For non-contacting labyrinth seal, but this kind of sealing means can not effectively prevent water and dust entered from axle external part etc. from having
Evil impurity, therefore this kind of sealing structure can not meet the degree of protection of high sealing requirement.
The content of the invention
, being capable of the stricter sealing of countershaft realization the invention provides a kind of sealing structure of rotating shaft.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals：
A kind of shaft sealer in electromechanical equipment, including axle and machine wall, in addition to seal receptacle, top cover, screw rod and pressure ring,
Seal receptacle is fixed on machine wall, and the axle passes through from seal receptacle, pressure ring and top cover, and sealing is provided between top cover and seal receptacle
Ring, pressure ring push down the sealing ring, and pressure ring is provided with pressure ring nut, and screw rod is connected to sealing through top cover, pressure ring nut thread
On seat, falope ring is also embedded with the top cover, the falope ring is located on the inside of pressure ring.
Preferably, the section of falope ring shape triangular in shape, the falope ring are close to one end of inside of top cover
The bottom of its triangular-section.When Axial and radial is beated, axle bends, and falope ring is resisted against on pressure ring and deforms upon pressure
Contracting, top cover are able to rotate to pressure ring side.
Preferably, sealing ring is higher by top cover, pressure ring is pressed on sealing ring, and pressure ring does not contact with top cover.Sealing ring is higher by
Top cover rotates slot milling also for top cover.
Preferably, screw rod one end is provided with top nut, in addition to spring, screw rod pass through spring, and both ends of the spring pushes up respectively
Firmly top nut, top cover.Position by adjusting top nut can adjust pressure of the top cover to sealing ring.
Preferably, seal receptacle is provided with the sealed wall being bonded with machine wall, the sealed wall of seal receptacle is provided with sealing ring.
Preferably, being additionally provided with dust retaining ring on axle, the dust retaining ring, seal receptacle are described respectively positioned at machine wall away from both sides
Dust retaining ring includes main body, the first sealing lip and the second sealing lip, and first sealing lip, the second sealing lip are located at main body both ends,
First sealing lip and the second sealing lip tilt towards seal receptacle side.
The present invention realizes the strict sealing of countershaft as a result of above technical scheme, prevent dust and liquid from
The edge of rotating shaft is penetrated into.
