Compact outline for zero-backlash gearheads
Nabtesco Precision has released its RGH series of compact gearheads through its newly appointed exclusive UK representative Servotechnic.
Servo actuator handles large loads
The hollow shaft PowerHub is a compact servo actuator with a centre through hole and the precision and repeatability of a zero backlash gear.
The two degrees of freedom in movement can be actuated independently or concurrently.
These devices can be run using a standard two-axis stepper motor driver.
Performance can be enhanced using chopper and/or micro stepping drives.
The actuator is based on a unique patent pending design and incorporates proven motor technology from Haydon Switch.
This unit simplifies bulky and complex mechanisms.
The new design has a compact package length, which maximizes the linear stroke to unit length ratio.
Using high quality stepper motors the unit is capable of delivering up to 222N of thrust and 127mNm of torque.
The rotary portion is a 1.8-degree step angle, and is able to be micro stepped for finer resolutions.
The linear portion uses the same high performance thermoplastic nut material as Haydon Switch's high efficiency long life linear actuators.
No maintenance is required and the entire actuator is designed for long service life.
It is available in a wide variety of resolutions - from 3 to 49um per step and delivers linear speeds exceeding 76mm/s.
The linear/ rotary unit allows for simplified system design and a reduction in the number of components.
It is ideal for use in tight fitting applications requiring precise two degree of freedom, controllable motion, pick and place equipment, robotics, and a wide array of instrumentation.
