Abstract

The utility model belongs to the technical field of liquid seals, in particular to a novel oil seal which comprises an annular oil seal main body. At least one annular sealed installation groove is formed on an outer ring face of the oil seal main body, sealing rings are arranged in the sealed installation grooves, and the thickness of each sealing ring is larger than the depth of each sealed installation groove. An annular groove is arranged on one end face of the oil seal main body, the cross section of the groove is in a shape similar to a V, a V-shape spring is installed in the groove, and the groove wall of the groove expands outwards under the action of the V-shaped spring. The novel oil seal is good in sealing performance, simple in structure, safe and reliable and suitable for being installed an axial product with the appropriate size.

Description

A kind of novel oil sealing
Technical field
The utility model belongs to the hydraulic seal technical field, refers in particular to a kind of novel oil sealing.
Background technique
Oil sealing can prevent effectively that liquid medium from spilling, and is characterized in having lower leak-down rate, heat-resisting and withstand voltage wider range from the mechanism of sealing.The external peripheral surface of general oil sealing is smooth cylinder, and its sealing guarantees by the magnitude of interference of rubber, for guaranteeing sealing effect in the less situation of operating oil pressure.But in the situation large to oil pressure, that the oil sealing external diameter is less, oil sealing is extruded under the effect of oil pressure easily; If increase the magnitude of interference of oil sealing outer ring, the assembling Rear oil seal easily produces distortion, the corresponding decline of its sealability.
Summary of the invention
The purpose of this utility model is to provide a kind of oil seal of safe and reliable good sealing effect.
For achieving the above object, the utility model provides following technological scheme: a kind of novel oil sealing, the oil sealing body that comprises ring-type, form the sealing mounting groove of at least one annular on the outer ring surface of oil sealing body, be provided with seal ring in the sealing mounting groove, the thickness of described seal ring is greater than the degree of depth of sealing mounting groove; The oil sealing body wherein be provided with annular groove on the end face, the transverse section of groove is similar to V-arrangement, and the V-arrangement spring is installed in the groove, the cell wall of described groove is lower outside of V-arrangement spring action.
The inner ring surface inwardly protruding of described oil sealing body forms the lip limit, and described lip limit is positioned at a side that is provided with described groove of oil sealing body.
The utility model beneficial effect compared to existing technology is: form the sealing mounting groove of at least one annular on the outer ring surface of oil sealing body of the present utility model, be provided with seal ring in the sealing mounting groove; The oil sealing body wherein be provided with annular groove on the end face, the transverse section of groove is similar to V-arrangement, the V-arrangement spring is installed in the groove, the cell wall of described groove is lower outside of V-arrangement spring action, this design so that the sealability of oil sealing body greatly strengthen, it is simple in structure, and is safe and reliable, is fit to be installed on the axis products of suitable dimension.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, a kind of novel oil sealing comprises the oil sealing body 4 of ring-type, forms the sealing mounting groove of at least one annular on the outer ring surface of oil sealing body, be provided with seal ring 1 in the sealing mounting groove, the thickness of described seal ring 1 is greater than the degree of depth of sealing mounting groove; Oil sealing body 4 wherein be provided with annular groove on the end face, the transverse section of groove is similar to V-arrangement, and V-arrangement spring 2 is installed in the groove, the cell wall of described groove is lower outside of V-arrangement spring 2 effect.
The inner ring surface inwardly protruding of described oil sealing body 4 forms lip limit 4, and described lip limit 4 is positioned at a side that is provided with described groove of oil sealing body 4.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
