Abstract
The utility model discloses a double oil film lubrication differential gear, which comprises a differential gear housing as well as a planetary gear and a cross shaft fixed on the differential gear housing. An oil inlet on a differential gear housing and an oil storage tank on the cross shaft are sealed through the double oil film lubrication differential gear, an oil guide passage is arranged on a right housing of the differential gear, and a copper liner bushing is arranged between the planetary gear and the cross shaft. Aimed at the structures of an oil inlet on a differential gear outer housing and an oil storage tank on a cross shaft of the traditional differential gear, where impurities are easiest to enter, the traditional differential gear lubrication theory of the prior art is changed, and seal treatment is conducted for the oil inlet on the differential outer housing and the oil storage tank on the cross shaft of the traditional differential gear, where impurities are easiest to enter, thereby effectively avoiding the impurities from entering the interior of the differential gear through lubricant, and avoiding the lubricant in the differential gear housing from being thrown out of the differential gear during the high-speed operation at the same time; and the oil guide passage is additionally arranged on the differential gear right housing, so that the lubricant can enter the interior of the differential gear through a clearance between a half shaft and the differential gear housing, so as to play the function of lubrication.
Description
Technical field
The utility model relates to a kind of differential mechanism, specifically relates to a kind of pair of film lubrication differential mechanism, belongs to mechanical field.
Background technique
At present, the form of domestic semitrailer market recessed formula axle shell assembly adopts connecting plate mostly, and an end of connecting plate is connected with spindle nose, the other end be connected spindle nose and connect, connect spindle nose and be connected with central siphon again, rely on spindle nose and the spacing formation drop formation that is connected the spindle nose matching hole on the connecting plate.This kind structure connecting plate is stressed bigger, is easy to lose efficacy, and is subjected to spindle nose and the influence that is connected spindle nose matching hole spacing and camshaft stand in addition, and drop structure can only be within the specific limits.Therefore, simple in structure, drop flexibly, the recessed formula supporting bridge of reliability advantages of higher will have the bigger market competitiveness.
The model utility content
Deficiency at the prior art existence, technical problem to be solved in the utility model is, provides that a kind of strong sealing, Safety performance are strong, greasy property prevents that by force, effectively impurity from entering two film lubrication differential mechanisms that differential mechanism inside prevents simultaneously that again lubricant oil is thrown out of in the shell when running up by lubricant oil.
For solving the problems of the technologies described above, the technological scheme that the utility model is taked is, a kind of pair of film lubrication differential mechanism, comprise differential casing and be fixed in planetary pinion and cross axle on the differential casing that the described pair of film lubrication differential mechanism sealed filler opening on the differential carrier and the oil storage tank on the cross axle; The right shell of described differential mechanism is provided with the Oil Guide passage; Be provided with copper bush between planetary pinion and the cross axle.
Optimize, above-mentioned pair of film lubrication differential mechanism, its Oil Guide passage are L type or T type.
The utility model changes present traditional differential mechanism lubrication principle, the differential mechanism shell filler opening that the most easily enters at traditional differential mechanism impurity, cross axle oil storage tank structure, differential mechanism shell filler opening and cross axle oil storage tank that commute causes impurity to enter have carried out the sealing processing, prevent that effectively impurity from entering differential mechanism inside by lubricant oil, prevent simultaneously that when running up lubricant oil is thrown out of differential mechanism in the shell, on differential right casing, increase the Oil Guide passage, make lubricant oil enter differential mechanism inside and play lubrication, farthest avoid impurity to enter by the gap between semiaxis and the difference shell; Simultaneously increase copper bush between planetary pinion and cross axle, make and form lubricant film between copper bush and cross axle and the planetary pinion respectively, promptly double-layer oil film makes between cross axle and planetary pinion endoporus and avoids taking place intermetallic direct friction, causes adhesion wear.And the utility model strengthened sealing, avoids impurity to enter and also avoids lubricant oil to be thrown out of differential mechanism simultaneously; The double-layer oil film that produces has strengthened lubricated safety coefficient.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of cross axle of the prior art;
Fig. 3 is the structural representation of cross axle of the present utility model.
Embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of pair of film lubrication differential mechanism of the utility model, comprise differential casing and be fixed in planetary pinion 1 and cross axle 2 on the differential casing that the described pair of film lubrication differential mechanism sealed filler opening on the differential carrier and the oil storage tank on the cross axle; The right shell of described differential mechanism is provided with Oil Guide passage 3; Be provided with copper bush 4 between planetary pinion 1 and the cross axle 2.Its Oil Guide passage is L type or T type.The utility model has been done closed processing for the structure of differential carrier, cross axle, increases copper bush simultaneously between cross axle and planetary pinion, forms double-layer oil film by control size, plays good lubrication.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
