Abstract
The invention discloses a labyrinth sealing mechanism comprising a convex seal ring disposed on a rotating shaft and another convex seal ring disposed on the inner wall of a shaft hole. The two convex seal rings cross with each other to form a labyrinth sealing structure. Space between the convex seal rings is filled with sealant. The convex seal rings never contact with each other, so that frictional resistance is reduced. The stacked seal rings are more effective and more reliable than the single seal ring.
Description
Technical field
The present invention relates to a kind of labyrinth sealing mechanism, belong to Sealing field.
Background technique
Traditional rotating shaft sealing just seals by seal ring and the seal gease of monolithic, and this sealing means is larger to the generation resistance of rotatingshaft, and sealing effect is also bad.
Summary of the invention
The object of the invention is to: provide a kind of good sealing effect, the sealing mechanism that rotational resistance is low.
The present invention realizes in the following way:
A labyrinth sealing mechanism, comprises rotatingshaft, axis hole and Sealing, and described Sealing is arranged between rotatingshaft and axis hole, and described Sealing comprises rotary seal and fixing seals;
Described rotary seal is fixed on axostylus axostyle, described rotary seal comprises pedestal A and some tabs A, described pedestal A is and the coaxial cylindrical body of axostylus axostyle, described some tabs A are ring, press identical interval L array arrangement on pedestal A, the annular inner circle of described tabs A is fixedly connected with pedestal A, and the plane of described some tabs A is vertical with the axis of pedestal A;
Described fixing seals is fixed on shaft hole inner wall, described fixing seals comprises pedestal B and some tabs B, described pedestal B is cylindric, between the outer wall of described pedestal B and shaft hole inner wall, be fixedly connected with, described some tabs B are ring, it is upper that described some tabs B are fixed on pedestal B by identical interval L, and the cylindrical of described some tabs B is fixedly connected with the internal face of pedestal B;
Described some tabs B and some tabs A intercross arrangement, in the interval L of described some tabs B between some tabs A.
As further innovation of the present invention, in described rotary seal, be provided with skeleton, described skeleton comprises support plate and the support plate fixed base of ring, described support plate fixed base is cylindric, it is inner that described support plate fixed base is embedded in pedestal A, and the axle center of described support plate fixed base is coaxial with rotatingshaft, and described support plate is circular, the cylindrical of described support plate is embedded in tabs A, and described support plate is fixedly connected with support plate fixed base.
As further innovation of the present invention, described labyrinth sealing mechanism also comprises fastening piece, described fastening piece is embedded in pedestal A, described fastening piece is cylindric, in described fastening piece, be provided with cylindric through hole, at through-hole wall, be provided with screw thread, described pedestal A is fixed on rotatingshaft by described screw thread.
Beneficial effect: the present invention is by two groups of tabs that cross one another, realize mazy sealed pathway, between the gap of tabs, add seal gease, between tabs, do not contact, reduced surface friction drag, stacked seal ring effect is compared the seal ring better effects if of one chip simultaneously, also more stable.
