Abstract

"VENTILADOR ELéTRICO". Um ventilador elétrico inclui um motor (10) , duas unidades de pá de hélice (20) e duas unidades de engate (50). O motor (10) tem um eixo de motor (11) que define um eixo geométrico (L) e que tem dois segmentos de extremidade axialmente opostos (111). Cada um dos segmentos de extremidade (111) tem uma região de engate (113). As regiões de engate (113) dos segmentos de extremidade (111) são dispostas em posições regularmente opostas em relação ao eixo geométrico (L). Cada uma das unidades de pá de hélice (20) inclui um cubo (21) que é provido com luvas em um segmento respectivo dos segmentos de extremidade (111). Cada uma das unidades de engate (50) inclui um primeiro elemento de engate (51) provido na região de engate (113) de um segmento respectivo dos segmentos de extremidade (111), e um segundo elemento de engate (52) provido no cubo (21) de uma unidade respectiva das unidades de pá de hélice (20) e engatando o primeiro elemento de engate (51)."ELECTRIC FAN". An electric fan includes a motor (10), two propeller blade units (20) and two hitch units (50). The motor (10) has a motor shaft (11) which defines a geometrical axis (L) and which has two axially opposed end segments (111). Each end segment (111) has a locking region (113). The engaging regions (113) of the end segments (111) are arranged at regularly opposite positions with respect to the geometry axis (L). Each of the propeller blade units (20) includes a hub (21) that is provided with sleeves on a respective segment of the end segments (111). Each of the coupling units (50) includes a first coupling element (51) provided in the coupling region (113) of a respective segment of the end segments (111), and a second coupling element (52) provided in the hub. (21) of a respective propeller blade unit unit (20) and engaging the first engaging member (51).
