The story of "Hercules"

Archimedes said: give me a pivot, I will pry the earth. And the heavy wheel said: give me a chance, I can take up the whole paver.

The story of the big Hercules

So what is the effect of a heavy wheel?

The support wheel is mainly used for fixing the screws under the wheel frame 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 ".

Supporting wheels to support heavy machine gravity, it is rolling on the track link or track guide board. Therefore, it is used to clamp the track to prevent the crawler from derailment. And drive the track to slide at the upper side of the ground. The support wheels sometimes work in the mud water and bear a large impact load. Therefore, the requirements of the seal are reliable, the flange wear and the rolling resistance are small.

The story of "Hercules"

Therefore, because the supporting wheels need not only to bear the same weight, but also to withstand the test of all kinds of harsh environments, the quality requirements of the supporting wheels are quite high.

The construction machinery home adopts the precision forging process instead of the ordinary forging process to improve the accuracy of the forging wheel blank, reduce the subsequent machine working hours, improve the comprehensive utilization and market competitiveness of the materials, so as to achieve the goal of reducing the cost and increasing efficiency.

The roller material is 40Mn2, is a kind of carbon steel, the shape characteristics of the parts is: and there are deep hole and flange hub height, shape diameter gap, thin wall metal flow is more difficult. According to the characteristics of the existing equipment, the open type precision hot die forging is adopted to reduce the deformation resistance. According to the structural shape and precision forging process characteristics of the supporting wheel, the outer surface of the wheel body is determined to be directly forged instead of machining allowance, leaving only a little machining allowance in the hole part, so that the material utilization and production efficiency have been significantly improved.

The combined insert type precision forging die structure solves the problems of existing lifts, such as low service life and difficult retreading, which improves the production efficiency of dies and reduces the cost of making moulds.

In a word, the production efficiency and quality of the support wheel provided by the engineering machinery house are high and stable, in which the large support wheel of the RP902 paver is the most popular choice for the customers.
