Abstract

The utility model discloses a gearless transmission system of a running mechanism of a crane. An end of a rotor of a permanent magnet synchronous motor is fixedly connected with a wheel axle, and the other end is fixedly connected with a brake disc; a disk type brake caliper is arranged at the outer edge of the brake disc; and the disk type brake caliper is fixedly connected with a stator. The gearless transmission system of the running mechanism of the crane has the benefits that the problems of high energy consumption, high noise and serious abrasion caused by such transmission as a speed reducer, a speed-changer and the like are solved, the volume is small, the disassembly and the assembly are convenient, the transmission is smooth, and the automation and the digitizing control can be achieved.

Description

The gearless driving system of crane travel mechanism
Technical field
The utility model relates to a kind of motor, especially is applicable to the motor of crane travel mechanism.
Background technology
In the travelling mechanism of crane, motor is connected with reductor by shaft coupling, and drives roller, and its defective is that this gear transmission mode complex structure, volume are big, and transmission 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 the existing travelling mechanism kind of drive, the drive system that provide a kind of gearless connection, transmission 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 travel mechanism, rotor one end of its permanent magnet synchronous motor is fixedlyed connected with axletree, and the other end is fixedlyed connected with brake disc, and the brake disc outer rim is established disc type braking tong, and disc type braking tong is fixedlyed connected with stator.
Further, described permanent magnet synchronous motor drives two roller synchronous operations by power 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 the utility model gearless driving system is, overcome problems such as the energy consumption that transmissions such as reductor, speed changer 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, 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;
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 1
As shown in Figure 1, the gearless driving system of crane travel mechanism, rotor 2 one ends of its permanent magnet synchronous motor are fixedlyed connected with axletree 4, and the other end is fixedlyed connected with brake disc 6, brake disc 6 outer rims are established disc type braking tong 5, and disc type braking tong 5 is fixedlyed connected 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 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 range of the present utility model.
