Question MCP4 problem

I have a slack in the shaft, this motor has only been used in tests without load, when I buy it did not notice and the other motor that is not used does not have that movement either, is it normal or will there be more movement?

And why did not he do it again? Until it is not used a little does not fit and starts to move?

And this is normal too? Has begun to do so by doing a few seconds load test.

It is a well balanced movement seat, you can move with your hands without effort, I probe it directly to the battery for a few seconds, I do not understand that something has broken, will not be adapting the gears? Where it makes noise does not have the shaft play, otherwise it works well

Edit: Running direct to 12v do not make any strange noise, how can it be?

This is the other engine that I have not used with load, only emptiness with smc3, also makes some noise but much less, so weak are the mcp4?

I made another video, the free game is normal but that metallic noise? Every bump there is that dreadful noise

@noorbeast I have been told this from the company that sold me the engines, this means that it can not be used for change of direction? This seems strange to me and I think it is an excuse not to take over the guarantee


Hello,


It seems you may have broken teeth on the gear wheel, This could have been caused when you have been turning the gearbox from the output shaft.


Worm gearboxes should NEVER be back-driven as due to the angular forces applied on the teeth, there is a good chance you will damage them permanently by chipping the teeth off.


I hope this helps, if there is anything else we can assist you with please don’t hesitate to ask.


Best regards,

It is a Seat move design, it is well adjusted the weight and without motors you could move me with two fingers, when the motor moves the gearbox does not make the noise of the video, it is only with the hand, perhaps it is not going so smooth the motor Like the other but it goes well, I only notice that the rapid changes of direction have a metallic sound stronger than the other motor, you have that noise in yours? The noise of the last video I've put.
Before you open the box you want to try to take care of the warranty, if I have to open it as I do? The screws are round inside and you can not use a wrench.

@noorbeast This is the other engine that at first did not have free play, a few days later I stayed with this game, I see it bigger than the other engine, it enters the normal? I have seen that one of its engines had problems of much free play, that had solution without changing the mcp4?

I hate to be rude, but @evolaco what are you expecting from @noorbeast. It's obvious you have problems with your motors gearbox - this is an issue between you and your supplier, or how you have designed/built/handled your rig. - not @noorbeast. - Badgering him with this same line of questioning is not going to change this. Remember to be polite, as no one here is doing this as a job and can chose at any time to answer, or not answer your questions.

@SeatTime That is not the engine that made the noise to gears, the noise motor has half of free play and it continues to run smoothly and no noise while the engine moves the gears, only heard when I move it with the hand and maybe it is normal , I do not know. My dealer, as I have already put in this post, says that it should not be used in changes of meaning so it has made me understand that it will not change anything in guarantee ...

@noorbeast

This is my design, I do not have space to put the engines behind but I think for this design and well balanced should be enough, the balance is perfect, they are just moving a little I notice the free play of the engine, put the balance out so that I did not notice the engines would be forced and it would be worse I think.
As I said this engine is not the one that made the noise and the free game came out to little use, maybe some boxes have a game bigger than others or is a problem like the one you tube in this video, but it is not as big as the yours. Did your video have a solution or did you change the box?

hallo,
did you solved your problem? if yes how?

Hello, I have disassembled the boxes and I can tell you that the gears have a minimum free play, in one of the boxes had game on the same axis and another point that gives a lot of play are the acolples, do not fit perfect or little by little making bigger and gives free play, I'm going to put other couplings like these even if the engine is separated from the box
