Combination of oil for pair of gear worm

Abstract

A composite oil for worm gear set contains mineral lubricating oil, at least one pour depressor and/or viscosity index improver chosen from polymethylacrylate, poly-alpha-olefin, alkylnaphthalene, etc, at least one S-contained extreme pressure agent and/or P-contained extreme-pressure antiwear agent, at least one oil agent or friction improver, at least one phenol-type or amine-type antioxidizing agent, at least one phenyltriazole or thiabiazole type metallic deactivator, and at least one poly-alcohol-ether type antiemulsifying agent.

Description

technical field [0001] The invention relates to a lubricating oil composition, more precisely a worm gear oil composition. technical background [0002] In 1948, the American Petroleum Institute (API) included worm gear oil in the classification of transmission lubricants. my country's research on worm gear oils began in 1977. At present, worm gear oils are divided into two categories: common type (L2CKE) and extreme pressure type (L2CKE / P). The quality index of ordinary worm gear oil refers to the US military MIL2L215019E specification, while the quality index of extreme pressure worm gear oil refers to the US military IL2L218486B (OS) specification. [0003] A transmission is one of the types of gear transmission used to transmit power and motion between two axes that are staggered in space. Worm gear transmission has the characteristics of small size, large transmission speed ratio, stable operation, low noise, and large output torque of worm gear, so it has been widely...
