The gear boxes are constructed with stainless, except from the insight flanges which are made of anodized aluminum. Protection class IP65 is regular – IP67 offered as option – which is acheived utilizing a patented insight 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 1 / 31 / 3 arc-min (option).
This means that the actual backlash at a particular load is MUCH LOWER in 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, particularly, require gearboxes that may supply not only high torque with low added inertia, but also high precision and stiffness. One type of gearbox meets all these requirements while providing relatively lengthy operating life with zero-maintenance requirements: the planetary gearbox.
A planetary gearbox contains multiple planetary gears that revolve around a central sun equipment while engaging with an interior gear and rotating by themselves axes. The continuous engagement of the planetary gears means the strain is shared by multiple teeth, allowing planetary styles 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 precise positioning, and planetary gearboxes were created and manufactured to have low backlash, with as little as 1-2 arcmin in some instances.
Planetary gearboxes can use spur or helical gears. While spur gears can have got higher torque rankings 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 velocity delivered from the engine to the driven element is reduced by the quantity of the equipment ratio, which can allow the program to make better utilization of the servo motor’s speed-torque characteristics. Planetary gearboxes are able to accept very high input speeds and offer speed reduced amount of up to 10:1 for standard designs, with high-speed designs providing gear ratios (and, therefore, swiftness 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 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 finish user.
The most important advantage of utilizing a gearbox in a servo system is arguably its influence on the inertia of the strain. The load inertia, which can be planetary gearbox for servo motor reflected to the motor, is reduced by the sq . of the apparatus ratio. So a good relatively small gear decrease can have a substantial influence on the inertia ratio.
