Abstract

一种风扇叶片,其特征在于:叶片横向有两次弯折,使叶面除弯折区外呈三个平面,且近导边弯折处的折向和近随边弯折处的折向相反。叶片的两次弯折,提高了叶片的刚性,且使排风量增大。本扇叶特别适用于排风量要求较大的扬谷扇。

Description

风扇叶片
本实用新型涉及一种轴流风扇叶片。
现有的薄板型风扇叶片其叶面为一光滑曲面,这种结构的叶片相对来说,加工较复杂、送风量较小,且刚性不高。
本实用新型的目的在于提供一种送风量大、刚性好的风扇叶片。
本实用新型的目的由以下技术方案实现:
本风扇叶片为薄板结构,叶片横向有两次弯折,使叶面除弯折区外呈三个平面1、2、3,且近导边弯折处的折向与近随边弯折处的折向相反。
叶片横向的两次弯折,可使叶片的刚性提高,近随边处弯折后,增大了送风面,使排风量增大。
本实用新型结构简单、加工方便、扇风效果好。
附图说明:
图1为本风扇叶片实施例一的结构图;
图2为本风扇叶片实施例二的结构图。
本叶片采用薄钢板弯折制成,图1中,叶片的梢端与根部等宽。图2中,叶片的梢端宽、根部窄。在叶片的根部钻有固定孔4,通过固定孔4用螺栓可将本叶片固定在叶轮的轮毂上。本扇叶特别适用于排风量要求较大的扬谷扇。

Claims (3)

1、风扇叶片,为薄板结构,其特征在于:叶片横向有两次弯折,使叶面除弯折区外呈三个平面(1)、(2)、(3),且近导边弯折处的折向与近随边弯折处的折向相反。
2、根据权利要求1所述的风扇叶片,其特征在于:叶片的梢端与根端等宽。
3、根据权利要求1所述的风扇叶片,其特征在于:叶片的梢端与根端不等宽。
