Specification for worm gearing - Metric units Ingestion-build-177197 more products can be offered1 Scope This Part of BS 721 specifies the requirements for worm gearing based on axial modules. Four classes of gear are specified, which are related to function and accuracy. This Part applies to worm gearing comprising cylindrical involute helicoid worms and wormwheels conjugate thereto. It does not apply to pairs of cylindrical gears connecting non parallel axes known as crossed helical gears. Appendix A gives some typical wheel rim sections
