The new generation of strain wave gears convinces by its particularly compact design. The use of lubrication-free high-performance polymers makes the gear assembly very easy. In addition, the optimised use of tribo-polymers has improved smooth running, backlash and service life. Along the last axis of an articulated arm, linear robot or delta robot, the strain wave gear can be used before different gripper systems. Here, it performs the task of gripping objects that are not rotationally symmetrical and positioning them exactly.
The novel strain wave gear implements movements, for example on the robot axis 5, as well as many other durable and cost-effective automation applications. Due to their components, the igus strain wave gears are characterised by freedom from lubrication as well as friction and wear resistance. At the same time, the use of plastics enables an extremely compact design and cost-effective manufacture.
As a result of active research and further development of the strain wave gear, operating smoothness, backlash and service life of the latest generation have been optimised further by means of improvements in the technical design and in the selection of materials. The new strain wave gear can also be adapted to a stepper motor or other motor types. It is based on the Nema 17 installation size and was developed in such a way that a high ratio of 28:1 can be shown. This has been tested in our own test laboratory at a service life of 1 million cycles, a load of 1.5Nm and a speed of 6rpm. These development steps are already planned for the Nema 23 installation size.
