The equipment boxes are made from stainless, except from the insight flanges which are made of anodized aluminum. Protection class IP65 is standard – IP67 obtainable as option – which is acheived utilizing a patented insight 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 (choice) and lastly micro backlash is only 1 / 31 / 3 arc-min (option).
This means that the actual backlash at a certain load is a lot Low in an APEX gear box than in virtually any other planetary gear box on the market.
Gearboxes provide torque multiplication, speed reduction, 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 requirements while providing relatively long operating life with zero-maintenance requirements: the planetary gearbox.
A planetary gearbox includes multiple planetary gears that revolve around a central sunlight gear while engaging with an internal gear and rotating by themselves axes. The continuous engagement of the planetary gears means the strain is definitely shared by multiple teeth, allowing planetary designs 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 common characteristics of servo applications. Most servo applications also require very specific positioning, and planetary gearboxes are designed and manufactured to have low backlash, with as little as 1-2 arcmin in some cases.
Planetary gearboxes may use spur or helical gears. While spur gears can possess higher torque ratings 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 put into the drivetrain, the rotational rate delivered from the motor to the driven planetary gearbox for servo motor component is reduced by the quantity of the gear ratio, which can allow the program to make better use of the servo motor’s speed-torque characteristics. Planetary gearboxes have the ability to accept high input speeds and offer speed reduced amount of up to 10:1 for standard styles, with high-speed designs providing equipment ratios (and, therefore, acceleration reduction) of 100:1 or more.
Planetary gearboxes could 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 any case – grease or oil lubrication – planetary gearboxes tend to be lubricated for the life span of the gearbox by the product manufacturer, which eliminates maintenance for the finish user.
The most important benefit of using a gearbox in a servo system is arguably its effect on the inertia of the load. The load inertia, which is reflected to the motor, is reduced by the sq . of the apparatus ratio. So a good relatively small gear reduction can have a significant effect on the inertia ratio.
A right angle planetary gearbox with output shaft combines the benefits of a compact right angle gearbox and the ones of a typical planetary gearbox.
With its versatile mounting 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 dependable component for the proper angle transmitting of torque and acceleration.
