Whenever a conventional planetary gearhead is mounted to a engine, the sun gear must be aligned to pay 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 easily. 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 requires a smaller sun equipment diameter (or an exceptionally large ring gear). This smaller sun equipment is usually integral with its shaft, which should be smaller aswell, thereby reducing its power and its own 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 gear trains provide high stiffness and low backlash (needed for accurate operation), plus even load distribution (to acquire maximum torque). Some planetary versions combine external-tooth pinion-and-gear sets with planetary equipment sections to simplify set up and boost quickness. These hybrid gearheads are explained later.
A simple planetary gearhead has several limitations regarding simple installation, load capacity, and speed, which are related to the sun gear.
As a rule, the designer usually obtains the the best possible speed decrease ratio by matching the inertia of the motor and gearbox with the inertia of the driven load. This inertia complementing minimizes power loss 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 positioning of the motors path and rotation distance.
Cone Drive’s stainless precision movement gearboxes are designed for sterile manufacturing environments. The product’s smooth surface and curved contour allows for easy cleaning and bacteria-free surfaces, perfect for food digesting and pharmaceutical applications. The merchandise is designed and rated to IP69k providing maximum safety against contaminant ingress in addition to leak free operation.
Servomotor selection usually starts with the designer seeking to reduce the engine 
size by using a gearbox to reduce speed and boost torque. Speed decrease allows quick acceleration and deceleration of large loads using a small, less costly motor.
