Embodiment Construction
[0024] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0025] The specific embodiment of the high-speed light-load bearing testing machine provided by the present invention, such as figure 2 As shown, the bearing testing machine in this embodiment includes a testing machine main shaft 15 and a testing main shaft 11 for wearing test bearings. The main shaft of the testing machine here is the main shaft of an intermediate frequency asynchronous motor, which can also be called an electric main shaft. Here The main shaft of the testing machine and the main shaft of the test machine are arranged coaxially relative to each other. The main shaft 15 of the testing machine has a right connecting shaft section 14, and the testing main shaft 11 has a left connecting shaft section 12. The corresponding arrangement of the two connecting shaft sections is coaxial, and the two connecting shaft sections A connecting tape 1...

The invention particularly relates to a high-speed light-load bearing testing machine and a connecting method of a testing machine spindle and a testing spindle of the high-speed light-load bearing testing machine. The high-speed light-load bearing testing machine comprises the testing machine spindle and the testing spindle, wherein the testing machine spindle and the testing spindle are arranged oppositely and coaxially, and the testing spindle is used for being sleeved with a tested bearing. The high-speed light-load bearing testing machine is characterized in that the testing machine spindle and the testing spindle are each provided with a connecting shaft section, and the connecting shaft sections are arranged correspondingly; the two connecting shaft sections are winded with linkage tape; transmission linkage of the two connecting shaft sections is achieved through the linkage tape winded on the two connecting shaft sections or a middle connecting sleeve which is installed on the two connecting shaft sections in a sleeving mode; and the middle connecting sleeve is in transmission linkage with the two connecting shaft sections through the linkage tape, and then transmission linkage of the two connecting shaft sections is achieved. Noise caused by flange connection is effectively avoided while a high-speed light-load test is achieved, in addition, the connection cost is low relatively, and the assembly mode is simple.
Description
technical field [0001] The invention belongs to the technical field of bearing testing, and in particular relates to a high-speed light-load bearing testing machine and a method for connecting the main shaft of the testing machine and the main shaft of the testing machine. Background technique [0002] The high-speed performance test of high-speed and precision bearings before installation is becoming more and more important, especially for bearings whose high-speed performance parameter dmN value (dm=(inner diameter + outer diameter) / 2, N is the bearing speed) exceeds 2 million. High-speed performance test is the basis for product development and improvement, the prerequisite for product promotion and marketing, and the basis for gaining customer trust. [0003] At present, when high-speed and precision bearings are tested on a test machine bench, the test bearings are first installed on the test main shaft and in the test seat, and then the test main shaft 1 is connected w...
