The equipment boxes are constructed with stainless steel, except from the insight flanges which are constructed of anodized aluminum. Protection class IP65 is standard – IP67 offered as option – 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 just 3 / 5 arc-min (option) and finally micro backlash is only one third1 / 3 arc-min (option).
This means that the actual backlash at a specific load is MUCH Low in an APEX gear box than in any other planetary gear box available.
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 type of gearbox meets each one of these requirements while providing relatively long operating life with low maintenance requirements: the planetary gearbox.
A planetary gearbox includes multiple planetary gears that revolve around a central sunlight equipment while engaging with an interior gear and rotating on their own axes. The continuous engagement of the planetary gears means the load is usually shared by multiple tooth, allowing planetary styles 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 also require very precise positioning, and planetary gearboxes are designed and manufactured to have low backlash, with less than 1-2 arcmin in some cases.
Planetary gearboxes can use spur or helical gears. While spur gears can possess higher torque rankings than helical gears, helical styles have smoother operation, 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 acceleration delivered from the engine to the driven component is reduced by the quantity of the gear 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 reduced amount of up to 10:1 for standard styles, with high-speed designs providing equipment ratios (and, therefore, swiftness reduction) of 100:1 or higher.
Planetary gearboxes could 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 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 benefit of utilizing a gearbox in a servo system is arguably its effect on the inertia of the strain. The strain inertia, which can be reflected to the electric motor, is reduced by the square of the apparatus ratio. So a good 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 right angle gearbox and the ones of a planetary gearbox for servo motor 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 right angle transmitting of torque and velocity.
