Description

Technical Field

[0001] The utility model relates to the technical field of large-scale double-shaft circular vibrating screens, in particular to a novel driving side forced synchronization device for large-scale double-shaft circular vibrating screens. Background Art

[0002] With the continuous increase in annual production capacity in industries such as coal, aggregates, and metallurgy, the number of users' demands for large-scale double-axis circular vibrating screens is increasing. This type of screen has a wide range of applications, a simple structure, and is easy to maintain, and is favored by more and more users. The two sets of vibrators of the large double-axis circular vibrating screen need to rotate synchronously in the same direction, so a forced synchronization device must be provided - synchronous wheel + synchronous belt. At present, most of the synchronous devices on the market are designed on the non-drive side, and the synchronous wheel is installed on the vibrator. The center distance of the two synchronous wheels in this structure is determined during the design and cannot be adjusted. However, in the actual manufacturing process, there is a certain error in the length of the synchronous belt. If the synchronous belt is shorter than the required size, it will be difficult to install and subject to large axial force; if the synchronous belt is longer than the required size, it will be unstable in operation and easy to drop the belt. Therefore, this structure has certain defects, and it is easy to fail during use, resulting in the inability to use the equipment normally. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a new large-scale dual-axis circular vibrating screen driving side forced synchronization device, which has stable and reliable structural performance and strong practicality, solves the problem of high equipment failure rate and inability to be used normally caused by the forced synchronization device being set on the non-driving side, and can effectively solve the problems in the background technology.

[0005] Furthermore, two bearing seats are fixed on each transmission shaft, and the bearing seats are connected to the transmission shaft through bearings. The transmission shaft can be fixed to the frame through the bearing seats, making installation more convenient, thereby ensuring that the synchronous transmission assembly is in a tensioned state.

[0006] Furthermore, the synchronous transmission assembly includes two synchronous pulleys, which are respectively fixed on two transmission shafts. The center of the synchronous pulley is a conical sleeve structure, and the two synchronous pulleys are driven by a synchronous belt. When one transmission shaft rotates, the installed synchronous pulley can be driven to rotate. Through the synchronous pulley and synchronous belt transmission, the other transmission shaft can be driven to rotate, thereby ensuring the synchronous rotation of the two transmission shafts, thereby ensuring the synchronous rotation of the two sets of exciters, and playing a role of forced synchronization.

[0007] Furthermore, the large belt pulley and the small belt pulley are evenly provided with V-belt grooves, and the V-belt grooves on the large belt pulley and the small belt pulley correspond to each other one by one.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: during installation, the two vibrators are first fixedly installed correspondingly, and each vibrator is installed with a universal drive shaft and a drive shaft at the same time, and then a synchronous transmission assembly is installed between the two drive shafts. After the installation is completed, the drive shaft is fixed to the frame through the bearing seat, so that the center distance of the two synchronous pulleys can be adjusted, which is convenient for the installation and tensioning of the synchronous belt, and then the motor is installed, and finally the V-belt, large pulley and small pulley are installed. The drive shaft can be driven to rotate by the motor, and when one drive shaft rotates, the installed synchronous pulley can be driven to rotate, and the other drive shaft can be driven to rotate through the synchronous pulley and synchronous belt transmission, so as to ensure the synchronous rotation of the two drive shafts, so as to ensure the synchronous rotation of the two groups of vibrators, which plays a role of forced synchronization. The new large-scale dual-axis circular vibration screen drive side forced synchronization device has stable and reliable structural performance and strong practicality, and solves the problem of high equipment failure rate and inability to use normally caused by the forced synchronization device being set on the non-drive side.
