Description
Technical field
This utility model belongs to technical field of agricultural machinery, relates to a kind of farm machinery supporting wheel shaft, is particularly well-suited to harvester supporting wheel shaft.
Background technology
Several thrust wheel is installed in tracks of harvester, in each thrust wheel, is mounted on supporting wheel shaft, each supporting wheel shaft is provided with a pair ball bearing, in use, there is following defect:
One), for ensureing that bearing normally works, need often bearing to be dosed lubricious oils and fats, owing to bearing is positioned at thrust wheel, refuel extremely inconvenient；
Two), ball bearing bearing capacity is little, retainer is fragile, once damage, just can take off bearing after needing to dismantle crawler belt and thrust wheel, time-consuming take a lot of work, harvesting belongs to seasonal Work machine, to gather in 70～80 mu of crops every day, the economic loss that harvester user is caused by dismounting of stopping work is big, and for guaranteeing that bearing is gathering in season failsafe, equipment typically can be maintained in season by harvester user in each harvesting, No. 3～4 bearings are changed in every annual meeting, therefore maintenance cost is high；
Three), when using in paddy field, owing to paddy field is uneven, operating mode is severe, and wheel shaft impact is big, easy bending, fractures, and easily gathers mud, wheel shaft easy-to-rust in axis hole, and wheel shaft is difficult to dismantle after bending or corrosion.
Summary of the invention
The purpose of this utility model to solve above-mentioned technical problem.
The purpose of this utility model is achieved in that a kind of farm machinery supporting wheel shaft, including axle, it is characterized in that: described axle is five sections of multidiameters, five sections of multidiameters are from left to right followed successively by big end, bearing section, slotted line, thread segment, small end, double-row roller bearing it is provided with on bearing section, the inside right-hand member of double-row roller bearing is provided with oil sealing, the left side of oil sealing is provided with circlip for hole, the right-hand member outer ring of bearing section is provided with circlip groove, being provided with circlip for shaft on circlip groove, circlip for shaft is positioned at the right-hand member of double-row roller bearing；The outer ring of slotted line is provided with the most uniform several groove；The big end of multidiameter is provided centrally with the centre bore communicated with bearing section, is provided with lubricating oil in centre bore, and the left end of big end centre bore is provided with grease nipple；Slotted line outer ring is from left to right disposed with back-up ring, O RunddichtringO, the hole of frame；Thread segment outer ring is from left to right disposed with rubber plain cushion, plain cushion, spring washer, nut, box nut.
It is provided with through hole between described axle bearing section centre bore and the external cylindrical surface of bearing section, the inner ring of double-row roller bearing is provided with the through hole that the external cylindrical surface with bearing section communicates.
This utility model is rational in infrastructure, and without dismantling thrust wheel during oiling, wheel shaft is readily disassembled, and mud is not easily accessible bearing, and popularization and application have good economic and social benefit.
