DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bearing housing, and more particularly to a bearing housing which is divided into a main body of a bearing housing for supporting a bearing used in various industries. The present invention relates to a bearing housing that facilitates processing of a bearing fixing portion to enhance the accuracy of a product, and that facilitates mounting and exchangeability of the bearing, thereby improving workability when installing the bearing.

[0002]

2. Description of the Related Art Generally, a bearing housing for fixing a bearing used for supporting a rotating drive shaft has conventionally been provided with a fixing portion 2 into which a bearing B is fitted as shown in FIG. The housing main body 1 'having a central portion' 1 'is integrally formed by casting or the like. In this case, the inner diameter of the fixed portion 2 'of the perfect circle to which the bearing B is fixed should be processed with the same high precision as the outer diameter of the bearing B, so that it is very difficult to manufacture the housing body 1'. In addition, since the operation of attaching the bearing B to the fixed portion 2 'is also forcibly driven in and attached, it is difficult to precisely mount the bearing B to the housing main body 1'. The bearing B or the housing main body is frequently damaged, which may result in economical loss, and the workability is remarkable, for example, the work time for installing the bearing B on the bearing housing becomes long. There was a problem of being damaged.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. 1 to 3 show an embodiment of a bearing housing according to the present invention.

The bearing housing A on which the bearing B is supported comprises a bearing cover 1 and a bearing support 2 and is separably assembled. The bearing cover 1 has a semicircular arc 11 having substantially the same diameter as the outer diameter of the bearing B to be installed formed on an inner surface thereof, and a concave groove 11a formed on a center line of the arc 11. At both ends of the arc portion 11, locking step portions 12, 12 are provided.
Are formed on the inner surfaces of the extensions 13, 13 extending from the arc 11, and guide steps 13 a, 13 a are formed on the inner surfaces of the extensions 13, 13, and the flanges 1 on both sides of the extensions 13, 13 are formed.
Mounting grooves 15, 15 are formed in 4, 14.

[0007] The bearing support portion 2 includes an arc portion 1.
A semicircular arc portion 21 having substantially the same inner diameter as 1 is formed, and a concave groove portion 21a is formed on the center line of the circular arc portion 21. At both ends of the concave groove portion 21a, a bearing B inserted into the arc portion is formed. A rotation preventing groove 21b for preventing rotation of the case is formed, and at both ends of the main body 22 inserted into the extending portions 13, 13, there are provided a guide portion 22a which is brought into contact with the guide step portion 13a and guided. Coupling protrusions 23, 23 are formed in the mounting grooves 15, 15, respectively.

In the drawings, reference numeral 3 denotes a shaft inserted into the bearing B, and reference numeral 4 denotes recesses 11a, 21a formed on the inner surfaces of the arc portions 11, 21 of the bearing cover 1 and the bearing support 2. An oil cock for supplying oil, reference numeral 16 denotes a fixing hole formed in the flange portions 14 and 14, and reference numeral 23a denotes an engagement groove formed in the coupling projections 23 and 23, respectively.

A description will be given of the installation and use state of the bearing housing according to the present invention having the above-described structure, and the operation and effect thereof. In order to support the bearing B in which the shaft 3 is inserted into the inner peripheral surface by using the bearing housing A, first, FIG.
As shown in FIG.
In a state in which the circular arc portion 11 of the bearing support portion 2 is closely contacted with the circular arc portion 21, the circular arc portion 11 formed on the inner surface of the bearing cover portion 1 is closely mounted on the upper portion of the bearing B. At this time, the bearing support portion 2 and the bearing cover portion 1 are formed at both ends of the arc portion 11 of the bearing cover portion 1 at the same time when the guide portions 22a and the guide step portions 13a on both sides thereof are connected to each other. Locking stepped portions 12, 12 are in close contact with both upper end portions of the arc portion 21 of the bearing support portion 2, and the flange portions 14 on both lower sides of the bearing cover portion 1.
The coupling projections 23, 23 at both ends of the bearing support 2 are respectively coupled into the mounting grooves 15, 15 formed on the lower surface of the 14, so that both arc portions 1 are provided as shown in FIGS.
Reference numerals 1 and 21 form a perfect circle having substantially the same diameter as the outer diameter of the bearing B, and sandwich the bearing B up and down.

Here, when oil is supplied to the outer surface of the sandwiched bearing B via an oil cock 4 installed above the bearing cover 1, the supplied oil is supplied to the bearing cover 1 and the bearing support 2. The bearing B is supplied into the concave grooves 11a and 21a formed therein to enable the smooth operation of the bearing B.

In this state, the bearing housing A is
Fixing holes 16, 1 formed in flange portions 14, 14 on both sides
When the bearing B is installed on the base by another fixing means via the bearing 6, the bearing B can be maintained firmly fixed inside the bearing cover 1 while being supported by the bearing support 2. This completes the installation of the bearing housing A into which the bearing B has been inserted.

When the bearing B is removed from the bearing housing A in order to replace the bearing B in the bearing housing A of the present invention installed as described above, first, the flange portions 14 and 1 of the bearing cover portion 1 are removed.
The bearing housing A is released from the base by releasing the fixing means fastened to the bearing support 4, and then separated into engagement grooves 23 a formed in the coupling projections 23, 23 installed at both ends of the bearing support 2. When the bearing cover 1 is lifted up in a leverage manner and the bearing cover 1 is separated from the bearing support 2 with the tool inserted, the bearing cover 1 and the bearing support 2 constituting the bearing housing A can be easily formed. Is separated into In this state, the shaft 3 fitted with the bearing B is lifted up and replaced with a new bearing B, and the bearing B is again supported by the bearing support 2 and the bearing cover 1 as described above. In this manner, the operation of replacing the bearing B can be performed quickly and easily.

[0013]

As described above, according to the bearing housing according to the present invention, the bearing housing for supporting the bearing is divided into a bearing support portion and a bearing cover portion, and the bearing is sandwiched between the upper and lower portions. Since the bearing can be easily installed and replaced with respect to the bearing housing, and the bearing housing can be manufactured precisely, useful effects such as more sophisticated equipment installation can be achieved.
