Performance Analysis Test Bench for BR-ZCS Liquid Dynamic Pressure Bearings

(Desktop)


Overview:
1、 Experimental projects that can be completed:
1.1. Observe the formation process of dynamic pressure lubricating oil film in radial sliding bearings;
1.2. Measure and draw the radial pressure distribution curve and axial pressure distribution curve of the dynamic oil film of the radial sliding bearing, and calculate the bearing capacity;
1.3. Understand the measurement method for the friction coefficient of radial sliding bearings and the drawing method for the friction characteristic curve.
2、 Basic structure:
2.1. The experimental platform has a desktop structure and the base is made of structural components;
2.2. The experimental platform adopts sensors that can collect experimental data such as rotational speed, oil film pressure, oil temperature, external load, and friction between experimental bearings. There are 7 radial measurement points and 2 axial measurement points. An oil temperature sensor is required to ensure accurate viscosity testing of lubricating oil.
3、 Main functions:
3.1. Measure the radial oil film pressure distribution and determine its friction characteristic curve;
3.2. The bearing adopts oil immersion lubrication method, which uses the rotation of the shaft to bring lubricating oil into the bearing;
3.3. The external load loading method adopts spiral loading, which can change the load size by rotating the spiral, and adopts photoelectric speed measurement and LED digital display;
3.4. The measurement and control system of the experimental platform is connected to the computer through RS232 serial port. Multimedia software collects, processes and analyzes experimental data, and can display and print the distribution curves of radial and axial oil film pressure; It can also be displayed in a panel window and manually record experimental data; DC motors must be able to manually and continuously change speed.
4、 Technical parameters:
4.1 One experimental bearing: inner diameter d=60mm, effective length L=120mm;
Spindle speed control range: 3-375r/min; Roughness of 1.6 µ m; Material ZQSn6-6-3, the distance between the force measuring point on the force measuring rod and the center of the bearing L=90 mm;
4.2 DC motor: 1 DC servo motor; Power 375W/220V; Speed regulation range 0-1500 r/min, speed regulation power supply (SK400B) 1 output voltage DV 0-220V output current DA 0-4A, manual stepless speed change;
4.3. One friction sensor with a range of 50N;
8 pressure sensors with a range of 0-1.6MPa and an accuracy of 2.5%;
1 external load sensor, range: 0-5000N, accuracy ± 0.2%, loading: 0-5000N;
1 temperature sensor, range: -40 ± 85 ° C
