When a conventional planetary gearhead is mounted to a electric motor, the sun gear must be aligned to pay for runout error of the servomotor shaft. Without proper alignment, load is definitely unevenly distributed over the planetary gears and the drive train operates less smoothly. Also, gear life could be shortened. These alignment adjustments require skills that are not normally obtainable in the field.
Achieving a more substantial speed reduction ratio requires a smaller sun gear diameter (or an exceedingly large ring equipment). This smaller sun gear is usually integral using its shaft, which should be smaller as well, thereby reducing its power and its torque or load capability.

Several types of gear trains, including people that have planetary gears, are commonly used to acquire this maximum reduction ratio. Planetary equipment trains offer high stiffness and low backlash (necessary for accurate procedure), plus actually load distribution (to acquire optimum torque). Some planetary versions combine external-tooth pinion-and-gear units with planetary gear sections to simplify installation and boost swiftness. These hybrid gearheads are defined later.
A basic 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 ideal speed reduction ratio by matching the inertia of the electric motor and gearbox with the inertia of the driven load. This inertia coordinating minimizes power reduction 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 exactly control the positioning of the motors direction and rotation distance.
Cone Drive’s stainless precision movement gearboxes are designed for sterile manufacturing conditions. The product’s smooth surface area and curved contour allows for easy cleaning and bacteria-free surfaces, ideal for food digesting and pharmaceutical applications. The merchandise is designed and rated to IP69k offering maximum protection against contaminant ingress in addition to leak free operation.
Servomotor selection usually begins with the designer seeking to reduce the electric motor size by using a gearbox to lessen speed and boost torque. Speed reduction allows fast acceleration and deceleration of huge loads using a small, less expensive motor.
