Angular Spiral Bevel Gearbox

The compact design of MPS Spiral Bevel Gearboxes produces less vibration and less noise than conventional gearboxes, which uses straight-cut or spur-cut gears with straight teeth. The advantages of a bevel gear over a worm gear are that it has a higher efficiency level. Spiral bevel gears have spiral angles, which give performance improvements. They are designed for an angle change of 90 degrees, where the two axes are concurrent and in the same plane. They are the most complex forms of bevel gears. These gears have a double function of being helical and bevelled at the same time. The contact between the teeth starts at one end of the gear and then spreads across the whole tooth. The teeth are curved by cutting them obliquely, resulting in higher overall contact ratios. Because of higher contact ratio, these have better load carrying capacity and this allows them to be smaller in size for a given load capacity than an equivalent gear. Thus they can transmit more power with smaller gears.
