Description

Tractor gearbox self-lubricating system

Technical Field

The utility model relates to a tractor gearbox self-lubricating system.

Background

At present, the lubricating modes of the domestic tractor gearbox have two types: lubricating oil lubrication by means of rotation splashing of the gears inside the gearbox and lubricating oil lubrication by means of forced injection of the gear pump outside the gearbox are achieved, poor bearing lubrication at the upper end of an oil surface or on the inner side of a bearing port of the gearbox is easily caused by the lubricating oil lubrication mode by means of rotation splashing of the gears inside the gearbox, a tractor inclines to one side particularly in sloping field operation and under-shore plowing operation, lubricating oil is concentrated on the side, long-time oil shortage of the other side is caused, damage to bearings and gears is easily caused, and the service lives of the gears and the bearings in the gearbox are greatly prolonged. If this problem can be solved to the lubricated mode of the outside gear pump forced injection lubricating oil of gearbox, but the forced lubrication system need increase parts such as external pipeline, gear pump, filter, bypass valve, and the pipeline is longer, the interface is more moreover, arranges confusion, assembly loaded down with trivial details on the tractor, greatly increased manufacturing cost, be unfavorable for popularizing and applying.

Disclosure of Invention

An object of the utility model is to overcome above-mentioned shortcoming, the utility model provides a tractor gearbox self-lubricating system is provided, it has mainly been solved and has leaned on the rotatory lubricated mode of lubricating oil that splashes of the inside gear of gearbox easily to cause the inboard bearing lubrication of oil level upper end or gearbox bell mouth bad, the tractor is to a lopsidedness in the operation of sloping field operation and bank down plow very much, make lubricating oil concentrate on this side, lead to the long-time scarce oil of opposite side, cause bearing and gear damage easily, adopt the lubricated mode of gearbox outside gear pump forced injection lubricating oil to solve this problem, but forced lubrication system need increase external pipeline, the interface is more, arrange the confusion on the tractor, assemble loaded down with trivial details scheduling problem. The utility model aims at realizing the above, a tractor gearbox self-lubricating system is by: the oil seal device comprises a second shaft, a first bearing seat, a second bearing seat, an oil seal, a locking nut, a first conical bearing, a first transmission gear, a synchronizer, a second conical bearing, a third conical bearing, a lubricating oil pipe, a fourth conical bearing, a gearbox shell, a lubricating seat, a second transmission gear, a first shaft, a third transmission gear, an idler shaft bearing, an idler shaft and an oil outlet. The lubricating seat is installed on a gearbox shell, an oil outlet is formed in the lubricating seat, a second conical oil bearing, a first shaft, a second transmission gear, a synchronizer, a first transmission gear and a first conical bearing are sequentially sleeved on the gearbox shell, the first shaft and the first conical bearing are locked through a locking nut, the first conical bearing is fixed on the gearbox shell through a second bearing seat, a third transmission gear, an idler shaft bearing and an idler shaft are sequentially inserted on the gearbox shell, the third conical bearing, the second shaft and a fourth conical bearing are respectively sleeved on the gearbox shell, an oil seal is installed in the first bearing seat, the fourth conical bearing is fixed on the gearbox shell through the first bearing seat, and a lubricating oil pipe is installed on the lubricating seat. This product has adopted tractor gearbox self-lubricating system, simple structure, and reasonable in design, through the inside a pair of gear oil absorption of gearbox to pour into the lubricated mode at each position that the load is great, the position is not good into, promoted lubricated effect by a wide margin, prolonged the life on chassis, reduced the fault rate, arrange neatly on the tractor, the assembly is simple, has reduced manufacturing cost, is favorable to popularizing and applying.
