Abstract
The utility model discloses a rear power take-off device lubricating structure for an engine. The technical scheme is that: the rear power take-off device lubricating structure for the engine comprises an oil duct formed in a cylinder body of the engine; the oil duct is communicated with one end of a flywheel casing oil duct formed in a flywheel casing through a hollow elastic pin; the other end of the flywheel casing oil duct is communicated with a small oil hole in a rear power take-off shell; the small oil hole leads to a bearing of an inner cavity of the rear power take-off shell; the inner cavity of the rear power take-off shell is communicated with a gear chamber in the rear end of the engine; and a rear power take-off oil seal and a rear power take-off oil seal bushing block are arranged in a rear power take-off flange which is connected with the rear power take-off shell. The utility model has the beneficial effects that: the rear power take-off device lubricating structure for the engine is simple in structure and convenient to use; and by the rational design of the rear power take-off device lubricating structure for the engine, the lubricating capability of a rear power take-off device can be improved.
Description
Technical field
The utility model 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 utility model provides a kind of simple in structure, easy to use to the deficiency of existing technology, through the appropriate design to power takeoff lubricating structure behind the motor, to improve the lubricating ability of back power takeoff.
The utility model is realized 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.
The concrete characteristics of the utility model 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.
The beneficial effect of the utility model is: through directly utilizing the lubricant oil of engine cylinder oil duct; And employing 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.

Among the figure, 1, cylinder block, 2, flywheel casing, 3, hollow resilient key, 4, back power taking housing, 5, the O RunddichtringO, 6, back power taking flange, 7, back power taking oil sealing, 8, oil duct, 9, the flywheel casing oil duct, 10, little oilhole, 11, back power taking oil sealing lining.
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 utility model 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 the restriction to the utility model, and the utility model also is not limited in above-mentioned giving an example; Variation, remodeling, interpolation or replacement that those skilled in the art are made in the essential scope of the utility model also should belong to the protection domain of the utility model.
