20210324916 · 2021-10-21 ·

An upper case manufacturing method using an axial draw mold, in molding of an upper case made of a synthetic resin and including an inclined cylindrical portion. A fixed mold is provided with a first half body, and a movable mold is provided with a second half body. The first half body and the second half body abut against each other in an inclined plane. The first half body has a first flat surface at both ends on the inner diameter side of the inclined cylindrical portion in the inclined plane, and the second half body has a second flat surface at both ends on the inner diameter side of the inclined cylindrical portion in the inclined plane. The first flat surface and the second flat surface are flat surfaces that prevent the occurrence of undercutting when the upper case is removed from an injection molding mold.

ADDITIVELY MANUFACTURED JOURNAL BEARING FOR A WIND TURBINE GEARBOX

A method for manufacturing a gear assembly of a gearbox in a wind turbine includes providing a pin shaft of the gear assembly. The method also includes depositing material onto an exterior surface of the pin shaft of the gear assembly via an additive manufacturing process driven by a computer numerical control (CNC) device to form a bearing that circumferentially surrounds and adheres to the pin shaft. Further, the method includes providing a gear circumferentially around the bearing to form the gear assembly.

ADDITIVELY MANUFACTURING FLUORINE-CONTAINING POLYMERS

A system and method of additively manufacturing a part including fluorine-containing polymers and an additive. The additive may include stainless steel, bronze, molybdenum disulfide, polyimide, or any other suitable additive. The method includes depositing fluorine-containing polymer additive manufacturing material onto a build platform, selectively cross-linking portions of the deposited additive manufacturing material, and curing the selectively cross-linked portions such that at least one characteristic of the part is improved via the additive.
