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.

How to properly protect against viruses when going out

2020-02-16

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

2020-02-12

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%.
