Abstract
The utility model discloses a roller supporting device special for a belt conveyor which resolves the technical problems that a rubber tape is short in service life and prone to deflection. The roller supporting device comprises a roller body, wherein a shaft is arranged in an inner cavity of the roller body, and a bearing cavity matched with the shaft is arranged inside one end of the roller body along the center line of the roller body. A seal ring matched with the shaft, a bearing, an inner seal ring, an outer seal ring, a seal disc and an inner retainer ring are arranged inside the bearing cavity in sequence. An outer retainer ring is connected with the tail end of the outer seal ring and the tail end of the inner retainer ring, a check ring is arranged on the shaft through a clamping groove, the outer retainer ring is connected with the check ring through a baffle, and a plurality of rubber tape positioning grooves are uniformly arranged in the outer surface of the roller body along the radial direction of the roller body.
Description
Technical field
The utility model relates to conveying machinery, is specifically related to a kind of roller-supporting device of belt conveying.
Background technology
The advantages such as it is simple in structure that band conveyor has general belt conveyor, reliable, easy to maintenance, and have the characteristics such as high spud angle conveying, compact conformation, occupation of land are few, thereby be the ideal equipment of high spud angle convey materials.Can be used for conveying powdered and lumpy bulk material, have wide range of applications.The band conveyor main resistance be carrying roller to the resistance of adhesive tape, in the prior art, the contact surface of carrier roller adhesive tape is larger, thereby friction is large between adhesive tape and the carrying roller, the long-time use easily produces wearing and tearing, belt work life is short; Infinite place device between adhesive tape and the carrying roller easily produces deviation phenomenon simultaneously.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of support roller device that is exclusively used in band conveyor, can Effective Raise belt work life, the simultaneously difficult deviation phenomenon that produces.
For achieving the above object, the support roller device that is exclusively used in band conveyor of the present utility model, comprise roll body, described roll body inner chamber is provided with axle, roll body one end is built-in with the bearing bore that mates with axle along its line of centers, be disposed with seal ring, bearing, inner seal ring, exterior seal ring, seal disc and inner shield ring with the axle coupling in the bearing bore, the end of exterior seal ring and inner shield ring is connected with outer back-up ring, be provided with back-up ring by draw-in groove on the axle, outer back-up ring is connected with back-up ring through baffle plate, and described roll body outside face radially evenly is provided with a plurality of adhesive tape positioning grooves along it.
After having adopted technique scheme, because the roll body outside face radially evenly is provided with a plurality of adhesive tape positioning grooves along it, thereby so that during band conveyor work, roll body and tape contact face amass and reduce, and have reduced friction, can prolong belt work life.During band conveyor work, bearing a heavy burden is absorbed in the adhesive tape positioning groove adhesive tape slight deformation, crushed element, and adhesive tape can not move axially along roll body, thereby is difficult for producing sideslip.
Description of drawings
Fig. 1 is the schematic diagram that is exclusively used in the support roller device of band conveyor of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, the support roller device that is exclusively used in band conveyor of the present utility model, comprise roll body 1, described roll body 1 inner chamber is provided with axle 2, roll body 1 one ends are built-in with the bearing bore 12 that mates with axle 2 along its line of centers, be disposed with seal ring 3, bearing 4, inner seal ring 5, exterior seal ring 7, seal disc 6 and inner shield ring 8 with axle 2 couplings in the bearing bore 12.Inner seal ring 5, exterior seal ring 7 form a seal group, and sealing group and seal ring 3 place respectively the two ends of bearing 4, can guarantee the dustproof and lubricated of bearing 4.
The end of exterior seal ring 7 and inner shield ring 8 is connected with outer back-up ring 9, is provided with back-up ring 11 by draw-in groove on the axle 2, and outer back-up ring 9 is connected with back-up ring 11 through baffle plate 10.Inner shield ring 8 adopts the "the" shape structure, possesses certain elastic potential energy, can further play positioning action to each parts in the bearing bore 12.
Described roll body 1 outside face radially evenly is provided with a plurality of adhesive tape positioning grooves 13 along it, thereby so that band conveyor when work, roll body 1 reduces with tape contact face is long-pending, has reduced friction, can prolong belt work life.During band conveyor work, bearing a heavy burden is absorbed in the adhesive tape positioning groove 13 adhesive tape slight deformation, crushed element, and adhesive tape can not move axially along roll body 1, thereby is difficult for producing sideslip.
