Abstract
The utility model provides a kind of drive unit of vaccum bench bag, it comprises the motor being arranged in vaccum bench bag exterior side wall, the speed reducer being connected with motor output shaft, be arranged on the drive sprocket on speed reducer output shaft, and the driven sprocket being in transmission connection by drive chain and drive sprocket, described driven sprocket is arranged on the axle head of worm screw, the two ends shaft extension of described worm screw is connected with the connecting plate being arranged in vaccum bench bag exterior side wall by rolling bearing respectively, described worm screw is meshed with the worm gear being connected on vaccum bench bag external drive main shaft, the endoporus of described worm gear is uniform is provided with three keyways that match with the key in drive main spindle.
Description
Technical field
The utility model belongs to electrolytic aluminium apparatus field, particularly relates to a kind of drive unit of vaccum bench bag.
Background technique
In general, the driving mechanism of vaccum bench bag used for aluminium electrolysis also does circumference operation completely unlike other machineries, but under the drive of motor, drive worm gear, worm mechanism in certain angular range (120 ° of <) to carry out low speed to-and-fro motion by retarder.In worm gear, worm gearing, because the two has different materials and different processing technologys, the material of worm gear mostly is cast iron, and worm screw mostly is carbon steel or low alloy steel, processes after treatment.Mechanical strength and the hardness of worm screw are higher than worm gear, and therefore in use worm gear is more serious than worm screw wearing and tearing.Long term wear will cause worm gear wheel to become short and little, and the engagement capability of forfeiture and worm screw, can only abandon, and has caused the waste of resource.
Model utility content
The purpose of this utility model is exactly the drive unit that just the existing deficiency of above-mentioned prior art is being provided reusable a kind of vaccum bench bag.
The utility model is realized the technological scheme that above-mentioned purpose adopts: a kind of drive unit of vaccum bench bag, it comprises the motor being arranged in vaccum bench bag exterior side wall, the speed reducer being connected with motor output shaft, be arranged on the drive sprocket on speed reducer output shaft, and the driven sprocket being in transmission connection by drive chain and drive sprocket, described driven sprocket is arranged on the axle head of worm screw, the two ends shaft extension of described worm screw is connected with the connecting plate being arranged in vaccum bench bag exterior side wall by rolling bearing respectively, described worm screw is meshed with the worm gear that key is connected on vaccum bench bag external drive main shaft, uniformly in the endoporus of described worm gear or drive main spindle be provided with three keyways that cooperatively interact.
The utility model takes the beneficial effect that technique scheme is brought to be: the utility model is given full play to the utilization efficiency of each gear teeth of worm gear, two-maing ladle while keeping in repair, process respectively the keyway of same size in position, 120 ° of left and right, the existing keyway of worm gear position.Peace, in use according to the abrasion condition of worm gear, is exchanged to mounting point at any time.Extended to like this life cycle of 3 times by original service time, thereby save material service charge, increase the service life.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1, vaccum bench bag; 2, speed reducer; 3, motor; 4, drive sprocket; 5, drive chain; 6, driven sprocket; 7, connecting plate; 8, worm screw; 9, worm gear; 10, drive main spindle.
Embodiment
The utility model is described further below with reference to embodiment and accompanying drawing.
As shown in Figure 1, the drive unit of vaccum bench bag of the present utility model, it comprises the motor 3 being arranged in vaccum bench bag 1 exterior side wall, the speed reducer 2 being connected with motor 3 output shafts, be arranged on the drive sprocket 4 on speed reducer 2 output shafts, and the driven sprocket 6 being in transmission connection by drive chain 5 and drive sprocket 4, described driven sprocket 6 is arranged on the axle head of worm screw 8, the two ends shaft extension of described worm screw 8 is connected with the connecting plate 7 being arranged in vaccum bench bag 1 exterior side wall by rolling bearing respectively, described worm screw 8 is meshed with the worm gear 9 that key is connected on vaccum bench bag 1 external drive main shaft 10, uniformly in the endoporus of described worm gear 9 or drive main spindle 10 be provided with three keyways that cooperatively interact.
