Crushed stone machinery exported to Russia in the first quarter increased significantly

For the rapidly growing domestic industry of gravel machinery, the domestic market is far from meeting the needs of enterprise development. Internationalization has become the only way for the development of many gravel machinery enterprises. In addition, the domestic market for gravel machinery exports Also began to rise rapidly. It is reported that in the first quarter of 2011, the Heihe port exported 517 sets of shovel-type transportation, crushed stone and sand-making crushed stone machinery to Russia, with a total value of 21,433,700 USD, up 237.91% and 149.03% respectively. The gravel machinery has become the leading commodity of Heihe port export machinery and equipment. Judging from the type of exports, the jaw crusher accounted for the largest share, accounting for more than half, followed by the cone crusher machine and counterattack crusher, the products are mainly Liming Heavy Industry and other famous crusher brands.

The data shows that since 2000, Russia has become the fastest growing country in the construction field in the world, and the construction market has increased by 10% to 15% every year. Since 2011, the Russian economy has rapidly recovered and the market demand for gravel machinery continues to increase. Under the influence of rising real estate prices in Russia, the influx of investment has stimulated the vigorous development of the construction industry, which has brought tremendous business opportunities to the growth of the Russian gravel machinery and construction machinery market. At the same time, the depreciation rate of Russian construction and crushed stone machinery has reached 45% to 75%, and it is difficult for local companies to raise funds to cause lagging technology and management, thus failing to meet market demand for equipment. At present, 50% of the machinery and equipment in use in the country originate from imports, accounting for 30% of the total imports. With the maturity of Chinese gravel machinery products, many well-known brands have also won widespread recognition from Russian customers with higher prices. Dawning Heavy Industry Technology has been working closely with the Russian industry for several years.

Analysts said that there are three main reasons why the Heihe Port’s sharp increase in the export of gravel machinery to Russia. First, the market demand for gravel machinery and construction machinery in Russia is booming. The Russian construction industry is currently booming. With the continuous rise of international crude oil prices, Russia’s economy is rapidly recovering, and oil and gas and mineral development are in great demand for gravel machinery. The rapid development of the industry, and Russia's local gravel mechanical products can not meet the needs of the domestic market, which has created a huge opportunity for Chinese gravel machinery enterprises to export to Russia. Second, Chinese gravel machinery products are cost-effective. In recent years, China's gravel machinery manufacturing industry has risen rapidly and its products are of high quality and low cost, and are highly favored by Russian users. The third is the unique geographical advantage of Heihe Port. Heihe port is close to the corresponding port of Blagoveshchensk in Russia and has a high specification. Compared with other ports, it has obvious advantages in product export transportation, customs declaration in Russia, and logistics sales. In particular, in terms of export transportation, there is no need for transport equipment to be loaded out of the country during the freezing period. Instead, it is exported through the self-drive way.

Robot Bearing

Industrial robot bearings mainly include thin-walled bearings, cross cylindrical roller bearings, harmonic reducer bearings and joint bearings, but mainly cross roller bearings. Structural features of cross roller bearings in welded robot joints: cylindrical rollers are perpendicular to each other in the inner and outer raceway of the bearing, and a single bearing can bear the common load of radial force, bidirectional axial force and overturning moment simultaneously. The bearing has large bearing capacity, good rigidity, high rotation accuracy, easy installation, saving space, reducing weight, significantly reducing friction and providing good rotation accuracy. It is possible to make the mainframe light and miniaturized.

With the rapid development of China's industrialization, industrial robots are becoming more and more popular in industrial applications. The main part of the industrial robot, bearing, is being paid more and more attention.
The main structure is as follows: the whole type, the outer ring separation type and the inner ring separation type. In order to prevent pollution and leakage, sealing rings are installed on both sides of the bearing. Because of its unique lightweight structure and good performance, cross roller bearings can simplify design and save space, and are widely applied in robot joints and rotary units, precision turntables, aerospace and other fields. In order to make serial production of industrial robots cross rolling bearings, the technical standard of cross roller bearings is formulated, which has the leading technical advantage in line with international standards.

Cross roller bearings are two row cylindrical rollers on 90 degree V raceway, which are vertically arranged across each other through nylon isolation blocks. Therefore, cross roller bearings can withstand multiple loads such as radial load, axial load and torque load.
The bearing has unique structure, good performance, simplified design and save installation space. It has been widely applied in welding robot joint and rotary unit, precision turntable and other fields.
