A method for manufacturing a laminated rotor core includes a punching process for punching a strip-shaped material to make a core piece, a placing process, which is performed simultaneously with the punching process of the core piece, for placing the core piece in a die so that the core piece is placed on another core piece previously punched and placed in the die and a joining process for joining the core pieces.

Method for manufacturing laminated rotor core

A motor includes a core having a plurality of laminations, which are stacked together and an end-plate provided at an end surface of the core and supporting the core, wherein the end-plate is formed by pressing a hollow material in one direction thereof in order to plastically deform the hollow material in a plate-shape.

Motor

A webbed spiral bevel gear formed by cold forging includes: gear teeth formed at a peripheral surface of the gear basis to be integral therewith. Each gear tooth includes a tooth top land and a tooth bottom land both in a slanting and curved manner relative to a center axis of the gear basis. The webbed spiral bevel gear includes a web portion formed at radially outer end portions of the gear teeth to be integral therewith and closing the tooth bottom lands at the radially outer end portions of the gear teeth. The web portion is continuous with the radially outer end portions of the tooth top lands. A profile of the radially outer end portion of the tooth top land of each gear tooth has two edges extending at a slant from each other and expanding in a direction of the web portion.
