Abstract
The utility model discloses a kind of disassembling fixtures of bearing-free motor rotor, including circular pedestal, the center of pedestal is equipped with screw thread hole, two handles are fixed on the periphery of pedestal, described two handles are symmetrical arranged, two U-shaped through-holes are additionally provided on the periphery of pedestal, described two U-shaped through-holes are symmetrical arranged, and disassembling fixture further includes the screw rod being adapted to the screw thread hole.The disassembling fixture of the utility model bearing-free motor rotor, pedestal is fixed on the technique screw hole on permanent magnet machine rotor by U-shaped through-hole with bolt, then screw rod is withstood on by center screw thread hole on the main shaft of helical lobe compressor host, speed reducer or high pressure reciprocating pump, slowly while rotary screw, fix two handles of tooling, so that it may easy removal power down machine rotor.The disassembling fixture of the utility model, manufacturing cost are low, easy to operate efficient.
Description
Technical field
The utility model relates to motor technology fields more particularly to a kind of for bearing-free rare-earth permanent magnet motor rotor
Disassembling fixture.
Background technique
Motor currently on the market is largely using conventional asynchronous motor, and volume is big, and low efficiency, energy consumption is high,
High failure rate need to be regularly maintained.
Rare-earth permanent-magnet electric machine is a kind of novel permanent-magnet motor occurred at the initial stage seventies, due to the high magnetic energy of rare-earth permanent magnet
Long-pending and high-coercive force (especially high intrinsic coercivity), so that rare-earth permanent-magnet electric machine has been more and more widely used.
With the high speed development of rare earth permanent magnet technology in recent years, occurs the permanent-magnet synchronous of a variety of shaftless bearing structures in the market
Motor.Its main feature is that: motor bearing-free itself, by the rotor of magneto directly with helical lobe compressor host, speed reducer or
The main shaft of high pressure reciprocating pump couples, the shell by the shell of motor directly with helical lobe compressor host, speed reducer or high pressure reciprocating pump
Body connection, can greatly reduce motor volume in this way, improve system effectiveness, reduce failure rate, and electromotor no axis holds maintenance.But this
Kind structure is because different with universal architecture, and general tooling can not solve the problems, such as in disassembly process.
Utility model content
In view of the above-mentioned problems, the utility model aim is to provide a kind of disassembling fixture of bearing-free motor rotor, it is convenient
The disassembly of rotor, to solve the problems of the prior art.
To achieve the goals above, the technical solution of the utility model is as follows:
The center of a kind of disassembling fixture of bearing-free motor rotor, including circular pedestal, the pedestal is equipped with screw thread hole,
Two handles are fixed on the periphery of pedestal, described two handles are symmetrical arranged, are additionally provided on the periphery of the pedestal
Two U-shaped through-holes, described two U-shaped through-holes are symmetrical arranged, and the disassembling fixture further includes the screw rod being adapted to the screw thread hole.
A kind of preferred embodiment of the utility model, the handle and the U-shaped through-hole are in 90 ° of angles.
Another preferred embodiment of the utility model, the handle are fixed by welding on the periphery of pedestal.
The disassembling fixture of the utility model bearing-free motor rotor, passing through the U-shaped through-hole on pedestal with bolt when use will
Pedestal is fixed on the technique screw hole on permanent magnet machine rotor, and screw rod is then withstood on screw compression owner by center screw thread hole
On the main shaft of machine, speed reducer or high pressure reciprocating pump, slowly while rotary screw, two handles of tooling are fixed, so that it may light
Rotor is laid down in demolition.The disassembling fixture of the utility model, manufacturing cost are low, easy to operate efficient.
Detailed description of the invention
Fig. 1 is the disassembling fixture structural schematic diagram of the utility model bearing-free motor rotor.
Specific embodiment
In order to be apparent to the technological means and implementation of the utility model, combined with specific embodiments below further
Illustrate the utility model.
Referring to Fig. 1, the disassembling fixture of the utility model bearing-free motor rotor, including circular pedestal 10, pedestal 10
Center is equipped with a larger-diameter screw thread hole 11, is fixed with two one or two by welding manner on the periphery of pedestal 10
Hand 20, the opposite exterior lateral sides of 10 periphery of pedestal are arranged in two handles 20, and two handles 20 are with respect to the central symmetry of pedestal 10
Setting.Two U-shaped through-holes 12 are additionally provided on the periphery of the pedestal 10, two U-shaped through-holes 12 are also with respect to the center pair of pedestal
Claim setting.In the utility model, the angle of U-shaped through-hole 12 and adjacent handle 20 is 90 °.The utility model bearing-free motor rotor
Disassembling fixture, further include the screw rod 30 being adapted to the screw thread hole 11.
The disassembling fixture of the utility model bearing-free motor rotor, passing through the U-shaped through-hole on pedestal with bolt when use will
Pedestal is fixed on the technique screw hole on permanent magnet machine rotor, and screw rod is then withstood on screw compression owner by center screw thread hole
On the main shaft of machine, speed reducer or high pressure reciprocating pump, slowly while rotary screw, two handles of tooling are fixed, so that it may light
Rotor is laid down in demolition.
The advantages of main feature, working method and the utility model of the utility model has been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only the principles of the present invention, the utility model also has respectively on the premise of not departing from the spirit and scope of the utility model
Kind changes and improvements, these changes and improvements are both fallen in the range of claimed invention.
