Automatic Bearing Vibration Measuring Instrument
Bearing
Vibration reflect the overall quality of bearing, it will directly influence
the performance of bearing. Therefore strict inspection on bearings must be
executed in order to secure the quality of bearings. Existed bearing vibration inspecting
instrument only caters for the inspection for single bearing. In order to
satisfy the developing requirement of the inspection of full range of bearing,
our company has developed the highly efficient automatic bearing vibration
inspection instrument based on our pre-existed multi-functional bearing vibration
measuring instrument.
The automatic
bearing vibration measuring instrument majorly consists of mechanical system,
testing system, pneumatic control system and electric control system. The instrument
is highly efficient and facilitates the function of automatic vibration
measuring for both side of deep groove ball bearing and automatic
categorization of bearings in terms of vibration value. The automatic bearing
vibration measuring instrument is suitable for the application of workshop
floor.
Characteristics
l The mechanical system major consists of frame, double-work
station shaft system, automatic infeed and outfeed mechanism and automatic
loading equipment.
l The control and measuring of the machine are carried out by
industrial computer, PLC, sensor and signal conversion circuit.
l Applies anti-interference mechanism: the machine utilizes low-noise
component and adopt specialized electric matching and manufacturing techniques,
in order to secure the reliability of the operation of measuring system.
l Multi-parameter measuring, parameters used for analyzing the vibration
of bearing consists of vibration (acceleration type)’s mean square root and
peak value, peak factor as well kurtosis. And the instrument also facilitate
the function of the multi-parameter analysis of the vibration’s time-frequency
domain based on the stored measuring data.
l Incorporate viral instrument technology, the displayed data
is direct, precise and good in terms of repetitiveness; the operating interface
is easy to operate.
l The machine is two phase controlled with industrial PC and
PLC, the machine has great anti-interference performance.
Technical Parameter
l Applicable product: deep groove ball bearing
l Measuring range: ID F10-F60mm
l Spindle speed: 180r/min+-36r/min
l Measuring efficiency: 8-15s/piece
l Categorizing of bearing: quality parts, acceptable parts and
defect parts
l Radial and axial runout of spindle: ≦5μm
l Physical parameter to be measured: accelerated velocity
l Measuring range (accelerated velocity): 0-80dB
l Response range of frequency: 50-10000HZ A/D conversion: 12
bit
l Measuring and analysis function: effective value; peak value;
peak factor; peak frequency; kurtosis coefficient; power spectrum; cepstrum
analysis and envelope spectrum etc.

XM200 surface profile measuring instrument Performance
ZYS surface profiler is used to do surface profile measurements, including surface geometry and macro geometry for many kinds of mechanical parts,such as groove radius,convexity,roughness,etc.
Features
• X direction used high-precision guide rail for line to move benchmarks, the move distance of guide rail is measured by grating technology.
• Z direction column also used high-precision slide rail and encoders for measurement, the ball screw system is driven by the motor.
• Roughness and profile measurements. With workbench it can measure three-dimensional surface profile, the system can be used standalone, flexible and convenient.
• Measuring software is WINDOWS platform, using the latest domestic standard definition, complete mathematical model.
• A variety of adjustable workbenches, such as rotary workbench, V-type platforms etc. Users can freely choose according to need.
• More measuring parameters such as: linearity, curvature deviation, two grooves bearing various parameters, parallel deviation, height etc. It can also measure surface profile of the mechanical, roughness in strict accordance with domestic standards.
• High Measuring precision, inductance sensor resolution up to 0.01µm , X direction grating resolution is 0.5 µm, Z direction with encoder, it can measure large scale high-precision displacement.
• More control position, it can not only measure traditional small displacement in Z direction and displacement in X direction also the large displacement in Z direction. With control table in Y direction, it can measure three-dimensional surface morphology of parts.
• Use of computer controlling, it can manually or do measurement, it can automatically eliminate installation errors, automatically change range, directly display the shape and parameters, it can print output and has standard database for storing data.
