Whenever a conventional planetary gearhead is mounted to a engine, the sun gear should be aligned to compensate for runout error of the servomotor shaft. Without proper alignment, load can be unevenly distributed over the planetary gears and the drive teach operates less efficiently. Also, gear life could be shortened. These alignment changes require skills that aren’t normally obtainable in the field.
Achieving a larger speed reduction ratio takes a smaller sun equipment diameter (or an exceedingly 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 capability.
Several types of gear trains, including people that have planetary gears, are generally used to acquire this optimum reduction ratio. Planetary equipment trains provide high stiffness and low backlash (necessary for accurate operation), plus actually load distribution (to acquire optimum torque). Some planetary versions combine external-tooth pinion-and-gear pieces with planetary gear sections to simplify installation and boost swiftness. These hybrid gearheads are explained later.
A simple planetary gearhead has a few limitations regarding simple installation, load capacity, and speed, all of which are related to sunlight gear.
As a rule, the designer usually obtains the the best speed reduction ratio by matching the inertia of the engine and gearbox with the inertia of the driven load. This inertia complementing 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 created for sterile manufacturing conditions. The product’s smooth surface and curved contour permits easy cleaning and bacteria-free surfaces, perfect for food processing and servo reducer pharmaceutical applications. The product is designed and rated to IP69k providing maximum safety against contaminant ingress in addition to leak free operation.
Servomotor selection usually begins with the designer wanting to reduce the electric motor size by utilizing a gearbox to lessen speed and increase torque. Speed reduction allows fast acceleration and deceleration of huge loads utilizing a small, less costly motor.
