The following detailed description of the embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
In the present specification, terms of orientation or positional relationship such as up, down, left, right, inside, outside, front, rear, head, and tail are established based on the orientation or positional relationship shown in the drawings. The corresponding positional relationship may also vary depending on the drawings, and therefore, should not be construed as limiting the scope of protection.
In the present invention, the terms "mounted," "connected," "fixed," and the like are to be understood in a broad sense, and for example, may be fixedly connected, detachably connected, integrally connected, mechanically connected, electrically connected or capable of communicating with each other, directly connected, indirectly connected through an intermediate medium, or communicated between two components, or interacting between two components. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
This embodiment describes a radial tab clutch that employs a radial arrangement that operates without axial movement, reducing the axial space occupied.
As shown in fig. 2 to 4, the clutch includes a driving member 1, an operating hand wheel 2, a driven member 3, a sliding block 4, a tray 5, a thrust bearing 6, a cylindrical pin 7, a spring 8, a long screw 9, a pin shaft 10, a retainer ring 11, a positioning spring seat 12, a positioning pin 13 and an operating spring seat 14. Wherein, the driving part 1 can be a stranded cable cylinder of the clutch, and the driven part 3 can be a chain wheel of the clutch.
Wherein, the lower side part of the driving part 1 is connected with the inner side of the tray 5 through a cylindrical pin 7, and the tray 5 is arranged on a thrust bearing 6 on the driven part 3. The thrust bearing 6 may support the pallet 5 and the driving member 1 when the clutch is disengaged to reduce friction. The outer side of the upper surface of the tray 5 is provided with a sliding groove along the radial direction, a plurality of sliding grooves are uniformly distributed around the axis of the tray 5 as the center, and the bottom in each sliding groove is padded with a copper sheet for reducing friction and improving wear resistance. The sliding block 4 is arranged on the copper sheet and can slide in the sliding groove along the radial direction, the upper surface of the installed sliding block 4 does not exceed the top surface of the sliding groove, the driven part 3 is provided with an opening corresponding to the sliding groove, the sliding block 4 slides outwards to abut against the inner side of the driven part 3 and is embedded into the opening when being aligned with the opening on the driven part 3, and therefore the driving part 1 is jointed with the driven part 3. Preferably, the edge of the slider 4 has a rounded shape to facilitate the movement of the slider 4 into and out of the opening in the follower 3, thereby preventing jamming.
The control hand wheel 2 is sleeved on the tray 5 between the driving part 1 and the driven part 3 and can rotate on the tray 5. The check ring 11 is arranged between the top of the inner vertical surface of the operating hand wheel 2 and the bottom surface of the driving part 1, so that the driving part 1 can be prevented from being worn when the operating hand wheel 2 rotates. Spiral guide holes corresponding to the number of the sliding grooves are formed in the middle of the control hand wheel 2, a pin shaft 10 penetrates through the spiral guide holes and is fixed on the sliding block 4, an external thread is arranged at the upper end of the pin shaft 10 and is connected with the inner end of a long screw rod 9 through a thread, and the outer end of the long screw rod 9 is supported and connected into a control spring seat 14 on the driving part 1 through a spring 8. In this embodiment, the driving part 1, the control hand wheel 2, the driven part 3 and the tray 5 are coaxially arranged, the axis is taken as the center, 3 chutes are uniformly distributed and surrounded, and the stable connection between the control hand wheel 2 and the sliding block 4 on the tray 5 can be ensured through the stable support of 3 points. The inner side wall of the spiral guide hole takes the center of the control hand wheel 2 as the center of a circle, the radius of the outer side wall is gradually reduced, and the reduction of the radius of the outer side wall is equal to the radial movement distance of the sliding block 4; in this embodiment, the radius of the outer sidewall is gradually decreased in a clockwise direction, and when the pin 10 moves along the spiral guide hole, the spiral guide hole tightly presses the pin 10, thereby dragging the slider 4 to move in a radial direction. The inner side wall of the spiral guide hole can be provided with a thickened part to increase the contact surface with the pin shaft 10, so that the stress of the pin shaft 10 is more uniform.
The positioning spring seat 12 is arranged on the outer side of the control hand wheel 2, the positioning pin 13 is arranged in the positioning spring seat 12 through the spring 8 and abuts against the positioning spring seat 12 through the spring 8, positioning holes are respectively formed in the positions, corresponding to the positioning pin 13, of the driving part 1 in the engaging and disengaging states of the clutch, the positioning pin 13 is ejected out of the positioning spring seat 12 through the spring 8, the positioning pin 13 is inserted into the positioning holes to fix the control hand wheel 2, and therefore misoperation caused by the fact that the control hand wheel 2 rotates along with inertia is avoided.
When the operating hand wheel 2 is rotated anticlockwise, the pin shaft 10 drives the sliding block 4 to slide inwards to the sliding groove under the action of the spiral guide hole, the clutch is disengaged, the positioning pin 13 is pushed into the positioning hole by the spring 8, and the operating hand wheel 2 is prevented from rotating along with inertia. When the control hand wheel 2 is rotated clockwise, the spiral guide hole releases pressure, the pin shaft 10 moves outwards along the spiral guide hole under the action of the spring 8 and the long screw 9 to drive the sliding block 4 to slide outwards, the sliding block 4 is embedded into the opening along with the rotation of the driving part 1 to be aligned with the opening on the driven part 3, the clutch is connected, and the spring 8 pushes the positioning pin 13 into the positioning hole to prevent the control hand wheel 2 from rotating along with inertia.
While the principles of the invention have been described in detail in connection with the preferred embodiments thereof, it will be understood by those skilled in the art that the foregoing embodiments are merely illustrative of exemplary implementations of the invention and are not limiting of the scope of the invention. The details of the embodiments are not to be interpreted as limiting the scope of the invention, and any obvious changes, such as equivalent alterations, simple substitutions and the like, based on the technical solution of the invention, can be interpreted without departing from the spirit and scope of the invention.
