Problems solved by technology
[0003] The existing compound rollers drill holes with a diameter of 40mm-50mm through the channel steel and fix them with screw structures, which leads to insufficient strength of the channel steel and complicated processing. Some composite rollers often use 0.8mm stoppers to prevent the bracket from rotating, but the effect is not good

The invention discloses a composite roller for a portal frame for a forklift. The composite roller comprises a main roller, a side roller, a shaft head and a shaft retainer ring, the main roller is connected to the side roller through the shaft head and comprises an inner ring, a rolling body, an outer ring, a sealing part and a retainer, the shaft retainer ring is arranged on the shaft head, theside roller comprises a mandrel, a side roller sleeve, a plane bearing, a support, a roller pin and a positioning pin, and the positioning pin is arranged on the support. According to the composite roller for the portal frame for the forklift, the thickness of a side roller gasket is 0.5-1.5 mm, the side roller in the composite roller is taken out, side roller gaskets with different thicknesses are replaced to adjust the side clearance between the side roller and the portal frame, a hole with the diameter of 4.2 mm is formed in channel steel, the positioning pin with the diameter of 4 mm is inserted into the hole, a positioning groove with the width of 4.2 mm is milled in one side of the support, a positioning column is arranged on one side of the shaft head, protrudes out of an inner holeof the shaft head and is embedded into the positioning groove of the support, so that the support can be effectively prevented from rotating, and therefore the service life of the composite roller isprolonged, the effect is good, a shaft head material is saved, and the shaft head is easy to machine.
Description
technical field [0001] The invention relates to the technical field of composite rollers, in particular to a composite roller for a mast for a forklift. Background technique [0002] The composite roller bearing is assembled from two axial and radial roller bearings, which reduces the volume of the bearing and simplifies the installation structure, thereby reducing the manufacturing cost. Composite roller bearings have relatively large radial and axial bearing capacity, and the parts are highly replaceable, so they are more and more used in various mast lifting systems. [0003] The existing compound rollers drill holes with a diameter of 40mm-50mm through the channel steel and fix them with screw structures, which leads to insufficient strength of the channel steel and complicated processing. Some composite rollers often use 0.8mm stoppers to prevent the bracket from rotating, but the effect is not good. Contents of the invention [0004] The purpose of the present inve...
