The gear boxes are constructed with stainless, except from the input flanges which are constructed of anodized aluminum. Protection class IP65 is standard – IP67 available as choice – which is acheived using a patented insight sealing and a patented result sealing system.
Standard backlash is just 5 respectively 7 arc-minute (1 resp. 2 stages), reduced backlash is merely 3 / 5 arc-min (option) and finally micro backlash is only one third1 / 3 arc-min (option).
This implies that the actual backlash at a particular load is a lot LOWER in an APEX gear box than in any other planetary gear box in the marketplace.
Gearboxes provide torque multiplication, speed reduction, 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 all these requirements while providing relatively lengthy operating life with low maintenance requirements: the planetary gearbox.
A planetary gearbox includes multiple planetary gears that revolve around a central sun equipment while engaging with an internal gear and rotating by themselves axes. The constant engagement of the planetary gears means the strain is shared by multiple 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 also require very precise 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 higher torque rankings than helical gears, helical designs have smoother operation, less noise, and higher stiffness, making helical planetary gearboxes the preferred gearbox for servo applications.
When a gearbox is put into the drivetrain, the rotational speed 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 use of the servo motor’s speed-torque characteristics. Planetary gearboxes can accept high input speeds and provide speed planetary gearbox for servo motor reduction of up to 10:1 for standard styles, with high-speed styles providing gear ratios (and, therefore, acceleration reduction) of 100:1 or more.
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 often lubricated with grease. In any case – grease or oil lubrication – planetary gearboxes are often lubricated for the life of the gearbox by the manufacturer, which eliminates maintenance for the end user.
The most important benefit of using a gearbox in a servo system is arguably its influence on the inertia of the load. The strain inertia, which can be reflected to the electric motor, is decreased by the square of the gear ratio. So a good relatively small gear decrease can have a substantial effect on the inertia ratio.
The right angle planetary gearbox with output shaft combines the benefits of a compact correct angle gearbox and those of a typical planetary gearbox.
With its versatile installation options, our right angle gearboxes offer intelligent drive solutions with a compact machine concept. The result shaft gives right angle planetary gearboxes the advantage of a proven and dependable component for the right angle tranny of torque and swiftness.
