The CPU Units of Harmonic Drive They impress with their freedom of movement, have a very good concentricity, a very high repeatability and transmission accuracy and industry-leading values for the torque density. With the new CPU-plus series, the existing advantages could be further improved: The new, environmentally friendly and magenta-colored lubricant "Flexolub A1" increases performance and energy consumption is reduced. Friction and wear are minimized, efficiency and operating temperature are increased.
With an operating temperature range of -40 ° to + 120 ° C, the CPU-plus Unit can also be used in mobile applications without limitation in maximum torque. An increase in the average speeds of up to 270% for the hollow shaft variants makes it possible to increase the machine cycle times without integrating additional cooling systems. Especially with cold starts, the CPU-plus series leads to an improved energy balance. For example, with the size 20 with the reduction 100 and a temperature of 0 ° C, a considerably improved load-free starting torque of 0,4 Nm could be measured.
With a nominal torque of 40 Nm and a drive speed of 3500 min-1 The efficiency could be increased by 15% so that smaller units and motors can be used.
