摘要： Into a raceway groove formed between outer and inner races, there are incorporated a plurality of rolling elements of which outside diameters serving as the rolling contact surfaces thereof each has a curvature in the axial direction as well and also each of which has a radius smaller than the radius of the raceway surfaces of the outer and inner races. The rolling elements are arranged in such a manner that the mutually adjoining rolling elements cross each other alternately and also that the outside diameters of the respective rolling elements are always contacted at two points with the raceway surfaces of one race and the raceway surfaces of the other race.

摘要： The wireless sensor adds identification information peculiar to respective sensor modules to detection data of vibration, temperature, and so on, detected by the sensor modules respectively. The wireless sensor transmits the detection data with the identification information as a signal through a communication unit by radio waves. On the other hand, the management apparatus receiving the signal classifies and files the detection data on the basis of the identification information included in the signal. Then, the monitoring system is designed to make the management apparatus manage a plurality of wireless sensors attached to movable shafts of processing machines or the like.

摘要： The rolling bearing with a built-in motor includes a bearing part including an inner ring, an outer ring and a plurality of rolling elements, and a motor part including a stator and a rotor for driving and rotating the inner and outer rings of the bearing part with respect to each other. In the rolling bearing, the bearing part includes a first bearing ring having a cylindrical-shaped inner fixing portion formed in one end face of the inner ring so as to be coaxial therewith, and a second bearing ring having a cylindrical-shaped outer fixing portion formed in one end face of the outer ring so as to be coaxial therewith. When viewed in the radial direction of the rolling bearing, the stator and rotor are interposed between the inner fixing portion of the first bearing ring and the outer fixing portion of the second bearing ring.

摘要： When an information provision program is implemented, an input screen is displayed on a display section (step 101). A specific designation number is input (step 103), and one or plural bearing performance indexes are selected (step 107). When bearing performance indexes are selected, bearing service conditions which are required depending on the bearing performance indexes are input. Then, performance calculation programs corresponding to selected bearing performances are activated (steps 110-1, 110-2, . . .), and obtained calculation results are simultaneously displayed.
