Abstract: A gear tooth for a gear of a planetary gear device may include a profile modification that alters a profile of the gear tooth to reduce wear and noise. Aspects of the profile modification may include a planar surface that connects a tip surface of the gear tooth with a first or second side of the gear tooth. Other aspects of the profile modification may include a curved surface connecting a tip surface of the gear tooth with a first or second side of the gear tooth. The gear tooth may also include non-constant profile width as measured between the first side and the second side in a gear thickness direction extending between the top and bottom surfaces of the gear. Aspects of gear teeth with either or both the profile modification and non-constant profile width may reduce tooth wear and gear noise during operation of the planetary gear device.

Abstract: Embodiments implement rotation stoppage for a contact pin at a lower cost, in which the contact pin is disposed in a socket main body to establish electrical conduction between an IC package and a wiring board. The contact pin has a barrel, an upper contact member, a lower contact member, and a coil spring. The barrel has a flange that has rotation stoppers protruding in the horizontal direction. When the contact pin is disposed in a socket main body, the rotation stoppers of the flange are brought into contact with the socket main body, whereby the barrel is restrained from rotating relative to the socket main body.

Abstract: A lubrication system for a planetary gear device includes a planetary gear mounted on a planetary gear shaft. The shaft is mounted in a shaft hole that allows the gear to rotate freely about the shaft. Lubricant reservoirs formed as voids or spaces on the inner surface of the shaft hole and outer surface of the shaft provide additional volume for lubricant to lubricate the shaft and shaft hole interface. These lubricant reservoirs extend the lifespan of the lubricant and reduce maintenance requirements of the planetary gear.
