[0001] The utility model relates to gear technology field especially relates to gearbox output shaft gear. BACKGROUND
[0002] In the vehicle, gearbox belongs to important mechanical parts, is used for controlling the advance or retreat and the speed size of vehicle, and the output shaft is the shaft that is connected with the drive shaft in the gearbox, sets up the gear on the output shaft, transmits through the gear mutual meshing, realizes power output. The output shaft gear will cause the gear impact and the wear and tear and damage of the gear in addition to due to normal wear, because lubrication condition is bad.
[0003] To solve this problem, the utility model thus produces. CONTENT
[0004] Therefore, in view of the above problems, the utility model provides a gearbox output shaft gear which has simple structure and good lubrication effect.
[0005] To solve the above technical problem, the utility model adopts the following solution: the gearbox output shaft gear includes a fixed shaft, an output shaft, and a gear arranged on the output shaft, an oil inlet chamber is formed in the gear, an oil outlet channel is formed on the gear teeth, the oil outlet channel is in communication with the oil inlet chamber, an oil inlet channel is formed in the gear, the oil inlet channel is in communication with the oil inlet chamber, and a lubricating oil extrusion and injection device is arranged in the oil inlet chamber.
[0006] Further improvement is that the injection device includes an extrusion plate, a sliding rod is slidably arranged in the gear, one end of the sliding rod is located in the oil inlet chamber, the other end of the sliding rod penetrates the gear and can push the sliding rod to slide when the gears mesh with each other, the extrusion plate is arranged on the sliding rod, and a reset device is arranged in the gear and can automatically reset after the sliding rod slides.
[0007] Further improvement is that the reset device includes a reset plate, a reset channel is formed in the gear, the sliding rod is located in the reset channel, the reset plate is arranged on the sliding rod and located in the reset channel, and a reset member is arranged in the reset channel.
[0008] Further improvement is that the reset member is a reset spring, the reset spring is sleeved on the sliding rod, one end of the reset spring abuts against the reset plate, and the other end of the reset spring abuts against the inner wall of the reset channel.
[0009] Further improvement is that the oil inlet channel is provided with an oil inlet check valve, and the oil outlet channel is provided with an oil outlet check valve.
[0010] By adopting the foregoing technical scheme, the utility model has the advantages of:
[0011] The gear structure is simple and has good lubricating effect. When the gear rotates and engages, lubricating oil is sprayed from the oil outlet channel, so that the gears can be better lubricated, the impact between the gears is reduced, the wear and damage between the gears are reduced, and the service life of the gear is prolonged. BRIEF DESCRIPTION OF DRAWINGS
[0012] Fig. 1 is a schematic diagram of a gearbox output shaft gear structure according to an embodiment of the present application.
[0013] Fig. 2 is a schematic diagram of a gearbox output shaft gear structure according to an embodiment of the present application. DETAILED DESCRIPTION
[0014] The present application will be further described in conjunction with the drawings and specific embodiments.
[0015] REFERENCE Figs. 1-2 The present application discloses a gearbox output shaft gear, which comprises an output shaft 11 and a gear 1 arranged on the output shaft 11. An oil inlet chamber 2 is arranged in the gear 1. An oil outlet channel 3 is arranged on the gear teeth and the gear groove of the gear 1. The oil outlet channel 3 is in communication with the oil inlet chamber 2. An oil inlet channel 9 is arranged on the gear 1 and is in communication with the oil inlet chamber 2. A lubricating oil spraying device is arranged in the oil inlet chamber 2.
[0016] Specifically, the lubricating oil spraying device comprises an extrusion plate 4 and a return plate 6. A sliding rod 5 is slidably arranged on the gear 1. One end of the sliding rod 5 is located in the oil inlet chamber 2, and the other end of the sliding rod 5 penetrates the gear 1 and can push the sliding rod 5 to slide when the gears 1 engage with each other. The extrusion plate 4 is arranged on the sliding rod 5. A return channel is arranged in the gear 1. The sliding rod 5 is located in the return channel. The return plate 6 is arranged on the sliding rod 5 and located in the return channel. A return spring 7 is arranged in the return channel. The return spring 7 is sleeved on the sliding rod 5. One end of the return spring 7 abuts against the return plate 6, and the other end of the return spring 7 abuts against the inner wall of the return channel.
