What about the spiral bevel gears and spiral bevel gears?
The spiral bevel gear with high efficiency, stable transmission ratio, arc overlap coefficient, high bearing capacity, stable transmission, reliable work, compact structure, material saving, space saving, abrasion resistance, long service life, low noise. In all kinds of mechanical transmission, the spiral bevel gear transmission efficiency is the highest of all transmission especially high power transmission has great economic benefits; the need to transfer the same torque transmission a transmission pair, space, belt, chain drive than the space required for small size; spiral bevel gear ratio permanent, stable transmission ratio is often the basic requirements of transmission of the transmission properties of the various types of machinery and equipment; spiral bevel gear, reliable work, long service life.
So you're talking about the two term for the same kind of gearThere is also called bevel gear or bevel gear (Note: less spiral word), and it is the basic difference between spiral bevel gear is: bevel gear tooth shape without spiral angle, spiral bevel gear tooth shape has spiral angle (see Figure)
The spiral bevel gear has an arc shape, a spiral angle, and a conical tooth shape (see Figure)Because the tooth surface of spiral bevel gear is very like an umbrella, it is also called spiral bevel gear, arc tooth bevel gear, spiral bevel gear, circular arc bevel gear and so on
