Description

Technical Field

[0001] The utility model relates to the field of brazing driving, in particular to a brazing furnace driving device. Background Art

[0002] The drive system in a CAB brazing furnace generally refers to the system used to transport the workpieces into and through the brazing furnace. In a continuous CAB controlled atmosphere brazing furnace, the drive system generally includes a variable speed drive and a stainless steel mesh belt.

[0003] Specifically, the variable speed drive can adjust the speed of the mesh belt as needed to adapt to different production requirements and workpiece specifications. The stainless steel mesh belt is used to carry the workpieces and transport them from the entrance to the exit of the brazing furnace through the entire brazing process. This drive system can ensure uniform heating and stable transmission of the workpieces in the brazing furnace, thereby improving the quality and efficiency of brazing. At the same time, due to the use of stainless steel mesh belts, the system also has good durability and stability, and can adapt to the needs of long-term continuous work.

[0004] In general, the drive system of the CAB brazing furnace is an indispensable part of the brazing process, and it plays a vital role in ensuring the brazing quality and production efficiency.

[0005] However, the driving system of the existing CAB brazing furnace generally adopts a helical gear-bevel gear reducer, which has the characteristics of large reduction ratio and large torque, but the reducer is huge, occupies a large area, and has a complex structure and high cost.
