The Thompson Constant Velocity Joint (TCVJ) is a means of transmitting drive across an angled join between driving and driven shafts with a true one-to-one ratio between the shafts. The traditional problems associated with driving power around a corner of heat, vibration, loss of rotation and oscillating shaft speeds that have been inherent in universal joint technologies have all been addressed and overcome by the TCVJ.
Running at near to ambient temperatures, with no inherent vibration in its design, the TCVJ and its associated sliding shaft actually deals with vibrational inputs from gearboxes, reduction units and motors in a way that protects and prolongs the life of the system. Having no weight bearing sliding elements, the TCVJ has been born out of a re-understanding of the vectoring forces in play in rotating shafts and directional changes. The TCVJ does not need phased or parallel connecting flanges as has been required for traditional universal joints.
• Allows the design of the driveline around the requirements of the application, accommodating up to 10 degrees of misalignment
• Requires NO laser alignment but more importantly – absorbs vibration protecting both motor and driven shaft.
• Reduces power cost.
• Reduces operating costs – Long running life
• Maintenance Free – Sealed for life
• Reduces downtime breakdowns, operating temperatures and power losses
• Relieves the misalignment problems and premature wear caused by thermal expansion, vibration and soft footing
• Minimises the damaging forces that impact on bearings, seals and bodies through side load, overhung and axial load
• Articulates up to 10 degrees angular misalignment, in combination with parallel misalignment.
• Extends and compresses to accommodate movement between connected devices.
Quick release flanges allow for easy installation and replacement of the TCAE.
1. Simply fix the flanges on the pump and motor shafts.
2. Compress the TCAE to fit in between.
3. Then expand and attach the TCAE
1.If necessary, move the drive/driven device to the correct “end-to end” shaft distance, in order to fit the TCAE in between.
2. Slide the taper lock bush inside the quick release flange. Do not completely tighten the screws from the taper lock bush against the flange. Repeat the operation for the other flange and bush.
3. Slide both quick release flanges onto both drive & driven device shafts with appropriate shaft keys. For best results, locate flange ends flush with the end of the shaft. Alternatively, at least 50% of the flange should be placed on the shaft. Tighten the taper lock bush screws adequately.
4. If necessary, use a sling to insert the TCAE in a horizontal position. Compressing and expanding the TCAE as necessary, slide it between both flanges. Secure the TCAE to both flanges by tightening the bolts in a diametrically opposite sequence.
