When 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 certainly unevenly distributed over the planetary gears and the drive train operates less smoothly. Also, gear life can be shortened. These alignment changes require skills that are not normally available in the field.
Achieving a more substantial speed reduction ratio requires a smaller sun gear diameter (or an exceedingly large ring gear). This smaller sun equipment is usually integral using its shaft, which should be smaller aswell, 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 maximum reduction ratio. Planetary equipment trains provide high stiffness and low backlash (needed for accurate operation), plus actually load distribution (to acquire maximum torque). Some planetary variations combine external-tooth servo motor and gearbox pinion-and-gear models with planetary equipment sections to simplify set up and boost quickness. These hybrid gearheads are defined later.
A basic planetary gearhead has a few limitations regarding ease of installation, load capacity, and speed, all of which are related to sunlight gear.

As a rule, the designer usually obtains the optimum 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 loss in the motor, which makes it run more efficiently.

Servo motors deliver precise control of placement, velocity, and acceleration in the closed-loop systems of servomechanisms. Servo motors require a servo drive – this uses the opinions data to precisely control the position of the motors path and rotation distance.
Cone Drive’s stainless steel precision motion 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 digesting and pharmaceutical applications. The merchandise is designed and rated to IP69k offering maximum security against contaminant ingress in addition to leak free operation.
Servomotor selection usually begins with the designer seeking to reduce the engine size by utilizing a gearbox to lessen speed and increase torque. Speed reduction allows rapid acceleration and deceleration of huge loads using a small, less costly motor.
