Whenever a conventional planetary gearhead is mounted to a motor, the sun gear should 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 easily. Also, gear life can be shortened. These alignment adjustments require skills that aren’t normally servo reducer available in the field.
Achieving a more substantial 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 aswell, thereby reducing its power and its torque or load capability.

Various kinds gear trains, including people that have planetary gears, are commonly used to obtain this ideal reduction ratio. Planetary gear trains offer high stiffness and low backlash (needed for accurate procedure), plus even load distribution (to obtain optimum torque). Some planetary variations combine external-tooth pinion-and-gear units with planetary equipment 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, all of which are related to the sun gear.

As a rule, the designer usually obtains the optimum speed reduction ratio by matching the inertia of the motor and gearbox with the inertia of the driven load. This inertia matching 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 need a servo drive – this uses the opinions data to exactly control the position of the motors path and rotation distance.
Cone Drive’s stainless steel precision motion gearboxes are made for sterile manufacturing environments. The product’s smooth surface area and curved contour allows for easy cleaning and bacteria-free surfaces, ideal for food digesting and pharmaceutical applications. The merchandise is designed and ranked to IP69k providing maximum security against contaminant ingress and also leak free operation.
Servomotor selection usually starts with the designer seeking to reduce the motor size by using a gearbox to reduce speed and boost torque. Speed decrease allows quick acceleration and deceleration of large loads using a small, less expensive motor.
