When the adjusting component is in the first position, the measuring head is perpendicular to the generatrix of the top cone of the bevel gear; when the adjusting component is in the second position, the measuring head is not perpendicular to the generatrix of the top cone of the bevel gear; when the body is in the third position, the measuring head is in contact with the generatrix of the top cone of the bevel gear; and when the body is in the fourth position, the measuring head is separated from the generatrix of the top cone of the bevel gear. The parameter L measured by the measuring component is obtained when the adjusting component is in the first position and the body is in the third position, and the cone distance R is calculated as R = L × sinδ. a The δ a The angle of the top cone of the bevel gear.

[0006] In some embodiments, when the bevel gear has a journal, the mounting member has a groove in which the journal is engaged; wherein the groove is V-shaped.

[0007] In some implementations, the groove has a chamfer.

[0008] In some embodiments, the mounting element has a magnetic attraction portion that attaches to the bevel gear.

This enables real-time quantitative detection of the cone distance. Since the connecting component is connected to the mounting component, the measuring component includes a body and a measuring head connected to the body. The body is slidably connected to the adjusting component and can switch between a third and a fourth position. When the adjusting component is in the first position, the measuring head is perpendicular to the generatrix of the top cone of the bevel gear; when the adjusting component is in the second position, the measuring head is not perpendicular to the generatrix of the top cone of the bevel gear; when the body is in the third position, the measuring head is in contact with the generatrix of the top cone of the bevel gear; when the body is in the fourth position, the measuring head is separated from the generatrix of the top cone of the bevel gear. When the adjusting component is in the first position and the body is in the third position, the parameter L measured by the measuring component is obtained, and the cone distance R = L × sinδ. a δ a The cone angle is the apex cone angle of the bevel gear. Therefore, the cone distance can be calculated, which allows for quick acquisition of the bevel gear's cone distance, improving efficiency, eliminating the need for specialized equipment, and reducing costs.

[0024] Combination Figure 1 The bevel gear cone distance measuring device according to this application embodiment includes: a mounting member 10, a connecting member 20, an adjusting member 30, and a measuring member 40. The mounting member 10 is detachably connected to the bevel gear 50. The connecting member 20 is connected to the mounting member 10. The adjusting member 30 is rotatably connected to the end of the connecting member 20 away from the connecting member 20, and can be switched between a first position and a second position. The measuring member 40 includes a body 41 and a measuring head 42 connected to the body 41. The body 41 is slidably connected to the adjusting member 30 and can be switched between a third position and a fourth position. When the adjusting member 30 is in the first position, the measuring head 42 is perpendicular to the generatrix of the top cone of the bevel gear 50. When the adjusting member 30 is in the second position, the measuring head 42 is not perpendicular to the generatrix of the top cone of the bevel gear 50. When the body 41 is in the third position, the measuring head 42 is in contact with the generatrix of the top cone of the bevel gear 50. When the body 41 is in the fourth position, the measuring head 42 is separated from the generatrix of the top cone of the bevel gear 50. When the adjusting member 30 is in the second position, the measuring head 42 separates from the generatrix of the top cone of the bevel gear 50. Specifically, when the adjusting member 30 is in the first position and the body 41 is in the third position, the parameter L measured by the measuring member 40 is obtained, and the cone distance R = L × sinδ. a δ a This refers to the angle of the top cone of the bevel gear 50. For example, the measuring element 40 can be a dial indicator or a micrometer.

[0025] Since the mounting component 10 is detachably connected to the bevel gear 50, when it is necessary to measure the cone distance of the bevel gear 50, the mounting component 10 is installed on the bevel gear 50 without disassembling the bevel gear 50, avoiding clamping errors caused by disassembly and realizing real-time quantitative detection of the cone distance. Since the connecting component 20 is connected to the mounting component 10, the adjusting component 30 is rotatably connected to the end of the connecting component 20 away from the connecting component 20 and can switch between a first position and a second position. The measuring component 40 includes a body 41 and a measuring element connected to the body 41. Measuring head 42 and body 41 are slidably connected to adjusting member 30 and can switch between a third position and a fourth position. When adjusting member 30 is in the first position, measuring head 42 is perpendicular to the generatrix of the top cone of bevel gear 50. When adjusting member 30 is in the second position, measuring head 42 is not perpendicular to the generatrix of the top cone of bevel gear 50. When body 41 is in the third position, measuring head 42 is in contact with the generatrix of the top cone of bevel gear 50. When body 41 is in the fourth position, measuring head 42 is separated from the generatrix of the top cone of bevel gear 50. Specifically, when adjusting member 30 is in the first position and body 41 is in the third position, the parameter L measured by measuring member 40 is obtained, and the cone distance R = L × sinδ. a δ a The cone angle of the bevel gear 50 is given by the angle of the top cone. Therefore, the cone distance can be calculated, which allows for quick acquisition of the cone distance of the bevel gear 50, improving efficiency, eliminating the need for specialized equipment, and reducing costs.

[0026] In some embodiments, the angle of the measuring head 42 is adjusted by rotating the adjusting member 30 on the connecting member 20, so that the measuring head 42 is perpendicular to the top cone generatrix. The body 41 can slide on the adjusting member 30 so that the measuring head 42 can contact the top cone generatrix, and the body 41 can display the parameter L, thereby realizing the measurement of multi-specification bevel gears.

[0027] Combination Figure 1 and Figure 2 In some embodiments, when the bevel gear 50 has a journal 51, the mounting member 10 has a groove 11, and the journal 51 is engaged in the groove 11. The groove is V-shaped, and the journal 51 is engaged with the journal 51 through the V-shaped groove to achieve installation. For example, the mounting member 10 can be made of Cr12MoV, hardened to HRC58-62, with a perpendicularity tolerance ≤0.005mm.

[0028] Combination Figure 2 In some embodiments, the groove 11 has a chamfer, which can prevent the transition arc of the journal 51 from getting stuck, avoid the lack of perpendicularity control, ensure the accuracy of the positioning reference, and guarantee the reliability of the measurement. For example, the chamfer is 3×45°.

[0029] In some embodiments, when the bevel gear 50 does not have a journal, the mounting member 10 has a magnetic attraction portion that attracts the bevel gear 50 to achieve mounting. Exemplarily, the magnetic attraction portion can be made of high energy product neodymium iron boron.

[0030] Combination Figure 1 In some embodiments, a gasket 60 is provided between the mounting member 10 and the connector 20 to ensure the stability of the connection between the mounting member 10 and the connector 20.

[0031] In some embodiments, to facilitate connection between the connector 20 and the adjusting member 30 and the mounting member 10, the connector 20 includes a first connecting portion 21, a second connecting portion 22, and a third connecting portion 23. The first connecting portion 21 is connected to the mounting member 10. The second connecting portion 22 is connected at an angle to the end of the first connecting portion 21 away from the mounting member 10. The third connecting portion 23 is connected at an angle to the end of the second connecting portion 22 away from the first connecting portion 21. The adjusting member 30 is rotatably connected to the end of the third connecting portion 23 away from the second connecting portion 22. Exemplarily, the first connecting portion 21 may be parallel to the third connecting portion 23.

[0032] In some embodiments, the included angle between the first connecting portion 21 and the second connecting portion 22 can be set to 45° to 135°. In this embodiment, the included angle between the first connecting portion 21 and the second connecting portion 22 is 90°, that is, the first connecting portion 21 and the second connecting portion 22 are set perpendicularly, and this should not be construed as a limitation of this application.

[0033] In some embodiments, the included angle between the third connecting portion 23 and the second connecting portion 22 can be set to 45° to 135°. In this embodiment, the included angle between the third connecting portion 23 and the second connecting portion 22 is 90°, that is, the third connecting portion 23 and the second connecting portion 22 are set perpendicularly, and this should not be construed as a limitation of this application.

[0034] Combination Figure 1 In some embodiments, to facilitate the connection between the adjusting member 30 and the connecting member 20, the connecting member 20 further includes a connector 24. The connector 24 is connected to the end of the third connecting portion 23 away from the second connecting portion 22. The adjusting member 30 is rotatably connected to the connector 24.

[0035] Combination Figure 1 In some embodiments, to enable the adjusting member 30 to switch between a first position and a second position, the adjusting member 30 has a first through hole, the connector 24 has a second through hole, and the cone distance measuring device of the bevel gear 50 further includes a locking member 70 and a limiting member. The locking member 70 passes through the first through hole and the second through hole and is connected to the limiting member. For example, the locking member 70 can be a bolt, and the limiting member can be a nut.

[0036] When the adjusting member 30 is to be switched from the second position to the first position, the limiting member on the locking member 70 is released, so that the adjusting member 30 can rotate on the connector 24 through the locking member 70. When the adjusting member 30 reaches the first position, the limiting member on the locking member 70 is locked, so that the position of the adjusting member 30 is determined.

[0037] Combination Figure 1 In some embodiments, the adjusting member 30 includes a gauge clamp. By loosening the gauge clamp, the body 41 can slide so that the measuring head 42 can reach a third position, allowing the measuring head 42 to contact the top cone generatrix for measurement. By locking the gauge clamp, the body 41 can be clamped to ensure that the position of the body 41 is determined.

[0038] In some embodiments, the measuring element 40 further includes a data transmission module connected to the measuring head 42, which transmits the parameters measured by the measuring head 42 to the controller. The controller has a calculation module that calculates parameters based on R=LXsinδ. a The calculation is performed, and the calculated cone distance is displayed on the screen.
