Description

Technical Field

[0001] The utility model relates to the technical field of bearing protection, in particular to a packaging tool for preventing bearing parts from being damaged by bumps and collisions. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. According to the different friction properties of the moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings, their radial dimensions, vibrations and noise are larger, and their prices are also higher. Rolling bearings generally consist of four parts: outer ring, inner ring, rolling element, and cage. Strictly speaking, they consist of six parts: outer ring, inner ring, rolling element, cage, seal, and lubricating oil. In short, as long as they have outer ring, inner ring, and rolling element, they can be defined as rolling bearings. According to the shape of the rolling element, rolling bearings are divided into two categories: ball bearings and roller bearings. When packaging bearing parts, packaging boxes are needed for safety protection.

[0003] In the prior art, the Chinese patent document with application number: 201720647281.9 discloses a bearing packaging box, including a box body, both sides of the inner cavity of the box body are fixedly connected with a shell, the inner wall of the shell is fixedly connected with a spring, one end of the spring away from the inner wall of the shell is fixedly connected with a limit plate, the top and bottom of the limit plate away from the end of the spring are fixedly connected with a slide bar, the end of the slide bar away from the limit plate penetrates to the outside of the shell and is fixedly connected with a positioning plate, and the side of the positioning plate away from the slide bar is provided with a positioning groove. The utility model solves the problem that the existing bearing packaging box cannot position the bearing and easily causes the bearing to shake by setting the box body, the shell, the positioning groove, the positioning column, the limiting plate, the spring, the box cover, the sliding rod, the positioning plate and the anti-slip pad. The bearing packaging box has the advantages of being able to position the bearing and preventing the bearing from shaking randomly, thereby improving the practicality of the existing bearing packaging box and is worthy of promotion.

[0004] However, since the above technical solution only relies on the elastic force of the spring to clamp the bearing, when the box is bumped, the box will apply the impact force to the spring and cause the spring to vibrate and deform. At this time, it is difficult for the positioning plate to stably clamp the bearing, causing the bearing to shake unstably inside the box, and even cause damage to the bearing, and the protection effect of the bearing cannot be guaranteed. For this reason, we propose a packaging tool that prevents bearing parts from being bumped and damaged to solve the above problem. Utility Model Content
