Series

The E series represents a wide range of TwinSpin® high precision reduction gears with a flange shaped case. The E series high precision reduction gears comprise an accurate reduction mechanism and high-capacity radial and axial cylindrical bearings. This design of reduction gears allows the mounting of the load directly on the output flange or the case without the need for additional bearings. The E series high precision reduction gears are characterized by a modular design, which allows the mounting of desirable motor type to the reduction gear by means of a motor connection flange. The E series includes TwinSpin® high precision reduction gears that are not completely sealed; an inlet flange and a gasket kit have to be used for the sealing. Upon the customer’s request, SPINEA® is able to supply a completely sealed reduction gear with a flange according to the customer’s motor.

RIGHT TO CHANGE WITHOUT PRIOR NOTICE RESERVED

1/ Mean statistical value. For further information see chapter Torsional stiffness, Tilting stiffness.
2/ Load at output speed 15 rpm.
3/ Tilting moment Mc max value for Fa=0. If Fa ≠0, see chapter Tilting moment.
4/ Axial force Fa max value for Mc=0. If Mc≠0, see chapter Tilting moment.
5/ The effective speed can also be higher for lost motion bigger than 1 arcmin and for low values of oil viscosity. For lost motion lower than 0,6 arcmin please consult the effective speed with the manufacturer.
6/ The parameter depends on the version of the high precision reduction gear.
7/ The parameter depends on the version of the high precision reduction gear, ratio and lost motion.
8/ The values of the parameters are informative. The exact value depends on the specific version of the high precision reduction gear.
9/ Temperatures of the high precision reduction gear lower than 20°C will cause higher no-load starting or back driving torque.
10/ Depends on the duty cycle; a higher input speed may still be possible; please consult the manufacturer.

The ratios highlighted in bold are recommended by SPINEA as optimal versions in terms of price and delivery.

Important notes:

• Load values in the table are valid for the nominal life of L10 =6000 [Hrs].
• High precision reduction gears are preferred for intermittent cycles (S3-S8); the output speed in applications is inverted-variable. The continuous mode cycle (S1) is needed to be consulted with the manufacturer.
• Dimensional pictures of the T series reduction gears are listed in the catalogue without sealing.
• Sealing options are decribed in chapter Assembly instructions.
• Please consult the the maximum speed in a duty cycle with the manufacturer.
• The values in the table refer to the nominal operating temperature.
