The equipment boxes are made from 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 merely 5 respectively 7 arc-minute (1 resp. 2 phases), reduced backlash is merely 3 / 5 arc-min (choice) and finally micro backlash is 1 / 31 / 3 arc-min (option).
This implies that the actual backlash at a certain load is a lot Low in an APEX gear box than in any other planetary gearbox for servo motor planetary gear box in the marketplace.
Gearboxes provide torque multiplication, speed reduction, and inertia matching for motor-driven systems. Servo systems, particularly, 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 criteria while providing relatively long operating life with zero-maintenance requirements: the planetary gearbox.
A planetary gearbox consists of 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 strain is shared by multiple tooth, 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 normal characteristics of servo applications. Most servo applications additionally require very precise positioning, and planetary gearboxes were created and manufactured to possess low backlash, with less than 1-2 arcmin in some cases.
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 rate delivered from the engine to the driven component is reduced by the quantity 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 high input speeds and provide speed reduction of up to 10:1 for standard designs, with high-speed styles providing equipment 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 referred to 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 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 load. The load inertia, which is reflected to the motor, is decreased by the sq . of the apparatus ratio. So even a relatively small gear decrease can have a substantial influence on the inertia ratio.
A 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 compact machine concept. The result shaft gives right angle planetary gearboxes the benefit of a proven and reliable component for the proper angle transmitting of torque and swiftness.
