Main parameters and corresponding meanings of synchronous belt wheels

Synchronous pulley outer diameter do: amp; The pitch distance refers to the distance between the pitch circle of the synchronous pulley and the top circle of the pulley. Due to the contact between the bottom surface of the synchronous belt teeth and the top surface of the belt teeth when the synchronous belt is wrapped around the pulley, the pitch distance of the synchronous belt pulley is equal to the distance from the synchronous belt pitch line to the bottom surface of the belt teeth; Its value depends on the model.

In amp; When the value is fixed, the position of the pulley pitch circle will depend on the pulley outer diameter do. As the pitch of the pulley is measured on the pitch circle, if the value of the pulley outer diameter do is too large or too small, it will cause changes in the pulley pitch, resulting in the pulley pitch not being equal to the belt pitch, causing the pulley and belt to not mesh properly. Therefore, the pulley outer diameter do should be strictly controlled during processing to ensure that its size is within the specified limit deviation range.

Top fillet radius rt of gear teeth: The top fillet radius of gear teeth, like that of double-sided synchronous belt teeth, has a significant impact on the meshing interference between gear teeth and double-sided synchronous belt teeth. When the rounded corner of the belt tooth tip is too small, it will cause interference between the belt tooth and the sharp corner of the tooth tip when it enters the tooth groove. Moreover, the smaller the rounded corner radius, the longer the interference length, and abrasive wear will occur, which will reduce the service life of the double-sided synchronous belt.

At the same time, if the fillet radius of the tooth tip is too small, the sharp angle of the tooth tip will prevent the belt teeth from entering a fully engaged state with the tooth teeth, causing the belt teeth to rest on the tooth groove, resulting in a decrease in the contact area between teeth, and in the processing of V-shaped belt wheels, tooth climbing phenomenon may occur in severe cases. Therefore, it is advisable to adopt a larger value for the top fillet radius of the belt teeth to facilitate proper contact and meshing between the belt teeth and the teeth.

However, it should be noted that increasing the fillet radius rt will correspondingly reduce the actual contact area between the gear teeth and the belt teeth, so the rt value should not be too large. For synchronous belt pulleys with different pitch, their rt values have been specified in various synchronous belt pulley standards.

Introduction to the components of synchronous belt pulley

A synchronous belt pulley can be divided into two components: a synchronous belt and a synchronous wheel. As the name suggests, a synchronous belt pulley consists of a conveyor belt and a toothed belt pulley. As long as the synchronous belt and synchronous wheel are used simultaneously to achieve the desired effect, they alone are useless.

Although it is the interconnection between them, the V-belt pulley company requires corresponding tooth grooves. If the calculation is not complete, deviations will occur. Therefore, it is very important during production and installation, especially during production. The dimensions need to be matched with each other, including pitch, tooth height, belt thickness, etc., which need to be measured and manufactured accurately. The pace during installation is also crucial.

Other precautions: For example, if the axis is not parallel and the frame supporting the pulley needs to meet the necessary rigidity, due to the wide use of synchronous pulleys, V-belt pulley manufacturers must be cautious when manufacturing and installing, as it is a very important component in machinery.

The standardization of the transmission industry has led to joint discussions on the development of synchronous pulleys both domestically and internationally. After years of development in the transmission industry, synchronous pulleys and belts have become ubiquitous in various industries. China's transmission industry has gradually matured, and there are increasing requirements for transmission related products such as synchronous belts and pulleys. Through discussions among industry professionals, many problems and shortcomings have been identified, requiring new planning and calculations in terms of concepts. I believe that foreign experts are also studying this technical problem that troubles the entire industry. So, in order to theoretically promote the development of the new transmission industry, we need to consider several aspects:

(1) Calculation of synchronous belt drive design. The calculation of transmission data is the fundamental basis for selecting synchronous belt and pulley parameter structures, and is influenced by domestic and foreign product specifications and standards. After the establishment of the international calculation method for the tensile strength of transmission belts in 1981, there has been no change for many years. Nowadays, industry personnel have unanimously discovered the drawbacks of this algorithm. Domestic and foreign scholars are devoted to researching and tackling this algorithm problem, proposing a series of algorithms on wear resistance, shear strength, transmission efficiency, and other issues.

(2) Research on the Characteristics of Synchronous Belt Transmission. This is a comparative research topic, and Japanese scholars have analyzed transmission characteristics from tension, rotary transmission errors, and tooth skipping phenomena, and have published multiple documents.

(3) Vibration and noise of synchronous belts. Vibration and noise have always been two aspects that domestic and foreign * * * personnel have been wanting to improve. Japanese and Soviet scholars have expressed their views on the causes of vibration and noise, and discussed methods to reduce them.

In recent years, Chinese and foreign researchers have never stopped researching and exploring the development of synchronous belts and pulleys. It is believed that in the near future, there will be a significant leap in world transmission technology.
