Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
The left and right direction of the left and right and drawing in literary composition is consistent.
Shown in Fig. 1-9, the anti-reverse mechanism carrying on a kind of agricultural machinery power transmission shaft, it has flange welding jaw 1, at described flange welding jaw, be welded with hollow tubular parts 2, these hollow tubular parts have an openend that deviates from flange welding jaw, and hollow tubular parts have cylindric inner chamber and circumferentially adopt rectangular array mode to be provided with four tippers at internal chamber wall, this tipper has the bearing of trend inclined plane consistent with hollow tubular parts rotation direction and a blocking surface of being located at inclined plane tail end; Be installed on the internal spline adapter sleeve 3 of hollow tubular parts, its periphery wall is circumferentially provided with two anti-rotation component assembling grooves corresponding with tipper, as we know from the figure, fitting recess is selected is that the mode of annular array is arranged, the elastic component 4 that this fitting recess is provided with a locking plate 5 and locking plate top is located to hollow tubular parts inwall.At hollow tubular parts, near the inwall of its openend, be circumferentially provided with jump ring mounting groove, at jump ring mounting groove, be provided with jump ring 7 and the ring washer 6 between jump ring and internal spline adapter sleeve, at jump ring, away from ring washer one side, be provided with the back-up ring 12 that is sheathed on internal spline adapter sleeve, three steel balls 8 that the front end sleeve of described internal spline adapter sleeve is provided with spring 9 and is circumferentially located at internal spline adapter sleeve front end, front end at internal spline adapter sleeve is also provided with axle caulking groove, be positioned at axle caulking groove and be provided with axle card 11, at axle Ka11Chu, quick elastic cover 10 is installed.
For ease of whole mechanism is carried out to oil injecting lubricating operation, at hollow tubular parts, be provided with oil nozzle 13.
Referring to Fig. 3, shown in 6, for obtaining desirable anti-reverse effect, mutually vertical between the blocking surface of described tipper and inclined plane is comparatively desirable, when the front end of locking plate enters tipper and finally terminates in blocking surface from the top on inclined plane, due to the elasticity lifting effect of flexible of locking plate, so make internal spline adapter sleeve to realize and being rotated counterclockwise at hollow tubular parts.
Referring to Fig. 6, the inner circle of the inclined plane of described tipper and hollow tubular parts is tangent, and inclined plane enters the guide surface of tipper as locking plate, can be arranged to linear structure, also can curved structure.
Due to internal spline adapter sleeve locking is needed to two fulcrums, so the quantity of described tipper setting is the twice of fitting recess quantity, such as in figure 3, tipper setting be four, fitting recess is set to two.
Referring to Fig. 8, described locking plate has a front end face coordinating with blocking surface, locking plate near fitting recess bottom one side have one for elastic component, install and utilize elastic component can be by the inner fovea part of locking plate front end lifting, the height of the blocking surface of described tipper is less than the height of locking plate front end face.
Referring to Fig. 9, described elastic component is the bow type spring of a sheet, and the bearing of trend of bow type spring is identical with the axial direction of internal spline adapter sleeve.
Referring to Fig. 5, flange welding jaw welds together with the pipe with tipper, with endoporus of pipe (being cylindric inner chamber) of tipper with jump-ring slot, after the whole installations of pipe interior section are entered, with jump ring 7 all anti-reverse mechanisms core (internal spline adapter sleeve 3, elastic component 4, locking plate 5) be fixed in pipe, in pipe, play anti-reverse effect, the tipper that has four an angle of 90 degrees at round tube inner wall, on internal spline adapter sleeve cylindrical, also there are two fitting recess, one bow type spring 4 and locking plate 5 is respectively installed in these two fitting recess, when active force is rotated counterclockwise, when two grooves in four grooves of two fitting recess of internal spline adapter sleeve and the pipe of interior pore area tipper overlap, the elastic force of bow type spring 4 is the left end jack-up of locking plate 5, the locking plate part of left end is just harmonious with the groove of round tube inner wall and stuck, the groove of round tube inner wall is to locking plate one resistance, play and drive whole power transmission shaft rotation, thereby reach the effect of transmitting torque, when active force turns clockwise, basic and round tube inner wall is tangent according to one side of round tube inner wall groove an angle of 90 degrees, when active force works, inwall is to locking plate one pressure, when pressure is greater than the elastic force of bow type spring, bow type camber of spring, locking plate sinks in the fitting recess of internal spline adapter sleeve completely, when active force turns clockwise, namely at grain header when retreating, internal spline adapter sleeve rotates in pipe, can not transmitting torque, so just reach and when grain header retreats, promptly cut off power, to realize the needs of combining operation.
After whole anti-reverse mechanism assembles, directly coordinate installation with the Hooke's joint of power transmission shaft one end, anti-reverse mechanism is a part for power transmission shaft, be exactly quite to rely on this power transmission shaft that carries anti-reverse mechanism to connect with being connected with grain header end at engine, in conventional art, the product that engine is connected with grain header has a common power transmission shaft to add a unidirectional anti-reverse clutch again.The power transmission shaft that carries anti-reverse mechanism is not through connection repeatedly, and after installing, noise and vibration reduce, and reach the effect of an optimum transfer moment of torsion.
The foregoing is only preferred embodiment of the present utility model, protection domain of the present utility model is not limited in above-mentioned embodiment, and every technical scheme that belongs to the utility model principle all belongs to protection domain of the present utility model.For a person skilled in the art, some improvement of carrying out under the prerequisite that does not depart from principle of the present utility model, these improvement also should be considered as protection domain of the present utility model.
