Superfinishing oil for grooves of inner/outer ferrule of bearing

Abstract

The invention discloses superfinishing oil for grooves of an inner / outer ferrule of a bearing. The superfinishing oil is characterized by being prepared through mixing the following raw materials in parts by weight: 70-85 parts of hydrocarbon base oil, 10-29 parts of vulcanized fatty acid ester and 1-3 parts of a nonionic surfactant, wherein the distillation range of the hydrocarbon base oil is 210-245 DEG C, and the nonionic surfactant is a polyoxyethylene nonionic surfactant. According to the superfinishing oil, groove scratch resulted from tumor cutting and superfinishing is avoided, so that the qualified ratio of finished products is increased, and the noise level of the bearing is improved; due to excellent extreme pressure and cooling and cleaning capability, the superfinishing oil can be applied to the finishing of bearing grooves, cutting tumors and scratches resulted from finishing are avoided, and the quality of finishing is improved.

Description

technical field [0001] The invention relates to the technical field of bearing processing, in particular to an ultra-finishing processing oil for grooves of inner and outer rings of a bearing. Background technique [0002] Utilizing oilstone to perform ultra-fine grinding on the grooves of the inner and outer rings of the bearing can reduce the roundness, waviness and roughness of the grooves, remove the surface metamorphic layer formed during groove grinding, improve the surface bearing area and lubricating effect, and enable The surface layer of the groove has residual compressive stress, etc., and the above effects are the basic requirements for the inner and outer rings of low-noise deep groove ball bearings. However, the super-finishing machining oil for the inner and outer raceways of the bearings currently used has the problem of not being environmentally friendly. In addition, the existing ultra-finishing processing oil for inner and outer raceways of bearings has t...
