Abstract
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.
Claims11
A carrier for a planetary gear device, comprising:
- a first endplate;
- a second endplate;
- a planetary gear shaft extending from one of the first endplate or the second endplate, wherein the planetary gear shaft is configured to receive a planetary gear;
- a recess disposed on a first surface of the first endplate, wherein the recess comprises a first wall and a second wall that extend from the first surface into the first endplate;
- and
- a retention protrusion extending from the second endplate, wherein the retention protrusion is configured to engage the recess to connect the first endplate and the second endplate,
- wherein the first wall is formed at a first angle to a first radial line extending from a center of the first endplate to an intersection of the first wall with an outer circumference of the first endplate, and
- wherein the second wall is formed at a second angle to a second radial line extending from a center of the first endplate to an intersection of the second wall with an outer circumference of the first endplate.
