구조및일반

Rodend is an instrument used when manufacturing control rod link device which transmits power smoothly under towing andcompressing loads having relatively hard motion Without swinging by the combination of reasonable holder with spherical innerrace mapped like mirror side� it can obtain very soft rotation and rocking motion Rodend has two types: lubricant type type and non�lubricant type type In case of PHS & POS which are lubricant type types� it lubricates properly using lubricating nipple and inparticular� it is mainly used to switching load Lubricating period through nipple can be adjusted by considering load and useenvironment and by monitoring regularly slide or speed between spherical inner race and housing under lubrication NS designs�produces� and sells PHS & POS� and also sells accessories like lubricating nipple Also� in case of non�lubricant type PHST & POST� theycan be used semi�permanently even though not lubricating because they are the types which inserting non�lubricant type specialmaterial into the gap between housing and spherical inner race Because non�lubricant type type doesn’t need to lubricate� it canraise management efficiency� has high load rating due to not having nipple inlet� and can be used properly to where rocking motionis made For PHSG & POSG� spherical plain is inserted in order to bear the environment which use load is high as more than PHS (POS)�� unlike existing product combined with copper alloy bush and ball Spherical plain used to here is manufactured by which housingand ball make high carbon chrome bearing with heat treatment� and can be used safely even in high load NS designs� produces� andsells PHST & POST Also� it manufactures and sells rodend made of stainless steel (SPHST) with the special order

(a)

Dynamic load rating means the critical load which spherical partdoesn’t occur scuffing when rotating and sliding. Dynamic load ratingcan be calculated with following approximate expression under staticload rating (Cs) listed in dimension table.

Selection of axle number should satisfy the two kinds: dynamic loadrating calculated by expression (b) and tolerable load calculated byexpression (a). Static load rating (Cs) indicates the figure calculatedby multiplying tolerable surface pressure to projected area ofspherical part.

P : tolerable load

Cs : static load rating

Basic dynamic rated load rating(Co) of cam follower means the load which rated life rotates � million times when operating camfollower same with �st group and its direction and size don’t change Such value is listed on dimension table

The life of cam follower can be calculated according to following expression:

L = 정격수명(1군의 동일한캠플로워를동일조건으로각각운전하

였을 때 이중의 90%의 캠플로워가 구름피로에 의한

플레이킹을일으키지않고회전가능한총회전수)

L = rated life(It’s a rotatable total rotation number which whenoperating cam follower same with 1st group undersame condition, 90% of those cam followersdoesn’t cause any breaking by driving fatigue)

Lh : life time (lh) Rated life (10° rotation)

방진과윤활

캠플로워는내부로이물질의침입이나윤활제의누유를방지하기위해내마모성이높은특수합성고무씰을조립한씰부착형(UU)이 있습니다.

씰부착에는양질의리튬비누기그리스 2호가봉입되어있으므로그대로사용할수가있습니다.

씰부착형이아닌경우는스터드또는내륜의급유구멍이없어조립시의초기봉입뿐이며재급유할수없는것도있으므로선정할때는치수표를

잘확인하여야하며재급유가필요한경우는형번을올리는것이바람직합니다.

트랙부하용량

트랙부하용량이라는것은베어링이외륜과접촉하는상대재료가장기

간반복사용에견딜수있는허용하중을말합니다.

치수표에기재되어있는트랙부하용량은 1.24kn/㎟의 인장강도를가

진강을상대재료로할때의수치입니다.

따라서 재표의 경도를 높게 함에 따라서 트랙 부하용량을 크게 할 수

있습니다. 아래의표에상대재료의경도및인장강도에따른트랙부하

용량계수를나타냅니다. 각각의상대재료의부하용량을구할때에는치

수표 중 기재되어 있는 트랙 부하용량 및 상대재료는 전동면 경도

Track Load rating

Track load rating means allowance load which relative materialcontacting with outer race of bearing can endure long�termrepetitive use Track load rating listed in dimension table is avalue when using a steel having � ��kn/mm of tensile strength asrelative material Therefore� track load rating can be increasedaccording to increase hardness of material Below table indicatestrack load rating coefficient according to hardness of relativematerial and tensile strength When calculating load rating ofeach relative material� should multiply track capacity coefficientto track load rating listed in dimension table and HRC �� of racesurface hardness and over ��N/mm� of tensile strength arerecommendable for relative material

Yoke type track roller consists of two lock rings which are fixed to inner & outer races and needle or cage For its material� high carbonchrome bearing steel is mainly used Seal type prevents leaking of lubricant and has anti�dust effect Grease is supplied throughlubrication plate Yoke type track roller is fit to high load� is easy to mount� and has lower price Therefore� it is widely used forconverting rectilinear motion or rotation motion into axial motion NART has two types: cage type being suitable to high speed andfilling type used for low speed & heavy load Lubricating period is different depending on use environment and operating conditionbut in case of filling type� about months are recommended NUTR is a double row needle filling type without cage and ismanufactured into two different types which inner diameter is same and outer diameter is different NUTR is a double row type� isfit for high load� and is designed to impact resistance NUTR_R type has spherical outer race shape and NUTR_SL type has cylindricalouter race shape There is a lock core preventing separation by connecting lock ring which guides outer race and axial direction Thislock core also has anti�dust effect NAST is a separation type bearing which thick inner & outer races and precise cage attaching typeneedle roller are assembled� and due to simple structure� price is low and can calculate locking degree NAST_ZZ has two lateral platesto both sides instead of lock ring� and guides outer race Unlike NART� lateral plate of NAST has a shape to be separated NS producesand sells track roller as three types: OPEN type without lateral plate� ZZ type with lateral plate� and RNAST type without lateral plateand inner race

In case of NS slide bush system� even though using it normally� if using certain period� it can be damaged by rolling fatigue due to anaffection to ball or rolling surface by repetitive stress For rolling surface and ball� they always have an affection of repetitive stressand therefore� flaking is occurred by rolling fatigue Life of ball bush system is defined as total driving distance until the first flakingis occurred to ball or rolling surface

Rated Load and Life

If slid bush system takes severe load or big impact load under stopped or moving status� a permanent strain partially happenedbetween block and rail surface If such permanent strain exceeds elastic limit� it interferes rectilinear motion Therefore� basic staticrated load is generally decided as the limit of static allowable load Basic static rated load means a load having uniformed directionand size which sum of permanent strain of roller and permanent strain of rolling surface becomes � �� time of roller diameter incontact part which is pressured with maximum stress

축및하우징

슬라이드부쉬의성능을충분히발휘시키기위해서는축및하우징

의가공정도가양호해야합니다.

축

슬라이드 부쉬의 경우 축의 표면과 볼이 점접촉을 하여 볼 궤

도면을 형성하기 때문에 축의 치수, 정도, 표면 거칠기, 경도

가 주행 성능을 크게 좌우합니다. 따라서 다음의 사항을 주의

하여 제작해야 합니다.

1) 표면거칠기는 원활한 구름에 중요한 영향을 미치기 때문에

적어도 Rmax 3.2s이하의표면거칠기가필요합니다.

2) 축의 경도는 HRC 60~64가 최적입니다. 경도가 HRC 58미

만이 되면 수명이 저하되고 허용 하중이 감소합니다. 또 경

도가 HRC 64를 초과하면볼의마모가증가합니다.

3) 축을 표면 열처리하는 경우 연마 후 경화층은 1mm 이상이

필요합니다.

4) 틈새조정형및개방형의축은가능한한규격표의내접원경

치수의하한이하로하고상한은피하는것이좋습니다.

Prevention of Foreign MaterialsForeign materials affect bad impact on rectilinear motionsystem and can be the cause for accident and damage Therefore� when installing� should pay attention toprevent foreign materials

Installation of Rail UnitDegreeEach degree is listed in dimension table Combination of open type unit SC�OP and supporting railSBR has general grade and precision grade as below table�and they are selectable

Notes when Installing

Because NS rectilinear motion system is precision part� itsdealing should be careful and pay attention to followings:

Life Calculation


Slide unit

L : 정격수명(km) / fH : 경도계수 / fT : 온도계수

P : 하중(N) / fC : 접속계수 / fw : 하중계수C : 기본동정격하중(N)

Lh : 수명시간(h) / ℓS : 운동거리(m)

L : 정격수명(km)

n1 : 매분왕복횟수(cpm)

Lh : life time (h) / ℓS : motion distance (m)

L : rated life (km)

n1 : stroke number per minute (cpm)

The life of NS slide unit is calculated using following expressions like slide bush

L : rated life (km) / fH : hardness coefficient / fT : temperature coefficient

P : load (N) / fC : contact coefficient / fw : load coefficient

C : basic dynamic rated load (N)
