Abstract

The invention discloses an FD bearing oil composition and a preparation method and applications thereof. The composition is composed of the following components in parts by weight: 6-8 parts of boehmite, 3-5 parts of chlorite, 1-3 parts of thulium, 1-2 parts of vinyl tri(beta-methoxy) triethoxy methylsilane, 1-2 parts of lithium 12-hydroxystearate and 80-87 parts of FD bearing oil. The prepared FD bearing oil composition can be formed into metal ceramic wearing layers with high intensity on the working surfaces of inner and outer rings of a bearing and the surface of a rolling element, so that the bearing is kept to move smoothly, the failure rate is reduced, the service life of the bearing is prolonged by more than five times, the consumption of lubricating material is saved, and the effect of environmental protection is achieved. The product raw material are easily available, the product is scientific in formula, simple in manufacture process, low in cost and good in performance. The FD bearing oil composition is used as high-speed spindle oil and sewing-machine oil in textile industry, and particularly applicable to lubricating spindle bearings of precision machine tools of which the operating temperature is more than 0 DEG C, and other high-speed sliding bearings lubricated by cycling, oil bath and oil fog, or precision rolling bearings.

Description

technical field [0001] The invention relates to an FD bearing oil composition, in particular to a precision machine tool spindle bearing suitable for lubricating the operating temperature above 0°C and other high-speed sliding bearings lubricated by circulation, oil bath, or spray, or precision rolling bearings. It is also used as high-speed spindle oil and sewing machine oil in the textile industry, belonging to the field of material technology. Background technique [0002] The performance of the bearing is determined by the design and manufacture. In terms of design, there is little difference in the level of various companies in the world, and manufacturing factors are the key factors that determine bearing performance. Different material selections, even the same selection of materials, but different processing techniques will lead to huge differences in the bearing's dimensional accuracy, rotation accuracy, vibration noise, life and reliability. [0003] Domestic bea...
