Abstract
A speed-adjustable roller relates to the technical field of rollers. The speed-adjustable roller comprises a main shaft sleeved with a sleeve, and is characterized in that the two ends of the main shaft are fixedly sleeved with a ring sleeve respectively, round holes in the middle of the ring sleeves are stepped round holes, the main shaft is inserted into small holes in the stepped round holes, the sleeve is sleeved with a large hole, the side faces of the ring sleeves are provided with holes, fastening screws are arranged in the holes, and the fastening screws penetrate through the holes to be abutted against the sleeve. The speed-adjustable roller is simple in structure, reasonable in design, simple and practical and has a good effect, and the rotating speed of the whole roller is controlled through the rotating flexibility of the sleeve determined by the contact extrusion force between the fastening screws and the sleeve.
Description
Technical field:
The utility model relates to cylinder technical field, is specifically related to a kind of adjustable speed cylinder.
Background technology:
Existing roller frame is mostly on main shaft the speed rolling that cover has sleeve, sleeve depending on to transmit thing, and speed is uncontrolled, cannot meet present diversified demand.
Utility model content:
Technical problem to be solved in the utility model is to overcome the defect of prior art, provides a kind of simple in structure, the convenient cylinder regulating.
Technical problem to be solved in the utility model realizes by the following technical solutions.
A kind of adjustable speed cylinder, comprise main shaft, on main shaft, cover has sleeve, it is characterized in that: described main shaft two ends are fixed with annulus cover, the circular hole in the middle of annulus cover is ladder circular hole, in the aperture in ladder circular hole, is inserted with main shaft, macropore entangles sleeve, described annulus cover side is provided with hole, is provided with tightening screw in hole, and tightening screw withstands on sleeve through hole.
Macropore corner in described ladder circular hole is inlaid with ball.
Described annulus cover side is provided with 3-4 hole, and is evenly distributed on annulus cover side.
Described annulus cover side is preferably provided with 3 holes.
The utility model is simple in structure, reasonable in design, and the contact squeeze dynamics size of tightening screw and sleeve determines the flexibility ratio that sleeve rotates, thereby controls the velocity of rotation of whole cylinder, and simple and practical, effect is remarkable.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Wherein: 1: main shaft; 2: sleeve; 3: annulus cover; 4: hole; 5: tightening screw; 6: ball.
