The equipment boxes are made of stainless steel, except from the insight flanges which are made of anodized aluminum. Security class IP65 is regular – IP67 obtainable as choice – which is acheived using a patented input sealing and a patented output sealing system.
Standard backlash is just 5 respectively 7 arc-minute (1 resp. 2 stages), reduced backlash is just 3 / 5 arc-min (choice) and lastly micro backlash is one third1 / 3 arc-min (option).
This means that the actual backlash at a certain load is MUCH Low in an APEX gear box than in virtually any other planetary gearbox for servo motor Planetary gear box out there.
Gearboxes provide torque multiplication, speed decrease, and inertia matching for motor-driven systems. Servo systems, particularly, require gearboxes that may 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 contains multiple planetary gears that revolve around a central sun gear while engaging with an interior gear and rotating on their own axes. The constant engagement of the planetary gears means the load is definitely 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 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 additionally require very specific positioning, and planetary gearboxes are designed 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 rankings than helical gears, helical styles have smoother operation, less sound, and higher stiffness, making helical planetary gearboxes the favored gearbox for servo applications.
Whenever a gearbox is added to the drivetrain, the rotational speed delivered from the electric motor to the driven component is reduced by the amount of the gear ratio, which can allow the program to make better usage of the servo motor’s speed-torque characteristics. Planetary gearboxes can easily accept high input speeds and provide speed reduced amount of up to 10:1 for standard styles, with high-speed styles providing gear ratios (and, therefore, acceleration reduction) of 100:1 or more.
Planetary gearboxes could be lubricated with either grease or oil, although a planetary gearbox for servo use (sometimes known as a “servo rated” or “servo” gearbox) is often lubricated with grease. In any case – grease or 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 advantage of using a gearbox in a servo system is arguably its influence on the inertia of the strain. The load inertia, which is reflected to the electric motor, is reduced by the sq . of the apparatus ratio. So even a relatively small gear reduction can have a significant effect on the inertia ratio.
