Question

A 35 kW motor running at 1200 rpm drives a compressor at 780 rpm. The arrangement is made through a 90° bevel gearing arrangement. The pressure angle of teeth is 14.5°. The allowable static stress for both pinion and gear are 85 MPa. Determine the number of teeth on the gear, face width, addendum, dedendum, outside diameter and slant height, thickness of tooth. Also check your design from the standpoint of wear. Take surface endurance limit as 690 MPa and modulus of elasticity as 89 kN/mm2.

Problem 2: A 35 kW motor running at 1200 rpm drives a compressor at 780 rpm. The arrangement is made
through a 90° bevel gearing arrangement. The pressure angle of teeth is 14.5°. The allowable static stress for
both pinion and gear are 85 MPa. Determine the number of teeth on the gear, face width, addendum, dedendum,
outside diameter and slant height, thickness of tooth. Also check your design from the standpoint of wear. Take
surface endurance limit as 690 MPa and modulus of elasticity as 89 kN/mm?.
