planetary gearbox for servo motor

The gear boxes are made from stainless, except from the input flanges which are made of anodized aluminum. Security class IP65 is regular – IP67 available as choice – which is acheived utilizing a patented input sealing and a patented result sealing system.
Standard backlash is just 5 respectively 7 arc-minute (1 resp. 2 levels), reduced backlash is merely 3 / 5 arc-min (option) and finally micro backlash is only 1 / 31 / 3 arc-min (option).
This means 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 available.
Gearboxes provide torque multiplication, speed decrease, and inertia matching for motor-driven systems. Servo systems, particularly, 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 requirements 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 sunlight gear while engaging with an interior gear and rotating on their own axes. The constant engagement of the planetary gears means the strain is usually shared by multiple tooth, allowing planetary styles to transmit high torque loads.
This load sharing among teeth also gives planetary gearboxes high torsional stiffness, making them perfect for processes that involve frequent start-stop motions or changes in rotational direction, which are normal planetary gearbox for servo motor characteristics of servo applications. Most servo applications also require very precise positioning, and planetary gearboxes are designed and manufactured to possess 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 designs have smoother operation, much less noise, and higher stiffness, making helical planetary gearboxes the favored gearbox for servo applications.
When a gearbox is added to the drivetrain, the rotational swiftness delivered from the engine to the driven component is reduced by the quantity of the equipment ratio, which can allow the program to make better use 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 styles, with high-speed designs providing gear ratios (and, therefore, velocity reduction) of 100:1 or higher.
Planetary gearboxes could 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 product manufacturer, which eliminates maintenance for the end user.
The most important advantage of utilizing 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 reduced by the square of the gear ratio. So a good relatively small gear decrease can have a substantial influence on the inertia ratio.
A right angle planetary gearbox with output shaft combines the advantages of a compact right angle gearbox and the ones of a typical planetary gearbox.

With its versatile installation options, our right angle gearboxes offer intelligent drive solutions with a compact machine concept. The output shaft gives correct angle planetary gearboxes the advantage of a proven and reliable component for the right angle tranny of torque and velocity.
