Problems solved by technology
[0002] The market segmentation of agricultural machinery harvesters commonly includes wheat harvesters, corn harvesters, rice harvesters, cotton harvesters, potato harvesters, etc. According to the working characteristics of the harvesters themselves, some engines have a large front-end output power. When the force acting on the small head of the crankshaft is biased or mostly to one side, the impact on the small head of the crankshaft is relatively large, which is likely to cause fracture failure

Embodiment Construction
[0013] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.
[0014] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations thereof such as "includes" or "includes" and the like will be understood to include the stated elements or constituents, and not Other elements or other components are not excluded.
[0015] Such as figure 1 As shown, a balance structure of a crankshaft small end according to a preferred embodiment of the present invention includes: an additional pulley 1 for the crankshaft, a belt 2 and a pulley 3 . The additional pulley 1 of the crankshaft is fixedly connected with the small end of the crankshaft; the pulley 3 is connected with the additional pulley 1 of the crankshaft through the belt 2, and the pull...

The invention discloses a balance structure of a crankshaft small head. The balance structure comprises a crankshaft additional belt wheel, a belt and a belt wheel. The crankshaft additional belt wheel is fixedly connected with the crankshaft small head; the belt wheel is connected to the crankshaft additional belt wheel through the belt, and the belt wheel is of an automatic spring structure; andthe belt wheel outputs torque through the automatic spring structure, and the belt transmits reverse pretightening force to the crankshaft additional belt wheel. In this way, the balance structure ofthe crankshaft small head reduces force borne by the crankshaft small head, effectively balances partial tension of the crankshaft small head, and accordingly reduces the fracture failure rate causedby large tension impact on the crankshaft small head.
Description
technical field [0001] The invention relates to the technical field of engines, in particular to a balance structure of a small head of a crankshaft. Background technique [0002] The market segmentation of agricultural machinery harvesters usually includes wheat harvesters, corn harvesters, rice harvesters, cotton harvesters, potato harvesters, etc. According to the working characteristics of the harvesters themselves, some engines have a large front-end output power. When the force acting on the small head of the crankshaft is biased or most of it is biased to one side, the impact on the small head of the crankshaft is relatively large, which is likely to cause fracture failure. [0003] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to tho...
