Abstract
The utility model belongs to the application field of agricultural machinery and particularly relates to a double-cambered-surface cam gear which is a vertical shaft rotary grass-cuddling device used for a horizontal rotary grass-cuddling machine. The double-cambered-surface cam gear is used for the horizontal rotor grass-cuddling machine and composed of a vertical shaft (7), a bevel gear shaft (1), a bevel gear (11), a double-cambered-surface cam (4), a grass-cuddling arm shaft (2), grass-cuddling arm rollers (3), an upper cam cover (9), a lower cam cover (8), a bevel gear supporting frame body (10), a lower cam cover supporting frame body (5), a vertical shaft supporting base (6), connecting pieces and standard components, wherein the connecting pieces and the standard components are arranged between the vertical shaft supporting base (6) and a machine tool rising-and-falling traveling gear. The structure is simple, reliability is high, and transmission precision is high. In the rotating process of a rotor, motion trails of cuddling-harrowing spring teeth at the other end of the grass-cuddling arm shaft change along with changes of the spatial position of a curved surface track of the double-cambered-surface cam, and therefore processes of cuddling, collecting, spreading and turning of forage grass are finished.
Description
Technical field
The utility model belongs to the farm machinery application, relates to a kind of two globoid cam transmission devices of rake that horizontally rotate.
Background technique
Along with the development of pasture animal husbandry, the demand of advanced and applicable herbage production and processing machinery is constantly increased.Rake is one of machinery indispensable in the herbage harvesting process.On domestic and international market, widely used rake is the horizontal rotation type rake at present.Transmission device is the core component that horizontally rotates rake, and the rationality of its structure directly has influence on the working performance of complete machine, and the accuracy of elastic claw movement locus.But in the prior art, two globoid cam working curved surface trade shape are unreasonable, cause buck rake elastic claw movement locus inaccurate, and buck rake is large to the herbage hitting dynamics, and floral leaf loss is larger, and leak that to hug phenomenon serious.
Summary of the invention
For the problem that existing two cambered surface cam mechanism structures exist, the utility model has designed a kind of two globoid cam transmission devices that are applicable to the horizontal rotation type rake.
The utility model is achieved through the following technical solutions:
A kind of pair of globoid cam transmission device, by vertical shaft, bevel gear shaft, bevel gear, two globoid cam, hug careless arm axle, hug careless arm roller, epirelief wheel cover, lower cam cover, bevel gear supporting frame, lower cam cover supporting frame, vertical shaft bearing and and the facility link, the standard piece that rise and fall between traveling gear form; Bevel gear, bevel gear supporting frame, epirelief wheel cover, lower cam cover, lower cam cover supporting frame all are installed on vertical shaft and around vertical shaft rotary, vertical shaft and vertical shaft bearing weld and are connected to facility and rise and fall on traveling gear, bevel gear and bevel gear supporting frame link together, the bevel gear supporting frame is connected with the epirelief wheel cover, hug careless arm axle and be fixed in the middle of epirelief wheel cover and lower cam cover, two globoid cams are positioned at the epirelief wheel cover with lower cam cover and are connected with vertical shaft by flat key; Hug careless arm axle one end connection and hug careless arm roller, hug careless arm roller and be limited in two globoid cam curved surface tracks, the other end connects hugs careless arm and elastic claw, hugs careless arm roller rotary middle spindle and hug careless arm axle to be 90 °.
Two globoid cams are two limit cams, and while hugging careless arm roller motion, upper-lower position is limited, can only be along non-plane motion in two globoid cam track curved surfaces; The cam work curved surface is rectangular recess shape structure, four sections curved surfaces, consists of, and the changeover portion of large end curved surface section, small end curved sections and both sides, overlook cam, and the angle that large end curved surface section surrounds is 1/3 circumference, and the angle that the small end curved sections surrounds is 1/6 circumference; When roller was in large end curved surface section, rake kept level; When roller is in the small end curved sections, for rake and ground keep vertical active section; The pendulum that completes respectively buck rake on the changeover portion of both sides rises and puts down.
Utilize the transmission of moving between the intersecting axle of bevel gear pair implementation space; Utilize the intermittently characteristics of step motion of Space Double cambered surface cam mechanism, accurately control the movement locus of buck rake elastic claw, complete and hug grass, spread out the swath work of turning over.

Embodiment
With reference to the accompanying drawings the utility model is further described:
In accompanying drawing 1, transmission of power is to bevel gear shaft (1), bevel gear shaft (1) drives bevel gear (11) and rotates, bevel gear (11) is bolted with bevel gear supporting frame (10), be arranged on vertical shaft (7), vertical shaft (7) and vertical shaft bearing (6) weld together, and are bolted on facility and rise and fall on traveling gear; The other end of bevel gear supporting frame (10) and epirelief wheel cover (9) are fixed with bolt, and lower cam cover (8) and lower cam cover supporting frame (5) are fixed with bolt, around vertical shaft (7), rotate together; Two globoid cams (4) are connected by flat key with vertical shaft (7), are positioned between epirelief wheel cover (9) and lower cam cover (8); Hugging careless arm axle (2) is fixed by bolts between epirelief wheel cover (9) and lower cam cover (8), with epirelief wheel cover (9) and lower cam cover (8), around vertical shaft (7), rotate, hug the careless arm roller of hugging of careless arm axle (2) one ends (3) and move in the space curved surface track of two globoid cams (4), the other end of hugging careless arm axle (2) connects rake.
A kind of pair of globoid cam transmission device working principle: tractor provides power for horizontal rake, power passes to bevel gear (11) by live axle by bevel gear shaft (1), pass to epirelief wheel cover (9) and lower cam cover (8), drive the careless arm axle (2) of hugging that is connected and rotate around vertical shaft (7).Along with the motion of hugging careless arm axle (2), hugging the careless arm roller of hugging of careless arm axle (2) one ends (3) moves in the track of two globoid cams (4), track spatial position of curved surface difference due to two globoid cams (4), the movement locus of hugging the rake elastic claw of careless arm axle (2) the other end changes, and completes to hug, collect, spread out, turn over operation to herbage.
