Bearing structure, mechanical part and construction device

Abstract

The invention discloses a bearing structure, a mechanical part and a construction device, and relates to the technical field of bearing. The bearing structure comprises a basic member, a bearing partand recess cavities, the basic member includes a first surface, the bearing part includes second and third surfaces arranged opposite to each other, the bearing part is connected to the basic member via surface-surface connection between the second and first surfaces, and the multiple recess cavities extending towards the first surface are arranged in at least part of the third surface at interval. Compared with a present weld seam, the surface-surface connection area can be increased substantially, a bearing force is higher, and under the same load condition, the maximal stress peak of the bearing structure is lower, the possibility of risk is lower, and the bearing structure is safer; and the recess cavities are arranged so that the bearing force can be diffused and distributed to wallsof the recess cavities, the load force is easier to bear, the safety of the bearing structure is improved, the weight of the bearing part can be reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of force bearing, in particular to a force bearing structure, a mechanical part and a construction equipment. Background technique [0002] In the design of key components, the load-bearing structure is usually formed by sticking and welding the boss, that is, the load-bearing boss is pasted and welded on the base part, and the load-bearing boss will bear the load at this time. Since the cost of attaching the welding boss is relatively low and the application occasions are wide, the method of attaching the welding boss is widely used. [0003] However, because most of the welds are fillet welds, the load-bearing area of ​​the welds is small, and the welds bear all the forces and moments, often resulting in excessive bearing stress due to the small effective bearing area of ​​the welds. For the welds of wearing parts, the leaking welds will be worn away layer by layer, and the load-bearing performance of the...

Problems solved by technology

[0004] For this reason, in order to overcome the above-mentioned defects and improve the performance of the weld seam, more expensive equipment, electrodes and welding processes are often used when attaching and welding, resulting in a high cost of attaching and welding
