The high-end economy lines GSN & GFE combine powerful with financial efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The entire needle bearing offers been especially made to reach high torques that beat the competition for devices of the same size. All planetary carriers are produced as a cage created from solid materials. This increases peaceful operating characteristics while at the same time improving servo planetary gearbox positioning accuracy and reducing backlash. An additional shaft sealing ring ensures maximum dust and splash water security in accordance with protection course IP65 in all lines.
One method to reduce backlash is to use precision gears. The focus on manufacturing in precision gears is tighter tolerances, so all over the gear will be a tighter, more specific match. And the tighter match means less play in the apparatus teeth, which is the cause of backlash to begin with. Of training course, precision gears are more expensive, but if the application calls for high accuracy, after that precision gearing may be the way to go.
From a equipment design perspective, an easy way to reduce backlash is to ensure the teeth mesh tightly together. This is typically done by shortening the guts distance between gears. As for pre-loading, this is often done using a spring mechanism to carry the gears firmly set up. This also eliminates the enjoy between the gear teeth and therefore eliminates backlash.
Of course, the kind of gears used may also have a large impact on the amount of backlash. So for instance, some equipment types such as stress 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 values, the input stage is certainly dimensionally smaller than the output stage. Its short design makes the GSD range the ideal high-end gearbox for space restricted applications. The low standard backlash of the GSD range makes it an ideal fit for highly powerful applications where highest positioning and rate accuracy is necessary. The flange result creates highest torsional rigidity. For the accommodation 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 combination with low backlash and high precision. Its robust, one-piece housing allows for a high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL range offer the same advantages as the GSB collection; 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 equipment motors include single-stage motors used in combination with a single-stage AC power supply and three-phase motors used in combination with a three-phase 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 gear), GSB (inline) and GSBL (angle gear) along with the high-end economy GSN and GFE lines. Particularly suitable applications for the brand new range are those which place the highest demands on positioning precision, operating noises, operating smoothness, bending rigidity and transmitted torque. The planetary gears are made to meet the highest creation requirements – all lines include precision surface helical gearing, single-piece planetary carriers and full needle bearings.
