Question

3 Required information Problem 14.022 -DEPENDENT MULTI-PART PROBLEM- ASSIGN ALL PARTS art 2 of 2 A spur gearset has 17 teeth on the pinion and 51 teeth on the gear. The pressure angle is 20° and the overload factor 1. The diametral pitch is 6 teeth/in and the face width is 2 in. Tihe pinion speed is 1050 rev/min and its cycle life is to be revolutions at a reliability R 0.99. The quality number is 5. The material is a through-hardened steel, grade 1, with Bri hardnesses of 232 core and case of both gears. For a design factor of 2.3, rate the gearset for these conditions using AGMA method. Problem 14.022.c-Contact Stress Factors and Power Rating Determine the value of the transmitted load, w, the stress-cycle factor for pitting resistance (pinion), the geometry factor for resistance, the allowable contact stress, and the achievable power based on the allowable pitting stress The stress-cycle factor for pitting resistance (pinion), ZN is 0.928 The geometry factor for pitting resistance. , is 01205 The allowable contact stress, ?c, all, is | 14261 | psi The value of the transmitted load, Wt is 712lbf The achievable power based on the allowable pitting stress. H is 18.28 hp. Co Prev 3of 12E Next >
