Abstract

The utility model relates to a seal structure of a roller bearing, in particular to an oiling roller structure. The oiling roller structure solves the problem that an existing seal structure of the roller bearing can not prevent outside dust particles from entering into lubricating cavities. The oiling roller structure comprises a roll shaft and a roller cover sleeved outside the roll shaft, wherein two bearings are respectively installed at the two ends of the roll shaft, inner rings of the two bearings are respectively sleeved outside the two ends of the roll shaft, two bearing seats are respectively installed on outer rings of the two bearings and respectively sleeved inside the two ends of the roll cover, two outer oil seals are respectively arranged on the outsides of the two bearings, the end faces of the inner sides of the two outer oil seals are respectively closely attached to the end faces of the outer sides of the two bearings, two separation sleeves are respectively installed on the inner sides of the two bearings, the end faces of the outer sides of the two separation sleeves are respectively closely attached to the end faces of the inner sides of the two bearings, inner cavities of the two separation sleeves respectively form two lubricating cavities, and two inner oil seals are respectively on the inner sides of the two separation sleeves. The oiling roller structure is applicable to sealing of the roller bearing.

Description

The oil filling idler structure

Technical field

The utility model relates to the hermetically-sealed construction of Idler bearing, specifically a kind of oil filling idler structure.

Background technology

Belt conveyer is indispensable important component part in the Detroit automation lane of traffic.As the core component of belt conveyer, can carrying roller normally move operation conditions and the running quality that is directly connected to belt conveyer.According to statistics, the reason of carrying roller operational failure 95% is because Idler bearing damages.Therefore, in order to guarantee the normal operation of carrying roller, need to seal Idler bearing by hermetically-sealed construction.At present, the roller bearing sealing structure mainly adopts contactless labyrinth seal structure.Practice shows that this kind hermetically-sealed construction can't stop extraneous dust granules to enter lubricating cavity because self structure is limit, and causes easily thus grease contaminated and wear-out of a bearing, and then causes the bearing use cost to improve and bearing shortening in service life.Based on this, be necessary to invent a kind of brand-new roller bearing sealing structure, can't stop extraneous dust granules to enter the problem of lubricating cavity to solve existing roller bearing sealing structure.

Summary of the invention

The problem that the utility model can't stop extraneous dust granules to enter lubricating cavity in order to solve existing roller bearing sealing structure provides a kind of oil filling idler structure.

The utility model is to adopt following technical scheme to realize: the oil filling idler structure comprises roll shaft and is coated at roller skin on the roll shaft; The two ends of roll shaft respectively are equipped with a bearing; The inner ring of two bearings is coated at respectively the two ends of roll shaft; The outer ring of two bearings respectively is equipped with a bearing seat; Two bearing seats are placed in the two ends of roller skin in respectively; The outside of two bearings respectively is equipped with an outer oil seal; The inner side end of two outer oil seal is close to respectively the outside end face of two bearings; The inboard of two bearings respectively is equipped with a spacer; The outside end face of two spacers is close to respectively the inner side end of two bearings; The inner chamber of two spacers consists of respectively two lubricating cavities; The inboard of two spacers respectively is equipped with an inner oil seal; The outside end face of two inner oil seals is close to respectively the inner side end of two spacers; The inner side end of two inner oil seals is close to respectively the outside end face of two bearing seats; Two outer oil seal, two spacers, two inner oil seals are placed in respectively on two bearing seats; Two bearing seats, two outer oil seal, two spacers, two inner oil seals all are coated on the roll shaft; Each offers an oil hole vertically on the both sides end face of roll shaft; The middle part of two oil holes is communicated with two lubricating cavities respectively; Be communicated with communicating pipe between the bottom of two oil holes; Communicating pipe is between roll shaft and roller skin.

During work, two outer oil seal and two inner oil seals form many lip seals of twice structure jointly.Many lip seals of twice structure can effectively be filtered the air that enters two lubricating cavities jointly, prevents that effectively dust granules from entering two lubricating cavities, effectively prevents grease contaminated and wear-out of a bearing thus.By two oil holes and communicating pipe can be to grease up in two lubricating cavities, with the internal cause gasification of supplemental lubrication chamber and mummification and the grease that reduces guarantees that thus two bearings are in good lubricating status.Based on said process, compare with existing roller bearing sealing structure, oil filling idler structure described in the utility model has effectively prevented grease contaminated and wear-out of a bearing by setting up many lip seals structure, and then effectively reduce the bearing use cost, effectively prolonged bearing service life.Simultaneously, oil filling idler structure described in the utility model has guaranteed that effectively bearing is in good lubricating status, and then has effectively prolonged the service life of bearing by setting up oil hole and communicating pipe.In sum, oil filling idler structure described in the utility model is based on brand new, efficiently solving existing roller bearing sealing structure can't stop extraneous dust granules to enter the problem of lubricating cavity, effectively improve the sealing effectiveness of Idler bearing, and then effectively guaranteed the normal operation of belt conveyer.

The utility model efficiently solves the problem that existing roller bearing sealing structure can't stop extraneous dust granules to enter lubricating cavity, is applicable to the sealing of Idler bearing.
