Abstract
The utility model discloses a device that instructed at motor magnetism center, including adjusting screw and rotor shaft, the last fixed mounting of adjusting screw has the pointer, is provided with three equidistant recess on the rotor shaft, indicate that needle position is directly over the recess of centre, the utility model discloses the screw rod of an adjustable length of installation on slide bearing, the last fixed pointer of adjusting screw is got on the bus at the rotor shaft and is processed three equidistant recess. After good actual magnetism center is adjusted to the motor, with middle recess on the directional rotor shaft of pointer to the accuracy of magnetism center when this ensures the secondary installation. Confirm the magnetism center when making things convenient for the motor to use on -the -spot installation, avoid the rotor drunkenness to arouse that slide bearing's axle bush temperature risees.
Description
Technical field
The utility model belongs to machine field, the device of particularly a kind of motor magnetic center instruction.
Background technology
The motor of current use sliding bearing, in theory after motor installation, magnetic center position is fixing, and when motor runs, magnetic center position also remains constant.But due to the trueness error of processing, when causing motor to run, magnetic center deviation theory position, thus cause the play of rotor, cause the bearing bush temperature of sliding bearing to raise.
Utility model content
The purpose of this utility model is to provide the device of a kind of motor magnetic center instruction, to solve the motor using sliding bearing, after secondary installing sliding bearing, cannot determine the problem of magnetic center.
For achieving the above object, the utility model is by the following technical solutions:
A device for motor magnetic center instruction, comprises adjusting screw(rod) and armature spindle, described adjusting screw(rod) is installed with pointer, armature spindle is provided with three grooves, and described pointer is positioned at directly over middle groove.
Further, described armature spindle is provided with three equally spaced grooves.
Further, described adjusting screw(rod) is fixed on the sliding bearing above armature spindle by hold-down nut.
Further, described adjusting screw(rod) is the screw rod of the length adjustable of the length that can change self screw rod.
Further, described adjusting screw(rod) is parallel to armature spindle.
Further, described pointer and adjusting screw(rod) are 90 °.
Further, the vertical below of described pointed.
The beneficial effects of the utility model are: the utility model installs the screw rod of an adjustable length on sliding bearing, adjusting screw(rod) are fixed a pointer, Vehicle Processing three equally spaced grooves on armature spindle.After motor regulates actual magnetic center position, by the groove in the middle of on pointed armature spindle, when guaranteeing secondary installing with this, magnetic center position is accurate.Facilitate motor to use during in-site installation and determine magnetic center position; Rotor shifting is avoided to cause the bearing bush temperature of sliding bearing to raise.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein: 1-armature spindle, 2-pointer, 3-adjusting screw(rod), 4-hold-down nut.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of device of motor magnetic center instruction, comprise adjusting screw(rod) 3 and armature spindle 1, described adjusting screw(rod) 3 is installed with pointer 2, armature spindle 1 is provided with three grooves, described pointer 2 is positioned at directly over middle groove.
Described armature spindle 1 is provided with three equally spaced grooves.
Described adjusting screw(rod) 3 is fixed on the sliding bearing above armature spindle 1 by hold-down nut 4.
Described adjusting screw(rod) 3 is the screw rod of the length adjustable of the length that can change self screw rod.
Described adjusting screw(rod) 3 is parallel to armature spindle 1.
Described pointer 2 and adjusting screw(rod) 3 are in 90 °.
Described pointer 2 points to vertical below.
Sliding bearing is installed the screw rod of an adjustable length, adjusting screw(rod) 3 is fixed a pointer 2, Vehicle Processing three equally spaced grooves on armature spindle 1.After motor regulates actual magnetic center position, pointer 2 is pointed to the groove in the middle of on armature spindle 1, when guaranteeing secondary installing with this, magnetic center position is accurate.
Be below preparation method of the present utility model:
1, on sliding bearing, bore a threaded hole, adjusting screw(rod) 3 is assemblied on sliding bearing after loading onto hold-down nut 4, is then fixed on adjusting screw(rod) 3 by pointer 2.
2, to get on the bus out at armature spindle 1 groove at three equidistant intervals.
3, when motor is installed first, first according to theoretical magnetic center position, regulate armature spindle 1 extension elongation, complete final assembly.
4, during electrical power preliminary operation, note measuring armature spindle 1 extension elongation, measuring and calculating magnetic center position offset, determines offset direction.
5, after motor stops, according to magnetic center side-play amount, armature spindle 1 extension elongation being adjusted.
6, adjusting screw(rod) 3 is by adjustment extension elongation, and pointer 2 is aimed at the groove in the middle of on armature spindle 1, adjusting screw(rod) 2 uses hold-down nut 4 to fix.
7, after motor is transported to use scene, only need movable rotor axle 1, guarantee that middle groove is aimed at pointer 2, namely determine magnetic center position.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
