The high-end economy lines GSN & GFE combine high performance with financial efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The entire needle bearing provides been especially designed to reach high torques that defeat the competition for devices of the same size. All planetary carriers are manufactured as a cage made from solid material. This increases peaceful operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing band ensures maximum dust and splash water protection 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 certainly tighter tolerances, so all over the gear will be a tighter, more specific match. And the tighter fit means much less play in the apparatus teeth, which is the cause of backlash in the first place. Of course, precision gears are more costly, 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 carried out by shortening the guts distance between gears. For pre-loading, this can be done utilizing a spring mechanism to carry the gears firmly in place. This also eliminates the enjoy between the gear teeth and therefore eliminates backlash.
Of course, the kind of gears used may also have a huge impact on the amount of backlash. So for example, some gear 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. Because of the lower torque ideals, the input stage can be dimensionally smaller compared to the result stage. Its short design makes the GSD collection the ideal high-end gearbox for space restricted applications. The low regular backlash of the GSD collection makes it an ideal fit for highly powerful applications where highest positioning and swiftness accuracy is necessary. The flange output generates highest torsional rigidity. For the accommodation of especially high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or more. The GSB line stands for high performance in mixture 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 collection an ideal match for all dynamic 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 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 need 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 suitable applications for the brand new range are those that place the highest demands on positioning precision, operating noises, running smoothness, bending rigidity and transmitted torque. The planetary gears are created to meet the highest creation requirements – all lines are zero backlash planetary gearbox china equipped with precision surface helical gearing, single-piece planetary carriers and full needle bearings.
