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 a need of additional bearings. The E series high precision reduction gears are characterized by a modular design, which allows the mounting of your desirable type of motor 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.

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.

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