Abstract
The invention provides a lubricating structure of an engine rear power take-off device. The invention adopts the technical scheme that the lubricating structure of the engine rear power take-off device comprises an oil pipe arranged on a gas cylinder body of an engine, the oil pipe is communicated with one end of a flywheel shell oil pipe arranged on a flywheel shell through a hollow elastic pin, the other end of the flywheel shell oil pipe is communicated with a small oil hole on a rear power take-off shell, the small oil hole is communicated with a bearing in a cavity of the rear power take-off shell, the cavity of the rear power take-off shell is communicated with a gear chamber at the rear end of the engine, and a rear power take-off oil seal and a rear power take-off lining bushing are arranged in a rear power take-off flange connected with the rear power take-off shell. The lubricating structure provided by the invention has the beneficial effects of simple structure and convenience for use. Through the reasonable design of the lubricating structure of the engine rear power take-off device, the lubricating capability of the rear power take-off device can be improved.
Description
Technical field
The present invention is a power takeoff lubricating structure behind a kind of motor.
Background technique
In engine torque extraction device when design,, some Lubrication Design adopts external pipeline, and the lubricant oil of the engine cylinder-body connecting pipeline through the motor outside is incorporated into lubricant oil moving elements such as back power taking housing lubricating bearings.There are shortcomings such as leakage of oil, easy abrasion in external pipeline, and has increased pipe resistance, causes whole back power takeoff faulty lubrication, and parts wear quickens, and shortens its working life.
Summary of the invention
The present invention is directed to the deficiency of existing technology, provide a kind of simple in structure, easy to use, through appropriate design, to improve the lubricating ability of back power takeoff power takeoff lubricating structure behind the motor.
The present invention realizes through following technical measures: comprise the oil duct that is arranged on the engine cylinder; Said oil duct is communicated with flywheel casing oil duct one end on being arranged on flywheel casing through hollow resilient key; The other end of said flywheel casing oil duct is communicated with little oilhole on the power taking housing of back; Said little oilhole leads to back power taking housing inner chamber; Said back power taking housing inner chamber is communicated with motor rear end gear chamber, be provided with in the back power taking flange that said back power taking housing is connected after the power taking oil sealing and after power taking oil sealing lining.
Concrete characteristics of the present invention also have, and in the both sides of said little oilhole, are provided with the O RunddichtringO between back power taking housing and the flywheel casing.
Above-mentioned back power taking oil sealing is an outside framework oil seal.
Beneficial effect of the present invention is: through directly utilizing the lubricant oil of engine cylinder oil duct, and adopt the effective seal structure, make the back power takeoff obtain abundant effective lubricating, reduce the wearing and tearing of movement parts, the working life of having improved back power takeoff.

Embodiment
For clearly demonstrating the technical characterstic of this programme, through an embodiment, this programme is set forth below.
Shown in accompanying drawing; Power takeoff lubricating structure behind a kind of motor comprises the oil duct 8 that is arranged on the engine cylinder 1, and said oil duct 8 is communicated with flywheel casing oil duct 9 one ends on being arranged on flywheel casing 2 through hollow resilient key 3; The other end of said flywheel casing oil duct 9 is communicated with little oilhole 10 on the back power taking housing 4; Said little oilhole 10 leads to back power taking housing 4 inner chambers, and the bearing in the lubricated back power taking housing, and said back power taking housing 4 inner chambers are communicated with motor rear end gear chamber; Lubricant oil is together got back to oil sump; Be provided with back power taking oil sealing 7 and the oil sealing of power taking afterwards lining 11 in the back power taking flange 6 that said back power taking housing 4 is connected, in the both sides of said little oilhole 10, be provided with O RunddichtringO 5 between back power taking housing 4 and the flywheel casing 2; Like this with seal oil in the cavity of back power taking housing, prevent that oil leakage from arriving back power taking output terminal.Wherein back power taking oil sealing 7 is an outside framework oil seal.
The present invention can pass through or adopt existing techniques in realizing without the technical characteristics of describing; Repeat no more at this; Certainly, above-mentioned explanation is not to be limitation of the present invention, and the present invention also is not limited in above-mentioned giving an example; Variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present invention also should belong to protection scope of the present invention.
Claims (3)
1. power takeoff lubricating structure behind the motor; It is characterized in that; Comprise the oil duct that is arranged on the engine cylinder; Said oil duct is communicated with flywheel casing oil duct one end on being arranged on flywheel casing through hollow resilient key, and the other end of said flywheel casing oil duct is communicated with little oilhole on the back power taking housing, and said little oilhole leads to the housing of power taking afterwards inner chamber; Said back power taking housing inner chamber is communicated with motor rear end gear chamber, be provided with in the back power taking flange that said back power taking housing is connected after the power taking oil sealing and after power taking oil sealing lining.
2. power takeoff lubricating structure behind the motor according to claim 1 is characterized in that, in the both sides of said little oilhole, is provided with the O RunddichtringO between back power taking housing and the flywheel casing.
