본 고안은 펌프의 회전축에 회전차를 고정설치토록한 펌프의 회전차 고정장치에 관한 것이다.The present invention relates to a rotary car fixing device for the pump to be fixed to the rotary shaft of the pump.
종래에는 제 6 도에 표현한 바와같이 펌프의 회전축(100)에 회전차(101)를 고정설치하기 위하여 회전축(100)에 키이(102)를 이용하여 고정하고, 또한 회전축(100)의 선단부에 단부(103)를 형성하며 이에 나사(104)를 형성하여 캡(105)을 나착함으로써 회전차(101)를 고정설치토록 구성하여서 된 것이다.In the related art, in order to fix and install the rotary car 101 on the rotary shaft 100 of the pump as shown in FIG. 6, it is fixed using the key 102 on the rotary shaft 100, and the end portion of the rotary shaft 100 ends. And forming a screw 104 to attach and attach the cap 105 to fix the rotary car 101.
이와같이 구성된 종래의 고안은 회전축(100)에 회전차(101)를 고정설치시키기 위하여 키이(102)와 단부(103) 및 나사를 형성한 캡(105)을 필요로함으로 과다한 공정이 투입되고, 회전축(100)을 불필요하게 굵게 하여야 하며 조립시 및 유지 보수시에는 회전차(101)의 위치설정이 어려워지는 등의 문제점이 있었다.The conventional design configured as described above requires an excessive process by inserting a key 102, an end 103, and a cap 105 having a screw in order to fix the rotary car 101 on the rotary shaft 100, and the rotary shaft Unnecessarily thickened (100) and had problems such as difficult positioning of the rotor wheel 101 during assembly and maintenance.
본 고안은 상기와 같은 종래의 문제점을 감안하여 회전축(100)에 회전차(101)를 고정설치하기 위한 수단으로서 키이(102)와 단부(103) 및 캡(105)을 필요로 하지 아니하고 회전축에 아답터스리브를 삽입하여 이에 고정너트와 고정와셔 및 고정크립을 이용하여 회전차를 고정설치토록 하였는바, 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.The present invention does not require the key 102, the end 103 and the cap 105 as a means for fixing the rotary car 101 to the rotary shaft 100 in view of the conventional problems as described above to the rotary shaft By inserting the adapter ribs were fixed to the rotary car using a fixing nut, a fixing washer and a fixing creep bar, as described in detail by the accompanying drawings as follows.
펌프의 회전축(1)에 삽입설치되는 회전차(2)의 보스부(3) 삽입공(4)을 테이퍼형으로 형성하고, 이에 축삽입공(5)을 갖고 나사부(6)를 형성하며 테이퍼를 형성한 아답터스리브(7)를 삽입한다. 또한 괴지홈(8)을 형성한 고정너트(9)를 상기 아답터스리부(7)의 나사부(6)에 나착한다. 그리고 걸림편(10)을 형성한 고정와샤(11)를 상기 아답터스리브(7)에 삽입하여 고정너트(11)의 괘지홈(10)에 걸림편(10)이 삽입하여 고정너트(9)의 풀림을 방지할 수 있도록 구성하여서 된 것이다. 상기 고정너트(9)의 풀림을 방지하기 위한 고정 수단으로 본 고안에서는 또다른 실시예로써 제 4 도와 제 5 도에 표현하였다. 이에 의하여 설명한다.The boss portion (3) insertion hole (4) of the rotor wheel (2) to be inserted into the rotary shaft (1) of the pump is formed in a tapered shape, and has a shaft insertion hole (5) to form a screw portion (6) and taper Insert the adapter rib (7) formed. In addition, the fixing nut 9 having the recessed grooves 8 is attached to the threaded portion 6 of the adapter three. Then, the fixing washer 11 having the locking piece 10 is inserted into the adapter rib 7 so that the locking piece 10 is inserted into the locking groove 10 of the fixing nut 11 so that the fixing nut 9 It is designed to prevent loosening. As a fixing means for preventing the loosening of the fixing nut 9 in the present invention is shown in FIG. 4 and FIG. This demonstrates.
상기 아답터스리부(7)의 축삽입공(5)상부와 체결용나사(12)를 형성한 고정너트(9)의 외면에는 서로 대응하는 고정홈(13)(13)을 각각 형성하며 이에는 고정크립(14)을 삽입하여 체결나사(15)로서 체결 고정하여서된 구성이다.Fixing grooves 13 and 13 corresponding to each other are formed on the outer surface of the fixing nut 9 having the upper part of the shaft insertion hole 5 of the adapter three and the fastening screw 12 formed thereon. The fixing creep 14 is inserted into the fastening screw 15 to be fastened and fixed.
이와같이 구성된 본 고안의 작용효과를 설명한다.The effect of the present invention configured as described above will be described.
회전축(1)에 삽입된 회전차(2) 보스부(3)의 삽입공(4)을 테이퍼형으로 형성하고 이에 페이퍼를 가진 아답터스리브(7)를 삽입하고 아답터스리브(7)의 나사부(6)에 고정너트(9)를 체결하여 조이게되면 아답터스리브(7)는 테이퍼를 가진 회전차(3)의 삽입공(4)을 따라 상승하면서 회전축(1)과 아답터스리브(7) 및 회전차(2)는 견고하게 고정이되며, 이때 고정너트(9)의 외면 괴지홈(8)에 고정와셔(11)의 걸림편(10)이 삽입하여 고정될수 있도록 아답터스리브(7)에 삽입하여 회전차(2) 보스부(3)의 상단면에 안착시킴으로써 상기 고정너트(9)의 풀림을 방지하여 견고하게 고정설치할수 있는 것이다. 또한 회전축(1)을 불필요하게 굵게 하거나 단부(103)를 없애 과다한 공정의 투입을 방지하여 작업공수를 줄이며 특히 조립 및 유지 보수시 회전차(2)의 위치설정을 이용이하게 할 수 있는 특징으로 지닌 것이다.The insertion hole 4 of the boss 3 of the rotor wheel 2 inserted into the rotary shaft 1 is formed into a tapered shape, and an adapter rib 7 having a paper is inserted thereinto, and the thread 6 of the adapter rib 7 is inserted therein. When the fixing nut (9) is tightened to tighten the adapter nut (7) is raised along the insertion hole (4) of the rotary wheel (3) having a taper while rotating shaft (1) and adapter rib (7) and rotary car ( 2) is firmly fixed, and the rotor wheel is inserted into the adapter rib 7 so that the locking piece 10 of the fixing washer 11 can be inserted into the outer gripping groove 8 of the fixing nut 9 so that the locking piece 10 can be fixed. (2) By being seated on the upper end surface of the boss portion (3) to prevent the loosening of the fixing nut (9) it can be firmly fixed installation. In addition, the rotary shaft 1 is unnecessarily thickened or the end 103 is eliminated to prevent excessive operation of the process, thereby reducing the labor and in particular, the position of the rotor 2 can be easily used during assembly and maintenance. I have it.
그리고, 본 고안의 또다른 실시예에 대한 작용효과를 설명하면 다음과 같다.And, when explaining the operation and effect for another embodiment of the present invention as follows.
상기 고정너트(9)가 회전축(1)과 아답터스리브(7) 및 회전차(2)를 견고하게 고정하기 위하여 아답터스리브(7)의 상단부에 형성한 나사부(6)에 체결고정케 한후 상기 고정너트(9)와 아답터스리브(7)의 축삽입공(5)에 형성한 고정홈(13)(13)에 고정크립(15)을 삽입하여 체결나사(15)로써 체결고정하여 고정너트(9)의 풀림을 방지하므로써 견고하게 고정할 수 있는 것이다. 이하의 효과는 상기 기술한 내용과 동일하다.The fixing nut 9 is fastened to the screw part 6 formed at the upper end of the adapter rib 7 in order to securely fix the rotating shaft 1, the adapter rib 7, and the rotor difference 2. The fixing nut (15) is inserted into the fixing groove (13) and the fixing groove (13) formed in the shaft insertion hole (5) of the nut (9) and the adapter rib (7). It can be fixed firmly by preventing loosening. The following effects are the same as those described above.
