Abstract
The utility model provides a special bearing installing tool for a rotary atomizer. The special bearing installing tool comprises a shaft, a bearing, a sleeve and a lead screw, and a shaft cap installing hole is formed at one end of the shaft. The special bearing installing tool is characterized in that a radial hole is formed at one end of the sleeve and sleeved on the outer wall of the shaft, one end of the sleeve clings to one end of the bearing, a lead screw guide hole communicated with the radial hole is formed at the other end of the sleeve, one end of the lead screw protrudes outwards to be provided with a connecting rod matched with the bearing installing hole, a hexagonal head is arranged at the other end of the lead screw, the diameter of the connecting rod is smaller than that of the lead screw, and the connecting rod of the lead screw is fixedly connected with the shaft cap installing hole after one end of the lead screw penetrates the lead screw guide hole. By the special bearing installing tool, bearing installation accuracy can be guaranteed, bearings are ensured not to be damaged during the whole installation process, and installation efficiency is high.
Description
Technical field
The utility model relates to the technical field of the assembling aid of rotary atomizer, is specially the special-purpose bearing instrument of installing of a kind of rotary atomizer.
Background technology
Generally adopt at present the main equipment of rotary atomizer as the desulfurization depickling in the waste incineration and generating electricity project, it has advantages of that rotating speed is high, power is large, smooth running, can adapt to the running environment of strong acid and strong base, in order to guarantee equipment energy long-time steady operation, the I& M of itself requires also very strict, the particularly installation of two of its inside ceramic thrust bearings, because ceramic segment in bearing is more crisp, excessive axial force or radial load are all likely destroyed bearing.In existing disassembly process, adopt copper bar or copper sleeve to be knocked installation, this kind of method installation accuracy, installation dynamics all are difficult to control, and easily damage bearing, and the inefficiency of installing.
Summary of the invention
For the problems referred to above, the utility model provides a kind of rotary atomizer the special-purpose bearing instrument of installing, and it can guarantee the installation accuracy of bearing, and guarantees that bearing is damaged at whole installation process middle part, and the high efficiency of installing.
The special-purpose bearing instrument of installing of a kind of rotary atomizer, its technical scheme is such: it comprises axle, bearing, sleeve, screw mandrel, one end of described axle has the shaft-cup installing hole, it is characterized in that: an end of described sleeve has radial hole, described radial hole is set in the outer wall of described axle, one end of described sleeve is close to an end of described bearing, the other end of described sleeve has the screw mandrel pilot hole, described screw mandrel pilot hole is communicated with described radial hole, one end evagination of described screw mandrel is provided with and the supporting connecting rod of described bearing mounting hole, the other end of described screw mandrel is provided with turret head, the diameter of described connecting rod is less than the diameter of described screw mandrel, after described screw mandrel one end runs through described screw mandrel pilot hole, its connecting rod screw threads for fastening connects described shaft-cup installing hole, the other end of described screw mandrel exposes to described sleeve, adjusting nut is set in described screw mandrel, described adjusting nut is positioned at the outside of described sleeve, described adjusting nut presses the end face of the other end of described sleeve.
It is further characterized in that: described sleeve is specially the sleeve of PPS material.
After adopting structure of the present utility model, during installation, first bearing is placed in to the end with the shaft-cup installing hole of axle, make afterwards the radial hole of sleeve be set in the outer wall of described axle, one end of sleeve is close to an end of bearing, and after screw mandrel one end runs through described screw mandrel pilot hole, its connecting rod screw threads for fastening connects described shaft-cup installing hole, adjusting nut presses the end face of the other end of described sleeve, promote bearing movable by rotating adjusting nut, it is owing to having used axle, the cooperation in hole is led, avoid when mounted masterpiece except axial force to be used on bearing, can effectively protect bearing not to be damaged, and an end of sleeve is close to an end of bearing, be plane contact between the two, can guarantee the accurate gap of bearing, adjusting nut screws the promotion bearing movable, make bearing in the process compressed stressed evenly, motion is mild, than being easier to the control dynamics and adjusting distance, and installment work efficiency is high, to sum up, it can guarantee the installation accuracy of bearing, and guarantees that bearing is damaged at whole installation process middle part, and the high efficiency of installing.
The accompanying drawing explanation
Fig. 1 is stereogram structural representation of the present utility model;
Fig. 2 is front view structural representation of the present utility model (sleeve is for analysing and observe).
The specific embodiment
See Fig. 1, Fig. 2, it comprises axle 1, bearing 2, sleeve 3, screw mandrel 4, one end of axle 1 has shaft-cup installing hole 5, one end of sleeve 3 has radial hole 6, radial hole 6 is set in the outer wall of axle 1, one end of sleeve 3 is close to an end of bearing 2, the other end of sleeve 3 has screw mandrel pilot hole 7, screw mandrel pilot hole 7 is communicated with radial hole 6, one end evagination of screw mandrel 4 is provided with the connecting rod 8 supporting with bearing mounting hole 5, the other end of screw mandrel 4 is provided with turret head 9, the diameter of connecting rod 8 is less than the diameter of screw mandrel 4, after screw mandrel 4 one ends run through screw mandrel pilot hole 7, its connecting rod 8 screw threads for fastening connect shaft-cup installing hole 5, the other end of screw mandrel 4 exposes to sleeve 3, adjusting nut 10 is set in screw mandrel 4, adjusting nut 10 is positioned at the outside of sleeve 3, adjusting nut 10 presses the end face of the other end of sleeve 3, sleeve 3 is specially the sleeve of PPS material, makes in operating process and can not produce metal fillings, guarantees inner cleaning, and reduces unnecessary wearing and tearing.
