Abstract
The invention provides an electric servo direct-drive type walking wheel device which comprises wheels, a front radial bearing, a machine shell, a stator, a rotor, a main shaft, an end cover, a rear radial bearing and an electromagnetic disc brake. After this scheme of adoption, its simple structure, manufacturing, installation and maintenance are convenient for.
Description
Technical Field
The invention relates to the technical field of stereo garages, in particular to an electric servo direct-drive type walking wheel device.
Background
The speed reducer is arranged on the frame of the existing intelligent trolley, the wheels are arranged on the output shaft of the speed reducer, and the motor and the speed reducer are arranged on the frame.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides the electric servo direct-drive type walking wheel device which is simple in structure and convenient to process, manufacture, install and maintain.
In order to achieve the purpose, the technical scheme provided by the invention is as follows: the electromagnetic disc brake comprises a wheel, a front radial bearing, a shell, a stator, a rotor, a main shaft, an end cover, a rear radial bearing and an electromagnetic disc brake, wherein the front radial bearing is arranged at one end of the shell, the rear radial bearing is arranged at the other end of the shell, the stator is installed in the shell, the main shaft is installed in the rotor, one end of the main shaft penetrates through the rear radial bearing to be connected with the electromagnetic disc brake, and the other end of the main shaft penetrates through the front radial bearing to be connected with the wheel.
One end of the shell is provided with an opening, the opening is sealed by an end cover, and the rear radial bearing is arranged in the end cover.
The casing is cylindrical, mounting seats are formed on the side walls of the two sides of the casing in an extending mode, and the length direction of each mounting seat is consistent with the direction of the center line of the casing.
The lower part of the shell is provided with a power interface which is connected with the driver through a cable.
The scheme has the advantages that:
compared with the traditional motor and speed reducer mechanism, the speed reducer is omitted, and the mechanism is simplified;
the front radial bearing and the rear radial bearing are oil-containing bearings with seals, so that a lubricating device is omitted, and the mechanism is a maintenance-free mechanism without lubrication;
thirdly, the structure is compact, the occupied space is small, and the device is particularly suitable for being applied to intelligent trolleys and other devices with small space;
fourthly, a servo control system is adopted, so that the mechanism can be controlled to move accurately and orderly;
fifthly, the structure is simple, and the processing, manufacturing, installation and maintenance are convenient; and because no gear transmission is adopted, the requirement of low noise is completely met.
Drawings

Fig. 2 is a schematic end view of the present invention.
Detailed Description
The invention will be further described with reference to the accompanying drawings, in which preferred embodiments of the invention are: referring to fig. 1 and fig. 2, the electric servo direct-drive traveling wheel device of the embodiment includes a wheel 1, a front radial bearing 2, a housing 3, a stator 4, a rotor 5, a main shaft 6, an end cover 7, a rear radial bearing 8, and an electromagnetic disc brake 9, wherein one end of the housing 3 is sealed, the other end forms an opening, the end cover 7 is installed at the opening, the stator 4 is installed in the housing 3, the housing 3 is cylindrical, mounting seats are formed on the side walls of the two sides of the housing 3 in an extending manner, the length direction of the mounting seats is consistent with the direction of the center line of the housing 3, and a power interface is arranged at the lower part of the housing. A main shaft 6 is arranged in the rotor 5, a front radial bearing 2 is arranged at the sealing end of the casing 3, a rear radial bearing 8 is arranged on the end cover 7, one end of the main shaft 6 penetrates through the rear radial bearing 8 to be connected with an electromagnetic disc brake 9, and the other end of the main shaft 6 penetrates through the front radial bearing 2 to be connected with the wheel 1. The stator 4 of the present embodiment is tightly fixed in the housing 3 and the main shaft 6 is mounted in the rotor 5, fixed in the housing 3 and the end cap 7 by means of two radial bearings 2 and 8. The main shaft 6 is tightly matched with the inner hole of the rotor 5, and the right end of the shaft is provided with an electromagnetic disc brake. The left end of axle is equipped with wheel 1, is equipped with the mount pad on the casing 3, can the direct mount on the base face of intelligent vehicle. If the left side of the machine shell 3 is provided with a flange close to the front radial bearing, the device can also be arranged on a side flange of the intelligent trolley. The lower part of the casing is provided with a power interface which is connected with the driver through a cable. Therefore, the rotating speed and the torque of the rotor 4 (the wheel 1) can be controlled through a set program, and the precise parking position of the intelligent trolley can be controlled through the cooperation of the electromagnetic brake, so that the intelligent trolley is particularly suitable for occasions such as a three-dimensional parking lot.
The above-mentioned embodiments are merely preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, so that the changes in the shape and principle of the present invention should be covered within the protection scope of the present invention.
