Description
Technical field
The utility model relates to a kind of two brake motor.
Background technology
The electric single-beam of existing hoisting machinery industry, gourd double-beam, small portal crane, the supporting drive unit of the hoisting machineries such as semi-goliath crane all comprises bridge motor, decelerator, bridge motor and decelerator are split-type structurals, produce the supply of material by different enterprises, secondary assembling again, brake apparatus 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, directly have influence on the performance of whole motor.
Utility model content
The purpose of this utility model is to provide a kind of two brake motor, 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 two brake motors, comprise body, stator, rotor and brake apparatus, described stator, rotor and brake apparatus are all arranged in described body, described brake apparatus comprises tripping spring, sucker, drive sleeve, brake disc and brake strip, described tripping spring, sucker, drive sleeve is connected successively with brake disc, and be all arranged on described rotor, 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(-holder) block and the second brake(-holder) block, described brake strip is arranged in described body, described the first brake(-holder) block is between described the first brake disc and the second brake disc, described the second brake(-holder) block is between described the second brake disc and the 3rd brake disc.
Further, also comprise and be arranged on described epitrochanterian fan, described fan is arranged on the side of described brake apparatus near described engine body exterior.
Further, described rotor is arranged in described body by deep groove ball bearing.
The beneficial effects of the utility model are: the utility model provides a kind of pair of brake motor, brake disc is divided into the first brake disc, the second brake disc and the 3rd brake disc, brake strip is divided into the first brake(-holder) block and the second brake(-holder) block, adopt two modes of braking, improve braking effect, improved overall performance.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of pair of brake motor of the utility model.
In accompanying drawing, the list of parts of each label representative is as follows:
1, body, 2, rotor, 3, stator, 4, tripping spring, 5, sucker, 6, the first brake disc, 7, the second brake disc, 8, the 3rd brake disc, 9, the second brake(-holder) block, 10, the first brake(-holder) block, 11, drive sleeve, 12, fan.
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 two brake motor, comprise body 1, stator 3, rotor 2 and brake apparatus, described stator 3, rotor 2 and brake apparatus are all arranged in described body 1, described brake apparatus comprises tripping spring 4, sucker 5, drive sleeve 11, brake disc and brake strip, described tripping spring 4, sucker 5, drive sleeve 11 is connected successively with brake disc, and be all arranged on described rotor 2, described brake disc comprises the first brake disc 6 setting gradually, the second brake disc 7 and the 3rd brake disc 8, described brake strip comprises and sets gradually the first brake(-holder) block 10 and the second brake(-holder) block 9, described brake strip is arranged in described body 1, described the first brake(-holder) block 10 is between described the first brake disc 6 and the second brake disc 7, described the second brake(-holder) block 9 is between described the second brake disc 7 and the 3rd brake disc 8, due to the effect of tripping spring 4, make the first brake disc 6 and the second brake disc 7 be close to respectively the first brake(-holder) block 10 and the second brake(-holder) block 9, when energising, brake disc is subject to axial tension, and the first brake disc 6 is separated with the second brake(-holder) block 9 with the first brake(-holder) block 10 respectively with the second brake disc 7, in the time of deenergization, axial tension disappears, and is close to respectively the first brake(-holder) block 10 and the second brake(-holder) block 9 because the effect of tripping spring 4 makes the first brake disc 6 and the second brake disc 7, makes complete machine in on-position, reaches the effect of power-off brake.
Also comprise the fan 12 being arranged on described rotor 2, described fan 12 is arranged on the side of described brake apparatus near described body 1 outside.Described rotor 2 is arranged in described body 1 by deep groove ball bearing.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
