Whenever a conventional planetary gearhead is mounted to a electric motor, 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 train operates less efficiently. 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 requires a smaller sun gear diameter (or an exceedingly large ring equipment). This smaller sun gear is usually integral with its shaft, which should be smaller as well, thereby reducing its power and its torque or load capacity.

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

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

Servo motors deliver precise control of position, velocity, and acceleration in the closed-loop systems of servomechanisms. Servo motors need a servo drive – this uses the opinions data to specifically control the servo motor and gearbox position of the motors path and rotation distance.
Cone Drive’s stainless precision movement gearboxes are designed for sterile manufacturing conditions. The product’s smooth surface and curved contour allows for easy cleaning and bacteria-free surfaces, ideal for food digesting and pharmaceutical applications. The product is designed and ranked to IP69k providing maximum security against contaminant ingress in addition to leak free operation.
Servomotor selection usually starts with the designer wanting to reduce the electric motor size by using a gearbox to lessen speed and increase torque. Speed reduction allows quick acceleration and deceleration of huge loads utilizing a small, less expensive motor.
