Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of spline shaft detection, in particular to a spline shaft bearing weight detection machine. Background Art
[0002] A spline shaft is a type of mechanical transmission. Like flat keys, woodruff keys, and wedge keys, spline shafts transmit mechanical torque. They have longitudinal keyways on their outer surface, and rotating parts on the shaft also have corresponding keyways, allowing them to rotate synchronously with the shaft. While rotating, some parts can also slide longitudinally on the shaft, such as the shift gears in a transmission.
[0003] In order to ensure the load-bearing capacity of the spline shaft, the spline shaft will be sampled for laboratory mechanical property testing. This test refers to the specifications and cuts part of the original material for tensile, bending moment, tensile elongation and other tests. To analyze the deformation of the spline shaft and its impact on the load-bearing capacity of the entire spline shaft, it is necessary to perform an axial compression test on the entire spline shaft. Existing testing equipment cannot fix the spline shaft being tested. When applying pressure to the spline shaft, the pressure of the testing equipment will cause the spline shaft being tested to tilt or shift position, resulting in inaccurate pressure test data of the spline shaft, which affects the user's work.
