Gears are a common bite device. Many parts have gears. Without gears, many equipments cannot be deployed smoothly. There are some parameters for reference in the use of gears, which have an impact on the development of our gear work. The gear coefficient is a very important indicator. Now let's understand what the major coefficients mean. I hope our introduction will be helpful to everyone. As a reliable gear manufacturer, our gear processing experience is still relatively rich, and provide a variety of gears, let's take a look! Use factor KA: It is a factor that considers the influence of additional dynamic load caused by external factors when the gear is engaged. This dynamic load depends on the characteristics of the prime mover and driven machine, mass ratio, coupling type and operating state. Dynamic load coefficient KV: It is a coefficient that considers the influence of the dynamic load generated when the gear itself meshes and transmits. Related to manufacturing and assembly errors, peripheral speed, etc. Inter-tooth load distribution coefficient Kα: It is a coefficient considering the influence of uneven...
copper sleeve has good process performance. The processing and manufacturing process of the working parts of the die is generally more complicated. Therefore, it must have adaptability to various processing techniques, such as forgeability, machinability, hardenability, hardenability, quenching crack sensitivity and grinding workability. Precautions for the processing of copper sleeves: Every process in the manufacture of copper sleeves must be thoroughly cleaned, so that the residues left in the pore solution affect the following method. Due to silver, mottling that prevents this phenomenon sometimes produces an appearance that affects the quality of the coating. When using the pre-coating process, their components must always hang and swing left and right together to achieve the same effect to achieve a uniform coating color. According to the stamping process and the type of raw materials, softening treatment and surface treatment can be arranged if necessary, and the appropriate lubricant and lubrication process can be selected. While considering the improvement of the material judgment and utilization, the unreasonable reciprocating feeding layout method and the too small overlap value will often cause the sharp wear...
Choose different copper bushings according to the application environment of copper bushings. Copper bushings are generally used for bimetals, etc. For example, automotive bearings, so we have to choose copper bushings with good wear resistance and corrosion resistance. The focus of the steel casting industry is high temperature, because of the particularity and inevitability of the industry, it is indispensable to deal with various high temperature environments in daily work, which makes some equipment always in a dangerous environment. Many industries now use electricity as energy to provide power, and electricity can only be conducted through cables. Its normal working temperature is much lower than the temperature in the steel casting environment. At this time, we need to take a protective measure for the line. To ensure its normal operation. Therefore, the same material sleeve corresponding to the wire specification should be used when selecting. When selecting a protective sleeve, first select a part of the sample and make a test. First observe the color of the glass fiber inside, which is generally white, and there are also milky white...
Gears are a common part in our lives. Gears on the market are large and small, they are widely used, and there are many types. It can be said that in different mechanical equipment, the gear chamber is a very important part. In operation, although the gear may be small, the responsibility it bears is very large. The shift gear is a relatively rare gear. Modified gears refer to gears with indexed circular teeth whose thickness is not equal to the width of the tooth groove and gears whose tip height is not the standard value. The gear whose centerline of the rack tool is not tangent to the index circle of the gear to be processed is called a modified gear. The amount of displacement in the modified gear refers to the vertical distance that the center line of the tool translates from the position where the standard gear is processed. The displacement coefficient refers to the coefficient required to express the displacement with a standard modulus. The small displacement coefficient of the modified gear top refers to the...
Gears are big and small. Whether it is large mechanical equipment or small precision equipment, gears can be seen everywhere. It can be said that the operation of these equipments is inseparable from the use of gears. Gears are very important transmission devices, especially precision gears. Here's how to realize the transmission of precision gears. 1. Forging blanks. Hot die forging is still a rough forging process widely used in gear processing. This technology is suitable for relatively complex stepped shaft blanks. It not only has high precision, small post-processing allowance, but also high production efficiency. 2. Normalizing. The purpose of this process is to obtain hardness suitable for subsequent gear cutting and final heat treatment for tissue preparation to effectively reduce heat treatment deformation. Practice has proved that the use of isothermal normalization effectively changes the disadvantages of normal normalization, and the product quality is stable and reliable. 3. Turning. In order to meet the positioning requirements of high-precision gear processing, the CNC blanks are all used for the processing of the tooth blanks, and the mechanical clamping is...
With the rotation of time gears, China's industry is becoming more and more developed, and industrial equipment is gradually updated, but from the beginning to the end, there is no missing part, that is the gear mentioned at the beginning. You should all know the role of gears, which are widely used. It ranges from daily necessities such as clocks, automobiles, sewing machines, CD players, to industrial equipment such as food processing machines and machine tools. Everyone knows the role now, and the processing method of the gear is very important. The following describes two kinds of gear machining methods. 1. Profiling. The gear machining tool cuts the tooth groove of the gear, and the "cross-sectional shape" of the tool is the shape of the gear tooth groove. When the gear is processed, there is no gear meshing motion, and the precision of the processed gear is low, and the general accuracy is below 11 grades. 2. Fan Cheng processing. The gear cutting tool itself is a "gear or rack", and a gear hob can be "thought" as a rack...
