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 entire needle bearing provides 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 made from solid material. This increases silent operating characteristics while at the same time improving positioning precision and reducing backlash. An additional shaft sealing band ensures maximum dust and splash water protection in accordance with protection class IP65 in all lines.
One way to reduce backlash is to use precision gears. The concentrate on manufacturing in precision gears is usually tighter tolerances, so all around the gear is a tighter, more precise suit. And the tighter suit means less play in the apparatus teeth, which is the trigger of backlash in the first place. Of program, precision gears are more expensive, but 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 ensure one’s teeth mesh tightly together. This is typically done by shortening the center distance between gears. For pre-loading, this could be done utilizing a spring mechanism to hold the gears firmly in place. This also servo planetary gearbox eliminates the perform between your gear teeth and thus eliminates backlash.
Of course, the kind of gears used can also have a huge impact on the quantity of backlash. So for instance, some equipment types such as stress wave gears, or harmonic gear drives, possess 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 certainly dimensionally smaller compared to the output stage. Its short design makes the GSD collection the perfect high-end gearbox for space limited applications. The low regular backlash of the GSD line makes it the perfect fit for highly powerful applications where highest positioning and quickness accuracy is required. The flange result 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 more. The GSB line means high performance in combination with low backlash and high precision. Its robust, one-piece housing permits a high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL line offer the same advantages as the GSB series; the right angle shape makes the GSBL line the perfect match for all powerful applications where space is bound.
Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies have a tendency to increase backlash.
AC motors and gear motors include single-stage motors used in combination with a single-stage AC power supply and three-stage motors used with a three-phase AC power. A single-phase motor can be operated by simply linking it to a single-phase power supply via the provided capacitor. A three-phase motor does not need a capacitor. All you have to is for connecting 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) as well as the high-end economy GSN and GFE lines. Particularly suitable applications for the new range are those which place the best demands on positioning precision, operating noises, running smoothness, bending rigidity and transmitted torque. The planetary gears are designed to meet the highest production requirements – all lines include precision floor helical gearing, single-piece planetary carriers and full needle bearings.
