shaft of differential mechanism.
On differential casing 1 outer wall, just to the link position place of sphere inner chamber 1a and half axis hole 1b, be provided with pair of bearings dismounting clamping short slot 1f, and arranging in the axis bilateral symmetry of half axis hole 1b.
