De levertijd verkorten

Wanneer een bestelling wordt geplaatst, worden de beschikbaarheid van de onderdelen die nodig zijn voor het eindproduct en de productiemogelijkheden gecontroleerd. Na bevestiging is expressproductie mogelijk binnen de verkorte levertijd tegen een meerprijs.

Housing design

The following housing versions are available:

1. 1.A - push-on version, mounting with rubber buffer is recommended (see components)

1. 2.B - Push-on version - as A, plus bolt circle with threaded holes on both sides of the gearbox output

1. 3.C - Flange version C - for mounting the gearbox on the side output flange

Dimensions: see dimension sheet

Installation position

The installation position is required to determine the lubricant quantity.

The designations for the various installation positions can be found in the following illustration.

Shaft design

1 outer ring
2 Clamping screws
3 Inner ring
4 Hub
5 Shaft
6 Grease-free

Additional housing and shaft options

Double seal on the output shaft:

Depending on the available installation space, a combination seal with one NBR and FKM sealing lip each or two sealing rings in NBR and FKM design are used.

Advantages:

• - Optimum sealing properties at high operating temperatures thanks to FKM seal

• - Good sealing properties at low temperatures due to NBR seal

• - Better protection against high levels of soiling thanks to 2 seals (the outer seal also has a dust lip)

• - High level of safety and improved stability against oil leaks thanks to additional sealing lip

Use is recommended for

• - Critical installation positions

• - Where there are special requirements for the reliability of the seal

Reinforced bearing of the output shaft

With this option, the permissible radial forces for the output shaft can be increased.

Further information on determining the radial force and the permissible values for

standard and reinforced bearings in the PDF document Notes on selecting options

Rubber buffer for housing

Selection for slip-on version A. For elastic mounting (torque support) of the geared motor. Suitable for the hole on the front of the gearbox housing.

Mounting kit for hollow shaft

for mounting "customer shafts" with and without collar.

Further information in the PDF document Notes on selecting options

Protective cover for hollow shaft

Only possible with slip-on version B and flange version C. Fastening on existing threaded holes on the gearbox output.

Second shaft end

Standard version - without

Second shaft end - cylindrical shaft with keyway

Dust and water protection

Selectable options:

IP55 - dustproof, protection against water jets (standard)

IP65 - dust-tight, protection against water jets

IP65 with brake - as before, but with additional brake version in IP65

IP code for the degree of protection in accordance with DIN EN 60529, 60034-5,

First code number: Protection against ingress of foreign bodies

Second code number: Protection against ingress of water with harmful effects

Voltage/frequency

Selectable options:

230/400V/D/Y, 50Hz (standard)
Possible applications: In star connection (Y) directly on 400V mains, in delta connection (D) on frequency inverters with output voltage 230V/3~ or on frequency inverters with output voltage 400V/3~ and operation with 87Hz characteristic curve

400/690V/D/Y, 50Hz
Possible applications: In delta connection directly on the 400V mains, and on frequency converters with output voltage 400V/3~, star-delta start-up with switches or contactors

230/400V/D/Y, 50Hz // 460V/Y, 60Hz

290/500V/D/Y, 50Hz (up to 4kW possible)

500V/D, 50Hz (from 5.5 to 45kW possible)

Motor protection

The following options are available for monitoring the winding temperature of the motor:

a) 1 set of PTC thermistors - for monitoring with PTC thermistor tripping device or frequency inverter

b) 1 set of temperature switches (bimetal) - for monitoring e.g. with motor protection relay

The selection of one of these options is recommended when operating the geared motor on the frequency inverter, as reduced speeds and the associated lower cooling capacity can cause the motor to overheat.

Brake

The available brake types with max. possible braking torques are displayed for selection.

The following additional information is required to specify the brake:

Brake voltage

a) 230V/50Hz/1~

b) 400V/50Hz/3~

c) 24V (DC)

Braking torque at the drive motor (multiplication by the transmission ratio i results in the braking torque at the output shaft),

Manual release for the mechanical release of the brake via a lever, e.g. for adjustment or maintenance

Further information and technical data on the brakes can be found in the PDF document Notes on selecting options

Color shade

Other colors are also available on request for larger quantities.

Lubricant

The following lubricants can be selected as an option:

0 Ambient temperature

1) Load capacity O=normal, +=high, ++=very high

2) Ageing resistance O=normal, +=high, ++=very high

If option 2 is selected, protection class IP65 must also be selected!

Bleeder valve

For relieving pressure in the gearbox. Relieves the sealing rings and prevents leaks.

Standard version from gearbox size F3.

Fan cover with protective roof

When installed vertically, the canopy prevents the ingress of foreign bodies or liquids.
ingress of foreign bodies or liquids.

Condensation drain hole
Depending on the installation position of the motor, the condensation holes are located on the lower side of the motor.
