Invention content
The present invention can increase torque-transfer capability and with limit function to overcome the deficiencies of the prior art and provide one kind
New work engine gasket.
To achieve these goals, the present invention uses following technical scheme：A kind of new work engine gasket, including gasket sheet
Body, the shim body be equipped with through-hole, the shim body include interlayer, set on the interlayer outer surface outer layer and be set on
Friction member on the outer layer.When the present invention is pressed between each gear member contact face of automobile engine crankshaft front end,
Since the surface of gasket outer layer is equipped with friction member, therefore increase the friction coefficient of shim body so that gasket is commonly used with bent axle
Alloy structure Steel material, belt pulley often with cast iron materials and sprocket wheel often with the friction coefficient of powdered metallurgical material reach 0.4 with
On；And then the frictional force increased between gasket and each contact face of high degree, and be to pass through frictional force between each gear member
Torque is transmitted, so that about 3 times of torque-transfer capability increase of gasket or more.
Further, the shim body is equipped with limiting section；When automobile timing chain wheel is equipped with positioning key, by padding
On piece is set and the matched limiting section of positioning key so that gasket can be stablized is connected on the end face of timing sprocket, it is therefore prevented that
Mutually rotation occurs between gasket and timing sprocket.
Further, the limiting section is the groove on the through-hole wall；By on groove and timing sprocket
Positioning key coordinates, and can be connected to what gasket was stablized on timing sprocket.
Further, the shim body external peripheral surface is with being equipped with protrusion at groove opposite position；Due to groove
In the presence of the intensity for reducing shim body, therefore protrusion is equipped at shim body external peripheral surface and groove opposite position, it can be more
Shim body is mended because of strength deterioration caused by groove setting.
Further, the interlayer is spring steel layer；Spring steel has high tensile strength, elastic limit and high fatigue
Intensity, therefore suitable for being used under shock and vibration or long-term friendship stress, extend the service life of gasket.
Further, the outer layer is nickel alloy layer；Nickel-containing alloys have high-wearing feature, further extend making for gasket
Use the service life.
Further, the friction member is diamond particle；In the diamond coated particle of superficies, since diamond is micro-
Kernel structure is special, and the height of each diamond particle is not consistent after coating, therefore increases the degree of roughness of superficies so that pad
Piece often often uses the friction system of powdered metallurgical material with bent axle alloys in common use structure steel material, belt pulley with cast iron materials and sprocket wheel
Number reaches more than 0.4, and high degree increases frictional force；Meanwhile also by about 3 times of the torque-transfer capability increase of gasket or with
On, the performance that torque transmits is more preferable；And diamond particle hardness is big, is not easy to be worn, and ensure that gasket has permanent use
Service life；Meanwhile it because of diamond particle distribution character, will not be protected because there is lubricating oil torque transmission capacity to be caused to decline when flowing into mating surface
The performance for demonstrate,proving gasket is stablized.
In conclusion the present invention has the following advantages：Pass through the setting of friction member so that gasket and bent axle alloys in common use knot
Structure Steel material, belt pulley often often reach more than 0.4 with cast iron materials and sprocket wheel with the friction coefficient of powdered metallurgical material, greatly
The frictional force increased between gasket and each contact face of degree；Simultaneously so that about 3 times of the torque-transfer capability increase of gasket
Or more, the performance that torque transmits is more preferable.
