Description
Technical field
The utility model relates to a kind of transmission shaft, is specifically related to the deboost axle transmission device in a kind of harvester gear box.
Background technique
In harvester gear box, deboost axle is as lazy axle, and drive left and right driving wheel, be the reduction gearing mechanism of outbalance in harvester gear box simultaneously.The deboost axle driving mechanism of existing reaper is made up of transmission shaft, roller bearing, packing ring, combination needle bearing, left gear, hole back-up ring, right gear.The driving mechanism of first this structure needs mounting hole back-up ring, and the needle bearing of two band Internal and external cycles in tandem, assembling is difficulty comparatively; Next is that left gear utilizes needle bearing to carry out axially locating via hole back-up ring, and because needle bearing has Internal and external cycle, and hole back-up ring only located bearing outer ring, the easy play of inner ring.Locate unreliable and affect the needle bearing life-span.
Summary of the invention
The purpose of this utility model is the shortcoming that will overcome above-mentioned technology, provide that a kind of structure is simple, assembling easily, the deboost axle transmission device of good reliability.
Deboost axle transmission device of the present utility model, comprise transmission shaft, needle bearing, left gear, right gear, roller bearing, it is characterized in that: between described left gear and right gear, be provided with spacer in needle bearing spacer and transmission shaft, to left gear axially locating; Roller bearing spacer is provided with, to right gear axially locating between described right gear and roller bearing.
In order to better realize above-mentioned purpose:
Described needle bearing is with retainer, and the outer peripheral surface of transmission shaft and the inner peripheral surface of left gear are respectively the interior outer track of needle bearing.
The cylindrical interior step type spacer that described needle bearing spacer is made up of the first end face, the second end face and the 3rd end face, the first end face, the second end face and the 3rd end face touch with spacer in left gear, needle bearing and transmission shaft respectively.
Deboost axle transmission device of the present utility model, structure is simple, easy to manufacture, the outer peripheral surface of transmission shaft and the inner peripheral surface of left gear are respectively as outer track in the needle bearing of band retainer, bearing-free inner ring and bearing outer ring, needle bearing spacer is interior staircase structural model, play the double action of needle roller spacer and axial spacing deck simultaneously, simplify transmission structures and assembly process, reduce difficulty and the manufacturing expense of assembling, adopt needle bearing spacer, spacer and roller bearing spacer location in transmission shaft, avoid the axial stand under load of needle bearing, improve the reliability of transmission device and the stability of operation, effectively extend the working life of deboost axle transmission device, good economy performance.
