The gear boxes are constructed with stainless steel, except from the insight flanges which are constructed of anodized aluminum. Safety class IP65 is regular – IP67 available as option – which is acheived utilizing a patented insight sealing and a patented result sealing system.
Standard planetary gearbox for servo motor backlash is just 5 respectively 7 arc-minute (1 resp. 2 stages), reduced backlash is merely 3 / 5 arc-min (choice) and finally micro backlash is one third1 / 3 arc-min (option).
This means that the actual backlash at a specific load is MUCH Reduced an APEX gear box than in any other planetary gear box in the marketplace.
Gearboxes provide torque multiplication, speed reduction, and inertia matching for motor-driven systems. Servo systems, specifically, 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 includes multiple planetary gears that revolve around a central sun equipment while engaging with an internal gear and rotating by themselves axes. The constant engagement of the planetary gears means the load is usually 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 additionally require very exact positioning, and planetary gearboxes are designed and manufactured to have 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 designs have smoother operation, much less noise, 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 engine to the driven element is reduced by the amount of the equipment ratio, that may allow the system to make better usage of the servo motor’s speed-torque characteristics. Planetary gearboxes are able to accept very high input speeds and offer speed reduced amount of up to 10:1 for standard styles, with high-speed designs providing equipment ratios (and, therefore, velocity 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 frequently lubricated with grease. In either case – grease or oil lubrication – planetary gearboxes are often lubricated for the life span of the gearbox by the product manufacturer, which eliminates maintenance for the finish user.
The most important advantage of utilizing a gearbox in a servo system is arguably its effect on the inertia of the load. The load inertia, which is reflected to the engine, is reduced by the sq . of the apparatus ratio. So a good relatively small gear decrease can have a significant influence on the inertia ratio.
A right angle planetary gearbox with output shaft combines the benefits of a compact correct angle gearbox and the ones of a typical planetary gearbox.
With its versatile installation options, our right angle gearboxes provide intelligent drive solutions with a concise machine concept. The result shaft gives correct angle planetary gearboxes the advantage of a proven and dependable component for the right angle transmitting of torque and velocity.
