Problems solved by technology

[0004] However, in the conventional planetary gear assembling device described above, since the pair of pinion gears face each other and are pressed together by the pair of push-out members each having an inverted splayed front end, when the tooth tops abut against each other, When a pair of pinions face each other and are pressed together in the state, the movement of both pinions other than the rotation around the axis is restricted

Embodiment Construction

[0033] Next, modes for implementing the present invention will be described with reference to the drawings.

[0034] figure 1 is a plan view showing a planetary gear assembly device 1 according to the present invention, figure 2 It is a side view showing the planetary gear assembly device 1 . The planetary gear assembly device 1 shown in these drawings is used to engage the first pinion gear 110 and the second pinion gear 120 and assemble them to the carrier 100 constituting a double-pinion planetary gear mounted in a transmission mounted on a vehicle. In addition, in the present embodiment, the first pinion gear 110 is a so-called long pinion gear, and the second pinion gear 120 is a short pinion gear that is shorter in size and lighter in weight than the first pinion gear 110 . Furthermore, three sets of the first pinion gear 110 and the second pinion gear 120 are assembled on the carrier 100 at equal intervals (120° intervals).

[0035] As shown in the figure, the plane...

Abstract

The invention provides an assembly device of planetary gear and an assembly method thereof, which can restrains the damage of addendum and mesh the first small gear and the second small gear with high precision to assembling a planet carrier. The small gear assembly system (40) of planetary gear assembly device (1) is formed by such steps: making a first small gear (41) and a second small gear (42) approaching one another towards the direction of orthorhombic with axes, making the first small gear (110) mesh the second small gear (120) in the vertical direction of the inclined state.

Description

technical field [0001] The present invention relates to a planetary gear assembling device and a planetary gear assembling method that engage a first pinion and a second pinion and assemble them on a planet carrier. Background technique [0002] Conventionally, as such a planetary gear assembly device, there is known a device that includes: a fixing unit that horizontally positions the planetary carrier; a positioning unit that is inserted into the center of the planetary carrier, and The assembly position of a pair of pinions in the planet carrier is prescribed; a pair of meshing units that holds a pair of pinions in a state where the pair of pinions face each other and their axes are shifted by a predetermined distance, and The pair of pinions are pressed together to make them mesh; the moving unit moves the meshed pair of pinions in parallel toward the planet carrier and inserts them into the planet carrier from the side of the planet carrier and makes them reach the ass...
