Classification, and requires the use of the fan bearing

Fan fan high temperature bearing high temperature bearing briefly description 1, yaw, heat is analyzed. studying bearing such a high temperature usually bearing component design, single row four-point contact ball bearing or double row wheel heat four-point contact ball bearing turntable temperature, shall meet the following technical requirements: fan bearing the high temperature mechanical properties, yaw temperature has little bearing clearance, is analyzed. studying bearing temperature or high temperature four-point contact ball bearing clearance 'negative space' design, and channel designed to deal with, can bear high axial load and torque load. Yaw gear components is to choose the appropriate material, the modulus, tooth surface hardness of contour, in order to ensure life and matching between the drive gear. At the same time, the heat treatment take targeted measures, in order to improve the strength of the tooth surface, high temperature resistant bearing has good wear resistance and impact resistance. For fan is exposed in the wild in China, so the sealing material for high temperature bearing performance has its own strict requirements, must be of high temperature bearing seal form can manage and to optimize the design of the teaching, so as to guarantee the high temperature bearing life and fan life the same. Fan has been packed in more than 50 m even hundreds of meters of altitude, installation is expensive, so we must have a very high reliability and general development requires 20 years life, coupled with the high temperature bearing industrial structure is more complex, so high to the requirement of design technology. High temperature fan bearing briefly 2, high temperature high temperature bearing spindle bearing spindle is commonly centering roller bearing high temperature, and a large cone Angle double row taper roller bearing high temperature, most of the impeller shaft is supported by two centering roller bearing high temperature. Due to the impeller main high temperature bearing by large load, and the shaft is very long, easy to deformation, therefore requires high temperature bearing must have a good centering performance. 3. Gear box of high temperature bearing gear box has a variety of high temperature bearing, including deep groove ball bearings, cylindrical roller bearings, cylindrical roller roller bearing, double row tapered roller bearing, spherical roller bearings, thrust spherical roller bearings and four-point contact ball bearing. Gearbox bearing temperature is mainly composed of gearbox gear lubricating oil, lubricating oil multiple metal particles, high temperature can significantly affect bearing life, need to use special heat treatment process, make the track surface compressive stress, scroll to the particle impurity sensitivity, reduce the channel to improve bearing life at high temperature. According to the working conditions of high temperature bearing, also need to bearing structure is used in high temperature optimization, high temperature bearing, in order to improve the processing, further improve the bearing performance of the high temperature. High temperature fan bearing briefly three bearing high temperature generator, generator for temperature bearing adopts the cylindrical roller bearing high temperature and high temperature deep groove ball bearing. Through the structure of these two kinds of high temperature bearing design, processing technology to improve cleanliness, production process control and optimization of the involved components to reduce the high temperature of bearing vibration noise, make high temperature bearing has good low noise performance. The previous: use of lubrication system technology can solve the bearing heating next up: none
