Description

Technical Field

[0001] The utility model relates to the technical field of conveying equipment accessories, and more specifically to an anti-eccentricity screw rod for conveying equipment. Background Art

[0002] Conveying equipment is a mechanical device that transports bulk goods and piece goods from the loading point to the unloading point along a certain route in a continuous manner. When performing transmission operations, the screw with transmission function is a commonly used transmission structure.

[0003] After searching, a transmission screw with an existing announcement number of CN219692163U is found, which includes an output end and an input end. The output end and the input end are an integrated structure, an output thread is provided on the outer surface of the output end, an input thread is provided on the outer surface of the input end, an injection groove is provided at the end of the output end, an oil storage groove is provided at one end inside the injection groove, and an oil outlet is provided in the gap at the end of the output thread; an injection groove is provided on the output end, and a through-type oil outlet is provided in the injection groove, by adding lubricating oil to the injection groove, the oil flows through the oil outlet to the groove between the output threads, and as the output end rotates slowly, the lubricating oil flows along the thread to play a lubricating role, and a sealing rubber cover that is closed in a natural state is designed at the opening of the injection groove, and the sealing rubber cover is filled through the cross opening, and remains closed and sealed after filling, which can ensure that the small amount of lubricating oil added will not be thrown out as the screw rotates.

[0004] The head of the screw center shaft (i.e. the fixed end of the screw connecting the coupling) is short, while the tail of the screw center shaft (i.e. the screw part) is long, but it is the force-bearing rotating part that bears all the weight of the screw, so that eccentric force occurs in the screw during rotation. After disassembling the screw for inspection, it was found that both the shaft and the fixed end of the screw (the head of the center shaft) were damaged. Therefore, it must be the eccentric force that caused the damage, which caused the eccentric rotation of the screw, resulting in bottle jamming, bottle squeezing, wear and other problems. Therefore, we proposed an anti-eccentric screw for conveying equipment to solve the above problems. Utility Model Content
