Description

Technical Field

[0001] This utility model relates to the field of coaxial reducer testing equipment, and in particular to a testing device for the drag torque of a coaxial reducer. Background Technology

[0002] Coaxial reducers, as an important power transmission device, are widely used in various industrial equipment, such as automated production lines, industrial robots, and lifting machinery. Their performance directly affects the operating efficiency, stability, and reliability of the entire equipment system. Dragging torque (also known as no-load torque or friction torque) is a key performance indicator of a coaxial reducer. It refers to the internal resistance torque required to drive the input shaft to rotate at a constant speed when the reducer's output shaft is unloaded. The magnitude of the drag torque directly reflects the reducer's transmission efficiency, internal assembly quality, and friction loss. An excessively high drag torque not only means large energy loss and low efficiency but may also indicate quality defects such as overly tight assembly, insufficient machining precision of parts, or poor lubrication.

[0003] Therefore, coaxial reducer manufacturers need to test the drag torque of coaxial reducers to determine whether there are quality problems with the products. In response to this need, this application provides a solution. Summary of the Invention
