Description

Material
Housing, ZnAl4Cu1 die-cast zinc.

Shafts, 1.4301 stainless steel.

Bevel gears, polyacetal (POM) or polyketone (PK).
Version
Housing and shafts, bright.
Bevel gears, injection moulded, straight teeth. Engagement angle 20°.
Polyacetal, white.
Polyketone, ivory-tone.
Note
Polyacetal: Standard material with high hardness grade and low coefficient of friction.
Polyketone: Material with significantly longer service life, higher power transmission and greater security against tooth breakage due to the extraordinarily high wear resistance and very good tribological properties.

Universally applicable and maintenance-free bevel gear drives in six different sizes with the ratio 1:1. The rotation direction is arbitrary. The shafts are mounted in the housing on self-lubricating plain bearings. The axis angle is 90°.

These bevel gears are suitable for manual drives and for temporary power drives at low speeds and with a low load.
Temperature range
-20 °C to +100 °C.
Attention
The torques specified in the tables relate exclusively to the toothing. The shaft diameter, key size, etc. are not taken into account. The permissible load calculations are based on the basic principles of the pitting load capacity of the tooth flanks as well as the occurring tooth root stress. The respective permissible load of a gear wheel depends on so many different factors that the values specified can only be reference values meant to make selection easier. The torque specifications relate to a single tooth. The overlap, which is essential for determining the transmissible torque, occurs depending on the pitch diameter, gear wheel pairing, etc. In the simplest straight tooth cases, an overlap ratio of 1.1 to 1.25 is normal. To increase the overlap, a higher number of teeth with smaller modules is used. A good profile overlap can minimise damage such as pitting.
