hahayanyan hing,

hahayanyan師兄，
我净係攪過支軸，轉過用好薄既油，换過thrust bearing......
等我放假時再攪吓先
Thx

分享下你多一些的drifting 狀況

你搞過啲乜嘢改善, and 有啲乜嘢 可能應該要攪蛋 未搞呢

Let's see.. If we can troubleshoot together.. And some other c hing may have some skill to share too

Drifting... 例如曾經轉33.7號平均冇問題 for a few minutes .... 突然間唔知點解去到34點5.... 平均,

但係又不然間轉去三十二點三又一段時間...?



Drifting around 33.3 +/- 2% level?

Remember.. Quality Table at that period.. 0.1..0.2 % should be very easy to archieve.. Etc.. .

U Shall be fine after more effort..

No harm to double check your line voltage stability too

就係301盤，speed drifting .........攪到人都癫

有快有慢 範圍 去到什麼程度?

如果你講緊冇需要speed control 嘅唱盤

佢嘅快慢範圍其實都好窄.. Some very very old table.. May be +/- 2%

Thzoe Garrard 401...lenco.. Etc.. 大部分都喺+/- 0.X% 一個小數位後的% 甚至更低 from 33.3 reference speed

As 50 hz is fairly stable...

如果你碰上一個 用這些AC 同步馬達... Always plus or minus around 37rpm, or 31rpm...

呢一個應該係其他物理上嘅 問題.. Not the motor issue.. Etc..


For example.. Garrard type.. Or other belt driven... 可能係皮帶或idler lose grip

If it is lenco.. Idler and 雪糕筒的接觸點錯誤 etc..


其實嗰啲motor 去到401 嗰個年代已經可以做到 0.1% accuracy...


Etc..


Haha

hahayanyan師兄，
有無試過個盤，無俾speed control都會時快時慢？？
Thx

Life is full of fun.. If we create some

We all have mistake and moment of weakness.. Lets goes and forgive ourself.. And get some rest.. And start again..


Take care

Wait for your good 401 and 75 video


Haha

多謝Haha
讓一切回到正常,去勇於接受生命/生活的轉變/改動。

Hey..cobra

有一件事情一定是對的..

Simple. Rule.. Make today not bad
. Or ok.. Tomorrow more chances to be better.. As long as we may understand or have a habit what is the right things to do today...

明天 一定可以會更好

Add oil


Good luck and take care


Toy later..or now if some toy may make tomorrow better.. Then toy now.. Or later..

闊別接近2個月,再次按入來看看 ..............

看到HaHa兄的呼喚.............真的百感交集。

新年過後,心情一直低落,3月頭再出現一些問題,捱到上週終於爆煲,事後檢討這兩個月,不斷關注自己無法改變的東西,投入到自己控制不了 .........

希望事情告一段落,聽太太的勸告,未來的事將來去面對,再想都浪費時間,
我希望做到~活在當下。

昨晚試左3種油, free rotating 都係十秒左右, 但wow有改善的
用33rpm試

1/ 衣車油 0.31
2/ 衣車油+ graese 0.36
3/ 3號油 0.21 (oil最thin)

最後都係用3號油

仲有個grease盤未試....

ThX, haha師兄

haha i do not know...hows the CTC build, and they may have more than 1 bearing for 401/301 too...

they shoud tell u at their oil bottle ?(come with the CTC.. sometime they tell how many drop..or how many CC , and u may not have it..as u said..it come with the table


cannot find those "bottle" photo from CTC yet

does it have a Felt washer?

open that bearing.... never assume there is nothing missing........... usually from the bottom haha

if u do not find how much oil...for that CTC... send them a message at the facebook page..

or keep drop by drop adding until u see oil start coming out from the top gap



最後修改時間: 2022-03-22 13:26:05

hi 師兄，
我買返來已經係CTC bearing 了，油有無話入幾多？？

Thx

this is how the the bearing look like

lets say...if there is no external object / big dust..etc..inside the cavity ..

u may feel a little bit of friction in between " felt ring washer" and the shaft

if u feel quite a bit of friction...check..if that "Felt" are dry and hard ? it suppose to be soft and filled with some oil

also check the condition of the bottom brozne thrust pad.. to see if it is in very poor surface condition and clean it..etc..

enough oil ? nothing damaged or deformed...every things straight..etc?

if nothing deform and felt is soft and oiled...and enough oil ..etc... if u still feel uncomfortable about the "high住咁"... u may need to upgrade to some 3rd party bearing etc..
