The equipment boxes are made of stainless steel, except from the insight flanges which are made of anodized aluminum. Security class IP65 is standard – IP67 obtainable as option – which is acheived utilizing a patented insight sealing and a patented result sealing system.
Standard backlash is just 5 respectively 7 planetary gearbox for servo motor arc-minute (1 resp. 2 levels), reduced backlash is just 3 / 5 arc-min (choice) and finally micro backlash is only 1 / 31 / 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 out there.
Gearboxes provide torque multiplication, speed decrease, and inertia matching for motor-driven systems. Servo systems, particularly, 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 requirements while providing relatively long operating life with low maintenance requirements: the planetary gearbox.
A planetary gearbox contains multiple planetary gears that revolve around a central sun gear while engaging with an internal gear and rotating on their own axes. The constant engagement of the planetary gears means the strain is certainly 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 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 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, making helical planetary gearboxes the preferred gearbox for servo applications.
Whenever a gearbox is added to the drivetrain, the rotational quickness delivered from 
the engine to the driven component is reduced by the quantity of the equipment ratio, which can allow the program to make better use of the servo motor’s speed-torque characteristics. Planetary gearboxes can easily accept high input speeds and provide speed reduced amount of up to 10:1 for standard designs, with high-speed styles providing gear ratios (and, therefore, velocity 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 either case – grease or essential oil lubrication – planetary gearboxes tend to be lubricated for the life of the gearbox by the product 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 strain inertia, which is reflected to the engine, is decreased by the sq . 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 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 correct angle planetary gearboxes the benefit of a proven and reliable component for the right angle tranny of torque and speed.
