Description

Technical Field

[0001] This invention belongs to the field of gear transmission and relates to a bevel gear meshing auxiliary positioner and positioning method. Background Technology

[0002] Gear transmission is an important mechanical transmission method, and bevel gear transmission can change the direction of force transmission. For example, bevel gears are used in gearboxes to make full use of limited space. Compared to ordinary gears, bevel gears have a more complex structure and force transmission method. Gear meshing transmission requires higher precision; if the gear meshing is not optimal, it will increase wear between the two gears and reduce their service life. Therefore, ensuring the relative position and perpendicularity of the bevel gears during meshing is a crucial step in bevel gear transmission. Previously, there were no specialized fixtures for positioning bevel gears or special tools for determining whether the meshing degree between bevel gears was appropriate. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a bevel gear meshing auxiliary positioner and positioning method, which can position the relative position and perpendicular relationship of two bevel gears so that the meshing of the two bevel gears reaches the optimal state.

[0004] To achieve the above objectives, the present invention employs the following technical solution:

[0005] A bevel gear meshing auxiliary positioner includes a positioning body and a detachable push rod;

[0006] The positioning body includes two perpendicular straight rods. The free end of the first straight rod is provided with a first connector. The center of the second straight rod is provided with a through hole parallel to its length direction. The front end of the through hole is located at the intersection of the second straight rod and the first straight rod, and the bottom end of the through hole is located at the free end of the second straight rod. The front end of the detachable push rod extends into the front end of the through hole and extends out from the bottom end of the through hole as a second connector. At this time, the detachable push rod and the second straight rod are detachably and fixedly connected.

[0007] Preferably, the length of the two straight rods of the positioning body is equal to the distance from the end face to the intersection of the axes after the two bevel gears mesh.

[0008] Preferably, the detachable push rod has two opposing protrusions on its circumferential surface near the second connector, and the inner wall of the through hole has two opposing straight grooves along the axis of the through hole. The through hole has an annular groove at the bottom of the straight groove. When the protrusions are located in the annular groove, the front end of the detachable push rod extends from the bottom of the through hole as the second connector.

[0009] Preferably, the front end of the through hole is provided with an internal thread, and the front end of the through hole is threadedly connected to an end cap. The bottom end of the end cap is open, the inside is hollow, and the top is sealed. The bottom end of the end cap is provided with an external thread. There are two opposing protrusions on the circumferential surface of the removable push rod near the second connector. There are two opposing straight grooves along the axial direction of the through hole on the inner wall of the through hole. When the protrusions are located at the bottom of the straight grooves, the front end of the removable push rod extends from the bottom end of the through hole as the second connector, and the top end of the end cap rests against the rear end of the removable push rod.

[0010] Preferably, there are two opposing spring pins on the circumferential surface of the removable push rod near the second connector. The spring pins are spherical in shape. An annular groove is provided on the inner wall of the through hole near the bottom of the through hole. When the spring pin is located in the annular groove, the front end of the removable push rod extends from the bottom of the through hole as the second connector.

[0011] Preferably, the diameters of the first and second connectors are 6-8 mm.

[0012] Preferably, the lengths of the first and second connectors are 8-15mm.

[0013] Preferably, when the two bevel gears are the same size, the two straight rods are the same length, and the first joint and the second joint are the same length.

[0014] Preferably, when the two bevel gears are of different sizes, the joint length connected to the larger bevel gear is longer, and the straight rod length connected to the smaller bevel gear is longer.

[0015] A positioning method based on the bevel gear meshing auxiliary positioner, wherein the first connector of the positioning body extends into one of the bevel gears, and a detachable push rod is combined by passing through the second straight rod of the positioning body. The front end of the detachable push rod extends from the bottom end of the through hole as the second connector. At this time, the detachable push rod and the second straight rod are detachably and fixedly connected. The other bevel gear is installed on the second connector, and the two bevel gears are adjusted until they are fully meshed. The two bevel gears are then fastened to the mounting shaft.

[0016] After the bevel gear is installed, remove the detachable push rod from the second straight rod, remove the first connector from the bevel gear, and then remove the positioning body.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention ensures verticality through an L-shaped positioning body. Two connectors are inserted into two bevel gears. The relative length relationship between the two connectors in two directions ensures that the relative positions of the two bevel gears can be positioned, so that the meshing of the two bevel gears reaches the optimal state. Furthermore, the detachable push rod is detachably and fixedly connected to the second straight rod, allowing the detachable push rod to be directly removed after the bevel gear meshing installation is completed, and the positioner can be removed without damaging the meshing state of the bevel gears.

[0029] Example 1

[0030] like Figure 1-5 As shown, the bevel gear meshing auxiliary positioner of the present invention includes a positioning body 1 and a detachable push rod 2.

[0031] The positioning body 1 includes two perpendicular straight rods, which are integrated into one piece, making the positioning body 1 an L-shaped component.

[0032] The length of the two straight rods of the positioning body 1 is equal to the distance from the end face to the intersection of the axes after the two bevel gears mesh, ensuring reliable meshing of the two bevel gears.

[0033] The first straight rod has a first connector 4 at its free end, and the second straight rod has a through hole at its center that is parallel to its length direction. The front end of the through hole is located at the intersection of the second straight rod and the first straight rod, and the bottom end of the through hole is located at the free end of the second straight rod. The front end of the detachable push rod 2 extends into the through hole from the front end and extends out from the bottom end of the through hole as a second connector 5. At this time, the detachable push rod 2 and the second straight rod are detachably and fixedly connected.

[0034] In this embodiment, the removable push rod 2 and the second straight rod are detachably and fixedly connected in the following way: there are two opposing protrusions 3 on the circumferential surface of the removable push rod 2 near the second connector 5, and two opposing straight grooves along the axial direction of the through hole on the inner wall of the through hole. The through hole is provided with an annular groove at the bottom of the straight groove. When the protrusions 3 are located in the annular groove, the front end of the removable push rod 2 extends out from the bottom of the through hole as the second connector 5.

[0035] The diameters of the first connector 4 and the second connector 5 are 6-8 mm, and the lengths of the first connector 4 and the second connector 5 are 8-15 mm, thus enabling them to accommodate bevel gears of different sizes. When the two bevel gears are the same size, the lengths of the two straight rods are the same, and the lengths of the first connector 4 and the second connector 5 are the same. When the two bevel gears are different sizes, the connector connected to the larger bevel gear is longer, and the straight rod connected to the smaller bevel gear is longer, thus making it suitable for bevel gear meshing of different sizes.

[0036] like Figure 6 As shown, the bevel gear meshing and positioning process in this embodiment is as follows: the first connector 4 of the positioning body 1 extends into one of the bevel gears, the removable push rod 2 passes through the second straight rod of the positioning body 1 for assembly, the protruding structure 3 is moved to the end of the straight groove inside the second straight rod, the removable push rod 2 is rotated at a certain angle in the annular groove to ensure that the removable push rod 2 cannot be pulled out from the second straight rod, the other bevel gear is installed on the second connector 5, the two bevel gears are adjusted until they are fully meshed, and the two bevel gears are fastened to the mounting shaft.

[0037] After the bevel gear is installed, rotate the removable push rod 2 to the straight groove, pull the removable push rod 2 downward, and then remove the positioning body 1 horizontally.

[0038] Example 2

[0039] Compared with other embodiments, this embodiment differs in the way the detachable push rod 2 and the second straight rod are detachably fixed. Specifically, the front end of the through hole is provided with an internal thread, and an end cap is threadedly connected to the front end of the through hole. The bottom end of the end cap is open, hollow inside, and sealed at the top. The bottom end of the end cap is provided with an external thread. There are two opposing protrusions 3 on the circumferential surface of the detachable push rod 2 near the second connector 5. There are two opposing straight grooves along the axial direction of the through hole on the inner wall of the through hole. When the protrusions 3 are located at the bottom of the straight grooves, the front end of the detachable push rod 2 extends from the bottom end of the through hole as the second connector 5, and the top end of the end cap abuts against the rear end of the detachable push rod 2.

[0040] The bevel gear meshing and positioning process in this embodiment is as follows: the first connector 4 of the positioning body 1 extends into one of the bevel gears, the removable push rod 2 passes through the second straight rod of the positioning body 1 for assembly, the protruding structure 3 is moved to the end of the straight groove inside the second straight rod, the end cap is threaded to the front end of the through hole until the top of the end cap abuts against the rear end of the removable push rod 2, thereby fixing the removable push rod 2 and the second straight rod, the other bevel gear is installed on the second connector 5, the two bevel gears are adjusted until they are fully meshed, and the two bevel gears are fastened to the mounting shaft.

[0041] After the bevel gear is installed, rotate to remove the end cover, pull out the removable push rod 2 along the straight groove, and remove the positioning body 1 laterally.

[0042] Example 3

[0043] Compared with other embodiments, this embodiment differs in the way the detachable push rod 2 and the second straight rod are detachably fixed. Specifically, there are two opposing spring pins on the circumferential surface of the detachable push rod 2 near the second connector 5. The spring pins are spherical structures. An annular groove is provided on the inner wall of the through hole near the bottom end of the through hole. When the spring pin is located in the annular groove, the front end of the detachable push rod 2 extends out from the bottom end of the through hole as the second connector 5.

[0044] The bevel gear meshing and positioning process in this embodiment is as follows: the first connector 4 of the positioning body 1 extends into one of the bevel gears, the removable push rod 2 is passed through the second straight rod of the positioning body 1 and combined, the front end of the removable push rod 2 is inserted from the front end of the through hole, and the spherical spring pin can retract with a certain force, the spring pin is moved to the annular groove, the spring pin pops out, ensuring that the removable push rod 2 cannot be easily pulled out from the second straight rod, the other bevel gear is installed on the second connector 5, the two bevel gears are adjusted until they are fully meshed, and the two bevel gears are fastened to the mounting shaft.

[0045] After the bevel gear is installed, pull out the detachable push rod 2 forcefully and remove the positioning body 1 laterally.
