Description

Technical Field

[0001] The utility model relates to the technical field of hollow shaft motors, in particular to a signal magnetic ring component. Background Art

[0002] The hollow shaft brake motor determines the rotor position by sensing the signal magnetic ring through the chip, which requires the signal magnetic ring to have very good structure and assembly reliability and cost-effectiveness.

[0003] However, the existing signal magnetic ring is made by separately processing the magnetic ring and the hollow shaft and then bonding them together, or by stretching the thin-walled metal parts and then injection-molding the signal magnetic ring as one. The signal magnetic ring that is bonded may fall off under high temperature and high speed. The dimensional consistency of the thin-walled metal parts and the difficulty in mold realization make it difficult to ensure the subsequent overall stability. In addition, the thin-walled metal parts may be greatly deformed on the production line during the subsequent interference fit process, resulting in poor assembly quality. Utility Model Content

[0004] The purpose of the utility model is to provide a signal magnetic ring assembly to solve the problems of easy falling off, poor stability and large deformation of the signal magnetic ring proposed in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a signal magnetic ring assembly, comprising:

[0006] A steel sleeve assembly, wherein the upper outer wall of the steel sleeve assembly is provided with a signal magnetic ring, and the interior of the signal magnetic ring penetrates a limit piece;

[0007] A steel sleeve assembly, comprising a steel sleeve assembly, a threaded member disposed above the steel sleeve assembly, and a docking member disposed below the steel sleeve assembly;

[0008] A stabilizing component includes a limiter, an outer wall of the signal magnetic ring is connected to a rubber ring, a surface of the rubber ring is provided with a No. 1 hole, an outer wall of the rubber ring is connected to a rotating ring, a surface of the rotating ring is provided with a No. 2 hole.

[0009] Preferably, the size of the docking piece is consistent with the size of the main shaft of the hollow shaft.

[0010] Preferably, the steel sleeve assembly is formed by cutting a cylindrical grinding tube having a certain thickness.

[0011] Preferably, the signal magnetic ring is injection molded onto the upper end of the steel sleeve assembly through an injection mold.

[0012] Preferably, the signal magnetic ring component is threadedly connected to the threaded component, and the rubber ring is fixedly connected to the rotating ring.

[0013] Preferably, the signal magnetic ring component is provided with a hole corresponding to the limiting component, and the steel sleeve component is provided with a groove corresponding to the limiting component.

[0014] Preferably, the positions of the No. 1 hole and the No. 2 hole are the same, and the rubber ring is rotatably connected to the signal magnetic ring.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] (1) The new signal magnetic ring assembly is provided with a steel sleeve assembly and a signal magnetic ring component. Compared with the prior art, this structure can avoid the situation where the induction magnetic ring falls off during operation due to bonding failure of the signal magnetic ring component, thereby improving the reliability of the product; the steel sleeve assembly of this structure is easy to process, does not require mold forming, and has low production cost; the structure has a thick wall, and interference press fitting will not cause plastic deformation on the production line, and has good production processability.

[0017] (2) The new signal magnetic ring assembly is equipped with a stabilizing assembly, and the limit piece is inserted into the groove of the steel kit through the hole of the signal magnetic ring. The swivel is then rotated, and the swivel rotates together with the rubber ring, so that the No. 1 hole and the swivel are away from the limit piece, and the rubber ring and the swivel are against the limit piece, which further ensures the stability of the position of the signal magnetic ring and improves the reliability of the product.

[0028] Stabilizing component 03, stabilizing component 03 includes a limiter 31, which is inserted into the groove of the steel kit 11 through the hole of the signal magnetic ring 02 to fix the position of the signal magnetic ring 02. The outer wall of the signal magnetic ring 02 is connected to a rubber ring 32, which acts as a damping device to ensure that the rubber ring 32 does not rotate during use of the overall structure. A hole No. 1 is provided on the surface of the rubber ring 32, and a swivel 34 is connected to the outer wall of the rubber ring 32. A hole No. 2 35 is provided on the surface of the swivel 34. The hole No. 1 33 and the hole No. 2 35 are rotated to the position of the limiter 31, and the limiter 31 can be pulled out of the hole of the signal magnetic ring 02.

[0029] Furthermore, the size of the docking member 13 is consistent with the size of the main shaft of the hollow shaft, which facilitates docking of the structure with the main shaft of the hollow shaft.

[0030] Furthermore, the steel sleeve component 01 is processed by cutting a cylindrical grinding tube with a certain thickness, which ensures the structural wall thickness, and the interference fit will not cause plastic deformation of the production line, and the production processability is good.

[0031] Furthermore, the signal magnetic ring 02 is injection molded onto the upper end of the steel sleeve assembly 01 to ensure that the texture of the inner wall of the signal magnetic ring 02 matches the threaded part 12, and the signal magnetic ring 02 can be screwed onto the outer wall of the threaded part 12.

[0032] Furthermore, the signal magnetic ring 02 is threadedly connected to the threaded member 12, and the rubber ring 32 is fixedly connected to the rotating ring 34. The rubber ring 32 plays a damping role to ensure that the rubber ring 32 does not rotate during use of the entire structure.
