GB/T 39545.1-2022 is the Chinese standard "Design and selection of components for enclosed gear drives—Part 1: Common components".

Its scope clause reads: This document specifies terms, definitions and symbols for the design and selection of general components for closed gear transmissions, design calculation conditions, shafts, keys and keyed interference fit connections, bearings, threaded fasteners, housings, overrunning clutches, shrink discs, couplings, lubrication, motors and other components Design and selection.

This document applies to the general component design and choose. The formulas and values in this document are applicable to the design and selection of general components for conventional industrial enclosed gear transmissions.

When higher settings are required When measuring accuracy, design deviations can be corrected by combining experience, experiments and more professional analysis.

This document is for experienced designers, optional Take appropriate values and know the effects of the following. lubrication, deformation, manufacturing errors, material heat treatment, residual stress and system vibration, etc. There are special standards for the design of gears, worms and other components, and this document will not be repeated.

This document does not apply when transmissions are subjected to vibrational conditions that may lead to unpredictable fatigue failures.
