Background technique
The wheeled tractor of four-wheel drive, the power of its motor is by the input shaft of clutch transmits to gearbox, export back axle to after the speed stage of gearbox and the torque adjustment, by final drive assembly power is reached rear wheel again, simultaneously the gear on the central transmission drive bevel gear axle in back is imported, export front drive axle to and drive front wheel through the transfer case speed change again, and performance tractive force, thereby the various functions of realization tractor.Front drive axle mainly comprises preceding central transmission, differential mechanism and side speed reducer structure, the meshed bevel gears of central transmission is through differential mechanism before power reaches, reach live axle after slowing down by the both sides reducing gear again and drive front-wheel, but between the limit decelerating casing of side speed reducer structure and the vertical shaft sleeve pipe thrust-bearing and lining are installed, connect as axial by thrust-bearing, lining is as radially connecting, because force of sliding friction is big, transmission efficiency is low, and the installing and locating precision is low, and is easy to wear, causes the sealing reliability of side speed reducer structure poor, thereby make seal failure, the rate of fault height.
Summary of the invention
The purpose of this utility model provides a kind of friction little, and sealing is reliable, can reduce the side speed reducer structure of the wheeled tractor front drive axle of fault.
The utility model is that the technological scheme that achieves the above object is: a kind of side speed reducer structure of wheeled tractor front drive axle, comprise the vertical shaft sleeve pipe, the limit decelerating casing, the limit deceleration driving gear, vertical shaft and limit deceleration driven gear and driving shaft-cup, the limit decelerating casing is bearing on the vertical shaft sleeve pipe by bearing, driving shaft-cup is installed on the decelerating casing of limit, the intermediate reduction gear driven gear and the limit deceleration driving gear that are installed on the vertical shaft are bearing on vertical shaft sleeve pipe and the limit decelerating casing by bearing respectively, live axle is bearing in by bearing respectively and drives on shaft-cup and the limit decelerating casing, be installed in limit deceleration driven gear and the engagement of limit deceleration driving gear on the live axle, it is characterized in that: described vertical shaft sleeve pipe periphery wall be provided with stepped shape on, step, the limit decelerating casing also be provided with corresponding stepped shape on, the lower bearing hole, last rolling bearing and following rolling bearing be installed in respectively the vertical shaft sleeve pipe on, on step and the limit decelerating casing, in the lower bearing hole, and anti-muddy water oil sealing is installed between limit decelerating casing and the vertical shaft sleeve pipe, and anti-muddy water oil sealing withstands on the shaft shoulder of vertical shaft sleeve pipe and goes up on the outer ring of rolling bearing.
Wherein: anti-muddy water oil sealing is installed between the shaft shoulder of described driving shaft-cup and the live axle, and anti-muddy water oil sealing withstands on an end of bearing.
Be connected with following rolling bearing by last rolling bearing respectively between the vertical shaft sleeve pipe of the utility model side speed reducer structure and the limit decelerating casing, because of the vertical shaft sleeve pipe all is rolling friction with the axial of limit decelerating casing with radially being connected, can significantly reduce the force of sliding friction of side speed reducer structure, improve the transmission efficiency of side speed reducer structure.The utility model is provided with the upper and lower bearing support of stepped shape on the periphery of vertical shaft sleeve pipe, and the limit decelerating casing is provided with the upper and lower bearing hole of stepped shape, the precision and the reliability of the installation of vertical shaft sleeve pipe and limit decelerating casing have been improved, because the opening of limit decelerating casing is equipped with anti-muddy water oil sealing, it is reliable to connect sealing, can reduce the rate of breakdown of side speed reducer structure greatly, therefore adopt the wheeled tractor of the utility model front drive axle structure, can be used for the operation of abominable working environments such as paddy field.
