Problems solved by technology
[0003] In the high-speed test of the existing bearing testing machine, the high-speed electric spindle is generally used to directly drive the test spindle to rotate. This method often cannot carry the test load during the large-load and low-speed test, resulting in some tests that cannot be realized.

The invention provides an automobile water pump shaft connecting bearing test machine, which comprises a durability test component and a torque test component which are arranged on a test bed, whereinthe durability test component is formed by a driving servo motor I, a transmission speed increasing component, a durability test tool component and a mechanical servo loading component; the torque test component is formed by connecting a driving servo motor II, a coupling, a transmission shaft system, a torque sensor, a plum coupling and a torque test tool component in sequence; and a test bearing is arranged in the torque test tool component. The test machine has the beneficial effects that in the durability test, the driving mode of two-stage belt transmission is adopted, so that the transmission output form is changed into constant-torque output, and the driving capacity of the driving motor is improved; a loading system adopts a mechanical servo loading mode, and the loading mode hasthe advantages of being high in loading response speed, high in control precision, simple in structure of the whole device, small in size and the like.
Description
technical field [0001] The invention relates to a bearing testing machine, in particular to an automobile water pump shaft-connected bearing testing machine. Background technique [0002] The automotive water pump shaft bearing testing machine can simulate the actual working conditions of the water pump shaft bearing, and conduct life tests under the conditions of high temperature, high speed and predetermined tension. It can test the waterproof sealing performance or assembly test of the shaft coupling bearing of the water pump. While the testing machine is doing the life test of the shaft coupling bearing of the water pump, the detection test of the starting torque of the shaft coupling bearing of the water pump can be realized on the test device on the other side of the testing machine. [0003] In the high-speed test of the existing bearing testing machine, the high-speed electric spindle is generally used to directly drive the test spindle to rotate. This method often ...
