SPN bevel gears are manufactured according to your drawings. You have the choice between robust straight teeth or smooth-running spiral teeth. Different materials and hardening processes round off the offering.

Bevel gearing is a gear wheel arrangement in which the teeth are positioned along the surface of a conically shaped cone. The bevel angle, which defines the angle between the axes of the bevel gears, influences the transmission of the rotary motion.

With bevel gears, any axis angle can be produced. However, right angles are preferred for many applications.

The teeth of the bevel gears engage in a precisely calculated mesh to ensure smooth and efficient power transmission. This type of gearing is used in various mechanical systems, including transmissions, vehicle differentials and final drives.

The arrangement enables a variable transmission ratio, which is crucial in many applications. The compact design of bevel gears makes them particularly space-saving and versatile. Special toothing shapes such as spiral toothing are often used to reduce noise.

The precise manufacture and alignment of the bevel gears, as well as their reliable bearing support, are crucial for efficient function and durability in technical applications.

A bevel gear is a gear consisting of two conical gears whose teeth are arranged on the wheel surface. The tooth height is the vertical size of a tooth profile from the base circle line to the tooth tip. The tooth root height is the distance from the base circle line to the tooth root line.

The respective amounts increase the more you move outwards on the taper line.

  • The tooth width (b) indicates the radial width of a tooth, measured along the cone generatrix.
  • While the pitch (p) describes the distance between two consecutive teeth on the same taper circle line.
  • The module (m) represents the ratio between the pitch and π.
  • The transmission ratio (i) is the ratio between the speed of the driving wheel and that of the driven wheel.

In addition, the angle between the axes of the bevel gears is referred to as the bevel angle. This angle influences the way in which the forces are transmitted between the wheels. There are any number of bevel angles, but the majority of bevel gears are in the 90° range.
