Detailed Description
As shown in fig. 1-2, a two-shaft output one-way transmission gear box comprises an input shaft 1, a box body 7 and an output shaft 8,
the axial leads of the two output shafts 8 are positioned on the same straight line, and the axial leads of the input shaft 1 positioned in the middle and the output shafts 8 at the two sides are vertical to each other; one end of the input shaft 1 is arranged on a bearing on the box cover 4, the other end of the input shaft is arranged on a bearing in the box body 7, and the box cover 4 is arranged on the box body 7; one output shaft 8 is arranged on a bearing in the box body 7, and the other output shaft is arranged on a bearing in the bearing block 5; the bearing seat 5 is arranged on the box body 7, and the box body 7, the box cover 4 and the bearing seat 5 form a closed space gear box; an input straight bevel gear 2 is arranged on an input shaft 1 positioned in the gear box, the input straight bevel gear 2 is a conical gear, and a ratchet one-way transmission mechanism 3 is arranged between the input straight bevel gear 2 and the input shaft 1; two output shafts 8 are respectively driven by two sides of the input straight bevel gear 2 through one output straight bevel gear 6, and the two output straight bevel gears 6 are both meshed with the input straight bevel gear 2.
The ratchet wheel one-way transmission mechanism 3 comprises three sets of pawls 31 and springs 32, a pawl return groove 11 with 3 inward recesses is formed in the input shaft 1, 3 inward recess pawl clamping grooves 21 are formed in the inner ring of the input straight bevel gear 2, when the input shaft 1 rotates anticlockwise as shown in fig. 2, the pawls 31 are clamped into the pawl clamping grooves 21 when the springs 32 are in an extending state, the input shaft 1 drives the input straight bevel gear 2 to rotate anticlockwise, when the input shaft 1 rotates clockwise, the pawls 31 are pressed down by the inner ring surface of the input straight bevel gear 2, the springs 32 are in a compression state, the pawls 31 are separated from the pawl clamping grooves 21 and return to the pawl return groove 11, and the input straight bevel gear 2 does not rotate along with the input shaft 1.

When power is input from the middle input shaft 1 in a clockwise rotation mode, the input shaft 1 cannot drive the input straight bevel gear 2 to rotate under the one-way transmission effect of the ratchet one-way transmission mechanism 3, and the input shaft 1 only idles in the input straight bevel gear 2. Therefore, no power is transmitted. The three-shaft gearbox is combined with the reducer with single-shaft output into a whole through optimized design to form an organic whole with middle input and two-side shaft output; the gearbox has the advantages of compact structure, small volume, convenient application, stable transmission, high transmission efficiency and long service life, and can simultaneously carry out variable speed operation on two devices in different rotating directions; the device can adapt to the special requirement working condition that the input direction is unique and the transmission is not carried out in the reverse direction, and meet the market requirement.
