When a conventional planetary gearhead is mounted to a engine, the sun gear must be aligned to compensate for runout error of the servomotor shaft. Without proper alignment, load is usually unevenly distributed over the planetary gears and the drive teach operates less smoothly. Also, gear life can be shortened. These alignment modifications require skills that are not normally obtainable in the field.
Achieving a more substantial speed reduction ratio takes a smaller sun equipment diameter (or an exceptionally large ring equipment). This smaller sun equipment is usually integral using its shaft, which must 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 generally used to obtain this ideal reduction ratio. Planetary gear trains offer high stiffness and low backlash (necessary for accurate procedure), plus actually load distribution (to obtain maximum torque). Some planetary versions combine external-tooth pinion-and-gear sets with planetary gear sections to simplify set up and boost quickness. These hybrid gearheads are described later.
A simple planetary gearhead has several limitations regarding simple installation, load capacity, and speed, all of which are related to the sun gear.
As a rule, the designer usually obtains the ideal speed decrease ratio by matching the inertia of the motor and gearbox with the inertia of the driven load. This inertia matching 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 require a servo drive – this uses the opinions data to exactly control the positioning of the motors path and rotation distance.
Cone Drive’s stainless precision motion gearboxes are designed for sterile manufacturing environments. The product’s smooth surface area and curved contour permits easy cleaning and bacteria-free surfaces, perfect for meals digesting and pharmaceutical applications. The merchandise is designed and rated to IP69k offering maximum safety against contaminant ingress as well as leak free operation.
Servomotor selection usually starts with the designer wanting to reduce the engine size by utilizing a gearbox to lessen speed and boost torque. Speed decrease allows rapid acceleration and deceleration of huge loads utilizing a 
small, less costly motor.
