Description

Novel ceramic roller

Technical Field

The utility model discloses a novel ceramic roller belongs to the mechanical device field.

Background

The silicon steel sheet is a soft magnetic material, is an alloy material with the largest consumption in magnetic materials, is mainly used for manufacturing transformers, motor cores and other magnetic conductive components in the electrical industry, and is an essential important material for the industries of electric power engineering, motor manufacturing, household appliances, radio technology, telecommunication instruments and the like. In the machining process, on one hand, too many form and position tolerances exist between the pin hole and the screw hole of the flange, on the other hand, the requirement on the straightness of the screw holes at two ends on the machining roller core is extremely high, and the machining equipment is limited, and the ceramic sleeve cannot be stressed during assembly and the like, so that the state that one end of the flange is assembled smoothly and the other end of the flange cannot be assembled is often met, the ceramic roller with the novel structure is developed, and the problem that the positioning screw hole cannot be assembled on the flange is solved.

SUMMERY OF THE UTILITY MODEL

To the problem that exists among the above-mentioned prior art, the utility model provides a novel ceramic roller, the technical scheme who adopts is:

the novel ceramic roller comprises a roller core, a flange, an outer ring, a positioning pin, a screw and a ceramic sleeve, and is characterized in that two ends of the roller core are respectively provided with a second screw hole, the outer ring is provided with a first screw hole, two ends of the ceramic sleeve are respectively provided with a positioning hole, and the flange is provided with a through hole; the roller core is sleeved with the ceramic sleeve, and the two ends of the ceramic sleeve are respectively connected with the flange and the outer ring in sequence; the flange is fixedly connected with the outer ring; the positioning pins respectively penetrate through holes on the flanges at the two ends to be connected with the positioning holes; and the screws respectively penetrate through the first screw holes and are connected with the second screw holes in a positioning manner.

Preferably, the flange is connected with the outer ring through spot welding.

As a preferable technical scheme, the screw is a socket head cap end fastening screw.

As a preferable technical scheme, a spring washer is arranged between a nut and a flange of the positioning pin.

The utility model discloses a ceramic roller simple structure, easily processing, maneuverability is strong, greatly reduced because silk hole adds the difficult problem of easy existence deviation with the roller core man-hour, and the processing cost is lower, and is efficient during the change, has durable's advantage.

1. The roller comprises a roller core, 2, a flange, 3, an outer ring, 4, a positioning pin, 5, a screw, 6, a ceramic sleeve, 7, a through hole, 8, a positioning hole, 9, a first screw hole, 10 and a second screw hole.

Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the following description is given with reference to the accompanying drawings of the present invention for clear and complete description of the technical solution of the present invention.

The utility model provides a novel ceramic roller, which comprises a roller core 1, a flange 2, an outer ring 3, a positioning pin 4, a screw 5 and a ceramic sleeve 6. Two ends of the roller core 1 are respectively provided with a screw hole II 10, the outer ring 3 is provided with a screw hole I9, two ends of the ceramic sleeve 6 are respectively provided with a positioning hole 8, and the flange 2 is provided with a through hole 7; the ceramic sleeve 6 is sleeved outside the roller core 1, and two ends of the ceramic sleeve 6 are respectively connected with the flange 2 and the outer ring 3 in sequence; the flange 2 is fixedly connected with the outer ring 3; the positioning pins 4 respectively penetrate through holes 7 on the flanges 2 at the two ends to be connected with the positioning holes 8, so that the flanges 2 are tightly connected with the ceramic sleeves 6; and the inner hexagonal cone end set screw penetrates through the outer ring screw hole I9 to be connected with the roller core screw hole II 10 in a positioning manner, so that the outer ring 3 is fixedly connected with the ceramic roller core 1. The flange 2 and the outer ring 3 are connected into a whole through spot welding. Be equipped with spring washer between locating pin 4 and the flange 2, this spring washer can increase the pretightning force, prevents effectively that the nut vibrations from becoming flexible. The ceramic roller transfers the original inner hexagonal cone end fastening screw hole to the outer sleeve, a ring is added outside the circular flange, the hole is drilled on the ring, the ceramic sleeve is fixed by the flanges at two ends (the cone hole is drilled on the roller core in advance), the outer ring is positioned by the hole of the roller core, the outer ring is welded on the flange in a spot welding mode, the inner hexagonal cone end fastening screw is fastened at last, and the effective fixation of the ceramic sleeve is finally realized.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is familiar with the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered in the protection scope of the present invention.
