Abstract
The invention relates to a gearless transmission system for a crane operation mechanism. In the gearless transmission, one end of a rotor of a permanent magnet synchronous motor is fixedly connected with an axle and the other end of the same is fixedly connected with a brake disc; and a disc type brake calliper is arranged on the outer edge of the brake disc and is fixedly connected with a stator. The gearless transmission system has the following advantages of overcoming the problems of high energy consumption, large noise, large wear and the like caused by the transmission of a speed reducer, a speed changer and the like; and the system has the advantages of small volume, convenience for detachment and stability for transmission, and is beneficial to the realization of automatic and digitalized control.
Description
Technical field
The present invention relates to a kind of electrical motor, especially be applicable to the electrical motor of crane travel mechanism.
Background technology
In the operating unit of hoisting crane, electrical motor is connected with reductor by coupler, and drives roller, and its defective is that this gear transmission mode complex structure, volume are big, and driving efficiency is low, noise is big, moves also steady inadequately.
Summary of the invention
The technical problem to be solved in the present invention is the defective that overcomes existing operating unit type of drive, the driving system that provide a kind of gearless connection, driving efficiency height, operates steadily.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
The gearless driving system of crane travel mechanism, rotor one end of its permasyn morot is captiveed joint with axletree, and the other end is captiveed joint with brake disc, and the brake disc outer rim is established disc type braking tong, and disc type braking tong is captiveed joint with stator.
Further, described permasyn morot drives two roller synchronized operations by transmission shaft, or the gearless driving system is two, drives side wheel operation respectively, and two described gearless driving systems can pass through a Frequency Converter Control.
The beneficial effect of gearless driving of the present invention system is, overcome problems such as the energy consumption that transmissions such as reductor, change-speed box bring is big, noise big, wearing and tearing are big, and volume is little, easy accessibility, and stable drive helps the realization of automation and Digital Control.
Description of drawings
Accompanying drawing is used to provide further understanding of the present invention, and constitutes the part of specification sheets, is used from explanation the present invention with embodiments of the invention one, is not construed as limiting the invention.In the accompanying drawings:
Fig. 1 is the structural representation of gearless driving of the present invention system;
The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the present invention, and be not used in qualification the present invention.
Embodiment 1
As shown in Figure 1, the gearless driving system of crane travel mechanism, rotor 2 one ends of its permasyn morot are captiveed joint with axletree 4, and the other end is captiveed joint with brake disc 6, brake disc 6 outer rims are established disc type braking tong 5, and disc type braking tong 5 is captiveed joint with stator 1.After the startup, rotor 2 drives axletree 4, and roller 3 can drive the complete machine operation.
It should be noted that at last: the above only is the preferred embodiments of the present invention, be not limited to the present invention, although the present invention is had been described in detail with reference to previous embodiment, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
