Abstract
The invention provides a compact and deft drive device for cranes and elevators. The drive device includes a three-stage cylindrical gear reducer, a motor flange is connected with the casing of the three-stage cylindrical gear reducer, and the shaft of the motor is connected with the input shaft of the three-stage cylindrical gear reducer.
Description
Technical field
The present invention relates to the actuating device of a kind of hoisting crane and elevator.
Background technology
The actuating device of existing hoisting crane and elevator comprises motor, retarder, and motor shaft links to each other with input shaft of speed reducer.Motor adopts and is arranged on the common electric machine on the motor cabinet, and its volume is big, Heavy Weight.
Summary of the invention
The purpose of this invention is to provide a kind of compact conformation, light and handy hoisting crane and the actuating device of elevator.
The actuating device of this hoisting crane and elevator comprises three grades of cylinder gear speed reducers, and the housing of motor flange and three grades of cylinder gear speed reducers directly connects, and motor shaft links to each other with the input shaft of three grades of cylinder gear speed reducers.
Beneficial effect of the present invention: among the present invention, the direct housing with three grades of cylinder gear speed reducers of motor flange connects, and has simplified connection structure, makes volume of the present invention little, in light weight.
The above-mentioned hoisting crane and the actuating device of elevator, said motor is the variable-frequency motor of band double-faced safety drg.. adopt two braking models, improve use reliability, have bigger safety.
The above-mentioned hoisting crane and the actuating device of elevator, the housing of three grades of cylinder gear speed reducers are Al-alloy casing.Adopt aluminium alloy box (housing), compact conformation, light and handy, attractive in appearance, generous.
Description of drawings
Fig. 1 is a scheme drawing of the present invention.
Fig. 2 is the scheme drawing of three grades of cylinder gear speed reducers.
The specific embodiment
Referring to the hoisting crane shown in Figure 1 and the actuating device of elevator; The variable-frequency motor 2 that comprises three grades of cylinder gear speed reducers 1 and band double-faced safety drg; The flange 21 of motor 2 and the Al-alloy casing 11 of three grades of cylinder gear speed reducers directly connect, and motor shaft links to each other with the input shaft 12 of three grades of cylinder gear speed reducers.
The present invention is the actuating device that is used for the usefulness of hoisting crane and elevator lifting, this product wide application.At present existing hoisting capacity 5
t, 10
t, 20
t, 40
tProduct.
Constructional feature of the present invention:
1. adopt the high-power frequency conversion motor, adjustable speed is to adapt to the demand of different applying working conditions.
2. adopt the helical gear reducer of big speed ratio, have stable drive, function that noise is low.
3. employing aluminium alloy box, compact conformation, light and handy, attractive in appearance, generous.
4. this product weight is light, the transportation finished product is low, efficient is high, has effect energy-conservation, material-saving.
5. compact to design, transmission is simple, and assembling is simple simultaneously.
6. adopt two braking models, improve use reliability, have bigger safety.
7. output shaft adopts invoice serration to connect, and is easy to loading and unloading, unlike the tensioner dish, is difficult to open, not easily assembling.
