Abstract

The utility model discloses a bearing hole repair device of a water pump bearing box. The bearing hole repair device of the water pump bearing box comprises a bearing hole for mounting a bearing, the diameter of the bearing hole is increased through chambering, a shaft housing is mounted in the bearing hole and is in interference fit with the bearing hole, the length of the shaft housing is equal to the depth of the bearing hole, locating holes are uniformly formed in the head face of the bearing hole along the outer surface of the shaft housing, the depth of each locating hole is equal to that of the bearing hole, and a locating pin is mounted in each locating hole and is in interference fit with the locating hole. The shaft housing is integrated with the bearing hole, locating pins are mounted at the outer surface of the shaft housing so that the circumferential rotation of the shaft housing is limited, and equivalently, the abrasion of the bearing hole is restored, and the rotary bearing restores to the initial state. The bearing hole repair device is capable of quickly repairing the fretted bearing hole, the bearing hole can be quickly put into production, and the production is not influenced.

Description

A kind of water pump bearing axle box bearing hole prosthetic device

Technical field

The utility model relates to a kind of water pump bearing axle box bearing hole prosthetic device.

Background technology

Pump operation parts one end adopts bearing spacing, can not move, and the other end can move axially by trace.The water pump that dams of sewage device, in the running of production run high speed, produces high temperature and thermal expansion while running up body bearing operation, has certain amount at intermittence between bearing and bearing housing dead eye, and free-extension regulates vertically, can continuous high speed running.But equipment is in service in long-term production, between operating shaft bearing outer-ring and bearing housing dead eye, there is micro-relative motion, after operation certain hour, bearing housing dead eye also has certain wearing and tearing, wear extent exceed a certain amount of after, vibration aggravation, the sound strengthens, formed equipment deficiency, need to carry out equipment replacement spare part, otherwise equipment just can not continue operation or scrap.Change spare part if adopted, carry out spare parts purchasing by spare parts purchasing program, from doing service parts planning to spare part arrival, need long time, will have a strong impact on production run, spare parts purchasing is returned enterprise has in addition increased maintenance of equipment cost.

Summary of the invention

For the deficiencies in the prior art part, the utility model aims to provide a kind of water pump bearing axle box bearing hole prosthetic device, guarantees to repair fast bearing axle box bearing hole, improves the service life of bearing housing.

For solving the problems of the technologies described above, the technical solution adopted in the utility model: a kind of water pump bearing axle box bearing hole prosthetic device, comprise for bearings mounted dead eye, reaming increases 5-8 millimeters of dead eye diameters, then axle sleeve is set in dead eye, it between axle sleeve and dead eye, is interference fit, the length of axle sleeve is suitable with the degree of depth of dead eye, along sleeve outer surface, locating hole is evenly set at dead eye end face, the degree of depth of locating hole is suitable with the dead eye degree of depth, alignment pin is set in locating hole, and alignment pin and locating hole are interference fit.

Adopt technique scheme, axle sleeve and dead eye form one, and the alignment pin arranging at sleeve outer surface, has limited the circumferential rotation of axle sleeve, and the wearing and tearing that are equivalent to dead eye are restored, and the bearing that makes to turn round returns to equipment original state.

The utility model can be repaired the dead eye of wearing and tearing fast, can put into production rapidly, does not affect production.

Brief description of the drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the left view of Fig. 1;

In accompanying drawing: 1 water pump bearing case 2 axle sleeve 3 alignment pin 4 rotating shaft 5 bearings.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figure 1 and Figure 2, there is dead eye both sides at water pump bearing case 1, in dead eye, be equipped with bearing 5, in bearing, be equipped with rotating shaft 4, adopt left side one end bearing 5 spacing, water pump bearing case 1 was worked after the regular hour, between the outer ring of left side bearing 5 and dead eye, had wearing and tearing, thereby produce gradually larger axis and hold hole noise, need to repair it, first to original dead eye counter bore diameter, make dead eye diameter increase 5-8 millimeters, then at dead eye, axle sleeve 2 is set, it between axle sleeve 2 and dead eye, is interference fit, the length of axle sleeve 2 is suitable with the degree of depth of dead eye, along sleeve outer surface, locating hole is evenly set at dead eye end face, because on dead eye end face, axle sleeve 2 is a circle with the contact-making surface of dead eye, taking the point on the outline line of this circle as the center of circle, the locating hole of 3 φ 6 of processing, the degree of depth of locating hole is suitable with the dead eye degree of depth, in locating hole, assemble the alignment pin 3 of 3 φ 6, alignment pin 3 is interference fit with locating hole, on dead eye end face, again by alignment pin 3 and water pump bearing case 1 reinforcement of weld.

Claims

1. a bearing housing dead eye prosthetic device, comprise for bearings mounted dead eye, it is characterized in that: reaming increases 5-8 millimeters of dead eye diameters, axle sleeve (2) is then set in dead eye, between axle sleeve (2) and dead eye, it is interference fit, the length of axle sleeve (2) is suitable with the degree of depth of dead eye, along sleeve outer surface, locating hole is evenly set at dead eye end face, the degree of depth of locating hole is suitable with the dead eye degree of depth, at locating hole, alignment pin (3) is set, alignment pin (3) is interference fit with locating hole.
