Description
Technical field:
The utility model relates to a kind of shield electric machine general assemblies to test stall fitting device.
Background technique:
With the development of nuclear power technology, the requirement for the process and precision of motor general assembly test is also higher and higher, motor
The quality of general assembly test can directly reflect the end properties of motor, and wherein locked rotor test can simulate and test out motor and exist
When occurring situation in the case where certain power and revolving speed so as to cause stalling, motor internal current in the case where operating voltage
Situation provides strong data for subsequent safeguard procedures.Existing stall tool generally takes a point half formula band bond structure, makes key
Cooperate with shaft key groove, to realize the transmission of torque, achievees the purpose that stall, but nuclear power product is preferably dynamic flat in order to possess
Weigh performance, eliminates the keyway of spindle nose, and in order to equally achieve the purpose that stall, need a kind of new fitting device.
Summary of the invention:
The purpose of the utility model is to provide a kind of shield electric machine general assemblies to test stall fitting device, guarantees locked rotor test energy
The precision for enough smoothly completing and guaranteeing its test, to provide accurate data.The utility model adopts the following technical solution: one
Stall fitting device is tested in kind shield electric machine general assembly, constitutes this tooling by fixed device, intermediate transmission adjustment structure and tapered sleeve (6)
Device；Fixed device is made of connecting plate (1) and fixing bolt (2)；Intermediate transmission adjustment structure is by sleeve (3), limit sleeve
(4), screw (5) forms, and connecting plate (1) middle position has multiple first circular through holes (8), connecting plate two on pitch circle (7)
Side symmetrically has the second circular through hole (9), and fixing bolt (2) passes through the second circular through hole (9) and connecting plate is fixed on stator
On seat (10)；Limit sleeve (4) is fitted in the interior intracavitary of sleeve (3), limit sleeve (4) and sleeve (3) slidable fit, and screw (5) is worn
The threaded hole crossed on connecting plate (1) the first circular through hole of middle position (8) pitch circle identical as sleeve (3) upper end is equipped, tapered sleeve
(6) in the conical internal cavity of sleeve (3), the straight chamber of tapered sleeve (6) holds spindle nose tightly, and limit sleeve (4) is fitted in tapered sleeve (6) top end
On face.
The working principle of the utility model is:
After rotor and stator realize general assembly, all parts of tool are correctly assembled in sequence, tightening screw is just
Sleeve can be lifted up and compress limit sleeve downwards simultaneously, the taper-face contact of sleeve and tapered sleeve is just able to achieve the inner cavity for making tapered sleeve
Space becomes smaller, to hold the spindle nose of rotor tightly；The pretightning force of tightening screw is different, and the frictional force that tapered sleeve realizes spindle nose is just not yet
Together, to meet the torque of its transmission and realize the purpose of stall.
The specifically used process of tool can refer to following example: after rotor and stator realize general assembly, by each portion of tool
Part correctly assembles in sequence, and tightening screw can be lifted up sleeve and compress limit sleeve, sleeve and tapered sleeve downwards simultaneously
Taper-face contact, being just able to achieve makes the intracavity space of tapered sleeve become smaller, to hold the spindle nose of rotor tightly；The pretightning force of tightening screw is not
Together, the frictional force that tapered sleeve realizes spindle nose is also just different, to meet the torque of its transmission and realize the purpose of stall.
The beneficial effects of the utility model are:
The frictional force of stall needs is effectively guaranteed, improves the precision of motor test, reduces workload and work
Time, and can be reduced operating space, the working environment for being suitble to operating space small.Traditional stall mode depends on the transmission of key,
There are the dynamic balancing that keyway influences motor entirety for spindle nose, and the complete demand frictional force of this fitting device, the keyway of spindle nose can take
Disappear, to improve the dynamic balance performance of motor；By changing the pretightning force of bolt, the conical surface between two each components occurs opposite
Sliding is adapted to various experiment conditions to reach different friction force requests.The assembling form slided by the conical surface, is easy to
The size of adjusting force is removed.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model.
Specific embodiment
