The equipment boxes are constructed with stainless, except from the input flanges which are constructed of anodized aluminum. Protection class IP65 is standard – IP67 offered as option – which is planetary gearbox for servo motor acheived utilizing a patented insight sealing and a patented result sealing system.
Standard backlash is just 5 respectively 7 arc-minute (1 resp. 2 phases), reduced backlash is merely 3 / 5 arc-min (choice) and finally micro backlash is only 1 / 31 / 3 arc-min (option).
This implies that the actual backlash at a particular load is MUCH LOWER in an APEX gear box than in any other planetary gear box out there.
Gearboxes provide torque multiplication, speed decrease, 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 kind of gearbox meets each one of these criteria while providing relatively long operating life with zero-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 by themselves axes. The continuous engagement of the planetary gears means the load is shared by multiple teeth, 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 additionally require very specific positioning, and planetary gearboxes were created and manufactured to have low backlash, with as little as 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 sound, and higher stiffness, making helical planetary gearboxes the preferred gearbox for servo applications.
Whenever a gearbox is added to the drivetrain, the rotational rate delivered from the motor to the driven element is reduced by the amount of the equipment ratio, that may allow the system to make better utilization of the servo motor’s speed-torque characteristics. Planetary gearboxes have the ability to accept very high input speeds and offer speed reduction of up to 10:1 for standard styles, with high-speed styles providing gear ratios (and, therefore, quickness reduction) of 100:1 or higher.
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 any case – grease or oil lubrication – planetary gearboxes are often lubricated for the life span 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 effect on the inertia of the load. The strain inertia, which is reflected to the electric motor, is decreased by the sq . of the gear ratio. So even a relatively small gear decrease can have a substantial influence on the inertia ratio.
