7.5 KW 1440 RPM Wood Splitter with 80mm Drill & 1050mm Belts: Techniques to Prevent Blockages

Question

Hello, I have a splitter like in the picture. 7.5 kw engine, 1440 revolutions, drill fi 80, drive for belts 17 two pieces length 1050, belt pulley on the engine external dimension 80 and shaft on the shaft fi 170. The problem is that the drill comes into a tree and blocks . The belts slide on...

tata1 · Answer

From the photo you can see that you have too small a pulley on the engine. From here the straps catch the slip.

Just a small pulley has too small a contact area to the belt and hence a slip.

Of course, the wheel on the auger must also be bigger then.

Insert the image of the drill bit at the side, look also at the angles of the belt grooves and the belt or the belt is not too shallow in the grooves.
A good solution for the small wheel on the engine is the toothed belt.
A pulley on a steel or cast iron engine?

piotruś 123 · Answer

the wheel is steel.

My log splitter has a 300mm shaft on the 150mm engine, 4kw engine, 900 rpm, 2 V-belts 17. The roller speed is about 450 revolutions. Strips tensioned on the string, sometimes as it hits the knot also becomes but the engine. I have a switch on hand so I switch it off quickly.

I would put a circle on the drill again, it would be slower to spin, and it would be "stronger".
I do not know if I counted correctly, but the borer rotates at 677,6 revolutions per minute, for which he has such a turnover, it will be enough for 400-450, recommended from 400 to 600.

1 PAWEL · Answer

The steel wheel is not recommended, the cast iron is better, the straps are well laid out to the depth.
Check again if the straps adhere well to the sides of the belt grooves and try to degrease the surfaces of the grooves and the belt.
Colleagues are good at replacing wheels.
Enlarges the wheel on the engine and the wheels on the auger spindle.
You currently have around 677,6 rpm without load.
Certainly it would be enough for around 400 - 500 rpm.

Rezystor240 · Answer

Use a larger pulley on the auger, torque will increase.
You could use a flywheel on a drill and not stuck on a gnarled tree.
You can reduce the drill itself, you would slower it, but it would not stutter.

Wawrzyniec · Answer

Simple, you have too small pulleys, and therefore too small belt. You also have a bad transmission and too high a turn of the bit, so it can also wedge. I also have a borer 80, and the pulleys are: on a 100mm motor, 2x17 a on a 300mm borer. At 270 it would also be fine and a little faster. I have never blocked the bit, and I also crush the gnarled and twisted. Recently, I was cutting an apple tree 50cm in diameter and 40cm in height and birch, the same blocks. The engine warmed up a little, and I have 5.5kW of 1,440 revolutions.

piotruś 123 · Answer

I will start by replacing the toothed belts. If it does not help, I'll put a circle on the 270 drill.

piotruś 123 · Answer

Łupiarka repaired. I put on the toothed V-belts and set the engine well on the strings so that the belts fit well into the engine belt pulley. The smoke goes out with the drill . Thank you for your help. If someone wants to buy a tree saw, I invite you to my olx auctions. Gives the ID of the ad: 284505359

1 PAWEL · Answer

Toothed belts are the best output for smaller pulleys, they are much better around the wheel than ordinary V-belts which are too stiff.

Wawrzyniec · Answer

There is one more thing about this splitter: an incorrect switch, not the motor. You have this:

With such an engine

And you should have one

Added after 45 [seconds]:

and for a current greater than 20A. With this connection you have now overheated the engine.

piotruś 123 · Answer

But then it is not left - right. And if it's jammed, it's a problem. And so the rotation to the left and wykręcam.A engine is connected in a can at once and is ok.

Wawrzyniec · Answer

Did you check it? Probably not. And if you come to crush gnarled wood, you will burn the engine, or the switch, or the installation at home, because such a connected motor generates high currents, you have a clear sign, you see. This is a connection to start-up, not work. If it fits well, there is no chance to unscrew the engine, and besides, this engine in this connection has a much lower power with a higher power consumption and does not keep the rotation. I saw once the switch right / left / star / triangle.

kortyleski · Answer

What are you saying, Wawrzyniec, for nonsense? According to a readable plate, it should be associated in a star. Only switching into a triangle will cause the flow of high currents, but only briefly because the engine will burn.

Wawrzyniec · Answer

This is probably a spring eclipse. From the morning I would split a tree, cut into blocks and plunder again.
