[0002] Overrunning clutch is a device with self-clutching function, which is mainly used for power transmission and separation between the prime mover and the working machine, or between the driving shaft and the driven shaft inside the machine. At present, the structure of the traditional overrunning clutch widely used in the market is as follows: Figure 1 As shown, the conventional overrunning clutch mainly comprises a clutch inner ring 30, a clutch outer ring 40, and an overrunning clutch assembly 50 assembled between the clutch inner ring 30 and the clutch outer ring 40, and the clutch inner ring 30 is assembled on the transmission shaft 60 through a key 80 or an expansion sleeve. Therefore, the conventional overrunning clutch is in a state of always enabling the overrunning function, and lacks the ability of manually intervening to enable or disable its overrunning function.
[0003] With the increasing complexity and diversified demands of modern production lines, there are frequent scenarios in many actual working conditions where the overrunning clutch overrunning function needs to be temporarily disabled.

[0036] like Figure 2 or Figure 3As shown, the overrunning clutch with disabled overrunning function of the present invention comprises an overrunning clutch body 10 and a sliding half clutch 20. The overrunning clutch body 10 is used to be assembled on a transmission shaft 60. For the convenience of description, the axial direction of the transmission shaft 60 is defined as the left and right direction. The overrunning clutch body 10 comprises a clutch inner ring 30, a clutch outer ring 40, and an overrunning clutch assembly 50 assembled between the clutch inner ring 30 and the clutch outer ring 40. The clutch inner ring 30 is fixedly assembled on the transmission shaft 60, thereby the overrunning clutch body 10 is assembled on the transmission shaft 60 as a whole; the clutch inner ring 30 is also provided with an inner ring protruding shaft section 31 extending rightward toward the sliding half clutch 20, and the inner ring protruding shaft section 31 protrudes rightward from the clutch outer ring 40. The sliding half-clutch 20 is circumferentially fixed to the inner ring protruding shaft section 31, so that the sliding half-clutch 20 and the clutch inner ring 30 rotate synchronously; the sliding half-clutch 20 is assembled on the inner ring protruding shaft section 31 so as to be movable leftward and rightward in the direction approaching or moving away from the clutch outer ring 40, and the sliding half-clutch 20 is distributed on the right side of the clutch outer ring 40; a first meshing tooth 41 is fixedly provided on the right end face of the clutch outer ring 40 facing the sliding half-clutch 20, and a second meshing tooth 21 is fixedly provided on the left end face of the sliding half-clutch 20 facing the clutch outer ring 40, and the first meshing tooth 41 and the second meshing tooth 21 can be engaged or disengaged by the leftward and rightward translation of the sliding half-clutch 20.
[0037] When the sliding half clutch 20 moves to the right in a direction away from the clutch outer ring 40 until the first meshing tooth 41 is disengaged from the second meshing tooth 21, as shown in FIG. Figure 2 As shown, the overrunning clutch is in the state of enabling the overrunning function. During operation, the clutch inner ring 30 rotates together with the transmission shaft 60. Since the first meshing teeth 41 are disengaged from the second meshing teeth 21, the sliding half-clutch 20 rotates synchronously with the clutch inner ring 30, but the sliding half-clutch 20 does not restrict the clutch inner ring 30. At this time, the matching relationship between the clutch inner ring 30, the clutch outer ring 40 and the overrunning clutch assembly 50 in the overrunning clutch body 10 is the same as that of the traditional overrunning clutch, which is equivalent to the overrunning clutch body 10 switching to the state of enabling the overrunning function, that is, it is determined that the overrunning clutch involved in this application has enabled its overrunning function.
[0038] When the sliding half clutch 20 moves to the left in the direction close to the clutch outer ring 40 until the first meshing teeth 41 mesh with the second meshing teeth 21, as shown in FIG. Figure 3As shown, the overrunning clutch is in a state where the overrunning function is disabled. During operation, the clutch inner ring 30 rotates together with the transmission shaft 60. Since the first meshing teeth 41 are meshed with the second meshing teeth 21, when the sliding half clutch 20 rotates synchronously with the clutch inner ring 30, the meshing of the first meshing teeth 41 and the second meshing teeth 21 drives the clutch outer ring 40 to rotate synchronously, which also causes the clutch outer ring 40 and the clutch inner ring 30 to rotate synchronously, which is equivalent to the clutch outer ring 40 and the clutch inner ring 30 being in a fixed state, and the two rotating completely synchronously, and no overrunning will occur, which is equivalent to the overrunning clutch body 10 switching to a state where the overrunning function is disabled, which is also considered to be the overrunning clutch involved in this application having its overrunning function disabled.
[0039] Therefore, the present application controls whether the first meshing tooth 41 and the second meshing tooth 21 are disengaged or engaged by controlling the left and right movement of the sliding semi-clutch 20, and correspondingly controls the enabling or disabling of the overrunning function of the overrunning clutch, thereby temporarily shutting down the overrunning function of the overrunning clutch and restoring the original overrunning function of the overrunning clutch after the problem is solved. This allows users to flexibly enable or disable the overrunning characteristics of the overrunning clutch as needed, greatly improving the adaptability and operational flexibility of the equipment, effectively responding to special needs encountered in a variety of work scenarios, and ultimately better adapting to the complex and changeable actual needs of modern production lines, effectively improving production efficiency and equipment utilization.
[0040] Furthermore, if Figure 2 or Figure 3 As shown, the overrunning clutch with the overrunning function disabled also includes a guide key 70 parallel to the inner ring protruding shaft section 31, the guide key 70 is fixed in the keyway on the outer peripheral surface of the inner ring protruding shaft section 31, and an axially penetrating guide groove 22 is provided on the inner peripheral surface of the sliding half clutch 20, the guide key 70 is inserted in the guide groove 22, and the two are slidably matched. In this way, the left and right translation of the sliding half clutch 20 is more stable, ensuring that the first meshing teeth 41 and the second meshing teeth 21 can be accurately meshed, and improving the reliability of the overrunning clutch disabling its overrunning function.
[0041] Furthermore, if Figure 2 or Figure 3 As shown, the clutch inner ring 30 is fixedly assembled on the transmission shaft 60 by a key 80 (such as a flat key or a spline, etc.). Alternatively, the clutch inner ring 30 is fixedly assembled on the transmission shaft 60 by an expansion sleeve. In addition, the first meshing teeth 41 are integrally formed on the end face of the clutch outer ring 40, and the second meshing teeth 21 are integrally formed on the end face of the sliding half clutch 20, thereby improving the structural strength of the clutch outer ring 40 and the sliding half clutch 20, so that the overrunning clutch capable of switching to enable or disable the overrunning function is durable.
[0042] Furthermore, the overrunning clutch with the overrunning function disabled can be switched manually or automatically when switching the state of enabling or disabling the overrunning function. When switched manually, the sliding half-clutch 20 is manually driven to move left and right. When switched automatically, the overrunning clutch with the overrunning function disabled also includes a control system and a switching drive source, the switching drive source is connected to the control system in communication, the switching drive source is connected to the sliding half-clutch 20 in transmission, and drives the sliding half-clutch 20 to move; preferably, the switching drive source is a motor, an electric cylinder, a hydraulic cylinder or a pneumatic cylinder.
[0043] In summary, the overrunning clutch involved in this application has manually selectable functionality, and can flexibly choose to enable or disable its overrunning characteristics as needed, effectively responding to special needs encountered in various work scenarios, that is, in certain circumstances, it is necessary to temporarily shut down the overrunning function of the overrunning clutch, and quickly restore its original overrunning function after the problem is solved, thereby greatly improving the adaptability and operational flexibility of the equipment, better adapting to the complex and changeable actual needs of modern production lines, and improving production efficiency and equipment utilization. Without interfering with the normal production process, the overrunning clutch involved in this application can easily disable and enable its overrunning function, ensuring the continuity and efficiency of the production line; when the overrunning function of the overrunning clutch is disabled, the overrunning clutch is equivalent to a coupling, and the input end and the output end are synchronized; when the overrunning function of the overrunning clutch is enabled, the overrunning clutch is equivalent to a traditional overrunning clutch, and its performance is no different from that of a traditional overrunning clutch.
[0044] In summary, the present invention effectively overcomes various shortcomings of the prior art and has high industrial utilization value.
[0045] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
