Description

Technical Field

[0001] The utility model relates to the field of rope collecting discs, in particular to an adjustable pressure friction device. Background Art

[0002] The structure of the current rope making machine includes a rope collecting drum. The shell of the current rope collecting drum is connected by a clamp, which may become loose during long-term use, thereby affecting the sealing performance, and thus needs to be improved. Utility Model Content

[0003] The purpose of the utility model is to provide an adjustable pressure friction device to solve the problems raised in the above-mentioned background technology, which has the advantages of continuously applying pressure and avoiding the problem of looseness caused by long-term use of the clamp structure.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable pressure friction device, comprising a shell, a shaft body passing through the middle of the shell, a friction block placed on one side of the shell, a sprocket sleeved on the outer side of the friction block, a first inclined surface provided on the side of the friction block facing the sprocket, a second inclined surface provided on the side of the sprocket facing the friction block, a fixed block integrally connected to the interior of the sprocket, a bearing installed in the sprocket, one side of the bearing abuts against the fixed block, a cover plate located on the side of the sprocket away from the friction block is connected to one side of the shell, a nut is threadedly connected to one end of the shaft body, and a spring is provided between the nut and the sprocket.

[0005] By adopting the above technical solution, the spring continuously applies pressure to one side of the sprocket, so that the sprocket continues to squeeze the side of the friction block, so that the two can remain in an squeezed state even after long-term use, thereby avoiding the problem of looseness caused by long-term use caused by the clamp structure. The setting of the first inclined surface and the second inclined surface makes the connection between the two closer when the sprocket moves toward the friction block. The dynamic process is that the rotation of the shaft drives the friction block to rotate, and the sprocket and the friction block are in a squeezed state, thereby driving the sprocket to rotate. If there is no spring and no pressure on the two, the sprocket will not rotate.

[0006] As a further solution of the utility model: the shaft body is sleeved with a first sealing ring located between the fixed block and the friction block.

[0007] By adopting the above technical solution, the first sealing ring plays a sealing role.

[0008] As a further solution of the utility model: an oil seal groove is provided on one side of the cover plate, and sealing oil is placed in the oil seal groove.

[0009] By adopting the above technical solution, sealing oil is placed in the oil seal groove to play a sealing role.

[0010] As a further solution of the present utility model: a rotating groove recessed inward is provided on the side surface of the nut.

[0011] By adopting the above technical solution, it is convenient to place an external flat screwdriver in the rotating groove, so as to rotate the nut and adjust the tightness of the spring.

[0012] As a further solution of the present utility model: an extension plate is integrally connected to the side of the sprocket facing the nut.

[0013] By adopting the above technical solution, the setting of the extension plate increases the contact area between the spring and the sprocket.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] The spring continuously applies pressure to one side of the sprocket, so that the sprocket continuously presses against the side surface of the friction block, so that the two can maintain the pressing state after long-term use, thus avoiding the loosening problem caused by the hoop structure after long-term use. The settings of the first inclined surface and the second inclined surface make the connection relationship between the sprocket and the friction block closer when the sprocket moves towards the friction block.
