Notch, the thickness of gasket are adapted to the height of positioning convex platform；Gasket adaptation on the end face of inspection hole cover.
The gear-box inspection hole cover sealing structure of this programme design, gasket is covered on the end face of inspection hole cover.Window
The end face of lid is designed to the positioning convex platform that is equipped with of regularity, and corresponding position is equipped with location hole or locating notch on gasket,
The thickness of gasket is adapted to the height of positioning convex platform.When gasket is covered on inspection hole cover end face, location hole, locating notch
It is just socketed with positioning convex platform, screw hole is then passed through by bolt, inspection hole cover is fastened on gear box, at this time gasket
By the pressure of the end face of inspection hole cover, sealing effect is formed.Under this structure, gasket is laterally by location hole, fixed
The limit of position notch and positioning convex platform, will not occur sidesway, ensure that in the case where gearbox body external and internal pressure difference is larger according to
Displacement will not be so deformed, still has good sealing effect.
Preferably, screw hole is located on the quadrangle and side of inspection hole cover；The positioning convex platform includes screw hole boss；Screw hole is convex
The cross sectional shape of platform is isosceles triangle；Screw hole boss positioned at the quadrangle of inspection hole cover, screw hole are located at the bottom edge of isosceles triangle
Midpoint, the vertex of isosceles triangle are flushed with the side wall corner of inspection hole cover；Screw hole boss positioned at the side of inspection hole cover, screw hole position
In the vertex of isosceles triangle, the bottom edge of isosceles triangle is flushed with the side wall of inspection hole cover；Corresponding, gasket is equipped with screw hole
Boss locating notch is adapted to screw hole boss.This programme by screw hole design on the quadrangle and side of inspection hole cover, and every
All it is the screw hole boss that cross sectional shape there are one designs is isosceles triangle on the position of a screw hole, and not according to screw hole
The layout of same position, screw hole boss is also variant：When on angle, the vertex of screw hole boss is located at outside, the side with inspection hole cover
Wall corner flushes, and screw hole is set to isosceles triangle bottom edge midpoint；When on side, the vertex of screw hole boss is located inside, i.e.,
The position of screw hole, and the bottom edge of isosceles triangle is flushed with the side wall of inspection hole cover.It designs in this way, can further strengthen convex
Platform to the limit effect of gasket, meanwhile, each screw hole boss is all the position that bolt passes through fastening, and the upper surface of boss is direct
It is close to fix with the lower surface of gear case body, excessively the gasket near bolt will not be caused to be overly compressed because of fastening and led
Mutagens shape and seal failure.
Preferably, the positioning convex platform includes the long boss being symmetrically arranged on two opposite side of inspection hole cover end face；It is long
The cross sectional shape of boss is rectangle, and length direction of the length direction along place side extends；Corresponding, it is convex that gasket is equipped with length
Platform location hole is adapted to long boss.Length direction of the length direction of long boss along inspection hole cover side extends, can be further strong
Change the compartment displacement position-limiting effect to gasket.
Preferably, four angles of the cross sectional shape of the long boss are circular arc chamfering, it is corresponding, long boss location hole
Four angles of cross sectional shape are also circular arc chamfering.Design can reduce the scuffing to gasket and destroy in this way.
Preferably, the material of the gasket is nitrile rubber.Nitrile rubber have good water resistance, oil resistivity,
Air-tightness and excellent adhesive property are very suitable for use in gear-box etc. is containing oil environment.
Preferably, the material of the inspection hole cover is aluminium diecasting.Inspection hole cover is made using aluminium diecasting, makes inspection hole cover
End face is relatively soft, and certain deformation can be generated when stress fastens, is preferably adapted to each other with gasket, is formed more preferable
Sealing effect.
In conclusion the utility model has the beneficial effects that：More excellent sealing effect can be provided.
