The high-end economy lines GSN & GFE combine powerful with financial efficiency: both lines are also built 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 products of the same size. All planetary carriers are manufactured as a cage made from solid materials. This increases noiseless operating characteristics while at the same time improving positioning precision and reducing backlash. Yet another shaft sealing band ensures maximum dirt and splash water safety relative to protection course IP65 in every lines.
One method to reduce backlash is to use precision gears. The focus on manufacturing in precision gears is certainly tighter tolerances, so all around the gear will be a tighter, more exact match. And the tighter match means less play in the apparatus teeth, which is the cause of backlash to begin with. Of program, precision gears are more expensive, if the application calls for high accuracy, then precision gearing could be the way to go.
From a equipment design perspective, an easy way to lessen backlash is to make sure the teeth mesh tightly together. That is typically performed 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 eliminates the enjoy between the gear teeth and therefore eliminates backlash.
Of course, the type of gears used may also have a large impact on the quantity of backlash. So for example, some equipment types such as stress wave gears, or harmonic equipment drives, have zero backlash.
The GSD, GSB & GSBL high-end gearbox lines are constructed in a space-optimized, two-stage design. Because of the lower torque values, the input stage is usually dimensionally smaller than the result stage. Its short style makes the GSD range the perfect high-end gearbox for space limited 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 required. The flange result generates highest torsional rigidity. For the lodging of particularly high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or more. The GSB line stands for 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 series provide same worm drive servo china advantages as the GSB range; the right angle form makes the GSBL series an ideal 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 and three-phase motors used in combination with a three-phase AC power supply. A single-phase motor can be operated by simply linking it to a single-phase power supply via the supplied capacitor. A three-phase motor will not require a capacitor. All you need is for connecting the motor right 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 designed to meet the highest creation requirements – all lines include precision surface helical gearing, single-piece planetary carriers and full needle bearings.
