Description

Technical Field

[0002] Application No. 201821241871.2 provides a reducer housing that is easy to cool and dissipate heat. The working component of the reducer is installed in the installation cavity of the housing. When working, the working component rotates, and the water pump delivers the coolant into the cooling cavity through the delivery pipe and the coolant input pipe. The heat dissipated by the installation cavity is absorbed by the heat dissipation blade. The establishment of the cooling cavity and the heat dissipation blade increases the area of ​​the installation cavity that contacts the coolant, and the coolant in the cooling cavity absorbs the heat of the installation cavity, thereby increasing the working efficiency. At the same time, through the inspection cavity, the inspection cavity The gear meshing part can be directly observed at the top of the upper case. The meshing condition of the transmission parts working in the installation cavity can be checked through the inspection cavity, and lubricating oil can be injected into the box. Then the coolant returns to the coolant storage tank through the coolant output pipe. The cooling plate installed in the coolant storage tank cools the coolant after absorbing heat, so that the coolant can be recycled. At the same time, the purity and oil level of the oil in the oil reservoir are regularly observed through the observation window. When the oil is turbid or the oil level exceeds a certain height, the oil drain plug is opened to release the accumulated oil in the oil reservoir;

[0003] However, the coolant storage tank of the device causes the reducer box to be too large, making it inconvenient to store the reducer; however, the existing reducer has a cooling fan at the input end and a protective cover at the input port; but since the cooling fan rotates with the input shaft, the cooling fan is greatly damaged, so the cooling fan needs to be regularly inspected and maintained, but since the installation and removal of the protective cover is time-consuming and labor-intensive, the inspection is inconvenient and the practicality is poor.
