7-25 A shaft is to be designed to support the spur pinion and helical gear shown in the figure on two bearings spaced 700 mm center-to-center. Bearing A is a cylindrical roller and is to take only radial load; bearingB is to take the thrust load of 900 N produced by the helical gear and its share of the radial load. The bearing at B can be a bal bearing. The radial loads of both gears are in the same...
can you please explain how to calculate the axial load for each gear and supporting load for each bearing? thank you! Task 1: A shaft is to be designed to support the spur pinion and helical gear shown in the figure below on two bearings spaced 700 mm center-to-center. Bearing A is a cylindrical roller bearing and has to take only radial load; bearing B has to take the thrust load produced by the helical gear and its share of...
Please answer A and B. The rotating solid stedl shaft is simply supported by bearings at points B and C and is driven by a gear (not shown) which meshes with the spur gear at D, which has a 150-mm pitch diameter. The force F from the drive gear acts at a pressure angle of 20. The shaft transmits a torque to point A of TA-340 N m. The shaft is machined from steel with Sy- 420 MPa and Sut-560...
Figure Q1 shows a gear train consists of four spur gears A, B, C and D to be designed for a specific mechanism. The power transmitted by gear A is 5 kW at rotational speed of 720 rpm counterclockwise direction. Number of teeth (N) for gears A,B,C and D are respectively 20, 50, 30 and 60. The module and pressure angle of the gears are respectively 4 mm and 20o . Determine followings: (a) Tangential and radial forces between gears...
You work for a gearbox company and have been charged with helping to design a geared countershaft for a speed reducing gearbox. The gearbox consists of a compound reverted gear train as shown below and is to be designed for an exact 16:1 speed reduction ratio. The input motor provides 10-horsepower which is carried through the gear train and operates at a speed of 2,000 rpm. You are asked to consider spur gears with a 20° pressure angle and 4...
Design Problem. Please have a detailed procedure. the location of gear mesh, is in the perforated supports Un eje de acero AISI 1020 soporta una carga transversal de 7 kN y transmite un eje por resistencia y deflexión. Si la mayor inclinacion rad y en el acoplamiento del contra el daño por distorsión? ¿Cuál es el factor de seguridad que protege contra la falla por fatiga, utilizando el criterio ED-Elíptico? Si el eje resulta insatisfactorio, ¿qué recomendaría para corregir el...
power = 3 kW if need any more information please ask !!! You are the designer and you have been asked to design a speed reducer (gearbox) that will take power from the shaft of an electric motor rotating at 1500 rpm and deliver it to a machine that is to operate at approximately at 200 rpm Assume that you have decided to use spur gears to transmit the power [A power equal to the last one digits of your...
