SPM is an abbreviation for the Shock Pulse Method, which is a patented technique for using signals from rotating rolling bearings as the basis for efficient condition monitoring of machines. From the innovation of the method in 1969 it has now been further developed and broadened and is now a worldwide accepted philosophy for condition

SPM HD can be used to monitor applications in the 0.1 - 20,000 RPM range. Throughout their lifetime, bearings generate shocks int he interface between the loaded rolling element and the raceway. These shocks 'ring' the SPM transducer which outputs electric pulses proportional to the shock magnitude. Unlike vibration transducers, the shock pulse

SPM is a well-established technique. Initially, SPM was launched to enable the technician to cost-effectively track bearing condition. The tool proved effective as a method to assess general lubrication requirements as well. Shock Pulse Basic Principle of Operation. SPM stands for shock pulse monitoring.

Shock Pulse Method filters out this phase of the collision, as the magnitude of the vibration is structure and material dependent. The shock pulse method was invented in the late 1960s. The amplitude of these impacts is determined by three different parameters. A comparison of some condition monitoring

The shock pulse meter counts the rate of occurrence (incoming shock pulses per second) and varies the measuring threshold until two amplitude levels are determined: The shock carpet level (approx. 200 incoming shocks per second). This level is displayed as dBc (decibel carpet value). The maximum level (greatest incoming shock under 2 seconds).

The shock pulse method (SPM) has been widely used as a quantitative method for bearing condition monitoring. However, the shock value indicating the bearing condition may be mistakenly estimated by direct demodulation in the SPM. To overcome this deficiency, a new approach based on improved redundant lifting scheme (IRLS) is proposed.

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.

Vibration enveloping is commonplace for many of you. The shock pulse method was invented in the late 1960s. In rolling element bearings, there is a phenomenon where electric waves, or elastic waves, or shock pulses, or impact signals, are generated. The amplitude of these impacts is determined by three different parameters.
