The analysis of the loading force of the home-made and introduced saw chain shows that the designed parameters of the cutting teeth components of the existing universal saw are not completely reasonable. LF serulfs in concenfration of the resulfant of normal pressure, causes leaning wear of links,and shortens the working life of chain. Meanwhile, the function of the worn cutting teeth component is considerably reduced, which affects the mechanical properties of chain saw. In order to reducl there...

The analysis of the loading force of the home-made and introduced saw chain shows that the designed parameters of the cutting teeth components of the existing universal saw are not completely reasonable. LF serulfs in concenfration of the resulfant of normal pressure, causes leaning wear of links,and shortens the working life of chain. Meanwhile, the function of the worn cutting teeth component is considerably reduced, which affects the mechanical properties of chain saw. In order to reducl there problems, the cuffing teeth component is redesigned in order that the resulfant of normal pressure is distributed uniformly on many points, it is demonstrated through pooduction and tests on the test platform that the working life of the new chain is as about two times as that of the Romemade ones and 1.5 times as that of STIHL in West Germany, its cutting efficiency is 35—116.7 percent higher than that of home-made chain and 3—5 percent than that of OREGON. At the same time, the cutting teeth component is always in a good cutting state and keeps main parameters of the original derignation in the whole production. It is proved that the desiging theory"resultant of normal pressure is distributed uniformly on mang points"is a reliable way to overcome leaning wear of links.

通过对国内外万能锯链负荷工作时的受力分析,发现现有万能锯链的切齿组件的设计几何参数不尽合理。因而,造成正压合力集中,促使连接片偏磨,缩短了锯链寿命。同时,偏磨后的切齿组件切削功能恶化,影响了链锯机械性能的发挥。为此,重新设计了切齿组件,使正压合力趋向多点均匀分布。经生产、台架试验证明,新型锯链的使用寿命,是国产锯链的2倍左右,是斯蒂尔锯链的1.5倍;切削效率比国产锯链提高35—116.7%,比奥利根锯链提高3—4%。同时,切齿组件在整个生产过程中,始终保持着良好的切削状态和原设计的主要几何参数。证明“正压合力多点均匀分布”的设计理论是克服连接片偏磨的可靠途径。

The effects of high frequency induction braze welding technique on the microstructure of the band saw blade, which is used for universal saw-machine, have been investigated. On the basis of the above investigation, a ratiorial technique of the induction braze is proposed in the paper. Experiment results show that the tensile strength, elongation and bend property are 2.6, 1.9, 3.6 times respectively as much as that of the butt welding joins. By the saw-machine running test, it shows that the life...

The effects of high frequency induction braze welding technique on the microstructure of the band saw blade, which is used for universal saw-machine, have been investigated. On the basis of the above investigation, a ratiorial technique of the induction braze is proposed in the paper. Experiment results show that the tensile strength, elongation and bend property are 2.6, 1.9, 3.6 times respectively as much as that of the butt welding joins. By the saw-machine running test, it shows that the life of old blade welded by the proposed technique can be compared with the original one.

通过对万能工具锯床带锯条高频感应钎焊工艺及其对带锯条组织影响的研究,确定了带锯条高频钎焊的合理工艺。实验结果表明,高频感应钎焊锯条焊口的抗拉强度、延伸率和弯曲性能分别为对接熔焊锯条的2.6倍、1.9倍和3.6倍。装机试验证明,高频感应钎焊旧锯条的寿命可赶上原锯条寿命。

In this paper several important theoretical problems in dialectical philosophy were discussed, and some original views were put forward. The author thinks that:Unity of opposites is a relation category and one divides into two is a practical indication structure category. These two are not discussed in the same gradation and yardstick. It is the root of extreme contradictory dialectics; The law of the coordination of differences develops the interrelated theory of dialectical philosophy. The mutual distinction and interrelation of the two laws are mainly embodied in the mutual distinction and interrelation of the two categories of difference and opposite; In dialectical philosophy one ,two ,three and many are of the meanings in four yardsticks of relation,function,structure and development analysis. It is not suitable to exclude the meanings in other yardsticks with the meaning in one yardstick,or take out disorderly from the meanings of multi-yardstick a few different aspects and put them together;Because the development is an orderly evolutionary course of time and space structure appeared in the movement of things .development study and structure study of things can not be cut a-part; Development is also an evolutionary branch reflected in the lengthwise relation of things. The former views about things eternal development were not proved by natural science in dialectical philosophy,and hardly can hold water for a universal saw. Also discussed the intermediary, the negation of negation and so on.

本文对辩证哲学中的诸多重大理论问题进行了讨论,并提出了一些独到见解.本文认为:对立统一是关系范畴,“一分为二”是实指性结构范畴,二者并不是在同一个层次和尺度上讨论问题的,将二者直接划等号是极端化的矛盾辩证法产生的根源;差异协同律是对辩证哲学相关理论的一个发展,它与对立统一律的区别与联系主要体现在差异与对立这两个范畴的区别与联系上;辩证哲学的一、二、三、多具有关系、功能、结构、发展分析四重尺度的含义,用其中任一尺度的含义排斥其它尺度的含义,或在多重尺度的含义中杂乱抽取出几个个别方面拼凑在一起的作法都是不合适的;对于事物的发展研究和结构研究是不能割裂的,因为发展乃是事物在运动变化中呈现出来的时间(时空)的有序化进化过程;发展还是事物纵向联系中所体现出来的进化演化的分支,以往辨证哲学中关于事物永恒发展的观点并未被现代自然科学所证明,它作为一个普遍适用的规律是很难成立的.文章还对中介、否定之否定等方面的问题进行了讨论.
