The gear boxes are made of stainless, except from the input flanges which are constructed of anodized aluminum. Protection class IP65 is regular – IP67 offered as option – which is acheived utilizing a patented input sealing and a patented result sealing system.
Standard backlash is merely 5 respectively 7 arc-minute (1 resp. 2 levels), reduced backlash is merely 3 / 5 arc-min (choice) and lastly micro backlash is only one third1 / 3 arc-min (option).
This means that the actual backlash at a specific load is MUCH Low in an APEX gear box than in virtually any other planetary gear box available.
Gearboxes provide planetary gearbox for servo motor torque multiplication, speed decrease, and inertia matching for motor-driven systems. Servo 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 long operating life with zero-maintenance requirements: the planetary gearbox.
A planetary gearbox contains multiple planetary gears that revolve around a central sun 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 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 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 less than 1-2 arcmin in some instances.
Planetary gearboxes may use spur or helical gears. While spur gears can have higher torque ratings than helical gears, helical designs have smoother operation, much 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 quickness delivered from the engine to the driven component is reduced by the quantity of the equipment ratio, that may allow the system to make better utilization of the servo motor’s speed-torque characteristics. Planetary gearboxes can easily accept very high input speeds and offer speed reduced amount of up to 10:1 for standard designs, with high-speed styles providing gear ratios (and, therefore, speed 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 frequently lubricated with grease. In any case – grease or essential oil lubrication – planetary gearboxes tend to be lubricated for the life span 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 effect on the inertia of the strain. The strain inertia, which is usually reflected to the electric motor, is reduced by the square of the apparatus ratio. So even a relatively small gear reduction can have a substantial influence on the inertia ratio.
A 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 mounting options, our right angle gearboxes provide intelligent drive solutions with a compact machine concept. The result shaft gives correct angle planetary gearboxes the advantage of a proven and reliable component for the right angle transmitting of torque and swiftness.
