BEGE Helical Gear Motors – Type G & M Lubrication
Lubrication
These lubricants are for ambient
temperatures from -5°C to +40°C The lubricant quantity responds to the mounting
position shown on the name plate and depends on
gear size and mounting position.
Special lubricants: • For extreme low temperatures -40°C to 0°C
• A non toxic lubricant for the food processing
industry, certified to USDA H1 standard
• Further special lubricants on request
Standard lubrication G-series: Mineral lubricant ISO VG220
Standard lubrication M-series: Synthetic lubricant VG460
BEGE Helical Gear Motors – Type G & M 4-stage gear units
4-stage gear units
The 4-stage gear units are designed using two basic 2-stage gear units: • The primary gear unit is always a flange mounting gear unit
• The secondary gear unit can be a foot- or flange mounting gear unit. This depends on the mounting position
Lubricants The lubricant quantities for the 4-stage gear unit can be selected from the same selection table but now specified as primary
and secondary gear unit.
Example:
4-stage gear unit (DS)G55-26 mounting position B3:
Primary gear unit G26 : 0.5 liter
(Always flange mounting so use B5 lubricant quantity)
Secondary gear unit G55 : 4.7 liter
BEGE Helical Gear Motors – Type G & M Efficiency
Gears selection
The correct choice of gear unit starts by determining the required torque. The gear selection lists specify for the respective output drive speed n2 and the theoretical output torque T2n
The power rating of the motor P1n to be installed can then be chosen (include safety margin)
Helical gear motors have a very high efficiency Generally the efficiency for each gear stage is 0,98 < η > 0,95 and 0,95 < η > 0,90 for a gear stage with oil seals
Our experience shows that;
• The total efficiency for a 2-stage gear is η = 0,90
• The total efficiency for a 3-stage gear is η = 0,86
BEGE Helical Gear Motors – Type G & M Criteria
Gears selection
Criteria We recommend consulting with us regarding the operation in detail if two or more of the following points apply:
• Vertical arrangement (mounting position V5 and V1 or V6 and V3)
• Ratio i < 20 helical gear drive
• Drive speed n1 > 1500 min-1
• High ambient temperature > 40°C
• Specific installation conditions apply e.g. gear enclosure, radiated heat, restricted installation space, etc.
BEGE Helical Gear Motors – Type G & M Load type
Drive design Certain details such as motor power, output speed, output torque etc. Are necessary for configuring the drive.
To match the operating conditions the service factor fb needs to be determined.
BEGE Helical Gear Motors – Type G & M Service factor
Gears selection
Drive design Certain details such as motor power, output
speed, output torque etc. are necessary for
configuring the drive.
To match the operating conditions the
service factor fb needs to be determined.
The service factor has to be multiplied by:
• 1.2 for the application with a combustion
wengine drive, with reversing operation and
winstantaneous overloads
• 1.5 for the application with a brake motor
BEGE Helical Gear Motors – Type G & M Radial load at the output shaft
Gears selection
Drive design The radial load at the output and input shaft which is caused by
transmission elements can be calculated with the following formula:
FR2 = Radial load [N]
Td = Torque of the shaft [Nm]
fz = Transmission element factor
fb = Service factor
dw = Mean diameter of the transmission element [mm]
Changing the rotation direction, the loading
direction, or the use of reinforced bearings, can
result in a higher permissible radial load FR2max
BEGE Helical Gear Motors – Type G & M Axial load at the output shaft
Gears selection
Axial load The permissible axial load is 50% of the permissible radial load FR2max.
(The permissible axial and radial load may be applied simultaneous on the output shaft)
Reinforced bearings If the permissible radial/axial load is not sufficient, it is possible to apply reinforced bearings
for the output shaft at additional cost.
If the axial load is higher then the permissible axial load, please contact BEGE
BEGE Helical Gear Motors – Type G & M Maximum permissible radial load on the output shaft
Gears selection
Maximum permissible radial load The permissible radial load effected on the output shaft is given in Newton [N]
The G-series it depends on the power and speed
The M-series it depends on the gear unit size and speed
n2 : Speed of the output shaft [min-1]
P : Power [kW]
BEGE Helical Gear Motors – Type G Maximum permissible radial load on the input shaft
Gears selection
Maximum permissible radial load The permissible radial load effected on the input shaft is given in Newton [N]
Pay attention to radial force when;
• Transmission by v-belt or chain
BEGE Helical Gear Motors – Type G Gear motor with IEC-adapter
Gears selection
IEC-adapter The gear motors can be delivered with an IEC-adapter.
Thereby any motor can be installed with an IEC standard flange (oil sealed motor required)
Advantage: Install a patented magnetic pulse encoder (MIG), which is implemented as an intermediate flange.
With the combination of IEC gear unit / MIG / 3-Ph motor it’s possible to implement a gear motor for;
• Frequency controlled positioning
• Dosing control
• Torque control
• etc.
The mechanical connection between motor and gear is achieved via a toothed coupling (included)
BEGE Helical Gear Motors – Type G Gear motor with IEC-adapter
Gears selection
IEC-adapter The gear motors can be delivered with an IEC-adapter.
Thereby any motor can be installed with an IEC standard flange.
• Simple installation and dismantling
• No frictional corrosion
• Compact design
• Cost effective spare parts
• By using different bores in the toothed coupling, it’s
kpossible to fit different sized motor frames to each gear
