Whenever a conventional planetary gearhead is mounted to a electric motor, the sun gear should be aligned to pay for runout error of the servomotor shaft. Without proper alignment, load is certainly unevenly distributed over the planetary gears and the drive teach operates less smoothly. Also, gear life can be shortened. These alignment adjustments require skills that are not normally available in the field.
Achieving a larger speed reduction ratio takes 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 as well, thereby reducing its strength and its torque or load capacity.
Several types of gear trains, including those with planetary gears, are commonly used to acquire this ideal reduction ratio. Planetary gear trains provide high stiffness and low backlash (needed for accurate procedure), plus actually load distribution (to acquire optimum torque). Some planetary variations combine external-tooth pinion-and-gear sets with planetary equipment sections to simplify set up and boost swiftness. These hybrid gearheads are defined later.
A simple planetary gearhead has a few limitations regarding simple installation, load capacity, and speed, all of which are related to the sun gear.
Generally, the designer usually obtains the ideal 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, which makes 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 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 and curved contour allows for easy cleaning and bacteria-free surfaces, perfect for meals digesting 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 lessen speed and enhance torque. Speed reduction allows fast acceleration and deceleration of huge loads utilizing a small, less expensive motor.
