In a gear set, a 36-tooth spur pinion drives a 60-tooth spur gear. The teeth of these gear are cast iron profile. The diametral pitch is 6-teeth/in, the face width si 0.5 inches, and the pressure angle is 20 degrees. Assume that the pinion transmits 10 hp at a speed of 2000 rpm. Find the pitch diameters of the gears. Find the pitch line velocity in ft/min Find the velocity factor Ky Find the tangential load in lbf Find the contact stress in kpsi, assuming CP=1960 psi.

Problem 1. The spur gears shown in the figure have a diametral pitch of 2 teeth per inch and a 20 pressure angle. The pinion rotates clockwise at 1200 rev/min and transmits 150 hp through the idler pair to gear 5 on shaft e. What forces do gears 3 and 4 transmit to idler shaft? 327 187

In a spur gear arrangement, the driver has 80 teeth of 39 mm pitch. Find the power, if it can transmit a tangential force of 60 N. Take speed of driver as 150 rev/min. Insert your answer for power in watt correct up to at least a third decimal place.

A gear box has an input speed of 1,809 rev/min clockwise and an output speed of 475 rev/min anticlockwise. The input power is 49 kW and the efficiency is 0.77. Determine the input output Power in kW

The diagram below shows a shaft with spur gear (B), bevel gear(D), and two supporting bearings (A and C). All dimensions are in millimeters and all shoulder fillets (at points where diameter changes) have a radius of . The pressure angle for the spur gear at B is . The pressure angle for the bevel gear at D is  and the bevel angle is . Note that the shaft is designed so that only bearing A takes thrust. The shaft is made of steel with . All the critical surfaces are ground. The shaft rotates at . A motor with a power of  is connected at the bevel gear through another bevel gear. This drives the shaft. A load is connected through another spur gear at the output spur gear at B. The standard deviation on the power is . (a) Determine the forces acting on the gears. Recall that for a spur gear, the relation between the tangential component of the force and the radial component of the force and the pressure angle is given by . For this bevel gear, the axial (thrust) component of the force on…

8. A pinion gear with 15 teeth turns at 200 rpm ('revolutions per minute). It is driven by a larger gear having 60 teeth, What is the rpm of the larger gear? (Hint: Write a proportion showing that the products of the number of teeth and the speed (rpm) of each gear are equal.) O O O O 50 75 600 800
