Lets say I have an Electric Gear Drive Motor.
The electric motor is rated at 95% and the gear box is rated for 90% efficiency.
I want to know the final efficiency of the Motor coupled with gearbox.
I think the final efficiency wud be
final efficiency = gear box efficiency * electric motor...
I have a 1/4" seal seated onto a TGP 1/4"shaft. The seal is a double lip with a spring and is pressfit into a housing. we never had any problems with leaking.
But this one assembly that has been assembled is leaking. One or two them, may be a bad piece. But all fifteen out of fifteen are...
do any one know how to take into consideration the pressfit issue when calculating L10 life. I have a situation where the pressfit of our bearings is causing negative clearance. i want to take into consideration this into my L10 life calculation.
I am thinkin of pressfit causing a radial force...
is there anyway i can take into consideration manufacturing defects into calculating L10 life of a bearing.
do any one know if there is any tabulated values of frictional losses in gear mesh. i hope i am not sounding stupid when i am asking this.
I am posed with a problem which i have no clue about. I am testing a gear transfer.
The gears are all Spur at pressure angle of 20°. The gear oscilates back and forth in its axial direction, now if it was radial, that would have made sense to me. The gear is enclosed in a housing. It is...
