The equipment boxes are made of stainless, except from the input flanges which are constructed of anodized aluminum. Safety class IP65 is regular – IP67 obtainable as choice – which is acheived utilizing 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 (choice) and lastly micro backlash is only 1 / 31 / 3 arc-min (option).
This implies that the actual backlash at a specific load is a lot Low in an APEX gear box than in any other planetary gear box on the market.
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 each one of these criteria while providing relatively long operating life with zero-maintenance requirements: the planetary gearbox.
A planetary gearbox contains multiple planetary gears that revolve around a central sun gear while engaging with an interior gear and rotating by themselves axes. The constant engagement of the planetary gears means the load is certainly 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 also require very specific positioning, and planetary gearboxes were created and manufactured to have low backlash, with less than 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, much less noise, and higher stiffness, making helical planetary gearboxes the favored gearbox for servo applications.
When a gearbox is put into the drivetrain, the rotational velocity delivered from the engine to the driven element is reduced by the quantity of the equipment ratio, which can allow the program to make better usage of the servo motor’s speed-torque characteristics. Planetary gearboxes are able to accept high input speeds and provide speed reduction of up to 10:1 for standard designs, 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 frequently 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 end user.
The most important advantage of using a gearbox in a servo planetary gearbox for servo motor system is arguably its influence on the inertia of the strain. The strain inertia, which is certainly reflected to the electric motor, is decreased by the square of the apparatus ratio. So even a relatively small gear decrease can have a significant influence 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 typical planetary gearbox.
With its versatile installation options, our right angle gearboxes provide intelligent drive solutions with a concise machine concept. The output shaft gives correct angle planetary gearboxes the benefit of a proven and reliable component for the proper angle transmission of torque and speed.
