Description

Cropper tilting ring box

Technical field

The utility model is related to farming and animal husbandry harvest machinery field more particularly to a kind of cropper tilting ring box.

Background technology

Reciprocating cutterbar is the reciprocating cutter of cutter, and structure is simpler, and adaptability is wider.Exist at present Using more on corn mowing machine, grass harvester, grain harvester combine and maize harvesting machine.Due to reciprocating cutterbar Transport characteristics are that the convert rotational motion that engine is provided is the reciprocating motion of cutter, and transmission mechanism presses structural principle not With three kinds of toggle, swinging-ring mechanism and planetary gear mechanism etc. can be divided into, because swinging-ring mechanism is compact-sized, operating is stablized It is small with noise, it is widely used in reciprocating cutterbar, plays an important role in farming and animal husbandry harvests machine.

Swinging-ring mechanism it be wobble ring from an angle mount on wobble ring axis and by wobble ring fork rotary motion be changed into toward A kind of mechanism moved again.The axis three of the axis of wobble ring axis, the axis of wobble ring and wobble ring fork must meet at a bit, work as wobble ring When axis rotates, wobble ring does not turn, and makees spherical surface swing around its central point.When wobble ring axis rotates a circle, wobble ring is restored to raw bits It sets.In this way, rotary motion is become reciprocally swinging.

Since there are manufacturing and positioning errors, the axis of the axis of wobble ring axis, the axis of wobble ring and wobble ring fork is difficult accurate It meets at a bit, so there is the trend of axial float and swing for wobble ring fork.When the play and swing trend of wobble ring fork are restrained When, wobble ring fork and the bearing between wobble ring, wobble ring and wobble ring axis bear prodigious axial additional load, greatly shorten tilting ring box Service life.

Currently, conventional way is by improving wobble ring axis, the manufacture of wobble ring and wobble ring fork and installation accuracy, to increase pendulum The service life of ring case.But the promotion of manufacturing cost is virtually will result in, the low cost that can not adapt to agricultural machinery requires, and makes reciprocal Formula cutter with receive restrict.

Utility model content

The purpose of this utility model is to provide one kind in the case where not increasing manufacturing cost, can effectively avoid because of wobble ring Axis, wobble ring and wobble ring fork three's axis intersection error cause the cropper tilting ring box of premature breakdown.

This cropper tilting ring box provided by the utility model, include in babinet wobble ring fork, wobble ring axis and Wobble ring, the axis vertical take-off of the axis and wobble ring axis of the wobble ring fork, the wobble ring are fixed on the tip inside and suit of wobble ring fork On wobble ring axis, the wobble ring fork includes the output shaft being rotatably mounted in babinet and is connected in the output by barreled tooth flank spline The pendulum at shaft end center is pitched, the axis vertical take-off of the axis and wobble ring axis of the output shaft, and the wobble ring is packed in pendulum fork inside.

For convenience of processing and installing, the wobble ring axis includes entering spindle and is mounted in the entering spindle by flat key Inclined shaft set, the entering spindle is rotatable to be mounted in babinet, the axis of the output shaft and the axis of entering spindle Orthogonal, the rotatable inclined shaft that is sleeved on of the wobble ring is put on.

The axis of the inclined shaft set and the axis of entering spindle are arranged in 15 °~30 ° of angle.

Wobble ring fork in the utility model is spent using the split structure being combined by output shaft and pendulum fork using barreled tooth flank Output shaft and pendulum fork connection are made have axial float and swing a little between output shaft and pendulum fork, when output shaft and pendulum by key When annulate shaft, wobble ring three's axis inaccurately intersect, wobble ring axis and wobble ring are applied to axial float and swing trend on wobble ring fork Only can pass to pendulum fork, and output shaft because barreled tooth flank spline gap connection relation will not to pendulum fork play and swing trend into Row constraint, pendulum fork and the bearing between wobble ring, wobble ring and wobble ring axis are not subjected to excessive axial additional load, can effectively prolong The service life of long the utility model.The utility model is simple in structure, easy for installation, can reduce by three lines generated because manufacturing and assembling The additional load of bearing pushes away to promote service life between the wobble ring fork that the error that crosses induces and wobble ring, wobble ring and wobble ring axis The new development of dynamic reciprocating cutterbar.
