Description

Technical Field

[0001] The utility model relates to the technical field of release bearings, in particular to a pull-type clutch release bearing based on flexible connection. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Nowadays, there are many types and styles of bearings, and different machines and positions use different bearings. The release bearing used on the clutch is one of them. At present, most clutch release bearings use a paddle to poke the force block on the outside of the bearing during operation. Over time, the paddle and the force block are prone to misalignment, and the paddle is prone to damage the force block when misaligned. The clutch release bearing is located on one side of the clutch. The bearing is prone to heat and damage due to lack of lubricating oil after long-term use, which affects the service life of the bearing.

[0003] A flexible-connected pull-type clutch release bearing is disclosed in a Chinese utility model patent with publication number CN217951054U. The utility model solves the problem that the paddle and the force block of the existing clutch release bearing are easily misaligned after a long time, and the paddle is easy to damage the force block when misaligned. A flexible-connected pull-type clutch release bearing includes a bearing body, a power mechanism is arranged on one side of the bearing body, the power mechanism includes a first ring plate arranged on one side of the bearing body, a transmission assembly is arranged on one side of the first ring plate, a fixing assembly is arranged on one side of the transmission assembly, a curved rod is arranged on one side of the transmission assembly, and a fixing block is arranged on one side of the transmission assembly.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: the above-mentioned device drives the first ring piece and the second ring piece by rotating the curved rod, thereby driving the bearing body to move. In this process, the staff needs to fix the first ring piece and the bearing body to each other, and connect the first ring piece and the second ring piece to each other. At this time, the staff needs to use fixing screws to connect the connecting piece with the first ring piece and the second ring piece in turn. During the installation process, the staff needs to keep the first ring piece, the second ring piece and the connecting piece stable, and the operation is relatively complicated, which is not conducive to improving the staff's user experience. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a pull-type clutch release bearing based on flexible connection.

[0006] The above technical purpose of the utility model is achieved through the following technical scheme: a pull-type clutch release bearing based on flexible connection, including a bearing body, a first ring plate arranged on the bearing body, a second ring plate arranged on the bearing body and a power device for driving the first ring plate, a placement groove is provided on the side wall of the first ring plate close to the second ring plate, a fixing groove is provided on the side wall of the second ring plate close to the first ring plate, and a fixing component for fixing the second ring plate is provided on the first ring plate.

[0007] By adopting the above technical solution, when the staff needs to operate the separation bearing, the staff needs to adjust the position of the bearing body. At this time, the staff only needs to make the first ring piece close to the bearing body and make the second ring piece close to the first ring piece and the bearing body at the same time, so that the fixing component can be automatically started and the first ring piece and the second ring piece can be kept stable, thereby reducing the difficulty of the staff's operation. Subsequently, the staff can adjust the position of the first ring piece by operating the power device, thereby adjusting the position of the bearing body.

[0008] Furthermore, the fixing assembly includes a threaded rod threadedly connected in the placement groove, a fixing rod fixed to a side wall of the threaded rod away from the placement groove, and a limiting device arranged on the second ring piece.

[0009] By adopting the above technical solution, when the staff needs to install the second ring piece, the staff needs to make the first ring piece close to the bearing body and make the threaded rod and the placement groove threadedly connected, so that the threaded rod and the fixing rod can be kept stable. Afterwards, the staff only needs to make the second ring piece close to the bearing body and make the fixing rod and the fixing groove mutually connected, so that the limiting device can be automatically started, and then the limiting device limits the second ring piece, thereby reducing the difficulty of operation for the staff.

[0010] Furthermore, a limiting groove is opened on the inner wall of the fixing groove, and the limiting device includes a limiting block slidably arranged in the limiting groove and a limiting spring with one end fixed on the side wall of the limiting block, and the other end of the limiting spring is fixed on the inner wall of the limiting groove.

[0011] Furthermore, an inclined surface is provided on an edge where a side wall of the limit block away from the limit spring and a side wall of the limit block close to the fixing rod intersect.

[0012] Furthermore, a limiting hole matching the limiting block is formed on the side wall of the fixing rod.

[0013] By adopting the above technical solution, when the fixing rod and the fixing groove are connected to each other, as the second ring piece moves, the fixing rod presses against the inclined surface, and then the limit block moves toward the limit spring under the action of the fixing rod, so that the limit block moves completely into the limit groove. Subsequently, when the limit groove and the limit hole are facing each other, the limit block is connected to the limit hole under the action of the limit spring, thereby reducing the difficulty of operation for the staff.

[0014] Furthermore, a receiving groove for receiving the first ring piece and the second ring piece is provided on the side wall of the bearing body.

[0015] By adopting the above technical solution, the stability of the first ring piece and the second ring piece is improved, which is beneficial to improving the user experience of the staff.

[0016] Furthermore, a connecting seam is provided on the inner wall of the accommodating groove, and a blocking piece for blocking the first ring piece is provided in the connecting seam.

[0017] By adopting the above technical solution, when the staff installs the first ring piece, the staff needs to connect the baffle and the connecting seam to each other, so that the baffle can block the first ring piece, thereby reducing the probability of contact between the connection between the power device and the first ring piece and the second ring piece, thereby improving the staff's user experience.

[0018] Furthermore, rubber sheets are provided on the inner walls of the first ring sheet and the second ring sheet.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. In this application, when the staff needs to operate the separation bearing, the staff needs to adjust the position of the bearing body. At this time, the staff only needs to make the first ring piece close to the bearing body, and make the second ring piece close to the first ring piece and the bearing body at the same time, so that the fixing component can be automatically started and the first ring piece and the second ring piece can be kept stable, thereby reducing the difficulty of the staff's operation. Subsequently, the staff can adjust the position of the first ring piece by operating the power device, thereby adjusting the position of the bearing body;

[0021] 2. In this application, when the staff needs to install the second ring piece, the staff needs to make the first ring piece close to the bearing body and make the threaded rod and the placement groove threadedly connected, so that the threaded rod and the fixing rod can remain stable. Afterwards, the staff only needs to make the second ring piece close to the bearing body and make the fixing rod and the fixing groove mutually connected, so that the limit device can be automatically started, and then the limit device limits the second ring piece, thereby reducing the difficulty of operation for the staff;

[0022] 3. In the present application, when the fixing rod and the fixing groove are connected to each other, as the second ring piece moves, the fixing rod presses against the inclined surface, and then the limit block moves toward the limit spring under the action of the fixing rod, so that the limit block moves completely into the limit groove. Subsequently, when the limit groove and the limit hole are facing each other, the limit block is connected to the limit hole under the action of the limit spring, thereby reducing the difficulty of operation for the staff.
