Description
Technical field
The utility model modified line formula total contact type belt idler belongs to the idler for belt conveyer technical field.
Background technology
Band conveyor is widely used in industries such as mine, harbour, thermal powerplant and building materials as a kind of material transfer equipment, application and extensive.The band conveyor important component part is a carrying roller, and the quality of carrying roller quality directly has influence on the service life of adhesive tape, and carrying roller performance quality has determined the performance of band conveyor.Carrying roller roller on the existing band conveyor is cylindrical, hinged the forming of carrying roller roller by three pitch circle cylindricalitys, the upper sideline of hinged back three carrying roller rollers is down echelon form, adhesive tape is circular-arc along carrying roller, so just caused that adhesive tape contacts fully with the non-of carrying roller under the light condition, thereby formed the tolerance clearance of two place's symmetries.When the material of being carried is filled adhesive tape, promptly under heavily loaded situation,, make the upper sideline of carrying roller contact fully with the adhesive tape back side owing to be subjected to the effect of material gravity, adhesive tape is not in a running state preferably all the time.Because adhesive tape changes structure, unreasonable and unscientific operation for a long time, make that operating adhesive tape quality descends obviously, shorten service life greatly.According to scene use experience for many years, phenomenon will appear damaging in a brand new adhesive tape, its period of service about 5 months.
The utility model content
For overcoming the deficiencies in the prior art, the modified line formula total contact type belt idler that the utility model provides a kind of carrying roller shape and adhesive tape curved shape to adapt can effectively prolong service life of adhesive tape.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: modified line formula total contact type belt idler, comprise: middle roller and two side rollers, middle roller and two sides are installed together by adapter shaft with roller, and the both sides of roller in the middle of two sides are positioned at roller, middle roller is the left-right symmetric structure, the centre is a cylindrical part, both sides are for increasing the conical portion of diameter gradually, the outside of two conical portions of middle roller is provided with cylindrical edge, similar dumbbell structure, and the diameter of the cylindrical edge of roller equates with the maximum gauge of conical portion in the middle of described, and the cylindrical part of described middle roller equates with the minimum diameter of conical portion;
The both sides of roller in the middle of two identical in structure sides are arranged symmetrically in roller, side is a conical portion with the part of the close middle roller of roller, the arranged outside of conical portion maximum gauge has cylindrical edge, and the cylindrical edge of side usefulness roller is adjacent with the cylindrical edge of middle roller, the outside of conical portion minimum diameter is a cylindrical part, similar horn-like structure, and described side equates with the maximum gauge of conical portion that with the diameter of the cylindrical edge of roller described side equates with the minimum diameter of conical portion with the cylindrical part of roller;
The utility model is compared the beneficial effect that has with prior art:
The centre of roller in the middle of the cylindrical part of the middle roller of the utility model modified line formula total contact type belt idler is positioned at, the both sides of middle roller cylindrical part are for increasing the conical portion of diameter gradually, the outside of two conical portions is provided with cylindrical edge, the conical portion that side with roller near the part of middle roller is, the arranged outside of conical portion maximum gauge has cylindrical edge, and the outside of conical portion minimum diameter is a cylindrical part; When middle roller and side fit together by adapter shaft with roller, upper sideline is shaped as a circular arc, identical with the curved shape of the adhesive tape that is positioned at its top, adhesive tape is in a good running state all the time during operation, cylindrical edge has changed the contact form of traditional adhesive tape and carrying roller roller joint portion, change the overall linear contact into by original part contact, because the utility model modified line formula total contact type belt idler can not change the structure and the performance of adhesive tape in use, so prolonged the service life of adhesive tape.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1 be middle roller, 2 for side with roller, 3 for adhesive tape, 4 for material, 5 for adapter shaft, 6 for cylindrical edge.
The specific embodiment
As shown in Figure 1, modified line formula total contact type belt idler, comprise: middle roller 1 and two side rollers 2, middle roller 1 and two sides are installed together by adapter shaft 5 with roller 2, and the both sides of roller 1 in the middle of two sides are positioned at roller 2, middle roller 1 is the left-right symmetric structure, the centre is a cylindrical part, both sides are for increasing the conical portion of diameter gradually, the outside of two conical portions of middle roller 1 is provided with cylindrical edge 6, similar dumbbell structure, and the diameter of the cylindrical edge 6 of roller 1 equates that with the maximum gauge of conical portion the cylindrical part of described middle roller 1 equates with the minimum diameter of conical portion in the middle of described;
The both sides of roller 1 in the middle of two identical in structure sides are arranged symmetrically in roller 2, side is a conical portion with the part of roller 2 close middle rollers 1, the arranged outside of conical portion maximum gauge has cylindrical edge 7, and side is adjacent with the cylindrical edge 7 of middle roller 1 with the cylindrical edge 7 of roller 2, the outside of conical portion minimum diameter is a cylindrical part, similar horn-like structure, and described side equates with the maximum gauge of conical portion that with the diameter of the cylindrical edge 7 of roller 2 described side equates with the minimum diameter of conical portion with the cylindrical part of roller 2;
