Abstract

The utility model discloses a direct drive motor for a sand making machine, which utilizes a permanent magnet synchronous motor (1). An output shaft of the motor is a conical shaft (4), a driving pin slot (3) is arranged on the conical shaft, and the motor is further provided with a mounting flange (2) used for directly mounting the motor onto the sand making machine. When a spindle of the sand making machine is designed into the shape of an inner cone correspondingly, the spindle is directly mounted on the output shaft of the motor in a sleeved manner, the spindle and the output shaft are connected via a driving pin, and the motor is mounted on the sand making machine by the aid of the mounting flange on the motor, so that the output shaft of the motor can be directly connected with the spindle of the sand making machine. The rate frequency of the motor is 66.7Hz, the motor is driven by a frequency converter with an overcurrent protecting function, and the adaptable frequency conversion range is 50-75Hz. In addition, the direct drive motor has the advantages of energy economization, small size, high starting torque, high transmission efficiency, simple structure and convenience in maintenance.

Description

System sand machine direct-drive motor
Technical field
The utility model relates to a kind of motor, is specially the direct-drive motor that mine and harbour system sand machine is used.
Background technology
The common motor that is used on mine and the harbour system sand machine all is based on threephase asynchronous machine at present, and need symmetry to install two simultaneously on every system sand machine with the power asynchronous machine, the mode that motor adopts shaft to install down, as shown in Figure 3, adopt belt pulley (8) transmission between threephase asynchronous machine (7) and the system sand machine main shaft, thereby drive the work of system sand machine.System sand factory is in the process of system sand, and finding this be that the system sand of indirect driving exists a lot of defectives with the threephase asynchronous machine, specifically reduce following some:
1. the efficient of threephase asynchronous machine own is on the low side, and working long hours to waste a large amount of electric energy;
2. the relative energy-saving permanent-magnet synchronous machine of threephase asynchronous machine external form volume is big, and staring torque is little;
3. there is certain coefficient of friction between band and the belt wheel, makes final transmission efficiency comparatively low;
4. be difficult to guarantee that the rotating speed of two threephase asynchronous machines is the same, cause the transmission efficiency of the slow motor of rotating speed to descend fast like this;
5. relatively overall situation is abominable relatively for the on-the-spot dust of system sand, and little sandstone flies between belt and the belt pulley easily, can strengthen the wearing and tearing and the damage of belt and belt pulley like this;
6. the making relative complex of whole system sand system safeguards the comparison difficulty.
The utility model content
In order to overcome above-mentioned defective.The utility model provides a kind of three-phase alternating current system sand machine direct-drive motor, and this motor can be directly installed on the system sand machine and directly drive system sand machine main shaft.The technical scheme that the utility model adopted is: motor adopts permagnetic synchronous motor, and the shaft of motor is a diminished shaft, and a drive pin slot is arranged on this diminished shaft, also has a mounting flange that is used for directly motor being installed on the system sand machine on the motor.
When correspondingly making sand machine main shaft and be arranged to inner conical, and on the awl drive pin slot is set correspondingly also within it, system sand machine main shaft adopts the sleeve form directly to be contained on the shaft of motor like this, the two connects by trundle, by mounting flange on the motor motor is installed and made on the sand machine again, thereby can reach Motor Shaft and the direct-connected purpose of system sand machine main shaft, the transmission between band and the belt wheel has been save in the centre.
As preferred version; the rated frequency of the utility model motor is 66.7Hz, adopts the frequency converter with overcurrent protection to drive, and suitable tuning range is 50-75Hz; under the situation that the motor high load capacity blocks, thereby frequency converter can be cut off the electricity supply automatically because of over current of motor and played protection motor effect.
The beneficial effects of the utility model are:
The utility model system sand machine has following advantage with direct-drive motor:
1. the utility model adopts permagnetic synchronous motor, and the motor rated efficiency is up to 96%, and its efficiency far is higher than threephase asynchronous machine, work long hours to save a large amount of electric energy, and its relative threephase asynchronous machine external form volume is little, and staring torque is big;
2. the utility model is to adopt the structural design that directly drives system sand machine, has saved the process of belt and belt pulley mechanical energy conversion, so not only save cost greatly and also improved transmission efficiency greatly, and simple in structure, easy to maintenance.

Fig. 1 is the structure chart of the utility model system sand machine with direct-drive motor;
Fig. 2 is the application state figure of the utility model system sand machine with direct-drive motor;
Fig. 3 is the structure chart of the threephase asynchronous machine used of common system sand machine.
Among the figure, 1. permagnetic synchronous motor, 2. mounting flange, 3. drive pin slot 4. diminished shafts, 5. system sand machine, 6. system sand machine main shaft, 7. threephase asynchronous machine, 8. belt pulley.
Embodiment
As shown in Figure 1, the utility model adopts permagnetic synchronous motor 1, and the shaft of motor is a diminished shaft 4, and a drive pin slot 3 is arranged on this diminished shaft 4, also has a mounting flange 2 that is used for directly motor being installed on the system sand machine 5 on the motor; As shown in Figure 2, when correspondingly making sand machine main shaft 6 and be arranged to inner conical, and on the awl drive pin slot is set correspondingly also within it, system sand machine main shaft 6 adopts the sleeve form directly to be contained on the diminished shaft 4 of motor like this, system sand machine main shaft 6 and motor diminished shaft 4 refill trundle, the two connects by trundle, by mounting flange on the motor 2 motor is installed on the system sand machine 5 again, thereby can reach Motor Shaft and the direct-connected purpose of system sand machine main shaft, the transmission between band and the belt wheel has been save in the centre.The utility model motor rated frequency is 66.7 hertz, adopts frequency converter to drive, and suitable tuning range is 50 to 75 hertz, and under the situation that the motor high load capacity blocks, thereby frequency converter can be cut off the electricity supply automatically because of over current of motor and played the effect of protection motor.
Above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as the technology contents essence of being made according to the disclosed technical scheme of this patent is identical or any change or the modification that are equal to, all fall into the scope that this patent comprises.
