Abstract
The utility model relates to an unpowered roller preventing a central shaft from rotating. The utility model is provided with a roller body, a central shaft, a bearing and a sealing cover type bearing seat. The radial section of the central shaft is a polygon, and a shaft sleeve is installed in the inner bore of the bearing. The inner bore of the shaft sleeve is a polygonal axial bore matched with the polygonal central shaft. The utility model has the advantage that the two ends of the central shaft of the roller are inserted in the slotted holes in a machine frame and can not rotate, so that the steady and reliable operation of the roller can be ensured.
Description
Technical field
The utility model relates to a kind of roller of unpowered roller conveyor.
Background technology
The roller of unpowered roller conveyor, generally by roller body, column type center shaft and end mounted bearing thereof, be fixedly connected with roller body and form as the bearing seat of roller body two ends capping, cylindrical center axle two ends are passed capping formula bearing seat and are plugged in the axis hole of frame.During work, roller body rotates around center shaft, but center shaft also can rotate in the frame axis hole sometimes, thereby causes the roller running steady inadequately.
Summary of the invention
The technical matters that the utility model quasi-solution is determined is can prevent that for unpowered roller conveyor provides a kind of center shaft from rotating, the unpowered roller of the steady failure-free of running.
Technical solution of the present utility model is: it has roller body, center shaft, bearing and capping formula bearing seat, the radial section of its center shaft is a polygon, in the endoporus of bearing axle sleeve is installed, the polygon axial hole of the endoporus of axle sleeve for matching with the polygon center shaft.
The beneficial effects of the utility model are: roller center axle two ends are plugged in the slotted eye of frame and can rotate, thereby guarantee that the roller running is steadily reliable.
Description of drawings
Accompanying drawing is a three-dimensional decomposition texture scheme drawing of the present utility model.
The specific embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing.
Present embodiment center shaft 2 axis body radial sections are regular hexagon, and the place is provided with spacing protruding 7 respectively near the axle two ends.Be provided with the axle sleeve 6 of the hexagon axial center hole that matches with hexagon center shaft 2, press-fit in the endoporus of bearing 4, bearing 4 then is installed in the axial center hole of capping formula bearing seat 5.The above-mentioned capping formula bearing seat 5 that installs bearing 4 and axle sleeve 6 is socketed on roller body 1 one ports, insert center shaft 2 from roller body 1 another port, and this port again socket install the capping formula bearing seat 5 of bearing 4 and axle sleeve 6, the capping formula bearing seat 5 of stationary roll cylindrical shell 1 two-port then.Center shaft 2 two ends that pass roller body 1 two-port are plugged in the slotted eye of frame.In order to prevent center shaft 2 end float misalignments, center shaft 2 wherein is equipped with spring 3 between spacing protruding 7 and the bearing 4 of an end.
