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 unevenly distributed over the planetary gears and the drive teach operates less smoothly. Also, gear life can be shortened. These alignment adjustments require skills that are not normally available in the field.
Achieving a more substantial speed reduction ratio requires a smaller sun equipment diameter (or an exceedingly large ring equipment). This smaller sun equipment is usually integral with its shaft, which must 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 generally used to acquire this optimum reduction ratio. Planetary gear trains offer high stiffness and low backlash (necessary for accurate procedure), plus even load distribution (to acquire maximum torque). Some planetary variations combine external-tooth pinion-and-gear sets with planetary equipment sections to simplify set up and boost speed. These hybrid gearheads are explained later.
A basic planetary gearhead has several limitations regarding simple installation, load capacity, and speed, which are related to sunlight gear.

Generally, the designer usually obtains the the best speed servo motor and gearbox decrease ratio by matching the inertia of the electric motor and gearbox with the inertia of the driven load. This inertia complementing minimizes power reduction 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 specifically control the positioning of the motors direction and rotation distance.
Cone Drive’s stainless steel precision motion gearboxes are created for sterile manufacturing environments. The product’s smooth surface and curved contour allows for easy cleaning and bacteria-free surfaces, perfect for food processing and pharmaceutical applications. The merchandise is designed and ranked to IP69k providing maximum safety against contaminant ingress along with leak free operation.
Servomotor selection usually begins with the designer wanting to reduce the motor size by utilizing a gearbox to reduce speed and boost torque. Speed reduction allows quick acceleration and deceleration of large loads using a small, less costly motor.
