SEW EURODRIVE GEAR MOTOR CATALOG PDF

What is a servo gear unit? Servo gear units Like all gear units, servo gear units serve as converters of torque and speed and are therefore the central component of every servo gearmotor. The special feature of a servo gear unit: Thanks to its high torsional stiffness while maintaining a very low to constant rotational clearance, it enables extremely high acceleration and high torques. Servo gear units are therefore indispensable for plant operators whose applications require high positioning accuracy, short cycle times, exact speeds, high processing speeds, and maximum dynamics. How do servo gear units work?

What is a servo gear unit? Servo gear units Like all gear units, servo gear units serve as converters of torque and speed and are therefore the central component of every servo gearmotor.

The special feature of a servo gear unit: Thanks to its high torsional stiffness while maintaining a very low to constant rotational clearance, it enables extremely high acceleration and high torques. Servo gear units are therefore indispensable for plant operators whose applications require high positioning accuracy, short cycle times, exact speeds, high processing speeds, and maximum dynamics.

How do servo gear units work? A servo gear unit reduces the speed of a motor. It transmits the flow of force in different ways depending on how its gearing and gear unit stages are arranged and operate. The gear ratio i is therefore one of the most important characteristic values of a servo gear unit: It specifies the ratio of the input speed on the motor side to the output speed on the machine side.

Low-backlash processing and optimized gearing ensure that the servo gear unit is capable of receiving higher overhung loads than standard gear units and transmitting high acceleration torques at high speeds. What types of servo gear unit are available? Planetary servo gear units always transmit the flow of force coaxially. In their center, there is a sun gear that turns in the direction of rotation and at the speed of the motor.

Three or more planet gears that transmit the received force to the outer annulus gear on the output side rotate around this sun gear. Due to this design, the input shaft and output shaft move in the same direction. That is: They have the same direction of rotation. In contrast, the gearing in a helical-bevel servo gear unit diverts the flow of force at a right angle. The input shaft and output shaft are therefore perpendicular to each other and they rotate in opposite directions.

Low-backlash servo gear units from our modular system The outstanding features of servo gearmotors are definitely power, dynamics, and precision. Use our modular system and see the multitude of gear unit and motor constellations in our servo gear unit section for yourself: For example, you can combine our PS. AC motors.

Or instead choose a design with our BS. F helical-bevel servo gear units. The low-backlash planetary servo gear units in our PS. This feature allows you to save plenty of space while using them. The main feature of the low-maintenance helical-bevel servo gear units in the BS.

F series is their durability and flexibility. Another benefit: Their rotational clearance remains constant over the entire gear unit service life. Do you have a specific request and need assistance? Just send us a message with your questions.

Nonetheless, they offer a power range from to 18, Nm. We think they are always a good choice when space is limited. Design and torque are perfectly matched to limited installation space. The figure shows a gearmotor with a parallel-shaft helical gear unit The figure shows a gearmotor with a parallel-shaft helical gear unit One of our best gear units for limited installation space. A wide range of mounting positions and variants enable a broad spectrum of applications even under difficult installation conditions — without having to compromise on the performance. And what applies to many of our gear units: long operating lives without maintenance and wear-free gearing with a high fatigue strength. With a high torque rating from Nm to 18, Nm, our parallel-shaft helical gear units offer great performance in many conveying and processing applications.

Getriebemotor Getriebemotor Bei einem Getriebemotor handelt es sich um eine homogene und kompakte Einheit bestehend aus Getriebe und Motor. Wie funktioniert ein Getriebemotor? Die zentrale Rolle im Getriebemotor nimmt das Getriebe mit seinen Getriebestufen, den Zahnradpaaren, ein. Das Getriebe funktioniert somit als Wandler von Drehmoment und Drehzahl. Welche Typen Getriebemotoren gibt es? Vor allem die Kraftflussrichtung des Getriebes bestimmt den Typ des Getriebemotors.
