The gear boxes are made from stainless steel, except from the insight flanges which are made of anodized aluminum. Safety class IP65 is regular – IP67 available as choice – which is acheived utilizing 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 just 3 / 5 arc-min (option) and lastly micro backlash is only one third1 / 3 arc-min (option).
This means that the actual backlash at a certain load is MUCH Reduced an APEX gear box than in virtually 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 may supply not only high torque with low added inertia, but also high precision and stiffness. One type of gearbox meets each one of these requirements while providing relatively lengthy operating life with low maintenance requirements: the planetary gearbox.
A planetary gearbox consists of multiple planetary gears that revolve around a central sun gear while engaging with an internal gear and rotating by themselves axes. The constant engagement of the planetary gears means the strain is definitely 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 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 precise positioning, and planetary gearboxes were created and manufactured to have low backlash, with less than 1-2 arcmin in some cases.
Planetary gearboxes can use spur or helical gears. While spur gears can have higher torque ratings than helical gears, helical designs have smoother operation, less noise, and higher stiffness, producing helical planetary gearboxes the preferred gearbox for servo applications.
When a gearbox is added to the drivetrain, the rotational swiftness delivered from the motor to the driven element is reduced by the quantity of the gear ratio, that may allow the system to make better usage of the servo motor’s speed-torque characteristics. Planetary gearboxes can easily accept very high input speeds and provide speed reduction of up to 10:1 for standard designs, with high-speed designs providing gear ratios (and, therefore, quickness reduction) of 100:1 or higher.
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 are often lubricated for the life span of the gearbox by the product manufacturer, which eliminates maintenance for the finish user.
The most important benefit of using a gearbox in a servo system is arguably its influence on the inertia of the strain. The load inertia, which can be reflected to the motor, is decreased by the sq . of the gear ratio. So a good relatively small gear decrease can have a significant influence on the inertia ratio.
A right angle planetary gearbox with output shaft combines the advantages of a compact right angle gearbox and the ones of a conventional planetary gearbox.

With its versatile installation options, our right angle gearboxes offer intelligent drive solutions with a concise machine concept. The output shaft gives right angle planetary gearboxes the benefit of a proven and reliable component for the right angle transmitting of torque and velocity.
