The picture shows the rear swivel axle bearing design of a 4-wheel wagon. It is known that the speed of the wagon wheels is n = 37 rpm. The total radial load carried by the wagon is given as Fr= 16060 Newtons. In addition, due to road conditions, Fa axial load is applied to the wagon. If the axial load on the A bearing is 10% of the radial (vertical) load on this bearing, calculate the dynamic load number (C) of the bearing in the A bearing in Newtons for 18616 hours of life. fo*Fa/Co = 0.345 Pi=3.14

A stone crusher machine working 8 hours a day is driven by an electric motor with a narrow-V belt-pulley mechanism. The transmitted power is P = 18.5 kW, the speed of the motor is n1 = 1450 RPM, and the required rotational speed for the stone machine is n2 = 690D / d. Sizing of the narrow-V belt-pulley mechanism is required according to the given. Recommended value for the axle spacing a = k. (dw1 + dw2) k = 0.9
3. Figure 4 shows a simplified schematic of the drive system of joint 4 of the PUMA 560. The torsional stiffness of the couplings is 200 Nt-m/radian each, that of the shaft is 400 Nt-m/radian, and each of the reduction gear pairs has been measured to have output stiffness of 2000 Nt-m/radian with its input gears fixed. Both the first and second reductions have n=4. Assuming the structure and bearing are perfectly rigid, a) What is the effective stiffness of gear 1 if the electric motor's shaft is locked? b) What is the effective stiffness of gear 3 if the electric motor's shaft is locked? c) What is the stiffness of the joint (i.e., when the motor's shaft is locked)? In other words, find out the effective stiffness of the output gear 4. - Electric motor -#1 Coupling Connecting rod #2 Coupling -#1 Gear 42 Gear #3 Gear - #4 Gear Figure 4: Simplified version of the driven train of joint 4 of PUMA 560.

A gear drive is proposed to connect a 30-kW electric motor, with a shaft speed of 1475 r/min, to a uniformly loaded conveyor with a required shaft speed of approximately 531 r/min. Use a pinion with 18 teeth, a pressure angle of 200. and a gear with 50 teeth. Both gears will be made from hardened through grade 2 steel, while the Brinell hardness of the pinion and gear will be 160 BHN. The gears are to be manufactured to a number 9 AGMA quality standard while the teeth are uncrowned. The module of the gears is 5 mm, and the face width is 20 mm. The gears are straddle mounted within a precision enclosed gear unit. Assume a pinion life of 103 cycles and a reliability of 90 %.
