Description

Technical Field

[0001] The utility model relates to the technical field of locking components, in particular to a locking component used on a rotating shaft. Background Art

[0002] The rotating shaft is generally assembled on various mechanical equipment through bearings and driven by a motor to rotate. The rotating shaft and the bearing need to be fixed with a locking assembly. The locking assembly is generally fixed and locked through the friction between the bearing and the rotating shaft with the aid of rubber.

[0003] In actual work, the structure and function of the locking assembly in the prior art are relatively perfect and can basically meet the daily use needs, but there are still the following problems:

[0004] During actual use, the bearing and the shaft are fixed by friction and rubber components, and bearings and shafts of different thicknesses cannot be fit and locked, which results in a gap between the bearing and the shaft, making it easy for sliding to occur, and the bearing and the shaft are also prone to rotation, which makes it easy for the shaft and the bearing to separate.

[0005] Therefore, the utility model provides a locking assembly for a rotating shaft. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings of the prior art and provide a locking assembly for a rotating shaft.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a locking assembly for a rotating shaft, comprising a rotating shaft body,

[0008] The outer surface of the rotating shaft body is sleeved with a bearing, and an auxiliary locking structure is provided between the rotating shaft body and the bearing;

[0009] An auxiliary fixing structure is provided on one side of the auxiliary locking structure;

[0010] The auxiliary locking structure includes a fixed ring block, the inner wall of which is fixedly connected to the outer surface of the rotating shaft body, a circular groove is provided on one side of the outer surface of the fixed ring block, a rubber round block is fixedly connected to the inner wall of the circular groove, and an external thread is provided on the outer surface of the rotating shaft body.

[0011] As a preferred embodiment, the outer surface of the external thread is threadedly connected to a threaded barrel, one side of the outer surface of the threaded barrel is fixedly connected to a resistance ring block, the inner wall of the resistance ring block is threadedly connected to a threaded extrusion rod, one end of the outer surface of the threaded extrusion rod is fixedly connected to a rubber extrusion block, one side of the outer surface of the threaded barrel is fixedly connected to a fixed ring frame, and the inner wall of the fixed ring frame is threadedly connected to a threaded fixing rod.

[0012] The technical effect of adopting the above further solution is that: under the action of the fixed ring block, it can cooperate with the rubber round block to limit one side surface of the inner ring of the bearing. Under the combined action of the external thread and the threaded cylinder, the abutting ring block can limit the bearing. Furthermore, under the action of the threaded extrusion rod, it can cooperate with the rubber extrusion block to assist in fixing the inner ring of the bearing, and can avoid the rotation of the inner ring of the bearing while assisting in limiting the bearing.

[0013] As a preferred embodiment, the auxiliary fixing structure includes a circular clamping frame. One side of the outer surface of the circular clamping frame is fixedly connected to one side of the outer surface of the fixed ring frame. The inner wall of the circular clamping frame is clamped with a circular clamping block. One side of the outer surface of the circular clamping block is fixedly connected to a connecting rod. One end of the connecting rod is fixedly connected to an auxiliary clamping plate. Two sides of the inner wall of the circular clamping frame are symmetrically provided with first insertion holes. The inner wall of the circular clamping block is provided with a second insertion hole. The inner walls of the first insertion hole and the second insertion hole are inserted with threaded insertion rods. One end of the outer surface of the threaded insertion rod is threadedly connected to a fixing nut.

[0014] The technical effect of adopting the above further solution is that: under the action of the circular clamping block and the circular clamping frame, the auxiliary clamping plate can assist in fixing the rotating shaft, thereby avoiding the rotation between the threaded cylinder and the external thread, and further avoiding the separation between the threaded cylinder and the rotating shaft.

[0015] As a preferred embodiment, the inner wall of the auxiliary clamping plate is threadedly connected with a threaded rod. The bottom end of the outer surface of the threaded rod is rotatably connected to a rubber clamping plate. The top of the outer surface of the rubber clamping plate is symmetrically and fixedly connected with limiting round rods. The limiting round rods are slidably arranged on the inner wall of the auxiliary clamping plate.

[0016] The technical effect of adopting the above further solution is that: under the action of the threaded rod, under the action of the rubber clamping plate, the friction between the threaded cylinder and the rotating shaft can be increased, thereby effectively avoiding the rotation of the threaded cylinder and the rotating shaft, and further avoiding the situation of separation between the threaded cylinder and the rotating shaft.

[0017] Compared with the prior art, the advantages and positive effects of the present utility model are that

[0018] By setting a fixed ring block and a rubber round block, the rotating shaft body and the bearing can be auxiliary fixed in cooperation with the resistance ring block and the threaded extrusion rod and the rubber extrusion block on the resistance ring block, thereby avoiding rotation between the bearing and the rotating shaft body. At the same time, under the action of the fixed ring frame and the threaded fixing rod, the threaded tube and the rotating shaft body can be squeezed and fixed, thereby avoiding rotation and separation. Under the action of the circular clamping frame and the circular clamping block, the auxiliary splint can be fixed, thereby increasing the friction between the rotating shaft body and the threaded tube. At the same time, under the action of the threaded rod and the rubber splint, the friction is further increased, thereby preventing the threaded tube and the rotating shaft body from rotating and separating easily.

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] As Figures 1-4 shown, this embodiment provides a technical solution: a locking assembly for a rotating shaft, including a rotating shaft body 1, a bearing 2 is sleeved on the outer surface of the rotating shaft body 1, and an auxiliary locking structure 3 is arranged between the rotating shaft body 1 and the bearing 2; an auxiliary fixing structure 4 is arranged on one side of the auxiliary locking structure 3; the auxiliary locking structure 3 includes a fixed ring block 31, the inner wall of the fixed ring block 31 is fixedly connected to the outer surface of the rotating shaft body 1, a circular groove 32 is opened on one side of the outer surface of the fixed ring block 31, a rubber circular block 33 is fixedly connected to the inner wall of the circular groove 32, and an external thread 34 is opened on the outer surface of the rotating shaft body 1.

[0029] By setting the fixed ring block 31 and the rubber circular block 33, the contact ring block 36 and the threaded extrusion rod 37 and the rubber extrusion block 38 on the contact ring block 36 can be used to assist in fixing the rotating shaft body 1 and the bearing 2, so as to avoid rotation between the bearing 2 and the rotating shaft body 1. At the same time, under the action of the fixed ring frame 39 and the threaded fixing rod 310, the threaded cylinder 35 and the rotating shaft body 1 can be extruded and fixed, so as to avoid rotation and resulting in separation. Under the action of the circular clamping frame 41 and the circular clamping block 43, the auxiliary clamping plate 48 can be fixed, so that the friction force between the rotating shaft body 1 and the threaded cylinder 35 becomes larger. At the same time, under the action of the threaded rod 49 and the rubber clamping plate 410, the friction force is further increased, so that the threaded cylinder 35 and the rotating shaft body 1 will not easily rotate and separate.

[0030] Further, as Figure 2 and Figure 3As shown in the figure: The outer surface of the external thread 34 is threadedly connected with a threaded cylinder 35. One side of the outer surface of the threaded cylinder 35 is fixedly connected with a contact ring block 36. The inner wall of the contact ring block 36 is threadedly connected with a threaded extrusion rod 37. One end of the outer surface of the threaded extrusion rod 37 is fixedly connected with a rubber extrusion block 38. One side of the outer surface of the threaded cylinder 35 is fixedly connected with a fixed ring frame 39. The inner wall of the fixed ring frame 39 is threadedly connected with a threaded fixing rod 310. Under the action of the fixed ring block 31, it can cooperate with the rubber round block 33 to limit one side surface of the inner ring of the bearing 2. Under the combined action of the external thread 34 and the threaded cylinder 35, the contact ring block 36 can limit the bearing 2. Furthermore, under the action of the threaded extrusion rod 37, it can cooperate with the rubber extrusion block 38 to assist in fixing the inner ring of the bearing 2, and can avoid the inner ring of the bearing 2 from rotating while assisting in limiting the bearing 2.

[0031] In the above solution, there is also a problem that the threaded cylinder 35 is prone to rotation, which may lead to separation from the rotating shaft body 1, as shown in Figure 3 and Figure 4 As shown in the figure: In this solution, the auxiliary fixing structure 4 includes a circular clamping frame 41. One side of the outer surface of the circular clamping frame 41 is fixedly connected with one side of the outer surface of the fixed ring frame 39. The inner wall of the circular clamping frame 41 is clamped with a circular clamping block 43. One side of the outer surface of the circular clamping block 43 is fixedly connected with a connecting rod 47. One end of the connecting rod 47 is fixedly connected with an auxiliary clamping plate 48. Two symmetric first insertion holes 42 are opened on both sides of the inner wall of the circular clamping frame 41. A second insertion hole 44 is opened on the inner wall of the circular clamping block 43. A threaded insertion rod 45 is inserted into the inner walls of the first insertion hole 42 and the second insertion hole 44. One end of the outer surface of the threaded insertion rod 45 is threadedly connected with a fixing nut 46. Under the action of the circular clamping block 43 and the circular clamping frame 41, the auxiliary clamping plate 48 can assist in fixing the rotating shaft body 1, thereby avoiding rotation between the threaded cylinder 35 and the external thread 34, and further avoiding separation between the threaded cylinder 35 and the rotating shaft body 1.

[0032] In the above solution, there is also a problem that the auxiliary clamping plate 48 does not fit tightly with the rotating shaft body 1, which may lead to a weakened fixing effect of the auxiliary clamping plate 48, as shown in Figure 4 As shown in the figure, the inner wall of the auxiliary clamping plate 48 is threadedly connected with a threaded rod 49. The bottom end of the outer surface of the threaded rod 49 is rotatably connected with a rubber clamping plate 410. Two symmetric limiting round rods 411 are fixedly connected to the top of the outer surface of the rubber clamping plate 410. The limiting round rods 411 are slidably arranged on the inner wall of the auxiliary clamping plate 48. Under the action of the threaded rod 49, it can increase the friction force between the threaded cylinder 35 and the rotating shaft body 1 under the action of the rubber clamping plate 410, thereby effectively avoiding rotation between the threaded cylinder 35 and the rotating shaft body 1, and further avoiding the situation of separation between the threaded cylinder 35 and the rotating shaft body 1.

[0033] Working principle:

[0034] As Figures 1-4 shown:

[0035] When in use: The bearing 2 is sleeved on the outer surface of the rotating shaft body 1, so that the bearing 2 is squeezed and fixed with the rubber round block 33 on the fixed ring block 31. At this time, the threaded cylinder 35 is squeezed and fixed with the external thread 34, and then the abutting ring block 36 can be fixed with the bearing 2;

[0036] At this time, rotate the threaded extrusion rod 37 so that the threaded extrusion rod 37 can drive the rubber extrusion block 38 to move, and then the bearing 2 can be assisted in clamping. At this time, rotate the threaded fixing rod 310 so that the threaded fixing rod 310 is squeezed and fixed with the rotating shaft body 1;

[0037] At this time, the circular clamping block 43 is inserted into the inner wall of the circular clamping frame 41. At this time, the threaded insertion rod 45 is inserted into the inner walls of the first insertion hole 42 and the second insertion hole 44, and then the fixing nut 46 is fixed with the threaded insertion rod 45;

[0038] At this time, rotate the threaded rod 49 so that the threaded rod 49 can drive the rubber clamping plate 410 to move, and then the rubber clamping plate 410 can be assisted in fixing with the rotating shaft body 1.

[0039] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
