Description

一种锯链及链锯总成 技术领域
本发明涉及链锯技术领域，尤其是一种锯链及链锯总成。
背景技术
链锯也称油锯，是以汽油机为动力的手提锯(切割机)，主要用于伐木和造材，其工作原理是靠锯链上交错的L形刀片横向运动来进行剪切动作。
链锯总成一般包括锯链和导板，锯链包括传动片、连接片和刀片；在“专利号为202220055847X，专利名称为适用于锂电锯的锯链及锂电锯”、“专利号为202110694940.5，专利名称为一种电链锯总成”、“专利号为2020102854011，专利名称为锯链连接片、锯链及锯链传动系统”“专利号为202010256289.9，专利名称为轻型锂电池专用锯链”中均公开了锯链总成的具体结构。
在锯链工作时，需要环绕导板进行高速转动，因此锯链与导板之间的连接部位会进行磨损，当其磨损严重时会影响切割效率，因此除了刀片的磨损之外，锯链与导板之间的磨损也影响了整体锯链的使用寿命。
传统的导板和锯链均为金属材质，在锯链环绕导板工作时需要在锯链和导板之间添加润滑油来保证其工作的顺畅、减少导板和锯链之间的磨损，以及减少金属摩擦的热能，当时润滑油存在污染的问题，同时金属材质的导板和锯链重量都偏重，使得链锯笨重，不方便移动和使用者的使用。
现有技术对于非金属材料(主要复合材料)的开发，已经非常成熟，尤其是生产耐磨、耐高温的复合材料均可以达到本申请工作环境下耐高温、耐磨的标准。现有技术对于非金属材料(主要为复合材料)的开发，已经非常成熟，尤其是生产耐高温、耐磨的复合材料的技术，对于本领域技术人非常容易想到和使用的成熟材料。
譬如：1、在2017年9月12日，中国公开了专利号为201510738453.9，专利名称为“耐热耐磨PTFE塑材及其制备方法”的专利，该专利中公开的PTFE塑材的热变形温度大于300℃。
2、在2020年12月21日，中国公开了专利号为202011514390.6，专利名称为“一种耐高温、耐磨损型PEEK基体复合材料及其制备方法”的专利，该专利中公开的PEEK基体复合材料的热变形温度高达310-315℃、长期耐热指数达280℃。

本发明还公开了一种链锯总成，其特征在于：包括导板和上述的锯链，所述导板为非金属导板；所述传动片插设在所述非金属导板的导板槽内，该传动片底部的摩擦部与所述非金属导板的导板槽底部相接触且滑动配合。
作为优选：所述连接片上设有支撑部，该支撑部悬设于非金属导板上方，安装时所述连接片处的支撑部与非金属导板表面之间留有间隙；当所述非金属导板的导板槽底部与所述传动片底部的摩擦部摩擦损耗后，该传动片下沉且带着所述连接片上的支撑部搭靠在非金属导板表面、并与非金属导板表面形成滑动配合。
作为优选：所述摩擦部与导板槽槽底面的接触面为平面或弧面。平面或弧面的设置可以让传动片和导板槽底部滑动更加顺畅。
作为优选：所述传动片上摩擦部的两端分别设有倒角，该倒角的半径为0.1-10mm。
作为优选：所述传动片顶端设有向上凸起的限位块，该限位块高度低于刀片高度。本方案中每个传动片上都设置有限位块。
作为优选：与同一连接片相连接的任一传动片顶端设有向上凸起的限位块，该限位块高度低于刀片高度。由于在传动片上开设向上凸起的限位块，第一要增加生产工序，第二也提高了生产难度，第三提高制造成本，本方案中同一个连接片连接的两个传动片中的其中一个上带有限位块，这样可以减少制造成本，不需要再每一个传动片上都设置一个向上凸起的限位块。生产制作时只需要对半生产带有限位块的传动片即可。
作为优选：至少一个连接片上的支撑部处设有刮片。连接片底部的支撑部和导板周缘表面相 接触并形成滑动配合时，会出现传动片底部的摩擦部和导板槽槽底摩擦滑动配合时，导板槽底部摩擦过快，使得只有连接片底部的支撑部与导板周缘表面相接触并形成滑动配合，而传动片底部的摩擦部与导板槽底部之间没有形成摩擦滑动配合，刮片的设置是为了能够快速刮除导板周缘表面，使得传动片底部的摩擦部与导板槽底部之间持续保持摩擦滑动配合，避免上述情况发生。
作为优选：所述连接片按中心完全对称形式的结构布置，左右上下一致，其中下边各设有一个凹弧，所述刮片设置于凹弧的弧面上。
作为优选：所述连接片与导板表面之间的距离为0-1mm；所述导板槽的深度为3.16mm。本发明的有益效果是：
本申请中导板采用非金属材料，非金属材料的导板相比金属材质的导板，减轻了重量，使得链锯不在笨重方便使用者移动和使用。同时由于塑料材质的特性使得导板和锯链之间工作时不在需要润滑油的存在，便可以达到保证链锯总成工作的顺畅，也避免了润滑油污染的问题。
本申请中的链锯总成包括了两种工作状态：
第一种工作状态(也为初始工作状态)，在第一种工作状态下通过传动片底部设置的摩擦部和非金属导板的导板槽底部接触且滑动配合，实现锯链环绕导板周缘转动，在第一种工作状态下是通过传动片底部的摩擦部与非金属导板相接触摩擦、作为在锯链环绕导板周缘转动时和导板之间的受力点。
第二种工作状态是在非金属导板的导板槽底部被传动片处的摩擦部磨损到一定程度后启动，导板槽底部被磨损后导板槽的槽深变深使传动片下沉，带着连接在传动片上的连接片下降，使得连接片处的支撑部与导板周缘表面形成滑动配合，并开始承担作为在锯链环绕导板周缘转动时和导板之间的第二受力点。形成了传动片的摩擦部和连接片的支撑部均和导板形成滑动配合的第二工作状态。
其中在支撑部与非金属导板周缘表面形成滑动配合时，摩擦部依旧与导板槽底部相接触摩擦，由于传动片的两侧均设有连接片，因此非金属导板的左右两侧周缘表面均会受到支撑部的接触摩擦，因此在第二种工作状态下形成共三方受力的形式。其中支撑部的滑动摩擦减轻了摩擦部与导板槽底部的之间的力，使得摩擦部与导板槽底的使用时间更长。
通过上述的两种工作状态，在第一种工作状态下非金属导板的导板槽底面磨损一定程度后进入第二种工作状态，用支撑部去减轻和承担支撑部与导板之间的受力，使得支撑部和导板槽底面之间可以滑动使用的更加长久，进而实现延长锯链总成的使用寿命。

具体实施方式
下面结合附图对本发明作进一步描述：
实施例一：
如图3所示，本实施例提供一种锯链，布置在导板上并环绕导板周缘转动、以用于切割；锯链包括依次首尾转动式连接的传动片2和连接片3、及位于转动片1两侧的刀片4，两个传动片2之间通过位于两侧的连接片3相连接，锯链安装在导板上时，传动片2插设在导板周缘的导板槽11内；其中传动片2底部设有与导板槽11槽底滑动配合的摩擦部21，通过传动片2插设在导板槽内，且传动片2底部的摩擦部21和导板槽相互摩擦，实现锯链环绕导板周缘转动。
实施例二：
如图1-10所示，本实施例提供一种链锯总成，包括非金属非金属导板1和实施例一中描述的锯链，非金属非金属导板1上设有导板槽11，锯链通过布置在导板槽11处、以实现环绕非金属非金属导板1周缘转动；锯链包括依次首尾转动式连接的传动片2和连接片3，及位于传动片2侧部的刀片4。其中非金属非金属导板1为非金属材质制成的非金属导板1。
其中通过传动片2插设在导板槽11内，传动片2底部设有摩擦部21，该摩擦部21与导板槽11底部相接触且滑动配合，以实现锯链布置在导板槽11处、并环绕非金属导板1周缘转动。其中如图4所示传动片2底部的摩擦部21与导板槽11槽底面的接触面为平面(也可以是弧面)摩擦部21的两端分别设有倒角，该倒角的半径为R1.00mm，上述传动片2结构的设置其目的是为了能够使摩擦部21和导板槽11底面相互滑动摩擦更加顺畅，通过避免摩擦部21和导板槽11槽底过度摩擦，使导板槽11槽底磨损太快进而影响链锯总成的使用寿命。
两个传动片2之间通过位于其两侧的连接片3相连接，连接片3上设有支撑部31，支撑部31悬设在非金属导板1的上方，具体的支撑部31位于连接片3的底部该连接片3也悬设于非金属导板1上方，支撑部31与非金属导板1表面之间留有间隙6。
通过上述传动片2上的摩擦部21和导板槽11相互底部接触且滑动配合，同时连接片3上的支撑部31不与非金属导板1周缘表面相接触，形成了第一种工作状态，该种工作状态为锯链设置在非金属导板1上的初始工作状态。由于非金属导板1为非金属材质，该非金属导板1在和摩擦部21进行摩擦滑动配合时，非金属导板1的导板槽11底部会被传动片2底部的摩擦部21摩擦损耗，进而使得非金属导板1的导板槽11底部越来越深。
在第一种工作状态持续工作到非金属导板1处的导板槽11槽底被磨损到一定程度后，传动片2下沉且带着连接片3上的支撑部31搭靠在非金属导板1表面、并与非金属导板1表面形成滑动配合后。这时便进入第二种工作状态，在第二种工作状态中，摩擦部21依旧与导板槽11底部相接触且滑动配合，同时连接片3底部的支撑部31与非金属导板1周缘表面形成滑动配合，由于传动片2的两侧均设有连接片3，两侧的连接片3上的支撑部21均与非金属导板1周缘表面形成滑动配合，因此第二工作状态下，会形成三方受力的局面，由三方共同分担锯链和非金属导板1之间的力，这样便将力由三方去分别承担，也进一步的减少了传动片2底部的摩擦部21和导板槽11底部之间的滑动摩擦力。使得传动片2与导板槽11之间可以使用的更加长久，通过上述两种工作状态得以实现延长链锯总成在使用寿命。
为了避免在第二种工作状态中由于传动片2底部的摩擦部21和导板槽11槽底之间摩擦的过快而出现只有连接片3底部的支撑部31与非金属导板1周缘表面相接触，而摩擦部21和导板槽11槽底表面不接触的情况。在连接片3的上设有刮片31，该刮片31的设置是为了能够快速刮除非金属导板1周缘表面，使得传动片2底部的摩擦部21能够下沉与导板槽11槽底持续保持摩擦滑动配合。连接片3的具体结构为连接片3按中心完全对称形式的结构布置，左右上下一致，其中下边各设有一个凹弧，既支撑部31上设有凹弧。刮片31设置在凹弧的弧面上。其中在锯链上，至少一个连接片3上的支撑部31处设有刮片31。因此连接片3包括了两种结构，一种是带有刮片31的连接片3，另一种是不带刮片31的连接片3。
在实际生产安装中，导板槽11的深度可以为3.16mm，连接片3底部的支撑部31和非金属导板1表面之间的间隙6为可以为0.51mm，传动片2底部的摩擦部21的两端的倒角半径可以为R1.00mm。
为了在锯链总成实际工作中，为了控制刀片4每次切割的深度，在传动片2顶端设有向上凸起的限位块22，该限位块22高度低于刀片4高度。具体的在垂直高度上限位块22的最高点低于 刀片4切割的刀刃高度。需要说明的传动片2包括可以有两种结构，第一种传动片2没有上述的限位块22，第二种传动片2带有上述的限位块22，安装成锯链时也有两种方案，第一种锯链上的全部都采用带有限位块22的传动片2去设置。也可以是第二种在同一连接片3相连接的任一传动片2顶端设有向上凸起的限位块22。即同一个连接片3连接的两个传动片2其中一个采用带有限位块22的传动片2，另一种不带限位块22。由于在传动片2上开设向上凸起的限位块22，第一要增加生产工序，第二也提高了生产难度，第三提高制造成本，本方案中同一个连接片3连接的两个传动片2中的其中一个上带有限位块22，这样可以减少制造成本，不需要再每一个传动片2上都设置一个向上凸起的限位块22。生产制作时只需要对半生产带有限位块的传动片2即可。
需要说明的是，实际安装中，两个传动片2之间通过连接片3连接、且在传动片2的两侧均有连接片3相连接，同时传动片2和连接片3之间通过链轴连接，其中刀片4包括了左刀片4和右刀片4，左刀片4和右刀片4交替布置在传动片2的两侧，需要说明的是左刀片4和右刀片4并不是连续布置的，左刀片4和右刀片4之间至少相隔一个连接片3进行交替布置，实际安装时在传动片2的连接部设有链轴孔5，传动片2和连接片3之间、及传动片2和刀片4之间均通过链轴进行连接。
实施例二：
本实施例与实施例一的区别在于：其中为了在实际生产安装中，导板槽11的深度可以为3.16mm，连接片3底部的支撑部31和非金属导板1表面之间的间隙6为可以为0.1mm，传动片2底部的摩擦部21的两端的倒角半径可以为R0.1mm。
实施例三：
本实施例与实施例一的区别在于：其中为了在实际生产安装中，导板槽11的深度可以为3.16mm，连接片3底部的支撑部31和非金属导板1表面之间的间隙6为可以为1mm，传动片2底部的摩擦部21的两端的倒角半径可以为R10mm。
