Abstract

The utility model provides a motorless roller structure, which relates to the technical field of motorless rollers, and is simple for contraposition and is easy to process, and comprises a roller, a roller shaft and frameworks on two ends, wherein the roller shaft passes through the center of the roller, and the motorless roller structure is characterized in that: two ends of the roller shaft extend out of the roller, one end of the roller shaft is provided with threads, the other end of the roller shaft is a semilunar structure, the framework on one end is provided with a circular hole, the framework on the other end is provided with a semilunar hole, one end of the roller shaft passes through the circular hole of the framework on one end, a nut is connected with one end of the roller shaft through the threads and compresses the outer side of the framework on one end, the other end of the roller shaft passes through the semilunar hole of the framework on the other end, and a pin shaft passes through a locking hole of an arc surface on the other end of the roller shaft.

Description

A kind of motorless roller frame

Technical field

The utility model relates to the technical field of unpowered cylinder, is specially a kind of 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 utility model provides a kind of motorless roller frame, and its contraposition is simple, difficulty of processing is little.

A kind of 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 utility model, 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.
