The gear boxes are constructed with stainless, except from the input flanges which are made of anodized aluminum. Protection class IP65 is standard – IP67 available as option – which is acheived using a patented insight sealing and a patented output sealing system.
Standard backlash is merely 5 respectively 7 arc-minute (1 resp. 2 levels), reduced backlash is merely 3 / 5 arc-min (option) and finally micro backlash is only 1 / 31 / 3 arc-min (option).
This implies that the actual backlash at a specific load is a lot Reduced an APEX gear box than in any other planetary gear box on the market.
Gearboxes provide torque multiplication, speed decrease, and inertia matching for motor-driven systems. Servo planetary gearbox for servo motor systems, specifically, require gearboxes that can 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 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 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 common 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 instances.
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, much less sound, and higher stiffness, producing helical planetary gearboxes the preferred gearbox for servo applications.
When a gearbox is put into 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 have the ability to accept high input speeds and offer speed reduction of up to 10:1 for standard designs, with high-speed designs providing equipment ratios (and, therefore, velocity reduction) of 100:1 or higher.
Planetary gearboxes can be lubricated with either grease or oil, although a planetary gearbox for servo use (sometimes known as a “servo rated” or “servo” gearbox) is frequently lubricated with grease. In either 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 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 engine, is decreased by the square of the gear ratio. So a good 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 right 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 dependable component for the right angle tranny of torque and speed.
