Whenever a conventional planetary gearhead is mounted to a engine, the sun gear should be aligned to compensate for runout error of the servomotor shaft. Without proper alignment, load can be unevenly distributed over the planetary gears and the drive teach operates less easily. Also, gear life can be shortened. These alignment modifications 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 gear is usually integral using its shaft, which should be smaller aswell, thereby reducing its strength and its own torque or load capability.

Several types of gear trains, including people that have planetary gears, are generally used to obtain this maximum reduction ratio. Planetary gear trains offer high stiffness and low backlash (needed for accurate procedure), plus even load distribution (to acquire optimum torque). Some planetary versions combine external-tooth pinion-and-gear units with planetary equipment sections to simplify installation and boost rate. These hybrid gearheads are described later.
A simple planetary gearhead has several limitations regarding ease of installation, load capacity, and speed, which are related to the sun gear.

Generally, the designer usually obtains the the best speed decrease ratio by matching the inertia of the motor and gearbox with the inertia of the driven load. This inertia coordinating 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 need a servo drive – this uses the feedback data to precisely control the positioning of the motors path and rotation distance.
Cone Drive’s stainless steel precision motion gearboxes are designed for sterile manufacturing environments. The product’s smooth surface and curved contour allows for easy cleaning and bacteria-free surfaces, ideal for meals processing and pharmaceutical applications. The product is designed and ranked to IP69k offering maximum protection against contaminant servo reducer ingress along with leak free operation.
Servomotor selection usually begins with the designer seeking to reduce the motor size by using a gearbox to reduce speed and boost torque. Speed reduction allows rapid acceleration and deceleration of large loads using a small, less costly motor.
