When a conventional planetary gearhead is mounted to a electric motor, the sun gear must be aligned to compensate for runout error of the servomotor shaft. Without proper alignment, load is unevenly distributed over the planetary gears and the drive teach operates less smoothly. Also, gear life can be shortened. These alignment changes require skills that are not normally available in the field.
Achieving a larger speed reduction ratio requires a smaller sun equipment diameter (or an exceptionally large ring gear). This smaller sun gear is usually integral using its shaft, which should be smaller aswell, thereby reducing its power and its own torque or load capability.
servo reducer Various kinds gear trains, including people that have 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 actually load distribution (to acquire maximum torque). Some planetary versions combine external-tooth pinion-and-gear sets with planetary equipment sections to simplify installation and boost swiftness. These hybrid gearheads are referred to later.
A basic planetary gearhead has several limitations regarding ease of installation, load capacity, and speed, which are related to the sun 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 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 specifically control the positioning of the motors direction and rotation distance.
Cone Drive’s stainless steel precision movement gearboxes are designed for sterile manufacturing environments. The product’s smooth surface area and curved contour allows for easy cleaning and bacteria-free surfaces, ideal for food digesting and pharmaceutical applications. The merchandise is designed and ranked to IP69k offering maximum safety against contaminant ingress in addition to leak free operation.
Servomotor selection usually starts with the designer seeking to reduce the electric motor size by using a gearbox to reduce speed and increase torque. Speed reduction allows speedy acceleration and deceleration of huge loads using a small, less costly motor.
