When a conventional 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 is definitely 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 takes a smaller sun gear diameter (or an exceptionally large ring gear). This smaller sun equipment is usually integral using its shaft, which should be smaller as well, thereby reducing its power and its own torque or load capability.
Various kinds gear trains, including those with planetary gears, are generally used to acquire this servo motor and gearbox maximum reduction ratio. Planetary equipment trains offer high stiffness and low backlash (necessary for accurate operation), plus even load distribution (to acquire maximum torque). Some planetary variations combine external-tooth pinion-and-gear pieces with planetary gear sections to simplify set up and boost speed. These hybrid gearheads are referred to later.
A basic planetary gearhead has some limitations regarding ease of installation, load capacity, and speed, which are related to the sun gear.
As a rule, the designer usually obtains the maximum speed reduction ratio by matching the inertia of the electric 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 require a servo drive – this uses the opinions data to precisely control the positioning of the motors direction and rotation distance.
Cone Drive’s stainless steel precision motion gearboxes are designed for sterile manufacturing conditions. The product’s smooth surface and curved contour permits easy cleaning and bacteria-free surfaces, ideal for food processing and pharmaceutical applications. The merchandise is designed and rated to IP69k providing maximum safety against contaminant ingress along with leak free operation.
Servomotor selection usually begins with the designer seeking to reduce the motor size by utilizing a gearbox to reduce speed and enhance torque. Speed reduction allows quick acceleration and deceleration of huge loads using a small, less costly motor.
