Abstract
The invention relates to a seal structure of an engine timing chamber cover plate. The seal structure comprises a cover plate body, and is characterized in that a locating platform is arranged on one side of the cover plate body; the connection part between the locating platform and the cover plate body is provided with an annular groove; an O-shaped seal ring is arranged in the annular groove; and a cover plate mounting through hole is formed in a circumferential direction on the outer side of the annular groove. By adopting the technical scheme, a timing chamber power output end seal structure is promoted, the service life is prolonged, the sealing effect is good, and the cost performance is excellent; and the problem of engine oil leakage of a timing chamber power output end of a tractor on the market is solved.
Description
Technical field
The invention belongs to engine timing room cover plate technical field, more particularly to a kind of engine timing chamber cover plate for sealing
Structure.
Background technology
At present, the timing room clutch end of electromotor is sealed by cover plate and shim form.But the use longevity of pad
Life is shorter, is affected greatly by factors such as ambient temperature, service conditions, tractor occurs leakage machine at multiple sealing during marketing efforts
The bad phenomenon of oil, the sealing knot for ensureing electromotor serviceability and extending its service life, to timing room clutch end
Structure carries out lifting design.
Content of the invention
The present invention for solve known technology present in technical problem and provide a kind of long service life, good sealing effect,
Excellent cost performance, solve the problems, such as the engine timing chamber cover plate for sealing of tractor timing room clutch end lubricating oil leakage on market
Structure.
The present invention is adopted the technical scheme that by solving technical problem present in known technology：
A kind of engine timing chamber cover plate for sealing structure, including cover board body it is characterised in that：The one of described cover board body
Side is provided with positioning table, and the junction of described positioning table and cover board body is provided with annular groove, is provided with O-shaped in described annular groove
Sealing ring, is provided with cover plate installing hole through hole in the outer circumference direction of annular groove.
The present invention can also adopt following technical measures：
Compression surplus 20%～30% when described O-ring seal is installed.
Loading in annular groove for the described O-ring seal is 65%～90%.
The present invention has the advantages and positive effects that：Because the present invention adopts technique scheme, lifting timing room moves
Power output end sealing structure, extend service life, good sealing effect, excellent cost performance the advantages of；It is dilatory on market to solve
The problem of machine timing room clutch end lubricating oil leakage.
Brief description
Fig. 1 is the structural representation of the present invention；
Fig. 2 is A-A sectional view in Fig. 1.
In figure：1st, cover board body；1-1, positioning table；1-2, annular groove；1-3, hole through hole；2nd, O-ring seal.
Specific embodiment
For content of the invention, feature and effect of the present invention can be further appreciated that, hereby enumerate following examples, and coordinate accompanying drawing
Describe in detail as follows：
A kind of engine timing chamber cover plate for sealing structure, including cover board body 1, the side of described cover board body is provided with positioning
Platform 1-1, the junction of described positioning table and cover board body is provided with annular groove 1-2, is provided with O-shaped sealing in described annular groove
Circle 2, is provided with cover plate installing hole through hole 1-3 in the outer circumference direction of annular groove.
The present invention can also adopt following technical measures：
Compression surplus 20%～30% when described O-ring seal is installed.
Loading in annular groove for the described O-ring seal is 65%～90%.
The present invention has the advantages and positive effects that：Because the present invention adopts technique scheme, lifting timing room moves
Power output end sealing structure, extend service life, good sealing effect, excellent cost performance the advantages of；It is dilatory on market to solve
The problem of machine timing room clutch end lubricating oil leakage.In order to reach better seal effect, timing room cover plate straight mouth size is root
Based on timing room outfan diameter, and O-ring need to compress surplus (20%～30%) and loading when actually used
(65%～90%) is designed and type selecting.
The above is only to presently preferred embodiments of the present invention, not the present invention is made with any pro forma restriction,
Every technical spirit according to the present invention, to any simple modification made for any of the above embodiments, equivalent variations and modification, belongs to
In the range of technical solution of the present invention.
