Patent number: 11236816Abstract: An aspect of a carrier for a planetary gear device includes two separate endplates that fit together using a snap-fit assembly. Retention protrusions extending from one of the endplates snap-fit into corresponding recesses on the other endplate to assemble the carrier. The shape of the recess is configured to reduce or eliminate any tendency for loads to force retention protrusion to disengage from the recess, which may result in loss of structural integrity of the carrier.Type: GrantFiled: May 12, 2021Date of Patent: February 1, 2022Assignee: ENPLAS CORPORATIONInventors: Kazuki Yamada, Koki Hisai

Patent number: 11236814Abstract: 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.Type: GrantFiled: October 21, 2020Date of Patent: February 1, 2022Assignee: ENPLAS CORPORATIONInventors: Koki Hisai, Kazuki Yamada
