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 available as option – which is acheived utilizing a patented input sealing and a patented output sealing system.
Standard backlash is merely 5 respectively 7 arc-minute (1 resp. 2 phases), 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 specific load is MUCH Low 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 can supply not only high torque with low added inertia, but also high precision and stiffness. One type of gearbox meets each one of these criteria while providing relatively lengthy operating life with low maintenance requirements: the planetary gearbox.
A planetary gearbox includes multiple planetary gears that revolve around a central sunlight equipment while engaging with an interior gear and rotating on their own 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 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 exact positioning, and planetary gearboxes were created 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 possess higher torque ratings than helical gears, helical designs have smoother operation, less noise, and higher stiffness, making helical planetary gearboxes the preferred gearbox for servo applications.
Whenever a gearbox is added to the drivetrain, the rotational velocity delivered from the engine to the driven component is reduced by the amount of the gear ratio, that may allow the system to make better usage of the servo motor’s speed-torque characteristics. Planetary gearboxes can easily accept high input speeds and provide 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 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 often lubricated with grease. In any 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 using a gearbox in a servo system is arguably its influence on the inertia of the load. The load inertia, which is usually reflected to the electric motor, is decreased by the square of the apparatus ratio. So a good relatively small gear reduction can have a substantial effect on the inertia ratio.
The 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 planetary gearbox for servo motor solutions with a concise machine concept. The output shaft gives right angle planetary gearboxes the advantage of a proven and dependable component for the proper angle tranny of torque and quickness.
