Abstract

本实用新型涉及一种用于通风机叶轮的轴盘与后盘紧固连接的螺尾锥销。它包括销1和螺杆2,其特征在于:所述销1为锥销,其中靠近螺杆2端为小端。它可以非常方便地将通风机叶轮的轴盘与后盘紧固,且配合得紧密无间隙,使得叶轮在运转过程中轴盘与后盘不再出现相对的位移,提高了叶轮的使用寿命,保证了产品质量。

Description

一种螺尾锥销
本实用新型涉及一种紧固件,特别是一种用于通风机叶轮的轴盘与后盘紧固连接的螺尾锥销。
目前国内外通风机叶轮的轴盘与后盘的连接都是采用铆钉铆接的,采用这种紧固件连接时,铆钉与孔之间的铆接后不易把孔填满而存在一定的间隙,这样在叶轮运转后,轴盘与后盘有可能因铆接质量差后产生相对位移,从而破坏了叶轮出厂时的动平衡,使叶轮工作时产生振动以至使叶轮破坏或振坏轴承,而且对于铆接,工人的劳动强度大、噪音大。
本实用新型的目的在于提供一种紧固方便、紧固效果好的螺尾锥销。
本实用新型是这样实现的:一种螺尾锥销,它包括销和螺杆,其特征在于:所述销为锥销,其中靠近螺杆端为小端。
采用本螺尾锥销,可以非常方便地将通风机叶轮的轴盘与后盘紧固,且配合得紧密无间隙,使得叶轮在运转过程中轴盘与后盘不再出现相对的位移,保证了产品质量;同时锥销的强度大大高于铆钉,不易被剪切破坏,提高了叶轮的使用寿命。
下面结合附图和实施例对本实用新型作进一步说明:
图1:本实用新型实施例1的结构示意图;
图2:本实用新型实施例1的使用状态参考图。
参见图1:一种螺尾锥销,它包括销1和螺杆2,其特征在于:所述销1为锥销,其中靠近螺杆2端为小端。
参见图2:在通风机叶轮的轴盘3与后盘4上钻孔,同时配铰与螺尾锥销相同的锥度孔,即可将本螺尾锥销与孔配合得紧密无间隙。
