摘要： A rheology unit comprising a drive shaft unit where the drive shaft minimises or eliminates mechanical backlash delivered to a Couette cell is disclosed. Commercially available Rheo-NMR systems have significant limitations on the type and resolution of analysis that can be undertaken. In known Rheo-NMR practices, a drive shaft is mounted within the NMR magnet and a shear cell, such as a Couette, is fitted to the drive shaft within the machine. To attach the Couette to the drive shaft, a pin is located through aligned apertures in the drive shaft and Couette. However, to allow the Couette to be attached to the drive shaft relatively easily, the apertures are significantly larger than the diameter of the pin. This means that as the drive shaft rotates, there is a time delay before the pin engages with the Couette to cause the Couette to rotate. This time delay is referred to as mechanical backlash or mechanical slop, which means that it is not possible to continue analysing the sample accurately when the direction of rotation of the drive shaft changes, thus limiting the range of possible experiments to those relating to a constant shear rate in a single direction. The connection between the shafts is by thread to eliminate the mechanical backlash.

摘要： A rheological measurement device adapted to be used in a bore of an NMR magnet, the measurement device comprising a drive shaft, a drive shaft housing (230) in which the drive shaft is located, and a torque sensor (250) directly or indirectly attached to the drive shaft, wherein the torque sensor is positioned substantially in line with the drive shaft. A shear cell (400) is connected top the torque sensor. The device may further comprise a drive shaft extension system. A system for measuring sheer in a substance may be formed by the addition of a drive system comprising a motor (340) coupled to the drive shaft and adapted to rotate the drive shaft. The drive system includes a control system (320) with a positioning sensor (330) for identifying the orientation of the drive shaft in relation to the drive shaft housing. It is disclosed that commercially available Rheo-NMR devices do not include a torque sensor, which prevents these devices from measuring global rheological parameters, such as shear stress, during NMR experiments. Without simultaneous measures of both NMR and global rheological parameters it is difficult to compare NMR measurements of molecular dynamics with a material’s torque response to imposed strain.
