The gear boxes are constructed with stainless steel, except from the input flanges which are constructed of anodized aluminum. Security class IP65 is standard – IP67 offered as choice – which is acheived using a patented input sealing and a patented result sealing system.
Standard backlash is merely 5 respectively 7 arc-minute (1 resp. 2 levels), reduced backlash is merely 3 / 5 arc-min (option) and finally micro backlash is 1 / 31 / 3 arc-min (option).
This implies that the actual backlash at a certain load is a lot Low in an APEX gear box than in any other planetary gear box available.
Gearboxes provide torque multiplication, speed decrease, 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 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 gear while engaging with an internal gear and rotating on their own axes. The constant engagement of the planetary gears means the load can be shared by multiple teeth, allowing planetary styles 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 common characteristics of servo applications. Most servo applications additionally require very specific positioning, and planetary gearboxes were created and manufactured to have 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 higher torque rankings than helical gears, helical styles have smoother operation, much less sound, and higher stiffness, making helical planetary gearboxes the favored gearbox for servo applications.
When a gearbox is added to the drivetrain, the rotational velocity delivered from the motor to the driven element is reduced by the amount of the equipment ratio, which can allow the system to make better use of the servo motor’s speed-torque characteristics. Planetary gearboxes can accept very high input speeds and provide speed reduction of up to 10:1 for standard styles, with high-speed designs providing gear ratios (and, therefore, speed reduction) of 100:1 or more.
Planetary gearboxes can be lubricated with either grease or oil, although a planetary gearbox for servo use (planetary gearbox for servo motor 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 span of the gearbox by the manufacturer, which eliminates maintenance for the end user.
The most important benefit of using a gearbox in a servo system is arguably its effect on the inertia of the load. The load inertia, which is certainly reflected to the motor, is decreased by the sq . of the apparatus ratio. So a good relatively small gear reduction can have a significant influence on the inertia ratio.
The right angle planetary gearbox with output shaft combines the benefits of a compact right angle gearbox and those of a typical planetary gearbox.
With its versatile installation options, our right angle gearboxes offer intelligent drive solutions with a compact machine concept. The output shaft gives right angle planetary gearboxes the advantage of a proven and dependable component for the proper angle transmitting of torque and rate.
