The RCF 2 Rolling Contact Fatigue Machine is a cut-down version of the TE 92HS Microprocessor Controlled Rotary Tribometer, the key change being the removal of the friction torque measuring arrangement and the clutch assembly used for low speed sliding four ball tests. The RCF 2 machine is used only in the high speed configuration with rolling contact test adapters.
Various well established test adapters are available, including the standard rolling four ball test adapter, typically used for generating surface propagated micro-pitting failures, a cone on angular contact bearing adapter and a thrust ball bearing on disc adapter, which produces rolling with contact spin. All these rely on the high speed test spindle bearings to react the applied axial load. In addition to these, modifications have been made to the spindle and housing to allow back-to-back testing of angular contact bearings. This arrangement results in no axial load on the test spindle, allowing loads up to 40 kN to be applied to the test samples.
The RCF 2 has PC based sequence programmable control and data acquisition. This is provided by an integrated Serial Link Interface Module and COMPEND 2000 software running on a host PC, operating under Windows. Data is stored to hard disc in standard spread sheet compatible file formats (.csv or .tsv).
Tests are defined by a sequence of steps, each step containing set-point, data recording rates and alarm level information. Set-points may be adjusted by step change or ramp. The test sequence is followed unless interrupted by the operator or an alarm. Set-points may also be adjusted manually using on screen toggles.
The operating envelope of the machine is based on the L10 and L30 lives of the spindle bearings. The standard load actuator assembly provides a loading range of 200 to 10,000 N. The permissible loads and speeds for tests where the machine spindle reacts the axial load, are as follows:
10 kN | |
---|---|
5 kN | 3,000 rpm |
3 kN | 10,000 rpm |
The high load actuator assembly is used in conjunction with the back-to-back bearing assembly and allows loads of up to 40 kN to be applied to the test bearings and a maximum rotational speed of 10,000 rpm to be achieved.
