The high-end economy lines GSN & GFE combine high performance with financial efficiency: both lines are also equipped with helical ground gears, ensuring the very least noise level and smooth running. The full needle bearing offers been especially made to reach high torques that defeat the competition for devices of the same size. All planetary carriers are manufactured as a cage worm drive servo created from solid materials. This increases quiet operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing ring ensures maximum dust and splash water safety relative to protection class IP65 in all lines.
One way to reduce backlash is by using precision gears. The focus on production in precision gears is tighter tolerances, so all over the gear is a tighter, more precise match. And the tighter fit means much less play in the apparatus teeth, which may be the trigger of backlash to begin with. Of program, precision gears are more expensive, if the application calls for high accuracy, after that precision gearing may be the way to go.
From a equipment design perspective, a simple way to lessen backlash is to ensure the teeth mesh tightly together. That is typically carried out by shortening the guts distance between gears. For pre-loading, this could be 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 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 values, the input stage is usually dimensionally smaller compared to the result stage. Its short style makes the GSD collection the ideal high-end gearbox for space limited applications. The low regular backlash of the GSD range makes it the perfect fit for highly powerful applications where highest positioning and quickness accuracy is required. The flange result generates highest torsional rigidity. For the accommodation 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 series offer the same advantages as the GSB range; the right angle form makes the GSBL line the perfect match for all dynamic applications where space is bound.
Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies tend 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 with a three-phase AC power supply. A single-phase motor could be operated by simply connecting it to a single-phase power supply via the provided capacitor. A three-phase motor does not require a capacitor. All you need is to connect the motor directly to a three-phase AC power supply.
The brand new planetary gearbox series includes the high-end gearbox lines GSD (flange gear), GSB (inline) and GSBL (angle gear) and also the high-end economy GSN and GFE lines. Particularly appropriate applications for the new range are those which place the best demands on positioning accuracy, operating noises, operating smoothness, bending rigidity and transmitted torque. The planetary gears are made to meet the highest creation requirements – all lines are equipped with precision floor helical gearing, single-piece planetary carriers and complete needle bearings.
