When a conventional planetary gearhead is mounted to a engine, the sun gear must be aligned to pay for runout error of the servomotor shaft. Without proper alignment, load is usually unevenly distributed over the planetary gears and the drive teach operates less efficiently. Also, gear life could be shortened. These alignment changes require skills that aren’t normally obtainable in the field.
Achieving a larger speed reduction ratio takes a smaller sun equipment diameter (or an exceedingly large ring equipment). This smaller sun gear is usually integral with its shaft, which should be smaller aswell, thereby reducing its power and its own torque or load capacity.

Various kinds gear trains, including people that have planetary gears, are commonly used to acquire this the best possible reduction ratio. Planetary gear trains provide high stiffness and low backlash (needed for accurate operation), plus even load distribution (to obtain optimum torque). Some planetary variations combine external-tooth pinion-and-gear sets with planetary gear sections to simplify installation and boost swiftness. These hybrid gearheads are explained later.
A simple planetary gearhead has some limitations regarding simple installation, load capacity, and speed, which are related to the sun gear.

Generally, the designer usually obtains the the best possible 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, which makes it run more efficiently.

Servo motors deliver precise control of placement, servo reducer 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 movement gearboxes are designed for sterile manufacturing conditions. The product’s smooth surface area and curved contour permits easy cleaning and bacteria-free surfaces, perfect for meals digesting and pharmaceutical applications. The merchandise is designed and ranked to IP69k providing maximum safety against contaminant ingress and also leak free operation.
Servomotor selection usually begins with the designer wanting to reduce the electric motor size by using a gearbox to reduce speed and enhance torque. Speed reduction allows rapid acceleration and deceleration of large loads using a small, less costly motor.
