The development of the domestic paver's weight wheel is a long way to go
In fact, the working people of our country are very intelligent and have become a world power many times in the ancient history.
Today, for the construction machinery industry, China is big and not strong, that is to say, there are many large enterprises, many small businesses, and the market is developing widely in the world, and its reputation is also very loud. It doesn't mean that compared with foreign high-end construction machinery enterprises, China's products are not as accurate as they are, but their quality, performance and environmental protection have not reached the best level. Conservatively speaking, the sales advantages of China's construction machinery products in the domestic and foreign markets are: low price and capable of basic demand. We are doing this to develop the market.
Just take the Paver accessories - a heavy wheel.
The support wheel is fixed under the wheel frame with screws to support the quality of the machinery and to distribute the quality on the crawler plate. At the same time also rely on the wheel flange clamp of caterpillar track lateral slip (the derailment), which has the rolling resistance and the mud and water work with smaller the life span of mechanical movement along the track direction ".
In this sense, the supporting wheels need not only support heavy weight but also play a fixed role. Therefore, the high quality heavy wheel can certainly do all two aspects. What are the improvements for the supporting wheels produced by domestic manufacturers?
1, material and technological problems. A lot of steel marks have not reached the standard, and the heat treatment process is not very good. Some manufacturers use steel material is not good enough, or the material is good, the processing technology has not reached the advanced standard, so the products can not be called high quality products.
2, the market is vicious competition. Several important structures of products are Jerry built, such as wheel diameter decreasing, branch shaft fining and copper sleeve length shortening. This is because the manufacturers are short-sighted, only seeing immediate interests, or under market pressure.
The decrease of the round diameter of the wheel turns to the speed of the wheel line, and the more friction the bushing bears.
It is the same for the shaft to be thinned, and the strength of the impact will not be enough, and the axis is deformed or broken.
The copper sleeve plays a role of friction. The copper layer must not be easy to fall off after rolling. After reaching normal 0.35mm level, the copper layer will reach the standard, and the significance of reducing the length of the copper sleeve length support wheel will also lose its function. Reducing the length is equivalent to reducing the stress area.
Before, ZOOMLION put forward a point of view "craftsman spirit". It refers to the craftsman's spirit of refinement and refinement of his own products. If each manufacturer of the production engineering machinery parts is the purpose of the enterprise development, then how do you worry about the quality of the accessories?
The construction machinery home (http://www.700618.com/), adhering to the idea of "striving for perfection", specializes in building the best construction machinery parts for users. Our products are satisfied with your products.
