Abstract
The utility model discloses a combined shaft lining, which aims to solve the problem of difficult installation or difficult replacement when the existing integrated shaft lining meet a journal of which both ends are provided with shaft shoulders or locating pieces and to provide the combined shaft lining having the advantages of simple installation and high work efficiency. The utility model has the technical proposal that the combined shaft lining comprises more than two sub bodies of the shaft lining, wherein the interior structures of the sub bodies are in the shape of circular arcs. When combined together, the sub bodies of the shaft lining become a cylindrical surface with a notch groove. A cylindrical surface or a conical surface with a notch groove is formed in the exteriors of the sub bodies of the shaft lining. The sub bodies of the shaft lining can tightly hug journals. After the notch grooves are leveled up through metallic repairing agent, a bearing or other components can be arranged. The shaft lining is suitable for journals of which the two ends are provided with shaft shoulders or locating pieces and simultaneously, the shaft lining is also suitable for the installation of shaft linings of big sizes. The manufacturing and processing accuracy of the shaft lining is far lower than that of the existing integrated linings. The utility model has the advantages of reliable assembling effect, economy, applicability and easy dismounting and installation. The shaft lining is suitable for electromechanical industry and particularly suitable for shaft linings matched with shafts of big diameters.
Description
Technical field
The utility model relates to a kind of muff, especially relates to a kind of built-up shaft lining of installing on different axle journals of being suitable for.
Background technique
Present muff used in electromechanical industries all is to adopt integral body.Muff installs on the axle, bearing or other parts is installed on the muff again, and the muff of this structure has the shaft shoulder or locating piece at axle journal one end, and the other end is feasible during for optical axis; If but the axle journal two ends all have the shaft shoulder or locating piece, just can't the installation shaft lining; The muff size that perhaps has is big, and weight is big, and the quality of fit of lining and axle journal requires high, then makes, mounts and dismounts all very difficult.
The model utility content
The purpose of this utility model provides a kind of corresponding problem that can solve the used muff of axle of different size, and is easy to the built-up shaft lining making, install and dismantle.
For achieving the above object, the utility model has adopted following technological scheme: a kind of built-up shaft lining, its characteristics are: comprise that two or more axle bushes are provided with according to the order of sequence, described axle bush is the arc body of equal thickness, its two ends are provided with connecting hole, by described connecting hole axle bush are connected to form sleeve each other.
Above-mentioned built-up shaft lining, its characteristics are: described axle bush can be connected by bolt each other, also can be connected or otherwise be connected by the rivet rivet clasp.
Above-mentioned built-up shaft lining, its characteristics are: described muff is inboard to be arc surface, and the external diameter of itself and axle journal fits, and described muff outside can be cylinder, and its cylinder can be cylndrical surface or prismatic surface, also can be conical surface or pyramidal surface.
Above-mentioned built-up shaft lining, its characteristics are: the described axle bush place of being connected with each other is formed with the breach ditch, and its breach ditch place is filled with the metal mending binder.
The beneficial effects of the utility model are: this is simple in structure, be easy to install, both being suitable for the axle journal two ends all has the shaft shoulder or locating piece, also is suitable for the use and the maintenance of the muff of big specification, and it is not high to make requirement on machining accuracy, is lower than the machining accuracy of existing whole lining.
Concrete installation of the present utility model is provided with two or more axle bushes according to the order of sequence, with bolt it is serially connected, and screws bolt, makes axle bush hold axle journal tightly, till reaching requirement; Also can adopt rivet or alternate manner to connect connecting between axle bush and the axle bush.After being connected between axle bush and the axle bush, formed the breach ditch at the axle bush place that heals up, can inject in the breach ditch its flat closing with the metal mending binder of selling on the market.Then, just can adorn bearing or other parts.
Adopt the utility model, the axle journal two ends have the axle of the shaft shoulder or locating piece, need not process the shaft shoulder or remove locating piece, and previous condition that can retainer shaft also needn't be removed the affiliated facility on the axle; Simultaneously, if when the muff specification is big, help making and the mounting or dismounting operation.

Embodiment
Embodiment one
As shown in Figure 1 and Figure 2: the utility model is combined by axle bush 1 and 2 two splits of axle bush, and the muff internal structure is cylndrical surface jaggy, and the bottom surface diameter of cylndrical surface is the diameter of institute's engage journal just; During installation, as Fig. 5, shown in Figure 6, axle bush 1 and axle bush 2 are in the symmetrical position of axle journal, and the intrados of axle bush 1 and axle bush 2 and axle journal 5 are coincide, and with bolt 4 axle bush 1 and axle bush 2 are stringed together by tapped hole 3, screw bolt 4 again, axle bush 1 and axle bush 2 are moved closer to, up to holding axle journal 5 tightly; At the place that heals up of axle bush 1 and axle bush 2, leaving certain gaps uncovered by the economic plan ditch 6, added metal is repaired binder 7 in breach ditch 6, and this metal binding agent 7 is a public offering on the market.
Embodiment two
As shown in Figure 3, Figure 4, the utility model is combined by axle bush 1 ', axle bush 2 ' each two four split, and the structure and the size of four splits are just the same, its use and installation identical with embodiment one.This combining form more is applicable to the muff of super large standard.
Among the above embodiments one and the embodiment two, the breach ditch 6 that stays after connecting between the axle bush split, its width can be determined on a case-by-case basis; What of through hole 3 also can determine how many its tapped holes offers according to shaft diameter size, purposes difference and to the specific (special) requirements of engineering.
External shape of the present utility model can design as required, and embodiment one is a column, can be designed as cylindric or prism-shaped; Can also be designed to taper, comprise coniform or pyramid-shaped, the tapering of its taper is made as between 1: 8~1: 50, as Fig. 7, shown in Figure 8.Embodiment two is a taper, can be designed as coniform or pyramid-shaped; Also can be designed as column, comprise cylindric or prism-shaped, as Fig. 5, shown in Figure 6.
