The highly dynamic servo-right angle gearbox

Internal highlights The design of the DynaGear range has been influenced by extremely varied applications within many industry sectors. The DynaGear range has been developed with a highly dynamic servo drive solution in mind and therefore benefits from many advantages. Weight efficient one-piece Aluminium housing ensures highest stability n Right angle gearbox, single-stage, ratios from High-quality taper roller bearings absorb axial and radial loads guaranteeing a long service life 3 : 1 to 15 : 1, two-stage up to 100 : 1, higher ratios on request. n The compact and rigid design ensures...

External highlights The DynaGear realises the theme “Motor – Coupling – Gearbox – Mounting” in a unique way. n The DynaGear fits all current servo motors by way of flanges and couplings to suit. n Torsional vibration can be adjusted via the coupling stiffness. n The gearbox dimensions are identical for all ratios. Solid shaft version with continuous shaft, coupling and input flange Compact and weight efficient aluminium housing Easy mounting without additional parts Hollow shaft version with coupling and input flange Couplings and adaptor flanges to suit all motors Subsequent motor type...

Technical service and maintenance DynaGear and DynaGear Economy Gearboxes DYNAGEAR gearboxes are supplied ready lubricated for life with a high-quality synthetic oil to CLP DIN 51 517, ISO VG-Class 150 (DIN 51 519). They are therefore maintenance free. We recommend that for continuous operation close to the thermal performance limit, regular leak controls are undertaken on the shaft seals. After approx 15.000 operating hours, it is advisable to change the oil. Please request instructions which also include advice on lubricants and quantity. Service kits of wear and tear parts with full...
