Selection steps of FYH general rolling bearing with house

FYH housed rolling bearings are available in various forms and specifications. Therefore, in order to select the most suitable bearing with a block for the purpose of mechanical design, it is necessary to conduct a comprehensive study on the operating conditions of the mechanical structure, the performance requirements of the block with a block, the specifications, marketability, and economy of the components surrounding the assembly. Whether the choice is correct or not will make a big difference to the life of the bearing. Table 3.1 shows the selection steps of rolling bearings with general housing. Selection steps of general rolling bearings with houses: Selection steps Considered use conditions for research projects Relevant information 1 Form selection Vertical seat flange type slider seat ring seat bracket seat Mechanical structure, installation space, installation related dimensions, etc. 2 Shaft diameter and Selection of diameter series Bearing inner diameter 8 to 140 mm Diameter series 0, 2, X, 3 Required bearing life, load acting on the bearing, rotational speed, etc. 4 Bearing life (P26) 5 Bearing load (P29) 6 Allowable rotational speed ( P36) 3 Countermeasures for the environment Triple sealing ring product with dust cover Purification series Stainless steel series Ceramic series FYH blower for high speed with housing for bearing Environment (dust, muddy water, moisture, medicine, etc.), rotation speed, etc. 2 Forms (P8) ( P21) 6 Allowable speed (P36) 4 Countermeasures against temperature 9 Shaft and base design (P43) 14 Use (P59) 5 Selection of shaft fixing method With set screw With fastener With eccentric fixed ring Rotation speed, load conditions, usability, etc. 2 Type (P8) 14 Use (P59) Selection of 6-axis Dimensional tolerances Stepped shafts Machining of set screw seats for shafts Response to shaft expansion and contraction Rotational speed, load conditions, bearing temperature, etc. 2 Forms (P8) 7 Allowable rotational speed (P36) 9-axis and base design (P43) 14 Use (P59) 7 Study of bearing housing strength Load conditions, load direction, presence or absence of impact, etc. 8 Study of grease replenishment Time environment, importance of machinery, bearing temperature, grease life, etc. 9 Research environment for maintenance inspection, importance of machinery, bearing temperature, grease life, etc. Cast iron cast steel steel plate regular inspection Replenishment of grease 2 Form (P8) 8 Strength of FYH bearing housing (P38) 14 Use (P59)
