Detect the vibration speed value and acceleration value of complete sets of bearings according to national standards. ZWZ also has the domestic leading ultra-large 4-band bearing vibration measurement and 6.4 angular contact ball bearing vibration and spherical roller bearing vibration. The vibration can be compared with deep groove ball bearings, cylindrical roller bearings or according to user requirements. The specific speed must be specified when ordering. and vibration value requirements. Temperature rise measurement system, the bearing inner diameter range is 120~200mm. ZWZ has a large-scale wave spectrum analysis system. The system measures the maximum bearing outer diameter of 500mm. It covers the vibration detection of most super-large motor bearings and can conduct quality inspection on the vibration and temperature rise trends of the bearings. assessment.

Measuring the waviness of parts to ensure the vibration value of complete sets of bearings. ZWZ ferrule raceway spectrum analyzer is an important means of quality control of motor bearing processes. It can not only control the quality of raceway waviness, but also perform spectrum analysis on complex waveforms. Analysis to provide basis for quality analysis and equipment adjustment. The working performance and reliability of rolling bearings largely depend on the bearing material properties. Rolling bearings need to maintain high-speed, high-precision rotation while repeatedly bearing large stresses on the contact surface between the ring and the rolling element. For this reason, the materials of the rings and rolling elements are required to have a certain hardness related to the load-bearing capacity, rolling fatigue resistance under rolling contact and different lubrication conditions, wear resistance, and dimensional stability. More non-metallic inclusions can easily cause fatigue cracks. Therefore, the fewer non-metallic inclusions, the cleaner the material and the longer the life of the rolling bearing.

Rolling bearing rings generally use high carbon chromium bearing steel. For bearings subject to high impact loads and alternating bending stresses, carburized steel is used. High carbon chromium bearing steel is the most widely used in rolling bearings. It adopts the overall quenching method, and both the surface and the core can be hardened. In recent years, due to the continuous improvement of the quality of bearing steel, the oxygen content and non-metallic inclusions have been reduced through vacuum degassing treatment, and the material properties have been greatly improved. For long-life, high-reliability bearings, electroslag redissolved bearing steel with higher purity can also be used. The heat treatment process of ZWZ rolling bearing rings and rolling elements ensures that the bearings are dimensionally stable within 120°C. The cage is used to separate the rolling elements to prevent direct contact between adjacent rolling elements, thereby reducing friction and heat generation during operation. Keep the distance between rolling elements equal so that the load is evenly distributed and the stiffness is stable. It can keep the rolling elements of separable bearings from falling off and can also be used to guide the rolling elements. The cage can also serve as a grease reserve to improve bearing lubrication.

ZWZ motor bearing cages can be roughly divided into stamped cages, metal solid cages, nylon cages, etc. Under special high-temperature working conditions, high-temperature tempering treatment is required for the rings and rollers. The bearing rings need to undergo special processes. The operating temperature after heat treatment is S0 – the bearing rings have been subjected to high-temperature tempering treatment, and the working temperature can reach 150℃. S1——The bearing ring has been tempered at high temperature, and the working temperature can reach 200℃. S2——The bearing ring has been treated with high temperature tempering, and the working temperature can reach 250℃. S3——The bearing ring has been treated with high temperature tempering, and the working temperature can reach 300℃. S4——The bearing ring has been treated with high temperature tempering, and the working temperature can reach 350℃.
