Abstract
The utility model discloses a durable roller, which comprises a fixing shaft and a cylinder body. The fixing shaft is arranged on the cylinder body through a bearing. The utility model is characterized in that the outer end of the bearing is provided with a sealing end cover. A sealing ring and a framework oil seal are respectively arranged between the sealing end cover and a bearing seat and the fixing shaft. A sealing mat is arranged between the inner end of the bearing and the bearing seat. Because the technical scheme is adopted by the utility model, when temperature changes, sealing parts arranged at the outer end of the bearing can generate relative displacement without influencing the sealing of the bearing and at the same time, dust and water is effectively prevented from entering the bearing, lubricant can not leak, and the service life of the bearing and the roller is prolonged.
Description
Technical field
The utility model belongs to the belt conveying machine equipment, is specifically related to a kind of carrying idler that is used for belt conveying equipment.
Background technology
At present, belt conveying equipment is widely used in the mass transport operation of factories and miness, station, harbour.This equipment is to utilize the carrying roller support belt, drive to carry by power and brings convey materials.The carrying roller that wherein plays the carrying effect is important parts.But there is serious sealing problem in existing carrying roller.
The sealing of existing carrying roller adopts the nylon 1010 seal ring to seal, and sealing property is not strong.At first, the sealed nylon circle can expand and shrink under the situation of being heated and catching a cold, and when expanded by heating, seal ring is in the swelling state with contacting of axle, makes seal ring be worn.When shrinking, produce the gap between the contact surface of seal ring and ram axle bearing and axle when catching a cold.The generation in gap causes the leakage of butter.Secondly, seal ring is to adopt labyrinth seal, can only prevent dust, can not waterproof, and glassware for drinking water has flowing power, can flow in the gap of seal ring, makes moisture can enter in the sealed chamber, on bearing, makes bearing generation corrosion.The leakage of butter and the corrosion of bearing cause bearing to rotate dumb and stuck phenomenon.Particularly use in the south of many high temperature, rainy water, it is impaired to make that more bearing quickens, and the roller skin is more easy to wear.Because sealing property is bad, causes the service life of carrying roller not long.
The utility model content
The purpose of this utility model provides a kind of good seal performance, the durable carrying roller of long service life.
Realize that the technical scheme that above-mentioned purpose adopts is:
Durable carrying roller of the present utility model comprises anchor shaft, cylindrical shell, and anchor shaft on cylindrical shell, is provided with end cover in the outer end of bearing by bearing installation, is respectively equipped with seal ring and outside framework oil seal between end cover and bearing seat and anchor shaft; Between the inner of bearing and bearing seat, be provided with packing seal.
The utility model is owing to adopted technique scheme, when temperature traverse, be located at and produce relative displacement between the sealing element of bearing outer end and do not influence sealing bearing, can effectively prevent simultaneously entering in the bearing of dust and water, and lubricating oil can not revealed yet, prolonged the service life of bearing, also prolonged the service life of carrying roller.
Further specify the technical solution of the utility model below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a running condition scheme drawing of the present utility model.
The specific embodiment
See Fig. 1, durable carrying roller comprises anchor shaft 10, cylindrical shell 3, bearing 8 is contained in the bearing seat 2 of cylindrical shell 3, anchor shaft 10 is installed on the cylindrical shell 3 by bearing 8, be provided with end cover 4 in the outer end of bearing 8, between end cover 4 and bearing seat 2 and anchor shaft 10, be respectively equipped with O RunddichtringO 5 and outside framework oil seal 6; Between the inner of bearing 8 and bearing seat 2, be provided with packing seal 9, end cover 4 usefulness circlip for bores 1 location, anchor shaft 10 adopts circlip for shafts 7 location with bearing 8.
The running condition of this durable carrying roller is seen Fig. 2, and durable carrying roller is fixed on the support 11 by the draw-in groove at axle 10 two ends, and it and general belt conveyer carrying roller have interchangeability.
