Abstract
The utility model discloses a wear-resisting bearing bush for a zinc pot roller system. The wear-resisting bearing bush is mounted between a shaft hole of a support arm of a support stander of the zinc pot roller system and a shaft sleeve on a roll shaft. The wear-resisting bearing bush comprises a bearing bush main body, wherein the bearing bush main body consists of a stainless steel matrix, a ceramic inner sleeve and a sealing ring, the ceramic sleeve is sealed by the sealing ring and is fixed in the stainless steel matrix, and a stopping ring table for preventing the axial float of the roll shaft is arranged at the inner ring of the ceramic inner sleeve close to a seal head end of the shaft sleeve. The wear-resisting bearing bush has the advantages that the wearing of the shaft sleeve caused by the axial float of roll shaft is prevented by arranging the stopping ring table at the inner ring of the ceramic inner sleeve, so that the service life of the shaft sleeve is prolonged, the working stability of the zinc pot roller system is guaranteed, the equipment maintenance cost is lowered, and the yield of cold-rolling strip steel is improved.
Description
Technical field
The utility model relates to hot galvanizing production field equipment, refers to that particularly a kind of zinc pot roller is abrasion-proof bearing bush.
Background technique
In galvanization production line, because cold-strip steel can produce camber in process of production, namely with the edge of steel one side and departing from of straight line, like this, directly cause axial float and the vibration of zinc pot roller system.In production process, zinc pot roller is high-speed motion, and zinc pot roller system is in case axial float occurs and vibrate the violent friction that will cause the backstop wear-resistant block on roll shaft axle sleeve and catch arm.The material therefor of axle sleeve is common alloy type at present, be high hardness alloy class material and the backstop wear-resistant block adopts, axle sleeve and backstop wear-resistant block directly affect the stability of zinc pot roller system operation, for satisfying production requirement, axle sleeve may wear to a certain degree, must in time change.Both losses have been accelerated in the violent friction of roll shaft axle sleeve and backstop wear-resistant block, thereby have shortened working life, have strengthened the spending of spare parts and components.
Summary of the invention
The purpose of this utility model is exactly will overcome to have the defective that zinc pot roller is the abrasion-proof bearing bush existence now, provides a kind of and prevents that the zinc pot roller of axle sleeve and the wearing and tearing of backstop wear-resistant block from being abrasion-proof bearing bush.
For achieving the above object, the designed zinc pot roller of the utility model is abrasion-proof bearing bush, it is arranged between the axis hole and the axle sleeve on roll shaft that zinc pot roller is the frames support arm, its special way is: it comprises the bearing shell main body, described bearing shell body is comprised of stainless steel parent, ceramic inner sleeve and sealing ring, described ceramic inner sleeve is fixed in the stainless steel parent by the sealing ring block, and described ceramic inner sleeve is provided with by the inner ring of axle sleeve seal head end the baffle ring platform that prevents the roll shaft axial float.
The utility model has the advantage of: designed zinc pot roller is abrasion-proof bearing bush, the mode that the baffle ring platform is set by the inner ring in ceramic inner sleeve prevents that the roll shaft axial float from causing the wearing and tearing of axle sleeve, extend the working life of axle sleeve, guaranteed the stability when zinc pot roller is work, reduce cost of equipment maintenance, improved the yield rate of cold rolled strip steel production.
Description of drawings
Fig. 1 is the utility model is scheme of installation on frames at zinc pot roller.
Fig. 2 is the structure for amplifying schematic diagram of Fig. 1 intermediate bushing.
In figure, each parts label is as follows: bearing shell body 1(wherein: stainless steel parent 1.1, ceramic inner sleeve 1.2, sealing ring 1.3, baffle ring platform 1.4); Roll shaft 2; Axle sleeve 3; Support arm 4, catch arm 5.
Embodiment
In order to explain better the utility model, further illustrate main contents of the present utility model below in conjunction with specific embodiment, but content of the present utility model not only is confined to following examples.
Zinc pot roller as shown in Fig. 1 ~ 2 is abrasion-proof bearing bush, it is arranged between the axis hole and the axle sleeve 3 on roll shaft 2 that zinc pot roller is frames support arm 4, it comprises bearing shell main body 1, bearing shell body 1 is comprised of stainless steel parent 1.1, ceramic inner sleeve 1.2 and sealing ring 1.3, and ceramic inner sleeve 1.2 is fixed in stainless steel parent 1.1 by sealing ring 1.3 block.
For preventing that roll shaft 2 axial floats from making the violent friction of catch arm 5 that arranges on axle sleeve 3 and support arm 4 cause axle sleeve 3 wearing and tearing, pottery inner sleeve 1.2 is provided with baffle ring platform 1.4 by the inner ring of axle sleeve 3 seal head ends, limited the axial displacement of roll shaft 2, extend the working life of axle sleeve 3, guaranteed the stability when zinc pot roller is work, reduce cost of equipment maintenance, improved the yield rate of cold rolled strip steel production.
Claims (1)
1. a zinc pot roller is abrasion-proof bearing bush, it is arranged between the axis hole and the axle sleeve (3) on roll shaft (2) that zinc pot roller is frames support arm (4), it is characterized in that: it comprises bearing shell main body (1), described bearing shell body (1) is comprised of stainless steel parent (1.1), ceramic inner sleeve (1.2) and sealing ring (1.3), described ceramic inner sleeve (1.2) is fixed in stainless steel parent (1.1) by sealing ring (1.3) block, and described ceramic inner sleeve (1.2) is provided with by the inner ring of axle sleeve (3) seal head end the baffle ring platform (1.4) that prevents the roll shaft axial float.
