Abstract
The utility model relates to a shaft radial sealing plate for transmission devices, a transmission shaft (4) is arranged on a frame (1) through the support of a bearing (3), an oil seal end cover (5) is fixed on the frame (1) through a spigot, a oil seal (6) is inlaid in the internal hole of the oil seal end cover, and an oil seal lip is frapped on the transmission shaft through a spring (8), a sealing plate (7) inside the oil seal (6) static/close is fitted with the outside surface of the transmission shaft, the ex-circle sealing surface (9) of the sealing plate slide is fitted with the internal hole of the frame (1). The utility model, applying the moving/static sealing principle, allows the internal hole of the sealing plate stationary close fitted with the shaft diameter, using the oil seal and the sealing plate in pairs to ensure double sealing effect.
Description
Technical field
The utility model relates to a kind of Sealing of mechanical transmission, specifically a kind of diameter of axle sealing plate that is applicable to multiple mechanical transmission sealing occasion.
Background technique
In all kinds of mechanical transmissions, seepage can cause many-sided harm, as causes material waste and environmental pollution, and the leakage of inflammable, explosive, hypertoxic, corrosivity, radioactive material will jeopardize personal safety, cause equipment failure.Intrusion equipment such as the gas in the environment, water and dust can pollute working medium, influence quality of product or aggravation parts depreciation, shorten service life of a machine, and the fluid machinery internal leakage influences volumetric efficiency, even makes machine failure.Oil sealing is one of main Sealing in the mechanical transmission, and the function of oil sealing is to stop to leak, and the quality of oil seal structure, quality is directly determining the sealing and the service behaviour of mechanical transmission.
At present, a kind of skeleton rubber seal, it is a kind of radially contact-type oil sealing.The seal ring that this oil sealing is made by oil resistant rubber, be positioned at the metal frame of seal ring and the lock ring spring that is enclosed within around the sealing lip is formed.During use, oil sealing is pressed in the oil sealing end cap, is enclosed within on the transmission shaft, realize the radial seal of axle, prevent to leak, utilize spring to make the contractile force of seal lip keep constant.This structure only has one lip to seal in use, and the radial seal effect of axle is good inadequately, easily seepage oil.
Summary of the invention
The purpose of this utility model provides a kind of employing static and dynamic sealing principle, the quiet drive fit of the sealing plate endoporus and the diameter of axle, and oil sealing and sealing plate are used in pairs, play the double seal effect, and the transmission seal device of compact structure, long service life.
In order to achieve the above object, the utility model is achieved in that transmission shaft is bearing on the body by bearing, the oil sealing end cap is fixed on the body by seam, oil sealing is embedded on the oil sealing end cap endoporus, oil seal lip tightens up on transmission shaft by spring, the sealing plate of described oil sealing inboard is quiet to tightly fit on the transmission shaft external diameter, and sealing plate cylindrical sealing surface and body endoporus are slidingly matched.
Described sealing plate is flexible member or rigid pipe, and its inner round portion was a hard material when sealing plate was flexible member, and the outer ring part is a flexible material.Sealing plate cylindrical sealing surface shaft section be shaped as cylndrical surface or trapezoidal faces or thread profile face or sine and cosine wavy surface or zigzag fashion face.
Owing to adopted above technological scheme, advantage of the present utility model is: sealing plate is quiet to tightly fit on the transmission shaft, its cylindrical sealing surface and body are for being slidingly matched, purpose is the very little gap of control rigid seal plate and body, or certain interference of flexible sealing plate and body, stop lubricated wet goods medium to external leakage, and by preferred wear-resisting rigid pipe or flexible member as sealing plate, thereby strengthened its sealability, prolonged working life, add original oil sealing and realize the sealing of two roads, further strengthened the sealing effect of mechanical transmission.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among Fig. 1, body 1, back-up ring 2, bearing 3, transmission shaft 4, oil sealing end cap 5, oil sealing 6, sealing plate 7, spring 8, cylindrical sealing surface 9.
Embodiment
As shown in Figure 1, transmission shaft 4 is bearing on the body 1 by bearing 3, oil sealing end cap 5 is fixed on the body 1 by seam, oil sealing 6 is embedded on oil sealing end cap 5 endoporus, oil sealing 6 is fixedly to be pressed on the oil sealing end cap 5, oil seal lip tightens up on transmission shaft 4 by spring 8, and oil seal lip and transmission shaft 4 form and slide movingly.Sealing plate 7 has adopted the static and dynamic sealing principle, its method is that sealing plate 7 forms the interference stationary fit by certain magnitude of interference and transmission shaft 4, quiet tightly fitting on transmission shaft 4 external diameters therewith rotated when transmission shaft rotates, sealing plate cylindrical sealing surface 9 form with body 1 endoporus and slide movingly.Sealing plate 7 is positioned at oil sealing 6 inboards, and leaves appropriate gap between the oil sealing 6, and both use in pairs.Sealing plate the shaft section of cylindrical sealing surface 9 be shaped as cylndrical surface, trapezoidal faces, thread profile face, sine and cosine wavy surface, zigzag fashion face etc., its objective is and reduce and the body friction.During work, sealing plate 7 rotates with transmission shaft 4, and its cylindrical sealing surface 9 slides movingly with body 1 endoporus, stops oil seepage, forms a pair of double-layer seal with original oil sealing 6, has guaranteed the sealability of mechanical transmission mechanism.
Claims (3)
