One way to reduce worm drive servo backlash is to use precision gears. The focus on production in precision gears is definitely tighter tolerances, so all over the gear will be a tighter, more specific suit. And the tighter match means much less play in the gear teeth, which is the trigger of backlash to begin with. Of training course, precision gears are more expensive, but if the application demands high accuracy, after that precision gearing may be the way to go.
From a equipment design perspective, a simple way to reduce backlash is to ensure the teeth mesh tightly together. That is typically completed by shortening the guts distance between gears. For pre-loading, this can be done using a spring mechanism to hold the gears firmly in place. This also eliminates the play between the gear teeth and therefore eliminates backlash.
Of course, the kind of gears used may also have a huge impact on the quantity of backlash. So for instance, some gear types such as stress wave gears, or harmonic gear drives, possess zero backlash.
two-stage design. Because of the lower torque values, the input stage can be dimensionally smaller than the result stage. Its short design makes the GSD collection the perfect high-end gearbox for space restricted applications. The low regular backlash of the GSD range makes it an ideal fit for highly powerful applications where highest positioning and speed accuracy is necessary. The flange result produces highest torsional rigidity. For the lodging of particularly high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or more. The GSB line means high performance in mixture with low backlash and high precision. Its robust, one-piece housing allows for a higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL collection offer the same advantages as the GSB line; the right angle form makes the GSBL series the perfect match for all dynamic applications where space is limited.
Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies tend to increase backlash.
AC motors and gear motors include single-phase motors used with a single-phase AC power supply and three-stage motors used in combination with a three-phase AC power supply. A single-phase motor can be operated by simply linking it to a single-phase power via the supplied capacitor. A three-phase motor does not require a capacitor. All you need is for connecting the motor right to a three-phase AC power supply.
The new planetary gearbox series includes the high-end gearbox lines GSD (flange equipment), GSB (inline) and GSBL (angle gear) as well as the high-end economy GSN and GFE lines. Particularly ideal applications for the new range are those that place the best demands on positioning precision, operating noises, operating smoothness, bending rigidity and transmitted torque. The planetary gears are created to meet the highest creation requirements – all lines include precision surface helical gearing, single-piece planetary carriers and full needle bearings.
