Leonova™ Infinity – Shock pulse measurement, dBm/dBc Normalized condition scale Input: Rpm plus shaft diameter (or ISO bearing number) For over 30 years, the original Shock Pulse Method (SPM) has been very successfully used to obtain a fast, easy and reliable diagnosis of the operating condition of rolling element bearings. Shock pulse amplitude is due to three basic factors: • Rolling velocity (bearing size and rpm) • The mechanical state of the bearing surfaces (roughness, stress, damage, loose metal particle). Throughout their lifetime, bearings generate shocks in the interface between...

Leonova™ Infinity – Shock pulse measurement, LR/HR Evaluation boxes determined by bearing geometry and speed Calibration The LR/HR method was developed from the original Shock Pulse Method for condition diagnosis of rolling element bearings. It allows a precision analysis of oil film condition in the rolling interface and contains calculation models for finding the optimal lubricant. Poor lubrication is the root cause of most bearing failures. Signal and measurement Transducer and measuring procedure are the same as for the dBm/dBc method (TD-213). The shock pulse meter counts the rate of...

Leonova™ Infinity – SPM Spectrum Damage severity Pattern recognition: Bearing with rotating inner race and a damaged outer race. BPFO = ball pass frequency outer race and its multiples dominate the shock pulse spectrum. The purpose of 'SPM Spectrum' is to verify the source of high shock pulse readings. Shocks generated by damaged bearings will typically have an occurrence pattern matching the ball pass frequency over the rotating race. Shocks from e. g. damaged gears have different patterns, while random shocks from disturbance sources have none. Signal and measurement The resonance...

Leonova™ Infinity – Vibration ISO 2372 Broad band vibration measurement is the most widely used and cost-efficient method for the diagnosis of general machine condition. There are two ISO recommendations concerning this type of machine condition monitoring, the much used ISO 2372 and the more recent ISO 10816, which is a ongoing replacement of the older standard. In Leonova, vibration measurement according to ISO 2372 is a platform function, always included for unlimited use. The features are: • Machine condition is diagnosed on the basis of broad band measurements returning an RMS value of...

Leonova™ Infinity – Vibration ISO 10816 with spectrum Broad band vibration measurement is the most widely used and cost-efficient method for the diagnosis of general machine condition. There are two ISO recommendations concerning machine condition monitoring by this type of measurement, the much used ISO 2372 and the more recent ISO 10816, which is an ongoing replacement of the older standard. With Leonova, ISO 2372 measurement is a platform function, always included for unlimited use (see TD-225). ISO 10816 is an option with ordering numbers LEO133 (unlimited use) and LEO233 (limited use)....

Leonova™ Infinity – FFT spectrum with symptoms FFT Spectrum with Symptoms is a vibration analysis function offered with Leonova, for either limited or unlimited use. It is a reduced form of EVAM (Evaluated Vibration Analysis Method), lacking the function true zoom, the statistical evaluation by means of criteria and possibility to display and save time signal (option). Spectrum analysis with 'symptoms' This function generates three sets of machine condition data: Most symptoms are automatically configured by using the rpm as a variable, for some an input is needed, e. g. the number of vanes...

Leonova™ Infinity – EVAM evaluated vibration analysis EVAM stands for Evaluated Vibration Analysis Method. With Leonova, the EVAM method is offered as an analysing function with either limited or unlimited use. The EVAM method generates three sets of machine condition data: • Condition parameters, which are measured and calculated values describing various aspects of machine vibration. • Vibration spectra where significant line patterns are found, highlighted and evaluated with the help of preset fault symptoms. • Machine specific condition codes (green, yellow, red) and condition values,...
