Worm Gear Load Analysis

In a worm gear, the actual work is done through $W_{tW}$ (input) and $W_{tG}$ (output). They are related to each other as

$$W_{tW}=W_{tG}\frac{\cos {\varphi }_n\sin \lambda +\mu \cos \lambda }{\cos {\varphi }_n\cos \lambda -\mu \sin \lambda }=W_{tG}\frac{\cos {\varphi }_n\tan \lambda +\mu }{\cos {\varphi }_n-\mu \tan \lambda }$$
