Shafts for extending door drives

Inconspicuous at first glance elements, such as shafts for extending door drives , have an important purpose in controlling the electric circuit. They allow the assembly of control and executing components, regardless of the type of housing. The shafts are the link and extension of the door drives. They cooperate with circuit breakers, disconnectors and switches mounted in switchboards, electrical cabinets and control panels. The maximum length of one element of the extension allows the drive shafts to be used in electrical cabinets up to 600 mm deep.

On the market, depending on the manufacturer and the assembly system, there are shaft fasteners directly to the drive on the cabinet door or permanently fastened to the switch or disconnector. The systems available on the market allow the selection of individual elements adequate to the requirements of a given control module. All shafts are suitable for installations up to 1600 A.

Shafts for door drives - versatile applications

The shafts for extending door drives are most often made of metal. They are resistant to damage and ensure failure-free operation of the systems connected to them. Extension shafts do not interfere with operation and do not adversely affect the comfort of operation, regardless of the mounted drive. They also meet the quality and safety standards for accessories for servicing electrical components. They work with all types of drives, both rotary drives, levers and remote drives.

Rollers - necessary in the construction of the installation

Extension shafts are also called idlers and can come in different variants. Most often they appear in square sections, but hexagonal sections are also offered. Extension profile height mainly comes in 8mm, 10mm, 12mm, and 14mm sizes. The available lengths range from 100 mm to 600 mm. The drive axle extension can be adjusted to the specific size if necessary by shortening it. The shaft can also be mounted in most common types of joints rotating every 90 degrees. Such a system is offered by Eaton .

, among others

All drive shafts cooperate with both side and front disconnectors and switches. Positioning in the drive is done using small, protruding side pins. In some types of shafts it is possible to connect them with couplers. The connection of the two parts is secured by locking screws that prevent unwanted disconnection.

To facilitate the search process and shorten the time needed to select the appropriate devices, ready-made assembly kits are also available. An example would be the set: 3 gear. P1 switch disconnector with metal 400mm extension and Eaton padlock rotary actuator.
