Whenever 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 definitely unevenly distributed over the planetary gears and the drive teach operates less smoothly. Also, gear life can be shortened. These alignment changes require skills that aren’t normally available in the field.
Achieving a larger speed reduction ratio takes a smaller sun equipment diameter (or an exceedingly large ring gear). This smaller sun gear is usually integral with its shaft, which must be smaller as well, thereby reducing its strength and its torque or load capacity.

Several types of gear trains, including those with planetary gears, are commonly used to acquire this the best possible reduction ratio. Planetary equipment trains provide high stiffness and low backlash (necessary for accurate operation), plus even load distribution (to obtain optimum torque). Some planetary versions combine external-tooth pinion-and-gear sets with planetary equipment sections to simplify set up and boost acceleration. These hybrid gearheads are explained later.
A simple planetary gearhead has a few limitations regarding ease of installation, load capacity, and speed, which are related to sunlight gear.

As a rule, the designer usually obtains the the best possible speed decrease ratio by matching the inertia of the electric 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 servo motor and gearbox 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 designed for sterile manufacturing conditions. The product’s smooth surface and curved contour allows for easy cleaning and bacteria-free surfaces, perfect for meals processing and pharmaceutical applications. The merchandise is designed and rated to IP69k offering maximum safety against contaminant ingress along with leak free operation.
Servomotor selection usually starts with the designer seeking to reduce the engine size by utilizing a gearbox to lessen speed and enhance torque. Speed reduction allows rapid acceleration and deceleration of huge loads utilizing a small, less costly motor.
