The motor is arranged inside the rotary drum, the rotary drum is connected with the shaft through a bearing, the coil of the external rotor motor is placed in an iron core, a rotary drum shaft is hollow, and the cable is led out of the rotary drum shaft to be connected with a control cabinet. When multiple windings are used, multiple cables are also adopted and led to the control cabinet respectively and dependently, the brake systems are distributed on two sides of the rotary drum and can perform braking when being needed. The motor can output large torque at low speed. The rotary drum of the winch device is a motor casing, and the motor is arranged inside the rotary drum. The brake systems are distributed on two sides of the rotary drum and can perform braking.

Description
Technical field
The utility model relates to the winch gear that a kind of low speed permanent magnet synchronous motor directly drives.
Background technology
Winch is one of core component of whole rig or service machine, and its Main Function is drilling, and case in is controlled the pressure of the drill in drilling process, and serves as the speed-changing mechanism of rotating disk or intermediate transmission mechanism and whole rising and put derrick etc.
Traditional winch is by exchanging or DC machine drive gear casing, then by gear case drive roller shaft, version, motor, cylinder, gear case are that order is arranged, so very large of total volume, weight is very heavy, and driving efficiency is low, reliability is also poor.
Summary of the invention
In order to simplify the structure of winch, improve the efficiency of winch, thereby designed the winch gear that a kind of low speed permanent magnet synchronous motor directly drives.That this direct-drive winch has is lightweight, volume is little, energy-efficient, reliability high.
The utility model is that the technical scheme that the problem of solution proposition adopts is: this winch gear is by support, bearing, cylinder, magnet steel, coil, axle, brake system, cable forms, its principal character is: low speed permanent magnet synchronous motor is installed on the support at winch two ends, motor adopts the form of permanent magnetism, cylinder is exactly the shell of permagnetic synchronous motor, the inwall of cylinder is pasted with magnet steel (rare earth permanent-magnetic material) and provides excitation for motor, coil and rotating shaft are built in cylinder, swing roller is connected with axle by bearing, the coil of permagnetic synchronous motor is embedded on iron core, winch axle is hollow, the cable of motor is drawn with control housing and is connected in winch axle, when many cover windings are used, cable is also used many cover cables independently to guide in control housing respectively, cylinder both sides are furnished with brake system, can carry out when needed braking brake.
The winch gear that described a kind of low speed permanent magnet synchronous motor directly drives adopts the direct head roll of external rotor electric machine, and motor is that sinusoidal waveform is controlled, and weak magnetic property is good, has broad speed adjustable range, can adapt to the requirement of winch.
The motor of described winch gear has one or more sets windings, and the triple line of every cover winding all independently picks out control housing, the in the situation that of many cover windings, if there is a set of winding to break down, winch still can rely on other winding to carry out work, can thoroughly not damage, this improves the safety of winch greatly.
The cylinder of described winch gear is exactly the shell of external rotor electric machine, and electric machine built-in is in cylinder, and structure is very compact.
The permagnetic synchronous motor of described winch gear adopts the form of permanent magnetism, may operate under very low speed, exports very high moment of torsion.
The drum shaft of described winch gear is hollow, and the cable of motor wears out from drum shaft.
Brake system is arranged in the cylinder both sides of described winch gear, can carry out braking brake.
The beneficial effects of the utility model are: low speed permanent magnet synchronous motor and winch integrated design, directly head roll, has saved speed reduction gearing, has dwindled the volume of whole winch, has alleviated weight, has improved efficiency, has increased reliability.
