[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Embodiment 1
[0022] like Figure 1-4 As shown, the utility model provides a large torque worm gear reducer, including a protective shell 1, a transmission mechanism 2 is arranged inside the protective shell 1, the transmission mechanism 2 includes a worm body 22 and a worm wheel body 23, a lubrication mechanism 3 is arranged above the worm wheel body 23, the lubrication mechanism 3 includes an oil storage pipe 31 and a fixed plate 34, a plurality of groups of limit strips 32 are fixedly installed on the outer wall of the oil storage pipe 31, a ball 33 is arranged inside the oil storage pipe 31, an oil through port 35 is fixedly installed on the top of the oil storage pipe 31, a limit rod 36 is penetrated inside the fixed plate 34, a threaded rod 37 is threadedly connected inside the fixed plate 34, a plurality of groups of limit strips 32 are arranged inside the protective shell 1, the outer wall of the oil storage pipe 31 is slidably connected to the inner wall of the protective shell 1, the outer wall of the ball 33 is in contact with the inner wall of the oil storage pipe 31, the oil storage pipe 31 is penetrated and installed inside the fixed plate 34, the bottom of the limit rod 36 is fixedly connected to the top of the protective shell 1, and the bottom of the threaded rod 37 is rotatably connected to the top of the protective shell 1.
[0023] The following is a detailed description of the specific settings and functions of this embodiment. When the reducer is used and the worm body 23 and the worm body 22 need to be lubricated, first pour lubricating oil from one end of the oil passage 35, and the lubricating oil enters the interior of the oil storage tube 31. Then the staff inserts the hexagonal bolt into the top of the threaded rod 37, and then manually rotates the threaded rod 37 to make the fixing plate 34 move downward along the limiting rod 36, and then the fixing plate 34 drives the oil storage tube 31 to move downward. The multiple groups of limiting bars 32 limit the oil storage tube 31 to move only in the vertical direction. When the oil storage tube 31 moves downward, it drives the ball 33 downward together until the ball 33 moves to the top of the worm wheel body 23. Since the outer wall of the worm wheel body 23 has a concave and convex texture, the position of the ball 33 is where the convex texture of the worm wheel body 23 can touch it, but the outer wall of the worm wheel body 23 cannot touch the bottom of the oil storage tube 31. By setting the lubrication mechanism 3, the outer wall of the ball 33 and the oil storage tube 31 are originally The inner wall of the worm gear body 23 is in close contact, and the oil inside the oil storage tube 31 will not leak. During the rotation of the worm gear body 23, the raised texture will touch the lifting ball 33, lifting the ball 33 a short distance, thereby causing a gap between the outer wall of the ball 33 and the inner wall of the oil storage tube 31, allowing the lubricating oil to leak out of the gap and leak to the outer wall of the worm gear body 23. During the rotation of the worm gear body 23, the lubricating oil attached to the outer wall will be stained to the outer wall of the worm body 22, thereby lubricating the outer walls of the worm body 22 and the worm gear body 23. The lubrication mechanism 3 can effectively reduce the friction between the worm gear body 23 and the worm body 22, and the good state of the reducer parts, ensure the stability of the transmission efficiency and improve the performance of the equipment, reduce energy loss, and improve the transmission efficiency. The position of the ball 33 can also be adjusted according to actual use requirements, so that the gap between the ball 33 and the oil storage tube 31 when it is lifted can be adjusted, thereby changing the speed of oil leakage. Embodiment 2
[0024] like Figure 1 and Figure 2 As shown, one side of the protective shell 1 is rotatably connected with an input shaft 21, and a worm body 22 is fixedly installed on the outer wall of the input shaft 21. The outer wall of the worm body 22 meshes with the outer wall of the worm wheel body 23, and one side of the worm wheel body 23 is rotatably connected with the inner wall of the protective shell 1. An output shaft 24 is fixedly installed on one side of the worm wheel body 23, and one end of the output shaft 24 is rotatably connected with the inner wall of the protective shell 1. A gear 27 is fixedly installed on the outer wall of the input shaft 21, and a gear 1 26 meshes with the outer wall of the gear 27. A transmission shaft 25 is installed through the interior of the gear 1 26, and one end of the transmission shaft 25 is rotatably connected with the interior of the protective shell 1.
[0025] The effect achieved by the entire embodiment is that when using the reducer, the input shaft 21 and the output shaft 24 can be connected according to the use requirements, and the worm body 22 and the worm wheel body 23 can be used for deceleration. The motor can also be connected to one end of the transmission shaft 25 so that gear one 26 drives gear two 27 to rotate. By setting gear one 26 and gear two 27, since the number of teeth of gear one 26 is less than the number of teeth of gear two 27, the deceleration effect is achieved with the cooperation of gear one 26 and gear two 27. Therefore, according to actual use requirements, the motor output position can be connected to one end of the input shaft 21 and the transmission shaft 25, so as to achieve different deceleration effects and meet the use requirements of multi-stage deceleration.
[0026] The usage and working principle of this device: When using the reducer, you can choose to connect the input shaft 21 and the output shaft 24 according to the usage requirements, use the worm body 22 and the worm wheel body 23 to reduce speed, or you can connect the motor to one end of the transmission shaft 25 so that gear 1 26 drives gear 2 27 to rotate. Since the number of teeth of gear 1 26 is less than the number of teeth of gear 27, the cooperation of gear 1 26 and gear 2 27 can achieve the effect of reducing speed. Therefore, according to actual usage requirements, the motor output position can be connected to one end of the input shaft 21 and the transmission shaft 25. When the worm wheel body 23 and the worm body 22 need to be lubricated, first pour lubricating oil from one end of the oil port 35, and the lubricating oil enters the interior of the oil storage pipe 31. Then the staff uses the hexagonal bolt to insert the top of the threaded rod 37, and then manually rotates the threaded rod 37 to make the fixed plate 34 move downward along the limit rod 36, and then the fixed plate 34 drives the oil storage The tube 31 moves downward, and the multiple groups of limit bars 32 limit the oil storage tube 31 to move only in the vertical direction. When the oil storage tube 31 moves downward, the ball 33 is driven downward together until the ball 33 moves to the top of the worm gear body 23. Since the outer wall of the worm gear body 23 has a concave-convex texture, the position of the ball 33 is where the convex texture of the worm gear body 23 can touch it, but the outer wall of the worm gear body 23 cannot touch the bottom of the oil storage tube 31. Originally, the outer wall of the ball 33 is in close contact with the inner wall of the oil storage tube 31, and the oil inside the oil storage tube 31 will not leak. During the rotation of the worm gear body 23, the convex texture will touch and lift the ball 33, lifting the ball 33 a short distance, thereby causing a gap between the outer wall of the ball 33 and the inner wall of the oil storage tube 31, causing the lubricating oil to leak out of the gap to the outer wall of the worm gear body 23, and during the rotation of the worm gear body 23, the lubricating oil attached to the outer wall will be stained to the outer wall of the worm body 22.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
