Abstract
The utility model discloses a reduction gear inner gear axle sleeve, the axle sleeve includes the axle sleeve body be equipped with annular oil groove on the inner wall of axle sleeve body, still be equipped with the oil groove of crossing vertical oil groove and/or slope with annular oil groove at least one on axle sleeve body inner wall. This reduction gear internal gear axle sleeve is owing to adopt above-mentioned structure after, owing to still be equipped with at least one vertical oil groove crossing with annular oil groove andor the oil groove of slope on the gear axle sleeve inner wall, can make tens times's of increase of the lubricated oil mass that the bearing passes through, establish the oil film between intermediate gear and intermediate gear axle, make the bearing obtain effectual lubrication and cooling, and provide effectual lubrication and cooling to both sides thrust surface, thereby the biggest sustainable load-bearing of sliding bearing has been improved greatly, can guarantee the great moment of torsion of back power take-off output, can improve the life of back power take-off drive mechanism again, reduce cost of maintenance, improve work efficiency, and its manufacturability is good, and convenient to process.
Description
Technical field
The utility model relates to gear bush, is specifically related to a kind of retarder internal gear axle sleeve.
Background technique
Because it is little that sliding bearing has a noise, support force is big, the characteristics of good operating stability; The driving gear of retarder adopts sliding bearing more, and transmitting torque is big, the advantage of stable working because of helical gear has, so generally adopt the helical gear transmission; But helical gear transmission meeting produces huge rollover moment, and this makes the lubricated environment very severe of transmission shaft, the power taking system of gearing shaft; Owing to will satisfy good gear engagement; Can take less matching gap between gear and the gear shaft, make that like this lubricant oil of oilgear bearing is very little through amount, make to be difficult to set up oil film between intermediate gear and the intermediate gear shaft; Can increase lubricant oil in axial temperature gradient; Make that lubricant oil temperature when arriving the bearing both sides of bearing capacity maximum is very high, can not play lubrication, the high temperature grease that releases from the bearing play simultaneously can not satisfy the lubricated of gear both sides thrust surface; Thereby cause between intermediate gear and the intermediate gear shaft taking place bonding, reduced the maximum sustainable bearing load of sliding bearing.
The model utility content
The purpose of the utility model is to overcome the defective that exists in the existing technology, and a kind of intermediate gear axle sleeve is provided, and this gear uranium cover can make between intermediate gear and the intermediate gear shaft sets up oil film; Guarantee that bearing obtains enough lubricated and coolings, can guarantee the bigger moment of torsion of transmission shaft output, the working life that can improve back power taking driving mechanism again; Reduce maintenance cost; Increase work efficiency, and its good manufacturability, be convenient to processing.
For realizing above-mentioned purpose; The technological scheme of the utility model is a kind of retarder internal gear axle sleeve of design; Said axle sleeve comprises the axle sleeve body; On the inwall of said axle sleeve body, be provided with annular oil groove, it is characterized in that, on the axle sleeve inner body wall, also be provided with at least one vertical oil groove that intersect with annular oil groove and/or the oil groove of inclination.
Wherein, described longitudinal oil slot length is identical with axle sleeve body axial length.
Wherein, described vertical oil groove is the vertical bar shape.
Wherein, described vertical oil groove is curved shape.
Wherein, described annular oil groove roughly is positioned at the axle sleeve body shaft to the intermediate portion.
Wherein, the oil groove of said inclination is through the axial length of axle sleeve.
Wherein, the oil groove of said inclination shape in the shape of a spiral.
The advantage and the beneficial effect of the utility model are: this retarder internal gear axle sleeve is because after adopting said structure and since on the gear bush inwall, also be provided with at least one vertical oil groove of intersecting with annular oil groove with or the oil groove of inclination, can make the increase of tens times of lubricants capacities that bearing passes through; Between intermediate gear and intermediate gear shaft, set up oil film; Make bearing obtain effective lubricating and cooling, and effective lubricating and cooling are provided, thereby improved the maximum sustainable bearing load of sliding bearing greatly the both sides thrust surface; Can guarantee the bigger moment of torsion of back power taking output; Can improve the working life of back power taking driving mechanism again, reduce maintenance cost, increase work efficiency; And its good manufacturability is convenient to processing.
Description of drawings
Fig. 1 is the structural representation of the utility model retarder internal gear axle sleeve;
Fig. 2 is the user mode partial structurtes figure of the utility model retarder internal gear axle sleeve.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the embodiment of the utility model is further described.Following examples only are used for more clearly explaining the technological scheme of the utility model, and can not limit the protection domain of the utility model with this.
As shown in Figure 1, the utility model is a kind of retarder internal gear axle sleeve, and this gear bush comprises axle sleeve body 1; On axle sleeve body 1 inwall, be provided with annular oil groove 3, annular oil groove 3 roughly is positioned at axle sleeve body 1 axial intermediate portion, on axle sleeve body 1 inwall, also is provided with at least one vertical oil groove 2 that intersect with annular oil groove 3 and/or the oil groove 4 that tilts; Vertically oil groove 4 at least one ends of oil groove 2 and/or inclination extend to axle sleeve body 1 axial end portion; Vertically oil groove 4 length of oil groove 2 and/or inclination are preferably identical with axle sleeve body 1 axial length, and this vertical oil groove 2 and/or the oil groove 4 that tilts can be transported to the fuel feeding of bearing the two ends of bearing, and vertically oil groove 2 can be the vertical bar shape; With the axle sleeve parallel axes; Also can be curved shape, vertically oil groove 2 can have some, and cooling effect is better.The oil groove 4 that tilts can be the vertical bar shape, becomes certain included angle with the axle sleeve axis, also shape in the shape of a spiral, and the oil groove 4 of inclination can have some, and cooling effect is better.
Shown in Figure 2 is the structural representation of the utility model user mode, and among the figure, axle sleeve 1 and intermediate gear 5 link together through interference fit, then are Spielpassung between axle sleeve 1 and the intermediate gear shaft 5, and intermediate gear 6 can freely rotate around intermediate gear shaft 5.When work, lubricant oil flows out from the oilhole of intermediate gear shaft 5, and the annular oil groove 3 on the process axle sleeve 1 and vertical oil groove 2 come the thrust surface 7 of lubricative axle sleeve internal surface and gear both sides, simultaneously the heat that produces in the working procedure are taken away, to reach cooling purpose.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
