The gear boxes are made from stainless, except from the insight flanges which are made of anodized aluminum. Safety class IP65 is regular – IP67 available as choice – which is acheived using a patented input planetary gearbox for servo motor sealing and a patented result sealing system.
Standard backlash is just 5 respectively 7 arc-minute (1 resp. 2 stages), reduced backlash is just 3 / 5 arc-min (option) and lastly micro backlash is one third1 / 3 arc-min (option).
This means that the actual backlash at a particular load is a lot Low in an APEX gear box than in 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 may supply not merely 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 gear while engaging with an interior gear and rotating on their own axes. The constant engagement of the planetary gears means the strain is 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 ideal for processes that involve frequent start-stop motions or changes in rotational direction, which are normal characteristics of servo applications. Most servo applications also require very specific positioning, and planetary gearboxes were created and manufactured to have low backlash, with less than 1-2 arcmin in some cases.
Planetary gearboxes may use spur or helical gears. While spur gears can have higher torque ratings 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 put into the drivetrain, the rotational velocity delivered from the engine to the driven component is reduced by the quantity of the gear ratio, that may allow the system to make better utilization of the servo motor’s speed-torque characteristics. Planetary gearboxes are able to accept high input speeds and offer speed reduced amount of up to 10:1 for standard styles, with high-speed designs providing gear ratios (and, therefore, rate reduction) of 100:1 or higher.
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 often lubricated with grease. In either case – grease or essential oil lubrication – planetary gearboxes tend to be lubricated for the life span of the gearbox by the manufacturer, which eliminates maintenance for the end user.
The most important benefit of using a gearbox in a servo system is arguably its influence on the inertia of the load. The strain inertia, which is definitely reflected to the motor, is reduced by the sq . of the gear ratio. So even a relatively small gear decrease can have a significant effect 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 installation 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 dependable component for the proper angle tranny of torque and speed.
