본 발명은 베어링하우징에 관한 것으로, 더욱 상세하게는 각종 산업현장에 설치되어 사용되는 베어링을 지지고정하기 위한 베어링하우징의 본체를 분할 구성하여 조립 사용함으로써, 베어링이 고정 설치되는 베어링고정부의 가공을 용이하게 하여 제품의 정밀도를 높힐 수 있게 되는 동시에 베어링의 장착 및 교환이 용이하게 하여 베어링설치작업의 작업성을 좋게 한 것이다.The present invention relates to a bearing housing, and more particularly, by processing the bearing fixing part in which the bearing is fixed and installed by dividing and assembling the main body of the bearing housing for supporting and fixing the bearing installed in various industrial sites. It is easy to increase the precision of the product and facilitates the installation and replacement of the bearing to improve the workability of the bearing installation work.

일반적으로 회전되는 구동축의 지지를 위해 사용되는 베어링을 고정하기 위한 베어링하우징의 경우, 지금까지는 제6도에 도시한 바와 같이 베어링(B)이 끼워지는 고정부(02)를 중앙에 형성한 하우징본체(01)를 주물등이 제작동법에 의해 하나의 몸체로서 형성하고 구성하고 있는 것인바, 이는 베어링(B)이 끼워져 고정되도록 진원을 이루는 고정부(02)의 내경을 베어링(B)외경과 동일한 상태로 되도록 매우 정밀하게 맞추어 가공 형성하여야 하므로 하우징본체(01)의 제작이 매우 까다로울 뿐만 아니라, 고정부(02)에 베어링(B)을 조립 설치하는 작업 역시 외부에서 외력에 의해 강제로 끼워 넣는 식으로, 조립 설치해야하므로 하우징본체(01)에 대한 베어링(B)의 정교한 설치가 불가능하게 될 뿐만 아니라 하우징본체(10)의 고정부(02)에 베어링(B)을 조립, 설치하는 과정에서 베어링(B)이나 하우징본체(01)가 손상되는 일이 종종 발생하게 되어 경제적인 손실을 초래할 우려가 있으며, 또한 베어링하우징에 대한 베어링(B)의 설치를 위해 소요되는 작업시간이 길어지는등 작업성을 크게 해치게 되는 문제점이 있는 것이었다.In general, in the case of a bearing housing for fixing a bearing used for supporting a rotating drive shaft, the housing main body is formed with a fixing part 02 into which the bearing B is fitted, as shown in FIG. (01) is formed by the casting and the like as a body by a manufacturing method, which is the same as the outer diameter of the bearing (B) the inner diameter of the fixed portion (02) rounded so that the bearing (B) is fitted and fixed Since it must be formed and processed very precisely so as to be in a state, manufacturing of the housing body 01 is very difficult, and the work of assembling and installing the bearing B on the fixing part 02 is also forcibly inserted by external force. In addition, since the installation of the bearing (B) on the housing body (01) is impossible to install, as well as to assemble and install the bearing (B) on the fixing portion (02) of the housing body (10). The bearing (B) or the housing body (01) is often damaged in the process, which may cause economic losses. In addition, the working time required for the installation of the bearing (B) for the bearing housing is increased. There was a problem that greatly hurt the workability.

따라서 본 발명은 상기와 같은 종래 베어링하우징이 지닌 제반문제점을 감안하여, 베어링하우징에 대한 베어링의 조립설치를 보다 용이하고 정교하게 하기 위해 하우징본체를 다닐 몸체가 아닌 베어링씌움구와 베어링받침으로 구분구성함으로써 베어링하우징에 대한 베어링의 조립 설치작업을 보다 용이하고 정교하게 할 수 있게 하여 작업능률을 향상시킬 수 있는 베어링하우징을 제공함을 목적으로 하는 것으로 첨부도면을 참고로 하여 상세히 설명하면 다음과 같다.Therefore, in view of the above problems of the conventional bearing housing as described above, the present invention is divided into a bearing cover and a bearing support rather than a body to carry the housing body in order to more easily and precisely assemble and install the bearing for the bearing housing. The purpose of the present invention is to provide a bearing housing that can improve the work efficiency by making the assembly and installation work of the bearing with respect to the bearing housing easier and more precise.

상기와 같은 구성으로 되는 본 발명에 의한 베어링하우징의 설치사용상태 및 작용효과에 대해 설명한다.The installation use state and the effect of the bearing housing according to the present invention having the above configuration will be described.

베어링(B)의 내주면에 지지할 축(3)이 끼워진 상태에서 본 발명의 베어링하우징(A)을 이용해 베어링(B)을 지지 설치하기 위해서는, 머저 제2도에 도시한 바와 같이 베어링(B)을 본 발명의 베어링하우징(A)을 이루는 베어링받침(2)의 호형부(21)에 밀접되게 설치한 상태에서 그대로 베어링 씌움구(1)의 내면에 형성된 호형부(11)가 베어링(B)의 상부 외면에 밀접되게 설치하는 것인바, 이때 베어링받침(2)과 베어링씌움구(1)는 그 양측의 끼움구(22a)의 끼움터(13a)이 서로 끼워진 상태에서 베어링씌움구(1)의 호형부(11) 양단에 형성된 걸림턱(12)(12)은 베어링받침(2)의 호형부(21) 양 끝단면과 밀접되고, 또한 베어링씌움구(1) 하부양측의 안착부(14)(14)내에 형성된 삽입홈(15)(15)내에 베어링받침(2)양단의 끼움돌기(23)(23)가 각각 끼워져 결합되는 상태로 되어 제2도 및 제3도에 도시한 바와 같이 양 호형부(11)(12)는 베어링(B)의 외경과 동일한 직경의 전원을 형성하면서 베어링(B)을 상하로 협지, 지지할 수 있게 되는 것이다.In order to support and install the bearing B using the bearing housing A of the present invention while the shaft 3 to be supported on the inner circumferential surface of the bearing B is fitted, as shown in FIG. Is formed in the inner surface of the bearing cover (1) in the state in which it is closely installed to the arc portion 21 of the bearing support (2) constituting the bearing housing (A) of the present invention bearing (B) It is to be installed closely to the upper outer surface of the bearing support (2) and the bearing cover (1) is the bearing cover (1) in the state in which the fitting groove (13a) of the fitting holes (22a) of both sides are fitted The locking jaws 12 and 12 formed at both ends of the arc portion 11 of the bearing support 2 are in close contact with both end surfaces of the arc portion 21 of the bearing support 2, and the seating portions 14 on both sides of the lower portion of the bearing cover 1 are provided. 2) and 3) in which the fitting protrusions 23 and 23 of both ends of the bearing support 2 are respectively inserted into the insertion grooves 15 and 15 formed in the Amount arc portion 11, 12 as shown will be able to be held between the support up and down the bearing (B), forming a supply of the same diameter as the outer diameter of the bearing (B).

이때 베어링씌움구(1)상부에 설치된 오일코크(4)를 통해 상기 협지, 지지되는 베어링(B)외면으로 오일을 공급하게 되면 공급되는 오일은 베어링 씌움구(1) 및 베어링받침(2)내부에 형성된 요홈부(11a)(21a)내로 공급되게 된다.At this time, if the oil is supplied to the outer surface of the bearing (B) supported through the oil coke (4) installed on the bearing cover (1), the supplied oil is inside the bearing cover (1) and the bearing support (2). It is supplied into the grooves (11a) (21a) formed in the.

이 상태에서 베어링하우징(A)을 양측의 받침부(14)(14)에 형성된 고정구멍(16)(16)을 통해 볼트등의 별도의 고정수단으로서 기대(基臺)에 설치하게 되면 베어링받침(2)은 베어링(B)을 받쳐주는 상태로 베어링씌움구(1)의 내부에서 견고하게 고정된 상태를 유지하게 되면서 베어링(B)이 설치된 베어링하우징(A)의 설치는 모두 완료되게 되는 것이다.In this state, when the bearing housing A is installed on the base as a separate fixing means such as a bolt through the fixing holes 16 and 16 formed in the supporting parts 14 and 14 on both sides, the bearing support A is supported. (2) is to support the bearing (B) while maintaining the state of being firmly fixed in the inside of the bearing cover (1) is to complete the installation of the bearing housing (A) in which the bearing (B) is installed .

이와 같이 하여 설치된 베어링하우징(A)내의 베어링(B)을 교환하기 위해 베어링하우징(A)으로부터 베어링(B)을 분리해내고자 할 경우에는, 먼저 베어링영역부(1)의 안착부(14)(14)에 체결된 고정수단을 풀어 베어링하우징(A)을 기대로부터 자유로운 상태로 한 후 안착부(14)(14)하측에서 베어링받침(2)의 양단에 설치된 끼움돌기(23)(23)에 형성된 요입홈(23a)에 별도의 공구를 끼운 상태에서 베어링씌움구(1)를 지렛대식으로 들어올리게 되면 베어링씌움구(1)의 베어링받침(2)은 간단히 분리되면서 베어링하우징(A)을 이루는 베어링씌움구(1)의 베어링받침(2) 양자가 분리상태로 되어 그 상태에서 베어링(B)이 끼워설치된 축(3)을 들어내고 축(3)에 끼워진 베어링(B)을 새로운 베어링(B)으로 교환한 후 다시 앞서 설명한 바와 같이 베어링 받침(2)과 베어링씌움구(1)로서 베어링(B)을 지지 설치하면 베어링(B)의 교체작업 역시 신속하고 간편하게 이루어질 수 있게 되는 것이다.In order to remove the bearing B from the bearing housing A in order to replace the bearing B in the bearing housing A thus installed, first, the seating portion 14 ( 14) release the fixing means fastened to the bearing housing (A) free from the expectation, and then to the fitting projections (23) (23) installed at both ends of the bearing support (2) from the bottom of the seating portion (14) (14) Lifting the bearing cover 1 in a state in which a separate tool is inserted into the formed recess 23a, the bearing support 2 of the bearing cover 1 is simply separated to form a bearing housing A. Both bearing support (2) of the bearing cover (1) is in a detached state, and in that state lifts the shaft (3) on which the bearing (B) is fitted and replaces the bearing (B) fitted on the shaft (3) with a new bearing (B). ), And as shown previously, the bearing support (2) and bearing cover (1) When you install the support ring (B) replacement of the bearing (B) will also be able to be made quickly and easily.

이상의 설명에서 분명히 알 수 있듯이 본 발명의 베어링하우징에 의하면, 베어링을 지지설치하는 베어링하우징을 베어링받침과 베어링씌움구로서 분할 구성하여 베어링을 상하에서 협지 고정토록 함으로써 베어링하주잉에 대한 베어링의 설치 및 교체를 용이하게 하는 동시에 베어링하우징에대한 정밀한 제작이 이루어지게 되므로 보다 정교한 기기 설치가 가능하게 되는 등의 유용한 효과를 제공한다.As is apparent from the above description, according to the bearing housing of the present invention, the bearing housing for supporting the bearing is divided into a bearing support and a bearing cover so that the bearing is clamped up and down so that the bearing can be installed and mounted on the bearing housing. At the same time, it is easy to replace and precise manufacturing of the bearing housing is made, which provides useful effects such as more sophisticated device installation.
