Cylindrical gearboxes of the Leroy-Somer series Poulibloc They are designed for applications where it is necessary to supply torque directly to the working shaft of the equipment and thereby ensure the compactness of the drive unit. In most cases, Poulibloc gearboxes are used as part of belt or chain gears, the electric motor in these cases is mounted on the frame of the equipment and does not adversely affect mechanical components.
The main criterion in the design of mechanical transmissions, the manufacturer puts the operability of equipment in emergency modes, maintaining operability under "unacceptable" overloads. The overload characteristics of Leroy Somer equipment are 20-30% higher than those of many European manufacturers.
The use of high-strength alloyed materials in the manufacture of all drive elements (gears, shafts, fasteners), high-quality lubricants, corrosion-resistant coatings and seals allows you to minimize maintenance and increase reliability.
Reliability at high radial loads is ensured by reinforced supports and bearings of a larger standard size.
High reliability with minimal maintenance at a competitive price makes customers all over the world prefer Leroy Somer gearboxes.
