Abstract
The utility model discloses an installation structure of a balance shaft. The installation structure of the balance shaft comprises a balance shaft support, a balance shaft installation hole formed in the balance shaft support and the balance shaft arranged in the balance shaft installation hole. The installation structure of the balance shaft is characterized in that a cylindrical pin hole is formed in the balance shaft support, the cylindrical pin hole penetrates through the balance shaft installation hole, a through hole is formed in the balance shaft, the through hole is matched with the cylindrical pin hole, a cylindrical pin is arranged in the through hole and in the cylindrical pin hole after the balance shaft is installed in the balance shaft installation hole, and the two ends of the cylindrical pin are fixedly connected with the balance shaft support. The installation structure of the balance shaft has the advantages that assembling difficulty is reduced, production efficiency is improved, and the structure is quite simple.
Description
Technical field
The utility model relates to a kind of truck balance shaft, relates in particular to a kind of balance shaft mounting structure.
Background technology
In prior art, in order to guarantee the safety in utilization of balance shaft, when balance shaft is installed, needing to adopt the large magnitude of interference to assemble is arranged on balance shaft in the balance shaft mounting hole, if because the magnitude of interference is less, in use, the flush fit relation of balance shaft and balance shaft mounting hole easily lost efficacy, but this large magnitude of interference assembling mode causes fitting process very difficult, and efficiency of assembling is very low.
The utility model content
For the problem in background technology, the utility model proposes a kind of balance shaft mounting structure, comprise balance shaft support, be arranged at the balance shaft mounting hole on balance shaft support and be arranged at the interior balance shaft of balance shaft mounting hole, its improvement is: be provided with cylinder pin hole on described balance shaft support, cylinder pin hole runs through the balance shaft mounting hole; Be provided with through hole on described balance shaft, through hole and cylinder pin hole coupling; Balance shaft arranges a straight pin after being arranged in the balance shaft mounting hole in through hole and cylinder pin hole, captive joint with balance shaft support in straight pin two ends.
Through after aforementioned improved, straight pin can in use carry out the rigidity restriction to the position of balance shaft, even less balance shaft and the balance shaft mounting hole of also can not occurring of the magnitude of interference between balance shaft and balance shaft mounting hole coordinates the problem that lost efficacy, thereby make balance shaft and balance shaft mounting hole can adopt slight interference amount assembling mode to assemble, reduce assembly difficulty, enhance productivity.
Useful technique effect of the present utility model is: simplify assembly difficulty, enhance productivity, structure is very simple.
