The origin of roller skates is interesting. 1100 年 ，猎人们为了在冬天也能打猎，将骨头装在长皮鞋底 下，算是溜冰鞋 的最早样式。 It is said that as early as 1100 , hunters mounted bones under long leather shoes in order to hunt in the winter , which is the earliest style of skates . 年，一位伦敦乐器制造商乔赛夫 - 马林发明了一双配有轮子的溜冰鞋，轮子很小，金属制成。 In 1760 , a London musical instrument maker, Josef Marin, invented a pair of roller skates with small wheels made of metal. He wore these skates to a masquerade while playing the violin while skating. Although he himself finally fell to the spot, he set a precedent for roller skating. 年，曼西尔 - 彼提博又发明了一种溜冰鞋，以木块做鞋底，下面装轮子，轮子排成一线。 In 1819 , Mancil - Pitibault invented another kind of skates. The soles were made of wooden blocks, with wheels underneath, and the wheels lined up. But because each wheel is different in size, it can only slip forward. 1863 年，美国人詹姆士发明了一双轮子并排的四轮溜冰鞋，可以做转弯、前进和后退的各种动作，这就是现在流传最为广泛的轮滑鞋。 By 1863 , American James invented a pair of side-by-side roller skates, which can perform various actions of turning, forward and backward, this is the most widely used roller skates. - 深沟球嘛？ But do you know the supporting expert of roller skates - deep groove ball? Let's find out:
Deep groove ball bearings can be said to be the big brother of the bearing family. Because of its small friction coefficient, high limiting speed, low manufacturing cost, and easy to achieve high manufacturing accuracy. Therefore, it has become the bearing with the largest output and the most widely used bearing in the bearing family. Almost 100% of the entire bearing world.
Bearings in the traditional sense are mostly related to industry, and it is difficult for us to associate them with the words of leisure and entertainment, sports and fitness. But deep groove ball bearings are different, and its application in extreme sports of roller skating has changed our views.
轮滑鞋中 是放在轮子中间的金属物体，以帮助助轮子的转动。 Deep groove ball bearings are metal objects placed in the middle of the wheels in roller skates to help the wheels turn. Each wheel has a bearing on both sides, separated by a sleeve in the middle. Generally single-row shoes use plastic sleeves, and higher-level ones will use metal sleeves; abec 1 ~ 5 , Level , The higher the level, the more precise it is. The quality of the bearing cannot be relied on abec , 。 To determine the index, the difference between products of different manufacturers is often greater than these indexes .
At the same time, the quality of deep groove ball bearings determines the flexibility of the shoe. A good deep groove ball bearing should have a very smooth appearance and high strength. It seems that the workmanship should be delicate and exquisite, and both bearing covers should have the words of regular model and brand.
In use of deep groove ball bearings, it must be noted that water must not be seen, otherwise it will rust. If there is a lot of sludge on the bearing surface, you can wipe it with a dry cloth or a slightly damp cloth. If you make a sound when you rotate the bearing, it may be rusted, or the steel balls are broken, or there is no oil. Live bearings only need to lift the dust-proof plate and apply some oil; if the steel balls are broken, you need to replace the bearings; Dead bearings cannot be opened and can only be replaced with new ones. If the rotation speed is very slow, there may be a lot of dirt accumulated in the bearing; at this time, the bearing should be cleaned, and a special oily cleaning agent can be used. 10 分钟左右再轻轻摇晃更好的除去污垢，取出后用干布或废纸吸干上面的液体，最后抹上黄油盖上防尘盖就好了。 The method is to put the dust-proof sheet on both sides next, put the cleaning agent in a bottle with a cap (the bottle mouth should be able to fit into the bearing), and then put the bearing into the bottle to seal the cap, soak it in 10 Gently shake it for a few minutes or so to better remove the dirt. After removing it, dry the liquid with a dry cloth or waste paper, and then cover it with butter and dust cover. (Butter is best, but also oil)
Of course, sometimes the surface of the bearing is very dirty, and simple cleaning can not achieve the effect we want, then the bearing needs to be removed and cleaned. Generally, I suggest that you use a hexagonal screwdriver to slowly pry, the force should be evenly distributed, and you can't pry at a single point, so that it will not have much impact on the bearing. After cleaning, it is more convenient to install, so I wo n’t say much here.
Generally do not care about the bearings of roller skates. Pay attention not to slide on wet ground at all, but to slide on smooth ground as much as possible. By then the bearings can be replaced after a long time. It is enough to change one set in about one year.
