For many years, Zhengzhou Machinery Research Institute has carried out many fruitful work in the industrial application of deep nitriding of gears. The gears have a modulus of 2.5 to 10 mm, an accuracy of 5 to 7 and a high line speed of 118 m/s. The shape has straight teeth, helical teeth, double arcs, spiral bevel teeth, inner ring gears, non-circular gears and worms. The following are two practical applications of deep nitriding, as shown in Figures 9 and 10, respectively. Example 1: Zhenhai Petrochemical Plant has an annual output of 2.5 million tons of main fan high-speed double arc gear, gear module 4.5mm, line speed 118m / s, load factor 1.63kN / m 2 , material 34Cr Ni3Mo, surface hardness 620 ~ 650HV, The effective hardened layer has a depth of 0.8 mm and a brittleness level of 1. Example 2: Baosteel Coking Plant main winch reducer input shaft gear, gear module 9mm, precision 7 grade, material 25Cr2MoV, surface hardness 730 ~ 760HV, effective hardened layer depth 0.85mm, brittle 1 level. 
Although the deep nitriding process has been applied to the gear to a certain extent, there are still many problems to be solved. In addition to the influence of the traditional concept, the cooperation of hot and cold processing is required. Due to the improvement of the hardness of the matrix, The tooth making process and the knife have new requirements; the process of grinding the teeth is omitted, and the deformation should be minimized, not only in the process of nitriding process, but also in the previous process, such as before the finishing process. Stress tempering and other measures. In order to master and apply the deep nitriding process more skillfully, it is recommended to work hard from the following points:
(1) Selection of raw materials At present, domestically available steel materials are limited, and some steel types are not easy to purchase. It is necessary to develop some special steel materials for gear nitriding, such as precipitation hardening steel, which can further improve the hardness of the matrix during nitriding. .
(2) Process research Further increase the seepage speed, increase the depth, reduce the deformation, and explore new processes.
(3) Data accumulation Explore the relationship between tissue and fatigue performance, accumulate the mechanical performance data of nitriding gears, and constantly improve relevant standards.
(4) Equipment development Establish an expert intelligent system for gear nitriding, improve the control level of equipment, and solve the problem of low automation under mass production.
The clever design sports high peel strength and substrate rigidity, paired with low shrinkage and excellent creep consistency, resulting in reliable repeatability and minimal hysteresis. A special cover layer enhances sealing, safeguarding the sensor's performance and making it well-suited for sensitive applications requiring stability, such as C3 level precision tasks.
Calibration is a breeze, as heat treatment allows fine-tuning of the temperature characteristic sensitivity coefficient. This adaptability makes our material perfect for non-external compensation sensors operating with a tight tolerance range of 0.03% to 0.05%.
By streamlining these two versatile materials' properties, we've developed a product that doesn't just meet but exceeds the demanding requirements for precision sensor systems. Choose our laminate for an uncompromised, stable, and protected sensing experience.
