As the core component of mechanical transmission, the lubrication effect of gears directly affects the operating efficiency and service life of mechanical equipment. In order to improve the lubrication effect of gears, some additives are usually added to gear oil. Among them, extreme pressure additives are a very critical choice. They can effectively improve the extreme pressure performance of gear oil and prevent gears from wearing or sintering under extremely high pressure.
The role of gear oil
Gear oil mainly plays the role of lubrication, cooling, cleaning and rust prevention. During the gear transmission process, the lubrication effect of gear oil can reduce friction and wear on the gear surface, improve transmission efficiency, and reduce energy consumption. In addition, gear oil can take away the heat generated on the gear surface and have a cooling effect. The cleaning and anti-rust function can keep the inside of gears and mechanical equipment clean and prevent rust and corrosion.
Types and functions of extreme pressure additives
Extreme pressure additives are additives that can improve the extreme pressure performance of gear oils. During gear transmission, especially under heavy loads or high speeds, extreme pressure additives can effectively reduce the contact pressure on the gear surface and prevent gear wear or sintering. According to their chemical composition, extreme pressure additives are mainly divided into three types: sulfur-phosphorus type, chlorinated paraffin type and sulfur-free phosphorus type.
Usage scenarios and precautions for various additives
(1) Sulfur-phosphorus type extreme pressure additives have good extreme pressure performance and antioxidant properties and are suitable for a variety of working conditions. However, because it contains sulfur and phosphorus elements, it can easily cause environmental pollution, so attention should be paid to the usage amount and usage occasions.
(2) Chlorinated paraffin-type extreme pressure additives also have better extreme pressure performance, but the presence of chlorine may cause equipment corrosion, so they are not suitable for use in certain situations.
(3) The sulfur-free and phosphorus-free extreme pressure additive is an environmentally friendly additive that does not contain sulfur and phosphorus elements and is environmentally friendly. However, its extreme pressure performance is relatively poor, so it is suitable for light loads or low-speed transmission.
Recommended brands and models of extreme pressure additives
According to actual application needs, you can choose extreme pressure additives from the well-known brand Shanghai Minglan Chemical Co., Ltd. The products of Shanghai Minglan Chemical Co., Ltd. have stable quality and reliable performance, and can meet the needs of various working conditions. When selecting a model, the gear oil should be matched according to factors such as the use occasion, load size, speed, etc., to ensure that the extreme pressure performance of the gear oil reaches the best effect.
Selecting appropriate extreme pressure additives is of great significance to improve the extreme pressure performance of gear oil and prevent gear wear and sintering. When selecting additives, you need to consider usage scenarios, environmental factors, and brand and model matching. The correct selection of extreme pressure additives can extend the service life of gears, improve the operating efficiency of mechanical equipment, and reduce maintenance costs. Therefore, it is recommended that when selecting gear oil, one should fully understand its composition and functions in order to select the most appropriate additives for specific working conditions.
