The gear boxes are constructed with stainless steel, except from the input flanges which are made of anodized aluminum. Protection class IP65 is regular – IP67 available 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), planetary gearbox for servo motor reduced backlash is just 3 / 5 arc-min (option) and lastly micro backlash is only 1 / 31 / 3 arc-min (option).
This means that the actual backlash at a specific load is MUCH Low in an APEX gear box than in 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 may supply not only high torque with low added inertia, but also high precision and stiffness. One kind 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 sunlight gear while engaging with an interior gear and rotating by themselves axes. The constant engagement of the planetary gears means the load is shared by multiple tooth, 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 common characteristics of servo applications. Most servo applications also require very precise positioning, and planetary gearboxes were created and manufactured to possess 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, much less sound, and higher stiffness, producing helical planetary gearboxes the favored gearbox for servo applications.
When a gearbox is added to the drivetrain, the rotational rate delivered from the electric motor to the driven component is reduced by the amount of the gear ratio, that may allow the program to make better utilization of the servo motor’s speed-torque characteristics. Planetary gearboxes can easily accept very high input speeds and provide speed reduced amount of up to 10:1 for standard designs, with high-speed designs providing equipment ratios (and, therefore, rate reduction) of 100:1 or more.
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 any case – grease or oil lubrication – planetary gearboxes are often lubricated for the life span 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 influence on the inertia of the load. The load inertia, which is certainly reflected to the engine, is decreased by the square of the apparatus ratio. So a good relatively small gear reduction can have a substantial effect on the inertia ratio.
The right angle planetary gearbox with output shaft combines the benefits of a compact right angle gearbox and those of a typical planetary gearbox.

With its versatile mounting options, our right angle gearboxes provide intelligent drive solutions with a concise machine concept. The result shaft gives right angle planetary gearboxes the advantage of a proven and dependable component for the proper angle transmission of torque and speed.
