Description

Technical Field

[0001] The invention relates to the technical field of tools for assembling propeller blade bearings, and more particularly to an assembly tool for an outer ring of a propeller blade bearing and a retaining frame support. Background Art

[0002] When assembling the existing propeller blade 100, it is necessary to use the sealing assembly 200 to seal at the corresponding sealing position. After the sealing assembly 200 is assembled, the pressed retainer support 300 and the bearing outer ring 400 are assembled to the blade 100, and the subsequent blade assembly work is completed. The structural schematic diagram is shown in FIG. Figure 1 shown.

[0003] When assembling the bearing outer ring 400 and the retainer support 300, due to the special structure of the sealing assembly 200, the open end of the sealing assembly 200 and the bearing outer ring 400 are interference fit, and since the bearing inner ring 500 is often placed unevenly when assembled on the blade 100, it is difficult to assemble the bearing outer ring 400 onto the blade 100, and when the bearing outer ring is pushed toward the sealing assembly, the uneven placement of the bearing inner ring causes the bearing outer ring to have the risk of cutting the sealing assembly. Therefore, when the existing bearing outer ring and retainer support are assembled on the blade, there is a risk of difficult assembly, low assembly efficiency, and cutting the sealing assembly. In addition, there is no report on the special assembly tooling for the bearing outer ring and retainer support in the prior art.

[0004] Therefore, how to provide an assembly tool for the bearing outer ring and retainer support of a propeller blade that is easy to assemble to the blade, increases the convenience and efficiency of assembly, and avoids damage to the sealing component is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0005] In view of this, the present invention provides an assembly tool for the bearing outer ring and retainer support of a propeller blade, which is easy to assemble the bearing outer ring and retainer support onto the blade, increases the convenience and efficiency of assembly, and avoids damage to the sealing component.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0007] An assembly tool for a bearing outer ring and a retainer support of a propeller blade, comprising:

[0008] An outer sleeve snap ring, wherein a first ring hole of the outer sleeve snap ring is sleeved on the blade, and a first clamping groove coaxially arranged with the first ring hole is formed on the inner side surface of the outer sleeve snap ring, and the first clamping groove is clamped and matched with a first step on the blade;

[0009] The retainer support snap ring is arranged at an interval from the outer sleeve snap ring, and the two are connected by a plurality of evenly arranged first connecting screws, the second ring hole of the retainer support snap ring is sleeved on the retainer support, and a second groove coaxially arranged with the second ring hole is provided on the inner side surface of the retainer support snap ring close to the outer sleeve snap ring, and the second groove is snap-fitted with the second step on the retainer support.

[0010] It can be known from the above technical scheme that, compared with the prior art, the present invention discloses an assembly tool for the bearing outer ring and retainer support of a propeller blade. When in use, the outer sleeve clamping ring is firstly sleeved on the blade using the first ring hole thereon, and the first groove on the outer sleeve clamping ring is snap-fitted with the first step on the blade, and then the press-fitted bearing outer ring and retainer support are sleeved on the blade. At this time, except for the installation position of the bearing outer ring, the bearing outer ring and retainer support are clearance-fitted with other positions on the blade, so that it is easy for the bearing outer ring and retainer support to move on the blade, and then the retainer support clamping ring is snap-fitted with the retainer support. The second ring hole is sleeved on the retainer support, and the second groove on the retainer support snap ring is engaged with the second step on the retainer support, and then the outer sleeve snap ring and the retainer support snap ring are connected with multiple first connecting screws, and then the multiple first connecting screws are tightened evenly, so that the retainer support snap ring moves in the direction close to the outer sleeve snap ring, and then the retainer support snap ring drives the retainer support and the bearing outer ring to be evenly pushed in the direction close to the outer sleeve snap ring until the retainer support and the outer sleeve snap ring are installed in place, and then the first connecting screw is removed, and the outer sleeve snap ring and the retainer support snap ring are removed for later assembly. Therefore, the assembly tool is used in conjunction with the first step and the second step, and the first connecting screw is tightened evenly, which can evenly push the bearing outer ring and the retainer support, increase the stability and convenience of assembly, avoid damage to the sealing component, and facilitate the assembly of the bearing outer ring and the retainer support, and can improve the assembly efficiency of the bearing outer ring and the retainer support.

[0011] Furthermore, the outer sleeve retaining ring includes: a first half ring and a second half ring that are detachably connected, the first half ring having a first half ring hole and a first half groove, the second half ring having a second half ring hole and a second half groove, when the first half ring and the second half ring are matched, the first half ring hole and the second half ring hole are matched to form the first ring hole, and the first half groove and the second half groove are matched to form the first groove.

[0012] Furthermore, the first half ring and the second half ring are detachably connected via a second connecting screw.

[0013] The beneficial effect of adopting the above technical solution is that the outer sleeve clamping ring is divided into a first half ring and a second half ring, so that when installing the outer sleeve clamping ring, it is only necessary to assemble the first half ring and the second half ring onto the blade, and then fix it with the second connecting screw. Compared with the installation method of the set, the outer sleeve clamping ring is easier to assemble onto the blade.

[0014] Furthermore, a screw insertion hole is opened on the outer wall of the first half ring, and a connecting hole is opened on the outer wall of the second half ring. A wire screw sleeve is fixed in the connecting hole, and the screw rod of the second connecting screw passes through the screw insertion hole and is threadedly connected to the wire screw sleeve.

[0015] The beneficial effect of adopting the above technical solution is: by arranging a wire screw sleeve in the connecting hole, there is no need to process threads in the connecting hole, thereby avoiding the problem of increased material costs caused by replacing the second half ring when thread slippage occurs during processing threads in the connecting hole.
