SYJ-d20-60 10000 rpm Bearing Test Bench Main Components
SYJ-d20-60 bearing life test machine mainly consists of a bed, a
test body, a drive system, a loading system, a lubrication system,
an air cooling system, an electrical control system, and software,
as shown in Figure 1.
Figure 1 (Overall configuration of the railway bearing test bench)
1) Matrix
The Matrix, regarded as the base of the railway bearing test bench, is made
of ductile iron, which can ensure the stability of the test bench
in high-speed rotation and large load operation.
2) Test bench body
The test bench body is the core part of the railway bearing test bench, and its
structure is the key to the railway bearing test bench technology.
The test bench body consists of a loading device, a test shaft system, a test bearing,
a loading mechanism, etc.

Test Bearing Tooling
3) Drive system
The driving motor adopts a servo motor, which adopts speed closed
loop control. The motor transmits speed and torque to the test
spindle. The motor power is 37kW, and the motor characteristic
curve is as follows.
Meet the test characteristics: Motor control speed range 100～±2000
rpm.
Servo motor characteristic curve
4) Loading system
The loading system adopts a hydraulic servo valve closed loop mode.
The hydraulic loading system will be placed outside the test bench
body, which is convenient for maintenance and heat dissipation. The
hydraulic loading system is an important part of the
electro-hydraulic closed loop servo loading system.
5) Lubrication system
The lubrication system is the equipment bearing lubrication system.
To meet the lubrication requirements for the equipment bearings,
the lubrication system should be equipped with supply and return
oil pumps.
6) Control system and electrical parts
The control system consists of Omron programmable controller,
programmable control terminal, frequency conversion drive unit,
various sensors (temperature, speed, pressure, vibration)
acquisition units, motors, etc.
7) Air cooling system
The axial flow fan uses the ultra-low noise axial flow fan produced
by Texas Asia Pacific Group Co., Ltd., YTCZ-6.3F, with an air
volume of 15800 m3/h, a wind speed of 10m/s, and a controlled air
supply speed.
