The Development History of Mining Machinery

2020-03-17

The status of mining machinery is becoming more fundamental: developed countries emphasize the development of the mining machinery manufacturing industry, which not only occupies a leading position in terms of its share, accumulation, employment, and contribution to the national industry, but also provides an important material foundation for the development and production of new technologies and products in the equipment manufacturing industry, making it an indispensable strategic industry for a modern economy. 2. The trend of cross-border mergers and acquisitions in the mining machinery manufacturing industry is intensifying: 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. 3. The structural adjustment of mining machinery is further deepening, with rapid changes occurring in production methods and management models.

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.

1) Forge the shaft; (2) Drill screw holes at both ends of the shaft using a drilling machine; (3) Rough turning; (4) Normalizing treatment; (5) Finish turning; (6) Medium temperature stress relief; (7) Perform the first external grinding on the outer circle of the shaft; (8) Process the left-hand and right-hand gears on the shaft; (9) Carburizing and quenching; (10) Perform the second external grinding on the outer circle of the shaft; (11) Gear grinding; (12) Use a symmetry detection device to check the symmetry of the left-hand and right-hand gears; (13) Adjust symmetry to ensure symmetry ≤ 0.03m.

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.

How to properly protect yourself during the pandemic

1. Wash hands frequently, using running water and hand soap; 2. Clean the surface of seats daily and disinfect regularly; 3. Ensure proper indoor ventilation, but be cautious of colds caused by large temperature differences between indoors and outdoors; 4. If the skin is contaminated, immediately remove the contaminants and disinfect with 0.5% iodine tincture or chlorine disinfectant; 5. If mucous membranes are contaminated, rinse with a large amount of saline or disinfect with 0.05% iodine tincture; 6. If clothing is contaminated, it can be disinfected with steam or by boiling for 30 minutes.

Gear processing technology

2020-02-12

The processing technology of gears includes the following processes: gear blank processing, tooth surface processing, heat treatment process, and finishing of the tooth surface. 1. The gear blanks are mainly forged parts, bars, or castings, with forged parts being the most commonly used. The blanks are first subjected to normalizing treatment to improve their machinability, making cutting easier; then rough machining is performed according to the gear design requirements, shaping the blank into a rough form while leaving a significant amount of excess material. 2. Next, semi-finishing is carried out, including turning, rolling, and tooth insertion, to basically form the gear; after that, the gear undergoes heat treatment to improve its mechanical properties. Depending on the usage requirements and the materials used, this may include quenching and carburizing.

The origin of the name "spiral bevel gear".

2020-01-20

"Spiral bevel gears have specific characteristics: space-saving, wear-resistant, long lifespan, and low noise. Spiral bevel gears, also known as spiral conical gears, are commonly used for motion and power transmission between two intersecting shafts. The teeth of the conical gear are distributed on the surface of a cone, with the tooth shape gradually decreasing from the large end to the small end. The tooth shape of spiral bevel gears is arc-shaped, and they are generally conical, resembling an umbrella, hence the name spiral bevel gear."

The development trends of the gear industry.

2020-01-13

According to the "China Gear Industry Production and Sales Demand Forecast and Transformation Upgrade Analysis Report", the gear transmission industry in China experienced rapid development during the "11th Five-Year Plan" period. From 2005 to 2010, the total industrial output value of the Chinese gear industry increased year by year, with a year-on-year growth rate of over 20%. In 2010, the total industrial output value of the entire gear industry reached 94.635 billion yuan, and the market demand for gears exceeded 140 billion yuan, ranking second in the world. In terms of scale, sales, and other factors, the gear industry has become a "leading" industry in the field of general mechanical components in China. China has become a veritable world power in gear manufacturing. By the end of 2011, there were 2,319 manufacturing enterprises in China for bearings, gears, transmission, and drive components, with a total industry asset of 248.316 billion yuan, a year-on-year increase of 20.59%. In 2011, the manufacturing enterprises above designated size for bearings, gears, transmission, and drive components achieved main business income of 314.4 billion yuan, a year-on-year increase of 28.00%; and realized a total profit of 23.04 billion yuan, a year-on-year increase of 22.08%.
