Description
Technical field
The utility model is related to the technical field of permanent magnet generator, referring in particular to a kind of permanent magnet generator prevents bearing fine motion
The tooling device of abrasion.
Background technology
Bearing is a kind of important spare part in contemporary mechanical equipment.Its major function is the mechanical rotary body of support, is reduced
Friction coefficient in its motion process, and ensure its rotating accuracy.Key components and parts one of of the bearing as wind-driven generator, because
This, needs the lubrication etc. of the type selecting to bearing, the calculating in service life, bearing clearance and bearing to carry out school in the design process
Core.In addition to this, we are also contemplated that unfavorable factor of the extraneous factor to bearing；In generator transport or generator
In storing process, it would be desirable to take fixation to bearing, prevent from causing bearing roller with raceway to occur due to transport
Fretting wear.Fretting wear is the fine motion caused by extraneous vibration, and contact member is only by localized contact load, or bears to fix
Prestressing force.
Invention content
The purpose of the utility model is to overcome the deficiencies in the prior art and disadvantage, it is proposed that a kind of permanent magnet generator prevents
The tooling device of bearing fretting wear can ensure the radial and axial fixation of bearing by the tooling device, effectively avoid axis
The problem of holding fretting wear.
To achieve the above object, technical solution provided by the utility model is：A kind of permanent magnet generator prevents bearing micro-
The tooling device of dynamic abrasion includes the first studdle, the second studdle and cross bracket, wherein the cross
Shape holder is located above the out frame of permanent magnet generator, and by the out frame parallel to each other for being vertically installed at permanent magnet generator
On four first studdles and disk on four second studdles be supported together, and the cross bracket with
The same central shaft of out frame, disk, the disk are removably mounted on the rotor driving method of permanent magnet generator by bolt
Lan Shang, and it is concentric with the rotor drive flange；One end of four first studdles is inserted into the phase of out frame outer ring
It answers in bolt hole, the other end is each passed through four ends of cross bracket, and is fixed using nut；Four second supports
One end of screw rod is welded on disk, and the other end is each passed through four of cross bracket, and close in cross bracket
The heart is fixed using nut.
The cross bracket is formed by channel steel welding.
The utility model compared with prior art, has the following advantages that and advantageous effect：
When generator transports or stores, it can ensure that bearing is radial and axial solid by the utility model tooling device
It is fixed, by the upper and lower position of the studdle nut on adjusting out frame, rotor dead weight can be made to be undertaken by studdle, from
And rotor dead weight is reduced to the pressure of bearing, the damage of bearing is alleviated, while being also effectively guaranteed the radially fixed of bearing,
It effectively prevents since rotor rotation leads to that fretting wear occurs between raceway and ball.In short, new by this practicality
The tooling device of type can be effectively prevented from extraneous unfavorable factor and be damaged caused by bearing, be effectively improved making for bearing
Use the service life.

Steel welding forms, and is located at 4 top of out frame of permanent magnet generator, and is vertically installed at determining for permanent magnet generator by parallel to each other
Four second studdles 2 on four first studdles 1 and disk 5 on handset seat 4 are supported together, and described ten
Font holder 3 and out frame 4,5 same central shaft of disk, the disk 5 are to be removably mounted on permanent magnetism hair by bolt
On the rotor drive flange 6 of motor, and it is concentric with the rotor drive flange 6；One end inserting of described four first studdles 1
In the respective bolt holes of 4 outer ring of out frame, the other end is each passed through four ends of cross bracket 3, and uses nut 7
It is fixed；One end of described four second studdles 2 is welded on disk 5, and the other end is each passed through the four of cross bracket 3
Branch, and close to the center of cross bracket 3, fixed using nut 8.
When generator transports or stores, it can ensure that bearing 9 is radial and axial solid by the utility model tool structure
It is fixed, by the nut upper and lower position of the studdle on adjusting out frame 4, rotor dead weight can be made to be undertaken by studdle,
To reduce rotor dead weight to the pressure of bearing, the damage of bearing is alleviated, while the radial direction for being also effectively guaranteed bearing 9 is solid
It is fixed, it effectively prevents since rotor rotation leads to that fretting wear occurs between raceway and ball.In short, passing through this practicality
Novel tool structure can be effectively prevented from extraneous unfavorable factor and be damaged caused by bearing, be effectively improved bearing
Service life has actual promotional value, is worthy to be popularized.
The examples of implementation of the above are only the preferred embodiment of the utility model, not limit the utility model with this
Practical range, therefore change made by all shapes according to the utility model, principle, it should all cover in the scope of protection of the utility model
It is interior.
