When installing bearing on shaft, hit/contact the bearing inner ring. Not the outer ring or it will damage the bearing, specially when it's a tight tolerance fit.
Для тех кому интересно - это планетарноцевочный редуктор… очень эффективная штука при понижении числа оборотов до больших значений в малом корпусе. Минус в сложности изготовлении и частых заклиниваниях…
If the press fit is on the inner, you tap on the inner, if on the outer, tap on the outer otherwise the balls leave dimples on the running surface and you start with a stuffed bearing.
That is 100% wrong. First, the guy above me explained it well, and second these are hardened and wont take any damage from light tapping. The worst that could happen is that if you tap too hard the ring could shatter in thousands of pieces - but definetly not with the tapping shown in the vid
sim, foi muito errado ele bater com um martelo de metal isso vai arranhar e danificar a peça, tem que bater com um martelo de madeira revertido de couro ou emborrachado, martelo de borracha nunca vai arranhar as peças.
Small taps may not he too bad. It's all a case of knowing metal and hardness and what impact will deform. You CAN use a chisel as a screwdriver and visa versa; depends on circumstances!!! PS. I own over a 100 ! .... and respect the difference!
I don't think the few soft taps he gave the bearings would hurt them, though he could have greased the bearings before inserting them. Sure they will get grease eventually, but there can be some significant wear if they run dry under load for any period of time. The majority of wear to your engine bearings occurs in the first 30 seconds of starting your car in the morning.
It’s sad that fewer and fewer people get experience how satisfying this is…rebuilding a transmission, steering gear, etc. with cleaned parts and new gaskets and seals.
Not an excellent job! Looks like a job of a novice. should have packed both bearings with grease before mounting them. Pounding metal to metal is another no no!
I've rebuilt several of these units part of a centrifuge/strainer equipment. They have a grease line on the bottom. When the grease line brakes they don't last very long.
@@roaringcat1 Come on man, you use a bushing that is the same diameter as the inner race of the bearing, to lightly tap against. Never ever hit the outer race unless you like redoing your work in the not too distant future.
NLG 1 grease or 00 imo ,not very common to see since most parts use the type 2 but I see the mechanism there might require a constant lubrication flow grease tho
Если нужно забить подшипник, то используй трубку того же диаметра, что и внутреннее кольцо подшипника. Технология провкренная временем. Трубка гораздо более мягкая, чем подшипник
It's a sumitomo cyclo gear box not a auto transmission. It achieves incredibly low gear ratios the part he is striking in isn't damaged I've assembled hundreds of these.
Everything was fine until he hammered on the outer race. Contrary to popular belief, you can use a hammer to seat a bearing. However, you must ONLY hammer on the race making contact. If you are seating it into a flange, you hammer the outer race; on a shaft, hammer the inner race. It’s intuitive once you understand.
