Description

A kind of direct-drive type winch motor
Technical field
The utility model is related to a kind of direct-drive type winch motor.
Background technology
For many years, ac motor is used as original on the industrial circles such as oil, mine, crane and metallurgical, Ship Propeling Motivation.Typical AC motor design is operated under 1000 to 3000rpm or higher speed.And petroleum machinery, for example twist The plant equipment such as car, top drive are normally operated in relatively low rotating speed, cause to be passed by mechanical reduction box using ac motor Move to reduce the rotating speed of motor.Therefore, for winch drive system, generally include high-speed motor as described above, The deceleration device of mechanical reduction box, increased the cost of system, increased maintenance and requires, increase the number of possible inoperative component And winch drive system main screw lift, volume are increased, but reduce transmission efficiency.
Utility model content
The purpose of this utility model is the shortcoming for overcoming prior art, there is provided a kind of structurally simple, economical property is good, raising Transmission efficiency, long service life, the direct-drive type winch motor for being suitable for low speed direct drive application.
The purpose of this utility model is achieved through the following technical solutions:A kind of direct-drive type winch motor, it include stator, Rotor, winch wallboard and drum shaft, the right part of described stator are fixed on winch wallboard, and the left part of stator is fixed with end Lid, the left part of end cap is provided with fan housing, bearing block A and bearing block B, described rolling is respectively arranged with winch wallboard and end cap One end rotation of cylinder axle is installed in bearing block A, and the other end rotation of drum shaft is installed in bearing block B, is set with drum shaft There is the rotor in stator, ventilation blower is provided with the top of described stator, the air inlet of ventilation blower is connected and position with stator Between winch wallboard and rotor.
The leading section of described stator is provided with terminal box, and terminal box is connected with the lead-out wire of stator.
Described rotor is fixed on drum shaft through expansion set.
Described end cap is fixed on stator through screw.
Air-out window is provided with described end cap.
The utility model has advantages below:The structurally simple, economical property of the utility model is good, improve transmission efficiency, use Long lifespan, be suitable for low speed direct drive application.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
In figure, 1- stators, 2- rotors, 3- winch wallboards, 4- drum shafts, 5- end caps, 6- fan housings, 7- bearing blocks A, 8- bearing Seat B, 9- ventilation blowers, 10- expansion sets, 11- terminal boxes, 12- screws.
Specific embodiment
The utility model is further described below in conjunction with the accompanying drawings, protection domain of the present utility model be not limited to It is lower described:
As shown in figure 1, a kind of direct-drive type winch motor, it includes stator 1, rotor 2, winch wallboard 3 and drum shaft 4, institute The right part of the stator 1 stated is fixed on winch wallboard 3, and the left part of stator 1 is fixed with end cap 5, and end cap is cast steel ZG230- 450, end cap 5 is fixed on stator 1 through screw 12, and the left part of end cap 5 is provided with fan housing 6, divides in winch wallboard 3 and end cap 5 Bearing block A7 and bearing block B8 is not provided with, and one end rotation of described drum shaft 4 is installed in bearing block A7, drum shaft 4 Other end rotation is installed in bearing block B8, and the rotor 2 in stator 1 is set with drum shaft 4.As shown in figure 1, described The top of stator 1 is provided with ventilation blower 9, the air inlet of ventilation blower 9 connected with stator 1 and positioned at winch wallboard 3 and rotor 2 it Between.Ventilation blower 9 can be by peripheral cooling air through in the region between air inlet importing winch wallboard 3 and rotor 2, cooling air is suitable It is secondary to be discharged by gap, the air-out window of end cap 5, fan housing 6 between rotor 2 and stator 1, so as to by the heat band in whole motor Go out, greatly extend service life.
Iron core in described stator 1 is folded by the fanning strip of 50W470T4 high-quality cold-reduced silicon sheet punching and formed, stator 1 Interior punching and tooth support is provided with air vent.Coil in stator by 6 circle specifications for 2-1.75 × 9.5 F46 film wires around System is formed, and straight line portion is repeatedly wrapped with imines film half, and end is repeatedly wrapped with imines film and mica paper tape half, and outsourcing insulation uses nothing The flat bag of alkali glass silk ribbon.Rotor 3 is welded end ring, is effectively expanded whole motor using fine copper ladder row's sliver, four layers of copper coin Area of dissipation.Whole motor temperature can be reduced, its intensity is improved, extends its service life.
The leading section of described stator 1 is provided with terminal box 11, and terminal box 11 is connected with the lead-out wire of stator 1;Described Rotor 2 is fixed on drum shaft 4 through expansion set 10;Air-out window is provided with described end cap 5.
The course of work of the present utility model is as follows:First take two motors and be installed on winch, then at two Connection winch roller between drum shaft 4, drill string is connected on winch drum through steel wire rope, is then passed through alternating current to terminal box 11, Electric current enters in the coil of stator 1 through lead-out wire, and stator 1 drives rotor 2 to rotate, and rotor 2 drives drum shaft 4 to rotate, further Drive winch drum to rotate to be lifted with by drill string.Therefore it is the operation for being capable of achieving 0rpm ~ 500rpm not need mechanical deceleration device Rotating speed, makes structure more simplify, and makes winch drive system main screw lift, small volume, improves transmission efficiency, and the winch motor Performance parameter meets the performance of single motor hoisting gear maximum drill string, increases hoisting power of the winch in constant power area, therefore the electricity Machine is particularly suitable for low speed direct drive.
