Pinion assembling tray and pinion assembling device

Abstract

The invention provides a pinion assembling tray and a pinion assembling device, which can assemble a pinion to a planet carrier for operation with high efficiency so as to raise assembling productivity. The pinion assembling device (60) is composed of a conveyor (61) for conveying a pinion assembling tray (30) and a first station (S1), a second station (S2) and a third station (S3) configured along the conveyor (61). At the first station (S1), a pinion module is inserted into the planet carrier and moves, is inserted into a shaft at the second station (S2) and is in pivot joint with the shaft at the third station (S3). The pinion assembling device can independently perform pinion module positioning and shaft inserting, shorten a period and increase productivity.

Description

technical field [0001] The present invention relates to automatic assembly technology of pinions built into a planetary gear mechanism. Background technique [0002] like Figure 19 As shown, the planetary gear mechanism 100 is composed of the following parts: a sun gear 101; a planet carrier 103, which rotatably supports the planet gears 102, 102 surrounding the sun gear 101; and a ring gear 104, which surrounds the planet gears 102, 102 102 and meshes with the planetary gears 102, 102. The planetary gear 102 is also referred to as a pinion, and therefore, the planetary gear will be described later as a pinion. [0003] In this example, planet carrier 103 is restrained by brake member 105 . When the sun gear 101 rotates, the pinion gears 102 and 102 are rotated by the sun gear 101 , and the ring gear 104 is rotated by the pinion gears 102 and 102 . [0004] The carrier 103 is composed of a carrier base 111 , arm portions 112 and 112 extending from the carrier base 111 , ...

AI Technical Summary

Problems solved by technology

For example, during the insertion of the pinion assembly 123, the pressing and riveting of the shaft 108 cannot be performed

Insertion of pinion assembly 123 is not possible during press-fitting of shaft 108 and during riveting

There is a limit in productivity because multiple components cannot be moved simultaneously

[0013] In addition, from other points of view, for example, since the outer diameter of the shaft 108 is inevitably deviated, and the diameter of the hole on the carrier side is inevitably deviated, the positional alignment of the pinion assembly 123 and the shaft 108 Pressing into the carrier 103 takes time, and as a result, there is a limit to shortening the cycle
