CN104212569A - Lubricating oil capable of reducing noise of motor - Google Patents

Abstract

The invention relates to lubricating oil capable of reducing the noise of a motor. The lubricating oil is produced from the following raw materials in parts by weight: 7-11 parts of ethyl acetate, 1-5 parts of trisodium phosphate, 4-9 parts of industrial red oil, 10-20 parts of synthetic base oil, 2-4 parts of trimethylolpropane, 5-7 parts of pentaerythritol, 1-3 parts of nanometer-size metal powder, 4-8 parts of sulfurized calcium alkyl phenolate, 7-9 parts of calcium alkyl benzene sulfonate, 4-7.5 parts of petroleum ether, 2.5-6 parts of antiwear additive, 3.5-8 parts of zinc dialkyl dithiophosphate, 3-8 parts of methyl acrylate and 0.5-3 parts of rust-inhibiting additive. The lubricating oil has the advantages of largely reducing the friction of motor bearings and the noise due the forming of a boundary lubricating film and cooling the bearings.

Description

A kind of motor noise-reducing lubricating oil

Technical field

The present invention relates to a kind of motor noise-reducing lubricating oil.

Background technology

Any sound that motor sends in running all can be classified as the noise of motor.These noises comprise electromagnetic noise, mechanical noise, aerodynamic noise.Mechanical noise causes primarily of rotor and bearing.Bearing is the transom of rotor and stator, and it bears the excitation of various power in motor and transmits exciting force, thus produces vibration & noise.The brush of motor and slip ring or reverser friction also can produce mechanical noise.Therefore, when electric machine rotation, usually use lubricating oil to reduce the friction of motor, reduce mechanical noise, the Working environment of protection people.

Summary of the invention

For the deficiencies in the prior art, technical problem to be solved by this invention is, provides a kind of noise reduction lubricating oil, forms borderline oil film, can reduce the friction of motor bearings significantly, reduces noise; To bearing, there is certain cooling effect simultaneously.

For solving the problems of the technologies described above, the technical scheme that the present invention takes is, a kind of motor noise-reducing lubricating oil is made up of the raw material of following parts by weight:

Ethyl acetate 7-11 part, tertiary sodium phosphate 1-5 part, industrial chilli oil 4-9 part, synthetic base oil 10-20 part, TriMethylolPropane(TMP) 2-4 part, tetramethylolmethane 5-7 part, nanometre metal powder 1-3 part, calcium sulfenyl phenolate 4-8 part, alkyl benzene calcium sulfonate 7-9 part, sherwood oil 4-7.5 part, anti-wear agent 2.5-6 part, sulphur phosphorus fourth pungent primary alkyl zinc salt 3.5-8 part, methyl acrylate 3-8 part, rust-inhibiting additive 0.5-3 part.

The invention has the beneficial effects as follows, noise reduction lubricating oil of the present invention, form borderline oil film, the friction of motor bearings can be reduced significantly, reduce noise; To bearing, there is certain cooling effect simultaneously.
