Whenever a conventional planetary gearhead is mounted to a motor, the sun gear must be aligned to pay for runout error of the servomotor shaft. Without proper alignment, load is unevenly distributed over the planetary gears and the drive train operates less smoothly. Also, gear life can be shortened. These alignment changes require skills that aren’t normally available in the field.
Achieving a servo motor and gearbox larger speed reduction ratio takes a smaller sun equipment diameter (or an exceedingly large ring equipment). This smaller sun equipment is usually integral using its shaft, which must be smaller as well, thereby reducing its power and its own torque or load capacity.
Various kinds gear trains, including those with planetary gears, are generally used to obtain this optimum reduction ratio. Planetary gear trains provide high stiffness and low backlash (needed for accurate operation), plus even load distribution (to acquire maximum torque). Some planetary variations combine external-tooth pinion-and-gear units with planetary equipment sections to simplify set up and boost acceleration. These hybrid gearheads are defined later.
A basic planetary gearhead has a few limitations regarding simple installation, load capacity, and speed, which are related to sunlight gear.
Generally, the designer usually obtains the optimum speed reduction ratio by matching the inertia of the motor and gearbox with the inertia of the driven load. This inertia complementing minimizes power reduction in the motor, which makes it run more efficiently.
Servo motors deliver precise control of position, velocity, and acceleration in the closed-loop systems of servomechanisms. Servo motors need a servo drive – this uses the opinions data to specifically control the position of the motors path and rotation distance.
Cone Drive’s stainless precision movement gearboxes are designed for sterile manufacturing conditions. The product’s smooth surface area and curved contour permits easy cleaning and bacteria-free surfaces, ideal for food digesting and pharmaceutical applications. The product is designed and ranked to IP69k providing maximum protection against contaminant ingress as well as leak free operation.
Servomotor selection usually starts with the designer seeking to reduce the motor size by utilizing a gearbox to reduce speed and boost torque. Speed reduction allows rapid acceleration and deceleration of huge loads utilizing a small, less costly motor.
