Description
Technical Field
The utility model belongs to spiral welded tube edge milling machine transmission connection structure's improvement, especially a modified spiral welded tube edge milling machine transmission connection structure.
Background
At present, the commonly used treatment modes of the edge of the strip steel plate in the production of the domestic spiral welded pipe comprise 3 types of edge cutting, edge planing and edge milling. The edge milling process has the advantages of low plate consumption, high yield, high welding quality, high safety and the like, is favorable for eliminating the crescent defect of the plate, and thus becomes a main mode for processing the edges of the strip steel plate.
The transmission structure adopted by the existing edge milling machine is a cycloid disc steel bushing positioning transmission mode. The transmission mode has large loss to the edge milling machine, the fault parts are all the abrasion of the cycloid discs, the steel sleeves are broken, the bending deformation of the spindle head of the main rotating motor is caused, and the key rolling condition is serious. The service life is short.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a modified spiral welded tube edge milling machine transmission connection structure, its is rational in infrastructure, can reduce the maintenance duration that the cycloid dish was changed to the cycloid dish speed reducer, reduces the deformation and wear of equipment, increases the life of equipment.
The purpose of the utility model is realized like this: the utility model provides a modified spiral weld pipe edge milling machine transmission connection structure, include by spiral weld pipe edge milling machine motor drive's speed reducer, its output shaft of motor drive's gear reducer is connecting driving gear axle through elastic coupling, the driving gear axle is equipped with the output gear axle of milling cutter dish through intermediate gear transmission, install upper and lower bearing through upper and lower bearing position sleeve respectively on the driving gear epaxial shaft hole that sets up respectively on the upper cover of quick-witted case and bottom surface and the shaft hole down, set up the gland on the upper shaft hole, set up gland down on the shaft hole down.
The utility model changes the transmission result of the speed reducer, changes the often damaged cycloid disc, uses the gear speed reducer to fix the upper and lower shaft heads, 1) changes the original cycloid disc speed reducer into the gear speed reducer type; 2) replacing the original connecting shaft sleeve with an elastic coupling; 3) the original equipment transmission shaft only has an upper shaft sleeve, an upper group of bearing positioning sleeves and a lower group of bearing positioning sleeves are added for fixation, and a gland is additionally arranged at the bottom.
The utility model reduces the maintenance time for replacing the cycloid disc of the cycloid disc speed reducer, and reduces the cost of the steel bushing and the cycloid disc; the shaft head of the transmission gear has reduced deformation and abrasion due to the upper and lower bearing locating sleeves.
The utility model discloses it is rational in infrastructure, reduced the maintenance duration that the cycloid dish speed reducer changed the cycloid dish, reduced the deformation wearing and tearing of equipment, increased the life of equipment.
Drawings
The present invention will be further described with reference to the accompanying drawings, and fig. 1 is a schematic view of the structure of the present invention.
