Abstract
The utility model relates to an oil filling type, high intensity rubber conveyor roller, belonging to a range of rubber conveyor; a plurality of protruding reinforcement ribs are arranged on an inner wall of the roller, and a groove is positioned on an outer wall of the bearing seat; a bearing is connected with the shaft; a clip spring is arranged at the external end of the bearing; a longitudinal blind hole is arranged at the center of the shaft; an oil filling valve is arranged at the opening end and a radial hole is arranged at the bearing location; the blind hole at the shaft center is communicated with one end of the radical hole; an oil channel is arranged at the other end of the radical holes; the oil channel is communicated with the clip groove, the oil channel is positioned at the outer surface of the shaft, and the terminal connection of the bearing seat is sealed. The utility model has the advantages that: firstly; less belt running resistance to reduce power consumption of the rubber belt conveyor; secondly; lightweight of the roller, small working intensity of fixation, dismantle, maintenance and operation; thirdly; filling of lubricant into bearing of the roller is available with good sealing effect of bearing and the service life is longer; fourthly; good abrasion resistance, static resistance and longer roller service life; fifthly; stable running of the roller and less noisy.
Description
Technical field
The utility model relates to a kind of idler of rubber tape conveyor, particularly a kind of oil-filling type high strength idler of rubber tape conveyor.
Background technology
At present, the idler of rubber tape conveyor of domestic production and use is to be made of roller supporting tube, bearing seat, bearing and axle, respectively connects a bearing seat and bearing at two ends of carrying roller, and axle passes the mesopore of two bearings.Wherein: roller supporting tube is the light tube, mainly uses steel pipe manufacturing, uses middle idler roller tube and bearing seat easy-to-rust; Axle is a solid axle, and the carrying roller own wt is heavy when constituting finished product, and rotary resistance is big, because the leak tightness of rotary part is poor, and can't refuel to bearing under the state of not disassembling carrying roller again, bearing portion easily advances dust during long-term work, cause bearing failure, reduced the service life of carrying roller.
Summary of the invention
The purpose of this utility model is that a kind of good airproof performance will be provided, again can be to bearing gas filed oil-filling type high strength idler of rubber tape conveyor under the state of not disassembling carrying roller.
The purpose of this utility model is achieved in that the reinforced rib that protrusion is arranged on the inwall of roller supporting tube; Fluted on the outer wall of bearing seat; On axle, be connected with bearing, there is jump ring outer end at bearing, at the center of axle blind hole is longitudinally arranged, open end has fuel feeding valve, at bearing portion radial hole is arranged, an end of radial hole communicates with the blind hole at axle center, at the other end of radial hole oil groove is arranged, oil groove communicates with the jump ring groove, and oil groove is positioned at the outside face of axle; Port at bearing seat is connected with sealing.
Beneficial effect: owing to adopt such scheme, be connected with sealing, can guarantee that bearing portion no longer enters dust, good airproof performance at the port of bearing seat; Communicate with bearing owing to porose on axle, butter can be injected in the bearing, can under the state of not disassembling carrying roller, refuel, reach the purpose of this utility model bearing by blind hole, radial hole, oil groove and jump ring groove.Advantage: the running resistance of (1) belt feeder is little, has reduced the load of travelling apron, has reduced the power consumption of travelling apron; (2) carrying roller is in light weight, and installation, dismounting, maintenance work intensity are little, easy to use; (3) can be to carrying roller rolling bearing position filling lubricating oil, the bearing portion good sealing effect, bearing prolongs service life greatly, has reduced the accident of travelling apron effectively; (4) roller supporting tube is owing to adopted high-strength polyvinyl chloride pipe for coal mine, and resistance to abrasion is good, and antistatic, and the carrying roller life-span is long; (5) this carrying roller operates steadily, noise is little, helps the healthy of workman.

Fig. 3 is bearing block structure figure of the present utility model.
Fig. 4 is axle construction figure of the present utility model.
The specific embodiment
Embodiment 1: the reinforced rib 2-1 that protrusion is arranged on the inwall of roller supporting tube 8; Fluted 3-2 on the outer wall of bearing seat; On axle 3, be connected with bearing 7, in the outer end of bearing jump ring 4 is arranged, blind hole 4-4 is longitudinally arranged at the center of axle 3, open end has fuel feeding valve 2, and fuel feeding valve has steel ball and spring 1, at bearing portion radial hole 4-3 is arranged, the end of radial hole 4-3 communicates with the blind hole 4-4 at axle center, the other end at radial hole 4-3 has oil groove 4-2, and oil groove 4-2 communicates with jump ring groove 4-1, and oil groove 4-2 is positioned at the outside face of axle 3; Port at bearing seat 6 is connected with sealing 5.On the inwall of the collar extension of bearing seat, sealed groove 3-1 is arranged, axis hole 3-3 is arranged in the bottom of bearing seat.
According to this scheme drawing pattern and structure, roller supporting tube, bearing seat adopt colliery high-strength polyvinyl chloride mold casting forming, and roller carrier shaft is designed to the formula of can refueling.Bearing, sealing member and the jump ring spring card that promptly rises is the outsourcing gauge member.This carrying roller can be made as the carrying roller of the different size that is applicable to that all size travelling apron uses.
