The gear boxes are constructed with stainless, 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 output sealing system.
Standard backlash is merely 5 respectively 7 arc-minute (1 resp. 2 phases), reduced backlash is merely 3 / 5 arc-min (choice) and lastly micro backlash is only one third1 / 3 arc-min (option).
This means that the actual backlash at a specific load is MUCH LOWER in an APEX gear box than in virtually any other 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 merely high torque with low added inertia, but also high precision and stiffness. One kind 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 sunlight gear while engaging with an internal gear and rotating on their own axes. The continuous engagement of the planetary gears means the strain can be shared by multiple tooth, allowing planetary designs 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 also require very exact positioning, and planetary gearboxes were created and manufactured to possess low backlash, with as little as 1-2 arcmin in some instances.
Planetary gearboxes may use spur or helical gears. While spur gears can have got higher torque ratings than helical gears, helical designs have smoother operation, less noise, and higher stiffness, producing helical planetary gearboxes the favored 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 use of the servo motor’s speed-torque characteristics. Planetary gearboxes can accept high input speeds and offer speed reduction of up to 10:1 for standard styles, with high-speed styles providing gear ratios (and, therefore, swiftness 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 planetary gearbox for servo motor frequently lubricated with grease. In either 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 benefit of utilizing a gearbox in a servo system is arguably its influence on the inertia of the strain. The strain inertia, which is reflected to the engine, is decreased by the sq . of the apparatus ratio. So even a relatively small gear reduction can have a substantial influence on the inertia ratio.
A right angle planetary gearbox with output shaft combines the benefits of a compact correct angle gearbox and those of a typical planetary gearbox.
With its versatile mounting options, our right angle gearboxes offer intelligent drive solutions with a concise machine concept. The output shaft gives right angle planetary gearboxes the benefit of a proven and reliable component for the right angle transmitting of torque and velocity.
