Description

Technical Field

[0001] This utility model relates to the field of speed reducer technology, and in particular to an air-cooling system. Background Technology

[0002] In existing technologies, vertically mounted gearboxes with motor flange interfaces are commonly used. However, due to their unique installation method, the uppermost bearing of the gearbox still relies on forced lubrication or oil bath lubrication. While forced lubrication provides good cooling and lubrication, it suffers from high cost and cumbersome maintenance. Oil bath lubrication, using an oil replenishment tank, is low-cost and easy to maintain, but excessively high oil levels can lead to increased heat buildup inside the gearbox, affecting operational reliability. Furthermore, the limited installation space at the bottom of a vertically mounted gearbox makes it difficult to directly place cooling structures near the heat source at the bottom, potentially impacting normal operation.
