Abstract
The utility model discloses a sealing type sliding bearing which comprises a casing, an inner sleeve of the bearing, and a sealing ring, wherein two baffle rings are respectively arranged on both ends of the casing; the inner sleeve of the bearing is tightly sheathed and fixed in a cavity which is composed of the casing and the baffle rings, the inner diameter of the inner sleeve of the bearing is smaller than the inner diameter of each baffle ring, and thus, the inner sleeve of the bearing can be better contacted with a rotating shaft. Two sealing rings are respectively installed on the outer side surfaces of the two baffle rings, and each sealing ring is tightly sheathed on the rotating shaft; a baffle cover is installed on the outer side surface of each sealing ring, each baffle cover is fixed on the casing or/and each baffle ring, and then, each baffle cover, each sealing ring and each baffle ring can be conveniently and mutually contacted and sealed; simultaneously, the casing and each baffle cover can also be installed in a bearing seat, and then, each baffle cover, each sealing ring and each baffle ring are mutually contacted and sealed through two end walls of the bearing seat. The utility model has the advantages of good sealing performance, good abrasion resistance, good vibration resistance, large bearing capacity and long service life, and is suitable for various rotation speeds, various loads and various adverse environment places.
Description
One. technical field: the utility model relates to a kind of plain bearing arrangement, the sealed type plain bearing arrangement that the silt serious condition is worked down in particularly a kind of water that can suit.
Two. background technique: the metal current sliding bearing requires all very high to Environmental Conditions, require oil lubrication good, can not have dust and sand to enter working surface, in case lubricated bad or have sand grains, impurity to enter, very under the situation that quick-wearing, especially load ratio are bigger.Common seal arrangement is easy to damage under some bad working environment, does not have the effect that prevents that for a long time foreign material from entering.The 2nd, the metallic material friction pair is not wear-resisting, the sliding axle load-bearing of doing.Present some nonmetallic material sliding bearings that use, bearing capacity is poor, not good lubricated can not fine work, do not satisfy usage requirement under a lot of operating modes of so-called self-lubricating property.Such as the sliding bearing that nylon is done, friction factor is big, and the wearing and tearing to axle during oil-free lubrication are very serious.Because the work of sliding bearing is the bearing inner circumferential surface to be done relative to rotation with the surface of axle and moves, and for realizing rotation, is necessary for the Spielpassung form between the two, the condition that has existed foreign material to enter like this.For stopping that foreign material enter normal use seal arrangement, traditional filler or seal ring sealing on axle and play the effect of sealing, but the gap just occurs when using the wearing and tearing elasticity of certain hour seal ring itself not compensate by self elastic cuffs, lose the effect of sealing.Other mechanical sealings are realized for utilizing the moving good contact that encircles end face surely, both on axle, fixed a ring, on another relative movement part, fixed a ring, made between two surface of contact that encircle very close to each other, the processing request of this sealing is very high, in the use good oil lubrication will be arranged.Need oil-filling device, using a lot of component like this must be very high maintenance difficulty of cost, and the place that can use seldom.
Three, model utility content:
The purpose of this utility model: overcome above-mentioned deficiency of the prior art, and provide a kind of simple in structure, sealing is reliable, and surface friction drag is little, the sealed type plain bearing arrangement of long service life.
The technical solution of the utility model: a kind of sealed type plain bearing arrangement, contain shell, bearing inner sleeve and seal ring, wherein the shell two ends are respectively equipped with a baffle ring, the tight suit of bearing inner sleeve is fixed in the cavity of shell and baffle ring composition, and the internal diameter of bearing inner sleeve is less than the internal diameter of baffle ring, so that bearing inner sleeve contacts with rotating shaft better, at the outer side surface of two baffle rings a seal ring is installed respectively, the sealing ring closely is sleeved in the rotating shaft, at the outer side surface of seal ring a door is installed respectively, described door is fixed on shell or/and on the baffle ring, so that make door, the sealing of fitting mutually of seal ring and baffle ring, perhaps described shell and door are installed in the bearing support, and the end walls by bearing support makes door, the sealing of fitting mutually of seal ring and baffle ring.
Described bearing inner sleeve and seal ring are made by wear-resisting low friction, shock proof nonmetallic material, and shell is made by metallic material; Phase interfix embedding between baffle ring, seal ring and the door forms labyrinth sealing, and the lubricant grease of annotating in the chamber, labyrinth is convenient to the lubricated and sealing of bearing inner sleeve.
Described baffle ring and shell are integral structure, or are split-type structural, and baffle ring is fixed on the shell by fastening piece.
The beneficial effects of the utility model:
1. the utility model adopts low coefficient of friction, wear-resistant, shock proof high-performance nonmetallic material to make bearing inner sleeve and seal ring, its wear resistance and good anti-vibration, and bearing capacity is big, and shell and baffle ring are clipped in the middle bearing inner sleeve, improves the bearing capacity of bearing inner sleeve more.
2. seal ring of the present utility model is close on door, the baffle ring works, and its internal diameter closely is enclosed within the rotating shaft, and frictional force is little, can not produce big frictional force such as rubber seal etc., wearing and tearing are few, and phase interfix embedding between baffle ring, seal ring and the door in addition forms labyrinth sealing, the lubricant grease of in the chamber, labyrinth, annotating, therefore, its good seal performance, long service life, reduce maintenance frequency and cost, improve economic benefit of enterprises.
3. the utility model is simple in structure, makes easily, and each constituent elements easy accessibility is easy to install and maintenance, reduces labor intensity of operating personnel.
4. the utility model applied range is applicable to the place of various rotating speeds, various load, various rugged environment to have good social benefit and economic benefit after the popularization.
