Locking plates engage a keyway in a shaft or adapter sleeve and are attached to the side face of the nut by two bolts secured with locking wire.
A locking plate consists of a plate, two hexagonal head bolts with drilled heads and lock wire to secure them
Spacers are the small parts inserted in-between the two bearings of your skate wheel axles. They take care of the coherence between the two bearings, in order to optimize the matching and synchronization of their rotation. The bearings lean on them when tightened.

Because plastic gears have the advantages of low transmission noise, vibration absorption, self-lubricating, and high efficiency in mold processing. In recent years, more and more applications of plastic gears in the gear industry have become a worldwide trend.
However, at present, the middle and low gear molds can be produced in China, and high-grade gear molds rely on imports. There are not many factories that specialize in gear molds in China, and most of them are made by gear factories themselves. In the application range of gear molds, the demand for plastic gear molds is relatively large, and the market has great potential.
Related experts in the industry put forward three strategies for future development:
First, to speed up industrial restructuring; In the future development, the gear mold industry must first pay more attention to the strategic adjustment of its product structure, so that the structure of high-precision molds with high precision to get faster development. At the same time, the mold industry should also closely follow the market's needs to develop. There is no product demand, product replacement, there will be no technical progress in the mold industry, there will be no mold products on the scale, on the grade. The level of mold technology, to a large extent, determines the product quality, efficiency and new product development capabilities.
Second, to speed up the implementation of industry standards; At present, there is no national standard for the processing of gear molds, and there is no existing industrial standard, especially in the plastic gear mold. Technical standards are a relatively open standard. However, it is very difficult to make product standards. It is necessary to consider various aspects such as experimental standards, accuracy standards, and test device standards for gear molds.
Third, to strengthen the density of cooperation between industries; the development of modern industry is a mutually cooperative relationship, which is equally important for the gear mold industry. This kind of cooperation is based on the direct cooperation of industry research. For example, several universities are studying gear molds, focusing on the strength of gear industry and some university research institutions, and doing integration research and cooperation on process and equipment, plastic internal deformation laws, and so on.
At the same time, from the perspective of the entire industry, the sound of gear molds is very small and it is in a spontaneous state, and the establishment of related professional associations is precisely to change this situation. This is to focus on exploring and resolving the problems in the production of small module gears so as to promote the development of the domestic precision gear mold industry.
Under the trend of great development in the gear industry, especially the plastic gear industry, the response to market changes in the country is not sensitive enough. It is difficult for supporting research to keep pace with market demands. The domestic precision gear molds still need to be in line with the development level of the world's gear molds.
The most common model is shown on the 3D diagram below (in blue): a floating collar spacer with an axle of 8 mm.
Domestic precision gear molds need to be aligned with the development of world gear molds
It is reported that the domestic gear mold industry can be described as mixed, and the joy is that the domestic gear mold production has a certain basis, and the rapid development of plastic gears will also bring greater market space for gear mold. The worry is that compared to the advanced production level of foreign gear molds, there is still a certain gap between the level of domestic production gear molds, and in the gear industry, especially the development of plastic gears industry, China’s response to market changes is not keen enough. , supporting research to keep up with market demand is a bit difficult.
