[0029] The core of the present invention is to provide a three-dimensional garage and its transmission pair gear clearance adjustment mechanism to realize the adjustment of the mating clearance of the transmission pair gears and ensure accurate transmission.

[0030] To enable those skilled in the art to better understand the technical solutions provided by the present invention, the following will further elaborate on the present invention in conjunction with the drawings and specific embodiments.

[0031] Please refer to Figures 1 - 5 , to solve the above-mentioned prior art problems, the present invention provides a transmission pair gear clearance adjustment mechanism, including a first adjustment mechanism and a second adjustment mechanism.

[0032] Among them, the first adjustment mechanism is used to adjust the gear clearance of the helical teeth of the worm 6 relative to the worm gear 3; the second adjustment mechanism is used to adjust the gear clearance of the motor gear 5 of the reduction motor 2 relative to the worm wheel gear 4 of the worm 6.

[0033] First, adjust the helical teeth of the worm 6 relative to the worm wheel 3 to an appropriate gear clearance value to ensure precise meshing between the worm 6 and the worm wheel 3. Then, adjust the motor gear 5 of the reduction motor 2 relative to the worm gear 4 of the worm 6 to an appropriate gear clearance value to ensure precise meshing between the motor gear 5 and the worm gear 4. By using the above-mentioned gear clearance adjustment mechanism for the transmission pair, the gear clearance can be adjusted to ensure precise transmission.

[0034] The gear clearance value can be detected by an instrument. When it is within the standard range, it is precise transmission, and the relative positions of all components can be fixed by a clamping device.

[0035] In the specific implementation manner, the first adjustment mechanism includes a cover plate 7, a sliding seat 8, and a first clamping device.

[0036] An installation hole for rotatably connecting the worm 6 is provided on the sliding seat 8. The cover plate 7 is arranged on the outer shell 11 of the column of the stereoscopic garage. The sliding seat 8 is slidably arranged on the cover plate 7, and the first clamping device is used to limit the relative movement between the sliding seat 8 and the cover plate 7.

[0037] Specifically, since the position of the outer shell 11 of the garage column is fixed, a second bolt hole 1101 is provided on the outer shell 11. The cover plate 7 is provided with a first bolt hole 702 for fixing to the outer shell 11. Bolts fix the cover plate 7 and the outer shell 11 through the first bolt hole 702 and the second bolt hole 1101. The sliding seat 8 is slidably arranged on the cover plate 7, and the worm 6 is arranged in the installation hole of the sliding seat 8 through a bearing. To adjust the gear clearance between the worm 6 and the worm wheel 3, that is, by adjusting the position of the sliding seat 8 on the cover plate 7, approaching or moving away from the worm wheel 3, and adjusting to an appropriate clearance value, then fix the sliding seat 8 on the cover plate 7.

[0038] Furthermore, a receiving cavity 1102 is also provided on the outer shell 11. The sliding seat 8 is placed in the receiving cavity and has a certain degree of freedom of movement in the adjustment direction.

[0039] Furthermore, an oblong hole 701 extending in the adjustment direction is provided on the cover plate 7. A sliding seat connection hole is provided on the sliding seat 8. The first clamping device is a bolt, and the bolt passes through the oblong hole 701 and the sliding seat connection hole to fasten the sliding seat 8 and the cover plate 7. After the worm is installed on the cover plate 7 through the sliding seat 8, it can be adjusted along the extending direction of the oblong hole. After adjusting to an appropriate meshing clearance, fasten the sliding seat 8 and the cover plate 7 with bolts.

[0040] Of course, the sliding seat 8 can also be slidably arranged on the cover plate 7 through a guide rail mechanism. One of the sliding seat 8 and the cover plate 7 is provided with a slider, and the other is provided with a chute that slidably cooperates with the slider. After adjusting to an appropriate meshing clearance, the relative movement between the sliding seat 8 and the cover plate 7 is restricted by the first clamping device.

[0041] In the specific implementation manner, the second adjustment mechanism includes a motor mounting seat 9, a base 10, and a second clamping device.

[0042] The motor mounting base 9 is used to connect the reduction motor 2 and is slidably arranged on the base 10. The second clamping device is used to limit the relative movement between the motor mounting base 9 and the base 10. In particular, the base 10 can also be provided with pulleys to facilitate pushing.

[0043] Specifically, one of the motor mounting base 9 and the base 10 is provided with a strip-shaped groove extending along the adjustment direction, and the other is provided with a connection hole. The second clamping device is a bolt, and the bolt passes through the strip-shaped groove and the connection hole to fasten the motor mounting base 9 and the base 10. When adjusted to the appropriate meshing clearance, the relative movement between the motor mounting base 9 and the base 10 is restricted by the second clamping device, so as to ensure the meshing of the worm gear and the motor gear.

[0044] Of course, the kidney-shaped hole and the strip-shaped groove can be of the same or different shapes and structures, but the length extension directions of both are in the direction close to or away from the worm wheel.

[0045] Similarly, the motor mounting base 9 can also be slidably arranged on the base 10 through a guide rail mechanism. One of the motor mounting base 9 and the base 10 is provided with a slider, and the other is provided with a chute that slidably cooperates with the slider. When adjusted to the appropriate meshing clearance, the relative movement between the motor mounting base 9 and the base 10 is restricted by the first clamping device.

Therefore, the three-dimensional garage with this transmission pair gear clearance adjustment mechanism also has all the above technical effects, which will not be elaborated one by one here.

[0047] Specifically, the three-dimensional garage includes a column, and the column mainly includes a housing 11, a stopper 1, a reduction motor 2, a worm 6, a worm wheel 3, and a transmission pair gear clearance adjustment mechanism.
