Abstract
The utility model discloses a rotary dynamic seal device, belongs to a sealing device, and is to provide a sealing device, which has simple structure and excellent sealing effect, and is easy to be maintained and used. The utility model comprises an oil slinger and an end cover. The basin-shaped oil slinger (2) is fixed on an axis of rotation (6); an oil gallery (8) is arranged on the left side; an end cover (3) having an annular groove on an inner circle is enclosed on the axis of rotation, is permanently joined to a case (1); the annular groove is filled with dustproof filler (4). The utility model has simple structure and excellent sealing effect, and can substitute for the present sealing devices of various machine bearings, such as bearing boxes and gear cases and so on.
Description
Technical field: the utility model relates to a kind of seal arrangement, relates in particular to a kind of seal arrangement of oil-lubricated bearing.
Background technique: at present, the associated sealing arrangement for bearings that is used on the machines such as various bearing housings, gear-box mainly contains: stuffing seal, seal ring seal arrangement etc.The former offers annular groove on housing, fill felt in the groove or filler use in other sealing, utilize felt or filler to stop up gap between rotatingshaft and the housing, thereby realization is prevented dust and prevented the purpose that lubricant oil leaks; Its defective is that felt or filler are worn easily, and working life is short.The latter utilizes the resiliently deformable of rubber seal to stop up gap between housing and the rotatingshaft; Its shortcoming is that rotatingshaft weares and teares easily, seal ring is aging easily, and working life is shorter.
Summary of the invention: at the above-mentioned defective that exists in the prior art, the utility model aims to provide a kind of simple in structure, maintenance and rotary dynamic seal device easy to use, good sealing effect.
To achieve these goals, the utility model by the following technical solutions: it comprises disc and end cap; The disc of peviform is fixed on the rotatingshaft, and the left side is provided with end cap sky that oil duct, interior circle be provided with annular groove and is enclosed within on the rotatingshaft and with housing and is fixedly connected, and is filled with dustproof filler in the described annular groove.
Be provided with frustoconic shape air chamber left large and right small on the right side of end cap, end cap is provided with the air flue that communicates with air chamber.
Compared with the prior art, the utility model is provided with the oil duct of an annular in a side of end cap because on the basis of traditional end cover structure, thereby again can be in oil duct flow back into housing after making the fluid that leaks along rotating shaft direction be thrown out of and do not leak outside; In addition, owing to also be provided with an air chamber, utilize pressurized air the dust that accumulates between end cap and the rotatingshaft outwards can be blown out, thereby reach the dust-tight purpose at the opposite side of end cap.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure: housing 1 disc 2 end caps 3 dustproof filler 4 air chambers 5 rotatingshafts 6 air flues 7 oil ducts 8
Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
As shown in Figure 1: the disc 2 that is positioned at housing 1 adopts the mode of interference fit or screw lock to be fixed on the rotatingshaft 6, and the end cap 3 that sky is enclosed within on this is pressed on the housing 1 by screw.The inner circle of end cap 3 has annular groove, and dustproof filler 4 is installed in the groove; The left side of end cap 3 is provided with the boss of a circle, has the oil duct 8 of an annular on the periphery of this boss; The boss of described end cap 3 stretches in the basin mouth of peviform disc 2 and with at the bottom of the basin and maintains a certain distance.In order in the dust pollution serious environmental, to improve dustproof effect, can also be provided with on the right side of end cap 3 left large and right small, be trumpet-shaped frustoconic shape air chamber 5, end cap 3 is provided with the air flue 7 that communicates with air chamber 5; During use, pressurized air is fed air flue 7, can in air chamber 5, form an annular air curtain of outwards blowing, thereby play further dust-tight effect.
Claims (2)
1. a rotary dynamic seal device comprises disc and end cap; It is characterized in that: the disc of peviform (2) is fixed on the rotatingshaft (6), and the left side is provided with end cap (3) sky that oil duct (8), interior circle be provided with annular groove and is enclosed within rotatingshaft (6) and goes up and be fixedly connected with housing (1), is filled with dustproof filler (4) in the described annular groove.
2. rotary dynamic seal device according to claim 1 is characterized in that: be provided with frustoconic shape air chamber (5) left large and right small on the right side of end cap (3), end cap (3) is provided with the air flue (7) that communicates with air chamber (5).
