Description

Technical Field

[0001] The utility model relates to the field of differentials, in particular to a split-type impact-resistant metallurgical differential. Background Art

[0002] Metallurgy refers to the extraction of metals or metal compounds from minerals. During the process of metallurgical work, metallurgical minerals need to be transported by metallurgical mine cars. When the metallurgical mine cars are in use, the wheels of the metallurgical mine cars need to be connected by differentials. The differential refers to a mechanism that enables the left and right (or front and rear) drive wheels to rotate at different speeds.

[0003] The differential is mainly composed of left and right half-axle gears, two planetary gears and a gear rack. The function of the differential is to make the left and right wheels roll at different speeds when the metallurgical mining car turns or drives on uneven roads, that is, to ensure that the driving wheels on both sides perform pure rolling motion. The differential is installed to adjust the speed of the left and right wheels. The split differential is also a type of differential.

[0004] However, when the existing split differential is used, it is not conducive to the impact buffering of the bottom of the split differential. When passing through an uneven ground, it is easy for the bottom of the split differential to collide with the uneven ground. If the impact position is not buffered when the split differential is impacted, it is easy for the split differential to be vibrated and impacted, which is easy to cause damage to the split differential, which is not conducive to the use of the split differential.

[0005] Therefore, we propose a split-type differential for impact-resistant metallurgy. Utility Model Content
