What Is Leaderdrive Harmonic Drive

Leaderdrive harmonic drive speed reducers utilize a unique operating principle, the gear consists of only 3 basic parts (Wave Generator, Flexspline, and Circular Spline). It provides excellent features not found in other speed reducers. The Leaderdrive harmonic drive speed reducer wave generator is a thin raced ball bearing fitted onto an elliptical hub. This serves as a high efficiency torques converter and is generally mounted onto the input or motor shaft. The Leaderdrive harmonic drive speed reducer Flexspline is a non-rigid, thin cylindrical cup with external teeth on the open end of the cup. The Flexspline fits over the wave generator and takes on its elliptical shape. The Flexspline is generally used as the output of the gear. The Leaderdrive harmonic drive speed reducer circular spline is a rigid ring with internal teeth. It engages the teeth of the Flexspline across the major axis of the wave generator ellipse. The circular spline has two more teeth than the Flexspline and is generally mounted onto a housing.

Operating Principle of Leaderdrive Harmonic Drive

The Leaderdrive harmonic drive speed reducer flexspline is slightly smaller in diameter than the Circular Spline and usually has two fewer teeth than the wave generator. The elliptical shape of the wave generator causes the teeth of the Flexspline to engage the Circular Spline at two opposite regions across the major axis of the ellipse.

As the Leaderdrive harmonic drive speed reducer wave generator rotates the teeth of the Flexspline engage with the Circular Spline at the major axis. For every 180-degree clockwise movement of the Wave Generator the Flexspline rotates counter-clockwise by one tooth in relation to the Circular Spline.

Each complete clockwise rotation of the wave generator results in the Leaderdrive harmonic drive speed reducer Felxspline moving counter-clockwise by two teeth from its original position relative to the Circular Spline.

Leaderdrive Harmonic Drive - A Guide to Choosing Gears for Robotics

Although there are now a variety of electrical configurations to choose from, this hasn't always been the case. Before widespread electrical innovation in induction motor technology and the advent of variable speed drives (VSDs), controlling the output speed of a system was achieved through the use of gears.This means that the final output speed of a typical squirrel-cage motor running at 1440rpm can be reduced as required by varying the gear reduction ratio. This increases flexibility by allowing the same motor to be used for different speed applications without a VSD.It is now of course possible to control the speed of a motor using VSDs however the drive cannot replace the gears other key benefits, torque multiplication and inertia matching, allowing a relatively small, low power, motor to move and accurately control a large load, hence reducing running costs and general machine weight and size.

For anyone using this basic gear type and the closely related helical gear there are a few considerations. Generally these gears have significant backlash and although they can be fitted with backlash compensation, this accuracy is not maintained throughout the gear's life without adjustment. As well as this, spur gears can be noisy at high speed, helical gearing less so. Also, while they have the ability to be variably configured they can occupy a large footprint especially in high ratios, due in part to each individual gear shaft needing to be supported in its own bearings. A Bevel gear can be considered in the same family as a spur/helical gear and can also be straight or helical cut. Many of the considerations above apply, although the right angled nature of this gear can help in applications where space is at a premium.

So called, due to its earthworm like movement, the worm drive consists of two parts, the screw shaped worm gear and the larger spur-shaped worm wheel. Meshed perpendicular to the axis of rotation, the worm gear offers a compact solution and a large single-stage gear reduction can be achieved, however the larger ratios suffer from low efficiency. The design of a worm gear means that a large hollowshaft can be bored into the central cylinder of the worm wheel, making it convenient to pass through cables and services. With a few modifications, this gear type can also offer relatively good precision. By increasing the pressure on the surfaces in contact, backlash, the transverse movement apparent in a gearing system, can be reduced. However, this does increase wear on the teeth, reducing efficiency and meaning in-life adjustment is often necessary to maintain the accuracy of the gearbox.

Moving up to the next category we have epicyclic gears. More commonly known as planetary gears they are mounted in such a way that a numbers of gears, typically three to five, rotate like planets around a central sun gear, surrounded by an outer annular ring gear. Planetary gears provide a high power density, over 95% efficiency and, as a result of their design, are very compact. Accuracy can be high, with backlash achievable down to 1 arcmin. By combining several stages of gearing, high reduction ratios can be achieved with the maximum single stage ratio typically being 10:1. Planetary gears are generally more expensive than helical gears and can require more maintenance owing to a higher part count.

Routine Maintenance And Inspection Of Leaderdrive Harmonic Drive

Checking the harmonic grease
Turn off the power to prevent electric shock! Wait for the reducer to cool! Open the oil drain plug and take the oil sample. Check the viscosity index of the oil. If the oil is turbid, it is recommended to replace it as soon as possible. Check the oil level of the reducer with oil level screw plug, whether it is qualified to install the oil level screw plug.

Check the oil level of the harmonic reducer
Turn off the power to prevent electric shock! Wait for the reducer to cool! Remove the oil level plug to check if the oil is full. Install the oil level plug.

Harmonic reducer oil replacement
After the cooling, the viscosity of the oil increases and the oil is difficult to drain. The speed reducer should change the oil at the operating temperature. Turn off the power to prevent electric shock! Wait for the reducer to cool down without burning danger! Note: The gearbox should remain warm when changing oil. Place an oil pan under the oil drain plug. Open the oil level plug, ventilator and drain plug. Remove all oil. Install the oil drain plug. Inject new oil of the same grade. The amount of oil should be the same as the installation location. Check the oil level at the oil level plug. Tighten the oil level plug and ventilator.
