Re: Motor Spring Question
Since the inner "hole" is exactly the same as the outer one, it's just another way of saying "pear shaped"!poodling around wrote:I know what the outer end 'pear shaped' description means but what is the inner end 'hole' connection ?

So ......... both ends of the spring (inner and outer) attach themselves using a pear shaped 'hole'.
Thanks very much Barry.

What do you think the word " hole " means ?? look in a dictionary if you are unsure !!poodling around wrote:I know what the outer end 'pear shaped' description means but what is the inner end 'hole' connection ?

OK To be fair , there are basically two ways in which the inner end of a spring is attached to its arbor -- either by a pin or stud fitted into
the arbor that engages into a hole drilled in the spring , or some springs have a shaped inner coil without any hole drilled -- those springs engage to a shaped hub or cam , the spring having a correspondingly shaped end. Those are known as hub fittings. To be correct , not all inner end holes are pear - shaped (although most are ), the exact hole profile can vary between manufacturers -- some are just oblong slots .
Better still , why don't you buy up a few old gramophone motors -- they don't cost much -- and educate yourself ??
As I was told 50 years ago -- you can read as many books as you like and ask as many people as you like , but ultimately the only way to gain accurate knowledge is to have a hands on approach and learn yourself !
