I have an Aspire York treadmill. when i switch it on and start the machine the belt increases in speed to the maximum speed even though i haven’t touched the display. Also when i try to decrease the speed via the display the belt just keeps on running at full speed! Can anyone tell me how to fix this please?
Experienced athletes share their insights in answering this question:
Yes. Replace the speed sensor. In the unlikely event that the problem still is not solved replace the circuit board. J.
How to Identify and Resolve Common Issues ?
We offer a diverse range of insights on identifying and resolving common problems in sports. Our sources encompass academic articles, blog posts, and personal essays shared by seasoned athletes. :
Maximum power as a function of speed
To reach this maximum, the belt speed must be set to the optimum. This is also called optimum belt speed and in the present case is about 50 m/s and corresponds to a rotational speed of the smaller pulley of 4774 min–1.
The V-belt acts as a transmission belt. Connecting the V-belt pulleys, it transmits the force from the engine to the ancillary components including the alternator, the hydraulic pump for the power steering.
Belt surface speed should not exceed 5500 feet per minute (28 m/s) for larger pitch belts and 10000 feet per minute (50 m/s) for minipitch belts.
This is just the rigid outer belt.
The Speed Belt features internal MOLLE pass-throughs, unlike the external MOLLE found on most modern belts. This design keeps your pouches tighter to your body and more stable while also preventing the pouches from sagging.
To speed up a drive, you can either make the Driver larger or the Driven smaller. Either is acceptable. Since changes to your pulley sizes proportionately effect the speed, you can easily determine the needed sizes of the new pulleys.
The speed of a conveyor belt can be measured simply by using a tachometer to measure the rotation speed of the moving belt by measuring planar velocity, or directly via the conveyor belt shaft.
The belts are looped over pulleys attached to the driver and follower shafts. The pulleys are placed at a measured distance to create tension on the belt. The friction causes the belt to grip the pulley when in operation.
The belt drive mechanism is a rotation transmitting mechanism for transmission of rotational drive force. The belt drive mechanism includes, for example, a drive pulley, a driven pulley, and an endless belt wound between the drive pulley and the driven pulley.
The maximum circumferential speed of 1000 m/s seems to be a quite general material limit. In the same way as turbines, 0.5 mm steel balls explode if they rotate more than 700,000 times a second, which corresponds to a circumferential speed of about 1000 m/s.
A belt frequency is a rate at which a belt completes a full complete cycle of its length. In other words, it`s a measure of the time it takes to travel the full length of the belt.
Pulleys of Different or Same Size
If a smaller pulley turns a larger one, the larger one will turn slower, but with more power available at the shaft. If a bigger pulley turns a smaller one, the smaller one will turn much faster than the bigger one but with less power available at the shaft.
A worn timing belt will affect your engine`s starting speed as it is attached to the pulleys that drive the crankshaft. Eventually, the belt can slip on the camshaft drive causing the engine cylinder to open and close at the wrong time.
Belts: A belt decreases speed in proportion to the diameters of its pulleys or sheaves. The pulley on a motor shaft is typically smaller than the one on the machine shaft. The speed ratio is R = DL /DS, where DL = diameter of large pulley, and DS = diameter of small pulley.
Flat belts can be used according to belt type for max. speeds of 80-100 m/s. The disadvantage, however, is lower transmitted power, greater width, and the need for higher tension force.
V-belts are designed for optimum performance at speeds of around 20 m/s.
The primary purpose of belt drives is to transmit power from one shaft to another with the help of a thin inextensible band that runs over two pulleys. These pulleys can rotate at the same or different speeds. The mechanical power or rotary motion is transmitted from the driving pulley to the driven pulley.
Belt-Pulley is like Chains and gears that transmit power from one shaft to another shaft that uses belts and ropes when the distance between the two shafts is large.
How do v-pulleys work? The V-shaped grooves on the belt hold on to the V-belt to avoid slippage. The tension of the belt, combined with the friction of the grooves against the belt cause the pulley and shaft to rotate together.
A belt-driven actuator converts rotary motion to linear motion by means of a timing belt connected between two pulleys at either end of the drive.
Definition. Vr is defined as the speed at which the rotation of the aircraft should be initiated to takeoff attitude. Rotation speed (Vr) cannot be less than V1.
: a belt of V-shaped cross section engaging a V-shaped groove in a pulley for wedging and better traction.
V-belts get their name from their trapezoidal shape, which helps them wedge into the sheaves. Twisted synthetic fibrous tensile chords, compressed by synthetic rubber form a typical V-belt, rendering it strength and flexibility.

I have a 99 yamaha f100 four stroke outboard. Problem I have is boat will acclereate fine get up on plane and after running for about a mob at wot will decell and only run around 4500 rpm. Then after coming back to idle will have a slight miss then run smooth and repeat every run. Changed the plugs and fuel filters alll oe yamaha has fresh oil timing belt is good any ideas will help or fuel psi spec. I am an ase master automotive tech so I know alot about engs. To me it feels like it’s running out of gas. Like the carb bows are full when I take off but then runs out after running wot. Any info will help

I have an 8100 ES Reebok treadmill. There is a squeaking noise coming from the drive motor. It is coming from the non-belt side (if facing the front of the treadmill, the left of the drive motor. When the treadmill is turned off, I can manually move the walking belt in the walking / running direction and it will squeak. If I move it in the opposite direction, manually it does not squeak. Also, if I need to lubricate the bearings can you tell me how to get to them to do this. The motor has plenty of power and no other problems, only squeaking. I have sprayed a belt lubricant on the belt and also blown it all out with a can of compressed air (used for computer key boards).
ANSWER : Hi.the bearings in these machines should be lubricated and sealed for life. they are not designed to be touched. it sounds like you have done the important bits. belt lubrication and blowing out any debris that may be there. squeaks like this can be incredibly difficult to find, but can also be incredibly annoying.the main things that you can do is keep watching to try and find exactly where the squeak is coming from and check for anything wrapped around the edge of the roller.keep using the belt spray, and the compessed air.a good grade silicone lubricating spray used at the edges of the rollers, by the bearings and around the motor and gearbox unit may also help but do not get this spray on the belt as it can be very slippery.squeaks like this can start and stop on their own or develop slowly and go just as slowly.keep doing the maintenance you are doing, and use the silicone spray as described above.it may take a little while for the spray to work its way into the bearings as they are fairly well sealed but you should notice an improvement after a few days.please feel free to ask for further advice if you need

I have a Kohler Condidant 5 Generator that will run as long as you hold the start button in. It dies when you let off. I have a harness for the remote switch but no switch – It also will start the generator when you cross the red and black wire and run as long as you hold them together. There are 3 wires to the main switch and 5 to the remote switch. Does the starter stay engaged the whole time you hold the start switch or does the computer release the starter once it is running? The Generator is producing electricity because I tested it while holding the start button. Some where is a wire that shold tell it to keep running. I have read online many descriptions of the same problem, most are told the board is bad so they replace it and still have the problem. Have not found a solution. Talked to a marine machanic today and he said he fixed his friends generator doing the same thing by running a bypass wire but he couldnt remember exactly what he did it was a long time ago. Can anyone help me. Thank you
ANSWER : The problem is either the ballast resistor or the starter bypass relay. The bypass relay should be part of the starter solenoid. I’m afraid I can’t tell you exactly where the ballast resistor is located. It should be a physically fairly large resistor made of ceramic. It should be retangular roughly 1.5″-3″ long and 3/8″-1/2″ accross with a wire on each end. It could also be a coil of wire mounted on a phenolic board.

My Reebok Edge 2.2 treadmill belt keeps sticking at high speed.
the belt rotates just fine when no one is walking / running….
ANSWER : HI preety_p_pat,It seems that it’s time for the belt replacement , and / or lubrication of the belt , it has not been lubricated well.Also if the tension setting has been has been changed by use then you need to reset it as per your convenience.You can do this by adjusting the tension on the belt by using the screws of the front and the rear rollers to get the proper tension on the belt till the treadmill works fine even at high speed.After this works you need to lubricate the treadmill belt by a treadmill belt lubricant available in the market to increase it’s life.Hope this helps …:)
