Abstract
The utility model relates to a high-sealed bearing of an automobile silicon oil fan clutch, which consists of a sealing element and a bearing inner ring sealing groove, wherein the sealing element (1) enters the bearing inner ring sealing groove (2) through press mounting, a sealing element upper lip (3) is arranged on the upper part of the sealing element (1), a sealing element lower lip (4) is arranged on the lower part of the sealing element (1), the sealing element upper lip (3) is closely approached to an actinal surface of the bearing inner ring sealing groove (2) under the effect of the working pressure of silicon oil, the sealing element lower lip (4) is simultaneously contacted with a stage surface of the bearing inner ring sealing groove (2), the sealing element (1) consists of acrylic rubber and a steel skeleton, and the steel skeleton (6) is arranged on the lower part inside the acrylic rubber (5). Due to the adoption of the high-sealed bearing of the automobile silicon oil fan clutch, the defect of the silicon oil leakage caused by the unfavorable sealing of the bearing can be effectively improved, the utilization rate of the bearing can be effectively improved, and the service life of an engine and a fan can be prolonged.
Description
Technical field: the utility model relates to bearing, particularly a kind of automobile silicon oil filled fan clutch high sealing bearing.
Background technique: domestic medium-sized and small enterprises stuffing box bearing sealing configuration adopts the contact seal bearing of nitrile compound and skeleton combination mostly, in the use because of very easily causing bearing seal bad after nitrile butadiene rubber resistance to high temperature and corrosion-resistant, the temperature rise, the silicone oil leakage phenomenon takes place, cause the clutch premature failure and cause motor to damage, the special construction of clutch in addition, bearing can't be changed, and finally causes product performance total failure, can not satisfy client's use, therefore long-term dependence on import.
Summary of the invention: the purpose of this utility model is to provide a kind of automobile silicon oil filled fan clutch high sealing bearing, utilize this bearing can improve the defective that causes silicone oil to leak because of bearing seal is bad effectively, can effectively improve the bearing utilization rate, prolong the life-span of motor and fan.
Formation of the present utility model: be made up of Sealing and bearing inner race seal groove, Sealing enters in the bearing inner race seal groove by press-fiting.
The Sealing upper lip is arranged on Sealing, the Sealing lower lip is arranged below, closely approaching with bearing inner race seal groove actinal surface at silicone oil working pressure effect lower seal upper lip, the Sealing lower lip contacts with bearing inner race seal groove step surface simultaneously.
Sealing is made of acrylate rubber and steel skeleton, and the steel skeleton is arranged on below in the acrylate rubber.
Compared with the prior art, Sealing epipharynx structure uniqueness of the present utility model, this sealing configuration advantage is: 1. during the bearing clutches, the air-flow that produces under clutch silicone oil working pressure can be discharged by Sealing upper lip and lower lips on the one hand, the Sealing upper lip of this moment can be closely more approaching with bearing inner race seal groove actinal surface under the effect of silicone oil working pressure on the other hand, makes that dustproof effect is better; 2. the Sealing lower lip contacts more tight with bearing inner race seal groove step surface simultaneously, prevented extraneous medium dust and silicone oil etc. to enter bearing inside on the one hand, having prevented the excessive of bearing internal lubrication fat on the other hand again. this Seal Design structure has solved and leakage of oil occurred because of bearing seal is bad and cause automobile silicon oil filled fan clutch assembly failure problem, has improved bearing, motor and fan working life.
The bearing seal performance improves, and its technical order is: (1) leaks the fat amount less than 0.04g, (2) air leakage test air pressure 0.035～0.045MPa, and bearing does not have gas leakage.
Description of drawings:
Accompanying drawing is the utility model structural representation.
Among the figure 1, Sealing, 2, the bearing inner race seal groove, 3, the Sealing upper lip, 4, the Sealing lower lip, 5, acrylate rubber, 6, the steel skeleton.
Embodiment:
Referring to accompanying drawing, formation of the present utility model: be made up of Sealing and bearing inner race seal groove, Sealing 1 enters in the bearing inner race seal groove 2 by press-fiting.
Sealing upper lip 3 is arranged on Sealing 1, Sealing lower lip 4 is arranged below, closely approaching with bearing inner race seal groove 2 actinal surfaces at silicone oil working pressure effect lower seal upper lip 3, Sealing lower lip 4 contacts with bearing inner race seal groove 2 step surfaces simultaneously.
