Harmonic Drive UK, the precision gearing specialists, has released a new series of robotic gears for highly dynamic applications, such as robotic axes.
Harmonic told RoboPro that the SHG Series offers high resistance to shock loads, due to its 30% increase in collision torque, compared to previous models.
The company added that the higher torque values ensures increased dynamics and reduces cycle time for positioning tasks. When this is paired with the components’ increased collision torque, it allows industrial robots to provide precise movement, even when lifting and moving heavy loads.
The SHG Series Units are available in ten sizes, with gear ratios of 50, 80, 100, 120 and 160, offering repeatable peak torques from 23 to 3419 Nm.
“Robots are a staple of industry, they permeate every process and are indispensable in achieving efficiency and high levels of production. The SHG Series was made with industrial robots in mind and the three versions available offer a high degree of flexibility to design engineers,” explained Graham Mackrell, managing director of Harmonic Drive UK.
“While their compact design and high torque density means there is no compromise in size versus use. The SHG Unit Series comes in SHG-2UH, 2SH and 2SO versions.
“The 2UH has a mounted and fully sealed hollow shaft, through which to feed supply line, shafts or cables. in contrast the 2SH and 2SO are simpler units, composed of the components and the output bearing, reducing maintenance. The hollow shaft is used directly as the rotor for the drive motor reducing the amount of complex parts. As a result, SHG Unit Series are ready for both simple and complex uses.”
