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 unevenly distributed over the planetary gears and the drive train operates less efficiently. Also, gear life could be shortened. These alignment adjustments require skills that are not normally available in the field.
Achieving a more substantial speed reduction ratio requires a smaller sun equipment diameter (or an exceedingly large ring gear). This smaller sun equipment is usually integral with its shaft, which must be smaller as well, thereby 
reducing its power and its torque or load capacity.
Various kinds gear trains, including those with planetary gears, are generally used to acquire this the best reduction ratio. Planetary equipment trains provide high stiffness and low backlash (necessary for accurate operation), plus also load distribution (to obtain maximum torque). Some planetary variations combine external-tooth pinion-and-gear pieces with planetary gear sections to simplify set up and boost speed. These hybrid gearheads are referred to later.
A basic planetary gearhead has a few limitations regarding simple installation, load capacity, and speed, all of which are related to sunlight gear.
As a rule, the designer usually obtains the maximum speed reduction ratio by matching the inertia of the electric motor and gearbox with the inertia of the driven load. This inertia complementing minimizes power reduction in the motor, which makes 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 position of the motors direction and rotation distance.
Cone Drive’s stainless precision motion gearboxes are created for sterile manufacturing conditions. The product’s smooth surface area and curved contour permits easy cleaning and bacteria-free surfaces, perfect for food processing and pharmaceutical applications. The merchandise is designed and rated to IP69k providing 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 increase torque. Speed decrease allows fast acceleration and deceleration of huge loads utilizing a small, less expensive motor.
