However, the conventional main shaft wear-resistant sleeve is generally directly welded on the main shaft, and in the operation of a unit, the clearance between the main shaft wear-resistant sleeve and a sealing element is larger and larger, so that the water leakage of the water turbine is increased, the main shaft needs to be dismounted for maintenance, the measures such as repair welding, grinding and the like can only be adopted, the replacement cannot be carried out, and a great deal of inconvenience is brought to the operation and maintenance of a power station.
Disclosure of Invention
The utility model discloses wear-resisting cover lug weld on the main shaft to main shaft among the prior art, need demolish the main shaft and just can resist the mill cover and carry out maintenance, and wear-resisting cover drawback that can not change provides a divide half formula main shaft and wear-resisting cover seal structure, and this seal structure can make wear-resisting cover dismantle and get off to change the maintenance.
The invention aims to be realized by the following technical scheme: a halving type spindle wear-resistant sleeve sealing structure comprises a spindle and a wear-resistant sleeve, wherein the wear-resistant sleeve is sleeved on the spindle, a positioning hole is formed between the spindle and the wear-resistant sleeve, and a positioning pin is arranged in the positioning hole; the anti-wear sleeve comprises two anti-wear rings of a semicircular structure, contact surfaces of two ends, spliced by the two anti-wear rings, are planes, one end of each anti-wear ring is provided with a slot, one end, facing the contact surface, of each slot is provided with a through hole penetrating through the contact surface, and the other end of each anti-wear ring is provided with a mounting hole formed by sinking towards the inner part of the anti-wear ring from the contact surface; one end contact surface of one of them ring of wearing is equipped with the through-hole and another wear ring is equipped with the one end contact surface contact amalgamation of mounting hole, the central line coincidence of through-hole and mounting hole.
In the scheme, the anti-wear sleeve consists of two anti-wear rings, the two anti-wear rings are symmetrically arranged on the main shaft when the anti-wear sleeve is arranged, the two anti-wear rings are fixedly connected through the bolts, the anti-wear sleeve can be arranged on the main shaft, when the anti-wear sleeve is worn and needs to be replaced and maintained, the fixing bolts between the two anti-wear rings are detached, and the operation is simple and convenient. The slotted arrangement is to facilitate the installation of the bolt from the through hole side to the mounting hole side. And a positioning pin is arranged between the main shaft and the wear-resistant sleeve, so that the axial movement of the wear-resistant sleeve on the main shaft caused by the vibration of the unit is prevented.
Preferably, a sealant is arranged between the main shaft and the wear-resistant sleeve. The sealing performance between the main shaft and the wear-resistant sleeve is enhanced.
Preferably, the through holes in the two antiwear rings are fixedly connected with the through holes in the mounting holes through bolts.
Compared with the prior art, the utility model discloses following beneficial effect has: the anti-wear sleeve consists of two anti-wear rings, and is convenient to disassemble, maintain and replace; and a positioning pin is arranged between the main shaft and the wear-resistant sleeve, so that the axial movement of the wear-resistant sleeve on the main shaft caused by the vibration of the unit is prevented.

The labels in the figure are: 1. A main shaft; 2. an antiwear ring; 3. a through hole; 4. mounting holes; 5. grooving; 6. positioning holes; 7. sealing glue; 8. a contact surface.
Detailed Description
The invention will be further described with reference to the embodiments shown in the drawings to which:
example 1
As shown in fig. 1, a halved spindle wear-resistant sleeve sealing structure comprises a spindle 1 and a wear-resistant sleeve, wherein the wear-resistant sleeve is sleeved on the spindle 1, and a sealant 7 is arranged between the spindle 1 and the wear-resistant sleeve. A positioning hole is formed between the main shaft 1 and the wear-resistant sleeve, and a positioning pin is arranged in the positioning hole 6; the anti-wear sleeve comprises two anti-wear rings 2 of a semicircular structure, contact surfaces 8 at two ends, spliced by the two anti-wear rings 2, are planes, one end of each anti-wear ring 2 is provided with a slot 5, one end, facing the contact surface 8, of each slot 5 is provided with a through hole 3 penetrating through the contact surface 8, and the other end of each anti-wear ring 2 is provided with a mounting hole 4 formed by sinking from the contact surface 8 to the inside of the anti-wear ring 2; one of them wear ring 2 is equipped with the one end contact surface 8 of through-hole 3 and another wear ring 2 is equipped with the 8 contact amalgamation of one end contact surface of mounting hole 4, the central line coincidence of through-hole 3 and mounting hole 4. The two antiwear rings 2 are fixedly connected with the mounting hole 4 through a bolt penetrating through the through hole 3.
In the scheme, when the anti-wear sleeve is required to be installed on the main shaft 1, firstly, the outer surface of the position where the anti-wear sleeve is installed on the main shaft 1 is uniformly coated with the sealant 7, then, the two anti-wear rings are sleeved on the main shaft 1, the relative positions of the anti-wear rings 2 are adjusted, so that the through hole 3 of one anti-wear ring 2 corresponds to the installation hole of the other anti-wear ring 2, and the bolt penetrates into the through hole 3 from the groove 5 and penetrates to the bottom of the installation hole 4 to be screwed.
