Abstract
The utility model relates to an anti-backflow structure for lubricating oil in an oil hole of a gear shaft of a tractor, which comprises a lubricating oil spraying connector, a bearing cover, an oil hole blocking ring, a gear shaft, a cylindrical bearing, a sliding bearing and a gear. The oil hole blocking ring is pressed in the oil hole of the gear shaft through interference. The bearing cover is fixed on a gearbox shell of the tractor through a bolt, the lubricating oil spraying connector is screwed on the bearing cover through threads, and the oil pipe of the lubricating oil spraying connector extends deep into the oil hole of the gear shaft. The gear is smoothly sleeved on the sliding bearing, the sliding bearing is sleeved on the gear shaft through a spline sleeve, and the gear shaft is supported on the cylindrical bearing. The structure is convenient to install. When the structure is installed, the oil hole blocking ring is directly pressed into the oil hole on the gear shaft through interference. Due to blockage of the oil hole blocking ring, the lubricating oil is accumulated in the oil hole of the gear shaft and can be effectively prevented from flowing back, the lubrication of the sliding bearing on the gear shaft can be guaranteed, and the operating reliability of the gear mechanism of the transmission system of the tractor can be improved.
Description
Technical field
The utility model belongs to the tractor field, relates to lubricant oil anti-backflow structure in a kind of used with tractor gear shaft oilhole.
Background technique
At present, in the forced lubrication structure of the power train of the large and middle tractor configuration of domestic production, the gear shaft oilhole is generally a straight hole, though it is simple in structure, easily manufactured, the phenomenon that refluxes away from axle head can appear but work the time sprays into lubricant oil in the oilhole, enter the required lubricant oil deficiency of the sliding bearing of suit on the gear shaft thereby cause, can't form desirable lubricant film, thereby the sliding bearing heating appears, and then cause sliding bearing and gear generation scuffing, cause gear mechanism to damage in early days.Therefore, it is necessary fully designing the interior lubricant oil anti-backflow structure of a kind of used with tractor gear shaft oilhole.
The model utility content
It is a kind of simple in structure, easy for installation that the purpose of this utility model is to provide, and can effectively prevent to enter the interior lubricant oil anti-backflow structure of used with tractor gear shaft oilhole that the lubricant oil in the gear shaft oilhole refluxes.
The utility model can reach above-mentioned effect by the following technical programs, and lubricant oil anti-backflow structure in the used with tractor gear shaft oilhole comprises: lubricant oil oil spout joint, bearing cap, oilhole back-up ring, gear shaft, cylindrical bearing, sliding bearing, gear; The interference of oilhole back-up ring is pressed in the oilhole of gear shaft; Bearing cap is by being bolted on the gear box of tractor housing, and on bearing cap, the oil pipe of lubricant oil oil spout joint is deep in the oilhole of gear shaft lubricant oil oil spout joint by the screw thread spinning.
Gear shaft is supported on the cylindrical bearing, by spline housing sliding bearing is housed on the gear shaft, and gear is smooth to be sleeved on the sliding bearing.
The utility model can reach following beneficial effect after adopting technique scheme: lubricant oil anti-backflow structure in this used with tractor gear shaft oilhole, install very convenient, during installation the direct interference of oilhole back-up ring is pressed in the oilhole on the gear shaft and gets final product, by stopping of oilhole back-up ring, lubricant oil will be accumulated in the gear shaft oilhole, can prevent effectively that the lubricant oil that enters in the gear shaft oilhole from refluxing away, guarantee the lubrication effect of the sliding bearing on the gear shaft, improve Tractor Power Train gear mechanism reliability of operation.
Description of drawings
Accompanying drawing is a lubricant oil anti-backflow structural representation in the utility model used with tractor gear shaft oilhole.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.As shown in drawings, lubricant oil anti-backflow structure in the used with tractor gear shaft oilhole comprises: lubricant oil oil spout joint 1, bearing cap 2, oilhole back-up ring 3, gear shaft 4, cylindrical bearing 5, sliding bearing 6, gear 7.Oilhole back-up ring 3 is an interference fit with gear shaft 4 oilhole inwalls, and 3 interference of oilhole back-up ring are pressed in gear shaft 4 oilholes, makes oilhole back-up ring 3 with gear shaft 4 rotations.Bearing cap 2 is by being bolted on the gear box of tractor housing, lubricant oil oil spout joint 1 passes through the screw thread spinning on bearing cap 2, the oil pipe of lubricant oil oil spout joint 1 is deep in the oilhole of gear shaft 4, gear 7 smooth being sleeved on the sliding bearing 6, on gear shaft 4, gear shaft 4 is supported on the cylindrical bearing 5 sliding bearing 6 by spline package.
During work, lubricant oil sprays in gear shaft 4 oilholes from lubricant oil oil spout joint 1, when lubricant oil is back to gear shaft 4 oilhole end face outlet, by stopping of oilhole back-up ring 3, can prevent effectively that the lubricant oil that enters in the gear shaft oilhole from refluxing away, lubricant oil will be accumulated in the oilhole of gear shaft 4, be carved with enough lubricant oil under the effect of the rotary centrifugal force of gear shaft 4 in the time of then can guaranteeing in the oilhole of gear shaft 4, enter the junction plane X place of sliding bearing 6 and gear 7 by the thin oilhole Y on the running shaft, form desirable lubricant film, prevent that the sliding bearing heating from causing the generation of sliding bearing and gear generation scuffing, thereby guaranteed the lubrication effect of the sliding bearing on the gear shaft, improved Tractor Power Train gear mechanism reliability of operation.
