Abstract
The invention discloses a waterproof elevator bearing which comprises an outer ring, an inner ring, half retainers, steel balls, rivets, a sealing ring and a sealing ring framework. The outer circle of the bearing outer ring is matched with a steel wire rope hub, the inner circle of the bearing inner ring is matched with a shaft seat of an elevator car, and the steel balls are arranged between the outer ring and the inner ring; the outer ring can rotate around the inner ring through the steel balls, the two half retainers evenly divide the steel balls, and the half retainers are fixed through riveting of the rivets; the outer ring is provided with a sealing groove, the outer circle of the sealing ring is in interference fit with the sealing groove of the outer ring, and the sealing ring framework is arranged in the sealing ring. The waterproof elevator bearing is reasonable in design and convenient to use and machine; by improving the sealing structure of the sealing ring and the bearing inner ring, the technical problems that water is prone to entering an existing elevator bearing, and a sealing groove is prone to storing water during fire-fighting operation are solved, potential safety hazards in the using process of an elevator are reduced, and life and property safety of people is guaranteed.
Description
Technical field
The present invention is specifically related to a kind of waterproof elevator bearing.
Background technique
Elevator is as the special mechanical being related to the people's livelihood, and its safety problem is one of hot issue of social concerns always.Due to the Environmental Conditions that elevator is special, when security against fire is elevator design always, need the major issue considered.As elevator auxiliary products---bearing, the quality of its water-proof performance, drastically influence the normal use of elevator.The elevator bearing seal structure that existing market uses is roughly divided into two kinds, be a bearing seal structure for inner ring rib light trap limit design, this sealing configuration easily causes when fire-fighting operation, and water enters Bearing inner along bearing inner race rib, cause bearing failure, affect elevator safety; Another kind of is the design of inner ring fluting, and this design sealability comparatively light trap limit design wants excellent, but seal groove easily causes liquid storage, the use hidden danger causing Bearing inner to intake.
Summary of the invention
The object of the invention is, for solving above-mentioned deficiency, to provide a kind of waterproof elevator bearing.
The object of the invention is to be achieved through the following technical solutions:
A kind of waterproof elevator bearing, comprise outer ring, inner ring, half retainer, steel ball, rivet, seal ring and seal ring skeleton, bearing outer ring cylindrical coordinates with wire rope wheel hub, bearing inner race inner circle coordinates with elevator box axle bed, steel ball is had between outer ring and inner ring, outer ring can rely on steel ball to rotate around inner ring, two and half retainers are by steel ball even partition, half retainer is fixed by closing-up, outer ring is provided with seal groove, seal ring with outer and outer ring seal groove interference fit, seal ring skeleton is arranged on seal ring inside.
Inner ring cylindrical is provided with capillary groove.
Seal ring is provided with the first sealing lip and the second sealing lip, and the second sealing lip coordinates with capillary groove, and the first sealing lip and inner ring rib have gap.
The present invention has effect useful as follows:
The present invention is reasonable in design, easy to use, easy to process, by the improvement to seal ring and bearing inner race sealing configuration, solve the inner easily water inlet when fire-fighting operation of current existing elevator bearing, the technical problems such as the easy water of seal groove, decrease elevator potential safety hazard in use, ensure people life property safety.
Accompanying drawing explanation
Fig. 1 is side-looking overall structure schematic diagram of the present invention;
Fig. 2 is plan structure schematic diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated:
As shown in Figure 1, a kind of waterproof elevator bearing, comprise outer ring 1, inner ring 2, half retainer 3, steel ball 4, rivet 5, seal ring 6 and seal ring skeleton 8, bearing outer ring 1 cylindrical coordinates with wire rope wheel hub, bearing inner race 2 inner circle coordinates with elevator box axle bed, steel ball 4 is had between outer ring 1 and inner ring 2, outer ring 1 can rely on steel ball 4 to rotate around inner ring, two and half retainers 3 are by steel ball 4 even partition, half retainer 3 is fixed by rivet 5 riveted, outer ring 1 is provided with seal groove, seal ring 6 cylindrical and outer ring 1 seal groove interference fit, it is inner that seal ring skeleton 8 is arranged on seal ring 6.
Inner ring cylindrical is provided with capillary groove 7.
Seal ring is provided with the first sealing lip 9 and the second sealing lip 10, second sealing lip 10 coordinates with capillary groove, and the first sealing lip and inner ring rib have gap.
Bearing sealed ring is provided with the first sealing lip, and the first sealing lip and bearing inner race rib have gap, when bearing operation, Bearing inner lubricant oil oil pressure increases, and can extrude the first sealing lip, itself and bearing inner race rib are closely cooperated, improve sealability, prevent lubricant oil from overflowing; Bearing inner race is provided with capillary groove, second sealing lip and capillary groove closely cooperate, when bearing carries out fire control acceptance, Bearing outer hydraulic pressure is larger, the coordinate force of the second sealing lip and capillary groove is also larger, and bearing seal performance is better, and unnecessary moisture can be overflowed by seal groove, can not Bearing inner be entered, thus make bearing reach water-proof performance requirement.
Claims (3)
1. a waterproof elevator bearing, comprise outer ring, inner ring, half retainer, steel ball, rivet, seal ring and seal ring skeleton, it is characterized in that: bearing outer ring cylindrical coordinates with wire rope wheel hub, bearing inner race inner circle coordinates with elevator box axle bed, steel ball is had between outer ring and inner ring, outer ring can rely on steel ball to rotate around inner ring, two and half retainers are by steel ball even partition, half retainer is fixed by closing-up, outer ring is provided with seal groove, seal ring with outer and outer ring seal groove interference fit, seal ring skeleton is arranged on seal ring inside.
2. a kind of waterproof elevator bearing according to claim 1, is characterized in that: described inner ring cylindrical is provided with capillary groove.
3. a kind of waterproof elevator bearing according to claim 1 and 2, is characterized in that: described seal ring is provided with the first sealing lip and the second sealing lip, and the second sealing lip coordinates with capillary groove, and the first sealing lip and inner ring rib have gap.
