CN104232250A - Noise-reduction lubricating oil for motors - Google Patents

Abstract

The invention relates to a noise-reduction lubricating oil for motors, which is prepared from the following raw materials in parts by weight: 10-20 parts of base oil, 1-3 parts of antiwear additive, 2-6 parts of antioxidant additive, 3-7 parts of fatty alcohol polyethenoxy ether carboxylic acid, 6-10 parts of oleoyl sarcosine octadecylamine, 4-6 parts of modified phosphate, 0.2-0.6 part of viscosity improver, 1-5 parts of pentaerythritol, 3-6 parts of vulcanized isobutylene 4-8 parts of chlorinated paraffin, 4.5-10 parts of sulfur phosphorus bis octyl primary zinc alkyl salt and 1-3 parts of hypnone. The lubricating oil can form a borderline lubricating oil film, and can greatly reduce the friction of the motor bearings to lower the noise; and meanwhile, the lubricating oil has certain cooling effect on the bearings.

Description

A kind of noise reduction lubricating oil for motor

Technical field

The present invention relates to a kind of noise reduction lubricating oil for motor.

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 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 noise reduction lubricating oil for motor, is made up of the raw material of following parts by weight:

Base oil 10-20 part, wear preventive additive 1-3 part, antioxidant additive 2-6 part, fatty alcohol-polyoxyethylene ether carboxylic acid 3-7 part, oleoyl sarcosine stearylamine 6-10 part, modified phosphate 4-6 part, viscosity modifier 0.2-0.6 part, tetramethylolmethane 1-5 part, sulfide isobutene 3-6 part, clorafin 4-8 part, the two pungent primary alkyl zinc salt 4.5-10 part of sulphur phosphorus, methyl phenyl ketone 1-3 part.

The invention has the beneficial effects as follows, 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.
