Crisscross package assembly of universal coupler

Abstract

The invention discloses a crisscross package assembly of a universal coupler, which comprises a crisscross shaft; four shaft heads are arranged on the crisscross shaft; an oil storage hole is arranged in each shaft head, and a bearing outer ring is sleeved on each shaft head; the diameter of the inner hole of the outer end surface of the bearing outer ring is more than that of the oil storage hole; an adjusting nut is connected onto the inner hole of the outer end surface of the bearing outer ring through a thread; the outer end surface of the bearing outer ring is connected with an end cover which limits the adjusting nut; and when the crisscross package assembly is applied to the coupler, the concentricity of a middle shaft on the coupler and fork heads on both ends is adjusted through the adjusting nut. According to the crisscross package assembly of the universal coupler, the processing, assembly and other errors of the coupler can be effectively, precisely and reliably adjusted, the concentricity of the middle shaft on the coupler and the fork heads on both ends is improved, so that the dynamic balance precision of the coupler in use is improved; and meanwhile, great convenience is provided for the replacement and the maintenance of the parts of the crisscross package assembly.

Description

technical field [0001] The invention relates to a cross pack assembly on a transmission mechanism, in particular to a cross pack assembly for a SWC universal joint. Background technique [0002] The cross pack assembly is usually used in conjunction with the coupling, which mainly bears torque such as torsion. see figure 1 : The structure of the traditional universal coupling cross package assembly is, including the cross shaft 01, the cross shaft 01 has four shaft heads 02, each shaft head 02 is provided with an oil storage hole, and each shaft head 02 has The bearing outer ring 03 is set by the cylindrical roller 04, the guide ring and the dust-proof ring (the guide ring and the dust-proof ring are set at the journal), and the bearing outer ring 03 forms an interference connection with the fork hole on the coupling. The inner hole of the outer end surface of the bearing outer ring 03 corresponds to the oil storage hole on the shaft head 02. A screw plug 08 is connected t...

AI Technical Summary

Problems solved by technology

When it is applied to the shaft coupling, due to its own structural limitations, it is impossible to adjust the errors such as processing and assembly of the coupling on site. In order to highlight, the concentricity between the intermediate shaft of the coupling and the forks at both ends is low, which seriously affects the dynamic balance accuracy of the coupling during use; in addition, after the parts that make up the cross pack assembly are damaged, Inability to carry out convenient and timely replacement and maintenance
