Hinge structure for engineering machinery
The invention discloses a hinge structure for engineering machinery. The hinge structure comprises a first assembly component and a second assembly component which are matched with each other, and a pin shaft penetrates through the first assembly component and the second assembly component; the pin shaft is in clearance fit with the first assembly component and the second assembly component, and elastic elements for limiting axial movement of the pin shaft are arranged at the two ends of the pin shaft respectively. The pin shaft can rotate in the radial direction and move left and right in the axial direction, the maximum stress area of the pin shaft can be changed in a self-adaptive mode due to movement of the pin shaft, the maximum stress area and the abrasion area of the pin shaft can be changed along with rotation and left-right movement of the pin shaft, the problem that the hinge pin is broken due to the fact that the hinge pin fixing area is subjected to the maximum stress and abrasion damage is solved, and meanwhile, the problem that a hinge pin cover plate cracks or a fastener is broken due to the fact that the axial stress of the hinge pin is too large is solved. The pin shaft is easy to machine and manufacture, easy to implement and low in cost; special toolings and tools are not needed in mounting operation; outdoor maintenance and replacement are easy and convenient; and the use, maintenance and replacement costs are effectively reduced.
本发明公布一种工程机械用铰接结构。包括相配合的装配部件一和装配部件二，销轴穿设在装配部件一和装配部件二中；销轴与装配部件一和装配部件二采用间隙配合，销轴的两端分别设置有限制销轴轴向移动的弹性元件。销轴能够沿径向位置旋转和轴向左右位移运动，销轴的最大受力区域会因销轴的运动而发生自适应改变，销轴的最大受力区域和磨损区域会随着销轴的旋转和左右运动而变化，避免了销轴固定区域受最大应力和磨损损伤而造成销轴断裂问题，同时解决了因销轴轴向应力过大造成销轴盖板开裂或紧固件断裂问题。本发明销轴加工制造简单易实施、成本低；安装操作无需特殊工装、工具；户外实施保养、更换简单便捷；有效降低使用和维护更换成本。
