Description

Technical Field

[0001] This utility model belongs to the field of nut technology, specifically relating to a spindle nut. Background Technology

[0002] Nuts are fasteners that are screwed onto bolts or screws for securing purposes. They are essential components in all manufacturing machinery and can be categorized into several types based on their material, including carbon steel, stainless steel, and non-ferrous metals. Spindle nuts, on the other hand, are locking components used on and mating with spindles, and are primarily available in hexagonal and cylindrical shapes.

[0003] The existing spindle nuts have poor locking effect and are prone to loosening during use under the influence of factors such as vibration, which reduces their safety. Utility Model Content

[0004] Based on the problems mentioned in the background art above, this utility model provides a spindle nut to solve the problem that existing spindle nuts have poor locking effect and are prone to loosening during use under the influence of factors such as vibration.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A spindle nut, comprising:

[0007] Nut body;

[0008] The extrusion members are provided in multiples and are arranged in a radial array on the periphery of the nut body by means of an installation structure;

[0009] The filling structure is provided in multiple ways, and each filling structure is disposed in a corresponding extrusion member.

[0010] Based on the above technical solution, the present invention has made the following improvements:

[0011] Furthermore, the nut body has multiple slots arranged in an array on its peripheral sidewall.

[0012] Furthermore, the mounting structure includes a screw hole and a receiving groove. The screw hole is radially disposed at the bottom of the slot, and the receiving groove is disposed at the end of the screw hole facing the center of the nut body.

[0013] Furthermore, the extrusion component includes an adjusting stud, an assembly plate, and a natural rubber block. The adjusting stud is threaded into a screw hole. The assembly plate is located in a receiving groove and is rotatably sleeved on the smooth part of the adjusting stud. One side of the assembly plate is in contact with the annular flange on the adjusting stud, and the other side is in contact with the retaining ring sleeved on the end of the smooth part of the adjusting stud. The natural rubber block is vulcanized and bonded to the side of the assembly plate near the center of the nut body.

[0014] Furthermore, the filling structure includes a storage cavity disposed within a natural rubber block, and an extrusion hole is provided through the storage cavity on the side near the center of the nut body.

[0015] The beneficial effects of this utility model are:

[0016] 1. By using the installation structure and the combination of extrusion components, the extrusion components are arranged radially in an array on the periphery of the nut body through the installation structure. This allows the extrusion components to be tightly pressed against the external thread on the spindle after the spindle nut is installed on the spindle, thereby locking and reinforcing the nut body.

[0017] 2. Through the set filling structure, the filling structure is filled with locking agent. During the process of the extrusion member being tightly pressed onto the external thread on the main shaft, the locking agent is squeezed out from the filling structure and filled at the joint between the extrusion member and the external thread on the main shaft. After the locking agent is cured, it can further stabilize the nut body. Attached Figure Description

[0024] like Figures 1-3 As shown, a spindle nut includes:

[0025] Nut body 101, with multiple slots 102 arranged in an array on the peripheral sidewall of nut body 101. Each slot 102 can be used with a crescent wrench. That is, by inserting the end of the crescent wrench into the corresponding slot 102, the nut body 101 can be rotated, so that the nut body 101 can be assembled onto the threaded part of the spindle.

[0026] The extrusion components are provided in multiples and are arranged radially in an array within the periphery of the nut body 101 via an installation structure. The installation structure includes a screw hole 103 and a receiving groove 104. The screw hole 103 is arranged radially at the bottom of the slot 102, and the receiving groove 104 is arranged at the end of the screw hole 103 facing the center of the nut body 101. The screw hole 103 and the receiving groove 104 are in communication.

[0027] The extrusion component includes an adjusting stud 201, an assembly plate 202, and a natural rubber block 205. The adjusting stud 201 is threaded into the screw hole 103. The assembly plate 202 is located in the receiving groove 104 and is rotatably sleeved on the smooth part of the adjusting stud 201. One side of the assembly plate 202 is in contact with the annular flange 203 on the adjusting stud 201, and the other side is in contact with the retaining ring 204 sleeved on the end of the smooth part of the adjusting stud 201, so that the adjusting stud 201 and the assembly plate 202 are assembled together. The natural rubber block 205 is vulcanized and bonded to the side of the assembly plate 202 near the center of the nut body 101, so that the natural rubber block 205 and the assembly plate 202 are assembled into one piece.

[0028] During the process of screwing the nut body 101 into the main shaft thread, the natural rubber block 205 is housed in the receiving groove 104. After the nut body 101 is screwed into the main shaft thread, the adjusting stud 201 is rotated to move it closer to the center of the nut body 101, thereby driving the assembly plate 202 and the natural rubber block 205 to move closer to the center of the nut body 101. This causes the natural rubber block 205 to continuously press the external thread of the main shaft towards the side of the nut body 101, so that the pressing surface of the natural rubber block 205 deforms and tightly presses against the external thread of the main shaft, thereby locking and reinforcing the nut body 101.

[0029] The filling structure includes multiple filling structures, each set within a corresponding extrusion member. Each filling structure includes a storage cavity 301, which is located within a natural rubber block 205. An extrusion hole 302 is provided through the storage cavity 301 on the side closest to the center of the nut body 101. Locking agent can be pre-filled into the storage cavity 301 through the extrusion hole 302, so that the locking agent is pre-filled in the storage cavity 301. The locking agent can be Loctite 243 or Loctite 263.

[0030] After the nut body 101 is assembled onto the spindle thread, and the extrusion surface of the natural rubber block 205 is deformed and tightly pressed against the external thread of the spindle, the locking agent in the storage cavity 301 can be squeezed out through the extrusion hole 302, so that the locking agent fills the joint between the extrusion surface of the natural rubber block 205 and the external thread of the spindle. After the locking agent cures, the extrusion surface of the natural rubber block 205 can be bonded to the external thread of the spindle, further stabilizing the nut body 101.

[0031] The present invention has been described in detail above. The specific embodiments are provided only to help understand the method and core idea of ​​the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
