Planetary gears

Planetary gear units complement the servomotors to form a complete drive axis
Maximum precision, dynamics, and high torque density are essential demands that are placed on a reliable planetary gear unit in practice. The parameters that are important for the design of a planetary gear unit – the inertia ratios, the required torques and the motors that can thus be used – can be calculated very conveniently in TwinCAT with the TwinCAT 3 Motion Designer. In addition, the tool checks in a single work step whether the selected motor can be adapted to the gear unit. The planetary gear units are fitted to the respective motor in the factory and delivered as a complete motor/gear unit.

application parameters

Precision gear units to suit every application
The Beckhoff planetary gear units are matched to the servomotors from the AM8000 series and offer a wide range of choices for the most diverse applications. The AG2300 and AG2400 high-end gear unit series offer finely scaled, single-stage, and multi-stage transmission ratios between i = 3...100. The various sizes with a high-efficiency are particularly suitable for technically demanding drive solutions. The range of applications extends from the high-precision axis in machine tools and manufacturing machines through to highly dynamic packaging machines, where maximum productivity is required.
The cost-effective alternative from the economy segment
In parallel with the high-end series, the planetary gear units from the AG3210, AG3300, and AG3400 economy series represent a low-cost, but technically high-quality alternative. Primarily for applications in the price-sensitive range, Beckhoff offers two versions in each of the three economy series:
the standard variant for applications with high positioning accuracy
the high-torque variant for applications with high torque requirements
The planetary gear units from the economy series are suitable for the most diverse applications due to a variety of transmission ratios and output variants and open up new design freedoms for the machine manufacturer.
Planetary gear units for AM8800 stainless steel servomotors
The AG8800 low-backlash planetary gear units in a hygienic design meet the strict requirements for hygienic production and packaging machines. The main feature of the gear unit series certified by the EHEDG is the safe and efficient cleaning of the gear unit. The new concept opens up completely new freedoms for the design engineer in the design of plants with the highest requirements for hygienic and sterile production.
Planetary gear units for compact drive technology and stepper motors
The low-backlash economy planetary gear units from the AG2250 series, in straight and angled versions represent with a variety of tra
