The gear boxes are constructed with stainless, except from the insight flanges which are made of anodized aluminum. Security class IP65 is regular – IP67 offered as option – 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 phases), reduced backlash is just 3 / 5 planetary gearbox for servo motor arc-min (choice) and lastly micro backlash is 1 / 31 / 3 arc-min (option).
This means that the actual backlash at a particular load is a lot Reduced an APEX gear box than in any other planetary gear box out there.
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 criteria while providing relatively long operating life with low maintenance requirements: the planetary gearbox.
A planetary gearbox consists of multiple planetary gears that revolve around a central sunlight equipment 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 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 additionally require very exact positioning, and planetary gearboxes are designed and manufactured to possess low backlash, with as little as 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, much less noise, and higher stiffness, producing helical planetary gearboxes the favored gearbox for servo applications.
When a gearbox is put into the drivetrain, the rotational acceleration delivered from the motor to the driven element is reduced by the amount of the equipment ratio, that may allow the system to make better usage of the servo motor’s speed-torque characteristics. Planetary gearboxes are able to accept very high input speeds and provide speed reduction of up to 10:1 for standard styles, with high-speed designs providing equipment ratios (and, therefore, rate reduction) of 100:1 or higher.
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 of the gearbox by the product manufacturer, which eliminates maintenance for the finish user.
The most important advantage of using a gearbox in a servo system is arguably its influence on the inertia of the strain. The strain inertia, which can be reflected to the motor, is reduced by the square of the gear ratio. So even a relatively small gear decrease can have a significant effect on the inertia ratio.
