Embodiment Construction

[0036] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0037] figure 1 The planetary carrier 10 manufactured by the manufacturing method of embodiment of this invention is shown. The carrier 10 is one of the components of the planetary gear mechanism, and rotatably supports a pinion gear that is also one of the components of the planetary gear mechanism.

[0038] The planetary gear carrier 10 has: a boss 1 with a spline groove 1s inside, a flange 2 extending radially from the lower end of the boss 1, a side wall 3 connected to the flange 2, and a side wall 3 facing the planet from the side of the planetary gear carrier 10. A seating surface 4 extending inside the gear carrier 10 and parallel to the flange 2 .

[0039] The flange 2 and the sides of the planetary gear carrier 10 are integrally formed by one part. Seat surface 4 is a surface initially on the same side as the upper surface of flange 2 , and is formed by subm...

Abstract

The invention provides a planetary gear rack and a manufacture method thereof, which are capable of reducing component number and processing steps during manufacture of a planetary gear rack, and improving yield of materials. Raw materials (W) of a side wall preset part (3p) and a seat surface preset position (4p) are alternatively configured at the surrounding of a protruding edge (2), via expansion of the seat surface preset position (4p), a seat surface (4) of a small gear is formed, and an opening (6) used for making the small gear be exposed is formed. Via stretching of the side wall preset part (3p), the side wall preset part (3p) is formed to be a side wall (3) connected with the protruding edge (2), and also the seat surface (4) is made to move toward the lower part of the protruding edge (2).

Description

technical field [0001] The invention relates to a planetary gear carrier of a planetary gear mechanism and a manufacturing method thereof. Background technique [0002] The planetary gear mechanism is composed of a sun gear, a plurality of pinion gears meshing with the sun gear, a carrier supporting the plurality of pinion gears, and a tooth pattern meshing with the plurality of pinion gears. In order to support multiple pinions from both sides, the planet carrier needs to have two parallel faces. [0003] Patent Document 1 discloses, as a method of manufacturing a planetary carrier, a method in which an annular carrier plate and a cup-shaped carrier plate are joined by electron beam welding to form the two parallel surfaces. [0004] Patent Document 1: Japanese Patent Application Laid-Open No. 58-61982 [0005] However, in the above-mentioned method, since it is necessary to machine the two carrier plates separately and then join them by electron beam welding, there is a ...
