What are the processes for gear machining in Shenyang?

1. Casting and forging still remain widely used blank casting processes for automotive gear components. In recent years, wedge rolling technology has been extensively promoted in the processing of shaft components. This technology is particularly suitable for producing complex stepped shafts, as it not only offers high precision and small machining allowances but also has high production efficiency. 2. Normalizing The purpose of this process is to achieve a hardness suitable for subsequent gear cutting processing and to prepare the structure for final heat treatment, effectively reducing thermal deformation during heat treatment. The gear steel material used is generally 20CrMnTi. Normalizing is significantly affected by personnel, equipment, and environmental factors, making it difficult to control the cooling rate and uniformity of the workpiece, resulting in large hardness variations and uneven metallographic structures, which directly affect metal cutting processing and final heat treatment, leading to significant and irregular thermal deformation, making it difficult to control the quality of the parts. Therefore, isothermal normalizing technology is adopted. Practical experience has shown that isothermal normalizing effectively addresses the shortcomings of conventional normalizing, resulting in stable and reliable product quality. The basic requirement for cage design is to meet the maximum load capacity and rotational precision and speed of the bearing within a certain space and structural strength. The guiding method for the inner and outer diameters or rolling elements can be determined based on the operating conditions of the bearing in the main machine and the requirements for guiding clearance, thus confirming the structure and main parameters. When rolling bearings operate, heat and wear are generated due to sliding friction, especially under high-speed conditions. The effects of centrifugal force and inertial force accelerate the collision and friction wear and heating of the rolling elements, inner and outer rings, and cage. In severe cases, this can lead to cage burning and cracking, causing the bearing to fail to operate normally. Cage damage accounts for a significant proportion of bearing failure modes, and the quality of the cage material is one of the main reasons for cage damage. Therefore, the material for bearing cages is required to have excellent mechanical strength, dimensional stability, and outstanding plasticity and machinability, among other functions.

The function of gears.

2020-04-18

Gears are toothed mechanical components that can mesh with each other, and their application in mechanical transmission and the entire mechanical field is extremely widespread. Modern gear technology has reached: gear module from 0.004 to 100 millimeters; gear diameter from 1 millimeter to 150 meters; power transmission can reach over 100,000 kilowatts; rotational speed can reach hundreds of thousands of revolutions per minute; and the highest circumferential speed can reach 300 meters per second. With the development of production, the smooth operation of gears has received attention. In 1674, Danish astronomer Romer first proposed using an epicycloid as the tooth profile curve to achieve smooth-running gears.

The origin of the bevel gear.

2020-04-10

Bevel gears, also known as conical gears, are used for transmission between intersecting shafts. Compared to cylindrical gears, they can change the direction of transmission. The single-stage transmission ratio can reach up to 6, with a maximum of 8. 1. Straight and helical bevel gears are relatively simple to design, manufacture, and install, but they produce more noise and are used for low-speed transmission (<5 m/s); straight bevel gears can transmit power up to 370 kilowatts at a circumferential speed of 5 meters per second. Helical bevel gears operate smoothly and have a higher load capacity, but they are more difficult to manufacture and are less commonly used. 2. Curved bevel gears feature smooth transmission, low noise, and high load capacity, making them suitable for high-speed heavy-load applications.

What are the development trends of mining machinery?

2020-04-03

1. The status of mining machinery is foundational: Developed countries place great importance on the development of the mining machinery manufacturing industry. Not only does it account for a significant share in their national industries, but it also leads in accumulation, employment, and contribution. Moreover, the equipment manufacturing industry provides an important material foundation for the development and production of new technologies and products, making it an indispensable strategic industry for a modern economy. Even industrialized countries that have entered the "information society" highly value the development of the machinery manufacturing industry. 2. Intensification of multinational mergers and acquisitions in the mining machinery manufacturing industry: Modern mergers and acquisitions in mining machinery no longer solely emphasize competition. Instead, forming strong alliances to establish mining machinery enterprises has become a primary means of gaining competitive advantages.

The Development of Gears

2020-03-04

The transmission of gears was already evident over three hundred years before Christ. The ancient Greek philosopher Aristotle had already elaborated on this issue. The operation of bronze or cast iron gears was involved in the transmission of motion. In ancient China, a complete theoretical system had already been applied in the design of the south-pointing chariot. However, ancient gears were made of wood or metal and did not possess the special characteristics of modern Hebei gears. Yet, through hundreds of years of development, Hebei gears have become a remarkable product of innovation. When gears operate normally, they have a significant impact on the precision of torque. This is mainly due to the primary components made of cast iron.

How to properly protect against viruses when going out

1. If your home is not on a high floor, it is recommended to take the stairs instead of the elevator. This is because elevator shafts are enclosed high-risk spaces, especially in business elevators with high foot traffic. 2. When waiting for the elevator, do not stand too close to the hall door. The first person to enter the elevator should stand at the back to avoid close face-to-face contact with new passengers. Keep as much distance as possible between individuals. 3. When riding the elevator, regardless of whether you are alone or not, you should wear a mask at all times. 4. When pressing the elevator buttons, you can wrap your hand with a tissue (or plastic wrap) or use a pen that you carry with you to press the buttons. 5. Try to avoid being in the elevator with multiple strangers.
