Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tower bases of fitness equipment, in particular to a lubrication structure of a flywheel tower base. Background Art
[0002] A flywheel freewheel base is typically used in equipment or systems that require inertial rotating parts to provide additional power, balance, or stability. In some fitness equipment, a flywheel freewheel base is used to simulate a real riding feel or provide a higher level of training mode. These devices combine a flywheel and a freewheel base to provide more inertia and motion stability. However, lack of sufficient lubrication when the flywheel rotates at high speed will lead to increased friction between gears, which may increase gear surface wear and shorten the service life of the gears. Insufficient lubrication will also increase friction and vibration between gears, resulting in noise during operation, affecting the user experience of the equipment, and even causing certain dangers. Therefore, in response to the above problems, a lubrication structure for a flywheel freewheel base is proposed. Utility Model Content

[0014] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.
[0015] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0016] Embodiment 1:
[0017] like Figure 1-2As shown, an embodiment of the utility model is provided: a lubrication structure of a flywheel tower base, including a tower base body 1, a plurality of jack teeth 2 are arranged in a circumferential array at the front end of the tower base body 1, and elastic plates 3 are arranged inside the plurality of jack teeth 2, the elastic plates 3 and the jack teeth 2 are abutted against each other, and the elastic plates 3 are used to support the jack teeth 2 so that the jack teeth 2 are always in a state of being opened outward, a plurality of grooves 4 are arranged inside the front end of the tower base body 1, a groove cover 5 is arranged in front of the groove 4, a movable groove 6 is opened inside the groove 4, one end of the movable groove 6 is communicated with the front of the inner side of the groove 4 and is connected with the front jack teeth 2, and the other end penetrates one side of the tower base body 1 and is connected to the inner side of the elastic plate 3, a rotating rod 7 is arranged in the movable groove 6, and the rotating rod 7 is rotatably arranged at the front end of the tower base body 1 through a rotating shaft, And it is arranged on the inner side of the elastic plate 3; a lubrication device 8 that can lubricate the gear 2 is arranged in each of the multiple grooves 4, and the lubrication device 8 includes a spring 81, one end of the spring 81 is arranged on the rear side surface of the groove 4, and a lubricating oil bag 82 is arranged on the other end of the spring 81. The rear end of the rotating rod 7 abuts against the inner side of the elastic plate 3. When the gear 2 is insufficiently lubricated, the pressure on the elastic plate 3 will increase, causing the elastic plate 3 to deform inward, and drive the rotating rod 7 to rotate, so that the front end of the rotating rod 7 moves outward, and the spike 72 pierces the lubricating oil bag 82 to make the lubricating oil flow out through the moving groove 6 to the gear 2, which lubricates the gear 2, reduces the friction between the gear 2 and the elastic plate 3, and makes the rotation process smoother without vibration that affects the use of the fitness equipment.
[0018] Furthermore, the lubricating oil bag 82 is a multi-layer structure, and each layer is relatively sealed. After the front layer of the lubricating oil bag 82 is broken, the rear multi-layer lubricating oil bag 82 can still play a lubricating role, and there is no need to repeatedly disassemble the tower base to replace the lubricating oil bag 82. When the lubricating oil bag 82 is full of oil, one side of the lubricating oil bag 82 contacts the spring 81, and the other side contacts the front side of the groove 4, so that the front layer of the lubricating oil bag 82 is always in the connecting position between the movable groove 6 and the groove 4, so that the rotating rod 7 can puncture the lubricating oil bag 82 every time it rotates. When the lubricating oil bag 82 is not filled with oil, the spring 81 is in a compressed state, and the spring 81 is always in a compressed state. When the front layer of the lubricating oil bag 82 is punctured, the lubricating oil bag 82 can be pushed to move forward to prepare for the next lubrication.
[0019] Furthermore, a baffle 71 and a spike 72 are provided at the front end of the rotating rod 7, and the baffle 71 is provided behind the spike 72. When the rear end of the rotating rod 7 abuts against the inner side of the elastic plate 3, the baffle 71 and the spike 72 do not contact the lubricating oil bag 82, thereby preventing the spike 72 from piercing the lubricating oil bag 82 when the rotating plate is not rotated. When the spike 72 pierces the previous layer of the lubricating oil bag 82 after the rotating plate rotates, the baffle 71 restricts the lubricating oil bag 82 from moving forward, causing each layer of the lubricating oil bag 82 to be pierced.
[0020] Furthermore, the weight of the rotating rod 7 in the movable groove 6 and on the left side of the rotating shaft is greater than the weight of the rotating rod 7 under the spring 81 and on the right side of the rotating shaft. When the friction between the jack tooth 2 and the elastic plate 3 is small, the rear end of the rotating rod 7 is always in contact with the inner side of the elastic plate 3, and the spike 72 will not contact the lubricating oil bag 82, causing the lubricating oil bag 82 to rupture, making it impossible to lubricate the flywheel tower base after running for a long time.
[0021] Working principle: When the fitness equipment is in use, the flywheel tower base is also rotating. When the gear 2 is not lubricated enough, the friction between the gear 2 and the elastic plate 3 increases, and the pressure on the elastic plate 3 also increases. At this time, the elastic plate 3 deforms inward, driving the rotating rod 7 to rotate around the rotating axis. The front end of the rotating rod 7 rotates outward. When the spike 72 touches the lubricating oil bag 82, the spike 72 pierces the front layer of the lubricating oil bag 82, causing the lubricating oil to flow out and flow to the gear 2 through the movable groove 6. At the same time, the baffle 71 prevents the lubricating oil bag 82 from Move forward. At this time, the flywheel tower base is still rotating, so that the lubricating oil can lubricate the jack gear 2 faster. When the friction of the jack gear 2 is reduced, the pressure on the elastic plate 3 is reduced, and the rotating rod 7 returns to its initial position under the action of gravity. The rear end of the rotating rod 7 is still in contact with the inner side of the elastic plate 3, and the baffle 71 is away from the lubricating oil bag 82. The spring 81 pushes the lubricating oil bag 82 to move forward. When the friction between the jack gear 2 and the elastic plate 3 increases again, the above process is repeated until the lubricating oil bag 82 is used up, and the slot cover 5 is opened to replace the lubricating oil bag 82.
[0022] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
