RL-S strain wave gears now available

Post navigation

At the HMI trade show we released our strain wave gear (RL-S) as a product in addition to our worm gears (RL-D). The smallest version of the strain wave gear (RL-S-17-N11-00-28-020K0) is used for the fifth axis in the standard joint arms RL-D-RBT-5532S-XX and RL-D-RBT-3322S-XX. The RL-S-17 gear comes in two variations, both have a transmission rate of 28:1:

1. suitable for small motors (like NEMA11 stepper motors, holding torque = 0.1 Nm), output torque max. 1 Nm

2. suitable for slightly bigger motors (like NEMA17 stepper motors, holding torque = 0.5 Nm), output torque max. 3 Nm

The biggest available joint is the RL-S-20-N23-00-38-12000 with a transmission rate of 38:1. The maximum output torque is about 5 Nm, depending on speed and usage duration. Also here you are able to choose between two versions:

1. high-end: RL-S-20-N23-00-38-12030 (with PRT-01-20)

2. standard: RL-S-20-N23-00-38-12000 (with a standard PRT-02-20-AL)

attached are CAD data and the current data sheets: RL-S-STEP+Data

All gears can be purchased with igus stepper motors, initiator kits, encoder kits or customized to be combined with your motor!
