Abstract
The utility model relates to a differential shell and especially relates to a semi-spherical differential shell with an adjustable gap. The semi-spherical differential shell with the adjustable gap mainly solves technical problems of incapability of gap adjustment between a planet shaft gear and a half shaft gear of a present differential shell, relative low transmission accuracy of a planetary gear, relative high machining difficulty, uneasy assembly and disassembly and rather poor operating safety. The semi-spherical differential shell with adjustable gap comprises a shell body (1) and is characterized in that the shell body (1) is provided with a flange plate (2); an installing hole (3) is arranged on the flange plate; the inner of the shell body (1) is provided with a large aperture (6) in which a planet shaft gear (4) and a half shaft gear (5) can be installed; the shell and the half shaft gear are cooperated to form a spherical shape; and between the inner surface of the shell and the planet shaft gear is arranged a spherical gasket (7 ) adjusting speed.
Description
Technical field
The utility model relates to a kind of differential casing, especially relates to a kind of hemisphere type clearance adjustable type differential casing.
Background technique
Domestic car and other class automobile have substantially all adopted symmetric type bevel gear open differential at present.The symmetric type bevel differential is comprised of planetary pinion, planet pin (cross axle or a direct selling axle) and differential casing etc.Planet pin is arranged in the corresponding planet of differential casing hole, on the axle journal of differential mechanism two ends, overlaps sliding bearing is arranged respectively, and planetary pinion is housed in housing, and planetary pinion is assemblied on planet axis.The planet axis two ends are provided with jump-ring slot, with two jump rings, are stuck on differential casing planet outer end of hole face, prevent the planet axis axial float.Planetaryly each side with a straight-tooth circular cone differential gear, be meshed.The axle journal of differential gear is bearing in corresponding hole, differential casing left and right, its internal spline is connected with semiaxis, the differential gear that the planetary pinion rotated together with differential casing is stirred both sides rotates, when wheel suffered resistance in both sides is different, planetary pinion, also through around self axis, rotating a rotation, is realized the differential of both sides wheel is driven.But the gap of the planet axis gear of existing differential casing and differential gear can't be adjusted, and planetary transmission accuracy is lower, and difficulty of processing is higher, assembling and dismounting are comparatively difficult, and the Security of operation is poor.
The model utility content
The utility model is to provide a kind of hemisphere type clearance adjustable type differential casing, it is mainly that the planet axis gear of the existing differential casing of solution prior art and the gap of differential gear can't be adjusted, planetary transmission accuracy is lower, difficulty of processing is higher, assembling and dismounting are comparatively difficult, the technical problem of the poor grade of the Security of operation.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Hemisphere type clearance adjustable type differential casing of the present utility model, comprise housing, described housing is provided with flange plate, have mounting hole on flange plate, the inside of housing is provided with the large fenestra that planet axis gear and differential gear can be installed, housing and differential gear matching design spheroiding, be provided with speed governing ball-type packing ring between shell inner surface and planet axis gear.Housing and differential gear matching design spheroiding, optimized the mechanics configuration.Gap length between planet axis gear and differential gear can be adjusted according to speed governing ball-type packing ring, thereby has improved planetary transmission accuracy.
As preferably, the large fenestra edge of described housing is provided with the lubricant oil storage chamber.Can have lubricant oil in the lubricant oil storage chamber, thereby can be lubricated semiaxis.
As preferably, described housing is integrated casting, and more for convenience, intensity is stronger in processing like this.
Therefore, the utility model arranges speed governing ball-type packing ring between shell inner surface and planet axis gear, can adjust the gap length between planet axis gear and differential gear, thereby make planetary transmission accuracy higher, difficulty of processing is lower, assembling and dismounting are comparatively easy, fitting tight, the Security of operation is better, weight reduction, reduce component unnecessary, simple and reasonable for structure.
The accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Component, position and numbering in figure: housing 1, flange plate 2, mounting hole 3, planet axis gear 4, differential gear 5, large fenestra 6, speed governing ball-type packing ring 7, lubricant oil storage chamber 8.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the hemisphere type clearance adjustable type differential casing that this is routine, as Fig. 1, comprise housing 1, housing is provided with flange plate 2, have mounting hole 3 on flange plate, the inside of housing is provided with the large fenestra 6 that planet axis gear 4 and differential gear 5 can be installed, and housing and differential gear matching design spheroiding, be provided with speed governing ball-type packing ring 7 between shell inner surface and planet axis gear.Large fenestra 6 edges of housing are provided with lubricant oil storage chamber 8.Housing is integrated casting.
During use, driven by engine gearbox input shaft rotates, make inner each grade of gear rotate, drive the main reducing gear driven gear and rotate, thereby make the differential mechanism integral-rotation, in the differential casing rotary course, planetary pinion is simultaneously in rotation, planetary pinion rotarily drives the differential gear rotation, and the differential gear internal spline drives the tire Formation of Axle Shaft Spline, thereby realizes that power is passed to tire from motor.
The foregoing is only specific embodiment of the utility model, but structure characteristic of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification all are encompassed among the scope of the claims of the present utility model.
