摘要： A plurality of conductor bars are positioned within slots of a laminated electric steel disc stack, and the ends of the conductor bars are brazed to end rings to manufacture a rotor. The method includes inserting the conductor bars into the slots of the disc stack, providing the end rings with slots for receiving the ends of the conductor bars; positioning spacers of braze material adjacent each end of each of the conductor bars to create a gap between the end rings and the steel disc stack; and applying heat to melt the braze material of the spacers whereby braze material is furnished by the spacers of braze material to braze the first and second ends of the conductor bars to the first and second end rings. Channels are provided in the face of the end rings facing the steel disc stack to drain away excess braze material.

摘要： A method of manufacturing a rotor assembly includes positioning a laminated stack of electric steel sheets with a plurality of conductor bars positioned within longitudinal grooves defined by the laminated stack in a mold, and casting an end ring in place over ends of the conductor bars. In order to cast the end ring in place, heated liquid aluminum is injected into a cavity defining the end ring, and circulated within the cavity and around the ends of the conductor bars to create relative movement between the liquid aluminum and the ends of the conductor bars to heat the conductor bars and flush oxides away from an outer surface of the conductor bars.

摘要： In a preferred embodiment, a compound aluminium alloy engine block casting comprises at least a piston-travel region of a cylinder wall section formed of a first alloy, preferably hypereutectic aluminum-silicon alloy, and a remainder including a crankcase section and a water jacket wall formed of a distinct second alloy, preferably hypoeutectic aluminum-silicon alloy. The engine block casting is made by a lost foam process that employs an expendable pattern formed of expanded polystyrene or the like. The pattern comprises a first runner system for casting the first alloy to decompose and replace a portion of the pattern corresponding to the piston-travel region of the casting, and a second runner system for casting the second alloy to decompose and replace the remainder of the pattern. The first alloy and the second alloy are independently but concurrently cast into a singular mold, such that the entire pattern is duplicated, whereupon the alloys merge and fuse to form an integral casting. The preferred product engine block casting advantageously combines the high wear resistance of the hypereutectic aluminum alloy in the cylinder wall section and the reduced porosity and improved machinability of the hypoeutectic alloy throughout the balance of the casting.

摘要： A "lost foam" method of making a casting having a preform embedded at a selective location therein including the steps of: engulfing a porous preform in a fugitive pattern; embedding the pattern in a loose sand mold in a vessel; pouring molten metal into the mold cavity via a sprue and runner system formed in the sand bed so as to destroy the pattern and fill the mold cavity with metal; pressurizing the vessel to force molten metal from the cavity into the porous preform; replacing metal lost from the cavity with make-up metal from the sprue and runner system; allowing the casting to solidify; and removing the casting from the sand bed.
