Synchronous belt pulley synchronizes with technological informatization

People use computers to calculate, analyze, and compare various possible design solutions, and achieve ideal results through optimization For example, in analyzing the contact between synchronous belt teeth and surfacesA program has been developed to calculate the angle between the meshing line and the relative velocity, as well as for the calculation of elastohydrodynamic lubrication and geometric parameters. Also, in the calculation of synchronous belt wheel shaping and synchronous belt wheel bearing capacityThere are programs for calculating abilities China has developed the program software GB3480-83 for calculating the bearing capacity of involute cylindrical synchronous belt pulleys for production applications

In terms of synchronous belt wheel processingThe entire cutting process can be controlled by a computer Ensure stable and reliable manufacturing quality At present, China is researching the application of microcomputers to calculate the gear cutting adjustment card of bevel synchronous belt pulleys, which can be used toAdjust processing deviations in a timely manner This achieves a relatively ideal position of tooth contact and greatly improves work efficiency.In addition, according to the principle of numerical control, the synchronous belt wheel company has applied microcomputers to parabolic shape the helical tooth surface of the toroidal worm, which has been applied in production. Although this work is still in its infancy in China,But it is of great significance for improving the manufacturing quality and technological level of synchronous belt pulleys.

Synchronous belt pulley devices are developing in the direction of miniaturization, high speed, and standardization The application of extraordinary synchronous pulleys, the development of synchronous pulleys and synchronous belt devices, low vibrationThe development of low-noise synchronous belt pulley device is a characteristic of synchronous belt pulley design To achieve the goal of miniaturization of synchronous belt pulley devices, the load-bearing capacity of existing involute synchronous belt pulleys can be improvedpower. Hard tooth surface technology is widely used in various countries to increase hardness and reduce device size; It can also be applied to extraordinary tooth shapes represented by circular arc synchronous pulleys.Nowadays, synchronous pulleys are increasingly used in large-scale transmission devices such as metallurgy, mining, and cement rolling mills due to their advantages of small size, good coaxiality, and high efficiencyThe more.

Main parameters and corresponding meanings of synchronous belt wheels

The distance measured on this circle between the corresponding points of adjacent teeth on the pulley should be equal to the pitch Pb of the synchronous belt. If these two conditions can be met, it can ensure smooth meshing between the synchronous belt and the pulley. The circle on the synchronous belt wheel that is tangent to the belt pitch line and rolls against it is called the pitch circle of the belt wheel. The distance between the corresponding points of adjacent two teeth measured on the pitch circle is called the pitch of the belt wheel, represented by Pp. If the number of teeth on the pulley is z and the pitch is Pp, then the pitch diameter of the pulley is d=ZPp/π (mm). When the calculated diameter of the pulley pitch circle is smaller than the bandwidth, to avoid affecting the lifespan of the belt, the pulley diameter should be appropriately increased.

The tooth profile angle of the pulley: The tooth profile angle of the pulley has a significant impact on the meshing and transmission performance between the belt teeth and the gear teeth. When the tooth profile angle is too small, the groove shape of the synchronous gear teeth is approximately rectangular. When the belt teeth enter the meshing of the Jiangmen synchronous belt pulley, significant interference will occur, which can easily cause wear and local fracture of the belt teeth working surface. If the tooth profile angle is too large, it will cause the radial component of the normal force of the tooth on the toothed working surface to be too large, causing the toothed belt to slide outward along the tooth groove, which is prone to tooth crawling and jumping. According to the experiment, when Φ=20 ° -30 °, the interference between the gear teeth and the belt teeth is small, and the tooth profile angle is similar to that of the synchronous belt, which is more suitable. Therefore, the commonly used tooth profile angle is 20 ° -25 °, and the tooth profile angle deviation is generally required to be within plus or minus 1.5 °.

Any synchronous pulley user needs the pulley to present a very good application effect in order to optimize the operation and use of the equipment, thereby making related work more optimized. From an application perspective, for pulley users, customizing synchronous pulleys requires the following tasks to be done:

Wheel selection work: Regardless of the type of product, only when the user ensures that they are purchasing a very high-quality and suitable product, can there be a possibility of optimizing the application. So from an application perspective, if users want to optimize the application of synchronous pulleys, they also need to do a good job in selecting pulleys first, in order to ensure that they purchase pulleys with good quality, suitable size and accuracy.

Installation of pulleys: When using synchronous pulleys, it is necessary to install both the pulley and the synchronous belt at the same time, in order to achieve the best installation state of the pulley and present a good operating effect. On this basis, the entire equipment will present a very good operating effect. Afterwards, users also need to pay attention to the inspection and maintenance of the synchronous pulley during use, in order to ensure that the pulley can be used normally for a long time.
