Abstract

A method of manufacturing gear teeth by additive manufacturing. Each tooth (20) is constructed from a predetermined number of layers (30, 31, 32) of material (e.g. steel) with each layer being formedby a predetermined number of rows (33-41) of material preferably applied by a welding head (13) or equivalent apparatus.

Description

technical field [0001] The present invention relates to the manufacture of gear teeth, and more particularly to the additive manufacture of gear teeth on cylindrical or conical base blanks. Background technique [0002] The term "additive manufacturing" is often used for 3D printing of 3D objects. 3D printing was initially used primarily to manufacture prototypes representing the geometry and even mechanical function of three-dimensional objects. However, 3D printed objects are often composed of materials that have different physical properties than replicated objects. Furthermore, the material structure is defined by the adhesion process of the powder layers (usually plastic powder). Plastic powders are similar to plastic pellets used in injection molding machines, but the pellets are greatly reduced in size, down to 50 μm or less in diameter. Adhesion of the layer of powder particles is achieved in the chemical process by a surrounding electrolyte with eg negative and p...
