Problems solved by technology
[0002] At present; the belt conveyor roller, the steel pipe used for the pipe body is mainly a high-frequency welded pipe; the roller shaft is a machined shaft processed at both ends of the lathe; In the production of rollers, it is necessary to process step holes at both ends of the steel pipe, and then press the cast iron or plastic bearing seat into and use the stamped bearing seat, and weld it with the steel pipe. Because of machining errors and welding deformation, it is difficult to ensure the bearings at both ends. Concentricity, and increase the production cost. In addition, the traditional idler shaft is processed on a lathe, which leads to serious material waste and low production efficiency.

Embodiment Construction
[0014] The structure of the present invention is shown in Fig. 1, comprises the sealing cover (2) outer wall that is equipped with the sealing ring (4) sealing sleeve (5) of band redirecting protruding ring (11), and the outer wall of one end band step (9) is axially opened. There is a groove (10) inside the bearing housing (3) of the bearing (7), when the idler shaft (6) and the idler tube (8) are assembled, the bearing (7) with the idler shaft (6) will be installed Put it into the bearing seat (3), align the groove (10) on the outer wall of the bearing seat (3) with the welding seam of the idler tube (8) and install it, and then install the sealing ring (4) on the tapered surface Put the sealing sleeve (5) into the bearing housing (3), then install the sealing cover (2) on the idler shaft (6), and finally install the retaining ring (1) on the idler shaft (6).

The invention is concerned with the new belt conveying machine supporting roller, includes the sealed cap that is with direction-changing protruding ring, the stuffing box gland that the outer wall of it is with sealing ring, the bearing mounting that one end of it is with steps and the outer wall is with the groove opening along the axle direction, the bearing setting in the bearing mounting, the roller carrier shaft, and the support roller pipe, the characteristic is: the groove of the bearing mounting outer wall justifies with the welding line of the support roller pipe inner wall and fixes in the support roller pipe, the step surface of the bearing mounting presses with two end faces of the support roller pipe in order to locating the support roller pipe and the bearing mounting, the sealing ring of the stuffing box gland that is fix in the bearing mounting and press with the axle is reciprocity with the direction-changing protruding ring of the roller carrier shaft sealed cap in order to form seal.
Description
Technical field: [0001] The invention relates to a belt conveying mechanical idler, in particular to a belt conveying mechanical idler processed by high-frequency welded pipes. Background technique: [0002] At present; the belt conveyor roller, the steel pipe used for the pipe body is mainly a high-frequency welded pipe; the roller shaft is a machined shaft processed at both ends of the lathe; In the production of rollers, it is necessary to process step holes at both ends of the steel pipe, and then press the cast iron or plastic bearing seat into and use the stamped bearing seat, and weld it with the steel pipe. Because of machining errors and welding deformation, it is difficult to ensure the bearings at both ends. concentricity, and increase the production cost. In addition, the traditional idler shaft is processed on a lathe, which leads to serious material waste and low production efficiency. Invention content: [0003] The object of the present invention is to pro...
