The equipment boxes are made of stainless steel, except from the input flanges which are constructed of anodized aluminum. Protection class IP65 is standard – IP67 offered as option – which is acheived using a patented insight 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 finally micro backlash is only 1 / 31 / 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 out there.
Gearboxes provide torque multiplication, speed decrease, 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 planetary gearbox for servo motor gearbox meets each one of these requirements while providing relatively lengthy operating life with zero-maintenance requirements: the planetary gearbox.
A planetary gearbox includes multiple planetary gears that revolve around a central sunlight gear while engaging with an internal gear and rotating by themselves axes. The continuous engagement of the planetary gears means the load can be shared by multiple teeth, allowing planetary designs 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 are designed and manufactured to possess low backlash, with as little as 1-2 arcmin in some instances.
Planetary gearboxes may use spur or helical gears. While spur gears can have got higher torque rankings than helical gears, helical designs have smoother operation, much less noise, and higher stiffness, making helical planetary gearboxes the favored gearbox for servo applications.
When a gearbox is put into the drivetrain, the rotational swiftness delivered from the motor to the driven element is reduced by the amount of the equipment ratio, that may allow the system to make better use 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 styles providing equipment ratios (and, therefore, speed 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 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 benefit of utilizing a gearbox in a servo system is arguably its effect on the inertia of the strain. The strain inertia, which is reflected to the electric motor, is decreased by the square of the apparatus ratio. So a good relatively small gear reduction can have a significant 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 conventional 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 rate.
