Description

A kind of forward and reverse automatic commutator

Technical field:

The utility model relates to a kind of commutator, especially a kind of forward and reverse automatic commutator.

Background technique:

At present, the mechanism of the automatic forward and reverse motion half and half of mechanical type uses very extensively, moves back and forth continuously like the planing tool on the shaping machine; Rain brush on the automobile swings back and forth, the motion etc. of pumping up and down continuously on the oil well, and these equipment adopt mechanisms such as crankrocker mechanism, crank shaper mechanism, slidercrank mechanism, cam mechanism to realize mostly; Shortcomings such as it is many that these driving mechanisms exist component, and transmission accuracy and efficient are low are particularly when movement velocity is higher; The instantaneous velocity and the acceleration change of output member are big, exist serious shock and vibration in the device, poor work stability; Efficient is low, and working life is short.

The model utility content:

The utility model provides a kind of forward and reverse automatic commutator, and it is simple in structure, and is reasonable in design; Can realize the continuous one-way rotation of input shaft, the continuous transmission of the automatic forward and reverse motion of output shaft, stable working, reliable transmission; Efficient is high, and the life-span is long, has solved the problem that exists in the existing technology.

The utility model is to solve the problems of the technologies described above the technological scheme that is adopted to be: it comprises the first half gears, the second half gears, first full-depth tooth wheel, second full-depth tooth wheel, the 3rd full-depth tooth wheel, input shaft, driven shaft and output shaft; The first half gears and second full-depth tooth wheel are fixed on the input shaft; The second half gears and the 3rd full-depth tooth wheel are fixed on the driven shaft; First full-depth tooth wheel is fixed on the output shaft; Input shaft, driven shaft and output shaft are fixed on the casing through rolling bearing, and input shaft stretches out the casing outside with an end of axle shaft, and said input shaft, driven shaft and output shaft are equilateral triangle and arrange; Said the first half gears are meshed with first full-depth tooth wheel, and said the second half gears are meshed with first full-depth tooth wheel, and said second full-depth tooth wheel is taken turns with the 3rd full-depth tooth and is meshed.

The forward and reverse automatic commutator of the utility model; Can realize the continuous one-way rotation of input shaft; The continuous transmission of the automatic forward and reverse motion of output shaft; This commutator adopts gear transmission, and not electric consumer or hydraulic pressure, pneumatic control has that simple in structure, reliable transmission, stable working, efficient are high, the advantage of long service life.

Description of drawings:

Fig. 1 is the axial unfolded drawing of input shaft, driven shaft and the output shaft of the utility model.

The structural representation that is connected with a joggle that Fig. 2 takes turns for the first half gears of the utility model, the second half gears and first full-depth tooth.

Fig. 3 is second full-depth tooth wheel of the utility model and the structural representation that is connected with a joggle of the 3rd full-depth tooth wheel.

Among the figure, 1, the first half gears; 2, first full-depth tooth wheel; 3, the second half gears; 4, second full-depth tooth wheel; 5, the 3rd full-depth tooth wheel; 6, input shaft; 7, output shaft; 8, driven shaft; 9, casing.

Embodiment:

For clearly demonstrating the technical characterstic of this programme, below through embodiment, and combine its accompanying drawing, the utility model is set forth in detail.

Shown in Fig. 1～3; The utility model comprises the first half gears 1, the second half gears 3, first full-depth tooth wheel, 2, second full-depth tooth wheel the 4, the 3rd full-depth tooth wheel 5, input shaft 6, driven shaft 8 and output shaft 7; The first half gears 1 and second full-depth tooth wheel 4 are fixed on the input shaft 6; The second half gears 3 and the 3rd full-depth tooth wheel 5 are fixed on the driven shaft 8, and first full-depth tooth wheel 2 is fixed on the output shaft 7, and input shaft 6, driven shaft 8 and output shaft 7 are fixed on the casing 9 through rolling bearing; Input shaft 6 stretches out casing 9 outsides with an end of axle shaft 7, and said input shaft 6, driven shaft 8 and output shaft 7 are equilateral triangle and arrange; Said the first half gears 1 are meshed with first full-depth tooth wheel 2, and said the second half gears 3 are meshed with first full-depth tooth wheel 2, and said second full-depth tooth wheel 4 is taken turns 5 with the 3rd full-depth tooth and is meshed.

During use; When drive device drives input shaft 6 rotates counterclockwise; The first half gears 1 on the input shaft 6 are taken turns 2 engagement driving with first full-depth tooth on the output shaft 7; Clockwise rotate thereby drive output shaft 7, the 3rd full-depth tooth wheel 5 that second full-depth tooth wheel 4 on the input shaft 6 drives on the driven shafts 8 clockwise rotates, and the second half gears 3 on this moment driven shaft 8 do not have first full-depth tooth on the gear teeth and the output shaft 7 to take turns the gear teeth meshing on 2; After input shaft 6 rotates counterclockwise 180 °; The first half gears 1 on the input shaft 6 no longer include the gear teeth meshing transmission on first full-depth tooth wheel 2 on the gear teeth and the output shaft 7; And under the engagement driving effect of second full-depth tooth wheel the 4 and the 3rd full-depth tooth wheel 5; At this moment, the gear teeth on the second half gears 3 on the driven shaft 8 begin with output shaft 7 on first full-depth tooth wheel 2 on the gear teeth meshing transmission, rotate counterclockwise thereby drive output shaft 7.After input shaft 6 rotates counterclockwise 180 ° once more; The second half gears 3 on the driven shaft 8 no longer include the gear teeth meshing transmission on first full-depth tooth wheel 2 on the gear teeth and the output shaft 7, at this moment, the gear teeth on the first half gears 1 on the input shaft 6 begin again with output shaft 7 on first full-depth tooth wheel 2 on the gear teeth meshing transmission; Driving output shaft 7 once more clockwise rotates; So alternately engagement driving has realized input shaft 6 continuous one-way rotation, the motion of output shaft 7 automatic forward and reverse each half turn.

If on the outer end of output shaft 7, install gear, move through the gear driven tooth bar again, just can realize input shaft 6 continuous one-way rotation, output shaft 7 drives automatically continuous forward and reverse the moving back and forth of tooth bar, and forward and reverse mobile distance equates.

The utility model does not detail part, is those skilled in the art of the present technique's known technology.
