Whenever a conventional planetary gearhead is mounted to a engine, the sun gear should be aligned to pay 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 gear is usually integral using its shaft, which must be smaller as well, thereby reducing its power and its torque or load capability.

Several types of gear trains, including people that have planetary gears, are generally used to obtain this maximum reduction ratio. Planetary equipment trains offer high stiffness and low backlash (needed for accurate procedure), plus even load distribution (to acquire optimum torque). Some planetary versions combine external-tooth pinion-and-gear sets with planetary gear sections to simplify set up and boost rate. These hybrid gearheads are defined later.
A basic planetary gearhead has several limitations regarding ease of installation, load capacity, and speed, which are related to the sun gear.

Generally, 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 feedback data to specifically control the position of the motors path and rotation distance.
Cone Drive’s stainless steel precision motion gearboxes are designed for sterile manufacturing environments. The product’s smooth surface and curved contour allows for easy cleaning and bacteria-free surfaces, ideal for food processing and pharmaceutical applications. The product is designed and ranked to IP69k offering maximum security against contaminant ingress and also leak free operation.
Servomotor selection usually starts with the designer wanting to reduce the electric motor size by using a gearbox to reduce speed and boost torque. Speed decrease allows speedy acceleration and deceleration of large loads using a small, less costly motor.
