硬齿面减速机与普通减速机的区别

硬齿面减速机与普通减速机相比较主要优势有传动效率高、承载能力强,配比灵活、组合方便,安装简易、成本合理,可实现模块化设计。此系列减速机采用特种钢材,经特殊处理工艺使齿轮表面硬度达到45HRC以上。不同的工艺方法获得的硬化层性能存在很大差异,下面我们就简单介绍下各种工艺的的不同特点。

Toothedsurfacereducer compared with ordinary reducer main advantages of high transmission efficiency, strong bearing capacity, the ratio of flexible and convenient combination, simple installation, reasonable cost, can realize the modular design. This series reducer using special steel, special treatment process to make the gear surface hardness of 45HRC or more. There are great differences in the properties of hardened layer obtained by different methods. The following is a brief introduction to the different characteristics of various processes.

1、减速机齿轮表面渗氮或氮碳共渗。此种工艺减速机齿轮硬化层深度较浅(一般为0.5mm),其硬度为550HV(52HRC)。其承载能力受到限制,而且氮化硬化层局部过载能力较小,氮化工艺成本很高,故较少采用。氮化减速机齿轮因不能淬火,故变形很小,一般用在不能采用磨齿工艺的内减速机齿轮和花键齿圈上。

1, gear reducer surface nitriding or nitrocarburizing. The depth of hardening layer of reducer gear is shallow (0.5mm), and its hardness is 550HV (52HRC). The load carrying capacity is limited, and the nitriding hardening layer has less local overload capacity and the nitriding process cost is very high. Because of the quenching speed of the reducer gear, the deformation is very small, and it is generally used in the inner reducer gear and the spline gear ring which can not be used in the grinding process.

2、采用中频或高频感应淬火和火焰淬火的硬齿面的减速机齿轮因硬化层与非硬化层芯部有明显的界面,硬度梯度大,同时表面硬度低(55HRC左右)。齿根淬硬困难性能和承载能力均不理想。

2, the gear reducer gear surface intermediate and high frequency induction quenching and flame quenching due to the core of the hardened layer and non hardened layer have obvious interface, hardness gradient, and the surface hardness is low (about 55HRC). The root of hardened difficult performance and bearing capacity are not ideal.

3、减速机齿轮表面渗碳后再淬火。此种工艺加工的减速机齿轮表面硬度高(58HRC~62HRC),齿面硬化层均匀,从表面往里的硬度只有微不足道的下降(由残余奥氏体决定)。从硬化层往心部的硬度梯度小,具有最佳的抗硬化层剥落能力。因此,渗碳硬化层承载能力高,得到了广泛的应用。

3, reducer gear surface after carburizing quenching. The surface of the reducer gear machined by this technology is of high hardness (58HRC ~ 62HRC), and the hardened surface of the tooth surface is even, and the hardness of the surface is only a slight drop from the surface. The hardness gradient from the hardened layer to the core is small, and it has the best ability to resist spalling. Therefore, the carburized hardened layer has high bearing capacity, which has been widely used.

无论是硬齿面减速机还是二次包络蜗轮副,先进合理的设计、高精度的制造、组装、全面的性能检测保证外,正确的装配才是保证齿轮箱长寿命、安全可靠工作的重要环节

Whether toothedsurfacereducer or two enveloping worm gear pair, ensure reasonable design, advanced manufacturing, high precision assembly, comprehensive performance test, the correct assembly is an important link to ensure the gear box, safe and reliable work and long service life
