According to the driver, the motor and a speed reducer are combined together, and variable speed transmission is realized through the variable speed shaft and the output shaft, so that the whole driver is small in size, compact in structure and fewer in consumed material; and a double-braking manner is adopted, so that the braking effect is improved, and the performance of the whole driver is improved.
Description
Technical field
The utility model relates to a kind of actuator.
Background technology
The supporting actuating devices of elevator machinery such as the electric single-beam of existing elevator machinery industry, gourd double-beam, small portal crane, semi-goliath crane all comprise bridge motor, retarder, but bridge motor and retarder are split-type structurals, by different enterprise produce the supply of material, secondary is assembled again; Existing bridge motor and rise and reuse that its version of retarder is varied, in-use performance respectively has quality, owing to being split-type structural, certain structures repeats, causes that volume is large, Heavy Weight, consumptive material are high.Not only need to consider transmitting ratio, also need to consider the entirety size of retarder and motor, and load-carrying capacity.
On the other hand, brake equipment is indispensable key component on bridge motor, the quality of braking directly has influence on the performance of whole motor, general bridge motor is all that the cooperation of single brake disc and single brake strip completes braking procedure, but in the time of motor long-play, the braking effect of such combination is not fine, has directly had influence on the performance of whole motor.
Utility model content
The purpose of this utility model is to provide a kind of actuator, solves the above-mentioned problems in the prior art.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of actuator, comprise body, transmission system, motor and brake equipment, described transmission system, motor and brake equipment are all arranged in described body, described transmission system comprises variable shaft and output shaft, one end of described variable shaft is connected by gear with the mouth of the main shaft of described motor, the other end of described variable shaft is connected by gear with one end of described output shaft, the other end of described output shaft reaches outside described body, and described brake equipment is arranged on described main shaft.
Further, described brake equipment comprises retarding spring, sucker, drive sleeve, brake disc and brake strip, described retarding spring, sucker, drive sleeve is connected successively with brake disc, and be all arranged on described electric machine main shaft, described brake disc comprises the first brake disc setting gradually, the second brake disc and the 3rd brake disc, described brake strip comprises and sets gradually the first brake plate and the second brake plate, described brake strip is arranged in described body, described the first brake plate is between described the first brake disc and the second brake disc, described the second brake plate is between described the second brake disc and the 3rd brake disc.
Further, also comprise the fan being arranged on described electric machine main shaft, described fan is arranged on the side of described brake equipment near described engine body exterior.
Further, described variable shaft, output shaft and main shaft are all arranged in described body by deep groove ball bearing.
The beneficial effects of the utility model are: the utility model provides a kind of actuator, and motor and retarder are combined, and realize gear by variable shaft and output shaft, make that machine volume is little, compact conformation, consumptive material be few; Adopt two brake mode, improved braking effect, improved overall performance.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of actuator of the utility model.
In accompanying drawing, the list of parts of each label representative is as follows:
1, output shaft, 2, main shaft, 3, retarding spring, 4, sucker, 5, the first brake disc, 6, the first brake plate, 7, the second brake disc, 8, the second brake plate, 9, the 3rd brake disc, 10, fan, 11, drive sleeve, 12, motor, 13, body, 14, variable shaft.
The specific embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, a kind of actuator, comprise body 13, transmission system, motor 12 and brake equipment, described transmission system, motor 12 and brake equipment are all arranged in described body 13, described transmission system comprises variable shaft 14 and output shaft 1, one end of described variable shaft 14 is connected by gear with the mouth of the main shaft 2 of described motor 12, the other end of described variable shaft 14 is connected by gear with one end of described output shaft 1, the other end of described output shaft 1 reaches outside described body 13, and described brake equipment is arranged on described main shaft 2.
Described brake equipment comprises retarding spring 3, sucker 4, drive sleeve 11, brake disc and brake strip, described retarding spring 3, sucker 4, drive sleeve 11 is connected successively with brake disc, and be all arranged on described electric machine main shaft 2, described brake disc comprises the first brake disc 5 setting gradually, the second brake disc 7 and the 3rd brake disc 9, described brake strip comprises and sets gradually the first brake plate 6 and the second brake plate 8, described brake strip is arranged in described body 13, described the first brake plate 6 is between described the first brake disc 5 and the second brake disc 7, described the second brake plate 8 is between described the second brake disc 7 and the 3rd brake disc 9, because making the first brake disc 5 and the second brake disc 7, the effect of retarding spring 3 is close to respectively the first brake plate 6 and the second brake plate 8.In the time that motor 12 is switched on, brake disc is subject to axial tension, and the first brake disc 5 is separated with the second brake plate 8 with the first brake plate 6 respectively with the second brake disc 7; In the time of power cut-off, axial tension disappears, and is close to respectively the first brake plate 6 and the second brake plate 8 because the effect of retarding spring 3 makes the first brake disc 5 and the second brake disc 7, makes complete machine in braking mode, reaches the effect of power-off brake.
