Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

As shown in fig. 1 to 5, the present invention discloses an integrated vibration motor, which comprises a housing 10, a rotating shaft 30, a stator 61, a rotor 62, two end caps 20, two sealing members 50, two eccentric blocks 70 and two bearings 40.

The housing 10 is made of stainless steel, and a terminal box 11, preferably an explosion-proof terminal box 11, is provided outside the housing 10 for connecting to a power supply. In addition, a plurality of heat dissipation fins are further disposed on the outer wall of the casing 10 to enhance the heat dissipation effect of the vibration motor. An oil chamber 12 is formed inside the housing 10, and an inlet and an outlet are formed at both ends of the oil chamber 12. The two end covers 20 are respectively connected with the inlet and the outlet of the two ends of the oil chamber 12 in a sealing way and are locked by screws.

The rotating shaft 30 is rotatably connected in the oil chamber 12 through a bearing 40, the two end heads of the rotating shaft 30 penetrate through the end cover 20 and extend out of the oil chamber 12, and the sealing element 50 seals a gap between the rotating shaft 30 and the end cover 20. The sealing member 50 is preferably a mechanical seal, which ensures that the gap between the rotating shaft 30 and the end cover 20 is effectively sealed, and has a long service life. The oil chamber 12 is sealed by the cooperation of the shaft 30, the seal 50, the end cap 20 and the housing 10. Insulating lubricating oil, preferably transformer oil, is filled in the oil cavity 12, and has the advantages of good insulation, good heat dissipation, arc extinction and the like.

The two end heads of the rotating shaft 30 extend out of the oil chamber 12 and are fixedly connected with an eccentric block 70 respectively. A shield 13 for covering the eccentric mass 70 is further provided at each of both end sides of the housing 10, and the shield 13 is detachably and hermetically coupled to the housing 10 by screws. The shield 13 may function as a dust-proof and water-proof shield.

The stator 61 is limited in the oil chamber 12, at least one limiting groove 14 is arranged on the inner wall of the oil chamber 12, a limiting block 611 matched with the limiting groove 14 is arranged on the stator 61, and the stator 61 cannot rotate through the matching of the limiting groove 14 and the limiting block 611. The rotor 62 is disposed on the rotating shaft 30 and opposite to the stator 61. The stator 61 and/or the rotor 62 are wire-connected or copper-bar connected to the terminal block 11. Whether the stator 61 and the rotor 62 are connected to the junction box 11 through wires or not is determined according to the matching type of the stator 61 and the rotor 62, for example, the stator 61 and the rotor 62 form a permanent magnet motor, the rotor 62 is generally a permanent magnet, power connection is not needed, only the stator 62 is connected with power, and then the stator 62 is connected to the junction box 11 through wires. For example, the stator 61 and the rotor 62 constitute a three-phase asynchronous motor, the stator 61 and the rotor 62 both need to be connected to the terminal box 11 by electric wires, and in this case, the rotor 62 generally needs to be connected to the electric brush 64, so that a wiring disc 63 is provided in the oil chamber 12, the wiring disc 63 can be engaged with the limiting groove 14 to prevent rotation, and the electric brush 64 is provided on the wiring disc 63. In addition, a fixing piece for fixing a wire or a copper bar can be further arranged on the wiring disc 63 to avoid interference with the rotation of the rotor 62. In order to facilitate the flowing of the transformer oil, a plurality of oil through holes 631 are further formed in the wiring board 63.

The bearing 40 and the rotor 62 can be limited on the rotating shaft 30 by two shaft clamps, or a step surface is arranged on the rotating shaft 30 and then one shaft clamp is matched to limit the bearing 40 or the rotor 62. The stator 61 may be retained in the oil chamber 12 by a hole clamp. The limiting mode of the components is a mature technology in the field, and the limiting mode is various and is not listed in the scheme.

In order to further improve the fluidity of the transformer oil, at least one oil passing channel 15 extending in the axial direction is provided on the housing 10, the oil passing channel 15 is communicated with the oil chamber 12, and an oil passing groove 21 abutting against the oil passing channel 15 is also provided on the end cover 20 to facilitate the flow of the transformer oil. The oil passage 15 may be a groove, a pipe, or a mixture thereof. Preferably, at least one oil passage 15 of the oil passages 15 is a pipe passage 151, and the inlet and outlet of the two ends of the pipe passage 151 are respectively arranged close to the inlet and outlet of the two ends of the oil chamber 12. The tube passageway 151 may be integrally formed with the housing 10, such as by drilling the tube passageway 151 into the wall of the housing 10, or by direct casting, as shown in FIG. 6; for another example, the duct channel 151 is disposed outside the wall of the housing 10, and the channel wall portion of the duct channel 151 is directly contacted with the outside air to facilitate heat dissipation, as shown in fig. 7, in this case, the port of the duct channel 151 may be communicated with the oil chamber 12 through the oil passing groove 21 (through enlarging the end cover 20 and lengthening the oil passing groove 21), or the duct communicating the duct channel 151 and the oil chamber 12 may be disposed on the housing 10. Furthermore, the tube channel 151 can also be obtained by: a first oil passing hole 152 is formed in one end of the housing 10, a second oil passing hole 153 is formed in the other end of the housing 10, the first oil passing hole 152 and the second oil passing hole 153 are both communicated with the oil chamber 12, the first oil passing hole 152 and the second oil passing hole 153 correspond to each other one by one and are communicated with each other through a pipeline outside the housing 10 to form a pipe passage 151, and a metal pipeline is selected as a pipeline communicated with the first oil passing hole 152 and the second oil passing hole 153, as shown in fig. 8. The latter embodiment of the tube passage 151 is advantageous in that transformer oil can flow through the outside of the housing 10, and the heat dissipation effect can be enhanced to some extent because the metal tube communicating the first oil passing hole 152 and the second oil passing hole 153 is independent of the housing 10. Meanwhile, the first oil passing hole 152 and the second oil passing hole 153 can be used as inlets for filling transformer oil without an additional oil filling port.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.
