摘要： A plurality of retaining grooves for rolling members are arranged in the inner cylinder. The retaining grooves have semicircular bottom halves and top halves having sector-shaped sections diverging radially outwardly. The rolling members are accommodated in the bottom halves of the retaining grooves and grease fills the top halves. Then, the inner cylinder is fit into the outer cylinder. In rotating the bearing, the rolling members are rotated by the bottom halves of the retaining grooves serving as a sliding bearing and rolled on the inner peripheral surface of the outer cylinder. When a heavy load is applied, the rolling members are pushed down to the same level as the outer peripheral surface of the inner cylinder, thereby distributing and supporting the load by the outer peripheral surface of the inner cylinder and the rolling members. Therefore, the present invention can provide a roller bearing which is made compact by omitting the retainer for the rolling members and which exhibits good lubrication performance and endurance, avoiding vibration and noises.
摘要翻译：多个用于滚动构件的保持槽布置在内筒中。保持槽具有半圆形的下半部分和顶部半部，其具有径向向外发散的扇形部分。滚动构件容纳在保持槽的下半部分中，并且润滑脂填充上半部分。然后，内筒装配到外筒中。在旋转轴承时，滚动部件被作为滑动轴承的保持槽的下半部旋转，并在外筒的内周面上滚动。当施加重负荷时，滚动体被压下到与内筒的外周面相同的高度，从而通过内筒和滚动体的外周面进行负荷的分配和支撑。因此，本发明可以提供一种滚动轴承，其通过省略用于滚动部件的保持器而制造得紧凑，并且具有良好的润滑性能和耐久性，避免了振动和噪声。

摘要： One or two submarine gates 23 are located at portions of a mold corresponding to one or both ends of a tip seal to be molded. Synthetic resin is injected through the submarine gates 23. When the mold is opened after the synthetic resin is solidified, a molded product is cut off and separated by shearing from a runner 22 at a tip 23a of each of the submarine gates 23. Thus, no convex portion is formed as a gate trace on the end of the tip seal as a molded product when it is cut off. When the tip seal having no convex portion on the end thereof is inserted into the mounting groove of a scroll type compressor, the tip seal exhibits an excellent sealing property. With the aforesaid method, a tip seal excellent in a sealing property can be easily manufactured.
摘要翻译：一个或两个潜艇闸门23位于与要模制的尖端密封件的一端或两端对应的模具的部分处。合成树脂通过海底闸门23注入。当合成树脂固化后打开模具时，通过剪切从模具22中切出并分离模制产品，并从每个潜艇闸门23的尖端23a处的流道22分离。因此，在切断时，作为模制品，在尖端密封件的端部上没有形成凸起部分作为浇口痕迹。当其末端没有凸起部分的末端密封件插入到涡旋式压缩机的安装槽中时，尖端密封件具有优异的密封性能。通过上述方法，可以容易地制造密封性优异的尖端密封。
