Abstract
The utility model discloses a gasket of an oil return pipe of a supercharger, which comprises a mounting hole matched with the oil return pipe and is characterized by comprising a base plate formed by a steel plate and a fluororubber layer wrapped on the base plate. An annular convex rib homocentric with the mounting hole is arranged on the periphery of the mounting hole. The gasket of the oil return pipe of the supercharger has certain rigidity and rebounding rate, can enable the supercharge, the oil return pipe gasket and the oil return pipe to be attached tightly, can still be tightly attached to the supercharger and the oil return pipe in vibrating environment, prevents machine oil from leaking, and meets the requirement for sealing of the supercharger oil return.
Description
Technical field
The utility model relates to the engine fittings technical field, relates to a kind of pad that is used for the engine supercharger return tube in particular.
Background technique
Pressurized machine return tube pad is the accessory that seals that is provided with between pressurized machine oil return flange and pressurized machine return tube flange in order to prevent between pressurized machine and the return tube seepage phenomenon to take place.Existing pressurized machine return tube pad adopts the Tinned Steel Sheet edge structure, and the major defect of this structure is can't return after low, the zinc-plated bound edge extrusion-deformation of rebound degree, occurs the oil impregnate phenomenon easily after long-time the use, can't play seal action.Along with increasing day by day of requiring leaked to three in market, existing return tube pad can't satisfy the seal request of increasingly stringent.
The model utility content
The utility model provides a kind of pressurized machine return tube pad, have certain rigidity and rebound degree, pressurized machine, return tube pad and return tube are fitted closely, in vibration environment, still can fit tightly pressurized machine and return tube, make the machine oil can't seepage, satisfy the seal request of pressurized machine oil return.
The utility model is to adopt following technological scheme to realize above-mentioned purpose: a kind of pressurized machine return tube pad, include the pilot hole that cooperates with return tube, it is characterized in that, this pad comprises the substrate that is made of steel plate and is coated on fluororubber layer on this substrate, is provided with the annular convex rib concentric with it in this pilot hole periphery.
As further specifying of such scheme:
Preferably, the thickness of described substrate is 0.3mm～0.4mm.
Preferably, the thickness of described fluororubber layer is 0.01mm～0.03mm.
Preferably, the height of described convex tendon is 0.2mm～0.4mm.
The beneficial effect that the utility model adopts above technological scheme to reach is:
1. pad described in the utility model is provided with convex tendon, has certain rigidity and rebound degree, and pressurized machine, return tube pad and return tube are fitted closely, has therefore strengthened the sealability of this pad.
2. pad described in the utility model also covers one deck fluororubber layer at the steel plate outer surface, make pad have good heat-resisting quantity, oil resistance, chemical resistance, flame resistance, vacuum enhancing, the gap compensation ability and the rebound degree of pad have further been promoted, in vibration environment, still can fit tightly pressurized machine and return tube, make the machine oil can't seepage, satisfy the seal request of pressurized machine oil return.
Description of drawings
Fig. 1 is the structural representation of pad described in the utility model;
Fig. 2 is the partial schematic sectional view of pad described in the utility model.
Description of reference numerals:
The 1-gasket body, 2-pilot hole, 3-convex tendon, 4-mounting hole, 5-substrate, 6-fluororubber layer.
Embodiment
For further setting forth 26S Proteasome Structure and Function of the present utility model, below in conjunction with accompanying drawing and preferred embodiment the utility model is elaborated, but be to be understood that protection domain of the present utility model is not subjected to the restriction of embodiment.
Fig. 1 is the structural representation of pad described in the utility model, as shown in FIG., this gasket body 1 is a platy structure that roughly assumes diamond in shape, this gasket body 1 middle part is provided with a pilot hole that cooperates with return tube 2, in pilot hole 2 peripheral impact briquettings the ring-type convex tendon 3 concentric with pilot hole 2 arranged, be respectively equipped with a mounting hole 4 that is used to install pad in the both sides of this gasket body 1, this gasket body 1 is made of substrate 5 and the fluororubber layer 6 that is coated on these substrate 5 two sides, this substrate 5 adopts SPCC steel plate (the Japanese trade mark, be equivalent to homemade Q195), thickness is 0.35mm, fluororubber layer 6 thickness of steel plate both sides are 0.01mm～0.03mm, and the height of convex tendon 3 is 0.3mm.
Pad described in the utility model adopts steel plate towards convex tendon 3 structures, have certain rigidity and rebound degree, pressurized machine, return tube pad and return tube are fitted closely, and cover one deck fluorine rubber (it is good that fluorine rubber has good heat-resisting quantity, oil resistance, chemical resistance, flame resistance, vacuum enhancing, compressive strain) at surface of steel plate, the gap compensation ability and the rebound degree of pad have further been promoted, in vibration environment, still can fit tightly pressurized machine and return tube, make the machine oil can't seepage, satisfy the seal request of pressurized machine oil return.Simultaneously, fluorine rubber ability-30 ℃～250 ℃ of temperature can satisfy the requirement of pressurized machine returning-oil temperature, and the fluorine rubber oil resistance is good, satisfies the oil resistance requirement of pressurized machine oil return.
Only one of the utility model preferred embodiment shown in the utility model the foregoing description and the accompanying drawing; can not limit to the utility model with this; under the condition that does not break away from the utility model marrow, any change that those skilled in the art did all belongs to protection domain of the present utility model.
