Abstract
The present invention discloses a machinery carrying roller of a band conveyer, which comprises a metal pipe body, a rotary shaft and a bearing seat. The machinery carrying roller of a band conveyer is characterized in that the bearing seat is made of plastics and is pressed in both ends of the metal pipe body in an interference fit mode. The machinery carrying roller of a band conveyer has the characteristics of novel structure, light weight and larger plastic plasticity utilization rate. When the plastic bearing seat is pressed in both ends of the metal pipe body in interference, the metal pipe body of which the original roundness is not up to requirements rises up. In this way, most of out-of-roundness of the metal pipe body can be eliminated, which enables the radial round jump to be reduced.
Description
Technical field:
The present invention relates to a kind of driving device, especially a kind of belt conveying machinery carrying roller.
Background technology:
At present, the main production method of belt conveying machinery carrying roller has two kinds, a kind of is at steel pipe two ends processing step hole, then bearing seat is pressed in the stepped hole, because leave certain stock left for machining, so must adopt the thicker steel pipe of tube wall just can meet the demands, cause the weight of carrying roller bigger, in addition because all there is certain out of roundness in steel pipe itself, want to guarantee that it is the comparison difficulty that steel pipe two ends stepped hole has higher concentricity, even adopt the stepped hole at a clamping processing of special specialized equipment steel pipe two ends, also be difficult to eliminate the out of roundness of outer diameter of steel pipes, productive costs is improved.Another kind method is to adopt the ram axle bearing, with the steel pipe cylindrical is benchmark, at both ends is in the face of the welding of back, position, so just can adopt the thin steel pipe of tube wall, thereby alleviate the weight of carrying roller, but also can not eliminate the out of roundness of steel pipe itself during welding,, more be difficult to guarantee the concentricity of steel pipe two end axles bearing in addition owing to errors that factor produced such as frock and welding deformations.
Summary of the invention:
It is lighter to the purpose of this invention is to provide a kind of weight, can effectively guarantee the belt conveying machinery carrying roller that metal body two end axles bearing concentricity and cylindrical radial run-out are little.
Technical scheme of the present invention is: a kind of belt conveying machinery carrying roller, comprise the metal body, and rotating shaft and bearing seat, bearing seat adopt plastics to make and adopt interference fit method to be pressed into the two ends of metal body.
In the middle of the metal body, adopt interference fit method to be pressed into more than one round plastic supporter, have at the middle part of round plastic supporter and wear axis hole.
On the top and bottom of round plastic supporter, have groove.
The thickness of pipe of metal body is 1.5～3.5mm.
The present invention has following advantage:
1, can save the manufacturing procedure of existing idler pipe two ends processing step hole or welding bearing seat, so just can eliminate the error in the manufacturing procedure, thereby labour intensity and productive costs are reduced greatly.
2, utilize the big characteristics of plastics plasticity, when the interference of plastic shaft bearing is pressed into metal body two ends, with the metal body of the inaccessible requirement of the original circularity circle that rises, can eliminate most of out of roundness that metal body itself exists like this, the radial run-out of carrying roller is reduced greatly.
3, directly utilize the raw steel inside pipe wall to be benchmark, saved the remanufacturing operation, adopt interference fit method the plastic shaft bearing to be pressed into the two ends of metal body, so just can improve the right alignment of body bearings at both ends, make carrying roller rotate flexible rotational resistance and reduce, the conformability of precision in the time of also can guaranteeing the carrying roller assembling simultaneously.
4, owing to adopt the thin-wall metal body, the weight of carrying roller is reduced greatly, the rotor inertia of carrying roller is reduced, thereby reduce kinetic equation loss greatly.
5, in order further to eliminate the out of roundness of metal body, in the middle of idler pipe, be pressed into the round plastic supporter about every interval 150mm, make most of elimination of out of roundness of whole body.
6,, thereby alleviate the weight of whole carrying roller in order to alleviate the weight of round plastic supporter, thereon below on have groove.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
The specific embodiment:
Structure of the present invention as shown in Figure 1, comprise metal body pipe 8, rotating shaft 10 and two plastic shaft bearings 7 that are contained in metal body 8 two ends, plastic shaft bearing 7 adopts interference fit with the inwall of metal body 8, in metal body 8, assemble a round plastic supporter 9 every 150mm, fluted 11 on the upper and lower surface of round plastic supporter 9, the inwall interference fit of it and metal body 8.The thickness of pipe of metal body 8 is 1.5～3.5mm, adopts sealing member 1,2,3,4 to seal in the two ends of carrying roller.
The present invention utilizes the big characteristics of plastics plasticity that plastic shaft bearing 7 and metal body 8 internal diameters are guaranteed have the bigger magnitude of interference to assemble, the out of roundness that makes metal body 8 is along with bearing seat 7 produces sex change, thereby and with supporter 9 also by the method production of bearing seat 7 and be assemblied in the middle of the metal body radial run-out that circle that metallic steel body 8 risen improves the right alignment of carrying roller bearings at both ends and reduces whole carrying roller, reduce the rotational resistance and the kinetic equation loss of carrying roller.
