A worm & worm wheel gear is connected to a motor running at 1000 rpm. Further 03 a gear train is formed using worm wheel having 100 teeth and module of 2mm as a driving gear. Gear “A” having 80 teeth is concentric with the worm wheel which in

turn drives gear “B” in a ratio of 1:1. Gear “C” having 60 teeth and “B” are compound gears. Gear “C” is the driving gear for a simple gear train having one idler gear “D” with 40 teeth. Sketch the gear arrangement and determine:

i. Speed of the output gear “E” having 40 teeth.

ii. Center distance between the worm and output shaft if a worm is having single start thread with a diameter of 20 mm and gear “A” & “B” are spur gears having module of 3 mm and all the gears of simple gear train are helical gears having a module of 2 mm.

23 hp, dc shunt motor is running at 1000 rpm when the armature voltage is 600 V. The armature resistance of the motor is 0.8 ohm, and the field resistance is 900 ohm. The efficiency of the motor at full load is 92 %. a) Calculate the value of the resistance of the dynamic braking at full load. The armature current should be limited to 150% of the rated value. b) If the motor operated in regenerative braking at a...

A DC shunt motor drives a centrifugal pump at a speed of 1000 rpm when the terminal voltage and line currents are 200 V and 50 A, respectively. Given the armature resistance, Ra = 0.1 ohm and field resistance, Rf =100 ohm. Design a circuit which the speed of the motor can be controlled by using the added resistance method to the armature circuit and the maximum starting current is 120 A. Next, if the added resistance in the designed...

15.33 A spur gear reducer has an 18-tooth pinion driven 1500 rpm by an electric motor and a 36-tooth gear that drives a load involving “moderate shock.” A life of 106 pinion revolutions is required, and the transmitted load, Ft, is 100 lb (this figure includes a safety factor of 2). Conditions are such that Km = 1.8 and kt = 1. It is proposed that standard 20° full-depth gears be used, with both pinion and gear teeth being cut...

6. A motor car, of a total mass 1400 kg, running in top gear at 55 km/h, passes on to a rsing gradient of 1 in 20 at that speed. The road and other resistances may be taken as constant at 270 N/t. With condition unchanged, the speed falls uniformly to 40 km/h in a distance of 360 m. An intermediate gear is then engaged for which the speed ratio between the engine and the road wheels is 9:1 and...
