The equipment boxes are made of stainless steel, except from the input flanges which are constructed of anodized aluminum. Safety class IP65 is regular – IP67 offered as option – which is acheived utilizing a patented insight sealing and a patented result sealing system.
Standard backlash is just 5 respectively 7 arc-minute (1 resp. 2 levels), reduced backlash is just 3 / 5 arc-min (option) and lastly micro backlash is 1 / 31 / 3 arc-min (option).
This implies that the actual backlash at a certain load is a lot LOWER in an APEX gear box than in any other planetary gear box available.
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 all these requirements while providing relatively lengthy operating life with low maintenance requirements: the planetary gearbox.
A planetary gearbox contains multiple planetary gears that revolve around a central sun equipment while engaging with an interior gear and rotating by themselves axes. The constant engagement of the planetary gears means the load can be 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 ideal 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 are designed and manufactured to have low backlash, with less than 1-2 arcmin in some instances.
Planetary gearboxes may use spur or planetary gearbox for servo motor helical gears. While spur gears can have got higher torque rankings than helical gears, helical designs have smoother operation, much less sound, and higher stiffness, making helical planetary gearboxes the favored gearbox for servo applications.
Whenever a gearbox is put into the drivetrain, the rotational swiftness delivered from the electric motor to the driven element is reduced by the amount of the equipment ratio, which can allow the system to make better usage of the servo motor’s speed-torque characteristics. Planetary gearboxes have the ability to accept very high input speeds and offer speed reduced amount of up to 10:1 for standard styles, with high-speed designs providing equipment ratios (and, therefore, swiftness reduction) of 100:1 or more.
Planetary gearboxes could 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 often lubricated with grease. In either case – grease or essential 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 utilizing a gearbox in a servo system is arguably its influence on the inertia of the strain. The strain inertia, which is certainly reflected to the engine, is reduced by the square of the gear 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 right angle gearbox and the ones 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 right angle planetary gearboxes the advantage of a proven and dependable component for the right angle transmitting of torque and acceleration.
