Abstract
The utility model discloses a planetary gear thrust washer of adaptable automobile -used high rotational speed operating mode demand, including circle body (1), angles such as circle body (1) upper surface are equipped with a plurality of cycle grooves, the cycle groove be by set up the radial sharp rectangle of circle body (1) upper surface inside and outside lead to groove (2) with set up leading to inside and outside the radial sharp rectangle groove (2) one side and with radial sharp rectangle inside and outside lead to groove (2) adjacent platform district (3) two parts constitution. The beneficial effects of the utility model are that, can produce fluid dynamic pressure bearing capacity when having relative motion between thrust washer and planetary gear, make and realize the non -contact and reducing wear between the two, demand that can the high rotational speed operating mode of better adaptation.
Description
Technical field
The utility model relates to thrust washer to be improved, particularly a kind of planetary pinion thrust washer adapting to automobile-used high speed conditions demand.
Background technique
At present, the planetary pinion thrust washer wear phenomenon in automobile-used planet row is studied, find that wearing and tearing are because the axial force of planet wheel to thrust washer causes, and axial force increases along with the rising of rotating speed; During low speed, gasket wear is slight, and serious wear so that damage during high-speed overload.
Model utility content
The purpose of this utility model is to solve the problem, and devises a kind of planetary pinion thrust washer adapting to automobile-used high speed conditions demand.
Realizing above-mentioned purpose the technical solution of the utility model is, a kind of planetary pinion thrust washer adapting to automobile-used high speed conditions demand, comprise circle body 1, described circle body 1 upper surface equal angles is provided with multiple periodic slots, described periodic slots be by groove inside and outside the radial alignment rectangle being arranged on circle body 1 upper surface 2 and be arranged on groove 2 side inside and outside radial alignment rectangle and with radial alignment rectangle inside and outside adjacent platform district 3 two-part of groove 2 form.
Inside and outside described radial alignment rectangle, the quantity of groove 2 is 15 ~ 20.
The groove depth 50 ~ 100 μm of groove 2 inside and outside described radial alignment rectangle.
Inside and outside described radial alignment rectangle, groove 2 is equal with the central angle angle shared by platform district 3.
The planetary pinion thrust washer adapting to automobile-used high speed conditions demand utilizing the technical solution of the utility model to make, and have between planetary pinion during relative movement and can produce hydrodynamic oil film bearing capacity, make realize non-contact therebetween and reduce wear, and, rotating speed higher hydrodynamic oil film bearing capacity is larger, can better the higher planet wheel shaft of balancing speed to the larger characteristic of power.The processing of radial alignment rectangle groove is than being easier to, and cost of production is lower; Face Flow Field on Radial Groove is because of the symmetry properties of structure, and having can the characteristic of positive and negative rotation, can adapt to the drive characteristic of comprehensive transmission; In addition, radial inside and outside groove can promote the flowing of lubricant oil and the thermolysis that increases part.
Accompanying drawing explanation
Fig. 1 is the structural representation adapting to the planetary pinion thrust washer of automobile-used high speed conditions demand described in the utility model;
In figure, 1, circle body; 2, groove inside and outside straight line rectangle; 3, Tai Qu.
Embodiment
Below in conjunction with accompanying drawing, the utility model is specifically described, if Fig. 1 is the structural representation adapting to the planetary pinion thrust washer of automobile-used high speed conditions demand described in the utility model, as shown in the figure, a kind of planetary pinion thrust washer adapting to automobile-used high speed conditions demand, comprise circle body 1, described circle body 1 upper surface equal angles is provided with multiple periodic slots, described periodic slots be by the inside and outside groove of the radial alignment rectangle (being not limited to rectangle) being arranged on circle body 1 upper surface 2 and be arranged on groove 2 side inside and outside radial alignment rectangle and with radial alignment rectangle inside and outside adjacent platform district 3 two-part of groove 2 form, inside and outside described radial alignment rectangle, the quantity of groove 2 is 15 ~ 20, inside and outside described radial alignment rectangle, the groove depth of groove 2 is 50 ~ 100 μm, inside and outside described radial alignment rectangle, groove 2 is equal with the central angle angle shared by platform district 3.
The feature of the technical program is, described circle body surface equal angles is provided with multiple periodic slots, described periodic slots be by groove inside and outside the radial alignment rectangle being arranged on circle body surface and be arranged on groove side inside and outside radial alignment rectangle and with radial alignment rectangle inside and outside the adjacent platform district two-part of groove form.Have between thrust washer and planetary pinion during relative movement and can produce hydrodynamic oil film bearing capacity, make realize non-contact therebetween and reduce wear, and rotating speed higher hydrodynamic oil film bearing capacity is larger, can preferably the higher planet wheel shaft of balancing speed to the larger characteristic of power.Inside and outside groove structure can promote that lubricating oil flow is to the thermolysis of part.
In the technical program, when groove number is about 20, oil film possesses maximum bearing capacity, and when groove number is in 10 ~ 60 scopes, oil film possesses larger bearing capacity, considers cost of production, should select less oil groove quantity, and suggestion groove number is chosen 15 ~ 20; When groove district is equal with central angle shared by platform district, oil film possesses best bearing capacity; Under the condition of physical dimension license, for obtaining larger oil film bearing capacity, packing ring radial dimension should be made large as much as possible; When groove depth > 50 μm, bearing capacity reduces, the working depth that suggestion design is larger, object is the wear extent reserving running-in period, good hydrodynamic lubrication can be obtained during to make normally to work, the structural factor that flow of lubrication can be made to increase has: increase oil groove quantity, increase the oil groove degree of depth, increase circle body radial width, wherein oil groove quantity and the oil groove degree of depth larger to flow effect.Increase gasket groove number, increase radial width, be conducive to reducing temperature rise; When groove depth is between 10 ~ 40 μm, temperature rise level is lower.
Technique scheme only embodies the optimal technical scheme of technical solutions of the utility model; those skilled in the art all embody principle of the present utility model to some variations that wherein some part may be made, and belong within protection domain of the present utility model.
