Abstract

The utility model relates to a carrier roller of the belt conveyer, which comprises a flexible shaft, a rubber roller and a hang box. A flexibleness mandrel is arranged on the flexible shaft, a layer of wrapper made of elastic materials is covered on the mandrel, a plurality of column-shaped rubber rollers are arranged on the flexible shaft, interstices are arranged among the rubber roller, and end shafts arranged on both ends of the flexible shaft is connected with the hang box body through a bearing. An arc-shaped groove can be automatically formed when the carrier roller of the belt conveyer is in use. The utility model has the advantages of simple structure, little metallic material consumption, large load, shock resistance, and low noise. The cost performance is apparently higher than various existing carrier roller.

Description

Pulley of belt conveyer

The utility model relates to a kind of roller that cooperates with the roller-way mechanical conveyor, is specifically a kind ofly to be made up of some rollers, is contained in the roller on the single axle.

Common carrying roller is the flute profile carrying roller, generally is made up of three independent roller elements, and the axis of three rollers becomes broken line.The complex structure of this carrying roller and carriage, carrying roller and load-transfer device contact wire can not form the nature camber line.Spring-loaded idler is a kind of novel carrying roller of function admirable, structure is simpler, simple installation, utilize the pressure of spring, pull-shaped change can make carrying roller and load-transfer device become the nature camber line to contact, its major defect is that the metallic material consumption of roll body is big, the mechanical property of materials is required height, and service life is shorter, and cost is higher.

The purpose of this utility model is to provide a kind of novel carrying roller, and it is simple in structure both to have had a spring-loaded idler, can overcome the deficiency of existing various carrying rollers again from advantages such as cambers.

This carrying roller is by flexible axle, and rubber roll and extension box are formed, and flexible axle is provided with flexible mandrel, and the outside of mandrel wraps tightly one deck elastomeric material, and the two ends of mandrel are connected with two end axles respectively.The several cylinders of arranging on flexible axle shape rubber roll, the centre hole and the flexible shaft jacket of rubber roll are closely connected, and leave the gap between the rubber roll.End beam warp bearing frame is held in to be hung in the box body.

The hook of carrying roller two ends extension box colludes on carriage during use, and load-transfer device contacts with the Elastic Cylindrical rubber roll, has deep-slotted chip breaker of one's own.The flexible core bearing is subjected to load, and the bearing interior with hanging box by the end axle is connected, and can guarantee the flexible rotation of carrying roller.

The flexible mandrel of flexible axle can be made with cable wire or round-link chain.

Distance between the control rubber roll makes rubber roll in carrying roller stand under load rotation process longitudinal travel not take place, can be provided with annular protrusion on flexible axle, and annular protrusion is in flexible axle and rubber roll joint portion, is provided with cooresponding circular groove on the center bore inner wall of rubber roll.Can be provided with the axle sleeve that elastomeric material is made between rubber roll and the rubber roll, the inside and outside outline line of axle sleeve axial cross section is the concave arc wire.The compression or the tensile deformation of axle sleeve when this design plan of axle sleeve helps the carrying roller rotation.

Rubber roll is made with rubber or plastics withstand voltage, wear-resisting, acid and alkali-resistance.

Below in conjunction with drawings and Examples, the utility model is described in further detail.

Fig. 1 is the carrying roller outside drawing.

Fig. 2 is the carrying roller longitudinal section view.

Fig. 3 is the carrying roller axial, cross-sectional view with annular positioning groove and axle sleeve.

Fig. 4 is the end axle and hangs the box constructional drawing.

The extension box 2 at flexible axle 1 two ends colludes on carriage 3 among Fig. 1, and several rubber rolls 4 of arranging on the flexible axle 1 leave the gap between the rubber roll 4, and 5 of belts are held on the rubber roll 4, have deep-slotted chip breaker of one's own.

Fig. 2 is the longitudinal section view of carrying roller, and cable wire 6 is the mandrel of flexible axle 1, bears main load, and cable wire 6 outside foreskins 7 are wrapped tightly by flexible material and form, and rubber roll 4 wraps tightly on the foreskin 7 of flexible axle 1.

Flexible axle 1 is provided with recessed 8 of annular among Fig. 3, is used for the location of rubber roll 4, is provided with axle sleeve 9 between the rubber roll 4, and axle sleeve 9 is the concave arc line with the axial transversal of flexible axle 1 joint portion, and the external shaft of axle sleeve 9 also is the concave arc line to transversal.

Fig. 4 display end axle is connected with the extension box, in cable wire (mandrel) 6 insertion end axles 10 1 stomidiums, forms a fixed connection after extruding.End axle 10 other ends are held in through 11 of two pairs of thrust barings and hang in the box 12, and gland 13 is fixed with hanging box 12 screw threads, seals simultaneously.Shaft end nut 13 is used to hold the fixing of axle 10 and bearing 11.

The utility model is simple in structure, and is in light weight, saves steel, and noise is very low in the use procedure, and belt is sideslip not, and is non-slip, and Roller Service Life is long, and load is big, and is shock-resistant, easy to maintenance, and the ratio of performance to price is apparently higher than existing all kinds of carrying rollers.
