The gear boxes are made of stainless steel, 
except from the insight flanges which are made of anodized aluminum. Safety class IP65 is regular – IP67 obtainable as option – which is acheived utilizing a patented insight sealing and a patented result sealing system.
Standard backlash is just 5 respectively 7 arc-minute (1 resp. 2 levels), reduced backlash is merely 3 / 5 arc-min (choice) and finally micro backlash is one third1 / 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 gearbox for servo motor 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 merely high torque with low added inertia, but also high precision and stiffness. One type of gearbox meets all these requirements while providing relatively long operating life with low maintenance requirements: the planetary gearbox.
A planetary gearbox consists of multiple planetary gears that revolve around a central sun equipment while engaging with an internal gear and rotating on their own axes. The continuous engagement of the planetary gears means the strain is certainly 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 well suited 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 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 may use spur or helical gears. While spur gears can have higher torque ratings than helical gears, helical styles have smoother operation, much less sound, and higher stiffness, producing helical planetary gearboxes the preferred gearbox for servo applications.
Whenever a gearbox is put into the drivetrain, the rotational swiftness delivered from the electric motor to the driven element is reduced by the amount of the equipment ratio, which can allow the system to make better usage of the servo motor’s speed-torque characteristics. Planetary gearboxes have the ability to accept very high input speeds and provide speed reduction of up to 10:1 for standard designs, 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 (sometimes known as a “servo rated” or “servo” gearbox) is frequently lubricated with grease. In any case – grease or oil lubrication – planetary gearboxes are often lubricated for the life of the gearbox by the 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 definitely reflected to the motor, is reduced by the square of the apparatus ratio. So even a relatively small gear reduction 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 those of a typical planetary gearbox.
With its versatile installation options, our right angle gearboxes provide intelligent drive solutions with a compact machine concept. The output shaft gives right angle planetary gearboxes the benefit of a proven and dependable component for the right angle tranny of torque and speed.
