- Scope
- This guiding technical document is applicable to closed reduction gears and speed-up gears for industrial use, including spur gears, helical gears, herringbone gears or double helical gears and their combinations for single-stage or multi-stage transmissions. This guidance technical document provides a method for comparing and selecting gear transmission designs. It is not meant to guarantee the performance of the assembled gear train. The intent is to enable an experienced gear designer to select reasonable coefficient values based on knowledge of the performance of similar designs and an understanding of the effects of items such as lubrication, deformation, manufacturing tolerances, metallurgy, residual stresses, and system dynamics. Not intended for use by general engineering personnel. Maintaining an acceptable temperature in the oil tank of a closed wheel transmission is critical to the life of the gear transmission. Therefore, this 'guiding technical document not only considers the mechanical power of the closed gear transmission, but also considers the thermal power. The calculation methods and influencing factors in this guiding technical document are limited to single-stage and multi-stage designed closed transmissions, whose pitch line speed does not exceed 35 m/s, and the pinion speed does not exceed 4500 r/min. The tooth calculations included in this technical guidance document are limited to tooth root bending strength and tooth flank contact strength. This guiding technical document does not include the design and application of planetary transmission. A detailed analysis of efficiency is also outside the scope of this technical guidance document. Appendices A to F can be used to make a more detailed analysis of some calculation coefficients.
