Abstract

The invention belongs to a cultivator driving box for an agricultural machine, and essentially relates to a micro cultivator driving box with a differential. Operators frequently perform forcible turning by physical force during field operation and labor intensity is high because a few micro cultivators in the current agricultural machine market are not provided with steering devices; and operation machines and tools cannot be transported and become idle and useless after busy season. The micro cultivator driving box with the differential comprises a box body, a gear, the differential, left and right half shafts, a half shaft housing, a bearing and the like. During operation, the micro cultivator driving box effectively performs coordinated steering mainly by the differential, and turns easily, neatly and handily; after a small drag box is arranged, the operation machines and tools can be transported in spite of a far or near field; and the micro cultivator driving box can be used as a transportation tool in slack season.

Description

A kind of tiller driving box with diff

Technical field: the invention belongs to a kind of cultivator driving box of field machine, it comes down to a kind of tiller driving box with diff.

Background technology: 1WG4.0-105FC-Z and 1WG6.3-105FC-Z two tiller design uniqueness, compact conformation, high efficiency receive praises from customers.But owing to lack steering hardware, lean on the operator frequently to force to turn with muscle power entirely during little farming industry, labour intensity is very big; And be difficult to transport operation facility at random, the busy farming season is just idle useless later.

The present invention levies above-mentioned blemish in an otherwise perfect thing is studied, and provides a kind of with diff, the left and right sides semiaxis steering hardware as the tiller driving box, and operation is lightly nimble when reaching little farming industry; Turn to freely, work efficiency is high, and labour intensity is low; Simultaneously can wear little shape and drag case; Be convenient to transport operation facility at random, can also serve as transportation means during slack season, bring into play the purpose of agricultural machinery returns of investment to greatest extent.

For reaching above-mentioned purpose; The present invention has designed following technical scheme: stem gear [1] and gear [2] leak-tight joint; Link to each other with casing [5] by bearing [3], bearing [4]; There are planetary wheel [10] and planetary wheel [12] to mesh and be installed in the differential casing [8] with the left half axle gear [9] of band female splines, the right axle shaft gear [11] of band female splines respectively on the compensating-gear shaft [13] of diff [30]; Be fixed on outer gear ring [6] of differential casing [8] and stem gear [1] engagement by bolt [7]; Be fastenedly connected with bolt [23] and casing [5] with left half axle end cap [22] by bearing [14], bearing [25]; The right axle shaft [20] of band male splines is packed into together with bearing [16], bearing [18], rotary lip seal circle [19] and is fastenedly connected by bolt [15] and casing [5] interior closely linking to each other with the right axle shaft gear [11] of band female splines of right axle shaft sleeve pipe [17], and the left half axle [29] of band male splines is packed into together with bearing [27], bearing [26] and rotary lip seal circle [28] and is fastenedly connected by bolt [24] and left half axle end cap [22] interior closely linking to each other with the left half axle gear [9] of band female splines of left half axle sleeve pipe [21].

Compared with prior art, the present invention makes steering hardware because of selecting diff, left and right sides semiaxis for use, has following beneficial effect: at first; Operator when the ploughing and weeding operation need be turned is as long as stir handgrip gently; Planetary wheel in the diff is rotation in time just, drives corresponding parts and makes the actv. turning action, accurately realizes operator's turning intention; Again the operator does not frequently force to have turned with muscle power, has really reduced labour intensity; Simultaneously, can with configuration drag case transport operation facility together at random, again the gradation of hand push has been carried pickaback, fully effectively utilizes the quality time of busy farming season; And can also serve as transportation means during slack season, a tractor serves several purposes realizes that agricultural machinery invests due economic benefit.

The specific embodiment: the implementation process of the tiller driving box of following specific descriptions band diff

When tiller carries out the straight line operation; The change speed gear box corresponding gear torsional forces be delivered to gear [2] back drive with its close-connected stem gear [1] bearing [3], bearing [4] support and the condition that links to each other with casing [5] under when rotating, drive to be engaged with and to be fastened on also to drive by bearing [14], bearing [25] and casing [5] bonded assembly diff [30] when gear ring [6] on the differential casing [8] rotates and together rotate by bolt [7].At this moment the right axle shaft [20] that is fastened on the splined of adorning bearing [16], bearing [18], rotary shaft lip seal [19] in the right axle shaft sleeve pipe [17] on casing [5] right side by bolt [15] closely links to each other with the right axle shaft gear [11] of band female splines; The left half axle [29] that the left half axle end cap [22] that is fastened on casing [5] left side by bolt [23] is gone up the splined of adorning bearing [26], bearing [27], rotary shaft lip seal [28] in the fastening left half axle sleeve pipe [21] of useful bolt [24] closely links to each other with the left half axle gear [9] of band female splines, and diff [30] drives the operation of corresponding supporting operation facility completion straight line when together rotating.Tiller is accomplished planetary wheel [10] and the not rotation of planetary wheel [12] on the compensating-gear shaft [13] that is installed in the straight line operation process in the differential casing [8], but together revolves round the sun with diff [30].

When tiller is turned operation; The change speed gear box corresponding gear is delivered to gear [2] back to torsional forces and drives with its close-connected stem gear [1] and link to each other at bearing [3], bearing [4] support and with casing [5] when rotating in the state; Driving is engaged with and is fastened on gear ring [6] rotation on the differential casing [8] by bolt [7], also drives simultaneously by bearing [14], bearing [25] and together rotates with casing [5] bonded assembly diff [30].After the operator sends the turning job instruction; Because the resistance of inboard work tool is big when turning; The resistance of outside work tool is little; When turning each other under the preceding topic condition of medial and lateral, when driving planetary wheel [10] and planetary wheel [12] rotation on the compensating-gear shaft [13], the right axle shaft gear [11] of the left half axle gear [9] of band female splines and band female splines revolves round the sun with the line of centers of the right axle shaft [20] of the left half axle [29] of diff [30] strip winding spline and splined again.The rotation of planetary wheel [10] and planetary wheel [12] reduces the rotating speed of inboard work tool, and the rotating speed of outside work tool increases, and the added value of a side just in time is exactly the reduction value of opposite side.Like this; The right axle shaft [20] that is fastened on the splined of adorning bearing [16], bearing [18] rotary shaft lip seal [19] in the right axle shaft sleeve pipe [17] on casing [5] right side by bolt [15] closely links to each other with the right axle shaft gear [11] of band female splines; The left half axle end cap [22] that is fastened on casing [5] left side by bolt [23] is gone up by the left half axle [29] of adorning the splined of bearing [26] bearing [27] rotary shaft lip seal [28] in the fastening left half axle sleeve pipe [21] of bolt [24] and is closely linked to each other with the left half axle gear [9] of being with female splines; And the left and right sides semiaxis that diff [30] together rotates is accomplished tiller turning operation when corresponding supporting operation facility rotate because of planetary wheel rotation formation different rotating speeds drives respectively; Turn to freely, the operator is handy.
