Abstract

The invention discloses a lubricating device and a lubricating system for a high-speed rotating bearing. The device includes a rotating shaft on which a first bearing and a second bearing are arranged; A sleeve is provided; an inner spacer that rotates together with the first bearing inner ring and the second bearing inner ring is arranged between the side of the first bearing inner ring and the second bearing inner ring; between the side of the first bearing outer ring and the second bearing inner ring An outer spacer is arranged between the sides of the outer ring of the second bearing; an oil spray nozzle for injecting lubricating oil is arranged on the outer spacer; an oil return hole for circulating the lubricating oil is arranged on the sleeve; The position of the oil injector for filling lubricating oil is provided with a vane that rotates with the rotating shaft; the system includes an oil temperature detection device, a lubricating oil filtering device, a flow detection device for oil return, and a lubrication control device; due to the use of high-speed rotating The shaft rotates at high speed at the same time, which achieves the purpose of reducing equipment cost.

Description

technical field [0001] The invention belongs to the field of mechanical equipment, in particular to a lubricating device for a high-speed rotating bearing and a lubricating system applied thereto. Background technique [0002] The speed of the electric spindle of the drilling and tapping center mainly depends on the limit speed of the spindle bearing; the lubrication of the bearing is the premise to ensure that the high-speed spindle bearing reaches the limit speed. Different speed ranges require different lubrication methods: grease lubrication and oil mist lubrication. In order to increase the limit speed of the bearing, reduce the temperature rise of the bearing, and improve the service life of the bearing; high-speed electric spindle bearings with a speed above 15000r / min need oil mist lubrication. At present, imported oil mist generators are mainly used to meet the requirements of spindle oil mist lubrication; the structure is relatively complex, the processing requirem...
