Abstract
The utility model discloses a transmission structure of a drive axle shaft of a self-propelled combine harvester, and belongs to the field of agricultural machinery and equipment. The transmission structure comprises the axle shaft and an axle tube welded member which is sleeved on the axle shaft, wherein a first tapered roller bearing and a second tapered roller bearing are respectively mounted on axle shafts at two ends of the axle tube welded member; and a axle shaft gear on one side of the first tapered roller bearing is arranged on the axle shaft through a gear seat. Compared with the prior art, the transmission structure has the advantages that the problem that conventional bearings can't bear large axial force and are prone to failure is effectively solved, the problem that cone bearings utilized for the conventional structure can't be adjusted is effectively solved, and difficulties in assembling and inconvenient in repairing are effectively overcome.
Description
Technical field
The utility model relates to the agricultural machinery equipment field, specifically a kind of self-propelled combine half shaft drive mechanism.
Background technology
Along with improving constantly of rice machine yield, rice harvester has had fast development.Rice combine half shaft drive mechanism generally adopts the mode that passes eventually gear wheel (monoblock type) and two cylinder roller bearing transmissions on the market.The problem that this structure exists is: 1) axle bearing bears very large axial force, and is bad easily; Can't adjust when 2) original structure uses cone bearing; Relatively more difficult when 3) passing eventually the gear wheel assembling, the semiaxis maintenance difficult.
Summary of the invention
Technical assignment of the present utility model is for above weak point, and the self-propelled combine half shaft drive mechanism of a kind of rational in infrastructure, easy installation and removal, long service life is provided.
The technical scheme that its technical problem that solves the utility model adopts is: this half axis transmission structure comprises semiaxis and is enclosed within bridge tube soldering member on the semiaxis, is separately installed with taper roll bearing one and taper roll bearing two on the semiaxis at bridge tube soldering member two ends; The axle shaft gear of taper roll bearing one side is installed on the semiaxis by pinion stand.
The end of described axle shaft gear side semiaxis is equipped with locking nut.
A kind of self-propelled combine half shaft drive mechanism of the present utility model is compared with existing technology, and has following characteristics:
1) two back-to-back installations of taper roll bearing efficiently solve original bearing and can not bear the very fault of the easy bad bearing of larger axial force;
2) by adjusting the gap of locking nut adjustment taper roll bearing, efficiently solve the problem that original structure uses cone bearing to adjust;
3) will pass eventually gear wheel and make split-type structural into, efficiently solve assembling difficulty and the inconvenient problem of maintenance.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing is the structural representation of self-propelled combine half shaft drive mechanism.
Among the figure: 1, locking nut, 2, pinion stand, 3, axle shaft gear, 4, taper roll bearing one, 5, taper roll bearing two, 6, semiaxis, 7, the bridge tube soldering member.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Self-propelled combine half shaft drive mechanism of the present utility model, its structure comprise semiaxis 6 and are enclosed within bridge tube soldering member 7 on the semiaxis 6, be separately installed with taper roll bearing 1 and taper roll bearing 25 on the semiaxis 6 at bridge tube soldering member 7 two ends; The axle shaft gear 3 of taper roll bearing one 4 sides is installed on the semiaxis 6 by pinion stand 2; The end of axle shaft gear 3 side semiaxis 6 is equipped with locking nut 1.
Its processing and fabricating of self-propelled combine half shaft drive mechanism of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except the described technical characterictic of specification, be the known technology of those skilled in the art.
