Problems solved by technology

Compared with other motors, due to the different nature of the work, the conical motor used in the driving, first, due to the long working time, short working cycle and high starting frequency, the thrust spring will be distorted, deformed or twisted, resulting in a large braking gap. In case of timely adjustment or brake failure, use failure occurs. If the spring breaks, the motor brake failure will also cause the driving cone motor to burn out in a very short period of time; The sleeve will increase the wear of the bearing, causing the rotor to sink or the deflection of the crankshaft to make the rotor eccentric, causing the motor temperature to be too high. The movement causes the bearing to displace, resulting in sweeping and burning the driving cone motor; therefore, it has a great impact on the safe service life of the driving cone motor

Abstract

The invention discloses a bridge crane conical motor, comprising a housing, a front end cover, and a rear end cover. The motor also comprises a motor shaft. The motor shaft is provided with a conical rotor. The outer ring of the conical rotor is provided with a stator matched with the conical rotor. The motor shaft is rotatably connected with the front end cover and the rear end cover respectively using bearings. The motor shaft is also provided with a part extending out of the rear end cover. The part of the motor shaft, extending out of the rear end cover, is provided with a bridge crane conical motor braking device. Since the part of the motor shaft of the bridge crane conical motor, extending out of the rear end cover, is provided with the bridge crane conical motor braking device, and a technical problem that an original bridge crane conical motor is prone to have friction between the rotor and the stator to burn the bridge crane conical motor is overcome. The bridge crane conical motor realizes to operate safely and stably, operation and maintenance cost of the bridge crane conical motor is reduced, and safe service life of the bridge crane conical motor is improved.

Description

technical field [0001] The invention belongs to the technical field of hoisting machinery, in particular to a driving cone motor. Background technique [0002] In hoisting machinery, motors are already essential driving equipment. At present, conical motors are mostly used in hoisting machinery, and the conical motors mainly include a shell, a motor shaft, a conical rotor set on the motor shaft, a stator matched with the conical rotor set on the outer ring of the conical rotor, and a set at one end of the motor shaft. The fan brake wheel, the friction plate set on the outer ring of the fan brake wheel, the thrust spring, the support sleeve, and the thrust bearing; the start and brake of the cone motor are installed on the fan of the cone motor. In the state, the friction plate on the fan is tightly combined with the friction surface on the end cover by a thrust spring, so that the conical motor is in the brake stop state; when the conical motor is energized and working, the...
