Abstract
The invention discloses a shaft seal device. The shaft seal device comprises a main shaft, a bearing box, a bearing, an end cover, a fixed ring, a moving ring, a gasket, a filler sealing piece and a seal pressing plate, wherein the bearing box is sleeved on the main shaft; the bearing is positioned in the bearing box and fixed on the main shaft; the end cover is sleeved on the main shaft, arranged at an opened side of the bearing box, and matched and fixed with the bearing box; a shoulder hole is arranged on the one side of the end cover, close to the bearing, and a counterbore is arranged on the other side of the end cover; the fixed ring, the gasket and the moving ring are fixed in the shoulder hole from inside to outside in sequence; the moving ring and the shoulder hole are in interference fit; the moving ring is tightly attached on the fixed ring by the gasket; the filler sealing piece is fixed in the counterbore; and the seal pressing plate is tightly pressed the filler sealing piece and is fixed on the end cover. According to the scheme of the invention, the shaft seal device prolongs the length of the shaft sealing surface, improves the sealing effect, prevents the oil leakage phenomenon, has a simple structure, and is long in service life and convenient to maintain.
Description
Technical field
The present invention relates to a kind of seal arrangement, especially a kind of shaft sealer of motor belongs to the gland seal device technical field.
Background technique
Axle envelope is the seal arrangement of leak of liquid between the axle and the bearing that prevent motor, the housing.The shaft seal structure that generally uses at present is that Sealing of interpolation between the end cap of axle and bearing housing, sealing part all are the rubber skeleton sealings.Because the sealing part is rubber product, motor in the running, the sealing part is very serious with the wearing and tearing of axle, and the Sealing easy ageing needs often to change, its working life is shorter, repairs very inconvenient.In addition, only adopt the rubber skeleton sealing, its sealing effect is very undesirable, not very big change of oil leakage phenomenon, and motor burns out because of serious leakage of oil often, has reduced the life-span of motor, has increased the maintenance cost of machinery equipment.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of good sealing effect, long service life.Gland seal device easy to maintenance.
Technical solution of the present invention is achieved in that a kind of gland seal device, comprises main shaft, bearing housing, bearing, end cap, stationary ring, rotating ring, packing ring, packing seal element and sealing clamp; Said bearing housing is enclosed within on the main shaft; Said bearing is positioned at bearing housing, and bearing fixing is on main shaft; Said end cap is enclosed within on the main shaft, is located at the opening side of bearing housing, and it is fixing to match with bearing housing; On the said end cap, have shoulder hole near a side of bearing, opposite side has counterbore; In the said shoulder hole, be fixed with stationary ring, packing ring and rotating ring from inside to outside successively; Said stationary ring and shoulder hole are interference fit; Said rotating ring is close on the stationary ring through packing ring; Said packing seal element is fixed in the counterbore; Said sealing clamp presses packing seal element, and sealing clamp is fixed on the end cap.
Preferably, the thickness of said stationary ring is 1.5 times of rotating ring thickness.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Gland seal device of the present invention; The sealing configuration that adopts rotating ring, stationary ring to combine is fixed between axle and the end cap, and fits with bearing; Opposite side at end cap adopts sealing clamp packing seal element to be pressed between axle and the end cap; Prolong the length of shaft sealing face, improved sealing effect, prevented the generation of oil leakage phenomenon; Adopt the present invention program's gland seal device, it is simple in structure, long service life, and easy to maintenance.
Description of drawings
Below in conjunction with accompanying drawing technological scheme of the present invention is described further:
Accompanying drawing l is the structural representation of gland seal device of the present invention;
Accompanying drawing 2 is the sectional view of end cap in the gland seal device of the present invention;
