The high-end economy lines GSN & GFE combine high performance with economic efficiency: both lines are also equipped with helical ground gears, ensuring a minimum noise level and smooth running. The full needle bearing offers been especially made to reach high torques that defeat the competition for units of the same size. All planetary carriers are produced as a cage created from solid materials. This increases silent operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft zero backlash planetary gearbox sealing band ensures maximum dirt and splash water security in accordance with protection class IP65 in all lines.
One method to reduce backlash is to use precision gears. The focus on manufacturing in precision gears is definitely tighter tolerances, so all around the gear will be a tighter, more specific suit. And the tighter match means much less play in the apparatus teeth, which is the trigger of backlash in the first place. Of training course, precision gears are more expensive, if the application calls for high accuracy, then precision gearing may be the way to go.
From a equipment design perspective, an easy way to lessen backlash is to make sure one’s teeth mesh tightly together. That is typically completed by shortening the guts distance between gears. As for pre-loading, this is often done utilizing a spring mechanism to carry the gears firmly set up. This also eliminates the play between the gear teeth and therefore eliminates backlash.
Of course, the kind of gears used can also have a large impact on the quantity of backlash. So for instance, some equipment types such as strain wave gears, or harmonic gear drives, have zero backlash.
The GSD, GSB & GSBL high-end gearbox lines are constructed in a space-optimized, two-stage design. Due to the lower torque ideals, the input stage is usually dimensionally smaller than the result stage. Its short design makes the GSD collection the ideal high-end gearbox for space limited applications. The low standard backlash of the GSD series makes it an ideal fit for highly dynamic applications where highest positioning and velocity accuracy is necessary. The flange output produces highest torsional rigidity. For the lodging of especially high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or higher. The GSB line stands for high performance in combination with low backlash and high precision. Its robust, one-piece housing permits a higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL line provide same advantages as the GSB series; the right angle form makes the GSBL line the perfect match for all powerful applications where space is limited.
Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies have a tendency to increase backlash.
AC motors and gear motors include single-stage motors used with a single-stage AC power and three-stage motors used in combination with a three-stage AC power. A single-phase motor could be operated by simply connecting it to a single-phase power via the provided capacitor. A three-phase motor does not require a capacitor. All you have to is to connect the motor directly to a three-stage AC power supply.
The new planetary gearbox series includes the high-end gearbox lines GSD (flange equipment), GSB (inline) and GSBL (angle gear) along with the high-end economy GSN and GFE lines. Particularly appropriate applications for the brand new range are those that place the best demands on positioning precision, operating noises, working smoothness, bending rigidity and transmitted torque. The planetary gears are created to meet the highest production requirements – all lines include precision ground helical gearing, single-piece planetary carriers and full needle bearings.
