Background
The wheel type forklift in the domestic engineering machinery industry often works under severe environments, particularly when forking and transporting large stones, the stones are heavy and overload forklift operation phenomenon is unavoidable, the path for forking and transporting the stones is long, and frequent alternate operation is performed continuously. The wheel type forklift drive axle wheel limit sun wheel and the half axle are commonly connected through spline fit, the other end spline of the half axle is connected with the inner half axle gear spline fit of the differential mechanism so as to transmit torque, the length of a drive axle of the forklift with medium and heavy tonnage is longer, the length of the half axle is also lengthened, the spline at the two ends of the half axle is easy to cause larger error in processing, the transmission error is increased, the play of the sun wheel is increased, the meshing gap between the sun wheel and the planet wheel is also changed, when the meshing gap reaches the limit stress value of the sun wheel, the sun wheel has the faults of pitting and tooth punching, the wheel edge of the drive axle is damaged, and the reliability and the service life of the drive axle are reduced.
Disclosure of Invention
The utility model aims to solve the defects, and provides a sun gear half shaft structure of a forklift drive axle, which has the advantages of simple and compact structure, low manufacturing and maintenance cost and reliable use, and solves the problems that in the prior art, due to the fact that the half shaft is too long, the machining precision deviation of splines at two ends of the half shaft is large, the movement amount of the sun gear becomes large, pitting and tooth striking occur, and finally the wheel edge of the drive axle is damaged.
In order to achieve the above purpose, the utility model relates to a fork loader drive axle sun gear half shaft structure, which comprises an end cover 1, a wheel edge speed reducer assembly 2, a half shaft 3, a wheel edge support shaft 4, a bridge shell 5, a main speed reducer assembly 6, a half shaft gear 7, a sun gear 8 and an adjusting support column 9; the wheel rim support shaft 4 and the axle housing 5 are welded together; the wheel-side speed reducer assembly 2 is sleeved into the wheel-side supporting shaft 4; the main speed reducer assembly 6 is arranged in the inner cavity of the axle housing, and a half-shaft gear in the main speed reducer assembly 6 is in spline fit connection with the shaft end of the half shaft 3; the sun gear 8 and the half shaft 3 are of an integral structure, and the integral sun gear and the wheel-side speed reducer assembly 2 carry out gear tooth meshing transmission; the adjusting support 9 is used for limiting the axial movement of the half shaft 3 so as to ensure the transmission efficiency.
Above-mentioned fork installation transaxle sun gear semi-axis structure is through making semi-axis and sun gear into monolithic structure, has following technical characteristics and beneficial effect:
1. the sun gear and the half shaft are of an integral structure, so that the problem of spline clearance of the sun gear is avoided, the shifting amount of the sun gear is greatly reduced, the meshing with the planetary gears at the wheel sides is smoother, the pitting and meshing faults of the tooth surfaces of the sun gear are avoided, and the service life and the reliability of the drive axle are greatly improved;
2. simple and compact structure, simple forging and processing technology and low manufacturing cost.
Drawings
FIG. 1 is a schematic diagram of the principal cross-sectional structure of the sun gear half shaft of the drive axle of the forklift of the present utility model.
Reference numerals: the wheel hub speed reducer comprises an end cover 1, a wheel hub speed reducer assembly 2, a half shaft 3, a wheel hub supporting shaft 4, an axle housing 5, a main speed reducer assembly 6, a half shaft gear 7, a sun gear 8 and an adjusting strut 9.
Detailed Description
The structure of the sun gear half shaft of the drive axle of the forklift loader is further described in detail below with reference to the accompanying drawings and the detailed description.
As shown in FIG. 1, the sun gear half shaft structure of the forklift drive axle comprises an end cover 1, a wheel-side speed reducer assembly 2, a half shaft 3, a wheel-side support shaft 4, a bridge shell 5, a main speed reducer assembly 6, a half shaft gear 7, a sun gear 8 and an adjusting strut 9; the wheel rim support shaft 4 and the axle housing 5 are welded together; the wheel-side speed reducer assembly 2 is sleeved into the wheel-side supporting shaft 4; the main speed reducer assembly 6 is arranged in the inner cavity of the axle housing, and a half-shaft gear in the main speed reducer assembly 6 is in spline fit connection with the shaft end of the half shaft 3; the sun gear 8 and the half shaft 3 are of an integral structure, and the integral sun gear and the wheel-side speed reducer assembly 2 carry out gear tooth meshing transmission; the adjusting support 9 is used for limiting the axial movement of the half shaft 3 so as to ensure the transmission efficiency.
When the fork loader works, the main speed reducer is transmitted to the sun gear half shaft to be connected through spline fit, and then is directly transmitted to the wheel side speed reducer assembly, the sun gear 8 and the half shaft 3 adopt an integral structure, at the moment, no spline fit clearance exists between the sun gear 8 and the half shaft 3, the shifting amount of the sun gear is greatly reduced, the meshing with the wheel side planet gears is smoother and smoother, the pitting and meshing faults of the tooth surfaces of the sun gear are avoided, the service life and the reliability of the drive axle are greatly improved, and the problems that in the prior art, due to the fact that the half shaft is too long, the machining precision deviation of the splines at two ends of the half shaft is large, the shifting amount of the sun gear is greatly pitted, tooth is formed, and finally the wheel side of the drive axle is damaged are solved.
