Bearing heat treatment classification and its influence
Author:
As an important part of mechanical equipment, the quality and performance of bearings directly affect the quality and performance of the entire mechanical equipment. The heat treatment of the bearing is one of the important factors affecting the quality and performance of the bearing. In this article, we will share the classification of bearing heat treatments and their effects.
1.Classification of bearing heat treatment
Quenching
Quenching is a heat treatment method commonly used in bearing manufacturing. Quenching can make the bearing steel obtain high hardness and high strength, and improve the fatigue resistance and wear resistance of the bearing. Quenching is divided into oil quenching and water quenching. Different quenching methods will affect the hardness and structure of the bearing.
Temper
Tempering is a heat treatment method after quenching. Tempering can eliminate the stress and brittleness produced in the quenching process, improve the toughness and plasticity of the bearing, and maintain a certain hardness at the same time. Tempering is divided into three methods: low-temperature tempering, medium-temperature tempering and high-temperature tempering. Different tempering methods will affect the hardness, toughness and structure of the bearing.
Austempering
Austempering is a new type of bearing heat treatment method. Austempering can make the bearing steel obtain a uniform structure and high hardness, and at the same time have good toughness and plasticity. Austempering requires control of quenching temperature and holding time to obtain the best results.
2. The impact of bearing heat treatment
Bearing heat treatment has a significant impact on bearing quality and performance. Different heat treatment methods will affect the hardness, toughness, plasticity and organizational structure of the bearing, thereby affecting the service life and reliability of the bearing.
hardness
Hardness is an important indicator to measure the wear resistance of bearings. Quenching can increase the hardness of the bearing, but it will also reduce its toughness and plasticity. Tempering can eliminate the stress and brittleness produced in the quenching process while maintaining a certain hardness.
toughness
Toughness is an important indicator to measure the impact resistance of bearings. Tempering increases the toughness of the bearing, but also reduces its hardness. Austempering can make the bearing steel obtain a uniform structure and better toughness and plasticity.
organizational structure
Organizational structure is one of the important factors affecting bearing quality and performance. Different heat treatment methods will affect the structure of the bearing, thereby affecting its service life and reliability.
In short, bearing heat treatment is one of the important factors affecting bearing quality and performance. Manufacturers need to choose the appropriate heat treatment method according to the specific situation to improve the service life and reliability of the bearing.
