Industrial Robot Helical Gear Circular-Arc Gear Reducing Noise And
Vibration For Ovearall Performance
Helical gears are a type of cylindrical gear that have angled
teeth. In industrial robots, helical gears are used for various
applications that require high torque transmission and smooth
operation. Here's how helical gears are used in industrial robots:
Power Transmission: Helical gears are commonly used for power
transmission in industrial robots. They provide a more gradual and
continuous tooth engagement compared to spur gears, resulting in
smoother and quieter operation. Helical gears are effective in
transmitting rotational motion and torque from the robot's motors
to the various components and actuators.
High Torque Applications: Industrial robots often require high
torque transmission capabilities to handle heavy loads or perform
tasks that require significant force. Helical gears are well-suited
for such applications due to their larger contact area and
increased tooth engagement compared to spur gears. The angled teeth
of helical gears distribute the load over a larger area, allowing
for higher torque transmission.
Improved Load Distribution: The helical tooth profile of helical
gears helps distribute the load more evenly along the teeth,
reducing stress concentration and enhancing the gear's
load-carrying capacity. This feature is beneficial in industrial
robots where precise and reliable motion control is crucial.
Noise and Vibration Reduction: Helical gears offer quieter
operation compared to spur gears due to their angled teeth. The
gradual engagement and overlapping of teeth help minimize noise and
vibration, resulting in smoother and more reliable robot movements.
High Precision Positioning: Helical gears contribute to high
precision positioning in industrial robots. The continuous
engagement of the helical teeth allows for fine adjustments and
accurate control of the robot's joints and movements. This
precision is essential for tasks that require accurate positioning
and repeatability, such as assembly operations or machining
processes.
Backlash Reduction: Backlash, which is the play or clearance
between the teeth of gears, can negatively affect the accuracy and
responsiveness of robot movements. Helical gears can help reduce
backlash due to their continuous contact and meshing, resulting in
improved motion control and repeatability.
It's worth noting that while helical gears offer advantages, they
also introduce axial thrust due to their helical tooth profile.
This axial thrust needs to be properly managed in the design and
construction of the robot's mechanisms.
Overall, helical gears are commonly used in industrial robots to
achieve high torque transmission, precise motion control, reduced
noise and vibration, and improved overall performance.
