Abstract
The utility model provides a dustproof and waterproof roller sealing structure which comprises a movable float sealing seat, a static float sealing seat, a floating oil seal, a movable float sealing ring, a static float sealing ring, a locking nut, an O-shaped sealing ring and a felt ring. The floating oil seal, a labyrinth seal, the O-shaped sealing ring and the felt ring are combined for seal. By means of the dustproof and waterproof roller sealing structure, the problems that a sealing part is abraded due to the fact that the sealing part of an existing roller is invaded by slime water and the like, so that the sealing part easily loses efficacy and sealing is difficult are solved, the service life of the roller is prolonged, the rejection rate of parts is lowered, and the problem that sealing of the roller easily fails, and the roller is difficult to seal are effectively solved.
Description
Technical field
The utility model relates to a kind of dustproof and waterproof cylinder sealing configuration, particularly relates to the cylinder dustproof and waterproof sealing configuration using under a kind of coal mine.
Background technique
Cylinder is vitals and the constituent element in belt conveyor systems, belt conveyer for coal mine cylinder indispensable part especially aspect Coal Transportation.In Coal Transportation process, the cylinder in band conveyer lower end, is often immersed in the mixtures such as water coal slime for a long time, and environment is extremely severe, therefore requires cylinder to have good sealability to water, coal slime, dust etc.And current its sealing configuration of existing cylinder is all comparatively simple, generally only use O type circle or felt collar to seal, in use for some time, O type circle or felt collar will lose efficacy with serious wear because of aging, thereby cause cylinder seal failure, cause cylinder support bearing unstable wear and cause cylinder normally to work.
Summary of the invention
The purpose of this utility model is to provide a kind of dustproof and waterproof cylinder sealing configuration, by adopting multiple seal form to carry out combination seal, has effectively improved cylinder sealing effect and working life, has guaranteed the normal use of delivered downhole mechanism.
The technical solution of the utility model is: a kind of dustproof and waterproof cylinder sealing configuration, comprise cylinder, bearing spider, support, bearing, moving floating sealing base, quiet floating sealing base, back shaft, outside framework oil seal, quiet floating sealing ring and moving floating sealing ring, it is characterized in that moving floating sealing base has the mutually nested formation labyrinth seal of raised step of groove and quiet floating sealing base end face; Moving floating sealing base endoporus has circular groove, and felt collar is installed in circular groove, and felt collar and quiet floating sealing base cylindrical form motive sealing; Moving floating sealing base interior edge face has circular groove, O type circle I is installed in circular groove and forms static seal; Quiet floating sealing base endoporus has circular groove, and circular groove is provided with O type circle II, and forms static seal with back shaft interference fit; Quiet floating sealing ring and moving floating sealing ring complement each other to form float grease seal; Outside framework oil seal is arranged in bearing spider cavity, and between back shaft, forms rotary seal.
Wherein moving floating sealing base, bearing spider and support are bolted, and rotate with cylinder.
Wherein quiet floating sealing base is locked and is located by locking nut.
The utility model has adopted the combination seal of float grease seal and multiple seal form, efficiently solve the easily problem of inefficacy, difficult sealing of cylinder sealing, reduce the scrappage of component, improved the working life of cylinder, guaranteed the normal use of delivered downhole mechanism.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1 and Figure 2, moving floating sealing base (7) endoporus has circular groove, and circular groove is provided with felt collar (13), and felt collar (13) forms motive sealing with quiet floating sealing base (8) cylindrical, plays the effect of primary seal.
Moving floating sealing base (7) has groove, and the mutually nested formation labyrinth seal of boss with quiet floating sealing base (8) end face, plays the effect of secondary seal.
Quiet floating sealing ring (14) complements each other to form float grease seal with moving floating sealing ring (15), plays primary seal effect.
Quiet floating sealing base (8) endoporus has circular groove, and circular groove is provided with O type circle II (12), and with back shaft (10) interference fit, play static seal effect.
Quiet floating sealing base (8) is locked and is located by locking nut (9), guarantee the positioning relation of quiet floating sealing base (8) and moving floating sealing base (7), make moving floating sealing ring (15) there is the reliable sealing that contacts with quiet floating sealing ring (14).
Moving floating sealing base (7) interior edge face has circular groove, and O type circle I (12) is installed in circular groove, guarantees that the things such as water coal slime can not immerse in bearing spider (2) by driven floating sealing base (7) interior edge face.
Moving floating sealing base (7) is processed with raised step, and raised step plays positioning bearing (4) effect.
Moving floating sealing base (7), bearing spider (2) are connected by bolt (6) with support (3), guarantee that moving floating sealing base (7) can rotate with cylinder (1).It is upper that bolt (6) is pressed on moving floating sealing base (7) by pad (5), adjusts axial pre tightening force.
Outside framework oil seal (11) is arranged in bearing spider (2) cavity, and forms rotary seal between back shaft (10), prevents the leakage of lubricant medium.
The above embodiment is a kind of preferred version of the utility model, not the utility model is done to any pro forma restriction, also has other variant and remodeling under the prerequisite of technological scheme that does not exceed claim record.
