Compared to other common types of gears, bevel gears are specially made to transmit energy between intersecting axes. One of the most common alignments of bevel gear is perpendicular, making it possible to alter its operating angle. Their surface pitch, or otherwise called the teeth bearing surface, is conically tapered or shaped. The mechanical advantage of this tooth alignment can be altered by varying the number of teeth or diameter on each of the gear wheel. The ratio of gear tooth between the drive and driven wheels can either be increased or decreased. As such, it is possible to also modify the rotational drive and torque of the wheels.
When it comes to the relationship between speed and torque, the latter decreases when the former increases, and the opposite is also true. Bevel gears tooth alignment can be done in various ways. It can be straight that looks very similar to spur gears but they have teeth that narrow towards the apex. However, this alignment tends to be loud caused by the abrupt contact between the meshing teeth. The other option is the spiral tooth alignment that looks identical to helical gears with angled teeth in zero.
The third option is the hypoid bevel gears that appear the same as that spiral gears but their difference is on the mating gears which don’t have intersecting axes. This allows for a smoother engagement and bigger pinion. The last tooth alignment is the crown gear which, basically, looks like points of a crown. They have pitch angles of 90 degrees and parallel with the axis. The wide selection of our gear products has undergone a strict quality inspection process to ensure only the best production of the gears. Just give us a call to learn more about your options.
