Smoothness and lack of ripple are crucial for the printing of elaborate color images on reusable plastic material cups available at fast-food chains. The colour image comprises of millions of tiny ink spots of many colours and shades. The complete glass is printed in a single complete (unlike regular color separation where each color is published separately). The gearheads must function efficiently enough to synchronize ink blankets, printing plates, and glass rollers without presenting any ripple or inaccuracies that may smudge the picture. In cases like this, the hybrid gearhead reduces motor shaft runout mistake, which reduces roughness.
Sometimes a motor’s capability may be limited to the point where it needs gearing. As servo manufacturers develop more powerful motors that can muscle tissue applications through more complicated moves and create servo motor gearbox higher torques and speeds, these motors require gearheads equal to the task.
Interestingly, no more than a third of the motion control systems operating use gearing at all. There are, of course, reasons to do so. Using a gearhead with a servo motor or using a gearmotor can enable the use of a smaller motor, therefore reducing the machine size and cost. There are three main 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 teeth on each gear develop a ratio. If a electric motor can generate 100 in-lbs of torque, and a 5:1 ratio equipment head is mounted on its result, the resulting torque will become close to 500 in-lbs.
When a motor is operating at 1,000 rpm and a 5:1 ratio gearhead is mounted on it, the velocity at the output will be 200 rpm. This speed reduction can improve system overall performance because many motors usually do not operate effectively at very low rpm. For example, look at a 
stone-grinding mechanism that requires the motor to run at 15 rpm. This slow swiftness makes turning the grinding wheel hard because the motor tends to cog. The variable level of resistance of the stone being floor also hinders its simple turning. With the addition of a 100:1 gearhead and letting the engine run at 1,500 rpm, the engine and gear head provides smooth rotation while the gearhead output offers a more constant force 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 result is higher inertial mismatches between servo motors and the loads they want to control. The utilization of a gearhead to raised match the inertia of the engine to the inertia of the strain can enable the use of a smaller motor and outcomes in a more responsive system that’s easier to tune.
