The gear boxes are constructed with stainless steel, except from the input flanges which are constructed of anodized aluminum. Safety class IP65 is standard – IP67 offered as choice – which is acheived using a patented insight sealing and a patented output sealing system.
Standard backlash is just 5 respectively 7 arc-minute (1 resp. 2 phases), reduced backlash is merely 3 / 5 arc-min (option) and lastly micro backlash is one third1 / 3 arc-min (option).
This implies that the actual backlash at a certain load is a lot Reduced an APEX gear box than in virtually any other planetary gear box in the marketplace.
Gearboxes provide torque multiplication, speed decrease, and inertia matching for motor-driven systems. Servo systems, specifically, require gearboxes that may supply not merely high torque with low added inertia, but also high precision and stiffness. One kind of gearbox meets each one of 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 sunlight equipment while engaging with an internal gear and rotating on their own axes. The continuous 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 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 possess low backlash, with less than 1-2 arcmin in some instances.
Planetary gearboxes can use spur or helical gears. While spur gears can possess higher torque rankings than helical gears, helical styles have smoother operation, less noise, and higher stiffness, producing helical planetary gearboxes the favored 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 amount of the equipment ratio, which can allow the program to make better usage of the servo motor’s speed-torque characteristics. Planetary gearboxes have the ability to accept high input speeds and offer speed reduced amount of up to 10:1 for standard styles, with high-speed planetary gearbox for servo motor designs providing gear ratios (and, therefore, quickness 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 often 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 benefit of utilizing a gearbox in a servo system is arguably its influence on the inertia of the load. The strain inertia, which is reflected to the motor, is reduced by the square of the apparatus ratio. So a good 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 those of a typical planetary gearbox.

With its versatile mounting options, our right angle gearboxes offer intelligent drive solutions with a concise machine concept. The output shaft gives correct angle planetary gearboxes the advantage of a proven and reliable component for the proper angle tranny of torque and rate.
