Be strict from the source

After strict selection of raw materials, through the repeated forging of high-pressure casting machine, the initial state of the product is formed. From the moment of birth, the service life of the product is determined.

Ingenuity is inseparable from manual welding of an experienced craftsman

A seemingly simple step requires craftsmen with more than 10 years of experience, meticulous manual welding, focusing on quality and appearance, which is enough to make competitors eclipse.

High quality needs to go through many processes

Chamfering, grinding, turning and milling, similar to diamond level process, high requirements to ensure that the product performance, quality and innovation all exceed the expectations of customers.

Directional development

Facing the demand of different application fields, we draw and model the product system that users need, quickly define multiple variables, use 3D model viewer and new sketch tool module

Good products, from the multiple detection

As your professional partner, we advocate products with “Zero defects”. All products must go through multiple and strict quality inspection to form an action closed loop of high quality production, which is also a strong guarantee for SCS to become a reliable partner of many famous brand manufacturers in the world.

How to extend the service life of sprockets and improve measures

The service life of sprockets is relatively short, far from meeting the requirements of production practice. Based on the usage status, processing status, and manufacturing technology of sprockets, some improvement measures have been proposed for sprockets:

How to maintain and upkeep the sprocket

The tightness of the sprocket should be appropriate, as being too tight will increase power consumption and make the bearings prone to wear; Chain wheels that are too loose are prone to jumping and slipping. The tightness of the sprocket is about 2% -3% of the center distance between the two sprockets when lifted or pressed down from the middle of the sprocket.

Reasons for chain wheel wear

The larger the adhesive wear load, the higher the surface temperature, and the more severe the adhesive phenomenon. For metal materials with a certain hardness, a wear rate pressure relationship curve was obtained by conducting wear tests at different pressures. When the pressure reaches more than one-third of the material's hardness, severe wear will occur. According to the stress distribution diagram, it can be seen that the maximum stress contact point is the point of maximum pressure, with a value of 884.4 MPa. Due to the quenching hardness of HRC48~52 at the chain socket, its corresponding hardness value is 4800MPa. Therefore, the pressure is far less than one-third of the material hardness, so adhesive wear is not the main form of sprocket wear.

Precautions for using sprockets

When it comes to using chain wheels, there are several important considerations to keep in mind. Chain wheels, also known as sprockets, are an integral part of many mechanical systems, particularly in power transmission applications. Here are some key points to consider when using chain wheels
