Tires are an important part of the scraper, because the construction environment of the scraper is harsh, the tires have more stringent requirements.
Each kind of scraper has specified the specifications, types, levels, patterns and inner tubes of its tires. When choosing tires, it is necessary to choose tires with some
outstanding performance according to the specific conditions of the working environment, and comprehensively consider various influencing factors such as road conditions,
climate, load, speed and working conditions. At the same time, some characteristics of the tire are mutually restricted, must be considered comprehensively,
can not ignore one or the other. The following points to pay attention to purchase:
When choosing a tire, it should also consider its walking quality, traction, off-road ability and the service life of the outer tire surface. The oblique cord tire has a very thick
side wall, and its puncture resistance and lateral stability are good. It is usually used under the conditions of large impact load and strong corrosion, but this kind of tire has
a fast heat and is not suitable for long-distance high-speed operation. Radial tire heat is small, the temperature rise of the tire is relatively low when running at high speed
or long distance, and its elasticity is good, and the rolling resistance is small, the scraper should choose this kind of tire when working in the milk soil.
The characteristics of the scraper tire, such as high load, large traction and harsh use conditions, require a large ground area of the tire, so that the tire has a low ground
pressure, the tread is resistant to wear and puncture, and the heat generated in each part is small. The wide section of the tire, the high camber of the driving surface,
the position of the horizontal axis of the section, the shoulder arc, the thickness of the tread and the Angle of the crown cord will affect these properties,
and then affect the service life of the tire.
The same scraper should choose the same type of tires, especially the tires used on the same shaft must be the same specification, type and level.
Because the number of tire specifications is not the same as the nominal size and the actual size, the actual size of the tire with the same nominal size may be different,
which can lead to different rolling radius; The specifications of the tire and the wheel must be matched. If the wheel width is too small, the curvature of the tire tread
will be large, which will aggravate the wear of the tire. If the wheel width is too large, the tread will land on the shoulders and the center will be concave, which will lead to serious uneven wear.
