planetary gearbox for servo motor

The gear boxes are made from stainless, except from the insight flanges which are made of anodized aluminum. Safety class IP65 is regular – IP67 available as choice – which is acheived using a patented insight sealing and a patented output sealing system.
Standard backlash is just 5 respectively 7 arc-minute (1 resp. 2 phases), reduced backlash is merely 3 / 5 planetary gearbox for servo motor arc-min (choice) and finally micro backlash is only 1 / 31 / 3 arc-min (option).
This means that the actual backlash at a certain load is a lot Low in an APEX gear box than in virtually any other planetary gear box out there.
Gearboxes provide torque multiplication, speed reduction, and inertia matching for motor-driven systems. Servo systems, particularly, require gearboxes that can supply not only high torque with low added inertia, but also high precision and stiffness. One type of gearbox meets all these criteria while providing relatively long operating life with zero-maintenance requirements: the planetary gearbox.
A planetary gearbox includes multiple planetary gears that revolve around a central sun gear while engaging with an internal gear and rotating on their own axes. The continuous engagement of the planetary gears means the load is definitely shared by multiple teeth, allowing planetary designs to transmit high torque loads.
This load sharing among teeth also gives planetary gearboxes high torsional stiffness, making them well suited for processes that involve frequent start-stop motions or changes in rotational direction, which are normal characteristics of servo applications. Most servo applications also require very exact positioning, and planetary gearboxes were created and manufactured to have low backlash, with less than 1-2 arcmin in some cases.
Planetary gearboxes may use spur or helical gears. While spur gears can have got higher torque ratings than helical gears, helical designs have smoother operation, less noise, and higher stiffness, making helical planetary gearboxes the preferred gearbox for servo applications.
Whenever a gearbox is added to the drivetrain, the rotational swiftness delivered from the electric motor to the driven element is reduced by the quantity of the equipment ratio, which can allow the program to make better usage of the servo motor’s speed-torque characteristics. Planetary gearboxes can easily accept very high input speeds and offer speed reduced amount of up to 10:1 for standard styles, with high-speed designs providing equipment ratios (and, therefore, quickness reduction) of 100:1 or more.
Planetary gearboxes could be lubricated with either grease or oil, although a planetary gearbox for servo use (sometimes referred to as a “servo rated” or “servo” gearbox) is often lubricated with grease. In either case – grease or oil lubrication – planetary gearboxes tend to be lubricated for the life of the gearbox by the manufacturer, which eliminates maintenance for the end user.
The most important advantage of using a gearbox in a servo system is arguably its effect on the inertia of the load. The load inertia, which is definitely reflected to the motor, is decreased by the square of the apparatus ratio. So a good relatively small gear reduction can have a significant influence on the inertia ratio.
A right angle planetary gearbox with output shaft combines the advantages of a compact correct angle gearbox and the ones of a conventional planetary gearbox.

With its versatile installation options, our right angle gearboxes provide intelligent drive solutions with a concise machine concept. The output shaft gives correct angle planetary gearboxes the benefit of a proven and dependable component for the proper angle transmission of torque and rate.
