Dismounting device and method for speed reducer output flange shaft

Abstract

The invention provides a dismounting device and method for a speed reducer output flange shaft. The problems that in existing flange shaft dismounting methods, much time and labor are consumed, the efficiency is low, self-aligning roller bearings and flange shafts easily get damaged, or the existing flange shaft dismounting methods cannot be applicable to outdoor operation are solved. The dismounting device comprises a fixed disc, a fixed rod, a screw, a flanged nut and a driving unit; the fixed disc is provided with a through first threaded hole in the axial direction, and comprises a flangebody and an annular casing pipe connected with the flange body; the flange body is used for being connected with the front end of a speed reducer cover; the annular casing pipe is used for penetratingthrough a through hole in the end face of the speed reducer cover, and the end stretching out of the through hole and the flanged nut are cooperatively installed; an installation pillar which is in threaded connection with a threaded hole in the end face of the flange shaft is connected to one end of the fixed rod, and a groove is formed in the end of the other end of the fixed rod; a first outerthread matched with the first threaded hole is arranged on the outer surface of the screw; after one end of the screw penetrates through the first threaded hole, the end of the screw is located in the groove; the driving unit is used for driving the screw to rotate.

Description

technical field [0001] The invention belongs to a dismantling device of a reducer, in particular to a dismantling device and method for an output flange shaft of a reducer. Background technique [0002] In the prior art, the structure of a commonly used reducer is as figure 1 As shown, it includes a reducer housing 01 and a reducer cover 02. The front end of the reducer housing 01 is connected to the rear end of the reducer cover 02. The reducer housing 01 is provided with a gear coupling 07. The reducer housing The rear end of the body 01 is connected to the flange shaft 04 through the spherical roller bearing 03, and the flange shaft 04 is provided with a threaded hole 041 on one end surface of the reducer housing 01, and the rear end of the reducer housing 01 is provided with an adjusting screw hole. The circlip 05 of the center roller bearing and the front end of the reducer cover 02 are connected with the dust cover 021. Since the self-aligning roller bearing 03 of the...
