Whenever 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 certainly unevenly distributed over the planetary gears and the drive train operates less efficiently. Also, gear life can be shortened. These alignment changes require skills that aren’t normally available in the field.
Achieving a more substantial speed reduction ratio requires a smaller sun equipment diameter (or an exceptionally large ring equipment). This smaller sun equipment is usually integral with its shaft, which must be smaller as well, thereby reducing its power and its own torque or load capability.
Several 
types of gear trains, including people that have planetary gears, are commonly used to obtain this optimum reduction ratio. Planetary gear trains offer high stiffness and low backlash (necessary for accurate operation), plus even load distribution (to obtain optimum torque). Some planetary versions combine external-tooth pinion-and-gear sets with planetary gear sections to simplify set up and boost speed. These hybrid gearheads are explained later.
A basic planetary gearhead has some limitations regarding simple installation, load capacity, and speed, which are related to sunlight gear.
As a rule, 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 matching 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 opinions data to precisely control the position of the motors path and rotation distance.
Cone Drive’s stainless precision motion gearboxes are created for sterile manufacturing conditions. The product’s smooth surface area and curved contour permits easy cleaning and bacteria-free surfaces, perfect for food processing and pharmaceutical applications. The product is designed and rated to IP69k providing maximum protection 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 reduction allows fast acceleration and deceleration of large loads utilizing a small, less expensive motor.
