The gear boxes are made from stainless, except from the input flanges which are constructed of anodized aluminum. Security class IP65 is regular – IP67 obtainable as choice – which is planetary gearbox for servo motor acheived using a patented input sealing and a patented result sealing system.
Standard backlash is just 5 respectively 7 arc-minute (1 resp. 2 stages), reduced backlash is merely 3 / 5 arc-min (option) and lastly micro backlash is only 1 / 31 / 3 arc-min (option).
This implies that the actual backlash at a particular load is a lot Reduced an APEX gear box than in virtually 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 merely high torque with low added inertia, but also high precision and stiffness. One kind of gearbox meets all these criteria 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 internal gear and rotating on their own axes. The continuous engagement of the planetary gears means the strain is 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 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 specific 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 have higher torque rankings than helical gears, helical styles have smoother operation, much less sound, and higher stiffness, producing helical planetary gearboxes the favored gearbox for servo applications.
When a gearbox is put into the drivetrain, the rotational rate delivered from the motor to the driven element is reduced by the quantity of the gear ratio, that may allow the program to make better use of the servo motor’s speed-torque characteristics. Planetary gearboxes are able to accept high input speeds and offer speed reduction of up to 10:1 for standard designs, with high-speed styles providing gear ratios (and, therefore, rate 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 often 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 end user.
The most important advantage 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 engine, is decreased by the square of the gear ratio. So even a relatively small gear reduction 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 conventional planetary gearbox.
With its versatile installation 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 dependable component for the proper angle transmitting of torque and swiftness.
