Flexible shafts


Flexible shafts are the machine elements assigned to the transmission of motions between two axes which do not coincide or whose mutual position while working change.

Flexible shafts are manufactured by winding up of quality steel wire in several layers.

               
                                             
                                     transmission shafts                                                         torsion shafts

Depending on application flexible shafts are divided as follows:
1. flexible shafts for transmission of torque in diameter up to Ø 6mm ;

Technical characteristic flexible shafts

Flexible shafts, as a machine assembly, consists of metal protective covering coated with PVC lining, flexible shaft (core) and two complete joints, one on drive side, another on instrument side.

The complete flexible shafts can be made with different joints on both sides and with different protective coverings.

In order to choose and to order the flexible shaft it is necessary to state the code of flexible shaft and number of pieces.
                                               

All above diameters are our products in casing like bovden
                                                 

• up to Ø 12,0 mm have bin manufacturing bovden with PVC cover
  
                                          

• and over Ø 12,0 mm it bovden is producing by metal flexible construction.
  
                                          

Except flexible shafts in our production program is in closed products for transmission of the power and/or torque

Instruction

 Flexible shafts - type SV- 12M
 Modern construction of this shaft except many advantages, has important characteristic because during use has not elongation of protection armor, which made by steel spring strip, braid by steel, covered by PVC material, drawn in rubber with fittings and protection spring. It can be connected on all types of pervibrators from our production program.
 Transmission of engine torque is by flexible shafts on vibration end of the its head which producing vibrations.
Optimal number of vibrations has directly influence on quality of concrete mass.

 Pervibrations heads in dimensions DN 30, DN 45 and DN 60 can be connected on the same shaft since connection elements are standardized. During operation the head should be step be step by step immersed in concrete mass and held. Then take out it slowly to enable hole closing. Remove of the head is depending on radius of activity. Depth of immerse of head is max. 800 mm, but more then this caused over load of pervibrator. It is need that head of pervibrator in operations. It until appearance on surface circles like concrete as to avoid over heating.

It is known that soot deposits, which are formed on the walls of the flue hose reduce the efficiency of thermal power fuel. To reduce these losses, and deposits must be removed. Earlier this done manually and it was slow, difficult, dirty and unhealthy job.
Cleaning of boiler tubes is done quickly, easily and well to our devices. The advantages of using these devices are undoubtedly large compared to manual cleaning:
- significantly higher quality of cleaning
- excluded the possibility of damage to pipes
- significantly shortening the time required for cleaning. Manual cleaning is performed by 5 workers for 15 hours while our device 2 workers performing the job for only 5 hours
- The savings in fuel consumption. Thanks to the quality of cleaning reduces the losses which can result in fuel savings that can be up to 10%

Possibility of applying
Devices can be used for cleaning all types of boiler tube of inner diameter DN 38 to DN 75 mm and lengths up to 13 m.

Operating principles
The chuck positioned at the end of a flexible shaft which receives rotary motion from the electric motor is set brush or other cleaning tools. By insertion of a flexible shaft with chuck, and a brush for cleaning the tube and the rotation the brushes to remove plaque from the walls of the tube.

Devices for boiler tubes cleaning:

• transformer and electric motor,
  

• flexible shafts with head
  

Electrical motor is galvanized separated from shaft by plastic fitting for connection of engine armor and stator. Flexible shafts core is galvanized separated from rotor by plastic coupling. Transmission from motor to tool is by flexible shaft. It has been using for remove of soot from walls of hase.

Type:

• Devices for boiler tubes cleaning type CK M-1
  

• Devices for boiler tubes cleaning type CK M-2
  

Application:
In process equipment industry rubber, wood, glass one as well as foundries, locksmith workshops and other places here the tool position is changeable in all direction during work and for the other devices access is impossible or there are many difficult.

Flocked flexible shafts covered with spring wire or without it

Application:
In car flexible construction.

• Flocked bovden
  

Application:
For alleviation of notice during of operation.

Devices for testing of welded parts quality in Institutes (Gama Mag and Gama Volt)
               

Device for remote discharge of isotopes used for remote control ejection of isotopes in materials and weld joints without damage.
It consists of glass, gear drives, spiral core with the coating and the corresponding connections.
Unit design allows connection to defectoscopy GAMMAMAT and GAMMAVOLT while for other types defectoscopy must submit manufacturer drawing or sample ports.
It is made in lengths of 5 to 15 m according to customer with the possibility of ejection of isotopes at a distance of 0.30m to 10m.
Aptly chosen plant materials provide the durability of the device in use of 20000 to a throw in time expressed it 1.5 years with proper handling and maintenance as confirmed by the certificate of quality.

Apparatus for grinding and polishing products that “Panaflex” have very simple structure, low weight, ease of operation and maintenance and high elasticity of the flexible shaft. They consist of: drive motor, flexible shaft, chuck and the base (only for devices UBM 10-8S and the UBM 15-8S).

Thanks to the traits possessed by these devices are widely used in industrial process equipment, rubber, wood and glass industry, tool, pattern shop, foundry , hardware shops and other places for grinding and polishing tools, where the position is changed in all directions during the work and where other devices to access difficult or impossible.

Before starting work with the devices necessary do the following:
1. For three-phase drive motors to verify direction of rotation of the engine by comparing it with the arrow marks. In the case of the opposite direction of rotation of two phases to replace the plug. For single phase motor rotation direction is factory set.
2. Connect the flexible shaft to the drive motor and then connect the chuck with the proper tools.
3. After these actions the device is ready for work.

Apparatus for grinding and polishing UBM UBM 12-1 and 15-1 were mono phase with a single speed and UBM UBM 12-2 and 15-2 are phase two the number of revolutions and the UBM 15-2A, which is indirectly reduced. Change of speed is done by turning the switch in position 1 or 2with the proviso that it must ensure that during the transition from larger to smaller engine speed to a complete stop.

UBM devices and 10-8S 15-8S UBM are three phase. Change the number of turning them come in the following way: pick up the fuse lever, turn a bit eccentric until the required speed appears on the housing slot and then turn the cam to the right until it snaps in the fuse groove. With regard to the two eccentric read speed, the upper smaller number is obtained when the switch drive motor is in position 1 and the lower higher speed when the switch is in second position Change the number of revolutions made ​​only when the engine is idle.
