In order to meet the requirements of safety standards, when the woodworking circular saw is finished and the power supply is cut off, the motor needs to be completely stopped within a specified time. In order to meet the above requirements, it is common in the prior art to install a magnetic brake mechanism on the motor. The magnetic brake mechanism is added, so that the manufacturing cost is increased, the electric energy consumption is increased, and the operation cost is increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a motor is provided, this motor not only can satisfy carpenter's circular saw and require safety standard, and make with the running cost low.
In order to solve the technical problem, the utility model relates to a motor, contain the casing, the front end housing, the rear end housing, stator and rotor, the rotor contains the pivot, the iron core, rotor winding, the fan blade, the iron core sets up in the pivot, rotor winding sets up on the iron core, the fan blade sets up on the rear end of pivot, the rear end of pivot passes through the bearing and sets up on the rear end housing, the rear end housing sets up on the rear end of casing, the front end of pivot passes through the bearing and sets up on the front end housing, the front end housing sets up on the front end of casing, still contain the skeleton sealing washer, this skeleton sealing washer suit is at the front end of pivot, and the skeleton sealing washer is located the front end housing, the cavity open end of skeleton sealing washer is towards the terminal surface of front end housing, be full of damping grease in the cavity of skeleton sealing washer.
A gap is reserved between the opening end of the cavity of the framework sealing ring and the end face of the front end cover.
The gap between the cavity opening end of the framework sealing ring and the end face of the front end cover is 0.5-2.5 mm.
The cavity of the framework sealing ring is of a reversed V-shaped structure.
In the motor, the damping grease is filled in the framework sealing tight ring, so that the damping grease is positioned in a space surrounded by the framework sealing ring cavity, the end face of the front end cover and the rotating shaft, and after the motor is powered off, the rotating shaft rapidly stops rotating under the action of the damping grease. The motor can meet the requirement of safety standard only by adopting a mode that the framework sealing tight ring is filled with damping grease, and compared with the prior art which is provided with a magnetizing brake mechanism, the manufacturing and operating cost is greatly reduced.

Fig. 1 is a schematic structural diagram of the motor of the present invention.
Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.
Furthermore, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art. In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.
As shown in fig. 1, the utility model discloses a motor, which comprises a shell 4, a front end cover 10, a rear end cover 2, a stator 3 and a rotor 5. The rotor 5 comprises a rotating shaft 6, an iron core, a rotor winding and fan blades 1, wherein the iron core is arranged on the rotating shaft 6, the rotor winding is arranged on the iron core, and the fan blades 1 are arranged on the rear end part of the rotating shaft 6. The rear end of the rotating shaft 6 is provided on the rear end cover 2 through a bearing, and the rear end cover 2 is provided on the rear end of the housing 4. The front end of the rotating shaft 6 is mounted on a front cover 10 via a bearing, and the front cover 10 is mounted on the front end of the housing 4. The motor further comprises a skeleton sealing ring 7, the skeleton sealing ring 7 is sleeved at the front end portion of the rotating shaft 6, the skeleton sealing ring 7 is located in the front end cover 10, the opening end of the cavity of the skeleton sealing ring 7 faces the end face of the front end cover 10, and damping grease is filled in the cavity 8 of the skeleton sealing ring 7.
In order to further improve the damping effect, a gap is formed between the opening end of the cavity 8 of the framework sealing ring 7 and the end face of the front end cover 10. This allows damping grease to better stay in the gap to improve the damping effect.
In order to further optimize the damping effect, the gap between the opening end of the cavity 8 of the framework sealing ring 7 and the end face of the front end cover 10 is 0.5-2.5 mm.
In order to further improve the damping effect, the cavity of the skeleton sealing ring 7 is of a reversed V-shaped structure, so that the damping grease in the cavity 8 of the skeleton sealing ring 7 can be better adhered to the end face of the front end cover 10 and the rotating shaft 6.
The motor is assembled behind the woodworking circular saw, when the woodworking circular saw is used, the power supply is switched on, the motor is started, and the resistance torque generated by damping grease during starting can be ignored compared with the starting torque of the motor, so that the starting of the motor is not influenced. When the operation is finished, the power supply is turned off, the motor is powered off, the rotating shaft of the motor stops rotating rapidly under the action of the damping grease, and practice proves that the time for stopping rotating the motor is only three fifths of the time required by the safety standard, and is only 5-6 seconds, so that the safety standard requirement is completely met.
The above-mentioned embodiments further describe the objects, technical solutions and advantages of the present invention in detail, it should be understood that the above description is only the embodiments of the present invention, and is not intended to limit the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
