no. 1 Embodiment approach

[0103] figure 1 The tapered roller bearing assembly device 90 of the first embodiment is shown. The tapered roller bearing assembly device 90 includes: a tube 20 that stores a plurality of tapered rollers 1 filled from above in a stacked state in the inner cavity 20a; A plurality of tapered rollers 1 supplied from the tapered roller supply unit 30 are supplied downward; The pipe 20 and the tapered roller supply unit 30 constitute a tapered roller supply device 10 that supplies the tapered rollers 1 to the cage 2 . In addition, the tapered rollers 1 are filled in the tube 20 so that the small-diameter portion is located below, that is, on the leading (downstream) side. In addition, the diameter of the hollow hole 20 a of the pipe 20 is set to be slightly larger than the diameter of the large diameter side of the tapered roller 1 .

[0104] The tapered roller supply part 30 comprises: a base 32, which is in the direction of gravity ( figure 1 In the Z direction) perpendicu...

no. 2 Embodiment approach

[0132] Next, a tapered roller bearing assembly device according to a second embodiment of the present invention will be described. The tapered roller bearing assembly device of this embodiment differs from the first embodiment in the configuration of the outer guide plate 60 .

[0133] Such as Figure 11 ~ Figure 13 As shown, in the outer guide plate 60 of the present embodiment, the convex portion 65 is formed radially inward from the tip of the rod-shaped portion 61 . The convex portion 65 has a guide surface 65 a radially opposed to the small-diameter portion of the tapered roller 1 , and the guide surface 65 a is located radially outward from the cage 2 and is a portion corresponding to the outer peripheral surface of the cage 2 . conical shape.

[0134] In such a configuration, when the cage 2 and the tapered roller 1 are rotated around the central axis C, the guide surface 65a of the convex portion 65 of the outer guide plate 60 guides the small-diameter portion of the...

Abstract

A tapered roller bearing assembling device comprises: an inner jig (58) for guiding the large-diameter section of a tapered roller (1), which has been supplied to the inside radially of a pocket section (6), from the inside radially toward the outside radially; and an outer jig (60) for pressing the small-diameter section of the tapered roller (1), which has been supplied to the inside radially of the pocket section (6), from the outside radially toward the inside radially. With a retainer (2) and the tapered roller (1) rotated about the center axis (C) by a retainer placement section (50), the inner jig (58) and the outer jig (60) rotate the large-diameter section of the tapered roller (1) toward the pocket section (6) about the point of contact between the small-diameter section of the tapered roller (1) and the pocket section (6) of the retainer (2), thereby mounting the tapered roller (1) into the pocket section (6).

Description

technical field [0001] The invention relates to a tapered roller bearing assembly device and a tapered roller bearing assembly method. Background technique [0002] Conventionally, as a method of assembling tapered roller bearings, such as Figure 14 and Figure 15 As shown, a method of applying centrifugal force to the tapered roller 101 and incorporating it into the pocket portion 121 of the cage 102 (see Patent Document 1). More specifically, first, the tapered rollers 101 dropped by gravity into the tube 105 are arranged in an annular shape on the inner side in the radial direction of the pocket portion 121 of the cage 102 . Next, the tapered rollers 101 and the cage 102 generate centrifugal force by rotationally driving the lower die 104 by the pulley 144 . Then, the tapered rollers 101 are driven into the pockets 121 of the cage 101 by utilizing the generated centrifugal force to be inserted. [0003] Additionally, if Figure 16 As shown, in the tapered roller bear...
