The device 12 may output rotational torque via an output member 16 such as a shaft or another rotating body such as a gear, a belt, or a sprocket. The driven device 14 may include, for example, a conveyor or a reel to which a hose, cable, or steel cable is mounted. It should be understood that the form of the device 14 will depend on the application, and the device 14 may include a variety of devices configured to receive input moments. 1 4 可以通过输入构件 1 8( 诸如轴或者另一转动体例如齿轮、皮带或者链轮之类)输入转动扭矩。 The device 14 may input a rotational torque through an input member 18 such as a shaft or another rotating body such as a gear, a belt, or a sprocket.

The clutch 20 includes a two-way clutch, particularly a two-way overspeed clutch. 1 ) 或者超速的离合器 。 An overspeed clutch is a clutch designed to drive in one direction while idling in the opposite direction (freewhee 1 ) or overspeed . In the driving direction, if the rotational speed of the driven device exceeds the rotational speed of the driving device, the clutch is also idling. The two-way overspeed clutch can drive and overspeed in both directions. 情 性负载溢出，并防止可能会对驱动装置12造成的后驱动损害。 One advantage of an overspeed clutch is that it allows a large amount of emotional load to overflow when stopped , and prevents possible rear drive damage to the drive device 12. 可 以包括 内 构件22、外构件2 4 、安装销26、棘爪28、磁体30和电磁促动器32。 The clutch 20 may include an inner member 22, an outer member 2 4 , a mounting pin 26, a pawl 28, a magnet 30, and an electromagnetic actuator 32.
The inner member 22 is configured to receive input torque from the output member 16 of the drive device 12, and the input torque is selectively transmitted to the outer member 24 of the clutch 20, as described in more detail below. 1 2 延伸或者延伸至装置12的轴(未示出)，该 轴 可以包括输入构件16或者可以联接至输入构件 1 6 。 The member 22 has an annular configuration and can be configured to receive a shaft (not shown) extending from the device 12 or to the device 12, which shaft may include the input member 16 or may be coupled to the input member 16 . 轴 线36转动(图3)。 Referring to FIG. 2, the member 22 may define a key slot 34 or a key configured to respectively engage a key slot in a shaft, thereby coupling the member 22 to the shaft for rotation about a rotation axis 36 (FIG. 3). Referring to FIG. 3, the diameter of the radially outer surface of the member 22 may vary. At each axial end, the diameter of the member 22 may be set to be received in the member 24 and to support the actuator 32, respectively. Between the axial ends of the members 22, the members 22 may form a pawl housing or mounting structure 38. The housing 38 may include a pair of radially outwardly extending, axially spaced apart flanges 40,42. 4 0 、42以及轴向延伸的壁 4 4 形成了 周 向凹陷部 4 6 ，该周向凹陷部被构造成 用 以接收棘爪28。 The flanges 40 , 42 formed in the housing 38 and the axially extending wall 44 form a circumferential recessed portion 4 6 that is configured to receive the pawl 28. Referring to FIG. 4, the housing 38 may define a plurality of radially extending recesses 48 in the wall 44 that are configured to receive the magnet 30. 4 0 、42可以分别限定出多个沿轴向延伸的孔50、52，这些孔围绕凸缘40、42沿周向地等距间隔开。 Referring again to FIG. 3, each flange 40 , 42 may define a plurality of axially extending holes 50, 52, respectively, which are equally spaced circumferentially around the flanges 40, 42. Each hole 50 may be axially aligned with a corresponding hole 52. The holes 50, 52 are configured to oppose opposite longitudinal ends of the mounting pin 26 extending through the recess 44 and the corresponding pawl 28.
将 扭矩传送给从动装置14。 The outer member 24 is configured to transmit torque to the driven device 14. The member 24 has an annular configuration and is arranged radially outside the inner member 22 about the axis 36. 4 的内直径沿着其轴向长度变化。 The inner diameter of the member 24 varies along its axial length. 上 。 Specifically, the member 24 may define a reduced-diameter portion 54 at one axial or longitudinal end of the member 24 that is configured to be received on an axial end portion of the inner member 22 . 4 与构件22之间可以布置有润滑剂薄层。 A thin layer of lubricant may be arranged between the portion 54 of the component 24 and the component 22. 可 以设有轴承(例如套筒轴承或者滚柱轴承)。 Alternatively, a bearing (such as a sleeve bearing or a roller bearing) may be provided between the members 22, 24 . The portion 54 may define a plurality of axially extending, circumferentially located holes 56 configured to receive pins or other fasteners (not shown), and the members 24 may be coupled via pins or other fasteners Go to the input member 18. 4 可以以各种方式联接至输入构件18。 However, it will be understood that the member 24 may be coupled to the input member 18 in various ways. The member 24 may define a portion 58 of increased diameter at the other axial or longitudinal end of the member 24 that is sized to receive the pawl housing 38 of the member 22.

Each depression 60 defines a pair of pawl engaging surfaces 62, 64. In the illustrated embodiment, the recessed portion 60 is substantially trapezoidal, and its surfaces 62, 64 form an obtuse angle with the radial bottom of the recessed portion 60, so that the recessed portion 60 narrows or tapers in a radially outward direction. . 可 以根据棘爪28的形状和取向变化。 It should be understood, however, that the shape and orientation of the recesses 60 and the surfaces 62, 64 are complementary to the shape and orientation of the pawl 28, and therefore may vary depending on the shape and orientation of the pawl 28.
