Embodiment Construction

[0025] Embodiments according to the present invention will be described with reference to the drawings. Here, a case where the planetary carrier according to the present invention is applied to a single-pinion type planetary gear mechanism will be described. like Figure 1 to Figure 3 As shown, the planetary carrier 4 according to this embodiment is configured to include a pair of holding members 10, 20 that hold the pinion shaft 6 from both sides in the axial direction L, and the planetary carrier 4 Planetary gear mechanism 1 constituting a single pinion type (refer to Figure 4 ) of the rotation element. That is, the planetary carrier 4 is used for the planetary gear mechanism 1 . Furthermore, the planetary carrier 4 according to the present embodiment is configured such that the number of parts and the number of joining steps can be suppressed, and the outer peripheral gear 21 is provided. Hereinafter, the configuration of the carrier 4 according to the present embodime...

Abstract

A planetary carrier having a reduced number of parts and a reduced number of joining steps is provided. The planetary carrier is provided with a pair of holding members for holding a pinion shaft (6), which supports a pinion gear (5), from both sides in the axial direction (L). A first holding member (10), which is one of the pair of holding members, is provided with connection sections (11) extending in the axial direction (L) toward a second holding member (20), which is the other of the pair of holding members. The second holding member (20) is a circular plate-shaped member and has an externally toothed outer peripheral gear (21) formed integrally with the outer periphery of the second holding member (20). The connection sections (11) and connection joint sections (22) provided in the second holding member (20) at positions on the inner side (R1) of the outer peripheral gear (21) in the radial direction are joined together.

Description

technical field [0001] The present invention relates to a planetary gear carrier used in a planetary gear mechanism and fixed to rotate integrally with a rotating shaft. Background technique [0002] As the prior art of the planetary carrier as described above, there is, for example, the technology described in Patent Document 1 below. Hereinafter, in the description of this background art, symbols and names of Patent Document 1 are appropriately described within parentheses and cited. Patent Document 1 describes a planetary carrier that includes a pair of holding members (carrier plates 21, 22) that hold a pinion shaft (pinion shaft PS) from both sides in the axial direction, wherein the pinion shaft supports a small The gear (pinion P1 ) and the pair of holding members are joined via a connection portion (plate beam 23 ) formed on one holding member (plate 22 ). [0003] In addition, the structure of Patent Document 1 adopts a structure in which an outer peripheral gear ...
