Abstract
The utility model relates to a motor for an electric hoist, which is characterized by comprising a front end cover, a motor shaft, a stator casing, a rotor iron core, a rear end cover, a braking seat, a fan wheel and a fan cover, wherein the front end cover and the rear end cover are respectively fixed at two ends of the stator casing; the motor shaft is arranged on the front end cover and the rear end cover through bearings; the rotor iron core is located in the stator casing and pressed on the motor shaft; a stator iron core is pressed on and located in the stator casing; the stator iron core and the rotor iron core are provided with tapers; the braking seat is arranged on the stator casing; the braking seat and the rear end cover are located on the same end of the stator casing; the braking seat is connected with the motor shaft; the fan wheel is arranged on the motor shaft; the fan cover which is arranged on the stator casing is arranged outside the fan wheel; and the fan wheel is located between the braking seat and the fan cover. The motor for the electric hoist is small in mechanical shock, less in heating and applicable for the electric hoist cranes with various operation requirements.
Description
Technical field
The utility model belongs to technical field of motors, particularly relates to a kind of conical rotor machine that is applicable to electric hoist crane.
Background technology
At present, crane is widely used in fields such as metallurgy, machinery, chemical industry, oil, the energy, has become requisite plant equipment such as various processing factory buildings or warehouse harbour.Electric hoist crane is little because of its volume, be widely used from heavy and light, characteristics such as simple to operate and easy to use.Motor is the critical piece of electric block, is the motive power outputting apparatus of electric block.Because the particularity of many workplaces, the user is high to the performance requirement of electric block in the process of lifting, handling goods.The motor that uses described in the common electric cucurbit is because of reasons such as its tapering are big, make that the mechanical property of rotor is harder, problems such as rotor damage, end ring thawing usually appear, and brake the motor that this rotor of squirrel-cage motor can reach instructions for use as taper, reason because of shell structure, install between itself and the electric block, dismounting and adjust difficulty, so suddenly wait to develop a kind of conical rotor machine that is applicable to electric hoist crane.
Summary of the invention
The utility model provides the conical rotor machine that is applicable to electric hoist crane that a kind of mechanical shock is little, caloric value is few for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of used for electric hoist motor, it is characterized in that: comprise front end housing, motor shaft, stator casing, stator core, rotor core, rear end cap, Brake Block, fan wheel and fan guard, fixedly front end housing and rear end cap respectively on the two ends of described stator casing, described motor shaft by Bearing Installation on front end housing and rear end cap, described rotor core is positioned at the inside of stator casing and is fitted on the described motor shaft, described stator core is fitted on the stator casing and is positioned at the inside of stator casing, described stator core and rotor core are provided with tapering, described Brake Block is installed on the stator casing, described Brake Block and rear end cap are positioned on the same end of stator casing, and Brake Block is connected with motor shaft, described fan wheel is installed on the motor shaft, the outside of fan wheel is provided with the fan guard that is installed on the stator casing, and described fan wheel is between Brake Block and fan guard.
The utility model can also adopt following technical scheme:
The tapering of described stator core and rotor core is 7.1 °-7.2 °.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, be that motor comprises front end housing, motor shaft, stator casing, rotor core, rear end cap, Brake Block, fan wheel and fan guard, described stator core and rotor core are equipped with less tapering.The motor of this structure is compared with existing used for electric hoist motor, has reduced magnetic pull when satisfying detent torque, has so just reduced the impact to bearing and end cap etc., has reduced also that the motor feels hot, motor is operated steadily and does not have the operation of impact.Motor is in operation because of power of motor changes not quite, and temperature rise changes also little, so this kind of motor can be able to use under the voltage range of broad.Motor performance has also improved the usability of electric block when improving.In addition, the structure of motor is applicable to the installation of electric block, be convenient to adjust, and easy accessibility.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, front end housing; 2, motor shaft; 3, stator casing; 4, stator core; 5, rotor core; 6, rear end cap; 7, Brake Block; 8, fan wheel; 9, fan guard.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, a kind of used for electric hoist motor comprises stator casing 3, uses bolt front end housing 1 and rear end cap 6 on the two ends of described stator casing 3 respectively, constitutes the housing of motor with this.Be provided with stator core 4, rotor core 5 and motor shaft 2 in the inside of electric machine casing, described stator core 4 is fitted on the stator casing 3, and described rotor core 5 is fitted on the motor shaft 2.Described stator core 4 is equipped with tapering with rotor core 5, in order to make motor have less magnetic pull, to reduce the hardness of mechanical characteristics of motor, the motor feels hot in minimizing, the tapering of stator core 4 and rotor core 5 is made as 7.1 °-7.2 °, and the tapering of stator core 4 and rotor core 5 was preferably 7.125 ° during this was novel.The two ends of above-mentioned motor shaft 2 are installed in respectively on front end housing 1 and the rear end cap 6 by bearing.A side that is positioned at rear end cap 6 on stator casing 3 is equipped with Brake Block 7 by bolt, and Brake Block 7 is connected with an end of motor shaft 2.An end that connects Brake Block 7 on the motor shaft 2 is equipped with fan wheel 8, is provided with fan guard 9 in the outside of fan wheel 8, and fan guard 9 is by being bolted on the stator casing 3.
The stator core 4 of above-mentioned motor and rotor core 5 have the feature of taper braking squirrel-cage motor, make motor when satisfying detent torque, reduce magnetic pull, so just reduced impact, reduced also that the motor feels hot, motor is operated steadily and do not had the operation of impact bearing and end cap etc.The motor shaft 2 of motor waits other parts and external structure identical with existing taper brake reducing motor, makes this novelly be convenient to adjustment when assemble with electric block, dismounting is easy to maintenance.
