The equipment boxes are constructed with stainless, except from the input flanges which are made of anodized aluminum. Safety class IP65 is regular – IP67 obtainable as option – which is acheived using a patented input sealing and a patented result sealing system.
Standard backlash is merely 5 respectively 7 arc-minute (1 resp. 2 phases), planetary gearbox for servo motor reduced backlash is just 3 / 5 arc-min (option) and lastly micro backlash is 1 / 31 / 3 arc-min (option).
This means that the actual backlash at a specific load is MUCH Reduced an APEX gear box than in virtually any other planetary gear box in the marketplace.
Gearboxes provide torque multiplication, speed decrease, and inertia matching for motor-driven systems. Servo systems, specifically, require gearboxes that can 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 lengthy operating life with low 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 on their own axes. The continuous engagement of the planetary gears means the load can be shared by multiple tooth, 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 common characteristics of servo applications. Most servo applications also require very specific positioning, and planetary gearboxes are designed and manufactured to have low backlash, with as little as 1-2 arcmin in some instances.
Planetary gearboxes can use spur or helical gears. While spur gears can have got higher torque rankings than helical gears, helical designs have smoother operation, less sound, and higher stiffness, making helical planetary gearboxes the favored gearbox for servo applications.
When a gearbox is put into the drivetrain, the rotational quickness delivered from the engine to the driven element is reduced by the amount of the gear ratio, which can allow the system to make better utilization of the servo motor’s speed-torque characteristics. Planetary gearboxes are able to accept very high input speeds and offer speed reduction of up to 10:1 for standard styles, with high-speed styles providing gear ratios (and, therefore, rate reduction) of 100:1 or higher.
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 frequently lubricated with grease. In any case – grease or essential oil lubrication – planetary gearboxes 
are often lubricated for the life 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 effect on the inertia of the load. The load inertia, which is usually reflected to the electric motor, is reduced by the square of the apparatus ratio. So even a relatively small gear reduction can have a significant effect on the inertia ratio.
A right angle planetary gearbox with output shaft combines the advantages of a compact correct angle gearbox and those of a typical planetary gearbox.
With its versatile mounting options, our right angle gearboxes offer intelligent drive solutions with a compact machine concept. The result shaft gives right angle planetary gearboxes the benefit of a proven and reliable component for the right angle transmission of torque and acceleration.
