The selection of a drive
When designing an industrial application, selecting a suitable drive is of paramount importance. Not only the end customer (= user) benefits from a suitable drive combination, but also the machine builder (OEM) can save a lot of time, costs and image damage.
Although there is a lot to select yourself, a number of things are often overlooked. In addition to the correct mounting position, consider the terminal box position, the service factor and also the power consumption of the application. As a result, there may be too much or too little oil in a gearbox, bearings are not lubricated properly or a too large (expensive) gearbox has been selected.
A check on the thermal capacity of a gearbox is also often “a neglected child”.
What is the thermal power of a gearbox?
In addition to the ability of a gearbox to transmit power, there is also something called the “thermal capacity” of a gearbox. Simply put, the ability of the cabinet to dissipate the temperature/heat. The thermal capacity of a cabinet is mainly determined by the design of the gearbox, the total surface area and internal space determine the heat dissipation.
An incorrect selection can therefore lead to major and costly problems, especially with the beautiful summers we have experienced last year. Without additional cooling or with a “tight selection”, a cabinet can overheat and cause significant damage internally.
The operating environment and usage
Should a very short operating time or very low ambient temperature apply, the concept of thermal power can be relatively unimportant. With S1 operation or longer periods at full (peak) power, or if there may be higher ambient temperatures, the concept of thermal power becomes a lot more relevant.
