Abstract
The utility model discloses a rubber-plastic composite rotary shaft lip-shaped sealing ring, which comprises an elastic body, a framework, a spring, a main lip of the sealing ring and the like, wherein the framework is arranged in the elastic body, and the spring is positioned at the neck part of the main lip of the sealing ring; a layer of polytetrafluoroethylene PTFE sheet is arranged on the friction contact surface of the main lip of the sealing ring; when the polytetrafluoroethylene PTFE sealing ring is used, the polytetrafluoroethylene PTFE is arranged on a rotating shaft, and the polytetrafluoroethylene PTFE has excellent self-lubricating performance and excellent physicochemical properties such as oil resistance, wear resistance, temperature resistance, aging resistance, strong acid resistance, strong alkali resistance and the like, so that the polytetrafluoroethylene PTFE sealing ring can have good sealing performance and long service life.
Description
One, technical field
The utility model relates to a kind of lip-type packing that is used for the dynamic power machine running shaft, belongs to dynamic power machine rotary seal technical field.
Two, background technique
Traditional lip-type packing that is used for the dynamic power machine running shaft has various ways, as felt ring seal, labyrinth seal, the sealing of RUBBER O shape, rubber lip seal etc., though that these seal rings have is simple in structure, make advantages such as easy, but sealing effect is not good, be easy to wearing and tearing, and working life is shorter, so can not adapt to the needs of high speed engine running shaft journal packing.
Three, summary of the invention
The utility model is intended to overcome above-mentioned shortcoming, and a kind of good seal performance, wear-resisting is provided, and the rubber and plastic composite rotating axle lip-type packing of the employing composite rubber-plastic material of long service life making.
Rubber and plastic composite rotating axle described in the utility model lip-type packing, with nitrile butadiene rubber NBR, acrylate rubber ACM, fluorine rubber FPM elastomer as rotary shaft lip seal, with the polytetrafluoroethylene PTFE material is the high-abrasive material of rotary shaft lip seal master lip, by grafting, crosslinked, with its compound be one, like this, excellent physical and chemical performance such as the good self-lubricating property that can give full play to the polytetrafluoroethylene PTFE material and had and oil resistant, wear-resisting, heatproof, ageing-resistant, anti-strong acid, anti-highly basic.
Through the utility model after the above-mentioned design, the physical and chemical performance that had both had polytetrafluoroethylene PTFE material excellence, had both the outstanding elastic index of rubber material again, the dynamic sealing technology field of the running shaft position harshness in the fields such as high speed engine, aeroengine, diesel engine, motorcycle engine and various machinery, chemical industry, light industry, military project can be widely used in, the technical barrier in high temperature, the dynamic seal (packing) of high speed rotating position can be stablized, solve reliably.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model
Wherein: 1-elastomer 2-skeleton 3-spring 4-seal ring master lip 5-polytetrafluoroethylene PTFE thin slice
Five, embodiment
The lip-type packing of a kind of rubber and plastic composite rotating axle includes parts such as elastomer 1, skeleton 2, spring 3, seal ring master lip 4 and constitutes, and skeleton 2 is inserted in the elastomer 1, and spring 3 is positioned at the neck of seal ring master lip 4; At the friction contact surface of seal ring master lip 4, be provided with one deck polytetrafluoroethylene PTFE thin slice 5, the thickness of polytetrafluoroethylene PTFE thin slice 5 is advisable with 0.05mm-1.5mm.Elastomer 1 adopts nitrile butadiene rubber NBR or acrylate rubber ACM or fluorine rubber FPM to make, elastomer 1 and polytetrafluoroethylene PTFE thin slice 5, by grafting, crosslinked method, with its compound be one.During use, it is installed on the running shaft, because excellent physical and chemical performances such as good self-lubricating property that polytetrafluoroethylene PTFE had and oil resistant, wear-resisting, heatproof, ageing-resistant, anti-strong acid, anti-highly basic just can guarantee that it has excellent sealing performance and working life.
