Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a low-noise parking device that can be used in mechanical parking equipment.

(Prior Art) Noise and vibration of mechanical parking equipment are a big problem. To deal with this problem, conventional measures have been taken, such as sandwiching vibration-proof rubber between the foundation and using an internal steel frame. Figure 2 shows a conventional method of sandwiching vibration-proof rubber between it and the foundation. In the mechanical parking equipment shown in FIG. 2, the rotation of an electric motor 1 is decelerated by a reducer 2 and transmitted to a main shaft 3, and a chain 7 is connected to a sprocket 6 installed on a bearing pedestal 4 and a driven side bearing pedestal 5. The cage 9 on which the car 8 is mounted is rotated. Stopping is performed using the brake 10, but in this method, the vibrations generated by the electric motor 1 and reducer 2 are transferred to the drive system support beam 11 and the foundation 12.
In this method, a rubber isolator 13 is installed between the vibrations to prevent vibrations from being transmitted to the foundation 12 side. However, in this case, since the entire weight of the chain 7, car 8, and cage 9 is applied to the vibration isolating rubber 13, the spring constant of the vibration isolating rubber 13 is extremely high, and therefore, there is a drawback that the vibration isolating effect is not very effective. It was hot.

Next, FIG. 3 shows a conventional method of forming an internal steel frame type. This is a method in which the internal steel frame 15 is erected vertically directly from the ground 14 to propagate generated vibrations directly to the ground. However, the case shown in FIG. 2 does not have much of an anti-vibration effect, and the case shown in FIG. 3 has drawbacks such as high cost.

(Problems that the invention attempts to solve) This invention attempts to solve the problems that conventional mechanical parking equipment has, such as lack of anti-vibration effects and high costs. be.

(Means for solving the problem) For this reason, the present invention has been developed to provide a mechanical parking system in which a vibration isolating rubber is interposed between the foundation and a fixed drive system support beam whose upper surface is installed horizontally. A vibration isolating material is arranged on the upper surface of the system support beam, and a drive system consisting of an electric motor, a reduction gear, etc. is installed on the upper surface of the vibration isolator, and the vibration isolating material is supported by bearing frames erected on both sides of the support beam. , a rubber joint is used for the connection between the bearing frame of the main shaft and the reducer, through which rotation is transmitted through the reducer, and this is used as a means to solve the problem.

(Function) In the above configuration, the vibration isolating material has a vibration damping effect in the x, y, and z directions, and the rubber joint prevents vibrations from being transmitted to the main shaft, and at the same time absorbs misalignment of the shaft center. ing.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings. Fig. 1 shows a drive system portion of a mechanical parking facility according to an embodiment of the present invention. Note that in FIG. 1, the same parts as in FIGS. 2 and 3 are indicated by the same reference numerals. Here, to explain the configuration of the present invention, a vibration isolating rubber 13 is interposed between a foundation 12 and a fixed drive system support beam 11 whose upper surface is installed horizontally.
A vibration damping and isolating material 16 is fixed to the top surface of the vibration damping material 1, and a drive system including an electric motor 1, a reduction gear 2, a brake 10, etc. is installed on the top surface of the vibration isolating material 16. Further, bearing frames 4, 4 are erected on both sides of the drive system support beam 11, and between the frames 4, 4, a main shaft 3 to which rotation is transmitted via a reducer 2 is supported. A rubber joint 17 is installed at the connection portion between the bearing frame 4 and the speed reducer 2. Now, the rotation of the electric motor 1 is reduced by a speed reducer 2 and transmitted to a sprocket 6 attached to a bearing frame 4 via a main shaft 3 connected by a rubber joint 17. The brake 10 is used to stop the vehicle.

(Effects of the invention) As explained in detail above, the invention is constructed so that the vibration isolating material has a vibration damping effect in the three directions of x, y, and z, and the rubber joint is designed to prevent vibration from being transmitted to the main shaft. ing. In conventional drive systems, vibrations that were directly propagated from the electric motor and reducer to the drive system support beam can be avoided by installing a vibration isolating material between the drive system support beam and the drive system in this invention. Direct vibrations from the drive system are absorbed and the conventional vibrations mentioned above can be blocked. In addition, vibrations that have been transmitted from the reducer through the main shaft and bearing frame to the drive system support beam can be blocked by a rubber joint connected to the main shaft. That is, since a rubber joint is used at the connection between the bearing frame and the reducer of the main shaft, which is supported by bearing frames erected on both sides of the drive system support beam and whose rotation is transmitted through the reducer, the reduction It is possible to block vibrations that propagate from the machine to the drive system support beam via the bearing frame. This makes it possible to block vibrations that generate solid-borne sound, and achieve low noise and low vibration mechanical parking equipment. Furthermore, the cost can be significantly reduced compared to the conventional internal steel frame type.
