Abstract
The utility model discloses a plastic carrier roller with strong bearing capacity, belongs to the technical field of transmission machinery, and particularly discloses a carrier roller of a belt conveyor. According to the structure of a carrier roller main body composed of a carrier roller shaft, a carrier roller bearing, a bearing support, a bearing baffle and a carrier roller drum, the outer surface of the carrier roller drum is equidistantly wavy, concave-convex grooves which are in close fit mutually are formed in the junction of the outer circle of the bearing support and the inner circle of the carrier roller drum, and concave-convex grooves in the outer circle of the bearing baffle coincide with the concave-convex grooves in the outer circle of the bearing support. Due to the fact that the outer surface of the carrier roller drum is equidistantly wavy, friction between the surface of the carrier roller drum and a conveying belt is increased. The concave-convex grooves between the carrier roller drum and the bearing support are adopted to increase the binding force of a stressed part, so that the carrier roller is steady in operation, low in noise, flexible in rotation, good in bearing performance, resistant to wearing and aging, better in using effect and longer in service life. Meanwhile, using cost is reduced and effectiveness is remarkable.
Description
Technical field
The utility model belongs to the gearing technical field, particularly a kind of belt conveyor carrying roller.
Background technology
At present, belt conveyer is widely used in the factories and miness material is carried, and the quality of critical component carrying roller directly affects the operation conditions of transmission apparatus.Domestic carrying roller commonly used is divided into three kinds of common carrying rollers, full nylon carrying roller, carrier roller by material.But in some common carrying rollers are used, because the wearing and tearing of carrying roller surface long term make friction force, descend, carrying roller can not normal rotation, to such an extent as to transmission efficiency reduces, finally causes carrying roller to damage.Therefore, improving structure on common carrying roller is very necessary to increase stressed skin friction force.
Summary of the invention
The purpose of this utility model is that a kind of cost of design is low, few to the adhesive tape wearing and tearing, the conveyer carrying roller that transmission efficiency is high.
The technical solution of the utility model is: in the carrying roller agent structure formed at roller carrier shaft, Idler bearing, bearing support, bearing baffle and roller supporting tube, the outside face of roller supporting tube is equidistant heave of the sea shape, be provided with mutual close-fitting concavo-convex groove at bearing support cylindrical and roller supporting tube inner circle joint portion, the bearing baffle cylindrical arranges consistent with the concavo-convex groove of bearing support cylindrical.
The beneficial effects of the utility model: the utility model utilizes the equidistant heave of the sea structure on roller supporting tube surface to increase the friction force between roller supporting tube surface and belt conveyor, utilize the binding force of the concavo-convex groove increase stressed member between roller supporting tube and bearing support, make carrying roller not only there are smooth running, characteristics that noise is low, also have and rotate the advantages such as flexible, that bearing is good, wear-resistant, ageing-resistant, result of use is better, and the life-span is longer.Use cost reduces simultaneously, and benefit is obvious.
The accompanying drawing explanation
Accompanying drawing 1 is the utility model cross-sectional view.
Accompanying drawing 2 is the utility model A-A cross-sectional view.
The specific embodiment
As shown in Figure 1, roller carrier shaft 1 of the present utility model, bearing 7 use the 35# steel to make, and idler pulley cylinder 5, bearing support 4, bearing baffle 3 all adopt the high molecule plastic material to make.Rubber seal 1 center hole is stuck in roller carrier shaft 1 groove, and outer circular edge is close to bearing baffle 3, plays dustproof, moisture seal effect.
As shown in Figure 2, the outside face of roller supporting tube 5 is equidistant heave of the sea shape, to increase the friction force between roller supporting tube 5 and feed belt, carrying roller is rotated more flexible.
Be provided with mutual close-fitting concavo-convex groove 6 at bearing support 4 cylindricals and roller supporting tube 5 inner circle joint portions, make combination between the two tightr, increased weight capacity and the whole firmness degree of carrying roller.
It is consistent that bearing baffle 3 cylindricals and the concavo-convex groove of bearing support 4 cylindricals arrange, bonding with sealant between bearing baffle 3 cylindricals and roller supporting tube 5 inner circles.
Claims (1)
1. a powerful bearing plastic carrying roller, in the carrying roller agent structure formed at roller carrier shaft (1), Idler bearing (7), bearing support (4), bearing baffle (3) and roller supporting tube (5), it is characterized in that: the outside face of roller supporting tube (5) is equidistant heave of the sea shape, be provided with mutual close-fitting concavo-convex groove at bearing support (4) cylindrical and roller supporting tube (5) inner circle joint portion (6), bearing baffle (3) cylindrical arranges consistent with the concavo-convex groove of bearing support (4) cylindrical.
