In order to test the rubber ring 3 of the rubber-coated sprocket, the embodiment discloses a rubber-coated sprocket adhesive property testing device applied to a lathe, which comprises a first fixing sleeve 4, a second fixing sleeve 5 and a pull rod, wherein the first fixing sleeve 4 comprises a first clamping section 42 and a small sprocket sleeve 41.
When the first fixing sleeve 4 and the second fixing sleeve 5 are respectively fixed on two sides of the large chain wheel 2, the small chain wheel sleeve 41 is sleeved on the small chain wheel 1, the end part of the small chain wheel sleeve is connected with one side of the large chain wheel 2, the end part of the second fixing sleeve 5 is connected with the other side of the large chain wheel 2, the first fixing sleeve 4 and the second fixing sleeve 5 are connected through a pull rod penetrating through the rubber-coated chain wheel, and obviously, the pull rod penetrates through the centers of the first fixing sleeve 4 and the second fixing sleeve 5. The inner round hole of the small sprocket sleeve 41 is preferably in clearance fit with the outer diameter of the small sprocket 1, and the clearance between the inner round hole and the small sprocket sleeve is not more than 2 mm, so that the coaxiality between the first fixed sleeve 4 and the sprocket is ensured.
The pull rod of the present embodiment includes a first pull rod 61 and a second pull rod 62, where a threaded hole is provided at an end of the first pull rod 61, and the second pull rod 62 is connected to the threaded hole through a corresponding external thread. The second fixing sleeve 5 is connected with one side of the large chain wheel 2 through a flange 51 and is used for lifting the contact area between the second fixing sleeve 5 and the large chain wheel 2.
The parameters of the tip of the turning tool 7 are important to be tested in this embodiment, and are shown in fig. 5: the main deflection angle (angle between the D-plane and the XZ-plane in fig. 5) of the test turning tool 7 should be 90 °, the sub deflection angle (angle between the B-plane and the XZ-plane in fig. 5 and centered on the Z-axis) should be 0 °, and the edge rake angle (angle between the E-plane and the YZ-plane in fig. 5) should be 0 °.
