PGRF series planetary gearbox

An Indian client sought to upgrade their company's collaborative robot (cobot) arm. To handle a 25kg payload, the joint module required a high-precision right-angle planetary gearbox with a rated output torque of ≥ 150 Nm and a low backlash of ≤ 5 arcminutes. Additionally, due to the extremely compact design of the joint, the customer required the axial length of the speed reducer to be ≤ 120 mm.

After a comprehensive analysis of these mechanical constraints, our engineering team recommended the PGFR090 right-angle planetary gearbox. With its space-saving disc output design and high torque density, it perfectly resolved the client's space limitations while fully meeting their payload capacity and precision requirements.

Structural Advantages

The PGFR090 series features an industrial-standard flange output design complying with ISO 9409-1 standards. Equipped with 7-M6 threaded holes and a Ø6 H7 positioning pin hole on a Ø50 mm pilot circle, this right-angle speed reducer allows for direct, keyless mounting to robot joint modules, end-effectors, and rotary indexing tables without requiring expensive custom adapters.

To meet diverse gear ratio requirements, the PGFR090 is available in both L1 and L2 stages:

L1 (Single Stage): Offers compact integration with standard reduction ratios (e.g., 3:1 to 10:1).
L2 (Double Stage): Engineered for higher gear ratios (e.g., 12:1 to 100:1) with an axial length extension of only 28 mm, maintaining a highly compact footprint even under maximum torque multiplication.

Designed with modularity in mind, the PGFR090 features an adaptable input end (with customizable C1 to C10 mounting dimensions). Our square input flange (C7) and clamp-style coupling can be custom-machined to seamlessly match any mainstream servo or stepper motor (such as Panasonic, Yaskawa, Mitsubishi, and Delta), ensuring hassle-free installation and optimal power transmission.

Thanks to our customizable modular input flange (supporting C1 to C10 interface standards) and clamp-on coupling, it can be customized to seamlessly match standard servo and stepper motors (typically ranging from 400W to 1000W) from leading global brands like Panasonic, Yaskawa, Delta, and Mitsubishi.

Q: Is the PGFR090 planetary gearbox suitable for high-load applications?

A: Yes. The PGFR090 features a robust disc output flange supported by high-capacity internal bearings, delivering a maximum axial load of up to 2000 N and a high torsional rigidity of 30 Nm/arcmin. It handles a rated output torque of up to 335 Nm (depending on the reduction ratio), with an emergency stop torque limit of 3.0 times the nominal torque. This rigid structure ensures high impact resistance and stable transmission in demanding robotic joint movements and automated production lines.

Q: What noise level does the PGFR090 series generate, and is it suitable for quiet environments?

A: Yes, it is highly suitable. Thanks to optimized helical gear geometry and precise tooth grinding, the PGFR090 series operates at a very low noise level (typically ≤ 60-65 dB at nominal speed). This makes it an ideal choice for noise-sensitive environments, including medical automation, laboratory testing equipment, and high-end semiconductor processing machinery.

Q: Can the PGFR090 series be installed both horizontally and vertically?

A: Absolutely. The PGFR090 planetary gearbox supports 360-degree mounting (including horizontal, vertical, and inverted orientations).
