Abstract
The utility model discloses a middle gear lubricating structure, which comprises a middle gear and a bush arranged in a middle gear hole. The inner side of the bush is provided with an annular oil groove, which is substantially positioned at the axial middle part of the bush; the internal surface of the middle gear is provided with at least one longitudinal oil groove; oil holes communicating with the longitudinal oil groove are arranged in the annular oil groove of the gear bush. The length of the longitudinal oil groove is equal to the axial length of the middle gear, and the longitudinal oil groove can be in the shape of a straight strip or be bent. The lubricating structure can increase the amount of the lubricating oil passing between the middle gear and the middle gear shaft to ensure that the lubricating oil is fully cooled, thereby not only guaranteeing large torque output of post power, but also improving the service life of the post power take-off, lowering the maintenance cost and increasing the working efficiency. In addition, the gear bush has excellent manufacturability and is easy to process.
Description
Technical field
The utility model relates to a kind of intermediate gear lubricating structure, particularly a kind of intermediate gear Sump lubrication structure that is used for power taking behind the motor.
Background technique
Back power taking output on the motor is to drive intermediate gear by crankshaft gear, and intermediate gear realizes for transmission of power the back power take-off gear again.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, the lubricated environment very severe of power taking axle system after this makes, very easily take place bondingly between intermediate gear and the intermediate gear shaft, reduced the maximum sustainable bearing load of sliding bearing.Power taking system after gear-driven in addition, owing to will satisfy good gear engagement, can take less matching gap between gear and the gear shaft, make that like this lubricant oil throughput of oilgear bearing is very little, 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 can not satisfy the lubricated of gear both sides thrust surface simultaneously.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of intermediate gear lubricating structure, this lubricating structure can make the lubricants capacity that passes through between intermediate gear and the intermediate gear shaft increase, guarantee the enough coolings of lubricant oil, 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.
For solving the problems of the technologies described above, the utility model comprises intermediate gear and the axle sleeve that is installed in the intermediate gear hole, the axle sleeve inboard is provided with annular oil groove, its structural feature is to be provided with at least one longitudinal oil groove on the intermediate gear internal surface of hole, is provided with the oilhole that is communicated with vertical oil groove in the annular oil groove of axle sleeve.
Described longitudinal oil slot length is identical with the axial length of intermediate gear, and vertically oil groove can be the vertical bar shape, also can be curved shape.
Described annular oil groove roughly is positioned at the axial intermediate portion of axle sleeve.
After adopting said structure, owing to be provided with the vertical oil groove that is communicated with annular oil groove on the axle sleeve on the intermediate gear internal surface of hole, the lubricants capacity that passes through between intermediate gear and the intermediate gear shaft is increased, guarantee the enough coolings of lubricant oil, can guarantee the bigger moment of torsion of back power taking 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.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model.
Embodiment
With reference to accompanying drawing, this intermediate gear lubricating structure comprises intermediate gear 1 and the axle sleeve 2 that is installed in the intermediate gear hole, axle sleeve 2 inboards are provided with annular oil groove 3, annular oil groove 3 roughly is positioned at axle sleeve 2 axial intermediate portions, on the intermediate gear internal surface of hole, be provided with at least one longitudinal oil groove 5, be provided with the oilhole 4 that is communicated with vertical oil groove 5 in the annular oil groove 3 of axle sleeve 2.Vertically oil groove 5 length are identical with intermediate gear 1 axial length, and vertically oil groove 5 can have some, and cooling effect is better like this, and vertically oil groove 5 can be the vertical bar shape, with the axle sleeve parallel axes, also can be curved shape.The quantity of oilhole 4 can have several, and corresponding with the bar number of vertical oil groove 5.When work, lubricant oil is through the annular oil groove 3 on the axle sleeve 2, between gear bush 2 and intermediate gear shaft, set up oil film to reach lubricated purpose, lubricant oil is by the vertical oil groove 5 on the 4 arrival intermediate gears of the oilhole on the axle sleeve 2 simultaneously, arrive gear both sides thrust surface by vertical oil groove 5, to reach lubricated and cooling purpose.
