Abstract
The invention belongs to the technical field of machinery, and relates to a power divider device for changing two-wheel drive to four-wheel drive of a tractor. The power divider device mainly comprises a shell and two end bearing covers thereof; a spline shaft in the shell is supported between the two end bearing covers through a tapered roller bearing, and is provided with a sliding gear and a spiral bevel gear; a spiral bevel gear shaft matched with the spiral bevel gear is supported by the tapered roller bearing and fixed on the shell through a bearing block; and one end of the spiral bevel gear shaft is connected with an output flange. The device has simple, reliable and easily operated structure, low noise and long service life.
Description
Technical field: the invention belongs to field of mechanical technique, be specifically related to a kind of walker tractor is become four wheel drive by two-wheel drive power divider device that is used for.
Background technology: four-wheel drive tractor is a dark horse on agricultural machinery market at present, and the trend that replaces two-wheel drive trac. and track type tractor is arranged.
Four-wheel drive tractor traction adhesion value better, have advantages such as manoevreability preferably, higher hillside fields job stabilization and crossing ability.
But four-wheel drive tractor is in the market compared with the two-wheel drive trac., and at first its structure does not have the two-wheel drive trac. convenient than two-wheel drive trac. complexity at aspects such as adjustment, use, maintenances; Secondly, the initial cost of four-wheel drive tractor is higher, causes added burden to the user.
Summary of the invention: purpose of the present invention is exactly in order to address the above problem, and provides a kind of improved, simple in structure, reliable, easy to operate, cheaply four-wheel drive power divider device for tractor.
Technical solution of the present invention: mainly comprise housing and bearings at both ends thereof lid, its characteristics be castellated shaft in the housing by bearings between the bearings at both ends lid, castellated shaft is provided with cliding gear and finishing bevel gear cuter, the bevel gear shaft that matches with finishing bevel gear cuter is fixed on the housing by bearings and by bearing seat, and an end of bevel gear shaft is connected with the output flange.
General, the present invention is provided with the regulating ring and the set screw of adjustable bearings endplay in the outer end of bearing; The housing of part-time case adopts the steel casting that reinforced rib is arranged, and outside is welded with the trailer adaptor union, and housing adopts No. 20 cast steels to satisfy good welding performance (also can adopt cast steel No. 45, trailer adaptor union and housing form integral body); Described bearing is a tapered roller bearing; Described finishing bevel gear cuter is curved tooth or straight-tooth.
The preferred forms of finishing bevel gear cuter of the present invention and bevel gear shaft profile of tooth has all adopted the curved tooth structure, so this device has characteristics such as low noise, high service life.
Tapered roller bearing is adopted in castellated shaft of the present invention and bevel gear shaft supporting, can bear the suffered axial force of finishing bevel gear cuter by actv., obtains bigger raising service life.
Bearing endplay of the present invention adopts regulating ring and screw adjusted, has advantages such as easy to adjust, reliable.
Description of drawings: accompanying drawing 1 is the cross-sectional view of embodiment of the invention part-time case.
In the accompanying drawing, the 1-housing; The 2-bearing cap shim; The 3-cone bearing; The 4-cliding gear; The 5-castellated shaft; The 6-spiral bevel gear; The 7-regulating ring; The 8-screw; 9-spiral bevel gear axle; The 10-bearing seat; The 11-tapered roller bearing; The 12-holding screw; 13-exports flange.
The specific embodiment: the present invention is described in detail below in conjunction with embodiment and accompanying drawing:
Embodiment: present embodiment as shown in Figure 1, mainly comprise housing 1 and bearings at both ends thereof lid 2, castellated shaft 5 in the housing 1 is supported between the bearings at both ends lid 2 by cone bearing 3, castellated shaft 5 is provided with cliding gear 4 and spiral bevel gear 6, the spiral bevel gear axle 9 that matches with spiral bevel gear 6 supports and is fixed on the housing 1 through holding screw 12 by bearing seat 10 by tapered roller bearing 11, and an end of spiral bevel gear axle 9 is connected with output flange 13.
The outer end of the cone bearing 3 of present embodiment is provided with the regulating ring 7 and the set screw 8 of adjustable bearings endplay; Housing 1 is for there being the steel casting of reinforced rib.
The present embodiment device is connected with gear box of tractor, power imports into this device by cliding gear 4 from gear box of tractor and (by cliding gear 4 power is reached castellated shaft 5, by castellated shaft 5 power is reached spiral bevel gear 6, by spiral bevel gear 6 power is reached spiral bevel gear axle 9 again, realize the change of power direction by spiral bevel gear 6 and spiral bevel gear axle 9), pass to trailing wheel by spiral bevel gear axle 9 in this device by output flange 13, universal joint and drive shaft again, thereby realize the four wheel drive of trac..
The present invention can be installed the trailer adaptor union additional, with convenient compartment and the trailer of connecting.
Transfer gear of the present invention has following advantage:
(1) simple in structure, reliable, easy to operate, low noise, high service life.
(2) by increasing cost seldom, just can make the two-wheel drive tractor when keeping original two-wheel drive tractor primary structure and characteristics, possess many superiority of four-wheel drive tractor.
(3) thoroughly solve the shortcoming that two-wheel drive tractor heavy duty front-wheel skids, obviously improved the climbing capacity of car load, reduced the wearing and tearing of tire, especially be fit to the hauling operation of Rural Areas at Present road conditions difference and mountain area, hills and swampy area.
Claims (5)
1. four-wheel drive power divider device for tractor, mainly comprise housing and bearings at both ends thereof lid, it is characterized in that castellated shaft in the housing by bearings between the bearings at both ends lid, castellated shaft is provided with cliding gear and finishing bevel gear cuter, the bevel gear shaft that matches with finishing bevel gear cuter is fixed on the housing by bearings and by bearing seat, and an end of bevel gear shaft is connected with the output flange.
