The application of plum blossom coupling and the effect of elastic pin gear coupling

The plum blossom coupling is mainly composed of two convex teeth that are closely meshed and subjected to radial compression to transmit torque. When the two axes are relatively offset, the elastic element undergoes corresponding elastic deformation, which plays a role of automatic compensation.

The advantages of plum coupling and coupling: small radial dimension, simple structure.Light weight, small moment of inertia, suitable for medium occasions.

The plum blossom coupling is a widely used coupling, also called a claw coupling, which is composed of two metal claw discs and an elastic body.The two metal claws are generally made of No. 45 steel, but aluminum alloy is also useful when the load is required to be easy to use.

The plum coupling is processed by machining methods such as turning, milling, and broaching, and then undergoes overall heat treatment.With sufficient mechanical strength, there is also a kind of claw plate on the market that is a casting, which can be produced in large quantities and avoids processing losses.So the price is much lower than machining. But the performance of castings is not very good.It is better not to use it in some important occasions.And the claws of the casting are prone to tooth punching (claws falling off) under high load or high load.

The main structural forms of plum coupling are: basic type, single flange type, double flange type, split brake wheel type, and integral brake wheel type.

The quincunx-shaped elastic coupling is composed of two half-couplings with the same shape of the claws and elastic elements. The quincunx-shaped elastic element is placed between the two halves of the coupling claws to realize the coupling of the two halves. Join.

梅花形弹性联轴器主要适用于起动频繁、正反转、中、中等扭矩和要求高性的工作场合，例如：冶金、矿山、石油、化工、起重、运输、轻工、纺织、水泵、风机等。工作环境温度∶–35℃～80℃，传递公称扭矩25～12500Nm，许用转速1500～15300r/min。

The use effect and function of elastic pin gear coupling:

(1) The important thing is to reduce the damage to the machinery and equipment during the working process, to reduce the additional load between the parts and the machinery, to play an important protection and compensation effect, and to bring a good experience in the application process .

(2) The coupling can achieve a relatively stable and stable use effect during the working process. Due to its mechanical strength and hardness, it can avoid various damages.

(3) Since the coupling has a good cushioning effect, there will be no quality problems in the process of various temperature and environmental changes, and it can also have a good role in promoting mobility.

(4) As long as it can be used correctly, there will be almost no problems, and it can achieve a long service life without maintenance and maintenance, so the process of use will be more worry-free, and its specific advantages can also be exerted. .

(5) Since all kinds of mechanical equipment can be imaged with high requirements, the coupling can exert such advantages in the process of working, and meet the requirements of various industrial environments.

(6) The produced coupling can not only achieve relatively stable functionality, but also can achieve a relatively good standard of stability, and can achieve load changes in various environmental applications.

(7) The shock absorption effect can indeed be achieved, and the stability requirements of various components can be achieved. Any problems will not occur during the operation of the prime mover, and the protection and compensation effect of mechanical equipment is also good.

(8) The coupling has the mobility, and can have good compensation ability, can reduce the error in the process of manufacturing and installation, and can well adapt to the changes of factors in various environments.

In the industrial area, I believe that everyone should be familiar with the elastic pin gear coupling. It is widely used in various mechanical equipment. It can be processed and produced with good compensation and protection, and can be standardized to a large extent. And standardization, to avoid damage to various machinery and equipment, choosing the appropriate specifications and models can give play to good advantages and functions, meet everyone's various requirements for production and processing, and give play to multiple performance uses.

The offset compensation of the elastic pin gear coupling caused by the installation deviation or the deformation undertaken can be corrected, and in the whole process of their actual production, there will be some rolling bearings. The problem of damage, or the unevenness in the whole process of all the parts rotating back and forth, then the temperature change will be harmed at this time, so there is compensation for the offset among them.
