Technology Description
Our company has more than ten years of experience in the production of transmission parts. At present, we can produce and process ZA (Archimedes) worm, ZI (involute) worm, ZK (cone envelope) worm, plane double envelope worm, double lead worm and matching worm wheel and hob. In addition to the worm gear pair, it can also process various gears, face teeth, splines, internal threads, various non-standard products, special-shaped parts, etc.
Now for regular products to simple instructions:
General description:
The transmission ratio is large. Compared with the transmission ratio of gear worm transmission, the transmission ratio of gear transmission is usually between 10:1 and 60:1, while the transmission ratio of gear transmission is generally between 3:1 and 5:1. This makes the worm drive suitable for the transmission of large torque and low speed occasions, while the gear drive is suitable for small and medium torque and high speed occasions.
The transmission is stable. The worm teeth of the worm drive are continuous and uninterrupted spiral teeth, which are continuously meshed with the worm gear teeth, so the work is stable, and the impact, vibration and noise are relatively small.
1. Archimedes is the most common worm tooth shape. Compared with other worm tooth shapes, it has the advantages of simple structure, low processing difficulty, low noise, and easy installation.
2. The second enveloping worm is generally produced by special machine tools and matched with corresponding hobs. The bearing capacity is 3-5 times that of other straight profile worms of the same specification (depending on the actual number of enveloping teeth). It has the advantages of high conversion rate and long service life, and has self-locking function. The disadvantage is that due to the increase in the number of contact teeth, the noise and temperature will increase accordingly, and the actual use environment should be considered in the design.
3. Double-lead worm, close to ordinary ZA worm, tooth thickness normal gradient, can control the gap during assembly, improve transmission accuracy, adjust the position of the worm during use, compensate for the wear gap, and maintain accuracy to a certain extent, Improve service life.
2. gear
General description:
The mechanical efficiency is high, because the worm drive is sliding friction, and the change of direction loss is large, so the gear transmission efficiency is higher.
Under the same requirements, the gear can be smaller in size and lighter in weight.
Gear reducer is generally output input to the same direction, the field space environment requirements are low.
The gear reducer is small in size, light in weight, long in service life, stable in operation and low in noise.
1. Herringbone teeth, with anti-backlash function, can be used for precision parts such as spindles.
2. Helical gears can be matched with gears or worms, and the choice space is relatively large.
3. Bevel gears, enveloping straight umbrellas and spiral umbrellas can be used for direction conversion and other occasions. General production requires supporting production.
3. end tooth
General description:
Face toothed disc is a special type of gear, which is used to transmit torque and power, and has the characteristics of ring teeth. It is mainly used in conveyor chains or gear systems assembled in rotating machinery to provide high torque and low speed power transmission.
1. Mechanical transmission system: the end gear is often used in the transmission system of various industrial machinery and equipment, such as refrigeration equipment, mixing equipment, conveying equipment, press, etc. In these equipment, the face gear can reliably transmit torque and power, so that the equipment can operate normally.
2. Automotive industry: Face gear discs are widely used in automotive transmission systems. In the transmission system, the face gear is used to transmit the power of the car engine, so that the car can shift gears smoothly and provide sufficient torque.
3. Mining and petroleum industry: In the mining and petroleum industry, face gear discs are widely used in conveying systems and drilling equipment. They can withstand high torque and heavy loads, ensuring continuous operation of the equipment.
4. Wind and hydro power generation: In wind and hydro power generation equipment, the face gear is used to transmit wind or hydro energy and generate electricity through generators. These applications require a chainring that can withstand high-speed rotation and changing torque.
5. Heavy machinery: end gear discs are also widely used in heavy machinery and equipment, such as elevators, winding machines and cranes. In these applications, the chainring needs to be able to withstand a large amount of weight and strong torque.
4. cases
During the practice, for customers to solve many processing problems, such:
1. Worm and matching gear ring required for aerodynamic experiments. The diameter of the ring gear is nearly 2 meters, the wall thickness is only 50mm, the height is 40mm, and the thinnest part is less than 20mm. The material used is 10-1 tin bronze. The material is soft and the diameter is large and only 140 of it is taken. It is very easy to deform in the processing process. Finally, through the unremitting efforts of the company's personnel, the goods are delivered smoothly.
2. The pitching structure for near-Earth satellites has the characteristics of large modulus, large weight and small backlash due to its use environment. The overall weight of close to 1 tons, due to the use of special units, only a simple description. According to the requirements of the design for the second envelope structure for production, after the successful delivery.
3. The take-off and landing structure of a weapon requires large bearing capacity, long service life, no jitter, frequent positive and negative operation, smooth and stable. After the use of secondary envelope structure, a success, and than before the structure to reduce the volume, improve the landing speed, at the same time due to the self-locking characteristics of the structure also avoid the positioning is not accurate, reverse displacement and other issues.
4. A radar reassembly structure, the old product due to the use of harsh environment, there will be jitter, shift, not durable and other phenomena, re-designed for its secondary envelope structure, successfully solved the previous problems.
5. The old product of a machine tool indexing turntable uses ordinary Archimedes structure with large reverse clearance. After that, a double-lead worm was designed and produced for it again, which solved the problem of reverse clearance without changing other accessories.
6. The internal thread structure of a university petroleum machinery has processing difficulties such as large spiral angle, long spiral line and small gap. After being studied and discussed by the company's personnel, a reasonable processing scheme is given and processed and delivered, and a special processing machine is designed according to its processing requirements.
5. multi-axis grinding machine
After more than ten years of experience, our company has not only kept improving in the production and development of transmission parts, but also independently developed and produced special grinding machines for secondary enveloping worm (which can turn and grind secondary enveloping worm and hob), multifunctional grinding machines (which can grind secondary enveloping parts (worm and hob) and straight profile structures (Archimedes worm and hob; Double lead worm, etc.)).
From the beginning of the semi-closed loop to the later full closed loop, the products are also gradually upgraded, and there will be more convenient and more comprehensive machine tools for production and sales. Products are sold throughout the country, by Beijing, Tianjin, Shandong, Jiangsu, Fujian and other places of customer recognition. It is widely used in building lifting, rotary support, metal smelting, metal forging, ship machinery, automobile industry, solar photovoltaic, robot joint, machine tool turntable and other major fields.
