Rolling bearings acceptance test

In order to achieve reliability, repetition and safety of bearings diagnostics results, it is required to provide the following conditions: pre-washing (for depreservation), finishing washing and drying of bearings, pre-visual-measuring control with magnetization measuring, bearings preservation after the acceptance tests. These conditions are provided by bearings acceptance test area, which in addition to the COMPACS®-RPP system includes:

  • tanks with heating for preliminary and finishing washing, drying and preservation of bearings;
  • malfunctions detection and demagnetization desk, with a demagnetizing device and magnetization measuring device, illuminated magnifier, indicators for micromeasurements (radial clearance, radial runout) with a magnetic holder;
  • packing desk.

Bearings acceptance tests area features:

  • stainless steel tanks;
  • support of operation fluids temperature;
  • completeness and flexibility of kitting.

A partial delivery of the system with a set of necessary technical means is possible on the Customer’s request.

The COMPACS®-RPP system features

The system operation does not require the highly qualified personnel – it is usually carried out by metalworkers of 4-5 categories.

Bearing quality is evaluated according to velocity and vibration acceleration in 4 frequency bands. The expert system for bearings defects diagnostics is based on vibration signal envelope spectrum analysis and automatically indicates particular bearings defects: of inner and outer races, rolling and separator elements, higher radial clearance and others. An original method of rolling bearings vibration control is implemented in the system, and vibration level rates are set for the following types of bearings: radial ball bearings, angular ball bearings, radial roller bearings with short cylindrical rollers, radial spherical double-row roller bearings and conical roller bearings.

Bearings database includes information on each bearing number, its inner and outer diameters, quantity of rolling elements, their diameters and contact angles. The software allows to correct the information according to bearings parameters from the operator’s panel. Bearing frequencies calculation considering rotation frequency is carried out automatically. Moreover, there is a possibility to collect information on tested bearings signals in the special archive.

The COMPACS®-RPP rolling bearings vibration analysis system meets the requirements of GOST 520, GOST 24955, GOST 24346, ISO 2041, ISO 15242, including GOST 53563-2009, GOST 53564-2009, GOST 53565-2009, developed by SPC "Dynamics", patented methods of SPC "Dynamics", using А_S, A_F1, A_F2, A_F3, V_S, V_F1, V_F2, V_F3, and a powerful analytical software complex for measurement of vibroacoustic signals noise components. The system has a certificate of approval for measuring devices types as a set of components, which determine the system metrological characteristics.

Engineering solutions, implemented in the system, are protected by the Russian Federation Patents on various objects of intellectual property and Certificates of official registration for computer programs.

"MONITOR" mode screen

The COMPACS®-RPP-AE system is a modification of the computer monitoring system COMPACS® and is developed for rolling bearings health monitoring and recourse-influencing defect diagnostics, considering results of vibration and acoustic emission parameters measuring.

Bearing health is evaluated in 4 frequency ranges considering the results of digital processing of acoustic emission sensors signals being displayed in the form of colored pictograms and numerical values of vibration and acoustic emission parameters. The system complies with the requirements of GOST 520-2002, GOST 52545.1-2006, ISO 15242-1:2004.

Application of micrometric measuring devices and form factors has allowed to reduce noise rates of the bearing stand, thus enabling to check bearings with vibration categories up to "Sh9".

In comparison with the COMPACS®-RPP system, the COMPACS®-RPP-AE system allows to check the drive noise rates according to velocity and vibration acceleration together with a channel of vibration measuring in octave and one-third-octave frequency bands.

The COMPACS®-RPP-AE system advantages:

  • incipient defects diagnostics on acoustic emission parameters;
  • wider measurement range of RMS vibration parameters (vibration acceleration: 0,03-500 m/s2; velocity: 0,01-50 mm/s);
  • lower level of the drives noises rates;
  • bearings diagnostics can be carried out in all the vibration categories: from Sh to Sh9;
  • wider range of a spindle rotation frequency: 30-3000 rpm;
  • wider range of loadings: 0-2000 N;
  • the system completing with extra sensors of temperature, vibration, acoustic emission and motion;
  • control of temperature and drives units vibration;
  • application of high-precision units and special equipment.

Operation modes of the COMPACS®-RPP and the COMPACS®-RPP-AE systems

In order to present different types of information, there are several working modes (screens):

  • "MONITOR" Mode displays information on the controlled unit health.
  • "ANALYSIS" Mode provides analysis of the signals spectra received from the vibration transducer.
  • "SYSTEM" Mode displays information on the built-in self-control system.
  • "OSCILLOGRAPH" Mode provides analysis of the signal form and the system set-up.
  • "ARCHIVE" Mode provides search, viewing and printing of the electric motor test reports.

Rolling bearings acceptance tests economic benefits

Cost of bearing acceptance tests, according to information from our customers, is 41-47 rubles per month in case of less than 1000 bearings tests, in case of more bearings test - less than 40 rubles. Thus, one can get bearings of a guaranteed high quality at a considerably lower price than high-quality and "Sh" category bearings.

Economic efficiency calculations indicate that the COMPACS®-RPP systems compensation period is less than a year, and a net present value (NPV) is more than 50 million rubles. Besides, general level of the equipment safety increases, and failures quantity significantly reduces.

Engineering solutions, implemented in the system, are protected by the Russian Federation Patents on various objects of intellectual property and Сertificates of official registration for computer programs.

Warranty for supplied equipment - 12 months.
