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 entire needle bearing has been especially made to reach high torques that defeat the competition for devices of the same size. All planetary carriers are produced as a cage made from solid material. This increases peaceful operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing ring ensures maximum dirt and splash water security relative to protection course IP65 in every lines.
One method to reduce zero backlash planetary gearbox backlash is by using precision gears. The focus on manufacturing in precision gears is usually tighter tolerances, so all around the gear will be a tighter, more exact suit. And the tighter suit means less play in the gear teeth, which is the trigger of backlash to begin with. Of course, precision gears are more expensive, but if the application calls for high accuracy, after that precision gearing could be the way to go.
From a gear design perspective, an easy way to reduce backlash is to make sure one’s teeth mesh tightly together. This is typically performed by shortening the guts distance between gears. For pre-loading, this is often done utilizing 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 type of gears used may also have a huge impact on the amount of backlash. So for instance, some equipment types such as strain 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 is dimensionally smaller compared to the result stage. Its short design makes the GSD range the ideal high-end gearbox for space limited applications. The low regular backlash of the GSD collection makes it the perfect fit for highly dynamic applications where highest positioning and quickness accuracy is required. 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 means high performance in mixture with low backlash and high precision. Its robust, one-piece housing allows for a higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL range 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 tend to increase backlash.
AC motors and gear motors include single-phase motors used in combination with a single-phase AC power supply and three-phase motors used in combination with a three-stage AC power. A single-phase motor can be operated by simply linking it to a single-phase power via the provided 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 gear), GSB (inline) and GSBL (angle gear) and also the high-end economy GSN and GFE lines. Particularly ideal applications for the new range are those that place the best demands on positioning accuracy, operating noises, working smoothness, bending rigidity and transmitted torque. The planetary gears are made to meet the highest creation requirements – all lines include precision floor helical gearing, single-piece planetary carriers and complete needle bearings.
