Abstract

The invention discloses quenching oil dedicated to small module gears and a preparation method of quenching oil, and belongs to the technical field of metal heat treatment. The quenching oil comprises the following components in parts by mass: 35 to 40 parts of refined base oil, 2 to 3 parts of a cooling compound agent, 0.5 to 0.8 part of a blackening compound agent, 0.3 to 0.7 part of a brightening agent, 0.6 to 0.8 part of a surfactant and 0.04 to 0.06 part of an antioxidant. The quenching oil is specially developed for the small module gears of which the module is 1 mm or below, the optimal utilization temperature is 100 to 110 DEG C, the fluidity of the quenching oil is good in the temperature range, the cooling velocity for the small module gears is moderate, protective films are formed on the surfaces of the gears through automatic blackening during quenching, the secondary coating antirust treatment on the surfaces after heat treatment is reduced, the resources are saved, the procedure is reduced, and the efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of metal heat treatment, and more specifically relates to a special quenching oil for small modulus gears and a preparation method thereof. Background technique [0002] A gear is a mechanical element with teeth on the rim that can continuously mesh to transmit motion and power. The application of gears in transmission has appeared very early. At the end of the 19th century, the principle of generative gear cutting method and special machine tools and cutting tools using this principle appeared one after another. With the development of production, the stability of gear operation was paid more attention. Gears and their gear products are important basic parts of mechanical equipment, and the main transmission parts of most complete sets of mechanical equipment are gear transmissions. China's gear industry is developing rapidly, and the scale of the industry is constantly expanding. During the "Eleventh Fiv...
