Abstract
The utility model relates to a special tool for assembling small size oil film bearings. The special tool for assembling the small size oil film bearings comprises padding iron and two pieces of claws; the padding iron comprises a projection portion and a round disk portion; the projection portion is arranged in the middle of the round disk portion; the bottom surface of the round disk portion is provided with a T-shaped groove which is communicated with a center of a circle; a T-shaped sliding block is fixedly connected above the claws; and the T-shaped sliding blocks are connected with the T-shaped groove in a sliding mode. The special tool for assembling the small size oil film bearings has the advantages of avoiding property of burnt fingers caused by low temperature bearing bushes, enabling the bearing bushes to be naturally centered and accordingly improving the assembly quality due to the fact that freezing bearing bushes namely two pieces of film bearings are clamped through the two pieces of arc-shaped claws.
Description
Technical field
The utility model relates to filmatic bearing mounting technology field, especially a kind of specific purpose tool for small-sized filmatic bearing assembling.
Background technology
Filmatic bearing is owing to have the transmission accuracy height, radial dimension is little and is applicable to all characteristics of bigger occasion of rotor linear velocity and radial load, and be widely used in pre-finish rolling and the finishing mill roll shaft fit on of high-speed wire production line, the superiority and inferiority of its installation accuracy directly influence operational effect and the service life of filmatic bearing, understand according to limited information, the high line of numerous domestic enterprise all extraordinarily pays close attention to filmatic bearing as the accident part and safeguards.Yet as the filmatic bearing of high-speed rod-rolling mill, the structure external form of its dissection type and thinner wall thickness cause certain degree of difficulty for the assembling of bearing.Common assemble sequence is as follows:
1, will put into 121～150 ℃ of baking oven heating with the eccentric bushing that filmatic bearing matches, be incubated 1～2 hour; After two lobe filmatic bearings (to call the subdivision bearing shell in the following text) are relatively fitted according to assembling form, put with leather sheath, fix the relative position of two lobe bearing shells with this, integral body is put in the temperature control box freezing to-85 ℃ then
2, reach temperature is installed after, eccentric bushing after will heating earlier vertically is positioned on the assembly bench, a people has been with gloves to pinch two lobe bearing shells then, the axis hole of perpendicular alignmnet eccentric bushing and mark line, another people is placed on the bearing shell upper surface with the cylinder table of special use, beats knocking with hand two lobe bearing shells are packed in the eccentric bushing.
In the assembling process, because two lobe liner wall thickness are thinner, positioners such as the alignment pin that does not match or positioning key; And thin-wall bearing shell is risen again and speed of expansion is also very fast, in the hasty operating process, does not note slightly or radial and axial dislocation that misoperation just can produce two lobe bearing shells, and just can influence assembly quality in case produce inconsistent phenomenon, even damage bearing shell.
The utility model content
The technical problems to be solved in the utility model is: do not have the problem of misalignment that cause the location when two lobe bearing shells are in being fitted into eccentric bushing in the prior art in order to overcome, a kind of specific purpose tool for small-sized filmatic bearing assembling is provided, it can be with two lobe bearing shells axially and radial location, make assembling easily, solve problem of misalignment, improve efficiency of assembling.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of specific purpose tool for small-sized filmatic bearing assembling, comprise parallels and two lobe claws, described parallels comprises lug boss and round plate, described boss is in the round plate middle part, and described round plate bottom surface has a T type groove that connects the center of circle; Described claw upper fixed is connected with T type slide block, and described T type slide block is slidingly connected to T type groove.Two lobe claws slide in T type groove, and can be used for the clamping bearing shell (be after filmatic bearing is divided into two lobes, each lobe is bearing shell), difference according to the bearing shell size, claw slides with regard to the energy regulated at will, nip two lobe claws with hand, after two lobe bearing shells being aimed at the endoporus of eccentric bushing, knock the lug boss of round plate top gently with hand hammer, finish up to assembling.
For convenience of the clamping bearing shell, described claw is circular-arc, and the claw internal diameter is more than or equal to the filmatic bearing external diameter.
In order to increase the frictional force of clamping, described claw inner surface posts rubber layer.
From the two ends landing, be set with case on the described round plate when preventing that claw is slidingly connected to T type groove, described case directly upwards has two symmetrical square holes, and described square hole size is more than or equal to T type groove.When changing claw, only need the rotation case, make square hole alignment T type groove, claw just can easily be deviate from like this.
For ease of making, described lug boss and round plate are integral type.
The beneficial effects of the utility model are to the utlity model has following advantage:
1, by the bearing shell of the circular-arc claw clamping of two halves after freezing, both avoided finger by the low temperature bearing shell burn may, can make bearing shell nature centering again, thereby improve assembly quality;
2, together finish axially and radially fixing of bearing shell as parallels and the claw of force transfer body, after bearing shell is aimed at the eccentric bushing endoporus, can knock parallels and finish assembling, action links up, accomplish without any letup, general bearing shell external diameter is less than 150mm, and whole assembling process only needs a people just can finish, save manpower, improved efficiency of assembling.
