Whenever a conventional planetary gearhead is mounted to a motor, the sun gear must be aligned to compensate 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 easily. Also, gear life can be shortened. These alignment modifications require skills that aren’t normally available in the field.
Achieving a larger speed reduction ratio takes a smaller sun gear 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 torque or load capacity.

Several types of gear trains, including those with planetary gears, are generally used to acquire this the best possible reduction ratio. Planetary gear trains provide high stiffness and low backlash (needed for accurate procedure), plus even load distribution (to obtain optimum torque). Some planetary variations combine external-tooth pinion-and-gear models with planetary gear sections to simplify installation and boost velocity. These hybrid gearheads are described later.
A basic planetary gearhead has some limitations regarding simple installation, load capacity, and speed, all of which are related to sunlight gear.

Generally, the designer usually obtains the the best speed decrease ratio by matching the inertia of the engine and gearbox with the inertia of the driven load. This inertia matching minimizes power loss 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 need a servo drive – this uses the feedback data to precisely control the position of the motors direction and rotation distance.
Cone Drive’s stainless precision movement gearboxes are made for sterile manufacturing conditions. The product’s smooth surface area and curved contour allows for easy cleaning and bacteria-free surfaces, ideal for meals processing and pharmaceutical applications. The servo reducer merchandise is designed and ranked to IP69k offering maximum security 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 enhance torque. Speed decrease allows rapid acceleration and deceleration of huge loads utilizing a small, less costly motor.
