The gear boxes are made from stainless steel, except from the insight flanges which are made of anodized aluminum. Security class IP65 is regular – IP67 obtainable as option – which is acheived using a patented input sealing and a patented output sealing system.
Standard backlash is merely 5 respectively 7 arc-minute (1 resp. 2 stages), reduced backlash is just 3 / 5 arc-min (option) and lastly micro backlash is 1 / 31 / 3 arc-min (option).
This means that the actual backlash at a specific load is a lot Low in an APEX gear box than in virtually any other planetary gear box in the marketplace.
Gearboxes provide torque multiplication, speed decrease, 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 type of gearbox meets all these requirements while providing relatively lengthy operating life with zero-maintenance requirements: the planetary gearbox.
A planetary gearbox contains 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 can be shared by multiple the teeth, allowing planetary designs to transmit high torque loads.
This load sharing among teeth also gives planetary gearboxes high torsional stiffness, making them perfect for processes that involve frequent start-stop motions or changes in rotational direction, which are normal characteristics of servo applications. Most servo applications also require very exact positioning, and planetary gearboxes are designed and manufactured to possess 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 sound, and higher stiffness, producing helical planetary gearboxes the preferred gearbox for servo applications.
Whenever a gearbox is put into the drivetrain, the rotational quickness delivered from the electric motor to the driven element is reduced by the quantity of the gear ratio, which can allow the program to make better usage of the servo motor’s speed-torque characteristics. Planetary gearboxes are able to planetary gearbox for servo motor accept high input speeds and provide speed reduced amount of up to 10:1 for standard designs, with high-speed styles providing gear ratios (and, therefore, acceleration reduction) of 100:1 or more.
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 either case – grease or essential oil lubrication – planetary gearboxes are often lubricated for the life of the gearbox by the manufacturer, 
which eliminates maintenance for the end user.
The most important advantage of utilizing a gearbox in a servo system is arguably its effect on the inertia of the load. The load inertia, which can be reflected to the engine, is reduced by the square of the apparatus ratio. So a good relatively small gear reduction can have a significant effect on the inertia ratio.
The right angle planetary gearbox with output shaft combines the benefits of a compact correct angle gearbox and the ones of a typical planetary gearbox.
With its versatile mounting options, our right angle gearboxes provide intelligent drive solutions with a compact 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 swiftness.
