Abstract
The utility model discloses an electromagnetic braking variable-frequency speed regulation three-phase asynchronous motor. The motor comprises a main body motor and an electromagnetic brake arranged at the inner part of the motor and on a rotating shaft of the motor. The motor solves the difficulty that over the years, many mechanisms can not meet accuracy requirement on respects of quick parking and accurate positioning. Simultaneously, by combining a power function mechanism and a brake and position function mechanism as one, the motor changes condition of the separate arrangement of the power function mechanism and the brake and position function mechanism in tradition. Therefore, compared with the condition of the separate arrangement of the power function mechanism and the brake and position function mechanism in tradition, the three-phase asynchronous motor becomes extremely compact in structure, thus greatly reducing occupied useful space and also greatly lowering project investment and cost.
Description
[technical field]
The utility model relates to the motor technology field, particularly a kind of electromagnetic braking frequency control threephase asynchronous.
[background technology]
Along with improving constantly of the level of the productive forces, scientific and technological level and people's desired value level, people are stopped fast to many engineering machinery, and accurately the requirement of location is more more and more higher, and urgent.The electromagnetic braking threephase asynchronous is succeeded in developing under such overall background just.Parking of many engineering machinery in the past and orientation problem majority are to be against special brake mechanism is set outside the motor separately realizes, (be commonly called as belt brake sticking brake mechanism such as band brake, down with), eddy current braking mechanism etc., the useful space that such mechanism's majority takies is big, input is more, cost is higher, and stop fast, accurately locating accuracy more and more is difficult to satisfy the demand.
[utility model content]
The purpose of this utility model is to solve for many years many mechanisms in quick parking, accurately aspect, the location precision technical problem that can not meet the demands.
Another purpose of the present utility model provides a kind of electromagnetic braking frequency control threephase asynchronous and power function mechanism and braking, positioning function mechanism can be united two into one, and changes the situation that traditional power function mechanism and braking, positioning function mechanism set up separately.
In order to achieve the above object, a kind of electromagnetic braking frequency control threephase asynchronous that the utility model provides, it is characterized in that, described motor comprises the main body motor and is arranged at motor interior, is installed on the electromagnetic brake on the shaft of motor, power function mechanism and braking, positioning function mechanism unite two into one, and promptly motor and brake are integrated.。
Described electromagnetic brake is a tray type structure, comprise be used for axle sleeve be fixed in the key of braking in the rotating shaft, by the brake geared sleeve be sheathed on brake on the axle sleeve, at the friction backing plate of described brake one side setting, magnetic bobbin core is arranged at the brake armature of described brake opposite side setting, brake spring and the brake that is connected with described brake armature; Be provided with certain interval between described brake and friction backing plate, the brake armature, the size of brake braking force square, the length of the braking time of motor, mechanism in other words, the accuracy of location, can realize by gap between the brake disc in the regulating brake and friction backing plate, the brake armature, easy and simple to handle, reliable.
Described friction plate adopts high abrasion, withstand voltage, high temperature resistant copper base friction material to make, the adaptive temperature height, and scope wide (300 ℃-800 ℃) can provide powerful braking force for braking, and useful life, replacement cycle all greatly prolong.
Braking moment transmission between described brake and the axle sleeve adopts involute spline (the spline flank profil that is brake disc geared sleeve, axle sleeve is involute shape, the spur gear profile of tooth) mode of paying to carry out.This transmission of torque mode is compared with adopting stressed carry-over moment mode of the single, double key of traditional rectangular and employing rectangular spline carry-over moment mode, its major advantage is: during the spline carry-over moment of spur gear profile of tooth is multiple tooth stressed, the bigger moment of the stressed transmission of the single, double key of comparable traditional rectangular can guarantee that big braking moment transmits reliably.Simultaneously can be more desirable with being designed between brake and the axle sleeve on axis direction, to have, freely, the mated condition of easily sliding, to guarantee the light free clutch of energy between brake disc and friction backing plate, the brake armature, thereby guaranteed brake from, close rapidly, separate thoroughly, action accurately and reliably, steadily do not have and impact, the braking function of brake is able to good realization.In this, also be better than adopting rectangular spline carry-over moment mode.In addition, adopt involute spline to pay carry-over moment, also be better than adopting the stressed carry-over moment mode of the single, double key of traditional rectangular at aspects such as noise, impact, vibrations and adopt rectangular spline carry-over moment mode.
Described brake has the coil insulation structure in the magnetic bobbin core to adopt capsule envelope formula structure, guarantees the reliability of insulating properties of part brake.
Described electromagnetic brake further is provided with manual clutch and disconnects handle, manual clutch disconnects handle and is connected with brake armature, to guarantee that brake is under the out of order state of its supply line, can in time throw off on request between brake disc in the brake and friction backing plate, the brake armature, implement troubleshooting.For timely, the smooth eliminating of fault provides bigger convenience.
Useful technique effect of the present utility model is: the electromagnetic braking threephase asynchronous, from the overall structure aspect, mainly be divided into two parts, and a part is the main body motor portion, another part is the electromagnetic brake part.The main body motor portion is the same with common motor, is bearing electric energy is converted into mechanical energy, the function of the machine torque of output requirement of engineering; Another part, electromagnetic brake are partly being born mechanism are stopped fast, accurately the function of location.That is to say, power function mechanism and braking, positioning function mechanism are united two into one, changed the situation that traditional power function mechanism and braking, positioning function mechanism set up separately.Through years of researches, test, optimal design, this electromagnetic brake that we adopt now is than traditional in the past brake mechanism, such as band brake, eddy current braking mechanism etc., not only in quick parking, the function aspects of accurate location, improve a lot on the precision, for many years many mechanisms have been solved in quick parking, the difficult problem that accurate aspect, location precision can not meet the demands, and also become very compact in configuration aspects, the useful space of occupying also significantly reduces, thereby has also reduced investment, reduced cost.
