Abstract

一种高效节能、节材无级调速钢筋切断机是由交 流无级调速电动机驱动，通过调节电动机的转速，即 可实现钢筋切断机从0到额定转速的无级或有级调 速。
这种高效节能、节材无级调速钢筋切断机，省去 了传统钢筋切断机变速机构中的大部分变速齿轮，具 有结构简单，加工方便，工作效率高，无功损耗低等特 点。

Description

本发明涉及到的是建筑施工领域里大量应用的钢筋加工机械。
目前公知的各种钢筋切断机，其转速的调节都是通过机械变速机构来实现的有级变速，其变速结构复杂，加工困难，成本高，重量大，工作过程中，由于变速困难，不能很快地将原动机的运动速度改变为工作机构所需的运动速度，电机的耗电量和无功功率损耗很大。此外，生产加工变速所需的各种齿轮也要消耗大量的优质钢材，造成极大的经济浪费。
本发明提出的高效节能、节材无级调速钢筋切断机，就是为了解决上述弊端而提出的。
本发明的原理是这样的：将交流无级调速电动机应用在钢筋切断机上，通过控制调节无级调速电动机的转速，即可实现钢筋切断机的无级调速。
本发明提出的高效节能、节材无级调速钢筋切断机，不仅实现了钢筋切断机的无级调速，提高了工作效率，降低了电能损耗，而且由于变速部分省去了传统变速部分中的大部分齿轮，使之结构简单，便于制造，节省了大量的优质钢材，从而达到高效节能、节材的目的。
本发明是这样来实现的：交流无级调速电动机（1）固定在减速器（2）上，无级调速电动机轴通过齿轮副（3）带动偏心轴（4），活动刀片（5）实现从0到额定转速的无级调速，从而达到调速的目的。

Claims (2)

1、高效节能、节材无级调速钢筋切断机，其特征在于：交流无级调速电动机(1)，通过齿轮副(3)与减速器输出轴(4)啮合；驱动齿轮(5)、齿轮(6)，带动活动刀片(7)移动；通过控制、调节调速电动机(1)来实现钢筋切断机从0到额定转速的无级或有级调速。
2、如权利要求1所述，交流无级调速电动机也可以是交流有级调速电动机。
