본 고안은 안(安 ) 레이스(Race) 와 겉레이스로 베아링을 보호하므로서 베아링에 먼지등의 이물질이 끼이는 것을 방지하고 또 안레이스의 몸체를 길게 형성하여 너트의 조임에 의한 베아링의 압박을 방지토록한 소형바퀴에 관한 것이다.The present invention protects the bearings with an inner race and an outer race to prevent foreign substances such as dust from being caught on the bearings, and the body of the inner race is formed to prevent the pressure of the bearings by tightening nuts. It's all about small wheels.
종래의 소형바퀴는 "제4도"에서와 같이 베아링접시(2)를 바퀴축(1)에 축삽하여 베아링접시(2) 고정너트(4)를 나착한 것이므로 틈사이로 진입된 먼지등의 이물질이 베아링(3)에 끼어들어 바퀴의 원활한 회전을 저해하고 또 고정너트(4)에 의하여 베아링접시(2)가 직접 압박을 받고 있으므로 고정너트를 강하게 조이면 베아링접시(2)와 함께 베아링(3)도 압박을 받으므로 회전이 원활하지 못하고 고정너트(4)를 느슨하게 조이면 바퀴가 흔들리게 되므로 적절한 정도로 고정너트(4)를 조이는 것이 기술적으로 매우 어려운 단점이 있는 것이었다,In the conventional small wheel, the bearing plate 2 is inserted into the wheel axle 1 as shown in FIG. 4 so that the bearing plate 2 and the fixing nut 4 are attached to each other. The bearing plate 2 is impeded by the bearing 3 to prevent the smooth rotation of the wheel and the bearing plate 2 is directly pressed by the fixing nut 4 so that the bearing nut 3 together with the bearing plate 2 can also be tightened. Since the rotation is not smooth and the fixing nut 4 is loosely tightened because the wheel is shaken, it is technically very difficult to tighten the fixing nut 4 to an appropriate degree.
본 고안은 이러한 단점들을 시정하기 위하여 안출한 것으로서 첨부도면에 따라 상세히 설명하면 다음과 같다.The present invention is devised to correct these disadvantages, and will be described in detail according to the accompanying drawings.
중앙부가 돌출되어 돌출부(13)와 요입부(14)로 형성된 소형바퀴(11)의 축공(12)에 요홈(15)이 환설된 2개의 원통형 안레이스(16)(17)를 양측에서 삽설하되 안레이스(16)(17)의 몸체를 길게 형성하여 일측단부(16')(17')가 축공(12)의 밖으로 약간 돌출되게 하고 그 타단은 축공(12)의 중앙에서 서로 당접되게 하였으며, 안레이스(16)(17)와 대칭으로 요홈(18)이 환설된 겉레이스(19)에 통상의 방법으로 베어링제트(20)를 결합하고 요홈(15)과 요홈(18)사이에 베아링(21)이 유설되게 겉레이스(19)를 축공(12)의 요입부(14)에 삽착하여서 된 것이다.The center portion protrudes and inserts two cylindrical inner races 16 and 17 in which the grooves 15 are recirculated in the shaft hole 12 of the small wheel 11 formed of the protrusion 13 and the inlet 14. The body of the non-lace 16, 17 is formed long so that one end portion 16 ', 17' slightly protrudes out of the shaft hole 12, and the other end is abutted with each other at the center of the shaft hole 12, The bearing jet 20 is coupled to the outer race 19 in which the grooves 18 are symmetrical with the non-laces 16 and 17 in a conventional manner, and the bearing 21 is disposed between the grooves 15 and the grooves 18. ) Is made by inserting the outer race 19 into the recessed portion 14 of the shaft hole (12).
미설명부호(22)는 축봉(23)은 와샤(24)는 고정너트(25)는 외주면이 "T-1" 형으로 돌설된 림(Rim) (26)은림과 게합된 외주륜(27)은 바퀴에 삽착된 카버이다.Unexplained reference numeral 22 is the shaft 23, the washer 24, the fixing nut 25 is the outer rim rim (26), the outer peripheral surface protruding in the form of "T-1" (27) the outer circumference ring 27 and the rim Is a carver mounted on a wheel.
이와같이 구성된 본 고안은 베아링(21)이 베아링제트(20)와 결착된 겉레이스(19)와 안레이스(16)(17)에 의하여 보호되고 있으므로 외부로부터 먼지와 이물질이 베아링(21)에 끼어 바퀴(11)의 원활한 회전을 저해하고 베아링(21)의 마모를 가소화하는 폐단을 방지하였고, 또 안레이스(16)(17)의 양단부(16')(17')가 고정너트(24)로부터 베아링(21)이 압박을 받지 않도록 지지하고 있으므로 고정너트(24)를 안심하고 죄어도 베아링(21)의 회전이 원활한 등의 효과가 있는 것이다.Since the bearing 21 is protected by the outer race 19 and the inner race 16 and 17 attached to the bearing jet 20, dust and foreign matter are caught in the bearing ring 21 from the outside. (11) prevents the closed end which prevents smooth rotation of the bearing 21 and plasticizes the wear of the bearing 21, and both ends 16 'and 17' of the anise race 16 and 17 are removed from the fixing nut 24. Since the bearing 21 is supported so as not to be pressurized, even if the fixing nut 24 is tightened with confidence, the bearing 21 is rotated smoothly.
