Although the inherent backlash problem of gear systems has been solved by means of utilizing two pinions independently preloaded, the time-varying mesh stiffness causes periodic position differences between the motor encoder and table position, which is known as transmission error, and may lead to vibrations and dynamic load. Few experimental works have analyzed such transmission error, but there are no theoretical approaches in the scientific literature. Therefore, this work aims to first extend previous analytical and approximate equations for mesh stiffness of gearing to rack and pinion systems and validate them with finite element methods. Finally, the effect of geometry variations, such as pressure angle and tooth thickness tolerance, on transmission error is discussed. 2261-236X https://katalogoa.mondragon.edu/janium-bin/janium_login_opac.pl?find&ficha_no=176340 https://hdl.handle.net/20.500.11984/6312 ODS 9 Industria, innovación e infraestructura ODS 12 Producción y consumo responsables Theoretical analysis of transmission error in rack and pinion systems
