Title:
PLANETARY GEAR MECHANISM WITH FREE WHEEL MECHANISM
Document Type and Number:
Japanese Patent JP2023112389
Kind Code:
A
Abstract:
To provide a planetary gear mechanism with a free wheel mechanism which inhibits seizure of a thrust plate and enables improvement of flexibility of setting of a gear ratio.SOLUTION: A planetary gear mechanism 100 is a planetary gear mechanism with a free wheel mechanism which reduces a speed of an output of a hydraulic motor 104 to transmit the output and includes: a housing 108 which rotates with its speed reduced; a cover 128 which seals an end surface 126 of the housing; a sun shaft 132 which is splined to a motor shaft 106 of the hydraulic motor; a first sun gear 142 integrally formed with the sun shaft; a first planetary gear 144 which engages with the first sun gear; a carrier 146 which pivotally supports a shaft 148 of the first planetary gear; a thrust plate 160 which is disposed closer to the cover side than the first planetary gear and restricts movement of the carrier; a hole 164 wich is provided at the thrust plate and through which the first sun gear may pass; a maintenance hole 166 which is provided at the cover and through which the first sun gear may pass; and a plug 162 which closes the maintenance hole.SELECTED DRAWING: Figure 1
