Description

Technical Field

[0001] This application relates to the technical field of brushing equipment for steel pickling production lines, and particularly to a transmission mechanism for a brushing roll. Background Art

[0002] During the production of steel, pickling is an important process for removing impurities such as mill scale on the surface of steel. Currently, the brushing system in the strip pickling area usually has multiple brushing machines, and each brushing machine is equipped with multiple brushing rolls. Referring to Figure 1 , the traditional transmission design of the brushing roll is complex and consists of multiple components such as a waterproof sleeve, a connecting sleeve, and a spline sleeve. When starting the motor, the motor transmits power to the spline sleeve, waterproof sleeve, and connecting sleeve through a coupling, and then transmits the power to the roll core of the brushing roll.

[0003] When starting the motor, the motor drives the spline sleeve to quickly enter a high-speed rotation state, resulting in relatively large wear on the key grooves of the spline sleeve and being extremely prone to deformation. It needs to be disassembled and replaced frequently. Due to the complex structure of this transmission mechanism, disassembly and assembly are difficult, time-consuming, and laborious. Moreover, due to the complex structure of the transmission mechanism, there are many gaps in the transmission mechanism composed of multiple components. After the components are worn, displacement and impact are likely to occur, generating relatively large noise. Utility Model Content

[0004] The purpose of this application is to overcome the above technical problems and provide a transmission mechanism for a brushing roll. This mechanism simplifies the complexity of the traditional design, reduces the number of components, thereby reducing wear and noise, and improving the transmission efficiency and the service life of the equipment.

[0005] A transmission mechanism for a brushing roll provided by the utility model adopts the following technical solutions:

[0006] A transmission mechanism for a brushing roll includes a connecting piece and a flange adapter. The connecting piece is fixedly connected to the roll core. A bearing and a positioning sleeve are sleeved on the connecting piece. A base is sleeved on the bearing for supporting the bearing and the connecting piece. The positioning sleeve abuts against the bearing. The flange adapter is connected to the connecting piece and abuts against the positioning sleeve. A coupling is connected to the flange adapter.

The coupling is connected to the flange adapter, and the roll core is driven to rotate through the flange adapter and the connecting piece, thereby realizing the transmission of the brushing roll. The overall transmission structure is simpler, the number of components is reduced, noise can be reduced, the production cost is lowered, and problems such as wear, deformation, and frequent replacement are reduced, improving the service life of the equipment.

The flange adapter is provided with a fixing hole, and a fixing bolt is arranged in the fixing hole.

[0012] Preferably, a plurality of threaded grooves are provided, and a plurality of fixing holes are provided.

[0013] By adopting the above technical solution, that is, using a plurality of fixing bolts to fix the flange adapter and the connecting member, further improves the connection stability between the flange adapter and the connecting member.

[0014] Preferably, the fixing hole is a countersunk hole, the fixing bolt is a countersunk bolt, and the head of the fixing bolt is accommodated in the fixing hole.

[0015] By adopting the above technical solution, when the flange adapter is connected to the coupling, the fixing bolt will not cause excessive wear to the coupling, increasing the reliability of the entire rotating mechanism.

[0016] Preferably, a flat key is provided on the protruding portion, and the flange adapter is key-connected to the protruding portion through the flat key.

[0017] By adopting the above technical solution, the connecting member and the flange adapter adopt a direct connection method and are connected by a flat key.
