Problems solved by technology

The defects caused are: 1. The magnetic field of the DC motor will radiate to the periphery of the tubular motor through the steel pipe, interfere with the control part of the motor, reduce the receiving distance of the remote control, and may cause the failure of the motor control part; 2. The noise of the DC motor and vibration will be transmitted to the running door body through the steel pipe, which will increase the noise and vibration of the running door body

Embodiment Construction

[0011] The present invention will now be described with reference to the drawings and embodiments.

[0012] Such as figure 1 An improved DC tubular motor is shown. One end of the motor shaft 7 of the DC motor 6 arranged in the steel pipe 2 is connected to the reducer 3 through the coupling 4, and the other end of the motor shaft 7 is connected to the brake assembly 8. Two reducing sleeves 51 and 52 made of soft insulating material are respectively provided at both ends of the DC motor, which are used to fix the DC motor 6 in the steel pipe 2. The diameters of the two reducing sleeves 51, 52 are larger than the outer diameter of the DC motor 6. One of the reducing sleeves 52 is fixedly sleeved on the end of the DC motor, and the other reducing sleeve 51 is fixedly sleeved on the DC motor 6 and The connecting part of the coupling 4 provides a certain gap 9 between the DC motor 6 and the steel pipe 2.

[0013] The DC tubular motor of the present invention is also provided with a red...

Abstract

The invention discloses a modified direct current tubular motor. A motor shaft of the direct current motor arranged in a steel pipe is connected with a speed reducer through a coupler, the direct current motor is fixed in the steel pipe through reduction sleeves, one reduction sleeve 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 diameter of each reduction sleeve is smaller than the outer diameter of the direct current motor. The speed reducer is fixed in the steel pipe through a reduction sleeve, the reduction sleeve is fixed at the front end portion of the speed reducer, and the diameter of the reduction sleeve is larger than the outer diameter of the speed reducer. According to the modified direct current tubular motor, the three reduction sleeves are arranged inside the steel pipe to fix the direct current motor and the speed reducer inside the steel pipe, and a certain gap respectively exists among the direct current motor, the speed reducer and the steel pipe. By means of the structure, the output of noise and vibration of the direct current motor can be obviously reduced, and meanwhile a magnetic field of the direct current motor is effectively prevented from radiating to the periphery of the tubular motor.

Description

Technical field [0001] The invention relates to a direct current tubular motor. Background technique [0002] The DC motor in the existing tubular motor directly contacts the steel pipe when the steel pipe is pressed into it, and the output shaft of the DC motor is directly connected with the coupling connected with the reducer. The defects caused are: 1. The magnetic field of the DC motor will radiate to the periphery of the tubular motor through the steel tube, interfere with the control part of the motor, reduce the receiving distance of the remote control, and may cause the malfunction of the motor control part; 2. The noise of the DC motor And vibration will be transmitted to the running door through the steel pipe, which will increase the noise and vibration of the running door. Summary of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides an improved DC tubular motor. The DC tubular motor can reduce the noise and vibration o...
