Two coaxial shafts A and B are geared together through an intermediate parallel shaft C. The wheels connecting A and C having a module of 2 mm and those connecting C and B have a module of 3.5 mm. Speed of B is less than 1/10th that of A. If the two pinions have each 20 teeth, find suitable number of teeth for the wheels to improve the performance of the mechanism, the actual velocity ratio, and corresponding center distance of shafts C and A.
The pitch circle diameter of the smaller of the two spur wheels which mesh externally and haveinvolute teeth is 100 mm. The number of teeth are 16 and 32. The pressure angle is 20° and theaddendum is 0.32 of the circular pitch. Find the length of the path of contact of the pair of teeth.
The gear ratio shown must transmit 10 horsepower (66000 lb in/s) from its input, which is rotating at a speed of 1200 revolutions per minute. It must increase the torque received at its input shaft 16 times. Spur gears with 20° pressure angle should be used. Input and output shafts should be aligned. The transmission should take up as little space as possible. The distance between the centers of the input shaft and the intermediate shaft (the one that loads gears 3 and 4) should be 10 inches. Determine the magnitude of the radial load that gear 4 exerts on gear 4. Write your answer in pounds.
