Embodiment
Do to illustrate in detail, intactly further to the utility model below in conjunction with mode of execution and accompanying drawing.
As Figure 1-3, the automobile-used gear-box of new gear structure comprises input shaft b1, described input shaft b1 is provided with one-level initiatively cylindrical gears b2, described one-level initiatively cylindrical gears b2 engages the passive cylindrical gears b3 of one-level, described one-level passive cylindrical gears b3 and planet wheel b5 is coaxially arranged on secondary drive shaft b4, described secondary drive shaft b4 is also provided with the first axle spring b41 regulating axial clearance, described planet wheel b5 is also meshed with gear ring b6, described gear ring b6 and three grade of active cylindrical gears b8 is coaxially arranged on three grades of transmission shaft b7, described three grades of active cylindrical gears b8 engage three grades of passive cylindrical gears b9, described three grades of passive cylindrical gears b9 are arranged on output shaft b10, described output shaft b10 is also provided with the second axle spring b11 regulating axial clearance,
Described one-level initiatively cylindrical gears b2, one-level passive cylindrical gears b3, three grades of actives cylindrical gears b8 and three grade of passive cylindrical gears b9 is new gear structure, new gear structure comprises gear 1, center hole 2, the gear teeth 3, teeth groove 4 and at least one lubrication channel 5, center hole 2 is in the center of gear 1, the gear teeth 3 are arranged in gear 1, a teeth groove 4 is formed between every two adjacent teeth 3, lubrication channel 5 is arranged in gear 1, by lubrication channel 5, the lubricant oil outside gear is imported gear internal.In new gear, the quantity of lubrication channel 5 is consistent with the quantity of teeth groove 4, the corresponding teeth groove 4 of each lubrication channel 5.New automobile gear comprises two keyholes 6 further, keyhole 6 to be arranged in gear 1 and to be communicated with center hole 2, two keyholes 6 are about the Central Symmetry of gear 1, when automobile gear coaxial inner conductor is arranged on axle, key is in keyhole 6 and axle, and when the lubricant oil outside gear is imported gear internal by lubrication channel 5, lubricant oil flows in keyhole 6, make the side of key form oil film, reduce wear.
Lubrication channel 5 comprises a lubrication oiler 51, and lubricates oil outlet 52 and a barrier element 53, lubrication oiler 51 is arranged on bottom teeth groove 4, lubrication oil outlet 52 is communicated with center hole 2, barrier element 53 is between lubrication oiler 51 and lubrication oil outlet 52, controls the circulation status of lubricant oil in lubrication channel 5 by barrier element 53.When barrier element 53 is open, lubrication oiler 51 is communicated with lubrication oil outlet 52, and lubricant oil can flow in lubrication oil outlet 52 by selflubricating oiler; When barrier element 53 is closed, lubrication oiler 51 and lubrication oil outlet 52 non-interconnected.
Barrier element 53 comprises three barrier sheets 531, three barrier sheets 531 are 120 degree of distributions around the center line of barrier element 53, the gross area of three barrier sheets 531 is greater than the total open area of barrier element 53, the area of every sheet barrier sheet 531 exceedes 1/3 of the total open area of barrier element 53, the barrier sheet of such barrier element 53 can only open in the direction along lubrication oiler 51 to lubrication oil outlet 52, such lubricant oil can only flow to lubrication oil outlet 52 from lubrication oiler 51, thus gear internal is lubricated, and prevent the lubricant oil of gear internal from overflowing.Barrier element 53 adopts elastic material to make, and the barrier sheet 531 simultaneously in barrier element 53 adopts elastic material to make.
Lubricant oil is at the flow process of new automobile gear, and for a lubrication channel 5, in the rotary course of this new automobile gear, the experience lubrication oiler 51 that this lubrication channel 5 can go round and begin again is upward to lubrication oiler 51 state down.When gear rotate to lubrication oiler 51 super upper time, lubricant oil in lubrication oiler 51 flows from lubricating oiler 51 toward lubrication oil outlet 52 direction, when lubricating oil flow is to barrier element 53, lubricant oil concentrates on barrier sheet 531, and the gravitational force urges barrier sheet 531 of lubricant oil opens to lubrication oil outlet 52 direction, the barrier sheet 531 of such barrier element 53 opens, barrier element 53 is opened, and lubricant oil, through barrier element 53, flows to lubrication oil outlet 52, enter gear internal, as shown in Figure 4 A, gear continuation rotates, and when rotating to lubricating (such as level) when oiler 51 is in upward non-or non-state down, the barrier sheet 531 of retaining piece 53 does not have lubricant oil, and barrier sheet 531 is due to its own resilient reset, and whole retaining piece 53 closes, when gear rotate to lubrication oiler 51 down time, the lubricant oil of gear internal flows backward to lubrication oil outlet 52, be back to the barrier sheet 531 of barrier element 53 from lubrication oil outlet 52, because in barrier element 53, the summation of barrier sheet 531 area exceedes the opening area of whole barrier element 53, lubrication pressure is on barrier sheet 531, barrier sheet 531 receives resistance each other, barrier sheet 531 can not lubricate oiler 51 direction mutually and open, such barrier element 53 is kept closed, lubricant oil can not pass barrier element 53, lubricant oil can not from lubrication oil outlet 52 to the flowing of lubrication oiler 51 direction, as shown in Figure 4 B.
This new gear structure is lubricated by the mode of immersion lubrication or splash lubrication, keeps the oil film between working gear face, reduces gear wear; This new automobile gear is arranged on axle by key coaxial line, and key makes the transmission of gear be passed to axle, thus when gear rotates, axle and gear synchronous rotate.
Finally be necessary described herein: above embodiment is only for being described in more detail the technical solution of the utility model; can not be interpreted as the restriction to the utility model protection domain, some nonessential improvement that those skilled in the art makes according to foregoing of the present utility model and adjustment all belong to protection domain of the present utility model.
