Abstract

PURPOSE:To provide a geared motor in which noise is reduced by fixing the motor to a machine while damping vibration of the motor. CONSTITUTION:A motor fixing component 13 is disposed through a vibration absorber 14 to the outer peripheral part of a gear case 11 and a frame 17 located on the axis of the armature shaft 16 of an armature 15, i.e., a vibration source. This constitution damps vibration of motor and thereby vibration of counterpart machine effectively thus realizing noise reduction.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-vibration structure for a geared motor used in a power window or the like for raising and lowering window glass of an automobile.

[0002]

2. Description of the Related Art In recent years, a power wind has become a mainstream regulator system in which a wire is wound to move up and down the glass, and the flexibility of the wire is used to directly mount a motor or a set plate of a regulator on which a motor is attached to a door panel. It has a structure to be attached to.

A conventional geared motor will be described below with reference to FIG. In FIG. 3, 1 is a motor gear case, 2 is a set plate screwed to the flange portion 1a of the gear case 1, and has a flange portion 2a attached to a door panel. Reference numeral 3 denotes a housing that houses a drum that winds a wire fitted to the output shaft protruding from the gear case 1, and is assembled to the set plate 2.

[0004]

In such a conventional motor with a gear, the vibration of the motor is transmitted from the gear case 1 to the door panel through the set plate 2 and the flange portion 2a, and the vibration is amplified by the vibration of the door panel to generate noise. It had the problem of becoming large.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems and to provide a geared motor which has a vibration-proof structure so as to prevent the vibration of the motor from being directly transmitted to the door panel and realizes low noise.

[0006]

In order to achieve this object, a geared motor of the present invention is constructed such that a set plate is screwed to a flange portion of a gear case to be assembled with a housing containing a drum, and an armature shaft is It is configured to have a mounting part for mounting a motor on a door panel via a vibration absorber on an outer peripheral portion of an armature shaft of a gear case and a frame which are arranged.

[0007]

With the above construction, by disposing the mounting component for mounting the motor on the door panel via the vibration absorber (for example, rubber) on the outer peripheral portion of the armature shaft of the armature, which is the vibration source of the motor, the space between the motor and the door panel is arranged. Vibration transmission can be effectively blocked.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

The set plate 12 is screwed and assembled to the flange portion 11a of the gear case 11, and the armature 1
The rotational torque generated by No. 5 is transmitted to the drum in the housing 18 via the speed reduction mechanism housed in the gear case 11, the wire is wound, and the window glass is moved up and down.

As described above, the housing 18 containing the set plate 12 and the drum is assembled to form a part of the regulator system, and the flange portion 11a of the gear case 11 is fixed thereto to be integrated with the motor. Become. In the motor integrated with a part of this regulator system, a mounting component 13 is arranged via a vibration absorber 14 at a portion of the gear case 11 and the frame 17 located on the axis of the armature shaft 16. This attachment 1
3 comes into contact with the door panel and is screwed,
A motor integrated with a part of the regulator system will be attached to the door panel.

[0011]

As described above, according to the present invention, the motor integrated with a part of the regulator system is not fixed directly to the door panel, but the gear case and the gear case located on the armature shaft core of the armature of the vibration source. Mounting parts are placed on the outer periphery of the frame via a vibration absorber, and by mounting this on the door panel, the weight of the motor integrated with a part of the regulator system is supported and the vibration of the motor is effectively blocked. In addition, the present invention provides a geared motor that reduces the vibration of the door panel and achieves low noise.

As described above, the housing 18 containing the set plate 12 and the drum is assembled to form a part of the regulator system, and the flange portion 11a of the gear case 11 is fixed thereto to be integrated with the motor. Become. In the motor integrated with a part of this regulator system, a mounting part 13 is arranged via a vibration absorber 14 at a portion of the gear case 11 and the frame 17 located on the axis of the armature shaft 16. This attachment 1

A motor integrated with a part of the regulator system will be attached to the door panel. Clear from Figure 2 (b)
As you can see, the vibration generated by the rotation of the armature
The larger the radius from the axis 16a, the greater the vibration angular velocity.
I hear Therefore, the gear case 1 located on the shaft core 16a
1 and mounting the vibration absorber 14 on the frame 17
The radius can be made small, and it is effective even with a compact vibration absorber
Anti-vibration is possible.
