Very simple motor hook up.

Need a motor hook up to a home project drive? Turn horizontal shaft power to vertical drive and maybe a horizontal propeller for shallow water fun.

Belt drive in heavy agriculture and industrial equipment is certainly well proven and is not expensive and new improvements in belts of all design are available.
Belts absorb shock and vibration and machines can be soft rubber mounted for a more user friendly application.

 

Belts are great , but there limited in HP transmission ability.

Usually 10hp per V belt is about it.

 

Very simple motor hook up

In our Dairy industry everything ran on belt drive,electric motors from small to hundred HP and we rarely every changed belts. We have very big agriculture machines using belt drive.New belt technology has come a long way and I love those Harley belt drives and all the cam belts.Chains fling oil everywhere,gears are noisy.

 

the v-belts have a lot of friction and hence a lot of power loss. One advantage however is the v-belt allow slight slippage and will attenuate any vibration or shaft occilation that could otherwise damage a drive train from damaging harmoics.

A cog belt does not allow slip, but still has some slight damping capabilities, but has much lower power loss. Hence their use on belt driven carts, motor cycles and cam shafts. Neither system however allows you to change the drive by 90 degrees, the axis of the motor is the same as the axis of the driven shaft.

A large belt system for 50 to 100 hp is not inexpensive, almost as much as a chain or gear drive. But they are much lighter than chain or gear, and as you pointed out, they tend to stay clean and do not require lubrication or maintenance other than to occasionally check belt tension.

 

thank`s Petros if you look closely at the image of the power mower with v belts you will see that the horizontal motor shaft output is changed to vertical drive.

 

yes, now I see it, I thought it was set up to drive the back wheels. that is an obsolete installation, it has even more friction than a straight v-belt arrangements. It is also not as compact, it needs length to allow the belt to twist. It wears the belts out pretty fast too. You do not see it used much anymore. It is also prone to throwing a belt, especially if it there is any slack in the belt. It would be okay for a low power installation, but I think the losses would be too large for say a pedal boat that would use a conventional prop.

 

The image is from 1960 and the gentleman driving was a local inventor responsible for many inventions now in use worldwide for instance the Hydrodrive surface propulsion and many others. Rotary motors, aircraft and outboard`s.
Many belts in use have guides and tensioners to stop belt throwing and wear.I is not used much because not many people realize that it can be used successfully. It can not be visualized easily.
You do not need to
turn the vertical shaft to full 90 degree angle but just a small amount. A similar set up would be good for pedal boats and light using aluminum pulleys with good gear ratios even variable gearing.

 

worked on 1000 hp chippers that are belt drive.
