For the person skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances. The embodiments will be described below according to the overall structure of the present application.
[0029] Referring to Figure 1 The embodiments of the present application provide a split bearing, which comprises:
[0030] The inner ring part 1;
[0031] The outer ring part 2 is sleeved on the inner ring part 1, and the retainer 3 is installed between the outer ring part 2 and the inner ring part 1;
[0032] The retainer 3 has a first side 31 facing the inner ring part 1, and has a second side 32 facing the outer ring part 2, the first side 31 abuts against the inner ring part 1, and the second side 32 abuts against the outer ring part 2, a plurality of mounting holes 33 are formed on the retainer 3, a rolling body 34 is installed in any mounting hole 33, and the rolling body 34 abuts against the inner ring part 1 and the outer ring part 2;
[0033] Among them, the first side 31 and the second side 32 are provided with an inclined surface part 35, and the inclination angle of the inclined surface part 35 is 45 degrees.
[0034] According to Figure 1The skilled in the art can set the split bearing to include the inner ring part 1, the outer ring part 2 and the cage 3. It can be understood that the inner ring part 1 and the outer ring part 2 can be connected by the setting of the cage 3.
[0035] Specifically, the cage 3 has a first side 31 and a second side 32. The first side 31 is the side of the cage 3 facing the inner ring part 1, and the second side 32 is the side of the cage 3 facing the outer ring part 2. In this embodiment, the skilled in the art can set the first side 31 of the cage 3 to abut the inner ring part 2, and the second side 32 to abut the outer ring part 1.
[0036] The skilled in the art can set a plurality of mounting holes 33 on the cage 3, and each of the mounting holes 33 is mounted with a rolling body 34. That is, the skilled in the art can set the rolling body 34 to abut the inner ring part 1 and the outer ring part 2, so as to complete the setting of the split bearing structure.
[0037] Further, the skilled in the art can set a bevel part 35 between the first side 31 and the second side 32, and the inclination angle of the bevel part 35 is 45 degrees.
[0038] According to the above structure, the skilled in the art can set the bevel part 35 between the first side 31 and the second side 32 to have a contact angle of 45 degrees. According to the above structure, Figure 3 The cage 3 can be set as a conical ring. That is, the thickness between the second side 32 and the first side 31 is linearly increased, so as to effectively bear the torque in the connected structure.
[0039] In summary, the skilled in the art can set the bevel part 35 in the cage 3 of the split bearing to have a contact angle of 45 degrees, so as to make the relative structure of the inner ring part 1, the outer ring part 2 and the cage 3 more stable, and further make the split bearing bear a larger torque.
[0040] In the above structure, it can be understood that the first side 31 abuts the inner ring part 1, and the second side abuts the outer ring part 2. The rolling body 34 rolls against the inner ring part 1 and the outer ring part 2, so as to make the bearing bear a larger axial force.
[0041] In an alternative embodiment, preferably, a plurality of oil storage grooves are formed on the cage 3 for storing oil. That is, the skilled in the art can form the oil storage grooves on the cage 3 to store oil, so as to make the bearing be fully immersed in the lubricating oil during use.
[0042] It can be understood that the structure of the above-mentioned oil storage groove for storing oil can not only form a stable oil film on the bearing internal parts, but also avoid damage to the parts under the action of extrusion.
[0043] Through the above structure, a person skilled in the art can open multiple oil storage grooves on the retainer 3, and the multiple oil storage grooves are uniformly spaced. More preferably, any oil storage groove has a depth of 0.5 mm.
[0044] Preferably, the multiple oil storage grooves are uniformly distributed. That is, the multiple oil storage grooves are uniformly spaced, and the size and depth of the multiple oil storage grooves are the same, so that the retainer 3 can uniformly store oil.
[0045] In summary, a person skilled in the art can set multiple oil storage grooves on the retainer 3, and the multiple oil storage grooves are uniformly spaced, and the size and depth of the multiple oil storage grooves are the same, so that the retainer 3 can uniformly store oil, and the working state of the split bearing can be more stable.

In a specific arrangement, the split bearing is sleeved on the outer wall of the output shaft, and the outer ring part 2 of the split bearing is in contact with the housing. That is, in the present embodiment, a person skilled in the art can set the split bearing between the output shaft and the housing of the harmonic reducer.
[0047] Through the above structure, by setting the split bearing between the output shaft and the housing, the output shaft of the harmonic reducer can stably output power.
[0048] In an alternative embodiment, preferably, multiple split bearings are sleeved on the outer wall of the output shaft. That is, in the present embodiment, a person skilled in the art can position the parts mounted on the output shaft through multiple split bearings, and also stably connect the housing and the output shaft.
