Abstract

The invention provides an unpowered roller structure relating to the technical field of unpowered rollers. The unpowered roller structure has small processing difficulty and comprises a roller, a roller shaft and frames on two ends, wherein the roller shaft penetrates through the center of the roller, and the roller shaft is supported on the frames on two ends. The unpowered roller structure is characterized in that two ends of the roller shaft expose out of the roller, two ends of the roller shaft are provided with screw threads, the frames on two ends are respectively sheathed on two ends of the roller shaft, nuts on the outer sides of the frames on two ends are respectively in threaded connection with the screw threads on two ends of the roller shaft, and the nut tightly presses the outer sides of the frames on two ends.

Description

Unpowered roller frame

Technical field

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

Background technique

Existing unpowered cylinder mounting structure 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, and the contraposition complexity, difficulty of processing is big.

Summary of the invention

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

Unpowered roller frame, its technological scheme is such: it comprises the framework at cylinder, drum shaft, two ends, the center of described cylinder is penetrated with described drum shaft, described drum shaft is supported on the framework at described two ends, it is characterized in that: described cylinder is exposed at the two ends of described drum shaft, the two ends of described drum shaft have screw thread, the framework at described two ends is set with the two ends in described drum shaft, be threaded the respectively screw thread at two ends of described drum shaft of the framework nut outside at described two ends, and described nut compresses the framework outside at described two ends.

After adopting said structure of the present invention, the two ends of drum shaft directly connect the framework at two ends, carry out fasteningly afterwards, and it can guarantee that it is installed on the same axis, and it need not extra contraposition, and difficulty of processing is little.

Description of drawings

Fig. 1 is a structural representation of the present invention.

Embodiment

See Fig. 1, it comprises framework 2, the drum shaft 3 at cylinder 1, two ends, the center of cylinder 1 is penetrated with drum shaft 3, drum shaft 1 is exposed at the two ends of central shaft 3, the two ends of drum shaft 3 have screw thread, the framework 2 at two ends is set with in the two ends of drum shaft 3, be threaded the respectively screw thread at two ends of drum shaft 3 of framework 2 nut outside 4 at two ends, and nut 4 compresses framework 2 outsides at two ends.

Claims

1. unpowered roller frame, it comprises the framework at cylinder, drum shaft, two ends, the center of described cylinder is penetrated with described drum shaft, described drum shaft is supported on the framework at described two ends, it is characterized in that: described cylinder is exposed at the two ends of described drum shaft, the two ends of described drum shaft have screw thread, the framework at described two ends is set with the two ends in described drum shaft, be threaded the respectively screw thread at two ends of described drum shaft of the framework nut outside at described two ends, and described nut compresses the framework outside at described two ends.
