摘要： Provided is a production line that includes a conveying section (2) for conveying a plurality of pallets (8 and 8) along a loop-shaped circulation route, a workpiece setting section (3) for setting workpieces on the pallets (8 and 8), a setting-position measuring section (4) for measuring setting position of the workpiece on the pallets (8 and 8), a production process performing section (5) for performing one or multiple production processes at each of a plurality of locations on the circulation route for the workpieces on the pallets (8 and 8), and a workpiece extracting section (6) for extracting workpieces for which the production processes have been performed from the pallets (8 and 8). At least two of the production processes in the production process performing section (5) are performed while taking into account the setting positions of the workpieces on the pallets (8) measured by the setting-position measuring section (4).

摘要： The present invention relates to a grease application device in which a tip-side inclined surface of a nozzle 28 is made to closely face worm wheel teeth 11 of a shaft-mounted worm wheel 9 while rotating the shaft-mounted worm wheel 9 by means of a drive unit 12. At this state, the grease application device is configured to apply liquid grease from a tip-side opening of the nozzle 28 to the worm wheel teeth 11 of the shaft-mounted worm wheel 9 and to apply the grease while pushing the grease into concave portions of the worm wheel teeth 11. Also, the grease application device is configured to end the application of the grease at a point of time at which the shaft-mounted worm wheel has rotated one revolution with respect to the nozzle 28 after starting the application of the grease to the shaft-mounted worm wheel 9.

摘要： Provided is a bearing insertion apparatus in which a movable carriage is provided on a base placed on a floor surface in a manner of being movable in a horizontal Z-axis direction corresponding to a direction in which the movable carriage moves toward or away from a housing. In addition, an apparatus main body for supporting a rolling bearing at a distal end thereof is supported such that the apparatus main body can be freely moved, by a guide mechanism, with respect to the movable carriage in a horizontal X-axis direction orthogonal to the Z-axis direction and in a vertical Y-axis direction orthogonal to both of the Z-axis direction and the X-axis direction.
