2. A 75 kW induction motor runs at 740 rpm in clockwise direction. A 19 tooth helical pinion with20 degree normal pressure angle, 10 mm normal module and a helix angle of 23 degree is keyed to the motor shaft. Draw a 3-dimensional sketch of the motor shaft and the pinion. Show the forces acting on the pinion and the bearing at A and B.

Problem 13.049 - Bearing Reactions for Beveled Gears The figure shows a 16T 20° straight bevel pinion driving a 32 T gear and the location of the bearing centerlines. Pinion shaft a receives 2 hp at 200 rev/min. Determine the bearing reactions at A if it is to take both radial and thrust loads. Problem 13-43 Dimensions in inches. The bearing reaction due to radial load FA, radial is | B 4 Ibf and the bearing reaction due to thrust load FA, thrust is Ibf.

Figure Q4 shows a Mach trim system from a 737-800. It consists of a hydraulic motor driving gear A which drives gear B. Gear B is directly connected to the horizontal stabiliser via rack and pinion as depicted below. Gear A has a mass of 6kg, a radius of gyration of KGA = 0.1235m and an angular acceleration of 20kg, and a radius of gyration of Ö = 0.2t rad/s². Gear B has a mass of m = m = = 0.5341m. If the system starts from rest, determine the following when t = 3s: KGb a) The velocity of the gear rack. b) The distance the rack has travelled. c) If there is a contact force between the rack and gear B of 50N, determine the contact force between Gear A and B. d) The applied torque from the hydraulic motor. 100mm 500mm B 200mm Figure Q4-Mach Trim System tastes ins

A four-part mechanism like this one, if it is known the length of o2a (link 2) is 5 cm (link 3) is 4 cm (link 3) and the length of the bo4 (link 4) is 5.5 cm (5 in.). At the a point working the p = 50 Newton style with the sustric orientation of the horizontal line is 20⁰, look for styles that are going on and torque on link 4.
