Description

Technical Field

[0002] At present, the transmission methods between shafts mainly include gear transmission, belt transmission and chain transmission. Due to the high precision of gear transmission, it is widely used in the mechanical field. In gear transmission, helical meshing gear sets (integrated herringbone gears and symmetrical helical gears) are often used under high-speed and heavy-load conditions because they can eliminate axial forces and carry large loads.

[0003] In order to improve the uniformity of force between the shafts, the two shafts are connected by two sets of helical meshing gear sets. In order to reduce the axial force of the shaft, the helical meshing gear sets on the same shaft have opposite rotation directions. When the two helical meshing gear sets in the same group are assembled, due to the certain inclination angle of the helical meshing gear sets, the two helical meshing gear sets will cause angular displacement of the shaft when they are meshed. When the angular displacement of the shaft increases to a certain extent, it is easy for another set of helical meshing gear sets to get stuck, making the installation of the transmission structure between the two shafts difficult. In engineering, the method of symmetrical alternating installation on both sides is generally adopted, and the installation process is time-consuming and laborious; or the gearbox is designed as a split structure, and the installation process will be simple but has strict requirements on the processing accuracy of the gearbox.

The first rotating shaft 2 is inserted into the two housing shaft holes 11 and is rotationally connected to the housing 1 through two sets of displacement adjustment components 5.

[0029] The two sets of helical meshing gear sets 4 are respectively a first rotating gear set 41 and a second rotating gear set 42. The first rotating gear set 41 includes a gear 411 and a gear 412, and the second rotating gear set 42 includes a gear 421 and a gear 422.

The a gear 411 and the c gear 421 are installed at both ends of the first rotating shaft 2, and the b gear 412 and the d gear 422 are installed at both ends of the second rotating shaft 3. The a gear 411 and the c gear 421 are congruent helical gears with opposite helical angles, and the b gear 412 and the d gear 422 are congruent helical gears with opposite helical angles, wherein the diameter of the b (d) gear 412 (422) is greater than the diameter of the a (c) gear 411 (421). The first rotating gear set second rotating gear set second rotating gear set first rotating gear set first rotating gear set second rotating gear set first rotating gear set first rotating gear set second rotating gear set The first rotating gear set 41 and the second rotating gear set 42 are symmetrically installed with respect to the housing 1. The first rotating gear set and the second rotating gear set displacement adjustment component 5 adjusts the distance between the first rotating shaft 2 and the second rotating shaft 3 so that the a gear 411 and the b gear 412, the c gear 421 and the d gear 422 of the first rotating gear set and the second rotating gear set are in a disengaged or engaged state.

[0030] When installing the first rotating shaft 2 and the second rotating shaft 3, first install the first rotating shaft 2 on the housing 1 through the displacement adjustment component 5, then adjust the displacement adjustment component 5 so that the first rotating shaft 2 is away from the second rotating shaft 3, then install the first rotating gear group a gear 411 and c gear 421 on the first rotating shaft 2, then install the second rotating shaft 3 on the housing 1, then install the second rotating gear group b gear 412 and d gear 422 on the second rotating shaft 3, then adjust the displacement adjustment component 5 so that the first rotating gear group and the second rotating gear group a gear 411 and b gear 412, c gear 421 and d gear 422 are meshed, and then the displacement adjustment component 5 is fixedly installed on the housing 1, and the a gear 411 and b gear 412, c gear 421 and d gear 422 of the two sets of helical meshing gear sets 4, the first rotating gear group and the second rotating gear group are meshed at the same time, effectively avoiding the phenomenon of jamming between the helical gears, thereby improving the convenience of installing the transmission structure between the first rotating shaft 2 and the second rotating shaft 3.

[0031] Reference Figure 3 , Figure 4 The displacement adjustment assembly 5 in this embodiment includes an adjustment member 51 and a mounting member 52. The mounting member 52 includes a mounting sleeve 521. The mounting sleeve 521 is inserted into the housing shaft hole 11 and fixedly connected to the housing 1. In this embodiment, the mounting sleeve 521 is fixedly connected to the housing 1 by welding. A mounting shaft hole 522 coaxially arranged with the housing shaft hole 11 is formed in the middle of the mounting sleeve 521. The adjustment member 51 includes an adjustment sleeve 511. The outer peripheral surface of the adjustment sleeve 511 forms an adjustment cylinder 512. When the adjustment sleeve 511 is inserted into the mounting shaft hole 522, the adjustment cylinder 512 is in contact with the hole wall of the mounting shaft hole 522, so that the mounting sleeve 521 supports the adjustment sleeve 511, thereby improving the installation strength of the first rotating shaft 2.

[0032] Reference Figure 3 , Figure 4The inner hole of the adjusting sleeve 511 forms a transmission shaft mounting hole 513, the first rotating shaft 2 is inserted into the transmission shaft mounting hole 513, and the outer ring of the bearing 14 on the first rotating shaft 2 is loosely matched with the transmission shaft mounting hole 513, the center O1 of the transmission shaft mounting hole 513 is eccentrically arranged with the center O2 of the mounting shaft hole 522, and the distance between O1 and O2 is L, and the value of L is set as required. An end cover 514 is provided on the end of the adjusting sleeve 511, the end cover 514 is in the shape of a circular plate, and the end cover 514 and the adjusting sleeve 511 are integrally formed, and a through hole for the first rotating shaft 2 to pass through is opened on the end cover 514, and the aperture of the through hole is smaller than the aperture of the transmission shaft mounting hole 513, so that the end cover 514 can prevent the bearing 14 on the first rotating shaft 2 from sliding out of the transmission shaft mounting hole 513. The end cover 514 is coaxially arranged with the mounting shaft hole 522 , and the outer diameter of the end cover 514 is larger than the aperture of the mounting shaft hole 522 to ensure that the end cover 514 fits closely with the end wall of the mounting sleeve 521 .

[0033] When adjusting the distance between the first rotating shaft 2 and the second rotating shaft 3, since the transmission shaft mounting hole 513 and the shell shaft hole 11 are eccentrically arranged, the first rotating shaft 2 can be moved closer to or away from the second rotating shaft 3 by rotating the adjusting sleeve 511, thereby improving the convenience of adjusting the distance between the first rotating shaft 2 and the second rotating shaft 3.

[0034] Reference Figure 4 , a plurality of mounting screw holes 523 are provided on the end wall of the mounting sleeve 521. In this embodiment, the number of mounting screw holes 523 is eight, and the eight mounting screw holes 523 are arranged at 45° intervals along the circumference of the mounting sleeve 521. The end cover 514 is provided with end cover mounting holes 524 corresponding to the mounting screw holes 523 one by one. The end cover 514 is provided with a plurality of bolts 525, which pass through the end cover mounting holes 524 and are screwed into the corresponding mounting screw holes 523 to complete the installation of the end cover 514 and the housing 1. After the adjustment sleeve 511 is rotated N*45° (N is an integer), the bolts 525 can still fix the end cover 514 on the housing 1.

[0035] Reference Figure 4 The end cover 514 is provided with a positioning hole 61. In this embodiment, there are two positioning holes 61, which are arranged 180° apart along the circumference of the end cover 514. The end of the mounting sleeve 521 is provided with a limiting matching hole 62 corresponding to the positioning hole 61, and the connecting line of the centers of the two limiting matching holes 62 passes through the center of the end cover 514. The positioning pin 63 passes through the positioning hole 61 and is inserted into the limiting matching hole 62 to complete the circumferential limitation of the end cover 514. At this time, the distance between the first rotating shaft 2 and the second rotating shaft 3 is in the maximum state or the minimum state.

[0036] Reference Figure 5In this embodiment, when the center O1 of the transmission shaft mounting hole 513, the center O2 of the mounting shaft hole 522, and the center O3 of the second rotating shaft 3 are collinear, and O1 is located between O2 and O3, the distance between the first rotating shaft 2 and the second rotating shaft 3 is the shortest. At this time, the a gear 411 and the b gear 412, the c gear 421 and the d gear 422 are in meshing state, and the end cover mounting hole 524 is aligned with the mounting screw hole 523, and the positioning hole 61 is aligned with the limit matching hole 62.

At this time, the first rotating gear group and the second rotating gear group of gear a 411 and gear b 412, gear c 421 and gear d 422 are in a disengaged state, and the end cover mounting hole 524 is aligned with the mounting screw hole 523, and the positioning hole 61 is aligned with the limiting matching hole 62.

[0038] The implementation principle of Example 1 is as follows: when the first rotating shaft 2 and the second rotating shaft 3 are installed, after the first rotating shaft 2 and the first rotating gear set 41, and the second rotating shaft 3 and the second rotating gear set 42 are installed, the adjusting sleeve 511 is driven to rotate 180°, O1, O2, and O3 are in the same line, and O1 is located between O2 and O3. At this time, the distance between the first rotating shaft 2 and the second rotating shaft 3 is the shortest, and the a gear 411 and the b gear 412, and the c gear 421 and the d gear 422 are in the second rotating gear set of the first rotating gear set. The movable gear group is in meshing state, and then the end cover 514 is fixed to the installation sleeve 521 by bolts 525 to complete the installation of the transmission structure of the first rotating shaft 2 and the second rotating shaft 3. During the installation process, the a gear 411 and the b gear 412, the c gear 421 and the d gear 422 on both sides of the first rotating gear group and the second rotating gear group are meshed at the same time, which effectively avoids the first rotating gear group 41 and the second rotating gear group 42 from getting stuck, thereby improving the convenience of installing the transmission structure between the first rotating shaft 2 and the second rotating shaft 3.

[0039] Example 2 Reference Figure 7 The difference between this embodiment and embodiment 1 is that the a gear 411 and b gear 412 in the first rotating gear set 41 and the c gear 421 and d gear 422 in the second rotating gear set 42 in this embodiment are herringbone gears, and each herringbone gear can be formed by splicing two congruent helical gears with opposite helical angles, or by processing a single gear.
