The utility model provides a half axle sleeve of both ends flange formula pump shaft with dividing, its includes first half axle sleeve and second half axle sleeve, its characterized in that: the first half shaft sleeve and the second half shaft sleeve respectively comprise a first semicircular ring at two ends and a second semicircular ring at the middle part, the first half shaft sleeve and the second half shaft sleeve are connected through a connecting mechanism in a half way, and the connecting mechanism comprises a sinking groove arranged in the first semicircular ring of the first half shaft sleeve and a connecting screw arranged in the sinking groove; the middle parts of the first half shaft sleeve and the first half ring of the second half shaft sleeve are respectively provided with an anti-rotation screw.
It is further characterized by:
The connecting screw is provided with an anti-loosening connecting piece, one end of the anti-loosening connecting piece is connected with the top end of the connecting screw through an anti-loosening bolt, and the other end of the anti-loosening connecting piece is connected with the groove wall at the bottom of the sinking groove through an anti-loosening positioning pin;
A conical surface is arranged at the joint of the first semicircular ring and the second semicircular ring;
The outer wall of the half joint of the first half shaft sleeve and the second half shaft sleeve is provided with an inward-bending arc;
The pump shaft is provided with a mounting section for mounting the half-type shaft sleeve, the length of the half-type shaft sleeve is slightly smaller than that of the mounting section, and the diameter of the middle section of the mounting section is slightly smaller than that of the inner diameter of the half-type shaft sleeve;
The outer diameter and the inner diameter of the first semicircular ring are smaller than those of the second semicircular ring.
After the structure is adopted, the two halves of the half-type shaft sleeve and the connecting mechanism are arranged, so that the installation can be completed only by combining and installing the two halves of the half-type shaft sleeve on the pump shaft and then screwing the connecting screw and the locking mechanism, the disassembly can be completed by unscrewing the connecting screw and the locking mechanism and then separating the two halves of the half-type shaft sleeve, the pump shaft is not required to be welded during the installation, the whole unit is not required to be disassembled, the installation and the disassembly processes are convenient and quick, and the time and the labor cost required for maintenance and replacement are reduced.

Detailed Description
The utility model will be further described with reference to the accompanying drawings.
Referring to fig. 1 to 5, a split type shaft sleeve for a pump shaft with flange at two ends comprises a first half shaft sleeve 2 and a second half shaft sleeve 3, wherein the first half shaft sleeve 2 and the second half shaft sleeve 3 respectively comprise a first half ring 11 at two ends and a second half ring 12 in the middle, the outer diameter of the first half ring 11 is smaller than that of the second half ring 12, the inner diameter of the first half ring 11 is smaller than that of the second half ring 12, the first half shaft sleeve 2 and the second half shaft sleeve 3 are connected through a connecting mechanism half, and the connecting mechanism comprises a sinking groove 4 arranged in the first half ring 11 of the first half shaft sleeve 2 and a connecting screw 5 arranged in the sinking groove 4; the connecting screw 5 is provided with an anti-loosening connecting piece, one end of the anti-loosening connecting piece 6 is connected with the top end of the connecting screw 5 through an anti-loosening bolt 7, and the other end of the anti-loosening connecting piece is connected with the bottom groove wall of the sinking groove 4 through an anti-loosening positioning pin 8, so that the connecting screw 5 is prevented from loosening.
The outer wall of the half joint of the first half shaft sleeve 2 and the second half shaft sleeve 3 is provided with an inward-bending arc 14 for avoiding the bearing scraping caused by the occurrence of the offset of the first half shaft sleeve 2 and the second half shaft sleeve 3.
