When a conventional planetary gearhead is mounted to a engine, 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 train operates less easily. Also, gear life could be shortened. These alignment modifications require skills that aren’t normally obtainable 
in the field.
Achieving a larger speed reduction ratio takes a smaller sun gear diameter (or an exceptionally large ring gear). This smaller sun gear is usually integral with its shaft, which must be smaller as well, thereby reducing its strength and its own torque or load capacity.
Several types of gear trains, including people that have planetary gears, are generally used to acquire this the best possible reduction ratio. Planetary equipment trains offer high stiffness and low backlash (needed for accurate operation), plus even load distribution (to acquire maximum torque). Some planetary variations combine external-tooth pinion-and-gear models with planetary equipment sections to simplify set up and boost speed. These hybrid gearheads are referred to later.
A basic planetary gearhead has several limitations regarding simple installation, load capacity, and speed, which are related to sunlight gear.
As a rule, the designer usually obtains the the best possible speed decrease ratio by matching the inertia of the motor and gearbox with the inertia of the driven load. This inertia coordinating minimizes power loss in the motor, making it run more efficiently.
Servo motors deliver precise control of placement, velocity, and acceleration in the closed-loop systems of servomechanisms. Servo motors need a servo drive – this uses the feedback data to specifically control the position of the motors path and rotation distance.
Cone Drive’s stainless steel precision movement gearboxes are designed for sterile manufacturing environments. The product’s smooth surface and curved contour permits easy cleaning and bacteria-free surfaces, perfect for meals processing and pharmaceutical applications. The merchandise is designed and servo motor and gearbox ranked to IP69k offering maximum security against contaminant ingress as well as leak free operation.
Servomotor selection usually begins with the designer wanting to reduce the engine size by utilizing a gearbox to reduce speed and increase torque. Speed decrease allows speedy acceleration and deceleration of large loads utilizing a small, less expensive motor.
