Description

Technical Field

[0001] The utility model relates to the technical field of housing diameter gauges, in particular to a differential housing inner spherical diameter gauge. Background Art

[0002] The differential housing transmits power to the wheels on both sides at different speeds through the internal gear system. When the vehicle turns or drives on uneven roads, there will be a speed difference between the wheels on both sides. The gear system inside the differential housing will automatically adjust the speed of the wheels on both sides to ensure smooth driving of the vehicle.

[0003] The existing differential housing inner spherical diameter gauge can refer to the Chinese utility model patent with authorization announcement number CN217585601U, which discloses a differential housing inner spherical diameter gauge, "including a left detection support seat and a right detection support seat, the left detection support seat is fixedly provided with a guide column, the right detection support seat is slidably provided on the guide column, an elastic member is provided between the left detection support seat and the right detection support seat, one end of the left detection support seat and the right detection support seat are both provided with a detection spherical block, the two detection spherical blocks are located on the same axis, a micrometer is provided on the outer side of the right detection support seat, the micrometer is fixedly provided on the guide column through the micrometer support seat, and the measuring rod of the micrometer points to the right detection support seat."

[0004] When the above device is in use, the existing device uses the detection part to directly extend into the differential housing for detection, and the external micrometer directly reads the size error, which is easy to use, has high detection efficiency, and low cost of the inspection tool. However, when the existing inspection tool is used for detection in the differential housing, the arc shape and diameter size of the inner spherical surface are not taken into account, resulting in a poor inspection effect of the inspection tool. In addition, the existing inspection tool cannot detect the diameter size of the connecting shaft port, and it is impossible to avoid effectively understanding the connecting shaft port on the differential housing. Therefore, a differential housing inner spherical diameter inspection tool that solves the above problems is needed. Utility Model Content
