Description

Technical Field

[0001] The utility model relates to the technical field related to forging processing, in particular to a high-strength main shaft forging. Background Art

[0002] Forgings refer to workpieces or blanks obtained by forging and deforming metal billets. Forgings can be divided into cold forging, warm forging and hot forging according to the temperature of the billet during processing. Cold forging is generally processed at room temperature, and hot forging is processed at a temperature higher than the recrystallization temperature of the metal billet. The difference in the complexity of the geometric structure of forgings determines that their die forging process and die design are significantly different. Clarifying the structural type of forgings is a necessary prerequisite for process design.

[0003] In the existing spindle forgings, the connection between the spindle and the transmission gear is connected by bolts, which is not strong enough. The gears are prone to loosening after long-term use, have a short service life, and are not practical. Therefore, this application provides a high-strength spindle forging to meet the needs.
