Abstract

본 발명은 온수(유체)를 강제순환시키는 온수순환펌프에 있어서, 샤프트를 지지하는 베어링을 전혀 새로운 개념의 베어링에 관한 것으로서, 모터하우징(10)의 고정자(11)에 전원이 입력되면 샤프트(13)에 축착된 회전자(12)가 회전되고, 상기 샤프트(13)의 상측에 축착된 임팰러(5)가 모터앤드쉴드(14)에 의해 분해된 펌프하우징(2)의 임팰러실에서 회전되면서 온수를 강제순환 시키도록 된 것에 있어서, 샤프트(13)와 모터앤드쉴드(14) 및 베어링하우징(15) 사이에 끼워지는 베어링을 내베어링(23)과 외베어링(20)을 분할하되 이들 연접면을 슬립만곡면(25) 및 만곡요면(21)으로 형성하는 것과, 내베어링(23)을 플랜지(27)에 받침편(28)이 돌설된 베어링받침링(26)으로 받쳐주도록 된 것인바, 온수순환펌프(1-1)가 작동되어지는 동관 내·외베어링(23)(20)의 슬립만곡면(25)과 만곡요면(21) 사이에 수막이 형성되어 마찰 손실이 배제되므로 보다 강한 추력을 발생시킬수 있고, 압력상태에 따라 상하측의 베어링받침링(26) 상호보완적으로 탄력 있게 탄발되어지므로 수막에 의해 내베어링(23)이 외베어링(20)에서 일정한 간격을 유지시킬수 있다.The present invention relates to a bearing of a whole new concept in a hot water circulating pump for forced circulation of hot water (fluid). When power is input to the stator 11 of the motor housing 10, the shaft 13 Rotor 12 condensed on the rotating shaft, and the impeller 5 condensed on the upper side of the shaft 13 is rotated in the impeller chamber of the pump housing 2 disassembled by the motor and shield 14 In the forced circulation of hot water, the bearings fitted between the shaft 13, the motor shield 14 and the bearing housing 15 are divided into the inner bearing 23 and the outer bearing 20, but these joint surfaces To form the slip curved surface 25 and the curved concave surface 21, and the inner bearing 23 is to support the bearing support ring 26 protruding from the flange 27 to the support piece 28, The slip curved surface 25 of the inner and outer bearings 23 and 20 of the copper pipe in which the hot water circulation pump 1-1 is operated Since the water film is formed between the curved surfaces 21 to eliminate frictional loss, it is possible to generate stronger thrust, and the bearing bearing ring 26 on the upper and lower sides is elastically elastically complementary to each other due to the pressure. The bearing 23 can maintain a constant gap in the outer bearing 20.
