Abstract
The utility model discloses a driving device of a cutter. The driving device of the cutter comprises a transmission box body, wherein an input shaft and a rotating arm are installed on the transmission box body. A fixed gear ring is fixedly installed on the transmission box body, the input shaft and the rotating arm are perpendicular to each other, and the input shaft is connected with the rotating arm through a gear pair in transmission mode. The rotating arm is arranged inside the fixed gear ring, a crank is rotatably installed on the rotating arm, a planetary gear is fixedly installed on the crank, and the planetary gear is meshed with the fixed gear ring. The lower end of the crank is a power output end, and the movement track of the lower portion of the crank is a straight line. The driving device of the cutter is high in transmission efficiency and reliability, small in size and convenient to install.
Description
Technical field
The utility model relates to a kind of transmission device, especially relates to a kind of for the drive unit on the harvester cutting.
Background technique
Along with country continues to increase the support dynamics of agricultural, the demand of reaper is increasing, the cutter of reaper drives and adopts tilting ring box to drive at present, the tilting ring box structure of using on the existing market is eccentric shaft structure, exist volume very much not to be convenient to install, transmission power is little, and rate of fault is high, and working life is short.
The model utility content
Technical problem to be solved in the utility model is: a kind of cutter drive unit is provided, and transmission efficiency is high, and reliability is high, volume is urinated in installation.
For solving the problems of the technologies described above, the technical solution of the utility model is: the cutter drive unit, comprise transmission case body, be rotatablely equipped with input shaft on the described transmission case body, pivoted arm, be installed with fixed gear ring on the described transmission case body, described input shaft is vertical with pivoted arm to be arranged, described input shaft and pivoted arm are in transmission connection by gear pair, described pivoted arm is arranged in the described fixed gear ring, be rotatablely equipped with crank on the described pivoted arm, be installed with planetary pinion on the described crank, described planetary pinion is meshed with described fixed gear ring, and clutch end is that the underpart of described crank and the movement locus of underpart are straight line.
Preferably, described gear pair is two intermeshing bevel gears, and described two bevel gears are fixedly installed in respectively on described input shaft and the pivoted arm.
Adopted technique scheme, the beneficial effects of the utility model are: owing to designed above-mentioned cutter drive unit, the number of teeth of the fixed gear ring in the utility model and planetary pinion engagement and fixed gear ring is 2 times of the planetary pinion number of teeth, the distance of diaxon is half of planetary pinion standard pitch diameter on the crank, so transmission efficiency is higher.The vibration of this drive unit is little, the fault that can reduce the noise of ceding of Taiwan system and cause because of vibration, and this drive unit more can guarantee the straight line motion of cutter with respect to the eccentric shaft tilting ring box simultaneously, has reduced the rate of fault of cutter, reliability is high.This drive unit is less with respect to eccentric shaft tilting ring box volume, more is convenient to install.
Description of drawings
Accompanying drawing is the utility model embodiment's structural representation;
Wherein: 1, transmission case body; 2, input shaft; 3, pivoted arm; 4, crank; 5, fixed gear ring; 6, bevel gear; 7, planetary pinion; 8, needle bearing; 9, wheel hub; 10, belt wheel; 11, deep groove ball bearing; 12, tapered roller bearing.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in drawings, the cutter drive unit, comprise transmission case body 1, be rotatablely equipped with input shaft 2, pivoted arm 3 on the transmission case body 1, be installed with fixed gear ring 5 on the transmission case body 1, input shaft 2 and pivoted arm 3 vertical settings, input shaft 2 and pivoted arm 3 are in transmission connection by gear pair, in the present embodiment, gear pair is that 6, two bevel gears 6 of two intermeshing bevel gears are fixedly installed in respectively on input shaft 2 and the pivoted arm 3.Pivoted arm 3 is arranged in the fixed gear ring 5, is rotatablely equipped with crank 4 on the pivoted arm 3, is installed with planetary pinion 7 on the crank 4, and planetary pinion 7 is meshed with fixed gear ring 5, and clutch end is that the underpart of crank 4 and the movement locus of underpart are straight line.
In the present embodiment, the bearing that is installed on crank 4 two ends is respectively needle bearing 8 and deep groove ball bearing 11, and the bearing that is installed on pivoted arm 3 two ends is tapered roller bearing 12, and certainly, the bearing that is installed on pivoted arm 3 two ends also can adopt deep groove ball bearing.Crank 4 is connected with planetary pinion 7 by spline mechanism or singly-bound mechanism, and input shaft 2 is connected with wheel hub 9 by spline mechanism, is installed with belt wheel 10 on the wheel hub 9.
The number of teeth of the fixed gear ring 5 in the present embodiment and planetary pinion 7 engagements and fixed gear ring 5 is 2 times of the planetary pinion number of teeth 7, and the distance of diaxon is half of planetary pinion 7 standard pitch diameters on the crank 4, so transmission efficiency is higher.The vibration of this drive unit is little, the fault that can reduce the noise of ceding of Taiwan system and cause because of vibration, and this drive unit more can guarantee the straight line motion of cutter with respect to the eccentric shaft tilting ring box simultaneously, has reduced the rate of fault of cutter, reliability is high.This drive unit is less with respect to eccentric shaft tilting ring box volume, more is convenient to install.
The utility model is not limited to above-mentioned concrete mode of execution, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within the protection domain of the present utility model.
