HOUSING OR REDUCTION GEAR FOR PLANETARY REDUCTION GEAR, AS WELL AS METHOD OF ITS MANUFACTURE Russian patent published in 2014 - IPC F16H57/08 F16H57/23 B23K26/20 

FIELD: machine building.

SUBSTANCE: invention relates to a housing of a reduction gear, and namely to a housing of a planetary reduction gear. Housing (1) of the planetary reduction gear has hollow cylindrical body (2) with internal gear rim (3), which is connected on end surfaces to supporting flange (4, 5). Body (2) of the housing and at least one supporting flange (4, 5) are provided with axial overlap on the end surface for formation of overlap area (A, B). In overlap area (A, B), body (2) of the housing and at least one supporting flange (4, 5) have press fit (6). In overlap area (A, B), as materials for body (2) of the housing and for supporting flange (4, 5) a provision is made for one material permeable for laser light and one material non-permeable for laser light so that the housing body and the supporting flange are welded to each other by welding with penetrating beam of laser, which is directed inside housing (1) of the reduction gear by laser emission in the overlap area. The invention describes a manufacturing method of the reduction gear housing, as well as the planetary reduction gear with such a housing.

EFFECT: invention is aimed at creation of a compact structure with light weight.
