- State the formula and standards relevant to the single step-up spur gearbox of 10kW rotating at 1000rpm with output speed of 1700rpm.Its materials are pinion with 20 teeth (655M13) and gear(817M40)State the formula and standards relevant to the single step-up spur gearbox of 10kW rotating at 1000rpm with output speed of 1700rpm. Its materials are pinion (665M13) and gear 817M40)Note: If you don't know the solution please leave it but don't give me wrong solution. A flat open belt drive is used to transmit a power of 25kW from a motor shaft rotating at 950 rpm. The radius of the pulley of the motor shaft is 125mm while the radius of the puller of the driven shaft is 450mm. The center distance between the shafts is 2,250mm. the coefficient of friction is 0.25 and the density of the belt material is 950 kg/m^3. The belt width is 126 mm. The allowable stress is 2.6MPa. Determine the thickness of the belt.
- A V-Belt drive is designed so that it has the input sheave on the shaft of an electric motor (normal torque) rated at .55 hp at 1160 rpm full-load speed. The drive is to a bucket elevator that is to be used 12 hours daily at approximately 675 rpm. The center distance is about 19.5 in. Add the detailed steps of your design to your attached worksheet. Hints: 1) In your design choose an appropriate belt section, specify the small pulley diameter, the large pulley diameter and the length of the belt. Determine the Belt length in inches, in two significant figures. Please enter below a numerical value only, no units are needed. Answer:Minimum number of teeth for involute rack and pinion arrangement for a pressurt angle of 20° isDetermine the time required for the compound pulley shown in Fig. P-1224 to reach a speed of 600 rpm starting from rest.

- The client requires a single step-up spur gearbox to transmit a 10 kW power from a shaft rotatingat 1000 rpm, while the output speed must be 1700 rpm. The material for gear and pinion is 817M40and 655M13, respectively State formula and standards relevant to the single step-up spur gearbox design2. Chains and belts behave similarly except that chains often have zero tension on the slack side Assume that's the case for this problem. The smaller sprocket transmits 0.6 horsepower and rotates at 200 rpm. Complete a FBD for each sprocket and provide angular and tangential velocities. The small sprocket has 12 teeth and an effective diameter of 1.43 inches. The large sprocket has 31 teeth and an effective diameter of 3.70 inches.The client requires a single step-up spur gearbox to transmit a 10 kW power from a shaft rotating at 1000 rpm, while the output speed must be 1700 rpm. The material for gear and pinion is 817M40 and 655M13, respectively. Use table 6.10 on page 128 to select the suitable gear and pinion. 1.3 State formula and standards relevant to the single step-up spur gearbox design.
