Abstract
The utility model relates to a radial positioning structure of an output revolving gear, comprising a small gear. The small gear is arranged on the output shaft of a transmission device through a spline pair, a shaft-end positioning baffle is fixed on the shaft head of the output shaft of the transmission device through bolts, both ends of the inner wall of the small gear are configured with two spigots, the spigot on one end is connected with a shaft step of the output shaft of the transmission device, the spigot on the other end is connected with the shaft-end positioning baffle of the output shaft of the transmission device, the two spigots play the role of radial positioning on the small gear, the splines connection between the small gear and the output shaft of the transmission device only plays the role of transmitting torque, and the splines are in clearance fit. The utility model has the advantages of reliable radial positioning of the small gear and uniform load distribution on tooth surface.
Description
Technical field
The utility model relates to a kind of output swiveling gear, is specifically related to a kind of output swiveling gear radial location structure.
Background technique
In typical gear drive application, the output axle head of gear drive is the spline shaft extension, the endoporus of a small gear is a splined hole, small gear is installed on the output shaft of transmission device by the spline endoporus, small gear adopts axle head baffle plate axially locating, rely on the tooth top or the flank radial location of spline, the outputting power of transmission device passes to small gear by splined, small gear and gearwheel or tooth bar engagement drive the gearwheel revolution or rely on the vehicle to run of the counter-force drive installation transmission device that tooth bar produces.In this design, the centering mode that splined adopts, no matter be flank centering, still tooth top is felt relieved, and all is difficult to guarantee the concentricity of small gear and gear drive output shaft, the load because small gear often withstands shocks in the course of the work possibly, can cause the splined of small gear and transmission device output shaft to occur loosening, swing can appear in small gear, causes flank of tooth load distribution unusual, even broken teeth.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the utility model provides a kind of output swiveling gear radial location structure, and it is reliable to have a small gear radial location, flank of tooth load distribution advantage of uniform.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of output swiveling gear radial location structure, comprise a small gear 1, small gear 1 is installed on the transmission device output shaft 2 by spline pair 3, axle head positioning baffle 5 is fixed on the spindle nose of transmission device output shaft 2 by bolt 6, the two ends of the inwall of small gear 1 dispose first seam 7 and second seam 8, the axle rank 4 of first seam 7 of one end and transmission device output shaft 2 join, and second seam 8 of the other end and the axle head positioning baffle 5 of transmission device output shaft 2 join.
Working principle of the present utility model is:
The two ends of the inwall of small gear 1 dispose two seams, two seams have played radial location to small gear 1, the splined of small gear 1 and transmission device output shaft 2 only need play the effect of transmitting torque, and the cooperation of spline is a Spielpassung, does not need drive fit.
Because small gear disposes two seams, two seams have played radial location to small gear, so it is reliable to have a small gear radial location, and flank of tooth load distribution advantage of uniform.

Fig. 2 is the sectional drawing of small gear 1 of the present utility model.
Embodiment
In the accompanying drawing: 1 is small gear; 2 is the transmission device output shaft; 3 is spline pair; 4 is the axle rank; 5 is the axle head positioning baffle; 6 is bolt, and 7 is first seam; 8 is second seam.
The utility model will be further described below in conjunction with accompanying drawing.
See figures.1.and.2, a kind of output swiveling gear radial location structure, comprise a small gear 1, small gear 1 is installed on the transmission device output shaft 2 by spline pair 3, axle head positioning baffle 5 is fixed on the spindle nose of transmission device output shaft 2 by bolt 6, axle head positioning baffle 5 and transmission device output shaft 2 are linked into an integrated entity, the two ends of the inwall of small gear 1 dispose first seam 7 and second seam 8, the axle rank 4 of first seam 7 of one end and transmission device output shaft 2 join, second seam 8 of the other end and the axle head positioning baffle 5 of transmission device output shaft 2 join, and make the cylndrical surface of small gear both sides all realize radial location.
Working principle of the present utility model is:
The two ends of the inwall of small gear 1 dispose two seams, match in the axle rank 4 of first seam 7 of one end and transmission device output shaft 2, second seam 8 of the other end and the axle head positioning baffle 5 of transmission device output shaft 2 match, axle head positioning baffle 5 is fixed on the spindle nose of transmission device output shaft 2 by bolt 6, axle head positioning baffle 5 and transmission device output shaft 2 are linked into an integrated entity, two seams make whole small gear 1 realize radial location on transmission device output shaft 2, small gear 1 has been played the centering effect, the splined of small gear 1 and transmission device output shaft 2 only need play the effect of transmitting torque, the cooperation of spline is a Spielpassung, does not need drive fit.
