CN206111865U - Novel paste and mould sealed face turntable bearing - Google Patents

Abstract

The utility model provides a novel paste and mould sealed face turntable bearing, the long -life and whole sealed high reliability of realizing the sealing washer. The utility model discloses an it improves to seal up the position to circle inside and outside the bearing, like fig. 2, in original sealing washer (2) sealing edge's friction position, adopt the mode of moulding of pasting to inlay wear ring (5) (seeing fig. 2, fig. 3), sealing washer (2) is direct sealed with wear ring (5) surface contact, in sealing washer (4) sealing edge's friction position, inlay wear ring (6) (seeing fig. 2, fig. 4), sealing washer (4) is direct sealed with wear ring (6) surface contact. The beneficial effects of the utility model are that: adopt novel subsides to mould seal structure, under the motionless condition of the matched part who guarantees original bearing, add and inlay the wear ring, can reduce the rubber seal wearing and tearing and improve the bearing seal effect, be favorable to guaranteeing the bearing quality, guarantee the life of bearing.

Description

New laminating sealing surface turntable bearing

Technical field

This utility model is related to turntable bearing, more particularly to a kind of new laminating sealing surface turntable bearing, i.e. sealing life Longer turntable bearing.

Background technology

Structure substantially sealed off such as Fig. 1 of existing super-huge turntable bearing, the outer ring of bearing (1) embedding sealing circle (2) with it is close (4) seal, to the friction face seal on end face and diametric(al) dustproof effect is played.Because naked outside bearing is most use, and contacts Dust atmosphere, meanwhile, because being very easy to cause sealing ring under axial direction, the comprehensive function of end-play during bearing working Fast Wearing and impurity enter bearing, affect bearing using effect and cause bearing premature breakdown, cause whole set equipment to be safeguarded into This increase, has a strong impact on host work efficiency.Particularly with wind electricity change paddle, yaw, sealing ring and its not is safeguarded and changed It is convenient, change the difficult problem that sealing ring becomes in host maintenance.

The content of the invention

This utility model provides a kind of new laminating sealing structure turntable bearing, realizes that the long-life of sealing ring and entirety are close The high reliability of envelope.

The technical solution of the utility model is as follows：Bearing Internal and external cycle sealing station is improved, such as Fig. 2, original (5) the frictional position of sealing ring (2) seal lip, wear ring is inlayed using laminating mode（See Fig. 2, Fig. 3）, sealing ring (2) directly with Wear ring (5) surface contact sealing；In the frictional position of sealing ring (4) seal lip, wear ring is inlayed (6)（See Fig. 2, Fig. 4）, it is close (4) directly (6) surface contacts sealing with wear ring for seal.

The beneficial effects of the utility model are：Using new laminating sealing structure, in the matching component for ensureing original bearing It is additional to inlay wear ring under conditions of motionless, rubber seal can be reduced and worn and torn and improved bearing seal effect, be conducive to protecting Card bearing quality, it is ensured that the service life of bearing.

Icon explanation：Outer ring 1, sealing ring 2, inner ring 3, sealing ring 4, wear ring 5, wear ring 6.

Specific embodiment

This utility model is described in detail with reference to accompanying drawing.

In the course of processing of outer ring 1, according to the space structure feature of bearing, by the sealing ring 2 of outer ring 1, sealing ring 4 with it is interior The position that circle 3 mutually rubs processes the embedding groove of wear ring, and wear ring 5, wear ring 6 are inlayed respectively wherein, inlays using special Laminating bonding mode.

Under the conditions of New structure seal, the sealing ring of bearing directly contacts sealing with wear-resisting ring surface, and the wear ring is adopted Polytetrafluoro composite is manufactured, and wear ring has that surface smoothness is good, wearability is good, intensity is high, and with the spy of certain elasticity Point；The wear ring is embedded in sealing ring frictional position, can significantly reduce the abrasion of rubber seal, and SimMan universal patient simulator can be by More than 0.2 originally is reduced to 0.1 once, it is contemplated that sealing ring service life can improve 2 times, applies in wind power bearing field, Sealing ring need not be changed in wind power bearing in life cycle within 20 years.For other require the higher bearing of sealing reliability, The important function of the service life for extending bearing will be played.

Claims (2)

1. a kind of new laminating sealing surface turntable bearing, the outer ring of bearing (1) embedding sealing circle (2) with sealing ring (4), its feature exists In the frictional position of, the sealing ring (2) seal lip, (5) wear ring is inlayed using laminating mode；Sealing ring sealing (4) (6) the frictional position of lip, inlay wear ring.

2. new laminating sealing surface turntable bearing according to claim 1, it is characterised in that the sealing ring (2) directly with it is resistance to Bull ring (5) surface contact sealing；(4) directly (6) surface contacts sealing to the sealing ring with wear ring.
