Abstract

The utility model relates to an oil seal stop which can prevent the oil seal of a single-cylinder diesel engine crankshaft leaking oil, and the utility model can also reduce cost consumption and extend the service life of machines. The utility model is characterized in that an oil seal stop 7 is circular, and the inner diameter is provided with a flanging oil return slot. The outer diameter is provided with an oil return slot opening, the oil seal stop 7 is arranged at the outer side of a crankshaft neck 4 and at the inner side of an oil seal 9.

Description

Oil catch

The utility model belongs to lubricated field, is a kind of oil catch that increases in the single cylinder diesel lubricating system specifically.

At present, the one-cylinder diesel machine crankshaft is a spheroidal graphite cast iron, does not have oil catch or spiral oil-return groove on the crankshaft designs, can't adjust bush gap, and the oil pump in the work still uses same pressure at press oil, is that envelope does not live with oil sealing, can only let alone continuous expansion.Simultaneously, single cylinder diesel substantially all is the power of laterally borrowing, bent axle is after work a period of time, and the gap increases, because of bent axle is to lean against bearing shell on one side, especially through a series of processes such as overcompression, acting, exhausts, make bent axle depart from the cylinder body axis, form the inclined to one side under tile of bent axle, on one side corresponding order increases the gap, give machine oil one path, form leakage of oil.

The purpose of this utility model then is the problem at above-mentioned existence, and a kind of oil shelves that prevent the leakage of oil of single cylinder diesel crank shaft oil seal are provided.

The utility model technical solution:

A kind of oil catch that is used on the single cylinder diesel is characterized in that oil shelves 7 for circular, and internal diameter is provided with the flange oil-return groove, has the oil return notch on the external diameter, and oil catch 7 is positioned at the outside of crankshaft journal 4, the inboard of oil sealing 9.

Advantage of the present utility model:

The utility model can prevent the crank shaft oil seal leakage of oil, keeps environmental hygiene, reduces cost consumption, and prolongs the single cylinder diesel life-span, improves the quality of products.

Fig. 1 is the utility model assembling schematic representation.

Fig. 2 is the utility model oil catch plan view.

Fig. 3 is the utility model oil catch side view.

Below in conjunction with accompanying drawing the utility model is further described.

Oil shelves 7 are positioned at the outside of crankshaft journal 4, the inboard of oil sealing 9, oil sealing sealing spring 8 is connected on the inboard of oil sealing 9, have bush seat oil duct 6 on the bent bush seat 10, bush seat oil duct 6 is connected with crankshaft oil gallery 5, the oil duct of crankshaft oil gallery 5 extends to little watt of axle journal by crankshaft journal 3, the internal surface of the surface of crankshaft journal 4 and bearing shell 1 produces lubrication friction, provides lubricant oil by the bearing shell oil groove 2 that has on the bearing shell 1.

Claims

1. an oil catch that is used on the single cylinder diesel is characterized in that oil catch 7 for circular, and internal diameter is provided with the flange oil-return groove, has the oil return notch on the external diameter, and oil catch 7 is positioned at the outside of crankshaft journal 4, the inboard of oil sealing 9.
