The invention discloses an oil retaining and anti-loosening device for bearings. The device includes a fan frame, a tube in the fan frame, an oil bearing, a rotor, a stator and fan blades. The rotor includes a shaft core, and the oil bearing is sleeved on On the shaft core, the oil-impregnated bearing is sleeved in the middle tube of the fan frame, the middle tube of the fan frame is arranged at the bottom of the fan frame, the middle tube of the fan frame is located between the stator and the shaft core, and the fan blade is fixed on the rotor Above; an oil retaining structure is provided between the upper end of the fan frame middle tube and the oil bearing. An oil collecting area is formed between the annular sealing ring, the middle pipe of the fan frame, the oil-impregnated bearing, the shaft core and the fan blade HUB. The sealing ring in the oil retention structure of the present invention is an independent part, so that the winding and assembly of the motor are not affected, and the assembly of the bearing and the stator is relatively easy; the sealing ring as an independent part and the middle tube form a tight fit, so that the sealing performance is better , Effectively prevent lubricating oil leakage and fix bearings.
Description
technical field [0001] The invention relates to a heat dissipation fan, in particular to an oil retaining and anti-loosening device for bearings in the heat dissipation fan. Background technique [0002] As customers have higher and higher cost requirements, many fan bearings have been changed to oil-impregnated bearings with low unit prices under the condition of meeting customer requirements. [0003] Because the oil-impregnated bearing is an important part to support the operation of the rotor, if the lubricating oil of the bearing leaks and is lost, and the contact part between the bearing and the shaft center lacks lubricating oil lubrication, there will be friction noise. Therefore, in order to improve the bearing life of the fan, reduce friction noise, and prevent the leakage and loss of bearing lubricating oil, it is very necessary. Contents of the invention [0004] Aiming at the problems existing in the prior art, the invention provides an oil retention and anti...
