Clutches, Brakes, Couplings, and Flywheels

The clutch is described as a machine element used to connect or disconnect two shafts together to transmit torque or power. The clutch works on the principles of friction. The clutch is commonly used in automobiles to transfer power from the driving shaft to the driven shaft.

Question

Given: A winch will be operated by a worm-
worm gear set, as schematically shown below.
The worm will be powered by an electric motor
that rotates at 1,725 rpm. The expected speed of
the worm gear is between 30 and 35 rpm. The
peak torque requirement for the winch is about
4,100 lbf-in, the operating ambient temperature
is 120 °F, and the average output power doesn't
have to exceed 0.7 hp. The winch drum radius is
6 in, and the winch operates 7 to 8 hours a day.
Find: DRAW A FREE BODY DIAGRAM OF THE
SHAFT HOLDING THE WORM GEAR and
explain your reasoning for what you drew. Must
be legible.
Then draw shear, bending, and torque diagrams
for the shaft holding the worm gear and show
the calculations for how you got to those
diagrams. Must be legible.

Ex] A double-threaded right-handed worm gear transmits 15 Hp at 1150 rpm. The pitch of the worm is 0.75 inch and the pitch diam of 3 inches. The pressure angle is 14.5° and the coefficient of friction is 0.12. a) Find the tangential force on the gear. b) Find tangential force on worm. c) Find the separating force Solution: (To be discussed by the Instructor during the lecture period)
A pinion shaft of a machine transmits a torque of 68 Nm to the shaft of gear at a speed of 574 rpm, which is input at pinion gear and its shaft rotates in the clockwise direction. The number of teeth on the pinion and the gear are 38 and 78 respectively, while the module is 6 mm. Assume a pressure angle of 200. Calculate: i) Power transmitted by the shaft of the pinion in W. ii) Torque on the shaft of the gear in Nm. iii) Speed ratio iv) Tangential load on the pinion in N
In a transmission system 25 ° spur gears are used and the number of teeth on each gear is Np=25 and NG=50. Load is applied at the highest point of single-tooth contact. Power source is electric motor and the transmission system drives uniformly loaded conveyors. The overload factor, Ko is:
