The gear boxes are made from stainless, except from the input flanges which are constructed of anodized aluminum. Safety class IP65 is regular – IP67 offered as option – which is acheived utilizing a patented input sealing and a patented result sealing system.
Standard backlash is merely 5 respectively 7 arc-minute (1 resp. 2 stages), reduced backlash is just 3 / 5 arc-min (choice) and finally micro backlash is 1 / 31 / 3 arc-min (option).
This implies that the actual backlash at a particular load is a lot LOWER in an APEX gear box than in virtually any other planetary gear box on the market.
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 kind of gearbox meets each one of these requirements 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 sunlight gear while engaging with an internal gear and rotating on their own axes. The constant engagement of the planetary gears means the strain is certainly shared by multiple the teeth, allowing planetary designs to transmit high torque loads.
This load sharing among teeth also gives planetary gearboxes high torsional stiffness, making them perfect for processes that planetary gearbox for servo motor involve frequent start-stop motions or changes in rotational direction, which are common 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 can use spur or helical gears. While spur gears can have higher torque rankings than helical gears, helical styles have smoother operation, less noise, and higher stiffness, producing helical planetary gearboxes the preferred gearbox for servo applications.
When a gearbox is put into the drivetrain, the rotational velocity delivered from the electric motor to the driven component is reduced by the quantity of the gear ratio, that may 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 reduced amount of up to 10:1 for standard designs, with high-speed designs providing gear ratios (and, therefore, rate reduction) of 100:1 or more.
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 often lubricated with grease. In either case – grease or essential oil lubrication – planetary gearboxes tend to be lubricated for the life of the gearbox by the manufacturer, which eliminates maintenance for the finish user.
The most important benefit of using a gearbox in a servo system is arguably its influence on the inertia of the load. The load inertia, which is certainly reflected to the electric motor, is decreased by the sq . 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 advantages 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 compact machine concept. The result shaft gives right angle planetary gearboxes the benefit of a proven and reliable component for the right angle transmitting of torque and swiftness.
