Third, the installation and use of ball bearing abrasion tester

★ This machine is packed in a wooden box. After opening the box, check whether the product certification, packing list, instruction manual and other information are complete, and check whether the contents of the box are complete and consistent according to the product packing.

★ The testing machine qualified for opening the box should be horizontally placed on the workbench. This machine does not need special foundation and anchor bolts, as long as it is level and stable.

★ Plug the water inlet pipe and connect it to the water source, plug in the water outlet pipe, the four-core plug of this machine is connected to the three-phase 380V AC power supply, and it is reliably grounded, then it can be put into use.

★ Put the wear side of the test piece upwards into the test piece holder. There is a moving plate in the test piece holder. It can be adjusted according to the different width of the test piece. The horizontal position of the wear surface can be adjusted by the horizontal adjusting plate. Then, turn the compression screw to clamp the test piece.

★ Place the grinding head on the surface to be worn, turn the lifting handle to lower the frame and the hollow shaft and press it on the grinding head. The balls of the grinding head should be aligned with the lower rollers of the hollow shaft. Be careful that the hollow shaft does not touch the sensor on the grinding head

★ Continue to rotate the lifting handle so that the frame continues to descend until the top of the sensor is aligned with the red engraved line. At the same time, the measuring rod of the dial indicator should be in contact with the top plate, and it should have a 5mm mileage.

★ Turn on the protective cover on the locking handle plate to turn on the water source, and wait for the flowing surface in the water to continue to flow to the abraded surface of the test piece, and start the test.

★ Press the controller's "Move" button, the motor starts to work, when the grinding head rotates about 30 revolutions, it will automatically stop, write down the dial indicator and press the "Reset" button to reset the digital display to zero. Then press the "Start" button again, the machine will start to run. When the grinding head is turned to 1000 revolutions, it will automatically stop recording the dial indicator reading. Press the "Start" button again, the machine will continue to run, and every time When the rotation is 1000, the grinding head ** will stop automatically, and the dial indicator reading will be recorded at the same time, but when the rotation is over 5000, the machine will automatically stop and lock itself. To make the machine run again, you must press the "Reset" button to make the machine run normally. During the running of the machine, if you want to pause the test, you can press the "Stop" button, the stall data is automatically saved, so that Continuity of test data. Completeness and accuracy.

★ The machine frame cannot be rotated.

★ After the test, turn off the water and power and remove the test piece.

Fourth, the structure of ball bearing abrasion tester: Figure:

主机由底座（1），立柱（13），机架（11），电机（15），中空转轴（5），磨头（滚珠轴承）（4），试件夹具（2）等组成。电机（15）与机架（11）连接，通过皮带（12）带动中空转轴（5）工作时，中空转轴在垂直方向无约束，中空转轴（5）和配垂（10）辅件的自重全部压在磨头上。

The main unit consists of a base (1), a column (13), a frame (11), a motor (15), a hollow shaft (5), a grinding head (ball bearing) (4), and a test fixture (2). The motor (15) is connected to the frame (11). When the hollow shaft (5) is driven by the belt (12), the hollow shaft is unconstrained in the vertical direction. Press on the grinding head.

滚珠轴承式耐磨试验机维护和保养：

1、试验结束后，将试验机，主柱及所有工作部分把谁擦干，然后加上防锈油。

2、本机传动部分定期加润滑油，不使用时应每月运转一次。

3、使用过程中，应经常检测磨头滚珠直径，小于15.675MM必须更换。

Fifth, the ball bearing type wear test machine maintenance and maintenance:

1. After the test, wipe the test machine, the main column and all working parts, and then add anti-rust oil.

2. The transmission part of this machine is regularly lubricated. When not in use, it should be run once a month.

3. During use, the diameter of the ball of the grinding head should be checked frequently. If it is less than 15.675MM, it must be replaced.

滚珠轴承式耐磨试验机注意事项：

★该机采用三相380V电源，机外壳必须接地，设备未经可靠接地严禁使用。

★磨头在运转过程中，百分表必须固定，百分表测量头和顶板脱离接触，当运转停止，测量头与顶板接触并读数。

★在试验中，百分表测得磨面面深度≯1.5mm，以防磨头的轴承架磨损毁坏，不准继续试验。

★本机采用传感器接收系统测量磨头转数，一旦发现磨头在运转而控制器的数码显示停止，应立即停机，检查传感器（6）的位置是否处于传感器接收区域。

Six, matters needing attention of ball bearing type abrasion tester

★ This machine adopts three-phase 380V power supply. The casing of the machine must be grounded. The equipment must not be used without reliable grounding.

★ During the running process of the grinding head, the dial indicator must be fixed. The dial gauge measuring head and the top plate are out of contact. When the operation stops, the measuring head is in contact with the top plate and reads.

★ During the test, the depth of the ground surface was measured by a dial indicator mm1.5mm to prevent the bearing frame of the grinding head from being worn and damaged. It is not allowed to continue the test.

★ This machine uses a sensor receiving system to measure the number of rotations of the grinding head. Once it is found that the grinding head is running and the digital display of the controller stops, it should immediately stop and check whether the position of the sensor (6) is in the sensor receiving area.
