The equipment boxes are made of stainless steel, except from the insight flanges which are constructed of anodized aluminum. Security class IP65 is standard – IP67 available as choice – which is acheived utilizing a patented input sealing and a patented result sealing system.
Standard backlash is merely 5 respectively 7 arc-minute (1 resp. 2 levels), reduced backlash is merely 3 / 5 arc-min (option) and lastly micro backlash is one third1 / 3 arc-min (option).
This implies that the actual backlash at a certain load is MUCH LOWER in an APEX gear box than in virtually any other planetary gearbox for servo motor 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 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 zero-maintenance requirements: the planetary gearbox.
A planetary gearbox includes multiple planetary gears that revolve around a central sun equipment while engaging with an internal gear and rotating on their own axes. The constant engagement of the planetary gears means the strain is usually 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 normal characteristics of servo applications. Most servo applications additionally require very precise positioning, and planetary gearboxes were created and manufactured to possess low backlash, with less than 1-2 arcmin in some instances.
Planetary gearboxes can use spur or helical gears. While spur gears can have got higher torque ratings than helical gears, helical styles have smoother operation, less sound, and higher stiffness, making helical planetary gearboxes the favored gearbox for servo applications.
Whenever a gearbox is put into the drivetrain, the rotational quickness delivered from the electric motor to the driven component is reduced by the amount of the equipment ratio, that may allow the program to make better use of the servo motor’s speed-torque characteristics. Planetary gearboxes can accept very high input speeds and offer speed reduced amount of up to 10:1 for standard styles, with high-speed styles providing gear ratios (and, therefore, velocity 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 frequently lubricated with grease. In any case – grease or essential oil lubrication – planetary gearboxes are often lubricated for the life 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 influence on the inertia of the strain. The strain inertia, which is definitely reflected to the electric motor, is decreased by the square of the gear ratio. So a good relatively small gear reduction can have a substantial influence on the inertia ratio.
