Technical Field

[0002] In engineering machinery, equipment such as tensioners use a reduction gear structure with a central drive and symmetrical reverse dual output. This type of structure usually uses a motor connected to a planetary reducer, and the planetary reducer is connected to a parallel shaft reducer to achieve the purpose of synchronous reverse output. However, this type of structure is usually difficult to meet the input centering condition, and the motor and planetary reducer have a long external suspension. When the suspension is deformed by gravity, the phase angle of the reducer output wheel changes, which is prone to accidents. At the same time, the reducer is a planetary reducer, which is difficult to maintain and has certain requirements for the manufacturer. Therefore, there are still shortcomings and deficiencies in the existing technology. Utility Model Content

DETAILED DESCRIPTION
[0015] The present invention will be further described below with reference to the accompanying drawings. Figure 2 The direction in shall prevail.
[0016] like Figure 1-3As shown, the utility model provides a centered single-input reverse dual-output reducer, including a reducer housing 1, an input component 2, a transmission component 3 and an output component 4 are provided in the reducer housing 1, the input component 2 is transmission-connected to the output component 4 through the transmission component 3, the input component 2 includes a high-speed shaft 21 located on the center line of the reducer housing 1, the high-speed shaft 21 is rotationally connected to the reducer housing 1 through a bearing 6, one end of the high-speed shaft 21 passes through the outside of the reducer housing 1 and is fixedly connected to a coupling 5, and a high-speed gear 22 is keyed to the high-speed shaft 21; the output component 4 includes two symmetrically arranged output hollow shafts 41, the output hollow shaft 41 is rotationally connected to the reducer housing 1 through a bearing 6, and a low-speed gear 42 is keyed to the output hollow shaft 41.
[0017] The transmission assembly 3 includes a primary intermediate shaft 31 and two secondary intermediate shafts 33. The two secondary intermediate shafts 33 are located between the two output hollow shafts 41. The secondary intermediate shaft 33 is rotatably connected to the reducer housing 1 through bearings 6. A secondary transmission gear set 34 is provided on the secondary intermediate shaft 33. The two secondary transmission gear sets 34 are transmission-connected to each other. The secondary transmission gear set 34 is transmission-connected to the low-speed gear 42. The secondary transmission gear set 34 on the left is transmission-connected to the low-speed gear 42 on the left, and the secondary transmission gear set 34 on the right is transmission-connected to the low-speed gear 42 on the right. The primary intermediate shaft 31 is located between the left secondary intermediate shaft 33 and the high-speed shaft 21. The primary intermediate shaft 31 is rotatably connected to the reducer housing 1 through bearings 6. A primary transmission gear set 32 is provided on the primary intermediate shaft 31. The primary transmission gear set 32 is transmission-connected to the high-speed gear 22, and the primary transmission gear set 32 is transmission-connected to a nearby secondary transmission gear set 34.
[0018] Specifically, when in use, the output shaft of the motor is connected to the high-speed shaft 21 through the coupling 5, and the motor drives the high-speed shaft 21 to rotate at high speed. Figure 3 As shown, the high-speed shaft 21 drives the secondary transmission gear set 34 on the left to rotate through the high-speed gear 22 and the primary transmission gear set 32, the secondary transmission gear set 34 on the left drives the low-speed gear 42 on the left to rotate, and the low-speed gear 42 on the left drives the output hollow shaft 41 on the left to rotate. At the same time, the secondary transmission gear set 34 on the left drives the secondary transmission gear set 34 on the right, the secondary transmission gear set 34 on the right drives the low-speed gear 42 on the right to rotate, and the low-speed gear 42 on the right drives the output hollow shaft 41 on the right to rotate, so that the motor drives the two output hollow shafts 41 to rotate synchronously. Since the two secondary transmission gear sets 34 are meshed, the two secondary intermediate shafts 33 rotate in opposite directions, so that the two output hollow shafts 41 rotate in opposite directions, thereby achieving the effect of reverse synchronous dual output.
[0019] The utility model integrates the planetary reducer and the parallel shaft reducer into one, making the structure safer and more stable, and convenient for later maintenance. It can also reduce the length and weight of the external suspension, thereby reducing the deformation of the suspension. At the same time, compared with the planetary reducer, the utility model has lower requirements for processing and assembly accuracy, thereby reducing the production difficulty and thus saving costs to a large extent.
[0020] In some embodiments, the primary transmission gear set 32 includes a primary input gear 321 and a primary output gear 322. The diameter of the primary input gear 321 is larger than the diameter of the primary output gear 322.

The secondary transmission gear set 34 includes a secondary input gear 341 and a secondary output gear 342. The diameter of the secondary input gear 341 is larger than the diameter of the secondary output gear 342. The secondary input gear 341 and the secondary output gear 342 are both key-connected to the secondary intermediate shaft 33. A secondary input gear 341 close to the primary output gear 322 is meshed with the primary output gear 322. The two secondary input gears 341 are meshed together. The secondary output gear 342 is meshed with the low-speed gear 42. The left secondary output gear 342 is meshed with the left low-speed gear 42, and the right secondary output gear 342 is meshed with the right low-speed gear 42. Specifically, during use, since the diameter of the first-stage input gear 321 is larger than the diameter of the first-stage output gear 322, and the diameter of the second-stage input gear 341 is larger than the diameter of the second-stage output gear 342, when the high-speed shaft 21 drives the two output hollow shafts 41 to rotate through the transmission assembly 3, the rotational speed of the two output hollow shafts 41 can be reduced.
[0021] In some embodiments, both ends of the output hollow shaft 41 extend out of the reducer housing 1 , so that the output hollow shaft 41 can be connected to equipment such as a tension machine.
[0022] The above embodiments can be combined with each other.
