Abstract
A gear-free transmission system of a hoisting mechanism of a hoist comprises a permanent magnet synchronous motor; a stator of the permanent magnet synchronous motor is fixed on a frame; a rotor of the permanent magnet synchronous motor is fixedly connected with one end of a winding drum through a brake disc at the end of the winding drum; the other end of the winding drum is fixedly connected with a winding drum shaft through another brake disc; the winding drum shaft is connected with the frame through a bearing; and disk type brake calipers are arranged on the outer edges of the brake discs and are fixed on the frame. The utility model has the benefits that the gear-free transmission system of the hoisting mechanism of the hoist overcomes the defects of large energy consumption, high noise and great abrasion caused by the transmission of a reducer, a transmission and the like, has small volume, is convenient to disassemble and assemble and stable in transmission, and favorably realizes automatic control and digital control.
Description
Technical field
The utility model relates to a kind of electrical motor, especially is applicable to the electrical motor of crane hoisting mechanism.
Background technology
In the lifting mechanism of hoisting crane, electrical motor is connected with reductor by coupler, and drives the reel rotation and realized that lift operations, its defective are that this gear transmission mode complex structure, volume are big, and driving efficiency is low, noise is big, moves also steady inadequately.
The utility model content
The technical problems to be solved in the utility model is the defective that overcomes existing lifting mechanism 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 utility model provides following technical scheme:
The gearless driving system of crane hoisting mechanism, the stator of its permasyn morot is fixed on the frame, and the rotor of permasyn morot is captiveed joint with this end reel by the brake disc of reel one end; The reel other end is captiveed joint with drum shaft by another brake disc, and drum shaft is connected with frame by bearing; The brake disc outer rim is established disc type braking tong, and disc type braking tong is fixed on the frame.
The beneficial effect of the utility model gearless driving 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 utility model, and constitutes the part of specification sheets, is used from explanation the utility model with embodiment one of the present utility model, does not constitute restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of the utility model gearless driving system.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in qualification the utility model.
Embodiment
As shown in Figure 1, the gearless driving system of crane hoisting mechanism, the stator 2 of its permasyn morot is fixed on the frame 1, and its rotor 3 is captiveed joint with this end reel by the brake disc 6-1 of reel 4 one ends; Reel 4 other ends are captiveed joint with drum shaft 5 by another brake disc 6-2, and drum shaft 5 is connected with frame 1 by bearing 8; Brake disc 6-1,6-2 outer rim are established disc type braking tong 7-1,7-2 respectively, and disc type braking tong 7-1,7-2 are individually fixed on the frame 1.
It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although the utility model 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.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
