Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile machinery technology, and in particular to a low-speed oil-lubricated jogging transmission device. Background Technology
[0002] A drive roller in textile machinery is a roller used to transmit power in textile machinery. Through rotational motion, it transmits power from one point to another, thereby driving other components of the textile machinery to perform their functions.
[0003] Currently, traditional textile drive rollers on the market often lack anti-reverse mechanisms. This allows the drive rollers to reverse due to inertia after losing power support, leading to a series of hazards. Furthermore, traditional drive rollers operate on a smooth transmission path, which is incompatible with the inching transmission required in textile machinery. Therefore, a further output mode conversion is necessary at the output point, resulting in poor efficiency. Thus, there is an urgent need for a drive roller structure with anti-reverse functionality and an inching transmission method. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a low-speed oil-lubricated jogging transmission device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A low-speed oil-lubricated jogging transmission device includes a worm gear and a steel sleeve. A transmission roller is rotatably installed inside the steel sleeve. The worm gear is mounted on the steel sleeve through a bearing, and a fixing ring is fixedly installed on the inner wall of the worm gear. A special-shaped part is adapted to fit the fixing ring on the outer wall of the steel sleeve. Multiple wedge-shaped parts are fixedly installed on the special-shaped part, and a wedge-shaped cavity is adapted to fit each wedge-shaped part on the inner wall of the fixing ring.
[0007] In addition, a preferred structure is that a first side cover is provided on one side of the worm gear, and the first side cover has multiple threaded holes.
[0008] Furthermore, in a preferred configuration, a second side cover is provided on the other side of the worm gear, and a screw is adapted to be provided on each of the corresponding threaded holes on the second side cover.
[0009] Furthermore, in a preferred configuration, a seal is provided at the connection between the first side cover, the second side cover, and the worm gear, and the internal cavity of the worm gear is filled with lubricating oil.
[0010] In addition, the preferred structure is that the irregular part is composed of multiple counterclockwise inclined columnar bodies, the irregular part is arranged in a ring and fixed on the steel sleeve by screws, and both the irregular part and the steel sleeve are provided with screw grooves to match the screws.
[0011] Furthermore, in a preferred configuration, all wedge-shaped members are fixedly mounted on the top of the columnar body, and the inclined surfaces of the wedge-shaped members are all opened in a clockwise direction.
[0012] The beneficial effects of this utility model are as follows: the rotation of the worm gear can drive the steel sleeve and the transmission roller to rotate. Through the matching arrangement between the irregular part, the wedge part and the fixed ring and the wedge cavity, not only can the steel sleeve and the transmission roller rotate in a point rotation form, but the reverse rotation of the steel sleeve and the transmission roller can also be prevented.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Reference Figure 1-5 The low-speed oil-lubricated jogging transmission device includes a worm gear 1 and a steel sleeve 5. A transmission roller is rotatably installed inside the steel sleeve 5. The worm gear 1 is sleeved on the steel sleeve 5 through a bearing 60, and a fixing ring 4 is fixedly installed on the inner wall of the worm gear 1. A special-shaped part 51 is adapted to the fixing ring 4 on the outer wall of the steel sleeve 5. Multiple wedge-shaped parts 52 are fixedly installed on the special-shaped part 51, and a wedge-shaped cavity 41 is adapted to be opened on the inner wall of the fixing ring 4 corresponding to the wedge-shaped parts 52.
[0021] The worm gear 1 has a first side cover 2 on one side, and the first side cover 2 has multiple threaded holes 21. The worm gear 1 has a second side cover 3 on the other side, and the second side cover 3 has screws 31 that are adapted to fit the threaded holes 21. The worm gear 1 and the retaining ring 4 both have through holes that are adapted to fit the screws 31. By fitting the screws 31 and the threaded holes 21, the first side cover 2 and the second side cover 3 can be fixedly installed on both sides of the worm gear 1.
[0022] In this application, the connections between the first side cover 2, the second side cover 3, and the worm gear 1 are all equipped with seals, and the internal cavity of the worm gear 1 is filled with lubricating oil. This lubricating oil can improve the transmission effect of the worm gear 1 on the steel sleeve 5 and the transmission roller. Furthermore, this application also includes an oil pipe for injecting lubricating oil, which can be disassembled by bolts.
[0023] The irregularly shaped component 51 is composed of multiple counterclockwise inclined columnar bodies. The irregularly shaped component 51 is arranged in a ring and fixedly sleeved on the steel sleeve 5 by screws 53. Both the irregularly shaped component 51 and the steel sleeve 5 have screw grooves adapted to the screws 53. The wedge-shaped components 52 are all fixedly arranged on the top of the columnar bodies, and the inclined surfaces of the wedge-shaped components 52 are all opened in a clockwise direction.
[0024] In this embodiment, the transmission roller is fixedly installed inside the steel sleeve 5, and the worm gear can be driven externally by a drive motor to transmit power to the worm wheel 1. It is worth noting that the specific transmission mechanism between the drive motor, the worm gear, and the worm wheel 1 is prior art, and therefore will not be described in detail in this technical solution.
[0025] Since the worm gear 1 is rotatably mounted on the steel sleeve 5 via the bearing 6, and the steel sleeve 5 is fixedly fitted onto the drive roller, the steel sleeve 5 can rotate inside the worm gear due to friction during the rotation of the worm gear 1, thereby driving the drive roller to rotate. It is worth noting that, due to the limitation of friction, the rotational speed of the steel sleeve 5 and the drive roller is slower than the rotational speed of the worm gear 1.
[0026] Furthermore, a fixing ring 4 is fixedly installed on the inner wall of the worm gear 1, and a shaped component 51 is adapted to fit the fixing ring 4 on the steel sleeve 5. Moreover, the shaped component 51 is composed of multiple counterclockwise inclined columnar bodies. This makes the friction between the worm gear 1 and the steel sleeve 5 smaller when the worm gear 1 rotates clockwise, so that the steel sleeve 5 can rotate within the inner wall of the worm gear 1.
[0027] When the worm gear 1 stops rotating, the steel sleeve 5 and the drive roller may reverse due to inertial force. At this time, the friction between the worm gear 1 and the steel sleeve 5 increases, thereby preventing the steel sleeve 5 from reversing on the inner wall of the worm gear 1.
[0028] Furthermore, the fitting arrangement between the wedge-shaped member 52 and the wedge-shaped cavity 41 not only further prevents the steel sleeve 5 and the drive roller from reversing due to inertial forces, but also ensures that when the worm gear 1 rotates, the steel sleeve 5 and the drive roller inside rotate in small increments, rather than smoothly, thereby improving the output efficiency of the drive roller. It is worth noting that the drive roller has higher output efficiency during small increments; this is existing technology, so the specific principle will not be elaborated further.
[0029] It is worth noting that the drive motor in this application is a low-speed motor, and the transmission speed in this application is all low-speed operation.
[0030] In this invention, the rotation of the worm gear 1 can drive the steel sleeve 5 and the transmission roller to rotate. Through the matching arrangement between the irregular part 51, the wedge part 52 and the fixed ring 4 and the wedge cavity 41, not only can the steel sleeve 5 and the transmission roller rotate in a point rotation manner, but the reverse rotation of the steel sleeve 5 and the transmission roller can also be prevented.
[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
