Anonymous users2024-02-04How to measure the internal teeth! Hello, happy to answer your <>
With the help of two measuring rods with appropriate diameters, measure with calipers, and add two measuring rod diameters to the caliper reading, which is the length of the common normal of the internal teeth. The empirical formula for calculating the diameter of the indexing circle of gears is: diameter of the indexing circle = modulus * number of teeth.
Between the top circle of the rental tooth and the root circle of the tooth, a circle with a certain diameter of d is specified as the benchmark for calculating the size of each part of the gear, and this circle is called the indexing circle. Its diameter and radius are represented by d and r, respectively, and the value is only related to the product of the modulus and the number of teeth, and the modulus is the end modulus. Independent of the displacement coefficient.
Extended information: Measurement method of indexing round chord tooth thickness: special measuring instruments are required to measure the indexing round chord tooth thickness, and the tooth top circle must be used as the benchmark when imitating the measurement, and the measurement results are undoubtedly affected by the accuracy of the tooth top circle.
Therefore, for gears with m>10 mm, the method of measuring the length of the common normal is often preferred to test the machining accuracy of the gear. Use the two feet of the micrometer (or precision vernier caliper) to cross the gear K teeth, tangent to the tooth profile at a and b two points, the distance between the two tangent points AB (or AC) is called the common normal length, expressed by WK, the unit is mm (where M is the gear modulus, K is the number of teeth across the gear). I hope I can help you <>
Do you have any other questions?

Observe the tooth profile is straight and the bottom of the tooth groove is wide and the arc is small, it can be preliminarily judged as the diameter control, pressure angle, and can also be compared with the gear hob or standard rack sample to determine which pressure angle is.

Fellow, I really didn't understand, I can be more specific.
There are several methods: 1. Measuring the height of the tooth method 1Measure the full tooth height h (the effect of the arc must be taken into account):
m=h Second, measure the outer diameter of a single gear method 1count how many teeth there are; 2.Measure the outer diameter of the gear, then the modulus m:
m=da (z+2) - This formula is valid for standard spur gears Note:

Positioning measurement method: the tooth-shaped rigid stylus is used to position and measure the position parameters of each gear along all the displacement of the gear teeth, so as to obtain the gear tooth parameters. 2.
Theoretical measurement method: according to the geometric characteristics of the gear teeth, the computer is used to design the gear tooth parameters, and then the gear tooth parameters are calculated by specific software. 3.
Direct measurement method: Optical measuring instrument is used to directly measure the tooth parameters according to the geometric characteristics of the tooth surface. 4.
Laser measurement method: The geometric features of the tooth surface are scanned by laser rays to obtain the tooth parameters. End of this answer!

Can you add, I don't quite understand it.

Let me tell you, I am the champion in this industry, this profession, I personally think that surveying can do the work of the constructor, but the constructor may not be able to do the work of professional surveying, and the measurement technology is stronger. It also depends on whether you want to do the measurement of housing construction, or the measurement of roads and bridges, or the measurement of hydraulic engineering, although they are all measurements, the calculation of the main measurement lofting is almost the same. However, different projects, the construction organization is still slightly different, and the technical requirements are also different As for whether the job is good or not, it depends on the family relationship of the landlord. >>>More

What you mean is that you want to adjust the motor speed by measuring the temperature of the two-speed motor, that is, switching the number of poles of the motor when the motor temperature reaches a certain value. For the motor itself, there is no such function, we need to add auxiliary equipment, such as a control box or PLC composed of relays, which we collectively refer to as the control unit. First of all, we need to set a temperature limit value for the control unit, that is, a switching critical point, when the temperature sensor transmits electrical signals to the control unit to reach the critical point, the control unit performs an operation that was previously changed manually, such as changing the number of poles of the motor as you mentioned. >>>More
