Whenever a conventional planetary gearhead is mounted to a motor, the sun gear must be aligned to compensate for runout error of the servomotor shaft. Without proper alignment, load is usually unevenly distributed over the planetary gears and the drive teach operates less smoothly. Also, gear life could be shortened. These alignment modifications require skills that aren’t normally obtainable in the field.
Achieving a larger speed reduction ratio takes a smaller sun gear diameter (or an exceedingly large ring equipment). This smaller sun gear is usually integral with its shaft, which should 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 commonly used to obtain this ideal reduction ratio. Planetary equipment trains provide 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 units with planetary equipment sections to simplify installation and boost rate. These hybrid gearheads are referred to later.
A basic planetary gearhead has several limitations regarding simple installation, load capacity, and speed, which are related to sunlight gear.
As a rule, the designer usually obtains the the best possible speed reduction ratio by matching the inertia of the motor and gearbox with the inertia of the driven load. This inertia matching 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 servo motor and gearbox servomechanisms. Servo motors require a servo drive – this uses the opinions data to precisely control the position of the motors path and rotation distance.
Cone Drive’s stainless steel precision motion gearboxes are made for sterile manufacturing environments. The product’s smooth surface and curved contour permits easy cleaning and bacteria-free surfaces, ideal for food digesting and pharmaceutical applications. The product is designed and rated to IP69k offering maximum security against contaminant ingress in addition to leak free operation.
Servomotor selection usually starts with the designer seeking to reduce the engine size by using a gearbox to reduce speed and enhance torque. Speed reduction allows fast acceleration and deceleration of large loads utilizing a small, less expensive motor.
