Description
Technical field
The utility model relates to a kind of combine running gear.
Background technology
Combine harvester caterpillar running gear and running gear system relatively have that ground pressure is little, radius of turn is little, turning is nimble and stride ditch and get over advantages such as ridge ability is strong.As shown in Figure 1, the crawler unit of combine comprises the guide rail 2 that is fixed on the frame 1 of grain header bottom and respectively by rack-mounted drive sprocket 4 of installation shaft and regulating wheel 5.Described crawler belt 3 inboards are provided with guide-track groove, and when crawler belt 3 runs to when below, this guide-track groove matches with the bottom of guide rail 2, and the rotation of crawler belt 3 is play the guiding role, and are offset about restriction crawler belt 3; Described drive sprocket 4 is arranged on the anterior of running gear and is rotated by motor driven, and drive sprocket 4 periphery radially is provided with the gear teeth, the band tooth of these gear teeth and crawler belt 3 inboards mesh with transmission of power to crawler belt 3, the power of advancing is provided for whole locomotive body; Regulating wheel 5 generally is installed in the rear portion of running gear, and with crawler belt 3 tensioning backward, the installation site of this regulating wheel 5 has certain regulated quantity, can regulate the rate of tension of crawler belt 3 whereby; In order to prevent that crawler belt 3 from changing with the height of landform deformation takes place, generally also be provided with some ground engaging stabiliser wheels 6 between drive sprocket 4 and regulating wheel 5, these some ground engaging stabiliser wheels 6 are pressed with the bottom of crawler belt 3 inboards and are touched, and prevent crawler belt 3 bottoms generation moderate finite deformation and skid.
As shown in Figures 2 and 3, rail body 21 comprise be positioned at the bottom operate portions 211 and by the upwardly extending dowel 212 in operate portions top, described dowel at grain header width transversely than operate portions in narrow many of the width of this direction, guide rail mainly is that the bottom surface of operate portions contacts cooperation with horizontal two sides with guide-track groove when guide-track groove on the crawler belt 3 cooperates.In the prior art, the guide rail operate portions generally is lower than half of whole rail body height at the thinner thickness of short transverse, and the height at operate portions top also is lower than the height of guide-track groove both sides cell wall.Since when crawler belt 3 rotates the guide rail operate portions will with the sliding friction of guide-track groove inwall, so the guide rail operate portions can be worn after long-time the use, the service life of thin operate portions is also shorter; In addition, because the thinner thickness of guide rail operate portions, so the mating surface of guide rail and guide-track groove is less, guide rail might be deviate from guide-track groove, thereby can't play guide effect.
As shown in Figure 4, drive sprocket 4 comprises the assembled portion 41 and the partition type gear part 42 that is installed on the assembled portion in the middle of being positioned at, and described gear part is provided with the some gear teeth that are uniformly distributed in the assembled portion periphery.In the prior art, assembled portion axially away from the axial outer face of the outer face of sprocket wheel installation shaft and gear part substantially in one plane.
As shown in Figure 5 and Figure 6, in the prior art, regulating wheel 5 comprise installation portion 51 in radial center, the wheel rim portion 52 of outer radial periphery and radially be connected in described installation portion and wheel rim portion between spoke plate 53, described spoke plate upper edge circumferentially is evenly distributed with some reinforcements 54 that radially are connected between described installation portion and the wheel rim portion.The axial thickness of described reinforcement is less than the thickness of wheel rim portion and installation portion, but greater than the thickness of spoke plate, and described spoke plate and reinforcement all are partial to the axial side setting of described wheel rim portion.Therefore, when the tensile force of regulating wheel transmitted between installation portion and wheel rim portion, the direction of power can be offset to some extent, made regulating wheel stressed not just, and durability degree reduces.
