What is the relationship between the life of the elastic coupling and it?

elasticityCouplingThe heating temperature is one of the important process parameters of the heat treatment process.The selection and control of heating temperature is the main problem of heat treatment quality.The heating temperature varies with the treatment of metal materials and the purpose of heat treatment, but usually heating above the phase transition temperature can obtain a higher structure.In addition, due to the time required for the transformation, when the surface of the metal workpiece reaches the required heating temperature, the temperature is maintained at this temperature, so that the internal and external temperatures are consistent, and the microstructure is changed.This period of time is called the hold time.When using density heating and surface heat treatment, the heating speed is very fast and there is generally no holding time, but the holding time of chemical heat treatment is often longer.

In addition to the economy, WanxiangCouplingThe repair also has its own technology, which requires maintenance personnel to fully understand the corresponding technical requirements of the bearing, as well as the structure, process and material characteristics of the bearing and its components, otherwise it will be difficult for the bearing repair to achieve the expected results.Our factory produces diaphragm couplings.The main material factors that affect the service life of high-carbon chromium steel rolling bearing parts and the degree of control are as follows: ".

1.对于淬火后的GCr 15钢，应获得平均碳含量约为0.55%、Ar约为9%、不溶性碳化物为7%左右的隐晶马氏体的显微组织，淬火温度和时间可控制组织。

2. The carbides in the original structure of the steel before quenching need to be refined and dispersed, which can be achieved by high-temperature austenitization at 630°C, 420°C, or the forging and rolling waste heat annealing process.Our factory produces plum blossom couplings.

elasticityCouplingAn elastic compound containing pre-tightened rubber can provide additional strength and prolong service life.CouplingCan accommodate various deviations.The wheel hub material is aluminum alloy, which is both light and light.Rubber is mainly used for shock absorption, so that the power transmission is stable and quiet, thereby protecting the driving force and driving the machine.

Parallel groove elastic couplings usually have 3≤5 grooves to deal with the problem of low torque stiffness.

The parallel groove type takes into account that the groove is short and does not weaken the ability to correct the deviation, while the short groove can enhance and overlapCouplingThe torque stiffness, which can withstand considerable torque.This performance makes it suitable for light-duty applications.For example, the connection between the servo motor and the ball screw.However, as the groove diameter increases, the load on the bearing will increase, but in most cases, it can protect the bearing.Increasing the size means increasing the ability to withstand eccentricity.

The tooth surfaces of the two half couplings in contact with the reed are curved.When the transmission torque increases, the spring deforms along the tooth surface, so that the force points of the two half couplings on the spring are close.The change of the contact point between the reed and the tooth surface, that is, the torque changes with the size of the transmission torque, and its transmission characteristics are variable stiffness.Therefore, it can withstand changes in load than general elastic couplings.
