Existing " a kind of novel idler for belt conveyer device " (patent No. 02256608) a kind of novel idler for belt conveyer device, it has carrying roller, also is provided with cold drawn steel axle, watt oblique crank Z bearing, semi-enclosed bearing and labyrinth; Watt oblique crank Z bearing corresponding intrument is on the carrying roller internal orifice, semi-enclosed bearing closed end installs inwardly in the bearing seat axis hole, the labyrinth coalignment and is provided with the bulge loop of the location bearing inner ring that extends internally near the axis hole end on the labyrinth in hole, labyrinth, bearing seat outer end; The cold drawn steel shaft device is on the axis hole of bearing and labyrinth." a kind of Idler bearing inner seal liner press-loading head " (patent No. 01236320), body shape is cylindric, circular shaft through hole along its axis is divided into two sections that join, one section long diameter is identical with oil cylinder push rod diameter, one section short diameter is identical with roller carrier shaft 4 diameters, and the press-loading head end face circumferential edge that can insert roller carrier shaft one end is provided with circular convex edge.Can exactly the bearing inner seal liner in the two-piece-dress laminated type bearing seal be press-fit into place." a kind of carrying roller " (patent No. 96209784) comprises protective cover, cover cap, axle, back-up ring, roller shell, bearing seat, inner court sealing, the sealing of outer palace, bearing, protecting cover 1.The interior ring of the positioning table of back-up ring, protective cover, interior labyrinth packing and bearing joins successively, is contained on the axle, and with the axle close fit, be the fixed part of carrying roller.Cover cap, bearing seat, outer labyrinth packing, outer race and protecting cover and roller shell are close fit, are the rotating elements of carrying roller, and its bottom bracket is captiveed joint with the roller shell.
O-ring seal institute has been arranged pressure cooker so that pot inner high voltage gas external leakage not; Seal ring in the hydrostatic drive can make the shaft extension in the high-voltage oil cylinder contract freely and be oil tight; The S. A. of retarder, change speed gear box has had seal ring that the lubricating oil in the case is not exosmosed.Also not with the sealing of O-ring seal as idler for belt conveyer.
The summary of the invention the purpose of this utility model is at above-mentioned present situation, aim to provide and a kind ofly can thoroughly cut off extraneous rainwater, dust enters bearing bore in-to-in passage, bearing bore in-to-in grease can not outbound flow, bearing long service life, the band conveyor sealing idler roller that cost is low.
The implementation of the utility model purpose is, band conveyor sealing idler roller, antifriction-bearing box 3 are contained in the bearing seat 6, and axle 1 passes antifriction-bearing box 3, bearing seat 6, inside and outside O- ring seal 2,4 arranged in that antifriction-bearing box 3 is inside and outside, and outer gland sealing cushion rubber 4 is outer dust-proof cushion 5.
The utility model will revolve on the bearing felt that the shaft type lip-type packing is transplanted to the belt feeder carrying roller, and antifriction-bearing box 3 is inside and outside that O-ring seal all arranged, cut off extraneous rainwater, dust and entered passage in the bearing bore, sealing effectiveness is significantly improved, and bearing life can prolong 1-2 doubly.Lip-type packing has the very big lip of resilience, the banding spring make lip to axle have follow preferably compensatory, the diametral load of less lip is comprising axle all the time, the gapped sealing at original general axle and the relative motion position of sealing member is become gap-free sealed, thereby obtained the better seal effect.
Appended drawings is the utility model structural representation
The specific embodiment is with reference to accompanying drawing, and the utility model revolves the inside and outside lip packing cushion rubber 2,4 of shaft type antifriction-bearing box 3 inside and outside placement good seal performance.Inside and outsidely all seal, cut off extraneous rainwater, dust enters the passage in the bearing bore, sealing effectiveness is significantly improved, but bearing life director 1-2 doubly.
It becomes the gapped sealing at original general axle and the relative motion position of sealing member gap-free sealed.Lip-type packing has the very big lip of resilience, and all banding springs 7 of lip-type packing itself make lip have the diametral load of following compensatory, less lip preferably to axle all the time axle 1 to be comprised, thereby have obtained the better seal effect.Just as people's lip is containing the chopsticks of having a meal, even soup is arranged in the mouth, chopsticks pass in and out in mouth or when rotating, soup can not flow out outside the mouth yet.So thoroughly cut off extraneous rainwater, dust enters bearing bore in-to-in passage, simultaneously, bearing bore in-to-in grease can not outbound flow yet, guarantee grease not only totally but also sufficient lubricating bearings in bearing bore, bearing life is prolonged, and has reduced the stuck possibility of not changeing of belt feeder carrying roller to greatest extent.
