Whenever a conventional planetary gearhead is mounted to a engine, the sun gear must be aligned to compensate for runout error of the servomotor shaft. Without proper alignment, load can be unevenly distributed over the planetary gears and the drive teach operates less efficiently. Also, gear life can be shortened. These alignment adjustments require skills that are not 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 with its shaft, which must be smaller as well, thereby reducing its strength and its torque or load capability.

Several types of gear trains, including those with planetary gears, are commonly used to acquire this ideal reduction ratio. Planetary gear trains offer high stiffness and low backlash (needed for accurate procedure), plus actually load distribution (to acquire maximum torque). Some planetary variations combine external-tooth pinion-and-gear models with planetary equipment sections to simplify installation and boost swiftness. These hybrid gearheads are referred to later.
A basic planetary gearhead has a few limitations regarding simple installation, load capacity, and speed, 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 coordinating 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 direction 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 meals processing and pharmaceutical applications. The product is designed and rated to IP69k offering maximum protection against servo motor and gearbox contaminant ingress in addition to leak free operation.
Servomotor selection usually starts with the designer wanting to reduce the motor size by using a gearbox to lessen speed and enhance torque. Speed decrease allows rapid acceleration and deceleration of large loads using a small, less costly motor.
