High-contact ratio spur gears with conformal contact and reduced sliding
Results in Engineering, 2022 The high-contact ratio (HCR) spur gear is a possible choice for a quiet and smooth gearing system. However, HCR spur gear of the involute type has several constraints, such as high sliding contact under large loads and interference problems in high speed
