Abstract
The utility model relates to a crane without a speed reducer. All driving motors of a lifting mechanism, a small-vehicle operating mechanism and a large-vehicle operating mechanism of the crane directly adopt the matching use of low-rotation-speed large-torque motors and driving mechanisms. The motors have the soft starting characteristic, do not need to be connected with a starting resistor, can reach the soft starting characteristic through direct power supply, have the speed reduction efficacy per se and have the friction brake at the same time, the brake speed can be regulated, the regulation range of the brake torque is wide, and different brake effects can be obtained. The impact phenomenon generated when the crane is started or stopped can be greatly avoided through being used with the motor, so crane without the speed reducer has good development prospects by using the motors on the crane.

Braking mechanism is disk type brake mechanism or is drum brakes mechanism.
The output speed n=1.2-500r/min of the big torque motor of described slow speed of revolution, output torque=100-30000Nm, degree of protection IP54.
The electrical motor lower end of wheeling mechanism or traveling mechanism of the larger traveller is provided with base, and base is fixed on the tie-beam, and corresponding motor is connected with cooresponding adhesion wheel transmission shaft by coupler.
Brake process to dolly and cart is to enable motor self friction brake equipment to the speed governing of braking scope.
The beneficial effects of the utility model:
1, retarder increases the output torque of common motor and reduces the rotating speed that common motor is exported because car load mechanism no longer needs to install independently, can reduce the power transmission link fully, the control accuracy of the response time of shortening system and raising system has made things convenient for the control operation of hoisting crane.
2, integrated, the flexibility method of designing of the hoisting crane car load driver train of this new model has promptly been saved the space, simplifies the structure again, alleviates complete machine weight on the whole, and profile is succinctly attractive in appearance again.
3, output torque is big, and the loss in efficiency of slowspeed machine is few, overload capacity is strong, running steadily, noise is low, transmission accuracy is high, has reduced the noise that gear impacts, running is steadily and possessed super a cut ability stronger than common speed reduction gearing (machine).Speed error is no more than 0.2r/min.
4, can cost-cutting, increase economic efficiency: under the same power, adopt the indirect drive mechanism of slowspeed machine direct drive mechanism, more can save fund, cost is reduced greatly than common motor+speed reduction gearing (machine).In addition, have simple in structurely, reasonable in design, make easily the advantage of processing, be beneficial to very much promotion and implementation.
