Abstract
The utility model discloses a differential housing adopts integrative casting shaping, is provided with the sphere inner chamber at differential housing's middle part, is provided with the helix oil groove on the halfshaft hole inner wall, the last planetary gear shaft hole of transversely lining up the sphere inner chamber that is provided with of differential housing, and differential housing's outer wall level is outwards extended and is formed the spiral bevel gear setting circle, be provided with the mounting hole that is the circumference equipartition on the spiral bevel gear setting circle, on the differential housing outer wall, just to the hookup location department of sphere inner chamber with halfshaft hole, be provided with a pair of bearing and dismantle the scarce groove of centre gripping to axis bilateral symmetry at halfshaft hole sets up, is provided with just to dismantle the boss that the centre gripping lacks the groove to the bearing on differential housing's inner wall, and is too thin with the differential housing wall thickness of avoiding the scarce groove present position department of bearing dismantlement centre gripping. Small, compact structure has, 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 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) 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 a kind of differential casing, have that volume is little, the feature of compact structure, and facilitate the dismounting of bearing.
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 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, and 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) 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, a kind of differential casing, adopting integrally casting shaping, being provided with sphere inner chamber 1 for holding planetary pinion and differential gear at the middle part of differential casing.Half axis hole 2 that communicates with sphere inner chamber 1 is provided with for installing semiaxis at two of differential casing.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 2 inwall is provided with helix oil groove 3, and preferably, the helix angle of helix oil groove 3 is 45 degree.
Differential casing is provided with the planetary gear shaft hole 4 of lateral direction penetrating sphere inner chamber 1 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 horizontally outward extends to form spiral bevel gear setting circle 5, spiral bevel gear setting circle 5 is provided with circumferentially uniform mounting hole, spiral bevel gear is sleeved on the external side near planetary gear shaft hole 4 of differential carrier, and is fixed by screws on spiral bevel gear setting circle 5.Spiral bevel gear drives differential casing to rotate together, and spiral bevel gear is connected with the power input shaft of differential mechanism.
On differential casing outer wall, just to the link position place of sphere inner chamber 1 and half axis hole 2, be provided with pair of bearings dismounting clamping short slot 6, and arrange in the axis bilateral symmetry of half axis hole 2, the inwall of differential casing is provided with just to the reinforced block of bearing removal clamping short slot 6, to avoid the differential casing wall thickness at bearing removal clamping short slot 6 present position place too thin.
Claims (2)
1. a differential casing, it is characterized in that: adopt integrally casting shaping, sphere inner chamber (1) is provided with at the middle part of differential casing, half axis hole (2) communicated with sphere inner chamber (1) is provided with at two of differential casing, described half axis hole (2) inwall is provided with helix oil groove (3), differential casing is provided with the planetary gear shaft hole (4) of lateral direction penetrating sphere inner chamber (1), the outer wall of differential casing horizontally outward extends to form spiral bevel gear setting circle (5), described spiral bevel gear setting circle (5) is provided with circumferentially uniform mounting hole, on described differential casing outer wall, just to the link position place of sphere inner chamber (1) with half axis hole (2), be provided with pair of bearings dismounting clamping short slot (6), and arrange in the axis bilateral symmetry of half axis hole (2), the inwall of differential casing is provided with just to the reinforced block of bearing removal clamping short slot (6), to avoid the differential casing wall thickness at bearing removal clamping short slot (6) present position place too thin.
2. differential casing according to claim 1, is characterized in that: the helix angle of described helix oil groove (3) is 45 degree.
