Abstract
The invention relates to a motor shaft replacing tool and a shaft replacing method thereof. A fixing framework of the shaft replacing tool consists of an upper press plate (5), a lower press plate (7) and a pull rod (2), wherein the upper press plate (5) and the lower press plate (7) are symmetrical and are provided with center holes. The diameter of the center holes of the upper press plate and the lower press plate is not smaller than the diameter of a motor rotary shaft. The insides of the upper press plate and the lower press plate are symmetrically provided with clamping pieces (6) which are arranged besides the center holes, and the height of the clamping pieces is higher than a winding end (3) of a motor rotor. The two ends of the pull rod (2) are screws, the one end thereof is assemblingly connected to the screw of the upper press plate or the lower press plate, and the other end thereof passing through the connecting hole of the upper press plate or the lower press plate is connected by the nut (1). The shaft replacing method has the following steps of: sheathing the upper press plate and the lower press plate on the motor rotary shaft from both ends of the rotor through the center holes; clamping a rotor core by the clamping pieces; disassembling an axial positioning circular key from the motor rotary shaft; pressing the motor rotary shaft out; pressing the new motor rotary shaft into the center holes of the lower press plate, the rotor core and the upper pressplate; installing the axial positioning circular key; and disassembling the shaft replacing tool. The invention is convenient to replace the rotary shaft of the motor rotor, is difficult to damage the winding insulation of the motor rotor, and is safe and reliable.
Description
Technical field
The invention belongs to motor and change a technical field.
Background technology
The high-tension winding rotor electric machine is because of its good starting performance, and the application in actual production is comparatively extensive.Because the long-term alternation heavy service of such motor, the bearing of its system, rotating shaft etc. are prone to break down.Bearing breaks down, and changes more or less freely.And rotating shaft because be prone to occur bending and deformation, crack deformation even fracture, these faults appear, can only change rotating shaft.
The rotor structure of high-tension winding rotor electric machine is special, and manufacturing process is handled for earlier rule, insulation and dynamic balancing being carried out in punching again after laminating in the rotating shaft.Prior art is changed axle to the rotor of winding rotor motor; It is structure situation according to rotor; Compress rotor from ventilation hole with bolt, or clamp rotor from interior circle, its clamping, lift, stand up inconvenience is arranged more with clip; And security reliability can not be guaranteed, and very easily causes the damage of winding insulation and falls short of success for lack of final effort.For guarantee repairing the functional rehabilitation of rear motor, in changing a process, it is injury-free to protect original winding insulation, guarantees that the stacking factor of iron core is constant basically, also wants. and easy to setup, lift, stand up, prior art difficulty reaches these requirements.
Summary of the invention
The object of the invention provides a kind of motor rotor shaft of being convenient to change for the deficiency that solves above-mentioned prior art existence just, and easy damaged rotor winding insulation, safe and reliable motor do not change an instrument and change a method.
The objective of the invention is to realize through following technical scheme.
A kind of motor changes an instrument; This changes an instrument and forms fixed frame by the top board that has centre bore and lower platen, the pull bar connection of symmetry; The centre bore aperture of top board and lower platen is not less than the diameter of machine shaft; Be positioned in top board and lower platen inboard that centre bore is other to be symmetrically arranged with holder, the holder height exceeds the rotor winding overhang; The pull bar two ends are screw rod, and the one of which end is connected with the screw on top board or the lower platen is equipped, and the other end passes the connecting hole on lower platen or the top board and passes through nut and connects.
Holder according to the invention is a parallels.Being positioned at the inboard holder of top board and lower platen welds with top board that is abutted and lower platen respectively.Top board and lower platen are provided with hanger.
A kind of motor changes a method, and it is following to change a method:
1. remove the miscellaneous part on the machine shaft, only remaining rotor;
The top board and the lower platen that 2. will change an instrument are set on the machine shaft through centre bore from two ends of rotor, clamp rotor core through holder, and the pull bar two ends are connected with top board and lower platen respectively, through adjusting nut, rotor core are clamped;
3. remove the axial location ring key on the machine shaft, machine shaft is extruded with pressure apparatus;
The machine shaft that 4. will newly change penetrates in the centre bore of lower platen, rotor core, top board, refills the axial location ring key;
5. unclamp nut, take an instrument that changes apart, take off top board and lower platen from machine shaft.
An instrument that changes of the present invention can clamp rotor core, makes rotor core and change to change axle easily after an instrument becomes firm integral body.It is simple to change a tool construction, easy to use, grip roll iron core stable and safe.It is convenient that the present invention changes a method, and easy damaged rotor winding insulation not.
Further set forth content of the present invention below in conjunction with Figure of description.
Description of drawings
Fig. 1 adopts the present invention to change a sketch map of tool changing machine shaft;
Fig. 2 is the left view of Fig. 1.
Embodiment
As shown in the figure; The present invention changes an instrument and comprises the top board that has centre bore 5 of symmetry and adjustable pull bar 2 of lower platen 7, symmetry; Top board 5, lower platen 7, pull bar 2 connect forms stationary frame structure, through the spacing between adjusting yoke 2 scalable top boards and the lower platen.The two ends of present embodiment pull bar 2 are screw rod; The one of which end is connected with the screw on top board or the lower platen is equipped; The other end passes the connecting hole on lower platen or the top board and passes through nut 1 and connects, and is the spacing between scalable top board and the lower platen through adjusting nut.Rotating shaft can not can be passed to guarantee top board and lower platen less than the diameter of machine shaft in the centre bore aperture of top board and lower platen.Be positioned in top board and lower platen inboard that centre bore is other to be symmetrically arranged with holder 6, holder 6 can be selected parallels, and the holder height exceeds rotor winding overhang 3, in order to avoid top board and lower platen are stopped and can not clamp rotor core.Be positioned at the inboard holder 3 of top board and lower platen and fix welding with top board that is abutted and lower platen respectively.Top board and lower platen are provided with hanger 8, so that the lifting when changing spool, stand up.
