A three-dimensional inclined toothed roller crusher, comprising a casing, a plurality of power devices mounted on the casing, a base located at one end of the casing away from the power device, a plurality of groups of toothed rollers, a plurality of toothed rollers installed on each toothed roller A number of crushing teeth on the upper part, and a number of blocking bodies installed on the inner wall of the casing; the toothed rollers correspond to the power device one-to-one respectively; each of the toothed rollers is respectively connected to the base and the corresponding power device; the teeth The rollers are evenly distributed in the casing around the central axis of the casing and are inclined from the base toward the power unit. The three-dimensional inclined toothed roller crusher of the present invention achieves the characteristics of large crushing ratio, high screening efficiency, large processing capacity and three-dimensional crushing through the cooperation of the casing and the toothed rollers through several toothed rollers arranged obliquely in space, thereby effectively improving the Crushing efficiency and crushing quality.

The invention discloses a method for preparing an aluminum silicon carbide water-cooled gear plate. A high-pressure forging method is adopted to soak a porous silicon carbide prefabricated body in the molten metal of aluminum alloy under high temperature and high pressure, control the impregnation pressure and pressure holding time, and cool the After demolding, an aluminum-silicon carbide composite body with a thickness of 3 to 7 mm is obtained; aluminum alloys containing magnesium are selected, the temperature of aluminum melting and mold temperature are controlled, and aluminum alloy water-cooled tooth plates are prepared by high-pressure forging; the prepared aluminum alloys are welded The silicon carbide composite body is connected with the prepared aluminum alloy water-cooled tooth plate to form the aluminum silicon carbide water-cooled tooth plate. The present invention connects the tooth column and the aluminum silicon carbide composite plate base by welding, which solves the problem of missing teeth and broken teeth in the traditional process. The welding strength is high and the welding porosity is low, reflecting the superiority of the process of the present invention.

The invention relates to a hardened-tooth-surface gear, which comprises a gear main body. A fusion covering layer is arranged on the surface of the gear main body. The fusion covering layer comprises a bonding layer, a transition layer, a working layer and a processing layer, wherein the bonding layer is arranged on the external surface of the gear main body; the transition layer is arranged on the top surface of the bonding layer; the working layer is arranged on the top surface of the transition layer; and the processing layer is arranged on the top surface of the working layer. The invention additionally discloses a hardened-tooth-surface gear repair technology, which comprises a pretreatment step for pretreating the hardened-tooth-surface gear to enable the hardened-tooth-surface gear to satisfy repair requirements; a repair step for forming the fusion covering layer on the surface of the hardened-tooth-surface gear; and a processing step for processing the repaired hardened-tooth-surface gear to enable the hardened-tooth-surface gear to satisfy a repair standard. The hardened-tooth-surface gear repair technology provided by the invention can be used for repairing surface wear, cracks and cutting root broken teeth of the hardened-tooth-surface gear to guarantee full engagement of gear teeth, the noise produced during gear teeth engagement is reduced, the gear teeth are prevented from being broken, the rejection rate of the hardened-tooth-surface gear is reduced, the production cost is reduced, the resource waste is reduced, and the economic and social benefits of enterprises are improved.
