Description

Technical Field

[0001] The utility model belongs to the technical field of fan lubrication, and in particular relates to a self-lubricating bearing seat for a fan. Background Art

[0002] During the operation of fan equipment, the lubrication state of the bearing seat has a vital impact on the performance and life of the equipment. Traditional fan bearing seat lubrication methods mostly use regular manual refueling or oil bath lubrication, which has many shortcomings. First, it is difficult to achieve precise control of the lubricating oil by manual refueling. Too much or too little lubricating oil may affect the normal operation of the bearing; secondly, although oil bath lubrication can continuously provide lubrication for the bearing, under high temperature or high-speed operation conditions, the lubricating oil is easy to deteriorate and evaporate, resulting in a decrease in the lubrication effect; finally, whether it is manual refueling or oil bath lubrication, regular shutdown maintenance is required, which affects the continuous operation of the fan equipment. In order to solve the above problems and improve the lubrication effect of the fan bearing seat and the continuous operation capability of the equipment, we propose a self-lubricating bearing seat for a fan.
