• Mathematical models of the ZK-type worm and ZN-type worm wheel are developed based on their respective generating mechanisms. Kinematic errors (KEs) of the proposed worm gear drive under a non-ninety-degree crossing angle are calculated by applying the tooth contact analysis (TCA) method. Contact ratios (CR), instantaneous contact teeth (ICT) and average contact ratio (ACR) are investigated by applying the TCA method. It is found that the CR, ICT and ACR of the proposed worm gear drive are increased significantly when the crossing angle is chosen as 60 degrees. The effects of gear parameters on the ICT, CR, ACR and KEs under various crossing angle of the worm gear drive are demonstrated by an illustrative example.
