Abstract
The utility model discloses a crane operation soft-start and brake motor with a cooling function. The crane operation soft-start and brake motor comprises a motor rotating shaft, a motor rear end cover and a brake shell, wherein the brake shell is fixed on the motor rear end cover and is internally provided with a friction disk, one side of the friction disk is in contact with the motor rear end cover, the other side of the friction disk is provided with an armature and an electromagnet in sequence, the armature is connected with a brake spring and an adjusting screw, one end of the motor rotating shaft passes through the motor rear end cover and is connected with the friction disk through a gear sleeve, and the friction disk is provided with fan blades. The friction disk has a cooling function as the fan blades are arranged on the friction disk of a brake, and when the motor is working, the braking effect of the friction disk can be ensured without adding fan components.
Description
Technical field
The utility model relates to the hoisting machinery field, specifically, is a kind of crane operation soft start brake motor that adopts electromagnetic brake structure.
Background technology
The state-of-the-art technology that the brake of crane operation soft start brake motor uses is the direct solenoid structure.When its principle was electrical power, electromagnetic device transferred the alternating current in motor to direct current by a rectifier, produces magnetic force by DC electromagnet, holds armature, and frictional disk separates with back end cover for motor, electric machine rotation.After the motor outage, magnetic force disappears, and armature is under the active force of tripping spring, and pressing friction dish, frictional disk and rear end cap rub and produce moment, and motor stops operating.
The frictional disk excess Temperature, affect braking effect when preventing motor operation, generally needs to install additional on motor fan part.
Summary of the invention
Goal of the invention: the purpose of this utility model is to provide a kind of heat sinking function that carries, in the situation that do not increase the crane operation soft start brake motor that fan part also can guarantee the frictional disk braking effect.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of crane operation soft start brake motor that carries heat sinking function, comprise machine shaft, back end cover for motor and brake shell, described brake shell is fixed on motor rear end and covers, be provided with frictional disk in brake shell, one side of described frictional disk contacts with back end cover for motor, opposite side at frictional disk is provided with armature and electromagnet successively, described armature connects tripping spring and adjustment screw, one end of described machine shaft passes back end cover for motor and is connected with frictional disk by geared sleeve, and described frictional disk is provided with fan blade.
In the utility model, further, described fan blade is arranged on the outer rim of frictional disk.
Beneficial effect: by on the frictional disk of brake, fan blade being set, make frictional disk possess simultaneously heat sinking function, when machine operation, also can not guarantee the braking effect of frictional disk even do not increase the fan part.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is done further and explained.
As shown in Figure 1, the crane operation soft start brake motor that carries heat sinking function of the present utility model comprises machine shaft 1, back end cover for motor 2 and brake shell 5.Brake shell 5 is fixed on back end cover for motor 2, be provided with frictional disk 4 in brake shell 5, one side of frictional disk 4 contacts with back end cover for motor 2, is provided with successively armature 6 and electromagnet 7 at the opposite side of frictional disk 4, and armature 6 connects tripping spring 8 and adjustment screw 9.One end of machine shaft 1 passes back end cover for motor 2 and is connected with frictional disk 4 by geared sleeve 3.Be provided with fan blade 10 on the outer rim of frictional disk 4.
During machine operation, frictional disk 4 breaks away from back end cover for motor 2, does synchronous the rotation with machine shaft 1 under the drive of geared sleeve 3.Because frictional disk 4 is provided with fan blade 10, make frictional disk 4 possess simultaneously heat sinking function, can not guarantee the braking effect of frictional disk 4 even do not increase the fan part yet.
The above is only preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
