Description :

　　The roller shaft support consists of a steel pipe support installed (clamped or welded) on the pipe and a roller shaft, roller or ball disc and other components set on the supporting structure to form a heating movable support. It can reduce the frictional force during pipeline expansion and contraction displacement. Roller shaft, roller type support, when the pipeline undergoes axial displacement, there is rolling friction between the pipe support and the rolling components, with a friction coefficient below 0.1; But when the pipeline is laterally displaced, there is still sliding friction between them.

　　The roller support and the horizontal movement of the pipeline in all directions are caused by rolling friction. It requires necessary maintenance to keep the rolling components in normal condition

　　The steel truss roller shaft support is mainly composed of support, drum, shaft sleeve, axle, etc. To achieve high load-bearing capacity, the rolling support can be made of alloy steel as a whole. This product does not use bearings, but instead uses a composite material made of alloy steel and graphite to make the shaft sleeve. Its advantages are: good performance, low friction coefficient, high bearing capacity, no need for regular refueling, and lifetime maintenance free.

　　Performance characteristics of steel truss roller shaft support

　　The steel truss roller shaft support is a targeted rolling support that can be designed according to user needs. It has the following advantages:

　　Maintenance free - Due to the inherent characteristics of the shaft sleeve material, no refueling is required during operation, and maintenance is not required for life;

　　High load capacity - due to surface contact, its load capacity is stronger than that of tapered small roller bearings;

　　Low friction coefficient - due to the presence of graphite in the material of the shaft sleeve, which has a self-lubricating effect, its friction coefficient is relatively small;

　　——Because its lubrication does not use lubricating oil, the higher the inherent characteristic temperature of the material, the lower its friction coefficient.

　　As a basic form of support in building structures, the ideal force transmission mode of roller steel bearings is to transfer vertical loads from the upper structure and release horizontal internal forces generated by factors such as temperature changes. The performance of rolling bearings depends on the rolling friction performance of the rollers, and there is currently relatively little research on this aspect both domestically and internationally. This article focuses on a unidirectional rolling bearing for a certain project, and tests its rolling friction performance under vertical load, lateral horizontal load, and the combined action of vertical load and lateral horizontal load. Through experimental research, the influence laws of vertical pressure on the bottom roller and lateral horizontal pressure on the rolling friction coefficient of the side roller have been mastered. At the same time, the experimental results also indicate that under the combined action of vertical and horizontal loads, the measured frictional force of the bottom roller and side roller working together is slightly greater than the combined frictional force of the bottom roller and side roller working separately. The research results provide a basis for the design of structures with this type of support form.
