When 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 certainly unevenly distributed over the planetary gears and the drive train operates less smoothly. Also, gear life could be shortened. These alignment adjustments require skills that are not normally available in the field.
Achieving a larger 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 must be smaller as well, thereby reducing its strength and its torque or load capacity.

Various kinds gear trains, including those with planetary gears, are servo motor and gearbox Generally used to obtain this maximum reduction ratio. Planetary equipment trains provide high stiffness and low backlash (needed for accurate procedure), plus actually load distribution (to obtain optimum torque). Some planetary variations combine external-tooth pinion-and-gear models with planetary equipment sections to simplify installation and boost speed. These hybrid gearheads are referred to later.
A simple planetary gearhead has some limitations regarding simple installation, load capacity, and speed, all of which are related to the sun gear.

Generally, the designer usually obtains the optimum speed reduction ratio by matching the inertia of the engine and gearbox with the inertia of the driven load. This inertia complementing 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 steel precision motion gearboxes are created for sterile manufacturing conditions. The product’s smooth surface and curved contour permits easy cleaning and bacteria-free surfaces, ideal for meals processing and pharmaceutical applications. The product is designed and ranked to IP69k offering maximum safety against contaminant ingress and also leak free operation.
Servomotor selection usually begins with the designer seeking to reduce the motor size by using a gearbox to lessen speed and increase torque. Speed reduction allows fast acceleration and deceleration of large loads using a small, less costly motor.
