Q:How do you calculate the speed of the pulley?
1400 goes to 500, you just have to slow down by 1, 400/500 = 2.8. If it's a belt machine, it only needs a belt wheel with a diameter of 2.8. Other people choose according to the actual situation. If it is a gear, the diameter of the circle is 2.8! But it's generally recommended that you use a pulley, which is easier
Q:What are the coordinates of the shaft and the bearing, and the shaft and the pulley
Axis and pulley: Motor shaft and the pulley clearance fit, and then add the positioning of the key, if is excessive, the motor shaft heat expansion going up bad pulley, so want to have a gap!
Q:What do you mean by SPB SPC
It is. Pulley pitch diameter is pulley diameter section line theory, a bit like gear pitch circle diameter. Generally expressed in PD, cylindrical generally expressed in OD. Different type slot pitch circle and cylindrical conversion formula is different, generally we tend to measure to the pulley cylindrical, in according to the formula to calculate the pitch circle. SPZ: OD = PD + 4; SPA: OD = PD + 5.5; .spb: OD = PD + 7; SPC: OD = PD + 9.6. The minimum diameter of A or SPA is 80mm, if it is less than that, especially at high speed, the belt is prone to cracks and cracks in the bottom. The SPZ band, the small wheel is not less than 63mm. Also pay attention to the belt mounting technique and the tension, too small and easy to slip, too big to damage the belt and bearing
Q:What happens when the pulley becomes smaller and smaller
The same proportion is reduced, the output speed will not change, it will increase the bending of the belt and reduce the life of the belt. It reduces the load capacity, the reduction of the amount of computation, because the belt is driven by friction, the pulley decreases, and the friction surface decreases.
Q:How do you break the pulley of a cygnet machine?
Use a screwdriver to insert a 13mm casing counterclockwise.I hope my answer will help you.
Q:Do you want to change the belt in the machine quickly or quickly?
For example, a big tire is going to go a lot farther than a little tire! So the belt wheel must be turning faster than a small pulley!
Q:What tools do you use for the pulley
See if your motor shaft is directly connected to the pulley, which is more difficult to disassemble. Just knock it off slowly. But if the pulley is taper hole, and the motor shaft taper sleeve connection, that is more convenient, only need inner hexagon spanner remove the screw securing the taper sleeve, lightly, can realize disassembly
Q:You want to increase the speed of the motor, the size of the pulley
Motor pulley should choose between 170 mm to 200 mm, changed after motor power constant, only the torque changed, speak is small enough strength (popular), of course choose power matching the motor,
Q:The crankshaft pulley lock thread adopts the advantage and disadvantage of the left spin
Crank pulley locking screw with sinistral because the engine crankshaft is clockwise (look for the pulley) rotating, after starting the engine crankshaft rotation direction is just the direction of the force after the lock nut and tighten, thus more conducive to prevent the nut loose, it is need to structure design, there is no advantages and disadvantages, otherwise additional strengthening locking measures.
Q:Diesel engine drives the scale of the motor belt
Usually the rated speed of the generator is 1500 revolutions per minute, The speed ratio relationship is as follows: Diesel engine speed A/generator speed B = power generator with diameter C/diesel and pulley diameter D, That is to say, according to the data provided by the now you, you of the diesel engine under the condition of the 2040 r/min matching is normal, the speed is the same as the common diesel engine rotating speed on the market, general quality estimate your generator.
