In order to make the technical field of the present invention better understand, the present invention will be described in detail with reference to the accompanying drawings and the detailed description.
The embodiment of the utility model provides a pivot subassembly, as shown in description attached figure 2 and figure 3, including first pivot 1, support piece 4, second pivot 7, first fastening portion 11 and second fastening portion 8. The first rotating shaft 1 and the second rotating shaft 7 are respectively located at two sides of the supporting member 4, the first fastening portion 11 fixes the first rotating shaft 1 and the supporting member 4, and the second fastening portion 8 fixes the second rotating shaft 7 and the supporting member 4.
The first and second rotating shafts 1 and 7 may have the same structure and size, and the first and second fastening parts 11 and 8 may have the same structure and size, so that the first and second rotating shafts 1 and 7 are symmetrically disposed at both sides of the supporting member 4, and the first and second fastening parts 11 and 8 are also symmetrically disposed.
The first fastening part 11 and the second fastening part 8 can be specifically fasteners such as bolts, the first rotating shaft 1 and the second rotating shaft 7 can be provided with through holes penetrating through two ends in the axial direction, the supporting piece 4 is provided with threaded holes matched with the through holes, in the assembling process, the tail ends of threaded columns of the bolts penetrate through the through holes and are screwed into the threaded holes, and the heads of the bolts are abutted against the end faces of the through holes, so that connection can be realized; of course, the first fastening portion 11 and the second fastening portion 8 may also be specifically a screw or the like, and the assembling manner thereof is similar to that described above, and is not described herein again.
The specific shape and structure of the first rotating shaft 1 and the second rotating shaft 7 can be determined according to actual needs, the first rotating shaft and the second rotating shaft can be generally cylindrical, the supporting member 4 can be arranged to be vertical, and when the first rotating shaft 1 and the second rotating shaft 7 rotate synchronously, the supporting member 4 can be driven to swing back and forth, so that the pitching angle of the supporting member 4 can be adjusted.
In order to optimize the shape and the structure of the first rotating shaft 1 and the second rotating shaft 7, as shown in fig. 2 to fig. 4 of the specification, the first rotating shaft 1 and the second rotating shaft 7 are provided with an inner cavity 103, the opening of the inner cavity 103 faces to one end far away from the support member 4, one side of the inner cavity 103 close to the support member 4 is provided with a mounting hole 104, and the support member 4 is provided with a mounting hole 403.
Obviously, the mounting hole 104 should be a through hole, and the mounting hole 104 and the assembly hole 403 may be coaxially arranged; taking the attached fig. 4 as an example, when the first rotating shaft 1 and the supporting member 4 need to be fixed, the first fastening portion 11 is extended into the inner cavity 103, so that the tail portion of the first fastening portion 11 penetrates through the mounting hole 104 and extends into the assembling hole 403, thereby realizing the connection between the first rotating shaft 1 and the supporting member 4.
Continuing with the above example, if the first fastening portion 11 is a bolt, the fitting hole 403 should be provided with an internal thread, so that the external thread of the bolt is screwed with the internal thread of the fitting hole 403, and when the head of the bolt abuts against the end surface of the mounting hole 104, the first rotating shaft 1 is connected with the supporting member 4. Wherein, the mounting hole 104 and the fitting hole 403 may be horizontally disposed so that the first fastening portion 11 horizontally fastens the first rotating shaft 1 and the support member 4, and furthermore, the end surface of the mounting hole 104 may be disposed as a plane, thereby facilitating the head portion of the bolt and the plane to be closely fitted.
The connection mode of the second rotating shaft 7 and the support 4 is the same as that of the first rotating shaft 1 and the support 4, and will not be described in detail herein.
Meanwhile, the first fastening part 11 and the second fastening part 8 located in the inner cavity 103 reduce the possibility of contact with external parts, and prevent the first fastening part 11 and the second fastening part 8 from loosening due to touch of the external parts, thereby further improving the connection reliability of the first rotating shaft 1 and the second rotating shaft 7 compared with the support 4.
Regarding the structure of the inner cavity 103, as shown in fig. 2 to 4, the inner cavity 103 may be provided with a tapered structure, and the cross-sectional dimension of the inner cavity 103 gradually decreases from the opening of the inner cavity 103 to the direction close to the mounting hole 104.
Taking the orientation shown in fig. 4 of the specification as an example, the opening of the inner cavity 103 faces to the left, the supporting member 4 and the mounting hole 104 are located on the right, and the transverse section of the inner cavity 103 gradually becomes smaller in the left-to-right direction; obviously, the advantage of such an arrangement is that when the first fastening part 11 needs to be installed, the inner cavity 103 has enough space for installation operation, so that the convenience of assembly is improved, and the improvement of assembly efficiency is ensured.
Referring to the description of fig. 6 and 7, the first rotating shaft 1 and the second rotating shaft 7 are both provided with a first tooth portion 102 near the end surface of the support 4, and both sides of the support 4 are provided with second tooth portions 402 which cooperate with the first tooth portion 102 to transmit torque.
In short, the first rotating shaft 1 and the support member 4, and the second rotating shaft 7 and the support member 4 are attached through the first tooth portion 102 and the second tooth portion 402, so that when the first rotating shaft 1 and the second rotating shaft 7 rotate to drive the support member 4 to perform pitch adjustment, torque can be transmitted between the first tooth portion 102 and the second tooth portion 402, rather than only by relying on the first fastening portion 11 and the second fastening portion 8 to transmit torque, thereby helping to reduce the torque borne by the first fastening portion 11 and the second fastening portion 8 and improving the stability of pitch adjustment.
Meanwhile, in the assembling process, when the relative positions of the first rotating shaft 1 and the support member 4 need to be determined, the first rotating shaft 1 can be automatically centered through the matching of the first tooth portion 102 and the second tooth portion 402, that is, the position relation of the first rotating shaft 1 relative to the support member 4 is automatically adjusted under the matching action of the first tooth portion 102 and the second tooth portion 402, so that the position adjusting process between the first rotating shaft 1 and the support member 4 is greatly simplified, the assembling efficiency is improved, and the assembling precision is improved.
Referring to fig. 7 of the specification, both sides of the support 4 have connection flanges 401 extending toward the outside, and second teeth 402 are provided to the connection flanges 401. By arranging the second tooth portion 402 on the connecting flange 401, the processing and forming of the second tooth portion 402 are facilitated, the mechanical processing or the injection molding is facilitated, and the structural reliability of the support 4 is improved, so that the connection reliability of the support 4 is ensured compared with the connection reliability of the first rotating shaft 1 and the second rotating shaft 7.
The first tooth portion 102 and the second tooth portion 402 can be arranged in a ring shape, as shown in fig. 6 and fig. 7 in the specification, the ring-shaped first tooth portion 102 and the ring-shaped second tooth portion 402 can bear the torque to the maximum, and each tooth on the first tooth portion 102 and the second tooth portion 402 can share the torque to a certain extent, so that the reliability of the pitch angle adjustment is improved.
As shown in fig. 2 and fig. 3, the rotating shaft assembly further includes a first bearing 2 and a second bearing 6, and the first rotating shaft 1 and the second rotating shaft 7 are provided with a shoulder 101 for respectively abutting against the first bearing 2 and the second bearing 6 in the axial direction.
Obviously, in order to realize the rotation of the first rotating shaft 1 and the second rotating shaft 7 around the fixed shaft, the first rotating shaft 1 may be sleeved with the first bearing 2, the second rotating shaft 7 may be sleeved with the second bearing 6, and the outer rings of the first bearing 2 and the second bearing 6 should be fixed during the assembling process.
Taking the attached fig. 3 and fig. 4 of the specification as an example, the cavity inner groove 12 is used as a fixed position component, which can be used to fix the outer rings of the first bearing 2 and the second bearing 6, when the outer rings of the first bearing 2 and the second bearing 6 are fixed relative to the cavity inner groove 12, the first rotating shaft 1 can be sleeved on the inner ring of the first bearing 2, and the second rotating shaft 7 can be sleeved on the inner ring of the second bearing 6.
Because the first rotating shaft 1 and the second rotating shaft 7 are provided with the shaft shoulders 101 for respectively abutting against the first bearing 2 and the second bearing 6, the axial limiting can be realized. In this way, the first rotating shaft 1 can be rotated by the radial direction stopper action of the first bearing 2, and the second rotating shaft 7 can be rotated by the radial direction stopper action of the second bearing 6.
In order to avoid the leakage phenomenon at the positions of the first bearing 2 and the second bearing 6, the first rotating shaft 1 is further sleeved with a first oil seal ring 3, and the first oil seal ring 3 is positioned at one end of the first bearing 2 close to the supporting piece 4; the second rotating shaft 7 is further sleeved with a second oil seal ring 5, and the second oil seal ring 5 is located at one end of the second bearing 6 close to the supporting member 4, as shown in fig. 2 to 4 of the specification.
Continuing with the above example, the cavity inner groove 12 serves as a fixed part, which can be used not only for fixing the outer rings of the first bearing 2 and the second bearing 6, but also for fixing the first oil seal ring 3 and the second oil seal ring 5.
In the assembling process, firstly, the position fixing of the first bearing 2, the second bearing 6, the first oil seal ring 3 and the second oil seal ring 5 is completed, then the first rotating shaft 1 and the second rotating shaft 7 are respectively installed, so that the shaft shoulder 101 of the first rotating shaft 1 is abutted against the first bearing 2, the shaft shoulder 101 of the second rotating shaft 7 is abutted against the second bearing 6, and finally, the connection with the supporting piece 4 is respectively realized through the first fastening part 11 and the second fastening part 8.
Of course, the fixing manner of the first bearing 2, the second bearing 6, the first oil seal ring 3 and the second oil seal ring 5 is not limited to the fixing by the cavity inner groove 12, and may be fixed to other components according to actual needs, which is not limited herein.
Obviously, it can be seen that the sealing between the first rotating shaft 1 and the first bearing 2 can be ensured by the sealing function of the first oil seal ring 3, and the sealing between the second rotating shaft 7 and the second bearing 6 can be ensured by the second oil seal ring 5, so that the normal rotation of the first rotating shaft 1 and the second rotating shaft 7 is realized, and the adjustment of the pitch angle of the supporting member 4 is ensured.
With respect to the specific position design of the first bearing 2 and the second bearing 6, referring to the attached drawing 5 in the specification, the first rotating shaft 1 and the second rotating shaft 7 are symmetrically arranged on both sides of the support 4, and the shape and the size of the first rotating shaft 1 are the same as those of the second rotating shaft 7, it is obvious that the first bearing 2 and the second bearing 6 are also symmetrically arranged on both sides of the support 4, and the shape and the size of the first bearing 2 are the same as those of the second bearing 6.
First, a distance between a fixing surface between the first rotating shaft 1 and the support 4 and the shoulder 101 of the first rotating shaft 1 is defined as L1, a width of the support 4 is defined as L2, and a distance between the first bearing 2 and the second bearing 6 is defined as L. It is obvious that the distance between the fixing surface between the second rotating shaft 7 and the support 4 and the shoulder 101 of the second rotating shaft 7 should also be L1.
At design time, 2 × L1+ L2 ═ L + Δl is required. Wherein Δ L > 0.
After the first rotating shaft 1 and the supporting piece 4 are locked and fixed and the second rotating shaft 7 and the supporting piece 4 are locked and fixed, the play of the first bearing 2 and the second bearing 6 can be eliminated, so that the axial pre-tightening of the first rotating shaft 1 and the second rotating shaft 7 is realized, and the axial movement of the first rotating shaft 1 and the second rotating shaft 7 is eliminated.
Generally, Δ L is 0.2mm to 0.3 mm. The overlarge value of delta L can cause the axial pre-tightening of the first bearing 2 and the second bearing 6 to be too large, so that the friction force is increased; the axial pre-tightening of the first bearing 2 and the second bearing 6 is insufficient due to the excessively small value of Delta L, and the play of the first bearing 2 and the second bearing 6 cannot be eliminated, so that the first rotating shaft 1 and the second rotating shaft 7 are axially moved in a string manner.
In consideration of the waterproof performance of the rotating shaft assembly, a first sealing ring 10 is arranged between the first rotating shaft 1 and the support 4, and a second sealing ring 9 is arranged between the second rotating shaft 7 and the support 4, as shown in the accompanying drawings 2-4 in the specification. Obviously, the waterproof performance of the joint between the first rotating shaft 1 and the support 4 can be realized through the first sealing ring 10, and the waterproof performance of the joint between the second rotating shaft 7 and the support 4 can be ensured through the second sealing ring 9. On the premise that the shapes and the sizes of the first rotating shaft 1 and the second rotating shaft 7 are the same, the shapes and the sizes of the first sealing ring 10 and the second sealing ring 9 can also be the same, so that the interchangeability is improved, and the assembly process is simplified.
Considering pivot subassembly application in fields such as cloud platform, can set up first pivot 1, support piece 4 and second pivot 7 into hollow structure, also be the axial both ends intercommunication of first pivot 1 and second pivot 7, support piece 4's inside respectively with first pivot 1 and second pivot 7 intercommunication for parts such as confession cables wear to establish in hollow structure, prior art can be referred to its specific setting mode, and it is no longer repeated here.
