Important notes
¯ The transmission is made in a force−fitting manner via a clamping connection.
Greases, oils and other substances which reduce the friction factor reduce the
torque to be transmitted which is why these should be avoided in the connection.
¯ The motor shaft diameter must be designed with fit k6.
¯ The motor centering diameter must be designed with fit j6.
¯ With regard to smooth running tolerance of the motor shaft, concentricity of the
centering and axial runout of the mounting flange, the motor must fulfil the
requirements according to DIN 42955 R (reference values for smooth running <
0.025 mm; axial runout and concentricity < 0.05 mm).
