Description

Technical Field

[0001] This utility model relates to the field of bearing housing technology, specifically a mud pump bearing housing. Background Technology

[0002] Mud pump bearing housings (such as F-series mud pump frame bearing housings) are typically made of integral cast steel. After machining, they are welded to the pump casing and then annealed to eliminate residual stress. The bearing housings must be preheated during the initial production process to prevent cracking caused by sudden contact between cold bearing housings and hot molten metal. More complex bearing housings can be preheated using a blowtorch or liquefied gas, or, if conditions permit, a mold temperature controller. Simpler bearing housings can be preheated using slow injection molding.

[0003] Currently, during the use of bearing housings, the bearing generates a large amount of heat during long-term operation, and this heat is transferred to the bearing housing. This heat accumulation accelerates the wear and fatigue of the bearing material, shortens the service life of the bearing, and reduces the stability of the bearing housing. Utility Model Content

[0026] The mud pump bearing housing described in this utility model is implemented by connecting the air pump 72 to a switch and a power supply. During use, the inner ring 63 of the cylindrical roller bearing 6 rotates within the sleeve 4, generating significant heat. The air pump 72 is turned on, and the incoming gas is intercepted by the dust filter 73. The air pump 72 then blows gas out through the air pipe 74. The blown gas enters the multi-ring groove 76 along the connecting groove 75 at the bottom of the sleeve 4 cavity, and then enters the discharge pipe 81 along the connecting groove 75 at the top of the multi-ring groove 76. The gas pressure causes the cover plate 85 to overcome the elastic force of the elastic spring 83, allowing the gas to be discharged smoothly. The elastic spring 83 is used to prevent the backflow of external dust and gas when the air pump 72 is not running. The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon.
