The equipment boxes are made of stainless steel, except from the input flanges which are made of anodized aluminum. Protection class IP65 is standard – IP67 obtainable 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), planetary gearbox for servo motor Reduced backlash is just 3 / 5 arc-min (option) and finally micro backlash is 1 / 31 / 3 arc-min (option).
This means that the actual backlash at a specific load is a lot Reduced an APEX gear box than in virtually any other planetary gear box available.
Gearboxes provide torque multiplication, speed reduction, and inertia matching for motor-driven systems. Servo systems, particularly, 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 criteria 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 sun equipment while engaging with an interior gear and rotating by themselves axes. The constant engagement of the planetary gears means the strain is certainly shared by multiple 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 exact positioning, and planetary gearboxes are designed and manufactured to possess low backlash, with less than 1-2 arcmin in 
some instances.
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 noise, and higher stiffness, making helical planetary gearboxes the preferred gearbox for servo applications.
Whenever a gearbox is added to the drivetrain, the rotational speed delivered from the motor to the driven element is reduced by the amount of the gear ratio, which can allow the system to make better utilization of the servo motor’s speed-torque characteristics. Planetary gearboxes can 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, swiftness 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 essential oil lubrication – planetary gearboxes are often lubricated for the life of the gearbox by the product manufacturer, which eliminates maintenance for the finish user.
The most important benefit of utilizing a gearbox in a servo system is arguably its effect on the inertia of the load. The load inertia, which is usually reflected to the electric motor, is decreased by the sq . of the gear ratio. So a good relatively small gear decrease can have a significant influence on the inertia ratio.
