When a conventional planetary gearhead is mounted to a motor, the sun gear must be aligned to pay for runout error of the servomotor shaft. Without proper alignment, load is unevenly distributed over the planetary gears and the drive train operates less smoothly. Also, gear life can be shortened. These alignment modifications require skills that aren’t normally available in the field.
Achieving a more substantial speed reduction ratio takes a smaller sun gear diameter (or an exceptionally large ring gear). This smaller sun equipment is usually integral using its shaft, which should be smaller aswell, thereby reducing its power and its own torque or load capacity.

Several types of gear trains, including those with planetary gears, are generally used to acquire this ideal reduction ratio. Planetary gear trains offer high stiffness and low backlash (necessary for accurate procedure), plus even load distribution (to obtain optimum torque). Some planetary versions combine external-tooth pinion-and-gear units with planetary equipment sections to simplify installation and boost quickness. These hybrid gearheads are described later.
A basic planetary gearhead has some limitations regarding ease of installation, load capacity, and speed, which are related to sunlight gear.

As a rule, the designer usually obtains the optimum speed reduction ratio by matching the inertia of the motor and gearbox with the inertia of the driven load. This inertia matching 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 exactly control the positioning of the motors direction 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 allows for easy cleaning and bacteria-free surfaces, ideal for food processing and pharmaceutical applications. The product is designed and ranked to IP69k providing maximum protection against contaminant ingress and also leak free operation.
Servomotor selection usually begins with the designer wanting to reduce the engine size by utilizing a gearbox to reduce speed and enhance torque. Speed decrease allows fast acceleration and deceleration of large loads utilizing a small, less expensive motor.
