I have three gears Sun, Planet and Internal gear. I have put a Body- Ground Revolute joint for the Sun [ 1 DOF RZ ], a Body- Ground Planar joint for the Planet since it revolves arround the Sun [ 3 DOF&nbsp; UX UY RZ ] and Body- Ground Fixed joint for the Internal gear as it remains stationary [ 0 DOF].&nbsp;<\/p>\n<p><\/p>\n<p>When I ran the simulation, the planet is revolving but it is not revolving in a circular path but going out of path in the XY Plane. Also the Planet gear is not meshing properly with the Sun and Internal Gear. I tried to promote all the joints to remote points so as to use constraint equation. But I have no idea how to use the constraint equation. Can any one tell me how to do this ?<\/p>\n<p><\/p>\n<p>Thank You<\/p>\n","protected":false},"template":"","class_list":["post-44803","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["16984"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":[null],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["1471"],"_bbp_subscription":["30792"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["44803"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","178177"],"_bbp_voice_count":["2"],"_bbp_reply_count":["8"],"_bbp_last_reply_id":["117278"],"_bbp_last_active_id":["117278"],"_bbp_last_active_time":["2020-06-10 12:30:54"]},"test":"shrav007"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/44803","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/44803\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=44803"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
