Abstract
L'invenzione concerne la disposizione di supporto, ovvero supportazione, di una ruota portante (4), in particolare per un attrezzo per l'utilizzo in agricoltura, in giardinaggio oppure nella manutenzione di prati, per esempio un rasaerba (1). La cassa (2) dell'apparecchio è movibile sul terreno per mezzo di parecchie ruote portanti (4). La disposizione di supporto delle ruote portanti (4) comprende rispettivamente due cuscinetti a sfere con spallamenti obliqui (7), i cui anelli esterni (16) sono associati alla bussola di supporto (6) della ruota portante (4) ed i cui anelli interni (17) sono serrati reciprocamente su uno spinotto di supporto (8) associato alla cassa (2), laddove tra gli anelli esterni (16) e gli anelli interni (17) sono disposte sfere rotolanti in piste di scorrimento. Per migliorare la durata di una siffatta disposizione di supporto, si prevede di produrre di
