A pair of enclosed spur gears have z1 =20, z2 =80, m = 3 mm and face width factor of ?d =1.0. The pinion rotates at n1 =970 rpm. The allowable contact stress of the pinion and gear are [?H1] = 700 MPa, [?H2] = 500 MPa, respectively. The load factor is K =1.5, zone factor is ZH =2.5, elastic coefficient is ZE =189.8 MPa1/2. Determine the power that can be transmitted by tooth surface contact strength analysis.
