Whenever a conventional planetary gearhead is mounted to a electric motor, the sun gear must 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 teach operates less smoothly. Also, gear life can be shortened. These alignment modifications require skills that are not normally available in the field.
Achieving a larger speed reduction ratio requires a smaller sun gear diameter (or an exceedingly large ring gear). This smaller sun equipment is usually integral with its shaft, which must be smaller aswell, thereby reducing its power and its torque or load capacity.
Various kinds gear trains, including people that have planetary gears, are 
commonly used to obtain this the best reduction ratio. Planetary equipment servo motor and gearbox trains provide high stiffness and low backlash (needed for accurate operation), plus also load distribution (to acquire maximum torque). Some planetary versions combine external-tooth pinion-and-gear pieces with planetary gear sections to simplify set up and boost rate. These hybrid gearheads are explained later.
A basic planetary gearhead has some limitations regarding ease of installation, load capacity, and speed, all of which are related to the sun gear.
Generally, 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, which makes it run more efficiently.
Servo motors deliver precise control of placement, velocity, and acceleration in the closed-loop systems of servomechanisms. Servo motors require a servo drive – this uses the feedback data to specifically control the positioning of the motors direction and rotation distance.
Cone Drive’s stainless precision movement gearboxes are designed for sterile manufacturing environments. The product’s smooth surface area and curved contour allows for easy cleaning and bacteria-free surfaces, ideal for meals processing and pharmaceutical applications. The product is designed and rated to IP69k offering maximum safety against contaminant ingress in addition to leak free operation.
Servomotor selection usually starts with the designer wanting to reduce the motor size by utilizing a gearbox to lessen speed and enhance torque. Speed reduction allows rapid acceleration and deceleration of huge loads using a small, less costly motor.
