When a conventional planetary gearhead is mounted to a engine, the sun gear should be aligned to pay for runout error of the servomotor shaft. Without proper alignment, load is usually unevenly distributed over the planetary gears and the drive teach operates less efficiently. Also, gear life could be shortened. These alignment changes require skills that aren’t normally obtainable in the field.
Achieving a larger speed reduction ratio takes a smaller sun gear diameter (or an exceptionally large ring equipment). This smaller sun equipment is usually integral with its shaft, which should be smaller aswell, thereby reducing its strength and its torque or load capability.

Various kinds gear trains, including those with planetary gears, are commonly used to obtain this maximum reduction ratio. Planetary gear trains offer high stiffness and low backlash (necessary for accurate operation), plus actually load distribution (to obtain maximum torque). Some planetary variations combine external-tooth pinion-and-gear pieces with planetary gear sections to simplify installation and boost swiftness. These hybrid gearheads are explained later.
A simple planetary gearhead has some limitations regarding simple installation, load capacity, and speed, all of which are related to the sun gear.

Generally, the designer usually obtains the ideal speed decrease ratio by matching the inertia of the electric motor and gearbox with the inertia of the driven load. This inertia complementing minimizes power loss in the motor, making it run more efficiently.

Servo motors deliver precise control of placement, velocity, and acceleration in the closed-loop systems of servomechanisms. Servo motors require a servo drive – this uses the feedback data to specifically control the position of the motors path and rotation distance.
Cone Drive’s stainless steel precision movement gearboxes are created for sterile manufacturing environments. The product’s smooth surface and curved contour permits easy cleaning and bacteria-free surfaces, perfect for food processing and pharmaceutical applications. The product is designed and ranked to IP69k offering maximum security against contaminant servo motor and gearbox ingress in addition to leak free operation.
Servomotor selection usually begins with the designer seeking to reduce the engine size by utilizing a gearbox to reduce speed and boost torque. Speed decrease allows speedy acceleration and deceleration of huge loads utilizing a small, less expensive motor.
