Trace lubricating oil for high-speed motor bearing and preparation method of trace lubricating oil

Abstract

The invention belongs to the technical field of lubricating oil and particularly relates to trace lubricating oil for a high-speed motor bearing and a preparation method of the trace lubricating oil. The trace lubricating oil is characterized by being prepared from the following raw materials in percentage by weight: 79-90 percent of low-viscosity alpha-olefin, 9-20 percent of octocapric propylene glycol ester and 1-2 percent of dibutyl phosphate, wherein the low-viscosity alpha-olefin is any one of PAO2, PAO4, PAO6, PAO8 or PAO10. Compared with the prior art, the trace lubricating oil disclosed by the invention has the advantages that better lubricating property and extreme pressure anti-wear property are obtained; and by matching with a trace lubricating device, trace amount of lubricating oil can meet the lubricating requirement of the high-speed motor bearing, so that the service life of the high-speed motor bearing is effectively prolonged, the design speed of the high-speed bearing is effectively increased and the important significance for the development of the high-speed motor is realized.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, in particular to a low-quantity lubricating oil for high-speed motor bearings and a preparation method thereof. technical background [0002] Traditionally, high-speed motor bearings are lubricated with grease or high-viscosity lubricating oil. However, under high-speed rotation above 8,000 revolutions per minute, the heat dissipation of the bearing is not timely due to friction and heat, which causes the bearing to burn out easily. The most direct The consequence is that the design speed of my country's motor bearings is difficult to exceed 10,000 rpm. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, adopt a new formula to prepare the micro-lubricating oil suitable for use in the micro-lubrication system of high-speed motor bearings, and cooperate with the micro-lubrication device to replace the original traditiona...
