planetary gearbox for servo motor

The equipment boxes are made from stainless steel, except from the input flanges which are made of anodized aluminum. Security class IP65 is standard – IP67 offered as choice – which is acheived using 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 (option) and lastly micro backlash is only one third1 / 3 arc-min (option).
This implies that the actual backlash at a particular load is MUCH Low in an APEX gear box than in any other planetary gearbox for servo motor planetary gear box on the market.
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 type of gearbox meets each one of these requirements while providing relatively long operating life with zero-maintenance requirements: the planetary gearbox.
A planetary gearbox contains 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 ideal for processes that involve frequent start-stop motions or changes in rotational direction, which are common characteristics of servo applications. Most servo applications additionally require very exact positioning, and planetary gearboxes were created and manufactured to possess 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, much less noise, and higher stiffness, producing helical planetary gearboxes the preferred gearbox for servo applications.
Whenever a gearbox is added to the drivetrain, the rotational rate delivered from the electric motor to the driven component is reduced by the quantity of the gear ratio, which can allow the system to make better use of the servo motor’s speed-torque characteristics. Planetary gearboxes can accept very high input speeds and offer speed reduction of up to 10:1 for standard styles, with high-speed designs providing equipment ratios (and, therefore, velocity 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 frequently 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 strain. The load inertia, which is usually reflected to the motor, is decreased by the square of the apparatus ratio. So even a relatively small gear reduction can have a significant effect on the inertia ratio.
A right angle planetary gearbox with output shaft combines the advantages of a compact correct angle gearbox and those of a conventional planetary gearbox.

With its versatile mounting options, our right angle gearboxes offer intelligent drive solutions with a concise machine concept. The output shaft gives correct angle planetary gearboxes the benefit of a proven and reliable component for the proper angle tranny of torque and swiftness.
