Abstract
The utility model discloses a mechanical oil seal, which belongs to a sealing element and comprises a metal pressure bearing ring and a rubber sealing element, wherein the rubber sealing element is arranged in the metal pressure bearing ring, the rubber sealing element comprises a rubber sealing ring and a V-shaped spring elastomer, the V-shaped spring elastomer is arranged in a groove of the V-shaped spring elastomer annularly arranged on the rubber sealing ring, the outer side surface of the metal pressure bearing ring is provided with an O-shaped sealing ring slot, and an O-shaped sealing ring is arranged in the O-shaped sealing ring slot. Compared with the prior art, the mechanical oil seal has wide applicable temperature and pressure scopes and enhances sealing effect, and with the flexible components, the oil seal is not dropped easily in use when the external environmental factor changes, and the leakage of leaked oil of a working chamber is prevented. The utility model has the characteristics of high sealing reliability, reasonable design, simple structure, convenient use and the like, thereby having good application and popularization value.
Description
Technical field
The utility model relates to a kind of Sealing, especially a kind of mechanical oil sealing.
Background technique
Oil sealing is mainly used in sealing low pressure working medium or lubricant oil and leaks and prevent extraneous dust, impurity invasion device interior, at all kinds of oil hydraulic pumps, be extensive use of oil sealing on the running shaft of oil hydraulic motor, leak outside with the leakage oil that stops active chamber, the standard seal part that is used for running shaft now, what adopt usually is packing_seal, rubber seal, labyrinth seal, but labyrinth seal belongs to clearance seal, seal unreliable though packing_seal is economical and allow to exist and leak, and rubber seal Applicable temperature and pressure range limitation, the easy generation came off when externally environment factor changed, and sealing effect is undesirable.At present, good solution is not also arranged.
The model utility content
Technical assignment of the present utility model is to provide a kind of mechanical oil sealing at above-mentioned deficiency of the prior art, this machinery oil sealing has Applicable temperature and pressure range is wide, the unique design of inboard V-arrangement spring body and the outside 3 road O-ring seals, strengthened sealing effect significantly, the sealing difficult drop-off makes more stable, the reliable characteristics more of sealing.
The technological scheme that its technical problem that solves the utility model adopts is: it comprises metal bearing ring and rubber-plastic sealing spare, described rubber-plastic sealing spare is arranged in the metal bearing ring, described rubber-plastic sealing spare comprises rubber seal and V-arrangement spring body, described V-arrangement spring body is arranged in the V-arrangement spring body groove that annular is provided with on the rubber seal, the outer side surface of described metal bearing ring is provided with the O-ring seals groove, is provided with O-ring seals in the described O-ring seals groove.
O-ring seals on the described metal bearing ring outer side surface is 3 roads.
Described V-arrangement spring body is the V-shaped successive turn shaped steel sheet of its section.
Mechanical oil sealing of the present utility model is compared with prior art, have following outstanding beneficial effect: Applicable temperature and pressure range are wide, strengthen sealing effect, adopt elastic component, when externally environment factor changes, difficult drop-off during use, stop the leakage oil of active chamber to leak outside, the sealing reliability height, reasonable in design, simple in structure, characteristics such as easy to use.
Description of drawings
Accompanying drawing 1 is the structural representation of mechanical oil sealing;
Description of reference numerals: 1, O-ring seals, 2, the O-ring seals groove, 3, V-arrangement spring body groove, 4, V-arrangement spring body, 5, the metal bearing ring, 6, rubber seal.
Embodiment
With reference to explaining below 1 pair of mechanical oil sealing work of the present utility model of Figure of description.
Mechanical oil sealing of the present utility model, its structure comprises metal bearing ring 5 and rubber-plastic sealing spare, described rubber-plastic sealing spare is arranged in the metal bearing ring 5, described rubber-plastic sealing spare comprises rubber seal 6 and V-arrangement spring body 4, described V-arrangement spring body 4 is arranged in the V-arrangement spring body groove 3 that annular is provided with on the rubber seal 6, the outer side surface of described metal bearing ring 5 is provided with O-ring seals groove 2, is provided with O-ring seals 1 in the described O-ring seals groove 2.
O-ring seals 1 on described metal bearing ring 5 outer side surfaces is 3 roads.
Described V-arrangement spring body 4 is the V-shaped successive turn shaped steel sheet of its section.
During use, under the elastic reaction of the V-arrangement two-end-point of V-arrangement spring body 4, rubber seal 6 radially the upper end and the internal diameter of metal bearing ring 5 closely cooperate, local and the sealed rotatingshaft in rubber seal 6 lower end radially closely cooperates and slide relative, to realize effective sealing, 3 road O-ring seals 1 on metal bearing ring 5 outer side surfaces also seal effectively to the link in metal bearing ring 5 outsides.
Except that the described technical characteristics of specification, be the known technology of those skilled in the art.
