Description
Technical field
The utility model relates to gasket seal field, particularly a kind of motor combined type pad.
Background technique
The metallic shim of motor is usually as the material of enhanced leaktightness between two planes, and the seal element revealed as preventing lubricating oil tank is arranged between static seal face.Metal current pad mostly is simple ring-type, after component contact to be sealed, can not form sealing strip, easily Seepage occur, and needs perfect further.The occasion often working environment more complicated that gasket seal is used, as on engine flange, the vibration that machine work is brought, fastening piece vibration on flange can be driven, cause the inwall of sealing gasket sector-meeting to flange below fastening piece and the surface to fastening piece cause shearing stress and have the trend of slip, cause contact position serious wear, this situation not only can cause the damage to individual parts, sealing place gap also can be made to become large, and then reduction seal effect greatly.
Model utility content
Goal of the invention of the present utility model is: for above-mentioned Problems existing, provides a kind of motor combined type pad, mainly solves the problem of sealing difference when two planes connect, solves the problem that gasket seal, fastening piece and contact surface abrasion are serious simultaneously.
The technical solution adopted in the utility model is as follows: a kind of motor combined type pad, comprise metallic shim body, described metallic shim body is provided with some casing bores and mounting hole, seal ring is inlaid with in described casing bore, described seal ring comprises rubber sleeve, first elasitic layer, second elasitic layer and stretchable layer, seal ring is connected by the first elasitic layer with casing bore inwall, the bonding described stretchable layer in another side of described first elasitic layer, bonding described second elasitic layer in another side of described stretchable layer, the another side adhesive rubber cover of described second elasitic layer, described rubber sleeve exposes the top and bottom of metallic shim body and forms shirt rim to turning up, the outer surface of rubber sleeve has a polytetrafluoroethylene floor, described stretchable layer is provided with some flanges, described each flange equidistant parallel is arranged on metallic shim body, and the gap location between each flange is groove, described flange and groove combination form waveform, or formation profile of tooth.
Further, described first elasitic layer is nitrile butadiene rubber layer or is acrylate rubber layer, width is 1-8mm, thickness is identical with the thickness of described metallic shim body, flange is provided with in the bi-side of the first elasitic layer, the groove having some to be parallel to each other is dug in the side of described metallic shim inner body wall, the fit depressions of the described flange of the first elasitic layer one side and the side of described metallic shim inner body wall, and be fixedly connected with by the mode of spraying and adhesive bonding agent, some the grooves be parallel to each other also are dug in the bi-side of described stretchable layer, match with the flange of described first elasitic layer another side, and be fixedly connected with by the mode of spraying and adhesive bonding agent.
Further, described second elasitic layer is silastic-layer, width is 1-8mm, thickness is identical with the thickness of described metallic shim body, one side of the second elasitic layer is provided with flange, the flange of described second elasitic layer one side merges bonding with the recess of described stretchable layer one side, and the thickness of the polytetrafluoroethylene floor that described rubber sleeve applies on the surface is 50-300 μm.
When fastening piece is not also tightened downwards, the rubber sleeve of metallic shim and fastening piece running fit, metallic shim outward edge and engine flange contact internal walls or leave very little assembling gap, when fastening piece is tightened downwards, fastening piece will compress stretchable layer, flange on stretchable layer and groove will extend to both sides expansion, cause the rubber sleeve in metallic shim can shrink and extrude fastening piece, when the pressure that fastening piece is downward is excessive, namely the elastic potential energy of the second elasitic layer has been exceeded, second elasitic layer can drive rubber sleeve to tilt up or down slightly, till fastening piece is tightened, when this state, metallic shim tightly propped up fastener surface, rubber sleeve is then as sucker, tightly touch fastening piece, sealing place is without any gap, reach good sealing effect, and when flange and fastening piece vibrate or fastening piece receives power in a lateral direction, due to elasticity and the absorbing effect of the first elasitic layer and the second elasitic layer, rubber sleeve still tightly can touch fastening piece, and the second elasitic layer is silicone rubber composition, silicone rubber is coated with teflon coating, this makes when there is relative sliding, the power acted on surface obtains and slows down, surface of contact relative friction coefficient is little, can not cause fastening piece and scrape damage, ensure that the dimensional stability of metallic shim and fastening piece, maintain sealing effect further.Simultaneously, owing to having circle first elasitic layer at metallic shim body and seal washer joint, first elasitic layer can by shock absorption, make metallic shim and flange inner wall relative sliding can not occur or very little relative sliding occurs, slow down scraping wearing and tearing, ensure that the dimensional stability of metallic shim and flange.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
1, mainly solve the problem of sealing difference when two planes connect, make metallic shim in dynamic process, also can maintain good sealing effect.
2, solve the problem that gasket seal, fastening piece and contact surface abrasion are serious, ensure that the dimensional stability of metallic shim, surface of contact and fastening piece.
