Description
Technical field
The utility model relates to a kind of permagnetic synchronous motor, particularly relates to a kind of quill shaft permagnetic synchronous motor.
Background technology
At present, domestic centrifugal cutting machine mechanism actuating force is provided by asynchronous machine mate gear or belt system, the shortcoming of such drive system is complex structure, consumable accessory is many, during machine operation, vibrations are large, and the maintenance of the equipment of giving brings larger difficulty, and need excitation winding due to asynchronous machine rotor, therefore rotating shaft is difficult to make hollow shaft, even if make hollow owing to lacking iron core to strengthen magnetic flux density, efficiency can reduce, like this, tubing, just not by whole asynchronous machine, will use transmission device to change the direction of power usually.
During tubing online production, the tubing of first one-step forming from mould molding out, the temperature of material is in the scope of 190 DEG C-220 DEG C, have to pass through spraying box cooling, in the process, the inside and outside wall of pipeline can adhere to a small amount of cooling water, the particularly residual water of inwall, cannot remove, when tubing is through traction element, when arriving cutting machine fixed length cutting, the residual water of inwall can be flowed out by cutting, and cooling water can be caused like this to flow into motor, corrosion electrical motor structure, also can enter motor inwall and destroy electrical machine insulation degree, even cause burning of motor.
Application number be 200920035419.5 Chinese patent " torque motor with hollow shaft " disclose the solid axis that a kind of hollow shaft replaces general force torque motor to adopt, decrease motor device weight, when processing longer workpiece, the torque motor that hollow shaft can allow workpiece pass through, the main shaft of described torque motor with hollow shaft is hollow shaft, also comprise rotor, stator, front end housing, rear end cap and casing, front and rear cover is fixed by bearing and hollow shaft, casing is fixed by motor anchorage bar and front and rear cover, rotor and stator are arranged between front and rear cover and casing, rotor is fixedly connected with hollow shaft, form inner rotor core, although this utility model can reduce the weight of motor device, and allow workpiece pass, do not need significantly to change hand of cutter to adapt to the position of workpiece, not by the effect length of workpiece, but it does not carry out preservative treatment to motor internal, after a long time use, water on cutting pipes or other materials, easily enter in motor, corrosion electrical motor.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of quill shaft permagnetic synchronous motor, and solve traditional drive system structure complicated, consumable accessory is many, and during machine operation, vibration is large, and cooling water flows into the problem of motor corrosion electrical motor structural member.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme to be achieved:
A kind of quill shaft permagnetic synchronous motor, comprise casing, front end housing, rear end cap, quill shaft, stator core winding and rotor, the described casing left and right sides is fixedly connected with front end housing with rear end cap respectively, described rear end cap is connected with quill shaft by bearing with front end housing, described stator core winding is arranged on internal side of shell, described rotor is arranged on quill shaft, it is characterized in that, on the left of described stator core winding and rear end cap, casing forms the first space, right side and front end housing, casing forms Second gap, sealing material layer is filled with in the first described space and Second gap, and be also provided with sealing material layer between rotor and stator core winding.
The utility model adopts permagnetic synchronous motor to replace asynchronous machine, can realize Brake stop fast, avoids asynchronous machine to send out the transformation of ownership and moves and cause large impact to machinery, ensure stability; And by the setting of quill shaft, also reduce the complexity of conventional cutter structure drive system while alleviating motor weight, when solving machine operation, vibrate large problem; By carrying out encapsulation process in motor, prevent the internal corrosion that hollow shaft design causes; Rotor is fixed on quill shaft, rotor is permanent magnet, during motor rotation, rotor rotates together with quill shaft, becomes a rotating mechanism, tubing in process of production, can through quill shaft, rotor drives centrifugal cutting mechanism, completes the cutting of tubing, whole process cutting rapidly, smooth cut is stingless, smooth movements.
Gap packing matcrial layer around stator core winding, can carry out sealed envelope to it, and in addition, the filling of sealing material layer makes motor internal more compact, and complete machine runs more steady.
Described stator winding is arranged with rotor is mutually corresponding.
The bearing junction of described rear end cap and quill shaft is provided with oil sealing.
During online production tubing, workshop dust is large, noise is high, line speed is fast, during cutting on line tubing, the residual water of its inwall can be flowed out by otch, residual water flows into motor can corrode internal structure, therefore the gap-fill sealing material layer around stator core winding, iron core winding is fully protected, stop dust, the infiltration of oil gas and residual water, prevent corrosion iron core winding, add and be provided with oil sealing in the bearing junction of rear end cap and quill shaft, various sealing is arranged so that the degree of protection of motor key position reaches IP68, the integral protection grade of motor reaches IP66, even if there is a small amount of water to infiltrate, motor still can keep good operating condition, the production of tubing can not be stopped.
Be connected together by the motor centrifugal cutting mechanism and the utility model related to, rotor rotarily drives quill shaft and rotates, thus forms Direct Driving System, centrifugal cutting mechanism is driven to rotate, when reaching preset length, controller starter motor, instantaneous, centrifugal cutting can be completed, such mounting structure eliminates gear on traditional mechanism or pulley drive system, significantly reduces noise, simplifies the structure, beautify outward appearance, save cost.
Compared with prior art; the utility model beneficial effect is: under the prerequisite reducing weight, guarantee usefulness; iron core winding can be protected completely; stop the infiltration of dust, oil gas and residual water; avoid occurring corrosion in motor; the process of preserving and sealing can make complete machine internal structure more compact, increases traveling comfort, simplifies the structure.
