Abstract
The utility model discloses a last hanging bearing that uses of screw conveyer. It is composed of a suspension arm and a bearing body movably sleeved with the suspension arm. The bearing body is internally provided with a rolling bearing, an inner ring of the rolling bearing is inlaid on a connecting shaft and is positioned through an end cover, two sides of the connecting shaft are respectively provided with a flange plate connected with a spiral shaft of the conveyor, two outer sides of the bearing body are respectively tightly attached with a friction sealing ring, the ring is tightly pressed with the bearing body through a positioning sleeve and a flange plate which play a role of a blocking body, and a spring ring or a rubber ring is pressed between the friction sealing ring and the positioning sleeve or the flange plate. The utility model discloses hanger bearing sealing performance has been improved.
Description
The utility model relates to a kind of hanger bearing, is particularly useful for using on the screw conveyor.
In prior art, the hanger bearing that uses on the screw conveyor is by arm, bearing support, bearing in the bearing support and end cover constitute, junction plane between axle and the end cap adopts seal ring to realize motive sealing, seal ring places the seal groove in the end cap axis hole, its deficiency is that seal ring only depends on the elasticity of material own tightly to be enclosed within on the axle with certain pressure and seals, the pressure of hoop on axle reduces behind the ring wear, dust, moisture content in the working environment are entered in the bearing, make damage of bearings.In actual the use, this hanger bearing working life only is three months, mainly is because of due to the seal failure.Arm adopts with bearing support and fixedlys connected in addition, and is longer because of being hung the screw axis that connects, and when hanger bearing is hanging connected between the screw axis, makes axle and end cap combination surface unbalance stress, produces the slit, and ring wear is accelerated, and causes losing efficacy.
The purpose of this utility model is to provide a kind of hanger bearing that improves sealing configuration.
The purpose of this utility model is achieved in that hanger bearing comprises arm, the bearing support that is connected with arm, rolling bearing is arranged in the bearing support, its inner ring is set on the coupling shaft, the outer ring is by end cap and bearing support location, respectively there is a flange plate at the coupling shaft two ends, be used for being connected with the flange plate of screw axis end, one of them flange plate and coupling shaft are made of one, so that simple in structure.The bearing support both sides respectively are glued with a friction sealed ring, this ring compresses by block body and bearing support, elastic ring of crimping between friction sealed ring and block body, when friction sealed ring weares and teares, the pretightening force that is produced by elastic ring is compensated, guaranteeing that friction sealed ring necessarily compresses with sealed maintenance all the time contacts, and seals.Arm and bearing support pivot bush unit make between arm and the bearing support to have the gap, and hanger bearing is stressed when reducing because of screw axis and bearing support decentraction.
Advantage of the present utility model and good effect are: 1. friction sealed ring remains with sealing surface compact and contacts under block body and elastic ring positive action therebetween, has strengthened sealing, makes bearing bring up to 3 years from original three months working life; 2. adopt arm and bearing support pivot bush unit, the active force between when having reduced because of screw axis and bearing support decentraction is beneficial to the raising bearing life; 3. the friction sealed ring that seals places the bearing support outside, even coupling shaft and screw axis decentraction do not influence the sealing of friction sealed ring yet.
Accompanying drawing 1 is the hanger bearing structure diagram.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Referring to accompanying drawing, hanger bearing makes bearing support 2 relative suspension ring 14 make adaptability by arm 1, by suspension ring 14 and bearing support 2 pivot bush units, and is stressed to reduce hanger bearing.Two rolling bearings 3 are arranged in the bearing support 2, and its inner ring 4 is set on the coupling shaft 5, and outer ring 12 is by end cap 6 and bearing support 2 location.Coupling shaft 5 one ends have with it and are the flange plate 7 of one, and the other end is with flange plate 8, and flange plate 7,8 is used for being connected with flange plate on the screw axis.Flange plate 8 is made up of the two halves dish, and two halves dish endoporus is a square hole, and studding with connection two halves dish on flange plate 8 surfaces is the retaining ring 13 of one, as long as pull down retaining ring 13 like this, then flange plate 8 is just pulled down easily.Rolling bearing 3 one ends that are installed in the bearing support 2 are located by bearing support 2 and coupling shaft 5, and the other end is located by end cap 6.All be glued with seal ring 9 in bearing support 2 both sides, compress by setting sleeve 11 and the flange plate 7 that plays the block body effect, elastic ring 10 is defined as spring shackle, also can be rubber ring and place between setting sleeve 11, flange plate 7 and the friction sealed ring 9 generation pretightening force and friction compensation seal ring 9 abrasive actions.Setting sleeve 11, flange plate 7 are the conical surface with elastic ring 10 surface of contact, lose with minimizing elastic ring 10 pretightening forces on friction sealed ring 9 to guarantee elastic ring 10 stepless actions.When being hung the screw axis rotation that connects, drive setting sleeve 11, elastic ring 10, friction sealed ring 9 and bearing inner race 4 by flange plate 7 and flange plate 8 and rotate, friction sealed ring 9 rubs mutually with bearing support 2 two side ends, when because of the friction attenuation, under elastic ring 10 effects, compress all the time, keep good sealing.
