Description

Technical Field

[0001] The utility model relates to the technical field of belt locking, in particular to a belt locking bolt for a stirring speed reducer. Background Technique

[0002] The open belt can better adapt to high acceleration, speed bumps and continuous high-speed rotation work. Compared with the traditional belt, the open belt can be better applied to the internal transmission work of the stirring speed reducer. When the common open belt on the market is installed, it is necessary to first dock the docking ports at both ends of the open belt and align the threaded holes on the docking ports, and then use bolts to screw into the threaded holes to complete the fixation. However, the conventional bolt only has the function of screwing and fixing. When the open belt is working, it is easy to generate vibration, which will cause the bolt to loosen, thus affecting the locking effect of both ends of the open belt. In view of the above situation, technical innovation is carried out on the basis of the existing belt locking bolt for the stirring speed reducer. Content of the Utility Model

[0003] The purpose of the utility model is to provide a belt locking bolt for a stirring speed reducer to solve the problems put forward in the above background technique.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 , a belt locking bolt for a stirring speed reducer, including a cross bolt 2. A magnetic ring 33 is fixedly arranged on the outer circle of the screw rod of the cross bolt 2. A bearing 32 is fixedly arranged on the outer circle of the magnetic ring 33 through an adhesive. A pressing ring 3 is fixedly arranged on the outer circle of the bearing 32 through an adhesive. The top of the pressing ring 3 is in contact with the bottom of the screw head of the cross bolt 2. The bottom of the pressing ring 3 is fixedly provided with fixing cones 31 in a circular array. An open belt 1 is placed outside the cross bolt 2. The left end of the open belt 1 is designed as a convex shape, and the right end of the open belt 1 is designed as a concave shape. The left end of the open belt 1 is inserted into the right end of the open belt 1. The top of the right end of the open belt 1 is evenly provided with counterbores. The bottom of the inner side wall of the right end of the open belt 1 is evenly provided with mounting holes. The top of the left end of the open belt 1 is evenly provided with through holes. The through holes are located between the counterbores and the mounting holes and are aligned with each other. A first metal internal thread sleeve 21 is fixedly arranged in the counterbore through an adhesive. A second metal internal thread sleeve 22 is fixedly arranged in the through hole through an adhesive. A third metal internal thread sleeve 23 is fixedly arranged in the mounting hole through an adhesive. The cross bolt 2 is screwed into the first metal internal thread sleeve 21, the second metal internal thread sleeve 22, and the third metal internal thread sleeve 23. The open belt 1 is sleeved on the driving pulley and the driven pulley in the stirring speed reducer, and the left end of the open belt 1 is inserted into the right end of the open belt 1. At this time, the cross bolt 2 is screwed into the first metal internal thread sleeve 21, the second metal internal thread sleeve 22, and the third metal internal thread sleeve 23, so as to dock and lock the left and right ends of the open belt 1. When the cross bolt 2 is tightened, the magnetic ring 33 uses its own magnetic force to magnetically attract the first metal internal thread sleeve 21, and then fixes the cross bolt 2 on the top of the first metal internal thread sleeve 21, thus completing the preliminary fixation of the cross bolt 2. At the same time, when the cross bolt 2 is tightened, the bearing 32 can ensure that the cross bolt 2 does not drive the pressing ring 3 to rotate when rotating. Therefore, when the cross bolt 2 rotates and moves downward, it will drive the pressing ring 3 to move downward synchronously, and then drive the fixing cones 31 at the bottom of the pressing ring 3 to insert into the bottom of the counterbore of the right end of the open belt 1, so as to further reinforce the cross bolt 2. The bottom of the magnetic ring 33 is adsorbed to the top of the first metal internal thread sleeve 21, the bottom of the pressing ring 3 is in contact with the bottom of the counterbore of the counterbore, and the fixing cones 31 are inserted into the bottom of the counterbore of the right end of the open belt 1.

[0021] Working principle: The open belt 1 is sleeved on the driving pulley and the driven pulley in the stirring speed reducer, and the left end of the open belt 1 is inserted into the right end of the open belt 1. At this time, the cross bolt 2 is screwed into the first metal internal thread sleeve 21, the second metal internal thread sleeve 22 and the third metal internal thread sleeve 23, so as to butt and lock the left and right ends of the open belt 1. When the cross bolt 2 is tightened, the magnetic ring 33 uses its own magnetic force to magnetically attract the first metal internal thread sleeve 21, and then fixes the cross bolt 2 on the top of the first metal internal thread sleeve 21, thus completing the preliminary fixation of the cross bolt 2. At the same time, when the cross bolt 2 is tightened, the bearing 32 can ensure that the cross bolt 2 will not drive the pressure ring 3 to rotate when rotating. Therefore, when the cross bolt 2 rotates and moves downward, it will drive the pressure ring 3 to move downward synchronously, and then drive the fixing cone 31 at the bottom of the pressure ring 3 to insert into the bottom of the counterbore groove of the counterbore in the right end of the open belt 1, so as to further reinforce the cross bolt 2, and thus effectively reduce the occurrence of bolt loosening caused by the vibration of the open belt when the stirring speed reducer works.
