In order to solve the defects in the prior art, the utility model aims to provide a drive box body flange connection structure.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a drive box flange draw bail, its includes the box main part, be equipped with in the box main part and be used for the fixed flange of box installation, flange includes first flange and second flange, first flange is parallel to each other and the interval sets up on the junction of box with the second flange, the diameter of first flange is greater than the diameter of second flange, and first flange setting is equipped with first connecting hole and second connecting hole in the outside of second flange on the first flange, is equipped with the third connecting hole on the second flange, and the diameter that second connecting hole and third connecting hole coaxial line set up and the second connecting hole is greater than the diameter of third connecting hole, be equipped with first gasket between first flange and the connecting piece that is used for installation and fixed box, be equipped with the second gasket between first flange and the second flange.
Further, the first connecting hole is arranged on the outer side of the second flange.
Furthermore, the main body of the box body is a welding piece.
Furthermore, the first connecting hole and the second connecting hole are arranged in a staggered mode.
Further, the diameter of the first flange is 1.2-1.4 times of the diameter of the second flange.
The utility model adopts the above technical scheme, first flange, the second flange is successively through bolt with drive box fixed connection, through the double flange connected mode, it is more firm to connect, first flange is different with the second flange owing to the distance from the box main part, when vibration passes to the box main part along first flange and second flange respectively, the crest and the trough of two propagation path vibrations stagger mutually, the vibration of two propagation path offsets each other, the intensity of vibration propagation to the box main part has been reduced, the production of noise has also been reduced simultaneously.
