Help and Information

Mounting Position

GST Mounting Position

The GST Helical gearbox mounting position determines the oil fill level and the appropriate vent location.

It is very important that the correct mounting position is specified when ordering, if a gearbox is fitted in a position other than the one specified on the name plate then it’s very likely that oil starvation will occur on some gears and bearing with catastrophic failure or the unit.

Please see chart below and check the GST helical gearbox or geared motor before installation as incorrect mounting position would void warranty.

**A = B3
Lenze Gearbox Mount Position A - B3
B = B8
Lenze Gearbox Mount Position B - B8
C = V5
Lenze Gearbox Mount Position C - V5
D = V6
Lenze Gearbox Mount Position D - V6
E = B7
Lenze Gearbox Mount Position E - B7
F = D6
Lenze Gearbox Mount Position F - D6

** Please note Lenze use mounting positions A to F. We have included the IEC reference next to each mounting position

Identification

Lenze GST Helical Geared Motor Identification.

It is most important when purchasing a replacement Lenze GST Geared Motor that the unit is identified correctly, the Lenze GST modular makeup means an infinite number of options available and many of the options are not always visible.

Fortunately Lenze assign a unique number to each geared motor that identifies the unit exactly, because the number is unique to your geared motor it ensures an accurate quote for a replacement and peace of mind that the replacement unit will fit and perform exactly as the original.

The name plate below shows the position of the identification number.

Lenze GST Nameplate

The number will always be 8 digits and it will start:

15****** = Standard Unit

13****** = Modified Unit

The above style of nameplate has been used for approximately 8 years but if the plate is silver as below the unit will have 2 nameplates one for the motor and one for the gearhead again using an 8 digit unique identification number and starting 15****** or 13****** we need the details off both nameplates for correct identification.

These numbers and a photo if not sure of identification can be uploaded here on our Contact Us page

Lubricants

Lenze GST helical gearbox and geared motors are ready for operation on delivery and are filled with lubricants specific to both the drive and the design. The mounting position and design specified in the order are key factors in choosing the volume of lubricant.

The lubricants listed in the lubricant table are approved for use in Lenze drives.

Installation

Danger!

Electrical connections must only be carried out by skilled personnel

This documentation is directed at qualified skilled personnel according to IEC 60364. Qualified skilled personnel are persons who have the required qualifications to carry out all activities involved in installing, mounting, commissioning, and operating the product.

Motor Connection

To correctly connect the motor, please observe:

  • The notes in the terminal box of the motor
  • The notes in the Operating Instructions of the motor
  • The technical data on the nameplate
GST Operating Instructions

Operating Conditions

The Lenze GST Helical Gearbox and Geared Motors are designed to be operated in the following conditions to obtain its full operational life, should your application fall outside the stated conditions then operational life could be adversely affected. Please click link below to see exact operational limits or call Transdrive sales desk for guidance.

The powers, torques and speeds specified in this website are rounded values and are valid under the following conditions:

  • Operating time/day = 8 h (100% OT)
  • Duty class I for up to 10 switching operations/h
  • Mounting positions and designs in this catalogue
  • Standard lubricant
  • Tamb = 20 °C for gearboxes,Tamb = 40 °C for motors (in accordance with EN 60034)
  • Site altitude <= 1000 m amsl
  • The selection tables provide the permissible mechanical powers and torques. For notes on the thermal power limit, call Transdrive or see Lenze High Effiecency GST Catalogue from 0.75kW
  • The rated power specified for motors and geared motors applies to operating mode S1 (in accordance with EN 60034).

Load Capacity C

C is the load capacity of the gearbox, this is determined via several variable factors.

  • Number of hours per day the unit is operated
  • Number of starts per hour
  • Load Type see below

Load Type

  • Duty I = Smooth operation, small or light jolts
  • Duty II = Uneven operation, average jolts
  • Duty III = Uneven operation, severe jolts and/or alternating load

It is important to select the correct load capacity C of the gearbox as this ensures the gearbox is robust enough to give its full service life, incorrect selection could result in premature failure of the gearbox or oversizing with a larger and more expensive gearbox being selected than required.

As a rough guide with 8 hours per day running and no more than 10 starts per hour with correct oil selection and ambient temperature, then a selection of C as below would be suitable.

  • Duty I 1.0 to 1.4
  • Duty II 1.4 to 1.6
  • Duty III 1.6 to 1.8

For a full and technical explanation of load capacity C please see below or call Transdrive for further advice.

Load capacity diagram

Load Capacity and application Factor

Load capacity of gearbox

Rated value for the load capacity of Lenze geared motors

  • c is the ratio of the permissible rated torque of the gearbox to the rated torque supplied by the drive component (eg. The build in Lenze motor)
  • The value of c must always be greater than the application factor k calculated for the application.

Application factor k (according to DIN 3990)

Take into account the influence of temporally variable loads which are actually present during the atnticipated operating time of gearboxes and geared motors.

k is determined by:-

  • the type of load
  • the load intensity
  • temporal influences
