Abstract
The present invention discloses a bearing sealing structure filled with sealing grease, which is composed of a bearing, end covers, a bearing base and a shaft supported by the bearing, wherein the end covers arranged at both sides of the bearing are provided with hollow cylindrical bulges, sealing grooves are arranged on the inner walls of the bulges, and the sealing grooves are filled with sealing grease composed of 60 to 70% of general lithium base grease, 25 to 30% of antiaging agents and 5 to 10% of adhesive material. After filled with the sealing grease, the bearing sealing structure of the present invention has the advantages of good sealing adhesion performance, no wear, difficult aging and good sealing effect, and is suitable for rolling bearings and sliding bearings, particularly the sealing of electromechanical bearings and large equipment bearings used in mine adverse environment.
Description
The present invention be " a kind of seal gease and sealing configuration thereof that is used for bearing " application for a patent for invention divide an application original application day: April 25 calendar year 2001, application number 01115377.6, invention and created name: a kind of seal gease and sealing configuration thereof that is used for bearing.
Technical field
The present invention relates to a kind of electromechanical equipment bearing seal structure, the bearing seal structure of especially a kind of utilization " flexibility " seal gease.
Background technique
As everyone knows, in the electromechanical equipment bearing, traditional sealing configuration refers to that between sealing gasket and the bearing be that a kind of " rigidity " contacts, as the industrial felt pan that pressurizes at bearing shaft place, after axle turns round a period of time, felt pan is because operating temperature, the influence of factors such as acid and alkali corrosion deforms, and felt pan forms the gap with the axle surface, " applying " well, cause leaking or outside dust of internal lubricant, material, entering of steam, thus cause bearing lubrication bad, wearing and tearing aggravation or corrosion, influence the normal use of bearing, have small part to use felt pan instead rubber material, but unsurmountable wearing and tearing and deterioration phenomenon can cause seal failure.
Summary of the invention
The objective of the invention is in order to solve the defective of above-mentioned sealing configuration, utilize " flexibility " seal gease and sealing configuration thereof to replace " rigidity " sealing configuration, provide a kind of sealing configuration stickiness good, do not have wearing and tearing, be difficult for wearing out, have the bearing seal structure of excellent sealing effect.
For achieving the above object, the present invention has adopted following technological scheme: a kind of bearing seal structure that seal gease is housed, axle by bearing, end cap, bearing support and bearing supporting is formed, its characteristics are: be installed in the bearing end covers at two sides and have the hollow cylindrical projection, on described convex inner walls, have seal groove, be full of seal gease in the described seal groove.
Described convex inner walls has at least two seal grooves.
Be respectively equipped with lubricating cup on the described end cap; Anastomosis part between described end cap one side and the axle is provided with tapering.
Described hollow circuit cylinder endoporus cooperates with axle, at the circumferential annular seal groove of opening on the inner hole wall more than two, fill seal gease in the groove, seal groove has formed several roads sealing strip, and seal gease has stopped that fully entering of foreign object and oiling agent leak, because seal gease is a fat, amorphous, there are not wearing and tearing, be difficult for aging, can both close with axle " flexibility " card in any case, sealing effect is very good.
The seal gease that the present invention uses is made up of universal lithium base grease, antiageing agent and adhesive material, and its weight percentage is: universal lithium base grease 60%-70%, antiageing agent 25%-30%, adhesive material 5%-10%.
Described antiageing agent be in plumbago, calcium base complex grease, molybdenum disulfide, the calcium soda soap hydrocarbon solid one or both, described adhesive material is that bright stock or polyisobutylene are wherein a kind of.

Fig. 3 is an end cap I-I sectional drawing
Embodiment
As Fig. 1, Fig. 2, shown in Figure 3: bearing end covers at two sides 2 and 4 hollow circuit cylinder part endoporus match with axle 1, at several annular seal grooves of inner hole wall processing, minimum two, determine the degree of depth and the width of fluting according to the width of hollow circuit cylinder convex portion, general groove depth 3-8mm, groove width is greater than 3mm, be full of seal gease in the seal groove, seal gease will exceed bore area 2mm, the gap of axle 1 and end cap 2 and 4 endoporus is filled by seal gease 12,6 respectively, forms seal band, and minimum twice have played seal action effectively.The outer ring of bearing 9 is by the seam location of end cap 2 and 4, inner ring is by the shaft shoulder and positioning ring 8 location of axle 1, end cap 2 and 4 is fixing with bearing support 3 by bolt 10 and bolt 5 respectively, at axle 1 and end cap 4 mating parts tapering is arranged, if the lubricating grease of bearing 9 is during because of the heating desaturation, easily flow out, can also take the dirt of the inside out of, help the cleaning of bearing inside along the gap between end cap 4 and the axle 1.
The concrete preparation of seal gease is very convenient, be made up of universal lithium base grease, calcium soda soap hydrocarbon solid, molybdenum disulfide, polyisobutylene, its weight percentage is: by using lithium grease 65%, calcium soda soap hydrocarbon solid 20%, molybdenum disulfide 10%, polyisobutylene 5%.
The present invention all is suitable for rolling bearing and sliding bearing, is specially adapted to the sealing of various electromechanical equipment bearings, is particularly useful for the sealing of the main equipment bearing in the dust rugged environment of mine.
Claims (5)
