Gear i.e. planetary gear, has cooler attached with shell part and arranged at gear, assembled pipe line fixed with cooler, returning part arranged in pipe line, and grooves opened in edge of shell part

摘要

The gear has a cooler attached with a shell part (1) and arranged at a gear. An assembled pipe line (3) is fixed with the cooler. A returning part i.e. tap (2), is arranged in the pipe line. The pipe line is shifted along a cooler area, formed in L-shape, U-shape or I-shape by steel casting. The returning part is interconnected with the shell part to limit bending of a pipe. Grooves are opened in an edge of the shell part. Radius of curvature of the returning part is greater than radius of the pipe.
