Differences in Output Speed Between Spur Gear Slew Drives and Slewing Drives

Output speed is one of the most intuitive differences between spur gear slew drives and slewing drives. Thanks to the structural characteristics of their gear meshing, spur gear slew drives offer superior high-speed transmission capabilities, with output speeds significantly higher than those of slewing drives.

From the perspective of structural principles, the tooth direction of spur gears is parallel to the gear axis. This results in low transmission resistance during meshing and high power transmission efficiency, enabling stable power output even at relatively high input speeds. Spur gear slew drives are therefore suitable for transmission scenarios requiring high-speed operation.

In contrast, slewing drives typically adopt a combined structure such as worm gears and planetary gears. Their design prioritizes low-speed, high-torque power output, featuring a larger gear reduction ratio in meshing. Consequently, their output speeds are generally low, making them unable to meet high-speed transmission requirements. For instance, in high-speed conveying mechanisms of automated production lines, spur gear slew drives can achieve stable output at several hundred revolutions per minute, a speed level that slewing drives cannot match in such scenarios.
