Description

Direct-drive roller and roller conveyor Technical Field The application relates to the technical field of mechanical transmission, in particular to a direct-drive roller and a roller type conveying device. Background The roller type conveying device is widely applied to the fields of industrial production, storage and distribution, port logistics and the like, has the characteristics of rapidness, high efficiency, reliability and the like, and saves a large amount of manpower and material resources. The roller conveyor is generally formed by arranging a plurality of direct-drive rollers along a certain direction, wherein each direct-drive roller comprises a motor, a roller wheel and a coupling piece arranged between the motor and the roller wheel. In the prior art, the coupling piece generally comprises two clamping plates which are butted in the axial direction, wherein one clamping plate is arranged in the motor, the other clamping plate is arranged outside the motor, a rubber ring is arranged between the two clamping plates, and the rubber ring is extruded in the axial direction to deform in the butting process of the two clamping plates, so that the radial dimension of the rubber ring is increased to be in close contact with the inner wall of the roller. When the motor rotates, the roller can rotate along with the rubber ring through friction between the rubber ring and the roller. When the roller type conveying device works, the direct-drive rollers of the roller type conveying device simultaneously rotate to drive the objects to be conveyed to move along the arrangement direction of the direct-drive rollers. The coupling piece of the direct drive roller with the structure is composed of a plurality of elements, so that the coupling piece is complex in structure, difficult to assemble, limited in power transmission capacity and needs to be further improved.
