servo motor gearbox

Smoothness and lack of ripple are essential for the printing of elaborate color images on reusable plastic material cups available at fast-food chains. The color image is made up of an incredible number of tiny ink dots of many colours and shades. The entire glass is printed in one pass (unlike regular color separation where each color is usually printed separately). The gearheads must servo motor gearbox function smoothly enough to synchronize ink blankets, printing plates, and glass rollers without introducing any ripple or inaccuracies that may smudge the image. In this case, the hybrid gearhead decreases motor shaft runout error, which reduces roughness.
At times a motor’s capability may be limited to the main point where it requires gearing. As servo manufacturers develop more powerful motors that can muscles applications through more complicated moves and generate higher torques and speeds, these motors require gearheads equal to the task.

Interestingly, no more than a third of the motion control systems in service use gearing at all. There are, of training course, good reasons to do therefore. Utilizing a gearhead with a servo electric motor or using a gearmotor can enable the usage of a smaller motor, therefore reducing the machine size and cost. There are three principal advantages of going with gears, each which can enable the use of smaller sized motors and drives and therefore lower total system cost:

Torque multiplication. The gears and amount of tooth on each gear make a ratio. If a electric motor can generate 100 in-lbs of torque, and a 5:1 ratio equipment head is mounted on its output, the resulting torque will be close to 500 in-lbs.
When a motor is running at 1,000 rpm and a 5:1 ratio gearhead is attached to it, the speed at the output will be 200 rpm. This speed decrease can improve system performance because many motors usually do not operate effectively at suprisingly low rpm. For example, consider a stone-grinding mechanism that requires the motor to run at 15 rpm. This slow speed makes turning the grinding wheel challenging because the motor will cog. The variable level of resistance of the stone being ground also hinders its ease of turning. With the addition of a 100:1 gearhead and letting the motor run at 1,500 rpm, the motor and gear head provides smooth rotation as the gearhead output provides a more constant pressure with its output rotating at 15 rpm.
Inertia matching. Servo motors generate more torque in accordance with frame size thanks to lightweight components, dense copper windings, and high-energy magnets. The effect is greater inertial mismatches between servo motors and the loads they want to control. The use of a gearhead to raised match the inertia of the motor to the inertia of the strain can enable the usage of a smaller motor and results in a more responsive system that is easier to tune.
