Abstract

The utility model discloses a new type driving unit of middle, high and large tonnage hoisting machinery, which has the key points of: the utility model comprises a box body, a gear wheel shaft, a case cover and a driving motor, the driving motor is a conical rotor wire-wound braking motor; the gear of shaft extension is meshed with the gear of the gear wheel shaft to transmit motive power; the case cover is arranged with sealing ring and connected solidly with the box body with bolts; the shaft gear of the gear wheel shaft 9 is meshed with the gear 19 and through the shaft gear of the gear wheel shaft 1 to output slow speed of revolution, the large torsion is motive power, the case cover is arranged at the opening of the bearing cover; the utility model has the advantages of high starting smoothness, low noise, low energy consumption, long life, small volume and light weight.

Description

High tonnage and hoister in large tonnage actuating device in novel

Technical field

The utility model belongs to the hoisting crane field, specifically high tonnage and the supporting cart actuating device of hoister in large tonnage in electric block double girder crane, small-sized gantry hoisting crane, the new electric single-beam.

Background technology

High tonnage hoisting crane in existing, adopt is used for the hoisting crane actuating device of higher running velocity more, because the operation speed of this actuating device is higher, there is bigger design defect in the lifting of slowly moving for needs, starts the shortcoming that stationarity is poor, noise is big, energy consumption is high, service life is short.

Goal of the invention

The purpose of this utility model is in order to overcome the deficiencies in the prior art, it is a kind of that the spy provides: the actuating device of high tonnage and hoister in large tonnage in electronic being applicable to, it have start the stationarity height, noise is low, energy consumption is little, long service life, little, the lightweight advantage of volume.

Summary of the invention

Main points of the present utility model are: comprise casing, gear wheel shaft, case lid, drive motor; It is characterized in that described drive motor is a cone rotor Wound-rotor type braking motor, the gear on its shaft extension cooperates transmission power with gear on the gear wheel shaft; With bolt the casing leak-tight joint is integral after installing seal ring on the described case lid additional; Shaft gear and gear 19 cooperatings on the gear wheel shaft 9, by the output of the shaft gear on the gear wheel shaft 1 slow speed of revolution, the power of high pulling torque, described case lid is provided with the bearing cap shim installing port.

Advantage and good effect:

1, the utility model propulsion source adopts cone rotor Wound-rotor type braking motor, has increased the continuity and the reliability of actuating device.

2,, can adapt to danger, frangible, slow lifting slowly the land precision instrument of butt joint, the hoisting crane of goods because the utility model has increased multistage at a slow speed speed ratio.

3, little, in light weight, the compact conformation of the utility model volume, the exchange performance is good, easy to maintenance, loss in efficiency is little, moment of torsion is big advantage.

The specific embodiment

In order further to set forth design of the present utility model, be illustrated by description of drawings: back-up ring 13, gear 11, packing ring 12, back-up ring 10, bearing 4 are housed on the gear wheel shaft 9 successively, back-up ring 17, bearing 14, back-up ring 18, singly-bound 15, gear 19, back-up ring 16, bearing 2 are housed on the gear wheel shaft 1 successively; Gear wheel shaft 9 and gear wheel shaft 1 are installed on the casing 8, and make shaft gear and gear 19 gear matched on the gear wheel shaft 9, install packing seal 6 backs on the case lid 5 additional and use bolt 7 with casing 8 leak-tight joints, and bearing 4 adds bearing cap shim 3.

The utility model working process is as follows:

By the power that the motor gear of cone rotor Wound-rotor type braking motor spreads out of, at first pass to gear 11, at the shaft gear that passes through gear wheel shaft 9 successively, gear 19, at last by the required operation torque of the output of the shaft gear on the gear wheel shaft 1.
