When a conventional planetary gearhead is mounted to a electric motor, the sun gear should be aligned to compensate 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 easily. Also, gear life can be shortened. These alignment changes require skills that aren’t normally obtainable in the field.
Achieving a more substantial speed reduction ratio requires a smaller sun gear diameter (or an exceedingly large ring gear). This smaller sun gear is usually integral with its shaft, which must be smaller aswell, thereby reducing its strength and its own torque or load capability.
servo reducer Several types of gear trains, including those with planetary gears, are generally used to obtain this optimum reduction ratio. Planetary gear trains offer high stiffness and low backlash (needed for accurate operation), plus even load distribution (to acquire optimum torque). Some planetary versions combine external-tooth pinion-and-gear models with planetary equipment sections to simplify installation and boost swiftness. These hybrid gearheads are described later.
A simple 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 ideal speed reduction ratio by matching the inertia of the motor and gearbox with the inertia of the driven load. This inertia complementing 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 precisely control the positioning of the motors path and rotation distance.
Cone Drive’s stainless steel precision movement gearboxes are designed for sterile manufacturing conditions. The product’s smooth surface and curved contour permits easy cleaning and bacteria-free surfaces, perfect for meals digesting and pharmaceutical applications. The merchandise is designed and ranked to IP69k offering maximum protection against contaminant ingress in addition to leak free operation.
Servomotor selection usually starts with the designer seeking to reduce the motor size by using a gearbox to lessen speed and enhance torque. Speed reduction allows rapid acceleration and deceleration of large loads utilizing a small, less expensive motor.
