TYPES, MODELS, HARDNESS AND COLOR DISTINCTION AND QUALITY DESCRIPTION OF FLEXIBLE COUPLING ELASTOMERS

1. Types and models of elastomers used in flexible couplings

(1). Star-shaped elastic coupling elastomers

(2). Plum-shaped elastic coupling elastomers

(3). Coupling elastomers for oil pumps

(4). Removable elastic coupling elastomers

2. Hardness and color distinction of flexible coupling elastomers

Because there are many elastomers for flexible couplings, we will not explain them one by one here. We will use the elastomers of commonly used star couplings and plum-shaped couplings as examples. At work, we often hear that red elastomers are good or yellow elastomers are not good, and purple elastomers are better. After research and analysis, good and bad elastomers have no direct relationship with color. Colors are only used for distinction and identification, which is mainly related to the selection of the main material of the elastomer. For example, professional companies will distinguish according to the following colors (Kudosworld transmission brand uses purple, blue and red 98shore A for high product aesthetics). The main material is: German Bayer TPU material.

3. Quality description of star/plum blossom couplings

The number of petals of the elastomer increases with an even number. The larger the even number, the more petals and the larger the model. Elastomers are all made by injection molding or extrusion from the designed mold. Because the main material is polyurethane, it has both outstanding mechanical properties and wear resistance, as well as good damping characteristics and high resilience.

Most molds on the market have the same size, and then there is a mess of branded products and unbranded products, and it is difficult to distinguish between good and bad, and even the strange phenomenon of distinguishing good and bad by color. In order to avoid this situation, Kudosworld Transmission has designed and manufactured special molds for commonly used models. And ensure that the size error value of each molded product is controlled within ±0.03mm, and the hardness value is: 98±2 shore A. If you need higher hardness, wear resistance, corrosion resistance, and high temperature resistance, you need to communicate with Kudosworld Transmission business personnel when ordering.

Summary: Different manufacturers design different molds (the arc pitch circle size of each petal of the elastomer is different), so the assembly size of the elastomer and the flange is different. Then, the same external dimensions and the same numbers in the elastomer markings (GR24/28/38/42/65 for star-shaped elastomers and MT2/3/4/5/6/7/8 for plum-shaped elastomers) are the same, but why can't they be installed or have a short lifespan? Therefore, it is concluded that the problems that affect product quality are: size problems, main material problems, and design and assembly problems. It is crucial to correctly choose a branded professional manufacturer.
