Abstract

The utility model discloses an equicohesive rotor for a ball mill. The rotor comprises two hollow shafts, an end cover, a gear, a cylinder body and a corrugated lining plate, wherein the hollow shafts and the end cover are provided with hollow shafts, shaft necks, end covers and multi-head helix guiding edges; the outer surface of the hollow shafts are cylindrical faces, the raised cylindrical faces are the shaft necks, inner surface of the hollow shafts are truncated conical faces; the multi-head helix guiding edges are arranged on the inner walls of the hollow shaft; inner and outer surfaces of the end covers are truncated conical faces, cone angles of the outer surfaces are less than those of the inner surfaces; the hollow shafts and the end covers are in large-circular-angle transition connection to form an integrated structure; the cylinder body comprises a first cylinder and a second cylinder, rib plates with variable cross sections are uniformly distributed on outer cylindrical surfaces of the first and second cylinders; the corrugated lining plate is provided with a curve lifting edge, a plurality of countersunk screw holes and a lightening groove; the first cylinder and the second cylinder are connected by a flange plate through a bolt group; the corrugated lining plate is alternately arranged inside the cylinder body through wedge-caulking and the bolt group. According to the equicohesive rotor, the rib plates with variable cross sections are uniformly distributed on the outer cylindrical surfaces of the cylinder body, so that the section of the rotor has the same strength, the conflict between the dead weight of the rotor and the strength and rigidity of the rotor can be solved, and the dead weight of the rotor can be reduced to a certain extent.

Description

A kind of equal strength revolving body of ball mill

Technical field

The utility model relates to a kind of revolving body of ball mill, particularly a kind of equal strength revolving body of ball mill.

Background technology

The specification of ball mill constantly increases, and revolving body is the critical component of ball mill, and its design is had higher requirement, and the strength and stiffness of existing ball mill revolving body and the contradiction of its deadweight are more outstanding.

Utility model content

The purpose of this utility model is to provide a kind of equal strength revolving body of ball mill.

The utility model is by two quill shafts and end cap, gear, cylindrical shell and corrugated liner plate form, quill shaft and end cap have quill shaft, axle journal, end cap and multi-head spiral are led rib, the outer surface of quill shaft is the face of cylinder, the face of cylinder of its protrusions is axle journal, quill shaft inner surface is frusto-conical surface, quill shaft inwall has multi-head spiral and leads rib, end cap surfaces externally and internally is frusto-conical surface, outer surface cone angle is less than inner surface cone angle, the strength structure that quill shaft and end cap link into an integrated entity with arc transition, cylindrical shell is comprised of the first cylinder and the second cylinder that are evenly equipped with variable cross-section gusset on external cylindrical surface, on corrugated liner plate, there is curve lifting rib, a plurality of dormant bolts hole and lightening grooves, the first cylinder is connected by bolt group by ring flange with the second cylinder, one of them quill shaft and end cap are connected with the ring flange of the first cylinder by the bolt group through gear hub, another quill shaft and end cap are connected by bolt group by ring flange with the second cylinder, corrugated liner plate is staggered installation of in inner barrel by wedging and bolt group.

The beneficial effects of the utility model: solved the deadweight of revolving body and the contradiction between its strength and stiffness, reduced to a certain extent the deadweight of revolving body.
