Question 1
A two-stage spur gearbox (zweistufiges Stirnradgetriebe) is driven by an electric motor rotating at n_in = 1,440 rpm. The first gear stage has tooth counts z1 = 20 and z2 = 60; the second stage has tooth counts z3 = 15 and z4 = 75. What is the total gear ratio i_tot and the resulting output shaft speed n_out?
Correct Answer:
i_tot = 15.0 : 1 and n_out = 96 rpm
Question 2
A simple planetary gearbox (Planetengetriebe) operates with a stationary ring gear (feststehendes Hohlrad, z_ring = 72 teeth). The input is driven via the sun gear (Sonnenrad, z_sun = 18 teeth) rotating at n_sun = 3,000 rpm, and the output is taken from the planet carrier (Steg). What is the gear ratio i and the output speed n_carrier?
Correct Answer:
i = 5.0 : 1 and n_carrier = 600 rpm
Question 3
A worm gearbox (Schneckengetriebe) has a single-start worm (Gangzahl z1 = 1) meshing with a worm wheel of z2 = 40 teeth. The drive motor supplies an input power P_in = 2.2 kW at n_in = 1,200 rpm. If the overall gearbox efficiency is eta = 0.75, what is the output torque T_out delivered at the worm wheel shaft?
Correct Answer:
525.2 Nm
Question 4
A servo planetary gearbox with a speed reduction ratio i = 6.0 : 1 and a mechanical efficiency eta = 0.95 is driven by a servomotor producing an input torque T_in = 50.0 Nm. What is the static output torque T_out available at the planet carrier output shaft?
Correct Answer:
285.0 Nm
Question 5
A three-phase asynchronous motor has a rated mechanical power P_N = 5.5 kW at a rated rotor speed n_N = 1,460 rpm. What is the rated mechanical torque T_N at the motor shaft?
Correct Answer:
36.0 Nm
