Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
For the convenience of understanding the retainer of the cylindrical roller bearing provided by the embodiments of the present invention, the following detailed description will be made with reference to the accompanying drawings and specific embodiments.
Please refer to fig. 1-5 together, fig. 1 is a schematic structural diagram of a cylindrical roller bearing's holder when being installed between a bearing outer ring and a bearing inner ring, fig. 2 is a schematic structural diagram of the cylindrical roller bearing's holder when being removed from the bearing outer ring in fig. 1, fig. 3 is a schematic structural diagram of the cylindrical roller bearing's holder provided by the embodiment of the present invention's half-section in fig. 1, fig. 4 is a plan view of the cylindrical roller bearing's holder when being installed between the bearing outer ring and the bearing inner ring, fig. 5 is a partial enlarged view of a point in fig. 4 provided by the embodiment of the present invention.
As shown in fig. 1-5, the cage of the cylindrical roller bearing includes a cage 3 disposed between a bearing outer ring 1 and a bearing inner ring 2, a plurality of pockets 4 are disposed on the cage 3, and rolling elements 5 are disposed inside the pockets 4.
In addition, oil injection cavities 6 are formed in the retainer 3 between the adjacent pockets 4, and oil injection ports 7 communicated with the oil injection cavities 6 are formed in the top of the retainer 3. The cross section of the oil injection cavity 6 is trapezoidal, so that the oil injection cavity 6 has a large oil storage space, and after lubricating oil is thrown to the side wall of the oil injection cavity 6, the lubricating oil can quickly slide off the inclined inner wall of the oil injection cavity 6 and be gathered again under the action of gravity, so that oil adhesion on the side wall of the oil injection cavity 6 can be effectively reduced, and the oil storage effect of the oil injection cavity 6 is effectively guaranteed.
Besides, a needle roller pocket hole 8 is formed in the side wall adjacent to any oil injection cavity 6 and the pocket hole 4, the needle roller pocket hole 8 is communicated with the adjacent oil injection cavity 6 and the pocket hole 4, the structure of the needle roller pocket hole 8 is the same as that of the pocket hole 4, the needle roller pocket hole 8 is smaller than the inner cavity height of the oil injection cavity 6, needle rollers 9 are arranged inside the needle roller pocket hole 8, and the needle rollers 9 are in line contact with rolling bodies 5 inside the adjacent pocket hole 4.
The rolling bodies 5 and the roller pins 9 are cylindrical, the rolling bodies 5 and the roller pins 9 are made of GCr15 steel, and the GCr15 steel is high in strength and excellent in wear resistance, so that the rolling bodies 5 and the roller pins 9 have the capacity of bearing strong impact loads, and the service lives of the rolling bodies 5 and the roller pins 9 are greatly prolonged. The needle roller 9 is in close contact with the rolling element 5, and when the rolling element 5 rotates, the needle roller 9 also rotates. The rolling body 5 and the roller pin 9 are in rolling contact in the working process, sliding friction contact between the rolling body 5 and the pocket 4 is reduced, and the effects of small starting torque and small rolling friction coefficient are achieved.
Before the bearing uses, lubricating oil accessible oiling mouth 7 pours into and annotates oil pocket 6 inside and store, when the bearing uses, along with rolling element 5's roll, under centrifugal force, the lubricating oil of storing in annotating oil pocket 6 inside can constantly be got rid of to the lateral wall in oiling chamber 6, because rolling element 5 and kingpin 9 are at the in-process journey rolling contact state, when rolling element 5 revolves, kingpin 9 also revolves, can carry out even lubrication to rolling element 5 surface through setting up kingpin 9 and the contact of rolling element 5 inside in kingpin pocket hole 8 like this, the lubrication effect has been promoted greatly, can also effectively avoid lubricating oil to run off, make rolling element 5 can obtain effective lubrication all the time, when taking place the friction between rolling element 5 and the pocket hole 4, be difficult for arousing the noise and generate heat, thereby avoid damaging holder 3, cylindrical roller bearing's life has been prolonged greatly.
