Abstract

The invention relates to a gear transmission device with a variable center distance. The gear transmission device comprises a rack, and is characterized in that an upper roll shaft and a lower roll shaft are arranged on the rack, wherein the upper roll shaft is arranged on the rack through an upper supporting bearing; the lower roll shaft is arranged on the rack through a lower supporting bearing; an upper pressing roll an d a lower pressing roll are assembled on the upper roll shaft and the lower roll shaft respectively; the upper roll shaft is provided with an upper gear; the lower roll shaft is provided with a lower gear; the upper gear is engaged with the lower gear; and the upper supporting bearing is provided with an adjusting mechanism capable of adjusting a vertical position of the upper supporting bearing. The adjusting mechanism comprises an adjusting rod which is connected with the upper supporting bearing; and the adjusting rod is fixed with the rack through a fastening bolt. The gear transmission device has the advantages that (1) the center distance of the gear transmission can be adjusted to meet roller forming requirements of flat steel with different thicknesses, and (2) stable and reliable gear transmission is guaranteed by applying a deflection technology when the center distance of the gears is adjusted within a certain range.

Description

technical field [0001] The invention relates to a gear transmission device on rolling forming equipment, in particular to a variable center distance gear transmission device of a hemming flat steel forming machine. Background technique [0002] The steel grating pressure welding machine press-welds the flat steel and the cross bar to make the original steel grating, cuts it according to the specified length, and welds it with the edge-wrapped flat steel to form a finished steel grating. [0003] The steel grating automatic edge wrapping machine completes the welding of the steel grid plate and the edge-wrapped flat steel. The difference from the manual welding method is that the edge-wrapped flat steel needs to have long strips that meet the requirements of resistance welding. The edge-wrapped flat steel forming machine is The long flat steel is rolled into a special wrapping flat steel. The center distance of the gear transmission device used in the existing hemming flat s...
