The gear boxes are made from stainless, except from the insight flanges which are constructed of anodized aluminum. Protection class IP65 is standard – IP67 obtainable as choice – which is acheived using a patented input sealing and a patented output sealing system.
Standard backlash is merely 5 respectively 7 arc-minute (1 resp. 2 phases), reduced backlash is just 3 / 5 arc-min (choice) and finally micro backlash is only one third1 / 3 arc-min (option).
This means that the actual backlash at a particular load is a lot Reduced an APEX gear box than in any other planetary gearbox for servo motor planetary gear box available.
Gearboxes provide torque multiplication, speed decrease, and inertia matching for motor-driven systems. Servo systems, specifically, require gearboxes that may supply not only high torque with low added inertia, but also high precision and stiffness. One type of gearbox meets each one of these requirements while providing relatively long operating life with zero-maintenance requirements: the planetary gearbox.
A planetary gearbox contains multiple planetary gears that revolve around a central sunlight gear while engaging with an internal gear and rotating by themselves axes. The continuous engagement of the planetary gears means the strain is definitely shared by multiple the teeth, allowing planetary styles 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 additionally require very specific positioning, and planetary gearboxes were created and manufactured to have low backlash, with as little as 1-2 arcmin in some instances.
Planetary gearboxes may use spur or helical gears. While spur gears can have got higher torque ratings than helical gears, helical styles have smoother operation, less sound, and higher stiffness, making helical planetary gearboxes the favored gearbox for servo applications.
Whenever a gearbox is added to the drivetrain, the rotational velocity delivered from the motor to the driven element is reduced by the quantity of the equipment ratio, that may allow the program to make better utilization of the servo motor’s speed-torque characteristics. Planetary gearboxes have the ability to accept high input speeds and offer speed reduced amount of up to 10:1 for standard designs, with high-speed styles providing equipment ratios (and, therefore, acceleration reduction) of 100:1 or higher.
Planetary gearboxes could be lubricated with either grease or oil, although a planetary gearbox for servo use (sometimes known as a “servo rated” or “servo” gearbox) is often lubricated with grease. In either case – grease or essential oil lubrication – planetary gearboxes tend to be lubricated for the life span of the gearbox by the product manufacturer, which eliminates maintenance for the finish user.
The most important advantage of using a gearbox in a servo system is arguably its influence on the inertia of the strain. The load inertia, which is definitely reflected to the electric motor, is reduced by the square of the apparatus ratio. So even a relatively small gear decrease can have a significant influence on the inertia ratio.
The right angle planetary gearbox with output shaft combines the benefits of a compact correct angle gearbox and the ones of a typical planetary gearbox.

With its versatile mounting options, our right angle gearboxes offer intelligent drive solutions with a concise machine concept. The output shaft gives right angle planetary gearboxes the benefit of a proven and dependable component for the proper angle transmitting of torque and swiftness.
