The gear boxes are made from stainless, except from the insight flanges which are made of anodized aluminum. Protection class IP65 is standard – IP67 available as option – which is acheived utilizing a patented insight sealing and a patented result sealing system.
Standard backlash is just 5 respectively 7 arc-minute (1 resp. 2 levels), reduced backlash is merely 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 specific load is a lot LOWER in an APEX gear box than in any other planetary gear box available.
Gearboxes provide torque multiplication, speed reduction, 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 all these criteria while providing relatively lengthy operating life with zero-maintenance requirements: the planetary gearbox.
A planetary gearbox consists of multiple planetary gears that revolve around a central sunlight equipment while engaging with an internal gear and rotating by themselves axes. The continuous engagement of the planetary gears means the strain is certainly 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 ideal 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 precise positioning, and planetary gearboxes were created and manufactured to have low backlash, with less than 1-2 arcmin in some instances.
Planetary gearboxes may 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 preferred gearbox for servo applications.
Whenever a gearbox is added to the drivetrain, the rotational swiftness delivered from the motor to the driven element is reduced by the quantity of the equipment ratio, that may allow the system to make better utilization of the servo motor’s speed-torque characteristics. Planetary gearboxes can accept very high input speeds and provide speed reduction of up to 10:1 for standard designs, with high-speed designs providing equipment ratios (and, therefore, quickness reduction) of 100:1 or more.
Planetary gearboxes can 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 essential oil lubrication – planetary gearboxes are often lubricated for the life span of the gearbox by the product manufacturer, which eliminates maintenance for the end user.
The most important benefit of utilizing a gearbox in a servo system is arguably its effect on the inertia of the load. The strain inertia, which can be reflected to the motor, is reduced by the square of the apparatus ratio. So even a relatively small gear decrease can have a substantial effect on the inertia ratio.
A right angle planetary gearbox with output shaft planetary gearbox for servo motor combines the advantages of a compact right angle gearbox and those of a typical planetary gearbox.

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