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 the design specification considering the following design factors:1. Functionality2. Stress
A Coniflex, straight-tooth bevel gearset is supported on shafts with centerlines intersecting at a 90° angle. The gear is straddle mounted between closely positioned bearings, and the pinion overhangs its support bearing. The 15-tooth pinion rotates at 900 rpm, driving the 60-tooth gear, which has a di- ametral pitch of 6, pressure angle of 20°, and face width of 1.25 inches. The material for both gears is through-hardened Grade I steel with a hardness of BHN 300 (see Figure). It is desired to have a reliability of 90 percent, a design life of 10° cy- cles, and a governing safety factor of 2.5. Estimate the maximum horsepower that can be transmitted by this gear re- ducer while meeting all of the design specifications given.
A single stage spur gear gearbox has a module of 1.5mm and an input speed of 1500.p.m. and a pinion with 15 teeth. The overall ratio of the gearbox is 6:1 and the gearbox is transmitting a power of 6000W. If the factor of safetv is to be reduced to an absolute minimum acceptable value and the gears are to be made from a material with a Yield stress of 540 MPa, what is the face width of the gears (in mm)
