Description

DETAILED DESCRIPTION OF THE INVENTION                          Rolling bearing for reciprocating motion   The present invention relates to a rolling bearing applied to a reciprocating mechanical device, and particularly to an angular direction. The present invention relates to a rolling bearing having a vibrating race for reciprocating movement.   When such a rotating race experiences vibrations under load, it will wear out Rolling bearings are destroyed by corrosion.   When these repetitive vibrations are applied to the race, the quality of the lubrication changes, The mixture of the agent and the iron oxide generated during vibration causes the rolling bearing members It has been confirmed to have a destructive wear effect.   In this case, the life of the rolling bearing is significantly shortened.   To solve such a problem, rolling into the groove closed by the closing device Rolling bearings having rolling objects provided adjacent to each other in contact with the track are produced. Was.   In French patent publication FR-A-2,619,606, a groove is formed in the outer race, Adjacent to the race so that the different parts of the race retain their circular shape Rolling bearings that reconnect radial surfaces to mount rolling objects Have been. However, this solution may not always work in certain applications. Not satisfactory.   The present invention is advantageously applicable in the textile industry, meets currently valid standards, The purpose is to provide a rolling bearing that can extend the life and does not require large dimensional changes I do.   The present invention further provides an outer race which is divided and whose divided end faces are adjacent to each other; Rolling races formed in the inner race concentric with the base race and the outer race and the inner race. A road and a plurality of rolling objects disposed in contact with the rolling track. The rolling bearing between the inner race, the outer race and the rolling object. The aim is to provide a rolling bearing characterized in that the internal space is filled with a lubricant. Target.   According to the present invention, the internal space of the rolling bearing is formed by a ring made of a known lubricant. And is opened in contact with the side surface of the rolling bearing, allowing the rolling object to be in contact with the rolling track. An annular chamber is formed in which the lubricant covers the vicinity of the contact point.   Due to the vibration effect of at least one of the outer race and the inner race of the rolling bearing, The body lubricant covers the rolling object up to the vicinity of the contact point with the rolling track. In this way, if at least one of the outer race and the inner race vibrates, Lubrication is performed, and a corrosion phenomenon due to insufficient lubrication can be avoided.   In this way, the solid lubricant and each rolling object are kept in contact with each other, and The grease-like lubricant caused by the contact pressure of the rolling bearing is not discharged.   According to another feature of the invention, a ring comprising a side face of a rolling bearing and a lubricant The rolling bearing's lubricant holding capacity and foreign matter (fines) Water and water) is improved.   Other features and advantages of the present invention will be described with reference to the accompanying drawings. Will be apparent from reading.   FIG. 1 is a front view of the rolling bearing.   FIG. 2 shows a ring of lubricant and a rolling object under load, 1 is an enlarged view of a portion A of FIG.   FIG. 3 shows an embodiment of a ring made of a lubricant.   FIG. 4 is an enlarged view of a contact portion between a ring made of a lubricant and a rolling object.   FIG. 5 is a front view of an embodiment of a rolling bearing having a retainer for a rolling object.   As shown in FIGS. 1-3 and 5, a rolling bearing having a rolling object 3 is an outer race. 1 and an inner race 2. Outer race 1 and inner race 2 are provided concentrically And is supported by the outer race 1 and the inner race 2 so that the rolling tracks 5e and 5i The area of the annular space for receiving the contacting rolling object 3 is limited.   The outer race 1 and the inner race 2 are formed in an annular shape. And receives a radial load F toward the rotation axis.   The rolling bearing is assembled, for example, as follows.   The outer race 1 is split, and the split end face 6a and the split end face 6b Rolling object 3 is attached between outer race 1 and inner race 2 by pulling apart You. Next, the divided end face 6a and the divided end face 6b are brought closer to each other so that they are not disassembled. To   Rolling bearings should be placed horizontally and pre-mounted on a removable, leak-free support , Rotate around a vertical axis.   The solidified oil and liquid phase resin is in contact with the upper surface 12 of the rolling bearing. A certain amount of the lubricant 10 corresponding to the oxidized mixture is injected.   The rolling bearing is then closed using a suitable tool.   Next, the overall temperature of the tool closing the rolling bearing and the rolling bearing is measured by a lubricant. To a temperature at which is transferred to the solid phase.   After cooling, the tool closing the rolling bearing is removed from the rolling bearing.   The number and size of the rolling objects 3 and the shape of the inner and outer races are determined by dynamic and static loads. Optimum so that the capacity of the rolling bearing against increases.   In this way, the internal space V of the rolling bearing filled with the lubricant 10 is located on the side of the rolling bearing. An annular chamber that opens in contact with the surface 12 is formed.   By applying the lubricant 10 as described above, the retention of the lubricant and the rolling bearing Avoid the use of additional sealing measures necessary to prevent the entry of impurities and liquids into the Can be   According to another feature of the invention, the internal space V of the rolling bearing is made of a lubricant. Rolling bearings filled with solid rings Protection is guaranteed.   However, the retention of impurities and other contaminants on the side of the lubricant ring It is also possible to form a deflection surface, which can avoid
