Description

一种减振油锯 技术领域
本发明属于油锯的技术领域，涉及一种减振油锯。
背景技术
二冲程发动机作为大部分手持式园林工具的动力源，输出做功的同时产生的振动也比较大，对如何有效提高对操作者操作时的舒适性，是该类工具长期研究及提高的方向。
当二冲程发动机点燃开始工作，每分钟高达一万多转的速度进行运转，必须采取有效的减振措施消减发动机产生的各种振动，使其尽可能少的传递到附属部件。目前手持式油锯多采用橡胶减振，通过将多个减振橡胶安装于发动机曲轴箱以及后手把上，然后用螺栓固定于后手把以及发动机曲轴箱的相应位置，发动机高速运转产生的振动源经过多个减振橡胶的有效缓冲后，传递至外部环境或操作者时，其振动能量及振动频率实现较大幅度地降低。
众所周知，橡胶减振有两大弊端，橡胶在受外力挤压时，消减振动的能力倍数级放大，对于振动源输出较大的工具，其减振效果不佳。再者，在随着使用时间的加长，橡胶件容易老化和磨损，工具在后续的使用中振动频率会急剧加大。
目前油锯的橡胶减振方式为多个橡胶减振件布置于曲轴箱，但曲轴箱并非整个振动源的唯一来源，根据内燃机振动原理获知，动力源中的气缸也是振动产生的重要振动源。油锯的产生的振动主要是动力组传递至外部，而与之直接相连的需要手持去把控操作的部件是前手把及后手把，常规油锯采用的减振方 式如附图5所示，多个橡胶缓冲块9分别布置于曲轴箱4的前端两侧以及后端的上下两侧，但因橡胶缓冲块9的特性以及位置的设计，其无法最大程度的消减二冲程发动机所释放出的振动。
发明内容
本发明针对现有技术的不足，提供了一种减振油锯，将减振机构分别分布于发动机的主要振动源处，使振动能量更加均匀的被分配，并更加有效的被消减，使操作的舒适性得到大幅度的提升。
为解决上述技术问题，本发明的目的通过下述技术方案得以实现：
一种减振油锯，包括与动力总成连接的前把手和后把手，所述动力总成包括气缸体和曲轴箱，所述减振油锯上设置有至少三组减振机构，减振机构一设置在气缸体的上侧；减振机构二布置于气缸体轴线的前侧；减振机构三布置于气缸体轴线的后侧，所述减振机构包括螺旋弹簧。
在上述的一种减振油锯中，所述减振机构一包括螺旋弹簧一，所述螺旋弹簧一的一端锁附于气缸体的安装孔处，另一端安装于弹簧座一上，所述弹簧座一通过紧固螺栓一锁附在前把手上。
进一步的，所述气缸体的安装孔处设置有内螺纹，螺旋弹簧一通过紧固螺栓一与内螺纹螺接形成锁附，所述弹簧座一上设置有螺纹柱，弹簧座一通过螺纹柱旋入螺旋弹簧一，弹簧座一内还设置有与紧固螺栓一螺接的内螺纹。
在上述的一种减振油锯中，所述减振机构二包括螺旋弹簧二，所述螺旋弹簧二的一端锁附于后把手前端的安装处，另一端安装于弹簧座二上，所述弹簧座二通过紧固螺栓二锁附于曲轴箱右侧。
进一步的，所述后把手前端的安装处设置有螺纹柱，所述弹簧座二上亦 设置有螺纹柱，所述螺旋弹簧二的两端分别旋入两个螺纹柱中，所述弹簧座二内还设置有与紧固螺栓二螺接的内螺纹。
在上述的一种减振油锯中，所述减振机构三包括螺旋弹簧三，所述螺旋弹簧三的两端分别安装在弹簧座三上，所述弹簧座三通过紧固螺栓三分别锁附于曲轴箱左侧后部及后把手的安装孔处。
进一步的，所述弹簧座三的一端设有与螺旋弹簧三连接的螺纹柱，另一端设有与紧固螺栓三连接的通孔，紧固螺栓三穿过通孔后分别与曲轴箱左侧后部及后把手的安装孔螺接。
在上述的一种减振油锯中，所述螺旋弹簧三的轴线与油锯放置的水平线成一夹角，所述夹角的范围为90°-120°。
在上述的一种减振油锯中，所述减振机构三的安装面与油锯的中心面平行。
在上述的一种减振油锯中，所述减振机构三的左右两侧设置有橡胶减振件。
本发明和现有技术相比，具有如下有益效果：
1、本发明针对手持式园林工具油锯，通过重新认识二冲程发动机振源传递的振动能量扩散状况，设计了全新减振元件的结构形态，将减振机构分别设置在主要振动源处，使振动能量更加均匀的被分配，并更加有效的被消减，使操作的已经舒适性得到大幅度的提升。
2、本发明的主要减振机构采用螺旋弹簧，不仅具有更好的减振效果，而且避免了橡胶件的老化和磨损，延长了减振机构的使用寿命。
3、本发明改进了减振机构三的安装方式，使螺旋弹簧三的轴线与油锯放 置的水平线成一夹角、减振机构三的安装面与油锯的中心面平行。相比于现有技术中的垂直安装方式，本发明的安装方式更有利于消减反复抬压时振动源传递的减振。
