The gear boxes are constructed with stainless steel, except from the insight flanges which are made of anodized aluminum. Security class IP65 is regular – IP67 offered as choice – 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 just 3 / 5 arc-min (option) and finally micro backlash is only one planetary gearbox for servo motor third1 / 3 arc-min (option).
This implies that the actual backlash at a certain load is MUCH Reduced an APEX gear box than in virtually any other planetary gear box out there.
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 kind of gearbox meets each one of these criteria while providing relatively long operating life with zero-maintenance requirements: the planetary gearbox.
A planetary gearbox contains 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 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 common characteristics of servo applications. Most servo applications additionally require very exact positioning, and planetary gearboxes were created and manufactured to have low backlash, with as little as 1-2 arcmin in some cases.
Planetary gearboxes may use spur or helical gears. While spur gears can have higher torque ratings than helical gears, helical styles have smoother operation, less noise, and higher stiffness, making helical planetary gearboxes the preferred gearbox for servo applications.
Whenever 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 equipment ratio, that may allow the program to make better usage of the servo motor’s speed-torque characteristics. Planetary gearboxes can 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, speed 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 frequently lubricated with grease. In any case – grease or oil lubrication – planetary gearboxes tend to be lubricated for the life span of the gearbox by the product manufacturer, which eliminates maintenance for the finish 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 electric motor, is decreased by the square of the gear ratio. So even a relatively small gear reduction can have a significant effect on the inertia ratio.
The right angle planetary gearbox with output shaft combines the advantages of a compact correct angle gearbox and the ones 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 benefit of a proven and dependable component for the right angle transmitting of torque and rate.
