Spinea TS50 and DS50 Range
Date: 12 May 2009
Compact zero-backlash gearbox and servo actuator range punches well above its size with 18 Nm torque rating in 50 mm housing
New compact gearbox actuator extends Spinea
TwinSpin range to cover space restricted precision positioning for
high torque loads.
A new range of ultra-compact high-torque gearboxes and servomotor
driven rotary positioning actuators, based upon SPINEA's
TwinSpin® 'bearing reducer' technology has been launched
by motion control specialists Heason Technology.
The TS50 gearbox and DS50 servo actuator are both packaged in
nominal 50 mm square housings and, complete with heavy duty
radial/axial output bearings, feature an incredible 18 Nm rated
torque output with a five times overload capacity for short term
emergency conditions. With smooth backlash-free performance suited
to high precision/heavy load positioning, the new miniature gearbox
and actuator will satisfy demanding space restricted and high
torque applications across robotics and automation.
The TwinSpin uses a patented trochoidal gear reduction principle,
based on two eccentrically rotating planetary gears that mesh via
precision needle rollers in an outer gear ring. The input shaft
rotates the eccentric action of the planetary gearing, causing the
outer ring to rotate in the same direction. With almost 50%
simultaneous gear meshing and with the input to output reduction
determined by the ratio between planetary and ring gear teeth, the
TwinSpin is able to efficiently transmit very high torque with
backlash-free performance.
In addition, due to such a high contact surface area and an
integrally robust power transmission and bearing system, the
TwinSpin bearing reducer can withstand up to five times overload
torque under emergency stall conditions. Furthermore, the design
boasts a very low input inertia and friction rating allowing a fast
servo system response with noise and vibration levels that are also
suited to sensitive hi resolution positioning.
For the new miniature TS50 gearbox, a standard internal 6 mm
diameter shaft with a keyway slot provides the input interface and
the output is handled by a flange opposite to the mounting
face.
With a fixed 63:1 reduction ratio and overall length within 41 mm,
it is possible to offer a variety of different input to output
mechanical configurations and alternate internal bearing systems to
suit increased load handling, reduced friction, larger ambient
temperature range and improved precision versions. The protection
class for the standard product is IP64.
When built into the DS50 compact servo actuator, the gearbox is
mounted to high performance AC servomotor with integral resolver
feedback. The mechanical interface from the output shaft to the
customers load may be customised to suit requirements. Brake
options are available and motors may be fitted with flying lead or
connectors.
Alternative position feedback options including external load
mounted rotary or linear encoder systems are available from Heason
Technology who is also able to provide a wide range of drives and
motion controls to complete the application.
