Abstract
A kind of gear shaft lubrication system, problem to be solved is using three gear needle bearing connections between the gear driving gear of gearbox three and input shaft, needle bearing can well reduce the coefficient of friction between gear and axle on set between input shaft and three gear driving gears, abrasion between bore and axle is smaller, plus needle bearing should be noted, oil groove design must be increased in gear face, the lubricating oil in speed changer is set to enter in needle bearing, but three gear driving gear processing oil grooves, increase process cost；The technical solution of the utility model is that three gear driving gears are provided with the input shaft of hierarchic structure, and three gear driving gear tops are provided with two gear driving gear, and needle bearing is provided between three gear driving gears and input shaft；The side of three gear driving gears is provided with annular boss, and annular boss cooperates with the spoke of two gear driving gear；The opposite side of three gear driving gears is provided with ring gear jig, and three gear ring gears are provided with the ring gear jig.
Description
Technical field：
The utility model is related to gear lubrication technical field, specifically a kind of gear lubricating structure.
Background technology：
Gearbox three is kept off using three gear needle bearing connections between driving gear and input shaft, in input shaft and three gear masters
The coefficient of friction that needle bearing can be reduced between gear and axle well, the abrasion between bore and axle are put between moving gear
It is smaller, plus needle bearing should be noted, it is necessary to increase oil groove design in gear face, the lubricating oil in speed changer is entered
In needle bearing, but three gear driving gear processing oil grooves, increase process cost, at the same processing oil groove to may result in section thick
Rugosity is bad, influences the durable and NVH performances of gearbox.
The content of the invention
The utility model provides a kind of gear lubricating structure.
What the purpose of this utility model was realized in：It includes:Input shaft, it is characterized in that：The input shaft of hierarchic structure
On be provided with three gear driving gears, three gear driving gears tops are provided with two gear driving gear, three gear driving gear and input shafts
Between be provided with needle bearing；The side of three gear driving gears is provided with annular boss, annular boss and two gear driving gear
Spoke cooperates；The opposite side of three gear driving gears is provided with ring gear jig, is provided with the ring gear jig
Three gear ring gears.
Two gear driving gear is arranged on input shaft stepped locations of the diameter of axle less than three gear driving gears, two gear driving gear
It is integrally formed with input shaft.
The utility model has the advantages that：The present invention is devised using input shaft two gear driving gear and three gear driving gears certainly
The structure that body structure is lubricated, it is not necessary to three gear driving gear processing oil grooves, reduces manufacturing procedure, production cost reduction；
Secondly, when being processed oil groove operation, if quality control is unqualified, may result in gear dynamic balancing bad and there is burr
Etc. phenomenon, this manufacturing procedure is reduced, it is to avoid above risk.The utility model also has simple structure, easy to operate, reliability high
The features such as.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the A portions enlarged drawing of Fig. 1.
Specific embodiment
Referring to Fig. 1, three gear driving gears 2 are provided with the input shaft 1 of hierarchic structure, three gear driving gear tops are provided with
Two gear driving gear 3, needle bearing 4 is provided between three gear driving gears and input shaft；The side of three gear driving gears is set
There is annular boss 5, annular boss cooperates with the spoke of two gear driving gear；The opposite side of three gear driving gears sets with teeth
Ring jig 6, is provided with three gear ring gears 7 on the ring gear jig.
Two gear driving gear is arranged on input shaft stepped locations of the diameter of axle less than three gear driving gears, two gear driving gear
It is integrally formed with input shaft.
Theory of mechanics
Novel input two gear driving gear and three gear driving gear structures include input shaft two gear driving gear and three gears
Driving gear.Two gear driving gear is fixed on input shaft, is together processed with input shaft.The side of three gear driving gears,
Having a boss with two grades of driving gear contact surfaces is used for and two grades of positioning of driving gear, the opposite side of three gear driving gears
Face, i.e., with three gear ring gear contact surfaces, leave platform for the welding with three gear ring gears, and three gear driving gears are pacified by needle bearing
On input shaft, the root diameter of the diameter of bore more than two gear driving gear of three gear driving gears.
The application method of speed changer tooth axle：
Input shaft two gear driving gear is fixed on input shaft, is together processed with input shaft, two gear driving gear root circle
Diameter is assemblied on input shaft less than three gear driving gear diameter of bores, three gear driving gears by three gear needle bearings, other
Gear and other mechanisms of speed changer are assembled into speed changer, during transmission duty is constituted, because input shaft two gear driving gear and three is kept off
Driving gear structure, the lubricating oil in gearbox can enter into the interior of three gear driving gears by the root circle of two gear driving gear
Kong Zhong, realizes the lubrication to needle bearing in the case of three gear driving gears and three gear needle bearings run at high speed.
