Description

Technical Field

[0001] This utility model relates to the field of bridge gear technology, and in particular to a bridge gear for screw caps. Background Technology

[0002] A bridge gear is a transition gear in a mechanical transmission system. It is installed between the primary and secondary gears and transmits torque through gear meshing while maintaining the same direction of rotation between the primary and secondary gears, without changing the transmission ratio.

[0003] A search revealed Chinese Patent Publication No. CN120866979A, which discloses a composite spinning bridge gear assembly, relating to the field of textile technology. Specifically, it includes a gear shaft, a connecting sleeve fixed to the outer wall of the gear teeth, and gear teeth disposed on both sides of the connecting sleeve. A double-end sealing assembly for sealing is provided on one side of each gear tooth near the connecting sleeve, and a single-end sealing assembly for sealing with the gear shaft is provided on the other side of each gear tooth. A connecting ring is fixed to the inner end face of each gear tooth, and the connecting ring is rotatably connected to the outer wall of the connecting sleeve with a clearance fit. This invention sets the entire bridge gear as a combination of gear teeth and a connecting sleeve, and uses a buffer tension spring to achieve a rotational tension force between the gear teeth and the connecting sleeve. Therefore, when tooth backlash occurs due to wear, the two gear teeth rotate relative to the connecting sleeve while meshing, thereby using the opposite sides of the teeth of the two gear teeth to form a tooth profile with a wider tooth width for meshing, compensating for wear gaps.

[0004] A search revealed that Chinese Patent Publication No. CN222374859U relates to a bridge gear and its components for a compact spinning device. The bridge gear meshes with a front roller gear on the front roller and a lower compacting roller gear on the lower compacting roller. The bridge gear includes involute bridge teeth and bridge tooth grooves. When the bridge teeth and the front roller tooth grooves meet at the pitch circle, the tooth clearance h1 between the bottom surface of the root of adjacent bridge tooth grooves and the highest point of the top surface of the corresponding front roller teeth is between 0.40±0.05mm. The bridge tooth grooves have an arc surface or plane tangent to the involute curve and transition to the root bottom surface through tooth root fillets R on both sides. The width b of the two tooth root fillets R of the bridge tooth groove is between 1.10±0.05mm. This utility model can increase the tooth groove capacity of the bridge gear, reduce the impact of tooth groove accumulation on the front roller's bounce on spinning quality, extend maintenance time, and reduce production costs.

[0005] However, in the existing technology, it is not convenient to select different sizes of bridge gears according to the size of the main gear. When the required size of the bridge gear changes, the bridge gear needs to be disassembled and replaced, which is not practical. In addition, the existing gear bearings are prone to breakage under long-term use.

[0006] To address this issue, we propose a bridge gear for screw caps. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing a bridge gear for screw caps.

A fourth weight-reducing hole is provided on the first chain gear inside the first chain teeth, and the fourth weight-reducing hole penetrates the first chain gear.

[0013] More preferably, a second chain gear is fixedly connected to the connecting rod on one side of the first chain gear.

[0017] More preferably, the spacing between the first gear, the second gear, and the third gear is the same, and the gear bearing is made of stainless steel.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: The workbench is equipped with first, second, and third gears of different sizes, which are fixed to the connecting rod. This allows for easy selection of different sizes of bridge gears by simply moving the connecting rod laterally according to the size of the main gear. When the required size of the bridge gear changes, it is not necessary to disassemble and replace the bridge gear, making it highly practical.

[0019] By fixing the gear bearing and the connecting rod together, the force of each gear can be transmitted to the gear shaft when it rotates, and the force of the gear shaft can be transmitted to the connecting rod. The gear bearing is less likely to break under long-term use. Attached Figure Description
