BEGE Helical Gear Motors – Type G & M Lubrication Lubrication Standard lubrication G-series: Mineral lubricant ISO VG220 Standard lubrication M-series: Synthetic lubricant VG460 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

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 n 2 and the theoretical output torque T 2n The power rating of the motor P 1n 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 n 1 > 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 f b 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 f b 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: F R2 = Radial load [N] T d = Torque of the shaft [Nm] Changing the rotation direction, the loading f z = Transmission element factor direction, or the use of reinforced bearings, can f b = Service factor result in a higher permissible radial load F R2max d w = Mean diameter of the transmission element [mm]

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 F R2max . (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 n 2 : 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)
