Abstract

The invention provides a powerless roller structure, which relates to the technical field of powerless roller and has the advantages of simple alignment and small processing difficulty. The powerless roller structure comprises a roller, a roller shaft penetrating through the center of the roller, and frames at two ends, wherein the roller extends out of the two ends of the roller shaft, one end of the roller shaft is provided with a thread while the other end of the roller shaft is structured as a half-moon shape, the frame at one end is provided with a round hole while the frame at the other end is provided with a half-moon shaped hole, one end of the roller shaft penetrates through the round hole of the frame at one end, a nut is in threaded connection with the thread at one end of the roller shaft and tightly presses the outer side of the frame at one end, the other end of the roller shaft penetrates through the half-moon shaped hole of the frame at the other end, and a pin shaft penetrates through a locking hole with arc face at the other end of the roller shaft.

Description

Motorless roller frame

Technical field

The present invention relates to the technical field of unpowered cylinder, be specially motorless roller frame.

Background technique

Existing motorless cylinder, it is at the two ends of drum shaft thread mill drilling, by screw framework is fastened on the two ends of drum shaft, because thread mill drilling need be distinguished in its two ends, need its processing on same axis, the contraposition complexity, difficulty of processing is big.

Summary of the invention

At the problems referred to above, the invention provides motorless roller frame, its contraposition is simple, difficulty of processing is little.

Motorless roller frame, its technological scheme is such: it comprises cylinder, drum shaft, the framework at two ends, the center of described cylinder is penetrated with described drum shaft, it is characterized in that: described cylinder is exposed at the two ends of described drum shaft, one end of described drum shaft has screw thread, the other end of described drum shaft is the semilune structure, the described framework of one end has circular hole, the described framework of the other end has half-lune holes, one end of described drum shaft passes the circular hole of the described framework of an end, nut thread connects the threaded one end of described drum shaft, and compress the outside of the described framework of an end, the other end of described drum shaft runs through the half-lune holes of the described framework of the other end, and bearing pin passes the locking hole of arc surface of the other end of drum shaft.

After adopting said structure of the present invention, an end of drum shaft is to after being positioned at circular hole, adjusts the drum shaft position and makes the other end of drum shaft to being positioned at the half-lune holes of framework, and its contraposition is simple, difficulty of processing is little.
