A compound planet gear arrangement (100, 200, 300, 400) having a ring gear (no, 210, 310, 410), at least two planet gear units (120, 220, 329, 429) and a sun wheel (130, 230, 330, 430). Each planet gear unit comprise a primary planet gear (121, 221, 321, 421) with primary planet teeth meshing with the ring gear and a secondary planet gear (122,222, 322, 422) with secondary planet teeth meshing with the sun gear. The secondary planet gear is axially connected with the primary planet gear. Each planet gear unit (120, 220, 320,420) comprises a shock absorbing transmission arrangement (20) which is arranged to allow a limited elastic rotation of the second planet teeth relative to the first planet teeth.
