How to measure the radial and axial directions of the diaphragm coupling

Diaphragm couplings are often used in our lives, so how to distinguish and measure the radial and axial of the coupling? The following is the detailed content of the diaphragm coupling brought by the administrator. I hope that each People produce a harvest!.

How to distinguish and measure the radial and axial of the coupling

You want to find the concentricity of the coupling, the coupling has a circular surface and an end surface. 1. Circumferential surface (radial) The dial indicator can be attached to one end of a coupling, any position is possible, and no other things can be touched after one rotation; then the thimble of the dial indicator is placed on the other side of the coupling. On the circumferential surface, the reading of the meter should be an integer of about 3-5 mm, and the meter can be adjusted to an integer. 2. Make a mark on the upper, lower, left, and right of the coupling, turn the dial indicator to these four directions, and make adjustments based on the readings. For example, the upper reading is 3mm and the lower reading is 3.5mm. , Then one side of the coupling with a large reading should be raised up but the other side can be lowered.To be sensitive to use, if it is a motor, it must be raised or lowered.End face——Suck the dial indicator on one end of a coupling. It can be in any position, and it can’t touch other things after one rotation; then put the thimble of the dial indicator on the end face of the other coupling (that is, The side of the coupling), the reading of the meter should be an integer of about 3-5mm, and the meter can be adjusted to an integer.The adjustment method is the same as above.The dial indicator for the end face and the dial indicator for the circumference are generally staggered by 90 degrees. The circumference and end faces are adjusted together so that they will not interfere with each other.The size of the coupling reading should be calculated based on the support point.
To put it plainly, the radial direction is the direction of the diameter. For example, for a shaft, the outer circle direction is the radial direction.The axial direction is the direction of the two ends of the shaft.That's it, now it's familiar enough and easy to understand, ha ha!What you call jitter is the deviation value between the practical scale and the fundamental scale.For example, if you want the outer diameter of your shaft to be 50mm, and then you actually measure other values ​​such as 50.01 or 50.6. This value is more or less than the value of your basic scale is the value of the jitter.There is a benchmark for beating, which is attributed to the azimuth service.The radial direction is generally based on the centerline.The axis is also generally based on the centerline, that's it, I hope to help you again!
The radial direction is simply the direction of the radius, which is the direction of the axis from the axis to the circumference, which is the direction of the axis line.For example, the direction of the spokes is the radial axis and the axial direction.

Selection strategy of diaphragm coupling

According to the JB5513-91 specification, the SWC-I and SWC diaphragm couplings are selected according to the following methods.Please consult our company for the selection of other types of universal joint shafts and negotiate together.

 

According to the JB5513-91 specification, the SWC-I and SWC diaphragm couplings are selected according to the following methods.Please consult our company for the selection of other types of universal joint shafts and negotiate together. 1. The diaphragm coupling should be selected based on load characteristics, calculated torque, bearing life and operating speed. 2.核算转矩由式（1）、式（2）或式（1）、式（3）求出：
Tc=KT............................(1)
T = 9550 Pw   n .........(2 or T=7024 Ph   n ...........(3)
Where: Tc-calculated torque, N·m T-theoretical torque, N·m Pw-driving power, kW Ph-driving power, hp n-operating speed, r/min; K-operating condition coefficient, see below Table 1. Table 1 Operating condition coefficient K

3. Under normal circumstances, the diaphragm coupling is selected according to the transmitted torque and bearing life. It is also possible to check and change only one of the strength or bearing life according to the detailed application requirements of the mechanical equipment. 3.1 Strength check Perform strength check according to formula (4) Tc≤Tn or Tc≤Tf or Tc≤Tp..........................(4) Where: Tc-calculated torque, N·m; Tn-nominal torque, that is, under the given conditions—coupling speed n≈10r/min, axis bending angle β=3o and bearing life LN=5000 hours, the theoretical calculation value under stable load, N·m; Tf- Torque promised according to fatigue strength under alternating load, N·m; Tp- Torque promised according to fatigue strength under pulsating load, N·m; Tp=1.45T 3.2 Check of bearing life Check the bearing life according to formula (5).

Where: LN-use life, hours; n-operating speed, r/min; β-The axis bend angle at the node of the period when chatting in the homework, (o) Tf = fatigue torque, kN·m; K1-prime mover coefficient; Motor: K1=1 Diesel engine: K1=1.2; KL-bearing capacity factor, see Table 2; Lmin-bearing life, hours.

The above is how to distinguish and measure the radial and axial of the coupling. The detailed content of the selection strategy of the diaphragm coupling is not the same as the new content of the administrator of this site. How does the company distinguish and measure the diameter of the coupling? The content of the selection strategy for the axial and the diaphragm couplings can be given a variety of consecutive texts and pictures to prove, compared to any official website with the same content, please respect the boss and friends must be checked by someone to prevent Hit.
