Abstract
The utility model belongs to the field of plastic mechanical fittings and particularly relates to a plastic mechanical oil seal. The plastic mechanical oil seal comprises a copper sleeve, wherein a plurality annular T-shaped grooves are arranged in the peripheral surface of the sleeve, a T-shaped sealing ring is embedded into each T-shaped groove, an installing step is arranged in the sleeve, an inner sealing ring is fixedly arranged on the installing step, an annular rectangular slot is arranged in the end surface of the inner sealing ring, a plurality of elastic parts are fixedly and radially arranged in the rectangular slot, and the notch of the rectangular slot is sealed through a sealing pad. The plastic mechanical oil seal has the advantages that the plastic mechanical oil seal has a simple and practical structure and can achieve a reliable internal and external sealing effect through the convex ridges of the T-shaped sealing rings and the inner sealing ring.
Description
Technical field
The utility model belongs to plastics machinery accessory field, specifically a kind of plastics machinery oil sealing.
Background technique
Oil sealing is mainly used in sealing low pressure working medium or lubricant oil leaks and prevents extraneous dust, impurity invasion device interior, at all kinds of oil hydraulic pumps, on the running shaft of oil hydraulic motor, be widely used oil sealing, to stop the leakage oil in active chamber to leak, the present standard seal part for running shaft, what conventionally adopt is packing_seal, rubber seal, labyrinth seal, although it is unreliable to seal but packing_seal is economical, often there will be the situation of leakage, and rubber seal Applicable temperature and pressure range limitation, in the time that changing, easily produces external environmental factor the situation that then ageing of rubber comes off, sealing effect is poor, labyrinth seal belongs to clearance seal, manufacture difficulty of processing is large, therefore in plastics machinery field, also there is no good oil seal structure.
Summary of the invention
The utility model, for the deficiency existing in above-mentioned technology, proposes the plastics machinery oil sealing of a kind of good sealing effect, long service life.
The utility model provides following technological scheme:
Plastics machinery oil sealing, it comprises copper sleeve, this sleeve side face is provided with the T-shaped groove of some annulars, T-shaped groove is embedded in T-shaped seal ring, in sleeve, be provided with an installation step, be fixed with inner seal ring on installation step, the end face of inner seal ring is provided with annular rectangle groove, in rectangle groove, be radially fixed with some elastic members, the notch of rectangle groove seals by sealing gasket.
Described T-shaped seal ring protrudes from sleeve outer surface.
The inwall of described inner seal ring is provided with corrugated convex ridge.
The utility model has the advantages that simple and practical, seal action reliably inside and outside playing by the convex ridge of T-shaped seal ring and inner seal ring.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, it comprises copper sleeve 1, this sleeve 1 side face is provided with the T-shaped groove of some annulars, T-shaped groove is embedded in T-shaped seal ring 2, in sleeve 1, be provided with an installation step, be fixed with inner seal ring 3 on installation step, the end face of inner seal ring 3 is provided with annular rectangle groove, in rectangle groove, be radially fixed with some elastic members 4, the notch of rectangle groove seals by sealing gasket 5.
Described T-shaped seal ring 2 protrudes from sleeve 1 outer surface.
The inwall of described inner seal ring 3 is provided with corrugated convex ridge 3a.
