Abstract
The utility model discloses an improved direct-current tubular motor, wherein a motor shaft of a direct-current motor which is arranged inside a steel pipe is connected with a reducer through a coupler. The direct-current motor is fixed inside the steel pipe through reducing sleeves, one of the reduction sleeves is fixed at the tail end of the direct-current motor, the other reduction sleeve is fixed at the connection position of the direct-current motor and the coupler, and the diameters of the reduction sleeves are larger than the outer diameter of the direct-current motor. The reducer is fixed inside the steel pipe through a reducing sleeve which is fixed on the front end portion of the reducer, and the diameter of the reduction sleeve is larger than the outer diameter of the reducer. According to the direct-current tubular motor, three reducing sleeves are arranged inside the steel pipe to fix the direct-current motor and the reducer in the steel pipe and to enable certain gaps to exist among the direct-current motor, the reducer and the steel pipe. By the aid of the structure, noise of the direct-current motor and output of vibration are greatly reduced, and simultaneously, the radiation of a magnetic field of the direct-current motor on the periphery of the tubular motor is effectively avoided.
Description
Technical field
The utility model relates to a kind of direct-current tubular motor.
Background technology
Direct current machine in the existing tube shaped electric machine directly contacts with steel pipe when being pressed into steel pipe, and the output shaft of direct current machine directly is connected with the shaft coupling that is connected with decelerator.The defective that is caused is: 1, the magnetic field of direct current machine can be radiated the periphery of tube shaped electric machine through steel pipe, disturbs the control section of motor, reduces remote controller and accepts distance, and may cause the malfunctioning of Electric Machine Control part; 2, the noise of direct current machine and vibration meeting are delivered to the door body of operation through steel pipe, and the noise of the door body of operation is strengthened with vibration.
The utility model content
To the weak point that exists in the prior art, the utility model provides a kind of improved direct-current tubular motor.This direct-current tubular motor can reduce the noise of direct current machine and the output of vibration, and can avoid the periphery of the magnetic field radiation of direct current machine to tube shaped electric machine.
For realizing above-mentioned purpose, the utility model technical scheme is:
A kind of improved direct-current tubular motor, the motor shaft of being located at the direct current machine in the steel pipe is through the shaft coupling connection reducer.Direct current machine is fixed in the steel pipe through drill holder, and one of them drill holder is fixed in the tail end of direct current machine, and another drill holder is fixed in the connecting portion of direct current machine and shaft coupling, and described drill holder diameter is greater than the external diameter of direct current machine.
Further, decelerator is fixed in the steel pipe through drill holder, and this drill holder is fixed in the leading section of decelerator, and described drill holder diameter is greater than the external diameter of decelerator.
Further, described drill holder is the drill holder of soft insulating material.
The usefulness of technique scheme is:
The utility model direct-current tubular motor is provided with three drill holders direct current machine and decelerator is fixed in the steel pipe in steel pipe; Fixedly two of direct current machine drill holders adopt the socket mode of drill holder diameter greater than the external diameter of direct current machine, make between direct current machine and steel pipe to have certain interval; Fixedly the drill holder of decelerator also adopts the socket mode of drill holder diameter greater than the external diameter of decelerator, makes between decelerator and the steel pipe to have certain interval.After adopting such structure, can obviously reduce the noise of direct current machine and the output of vibration, simultaneously, effectively avoid the periphery of the magnetic field radiation of direct current machine to tube shaped electric machine.
Description of drawings
Fig. 1 is the structural representation of the utility model direct-current tubular motor.
Embodiment
Combine accompanying drawing and embodiment that the utility model is described at present.
A kind of improved direct-current tubular motor as shown in Figure 1, motor shaft 7 one ends of being located at the direct current machine 6 in the steel pipe 2 are through shaft coupling 4 connection reducers 3, and the other end of motor shaft 7 connects brake assembly 8.Be respectively arranged with the drill holder 51,52 of two soft insulating material in the two ends of direct current machine, be used for direct current machine 6 is fixed in the steel pipe 2.Described two drill holders, 51,52 diameters are greater than the external diameter of direct current machine 6; One of them drill holder 52 is fixedly sleeved in the tail end of direct current machine; Another drill holder 51 is fixedly sleeved in the connecting portion of direct current machine 6 and shaft coupling 4, makes between direct current machine 6 and the steel pipe 2 to have certain interval 9.
The utility model direct-current tubular motor also is provided with the drill holder 1 of a soft insulating material in the leading section of decelerator 3, be used for decelerator 3 is fixed in the steel pipe 2.The diameter of this drill holder 1 is greater than the external diameter of decelerator 3, and fixedly sleeved in decelerator 3 leading sections, makes between decelerator and 3 steel pipes 2 to have certain interval 10.
After starting direct current machine 6, the rotating speed of motor shaft 7 passes to shaft coupling 4, and shaft coupling 4 passes to decelerator 3 to rotating speed again and slows down, and the output shaft of decelerator 3 is just exported the suitable slow-speed of revolution.
