Q2: A speed reducer unit is to be designed for an input of 1.1 kW with a transmission ratio 27. The speed of the hardened steel worm is 1440 r.p.m. The worm wheel is to be made of phosphor bronze. The tooth form is to be 20° involute. Given data: the centre distance (x) = 100 mm. Draw complete construction of the system showing all missing parts, i.e. keys, bearings...etc, with necessary mountings and fixations. (Put the main dimension). Assume suitable missing dimensions or data if any.

For the Finishing Mill of a hot strip mill, the input shaft of several different gearboxes are each driven by a DC motor of 10,500 HP operating at 125 RPM. For your ASSIGNED gearbox only, you are required to analyze the gearbox capabilities by doing thefollowing: 1. Calculate the maximum motor torque2. calculate the force transmitted by the gearing.3. Using statics, calculate the equivalent radial load at the bearings for BOTH the pinion shaft and the gear shaft. (Four bearings total; two per shaft). Include FBDs of the shafts.4. Research the load capacities for the bearings.(Hint: the bearing manufacturer is most likely Timken / Torrington).5. Calculate the expected bearing life for each bearing.6. Calculate the safety factor for both the bending strength and the pitting resistance for the pinion shaft AND the gear shaft gear teeth based on the transmitted load and the gear material(s).7. Draw the shear, bending moment, and torque diagrams for the GEAR SHAFT ONLY.8. Calculate the…

A 500 pound weight is attached to a cable that is being lifted by a 10 inch diameter drum. The 48V DC motor selected has a no-load angular velocity of 800 RPM and a stall torque of 500 inch-pounds. A gearbox has been designed to spin the drum as quickly as possible. Assume that there are no friction losses in this system. The drum is driven by a 72-tooth gear with a diametral pitch of P=8, and is 3D printed such that it has a yield strength in shear of τy = 2500 psi. Assuming that the entire output torque required to turn the drum is produced by the force on one tooth, and that the gear tooth would fail by being sheared off at the pitch circle, determine the required gear face width, b, for a factor of safety of 3. Note that circular tooth thickness, t, at the pitch circle is π / (2P). Repeat for a gear made out of 6061 Aluminum (σy = 35 ksi, τy = 20 ksi). Only do the part for the 6061 gear do not do it for the 3D printed gear
Starter is used to transmit initial mechanical power to the car engine and the analysis will be based on this initial power input. Starter power is 1 hp, rotates at 250 rpm and has 10 teeth. The crankshaft has 48 teeth and camshaft has 60 teeth. Determine torque delivered by the camshaft? If the timing belt has 10 teeth/in, find its speed in in/min?
