BARFLEX® Couplings

Barrel Coupling

 

Features:

  • The barrel couplings have covers with special seals which help maintain the tightness of the inner zone. They prevent the penetration of dust and promote the continuity of the lubrication. Two double-lamina elastic rings mounted on the hub, one on each side of the toothing, limit the axial displacement of the barrels.
     
  • The convex shape of the barrels and the internal spaces of the toothing allow the oscillation of the hub relative to the sleeve. This compensates angular misalignment of ± 1°30' and an axial displacement that varies between ± 3 mm and ± 8 mm.
  • Torque is transmitted to the drum's receiving flange by two diametrically opposed flat driving surfaces. These surfaces are located at the periphery of the coupling flange. Torque is also transmitted by a series of bolts, which simultaneously serve as a connection with the drum.
  • The above-described design is appropriate for bearing large radial loads, as these are distributed over large barrel support surfaces. Likewise, this design also minimizes the effect of alternative bending of the torque on the toothing. The latter is robust thanks to its low height and large bottom section. In addition to this, due to the effect of a "crush polishing" of the hardened barrel on the tooth profile, its wear resistance is appreciably improved.


Benefits:

An indicator located on the outer cover permits control of internal wear of the toothing without the need to disassemble any part of the coupling. This indicator moves relative to the marks provided on the hub as a function of wear. The same indicator also serves to control the axial position of the sleeve relative to the hub. Optionally, an electronic wear indicator can be installed for remote control.

To use a barrel coupling instead of a gear coupling will bring a significant decrease in the needed room for the coupling. A barrel coupling is quite narrower than the corresponding gear coupling. The barrel coupling is also partly positioned inside the drum.


Wear Indicator Benefits


  • Real-time wear indicator which shows real progressive wear magnitude against wear limit.
  • Reliable and accurate wear value, even in max. misalignment working conditions.
  • Gives alarm once max. wear limit is reached.
  • Can give a direct signal to crane PLC.
  • Can be placed inside crane control panel.
  • In very dusty working atmosphere positively tested.

TCBR Barrel Coupling

 

Jaure® TCB barrel couplings connect the cable drum with the gearbox output shaft. They are recommended for installation in:

  • crane lifting mechanisms
  • winch conveyors
  • platform hoists 

A statically indeterminate case exists when a gearbox output shaft is rigidly connected to the drum in a lifting mechanism. This type of mounting requires special care in alignment and leveling, which is difficult to achieve in the practice.

Mounting inaccuracies, as well as deformations in structures and wear in moving parts, lead to additional forces for consideration. In particular, the gearbox output shaft, which can be subject to alternative bending loads, can lead to breakage due to fatigue as well as faults in bearings and gear wheels.

The barrel coupling is installed between the gearbox and cable drum. It performs the function of an articulated joint. This makes the connection statically determinate and avoids the occurrence of high bending moments.

 

TCB Coupling Wear Indicator

 

The Jaure coupling electronic wear indicator allows the user to monitor wear remotely. It can be connected to the operator's control system or to an optional display unit. This allows continuous or periodic monitoring of the barrel coupling wear.
