Abstract

The invention relates to a supporting and positioning sealing oil baffle which is composed of an inner ring, an outer ring, an elastic spring and an oil collecting net, wherein a blind hole which is parallel to a rotary shaft is formed on a circumference body wall of the inner ring, wherein the circumference body wall is sleeved on the rotary shaft; the blind hole is internally and axially provided with a limit adjusting nut, a friction arc piece and an elastic spring sequentially; the outer ring is parallel to the rotary shaft and is arranged at the outer side of the inner ring; an inner cavity of the outer ring is buckled and covered on the outer side of the circumference body of the inner ring; the top of a friction arc piece of the inner ring props against the inner wall of the inner cavity of the outer ring tightly in a combined mode; an outer cavity of the outer ring is internally provided with the oil collecting net which is parallel to the rotary shaft; and the corresponding part of the circumference body walls of the inner ring and the outer ring is provided with a radial stop pin or stop key. The supporting and positioning sealing oil baffle provided by the invention has the characteristics of simple structure, safety and reliability, convenience in component replacement, good sealing effect, long service life and the like.

Description

Support the location sealed oil catch

Affiliated technical field the present invention relates to a kind of axial sealer, especially a kind of support location sealed oil catch that is applicable to rotating shaft axial seal.

Background technique is present, and rigidity component composite structure is installed in the many employings of rotation axis seal vertically.In use there is work running, rubs between sealing component and rotating shaft, make component wearing and tearing occur, cause the gap enlargement between Sealing and the rotating shaft, occur leaking seal failure along with rotating shaft.

Summary of the invention the purpose of this invention is to provide a kind of can avoiding and weares and teares, the support location sealed oil catch of good sealing effect.

For achieving the above object; Support provided by the invention location sealed oil catch is made up of interior ring, outer shroud, elastic spring, oil-collecting net; It is characterized in that: be socketed on the blind hole that offers on the interior ring circumference body wall of rotating shaft with shaft parallel, spacing adjustment nut, friction arc spare, elastic spring are installed in the blind hole vertically successively; Be parallel to rotating shaft and be arranged in the outer shroud in the ring outside, the circumferential body outside of ring in its inner chamber button covers on, the tight closing of inwall of the friction arc spare top of interior ring and outer shroud inner chamber is provided with the oil-collecting net of parallel shaft in the outer shroud exocoel.

After adopting said structure, the spacing adjustment nut in regulating in advance in the use in the ring blind hole acts on thrust spring to be positioned at the friction arc spare at its back, and friction arc spare remakes and is used for cavity wall in the outer shroud.The ring disengaging contacts with the rotating shaft outer surface in making, and is suspended in the space of rotating shaft outer surface.Thereby avoid the generation of wear phenomenon, improve the working life of Sealing.

As a further improvement on the present invention, be provided with radial stop pin and locking key in the inner and outer rings circumferential wall.This structure can prevent that inner and outer rings from relatively rotating.

Characteristics of the present invention are: simple in structure, convenient and practical, and long service life.Can avoid the wearing and tearing between axial seal parts and rotating shaft.

Description of drawings Fig. 1 supports the overall appearance structural representation of location sealed oil catch for the present invention.

Fig. 2 is for to show the cross-sectional view along A-A like Fig. 1.

Fig. 3 is for to show along the structural representation of B-B section like Fig. 1.

Fig. 4 supports the mounting structure schematic representation of location sealed oil catch for the present invention.

Embodiment is done further explain below in conjunction with accompanying drawing to the present invention:

Like Fig. 1,2, shown in 4; The present invention supports the location sealed oil catch and is made up of parts such as interior ring 1, outer shroud 2, elastic spring 3, oil-collecting nets 4; Be socketed on 8 symmetrical blind holes that are processed with on the interior ring circumference body wall of rotating shaft with shaft parallel, spacing adjustment nut 5, friction arc spare 6, elastic spring 3 are installed in the blind hole vertically successively; Be parallel to rotating shaft and be arranged in the outer shroud 2 in the ring outside, the circumferential body outside of ring in its inner chamber 9 buttons cover on, the tight closing of inwall of the friction arc spare top of interior ring and outer shroud inner chamber is equipped with the oil-collecting net of parallel shaft in the outer shroud exocoel 11.Inner and outer rings circumference body wall corresponding position is provided with stop pin or locking key 8 radially, and this structure can prevent that inner and outer rings from relatively rotating (showing like Fig. 3).Spacing adjustment nut in regulating in advance in the use in the ring blind hole acts on thrust spring to be positioned at the friction arc spare at its back, and friction arc spare remakes and is used for cavity wall in the outer shroud.The ring disengaging contacts with the rotating shaft outer surface in making, and is suspended in the space of rotating shaft outer surface.Thereby avoid the generation of wear phenomenon, improve the working life of Sealing.And then effectively prevent to be positioned at outer shroud internal retaining surface 10 inboard sealing mediums and reveal and overflow.

Characteristics of the present invention are: simple in structure, good sealing effect, long service life, applied widely, can realize the excellent sealing of the dynamic and static state of running shaft.

Claims
