DieQua's New FlexSpline Robotic Gear Reducers
SPONSORED BY: ![]()
DieQua's SymphoDrive speed reducer technology reduces the speed of a motor’s input shaft by a predetermined ratio, matched to the application and the type of equipment used. These high-precision devices deliver relatively high reduction ratios, all available in 5 frame sizes from 14 - 32mm. Speed reducers are essential for precise motion control in sophisticated systems such as robotics, military/defense equipment, and satellite antennas.

Overview
The white paper discusses the SymphoDrive speed reducer technology developed by DieQua, focusing on its innovative design and applications in high-performance motion control systems. SymphoDrive reducers utilize a unique Flex Spline/Strain Wave gearing mechanism, which consists of three main components: the input shaft and Wave Generator, the Flexible Steel Wave Generator, and the Rigid Circular Ring Gear. This configuration allows for high reduction ratios ranging from 50:1 to 120:1, essential for precise motion control in various applications, including robotics, military equipment, and satellite antennas.
A key feature of SymphoDrive reducers is their zero backlash capability, which is crucial for applications requiring precise positioning. Backlash can lead to uncontrolled movements, particularly in scenarios where loads transition over critical points, such as a robotic arm moving a load. The zero backlash design ensures predictable and controlled motion, enhancing the performance of robotic systems.
Motor integration with SymphoDrive reducers is facilitated through either a quill input for keyed straight shaft motors or a hollow bore shaft with a timing pulley connection. This flexibility allows for compact integration and the ability to route application cabling, pneumatic tubing, and fiber optics through the center of the reducer, optimizing space and design.
The white paper also highlights the compact nature of SymphoDrive housings, which are designed to minimize the number of components while maximizing performance. With five available frame sizes, ranging from 14 mm to 32 mm, these reducers conform to the ISO 9409 Robot Output component standard, making them compatible with various robotic applications.
Additionally, the paper addresses the compatibility of SymphoDrive reducers with other Flex Spline or StrainWave reducers in the market, offering options for both enclosed housing installations and component sets for integration into existing configurations.
In summary, the SymphoDrive speed reducer technology represents a significant advancement in motion control, providing ultra-precision, high reliability, and long service life. Its innovative design and zero backlash feature make it an ideal choice for demanding applications in robotics and automation, positioning it as a leading solution in the field of motion control gear reducers.
