Description
[technical field]
The present invention relates to technical field of bearings, specifically the present invention relates to a kind of grease lubrication stuffing box bearing.
[background technique]
Known, grease lubricating bearing enters in order to prevent dust, bits end, cutting fluid etc., conventionally adopts the dust cover of conventional construction or seal ring to carry out the Internal and external cycle of stuffing box bearing, and for high speed, long-life bearing, the inner space of bearing is relatively little, fills out fat amount few, and the life-span is short; Owing to producing larger heat when bearing runs up, and the dust cover surface area of conventional construction is little, and heat radiation and cooling effect are poor, thereby affect the life-span of bearing.
[summary of the invention]
In order to overcome the deficiency in background technique, the invention discloses a kind of grease lubrication stuffing box bearing, described grease lubrication stuffing box bearing is by by the arranged outside boss 10 of dust cover 5, and the inside of described boss 10 is provided with the groove 9 of hollow-core construction, and what effectively increased bearing fills out fat space; The present invention, due to the dust cover 5 arranging with boss 10, has increased the surface area of bearing, has effectively improved the life-span of radiating effect and the bearing of bearing.
For achieving the above object, the present invention adopts following technological scheme:
A kind of grease lubrication stuffing box bearing, comprise outer ring, inner ring, rolling element, retainer and dust cover, outside at inner ring is provided with outer ring, rolling element is arranged in the raceway between inner ring and outer ring, described retainer is separated rolling element uniformly, and the both sides between inner ring and outer ring are respectively equipped with dust cover, and the inner side of described dust cover is provided with positioning block, in dust cover outside, be provided with the boss that protrudes outer ring and inner ring end face, in the inside of boss, be provided with the groove of hollow-core construction.
Described grease lubrication stuffing box bearing, is respectively equipped with dustproof groove in the both sides of inner surface.
Described grease lubrication stuffing box bearing is provided with the spring ring of fixing dust cover in dustproof groove.
Described grease lubrication stuffing box bearing, described rolling element is steel ball.
Described grease lubrication stuffing box bearing, described retainer adopts two half retainers to be riveted together.
Described grease lubrication stuffing box bearing, described dust cover is steel material.
Owing to having adopted technique scheme, the present invention has following superiority:
Grease lubrication stuffing box bearing of the present invention passes through the arranged outside boss 10 of dust cover 5, the inside of described boss 10 is provided with the groove 9 of hollow-core construction, increased the surface area of bearing, what effectively increased bearing fills out fat space, thereby increase the fat amount of filling out of bearing, lubricating grease simultaneously that extrude from raceway groove in the time of can storing bearing operation, and realize the circulation of lubricating grease between raceway groove and dust cover, improve lubricating condition, improve the life-span of bearing.
