Description

Technical Field

[0001] This utility model relates to the field of belt technology, and in particular to a belt roller connection structure. Background Technology

[0002] The drive belt roller, also commonly known as the transmission roller or drive drum, is a key component of a belt conveyor. It is the primary power transmission component, relying on the friction between itself and the conveyor belt to drive the belt and thus achieve continuous material transport. It is the power source of the belt conveyor, responsible for transmitting power from the electric motor to the conveyor belt, driving the belt and materials for continuous transport. Regular maintenance and upkeep are necessary to ensure the normal operation of the drive belt roller and extend its service life.

[0003] The existing roller and drive shaft connection structure involves connecting the roller to the drive shaft via a non-standard expansion sleeve after machining. However, the machining time for non-standard expansion sleeves is long and the cost is high. Even if some connections are made via standard expansion sleeves, a standard expansion sleeve is installed outside the drive shaft. The standard expansion sleeve is connected to the roller via a plug. Plugs are installed at both ends of the roller and are welded to the roller. Both sides of one plug can be welded to the roller, while the plug on the other side can only be welded to one side. Over a long period of use, the weld joints are prone to cracking.

[0004] Therefore, we propose a belt-pulley connection structure. Utility Model Content

[0005] In response to the shortcomings of the existing production technology, the applicant provides a belt roller connection structure in which the roller is connected to the drive shaft through a standard expansion sleeve and a transition shaft. The cost of the standard expansion sleeve is much lower than that of the non-standard expansion sleeve, and the transition shaft is easier, faster and cheaper to process. The overall manufacturing, assembly and subsequent maintenance are very convenient.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A belt-pulley connection structure includes:

[0008] Drive shaft;

[0012] Its further features are:

[0013] The drive shaft is equipped with a limiter to prevent axial movement of the drive shaft when it is installed on the bearing housing.

[0014] The limiting component includes a limiting ring and an adjusting screw, and the position of the limiting ring is adjusted by adjusting the adjusting screw.

[0015] The drive shaft has a keyway at each end, and the transition shaft has a keyway on its inner side. The key is located in the keyway on the shaft and the keyway on the transition shaft.

[0016] Both ends of the roller are provided with holes for the outer diameter of the expansion sleeve, and the standard expansion sleeve is set in the holes for the outer diameter of the expansion sleeve.
