Whenever a conventional servo reducer planetary gearhead is mounted to a engine, the sun gear must be aligned to pay for runout error of the servomotor shaft. Without proper alignment, load can be 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 available in the field.
Achieving a larger speed reduction ratio takes a smaller sun gear diameter (or an exceptionally large ring equipment). This smaller sun gear is usually integral using 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 generally used to obtain this the best possible reduction ratio. Planetary equipment trains offer high stiffness and low backlash (needed for accurate procedure), plus also load distribution (to acquire maximum torque). Some planetary variations combine external-tooth pinion-and-gear units with planetary gear sections to simplify set up and boost acceleration. These hybrid gearheads are defined later.
A simple planetary gearhead has several limitations regarding ease of installation, load capacity, and speed, which are related to sunlight gear.
Generally, the designer usually obtains the optimum speed decrease ratio by matching the inertia of the electric motor and gearbox with the inertia of the driven load. This inertia coordinating minimizes power reduction in the motor, making it run more efficiently.
Servo motors deliver precise control of position, velocity, and acceleration in the closed-loop systems of servomechanisms. Servo motors require a servo drive – this uses the feedback data to precisely control the positioning of the motors path and rotation distance.
Cone Drive’s stainless precision movement gearboxes are made for sterile manufacturing environments. The product’s smooth surface area and curved contour allows for easy cleaning and bacteria-free surfaces, ideal for food processing and pharmaceutical applications. The product is designed and rated to IP69k providing maximum security against contaminant ingress along with leak free operation.
Servomotor selection usually starts with the designer wanting to reduce the electric motor size by using a gearbox to reduce speed and boost torque. Speed decrease allows speedy acceleration and deceleration of huge loads using a small, less costly motor.
