The equipment boxes are made from stainless steel, except from the input flanges which are constructed of anodized aluminum. Protection class IP65 is regular – IP67 offered as option – which is acheived using a patented insight sealing and a patented output sealing system.
Standard backlash is just 5 respectively 7 arc-minute (1 resp. 2 phases), reduced backlash is merely 3 / 5 arc-min (option) and finally micro backlash is only 1 / 31 / 3 arc-min (option).
This implies that the actual backlash at a specific load is MUCH Reduced an APEX gear box than in any other planetary gear box out there.
Gearboxes provide torque multiplication, speed reduction, and inertia matching for motor-driven systems. Servo systems, specifically, require gearboxes that may supply not only 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 low 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 on their own axes. The continuous engagement of the planetary gears means the strain is certainly 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 common characteristics of servo applications. Most servo applications additionally require very precise positioning, and planetary gearboxes were created and manufactured to possess low backlash, with as little as 1-2 arcmin in some cases.
Planetary gearboxes can use spur or helical gears. While spur gears can have got higher torque rankings than helical gears, helical styles have smoother operation, much less sound, and higher stiffness, making helical planetary gearboxes the preferred gearbox for servo applications.
When a gearbox is added to the drivetrain, the rotational acceleration delivered from the motor to the driven element is reduced by the quantity of the equipment ratio, that may allow the system to make better utilization of the servo motor’s speed-torque characteristics. Planetary gearboxes are able to accept high input speeds and offer speed reduced amount of up 
to 10:1 for standard styles, with high-speed styles providing equipment ratios (and, therefore, quickness reduction) of 100:1 or higher.
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 often lubricated with grease. In either case – grease or essential oil lubrication – planetary gearboxes are often lubricated for the life 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 effect on the inertia of the strain. The strain inertia, which can be planetary gearbox for servo motor reflected to the engine, is decreased by the sq . of the gear ratio. So a good relatively small gear reduction can have a significant effect on the inertia ratio.
A 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 installation options, our right angle gearboxes offer intelligent drive solutions with a compact machine concept. The result shaft gives correct angle planetary gearboxes the benefit of a proven and reliable component for the right angle tranny of torque and velocity.
