5. Gearbox Sketch Layout

The purpose is to develop the design scheme necessary for the performance of check calculations of shafts, key joints, bearings .

Gearbox general view drawing (sketch layout) sets the position of gearbox pair wheels relative to supports (bearings). The drawing allows you to determine the location of the points of application of forces in the engagement of the reduction gear, open gears, couplings and reactions of supports. The drawing is made in accordance with the requirements of the ESKD on millimeter paper of at least A3 format with a pencil.,
