Description

Technical Field

[0001] The utility model belongs to the technical field of motor accessories, in particular to a lantern-shaped soft-connection type vibration component. Background Art

[0002] According to their power direction, motors can be divided into two types: rotating motors and vibration motors. Among them, the vibration motor mainly includes an outer casing, rotor windings and stator windings, as well as auxiliary accessories that connect its various components to each other. The accessories are represented by soft connectors, which are a type of coupling. The soft connector connects the rotor shaft of the vibration motor with the main shaft of the exciter, thereby forming a complete whole, which is the entire vibration assembly.

[0003] A Chinese patent application (or patent) with the announcement number CN204391969U discloses a vibration-resistant vibration motor, including a housing and a stator winding and a rotor winding arranged in the housing, characterized in that: the housing is fixed on the motor support seat, the two ends of the rotor shaft are respectively connected to the exciter main shaft through a flexible coupling, and the ends of the exciter main shaft are respectively fixed with eccentric mass blocks, which are supported on the exciter housing through bearings and bearing seats, and the exciter housing is fixed on the exciter support. The utility model makes the equipment run more smoothly, reduces the centrifugal force acting on the motor rotor shaft, and plays a fundamental role in extending the service life of the motor. Again, the center of gravity of the vibration device separated at both ends is at the reinforced position of the equipment, which reduces the destructive force on the equipment, and the vibration source directly acts on the transmission part of the equipment, so that the screening of the equipment is faster and cleaner, greatly reducing the cost of use, and more convenient maintenance.

[0004] The above-mentioned vibration-resistant vibration motor has two connection plates at both ends of the soft connection coupling, and the two connection plates are movably connected to the soft connection coupling. At the same time, a belt-shaped deceleration device is additionally provided between the two connection plates, thereby achieving the effect of buffering the mutual collision between the two connection plates. However, because the connection plate is a vulnerable part, it not only needs to be inspected and maintained, but also needs to meet the performance of easy disassembly and assembly. When assembling, the connection plate is placed in the soft connection connector by bolts and baffles. When the entire soft connection coupling is working, it will also be subjected to certain vibration and impact, and the bolts are placed in the vibration In the axial direction of movement and collision, the bolts may loosen or even fall off, which may cause the connection disk to detach from the main body of the flexible connection coupling; and, a connection disk is provided at both ends of the main body of the flexible connection coupling, and the connection disk is movably connected to the main body of the flexible connection coupling. When the connection disk is installed with the main shaft and the rotor shaft, when it is working, the shaft will carry the connection disk to make a piston movement of a certain distance in the main body of the flexible connection coupling, and the piston movement will also cause a collision between the connection disk and the main body of the flexible connection coupling. This collision will not only bring huge noise, but also cause certain damage to the flexible connection coupling. To this end, we provide a lantern-shaped soft-connection vibration assembly to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0029] See also Figure 1-3 The utility model is a lantern-shaped soft-connection vibration component, including a shell 1 and an elastic structure 6 installed inside the shell 1.

The rotor shaft 4 and the exciter main shaft 5 on both sides of the shell 1 can be softly connected with the tower-shaped spring sheets 602, and the other end of the tower-shaped spring sheet 602 is connected to the assembly column 603. At the same time, the other end of the assembly column 603 contacts the inner wall of the shell 1 through the elastic sheet 604 and the rubber ring 605, thereby avoiding the occurrence of collision.

[0030] Specifically, the tower-shaped springs 602 on both sides of the center disk 601 in the elastic structure 6 are bonded to it, and the other end of the tower-shaped spring 602 is bonded to the assembly column 603, and the cross-section of the assembly column 603 is in a "T" shape, with one end of its small axial surface facing the outside of the shell 1, and one end of the small axial surface is threadedly connected to one end of the connecting tube 301, and the other end of the connecting tube 301 is threadedly connected to the rotor shaft 4 or the exciter main shaft 5.

Specific embodiment 2

[0033] See also Figure 4-5 On the basis of the specific embodiment 1, a connecting structure 3 is further provided, and the connecting structure 3 is installed at both ends of the shell 1, wherein the connecting structure 3 includes a connecting tube 301 stuck in the axle box 103, and buffer pads 302 are additionally provided on both sides of the connecting tube 301, and elastic rods 303 are also inserted in the buffer pads 302. At the same time, the axial end of the elastic rod 303 is threadedly connected to the circular hole 103d on the axle box 103, so that the connecting tube 301 is convenient to be assembled into the axle box 103 of the shell 1, and it is also convenient to be removed, and the buffer pad 302 and buffer spring 302b therein can play an effective buffering and anti-collision effect, and the elastic rod 303 and the abutment block 304 at its axial end can prevent the connecting tube 301 from being separated from the axle box 103.

[0034] Specifically, an axle box 103 is installed on each of the two axial ends of the housing 1, and a box groove 103a is provided in the axle box 103 for accommodating the connecting tube 301 in the connecting structure 3, and a slot 103b for allowing the angle plate 301a to pass through is provided on the outer end side wall of the box groove 103a, and a bottom groove 103c for cooperating with the abutment block 304 is provided on the rear inner wall of the box groove 103a corresponding to the slot 103b, and a round hole 103d for threaded connection with the elastic rod 303 is also provided in the bottom groove 103c.

The block 304 is then released from the contact force of the angle plate 301a, and the elastic rod 303 on its rear side returns to its initial state, and moves toward the slot 103b again with the block 304, and is inserted into the slot 103b, completing the sealing operation of the slot 103b. The assembly and disassembly are simple and easy to operate, and the assembly position can be automatically sealed after assembly to avoid mutual separation during operation. When the block 304 is working, the buffer pad 302 in the box slot 103a cooperates with the buffer spring 302b to avoid distance collision between the angle plate 301a and the inner walls at both ends of the box slot 103a.
