Abstract

The utility model relates to an oil deflector ring, and particularly provides an oil deflector ring for the bearing box of a rotary machine. The oil deflector ring comprises an outer oil deflector ring and an inner oil deflector ring which are in embedded connection with each other; and a brush oil deflector ring device is arranged on the inner side of the inner oil deflector ring and the outer oil deflector ring. Compared with the prior art, the utility model has the characteristics of reasonable design, simple structure, low manufacturing cost, good sealing effect and the like.

Description

A kind of bearing in rotating machinery case flinger ring

Technical field

The utility model relates to a kind of flinger ring, and a kind of bearing in rotating machinery case flinger ring specifically is provided.

Background technique

Traditional bearing in rotating machinery case flinger ring device as shown in Figure 1, when machine normally moves, seal by the inside and outside flinger ring of bearing housing and the radial clearance between the rotating shaft, when machine through after a while the operation after, seal clearance increases because of the sound wearing and tearing, reduce the sealing effect of flinger ring, lubricant oil can be outside rotating shaft leaks into bearing housing in the bearing housing; Simultaneously owing to be negative pressure in the bearing housing, outer water vapor and the dust of traditional inevitable bearing housing of bearing housing flinger ring structure is inhaled in the bearing housing, water recovery Cheng Shui, dust fall into oil, cause intaking in the lubricant oil and advancing impurity, have a strong impact on the quality of oil, threaten the safe operation of machine.

Summary of the invention

The utility model is at above deficiency, provide a kind of reasonable in design, simple in structure, fabricating cost is low, the bearing in rotating machinery case flinger ring of good sealing effect, thoroughly solve water inlet in leakage of oil that conventional construction exists and the oil, advance the problem of impurity.

The technological scheme that its technical problem that solves the utility model adopts is:

A kind of bearing in rotating machinery case flinger ring comprises chimeric outer flinger ring and interior flinger ring mutually, and outer flinger ring and interior flinger ring inboard are provided with brush flinger ring device.

Brush flinger ring device comprises brush holder yoke and bristle, and described bristle is fixed in the described brush holder yoke, and described brush holder yoke is fixed in the groove of described outer flinger ring and interior flinger ring inboard.

The normal angle of bristle and described brush holder yoke is θ, and described angle theta value is between 0 °-55 °.

A kind of bearing in rotating machinery case flinger ring of the present utility model is because on traditional bearing case flinger ring; increase one or more brush flinger rings; constitute a brush-broach combination oil catch ring with original flinger ring; can leak by the interior oil of stuffing box bearing case; can stop bearing housing outer water vapor and dust to enter in the bearing housing again; solve the problem of intaking in the oil and advancing impurity, guarantee the safe operation of machine.

Embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.

Provide a most preferred embodiment below:

A kind of bearing in rotating machinery case flinger ring comprises chimeric outer flinger ring 1 and interior flinger ring 2 mutually, and outer flinger ring 1 and interior flinger ring 2 inboards are provided with brush flinger ring device 3.

Brush flinger ring device 3 comprises brush holder yoke 31 and bristle 32, and described bristle 32 is fixed in the described brush holder yoke 31, and described brush holder yoke 31 is fixed in the groove of described outer flinger ring 1 and interior flinger ring 2 inboards.

Bristle 32 is θ with the normal angle of described brush holder yoke 31, and described angle theta value is between 0 °-55 °.

As shown in Figure 2, brush flinger ring sealing device structure of the present utility model is to newly establish brush flinger ring device 3 outside original on flinger ring, the interior flinger ring.Bristle 32 is soft wire or non-metallic fiber, can form flexible contact seal with rotating shaft 4, bristle 32 can be smaller or equal to 0 with the gap of rotating shaft 4, the gap of 0-0.05mm also can be set, thereby reach in the inside salable bearing housing oil stream along rotating shaft 4 to the bearing housing external leakage, outwards can stop water vapor and dust outside the bearing housing to enter in the bearing housing, prevent to intake in the oil, guarantee oil cleaning and effectively sealing.Fig. 3 is that the bristle 32 of brush flinger ring device 3 is put schematic representation, and it is θ that bristle 32 is put the angle, and between 0 °-55 °, bristle 32 can be a fine wire, also can be non-metallic fiber.Fig. 4 is the sectional view of brush flinger ring device 3, and bristle 32 is fixed in the brush holder yoke 31, and brush holder yoke 31 installs and fixes in the circular groove of flinger ring 1, interior flinger ring 2 outside.

Same the utility model also may be used on the oil catch of bearing both sides own, no longer many here narrations.

Above-described embodiment, the utility model embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
