Wave reducers
Wave reducers are composed
- Wave generator
The wave generator consists of a flexible bearing and an elliptical cam. The wave generator is usually installed at the input of the gearbox, the inner ring of the flexible bearing is fixed on the cam, and the outer ring is elastically deformed into a ball ellipse.
- Flexible wheel
A flexible thin-walled elastic part with an outer ring, usually mounted on the output of the gearbox.
- Solid wheel
A solid ring with an inner ring usually has two more teeth than a flexible ring and is usually attached to the gear housing.
The flexible gear and elastic bearing take on an elliptical shape with the wave generator inserted.
A flexible gear and an internal gear are engaged at both ends of the long axis of the ellipse in a stable manner.
With a fixed internal gear, when the wave generator rotates clockwise, the flexible gear (output) rotates counterclockwise. Its rotation speed is determined by the difference in the number of teeth between two gears.
The main differences of the wave gearbox
- Large gear ratio for a single-stage model: up to 320:1
- A large number of teeth that are in simultaneous engagement
- High accuracy
- No small gear ratios (less than 30:1)
- Simple design
- High reliability
- Hollow shaft
- The torsional stiffness
- Short axial length
Practical advantages of wave reducers
The distinctive characteristics of wave reducers act as advantages in a number of industries that are currently highly developed. Examples include robotics (classic industrial robots, collaborative robots, and humanoid robots) and medical technology (surgical robots, medical scanning units, and exo skeletons). The short length along the axis, the possibility of obtaining high torque in compact dimensions, as well as the hollow shaft allow compact dimensions of all parts of the robot, and the high precision of the gearboxes allow good accuracy of the entire robot.
In other industries, where the finished products must work in aggressive environments (for example, vacuum, radioactive radiation, especially high or very low temperatures), wave reducers are often used. Here, a high specific torque is required, which allows for a compact design, the possibility of simple transfer of rotation in an aggressive environment without additional seals and good reliability indicators due to the simple design.
