Specific embodiment
In the following, with reference to attached drawing and specific embodiment, the utility model is described further, it should be noted that
Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
Polishing motor as shown in Figure 1, including motor housing 1, motor shaft 2 and first end cover 3, the first end cover 3 with
The motor housing 1 is detachably connected, and the first end cap bore 31 passed through for the motor shaft 2, the motor are provided in the first end cover 3
Axis 2 includes 21 and first shaft coupling 22 of shaft body, and the first double-row angular contact bal bearing 4 is provided at the first end cap bore 31,
The shaft body 21 is pierced by out of this motor housing 1 by first double-row angular contact bal bearing 4,22 one end of the first shaft coupling with
The shaft body 21 is detachably connected by the formation of the first screw thread, and first thread rotary orientation is opposite with 2 direction of rotation of motor shaft.This
The polishing motor of utility model at first end cap bore 31 by setting the first double-row angular contact bal bearing 4, and first biserial
Angular contact ball bearing 4 can also bear axial load other than it can bear radial load, so setting can stablize throwing in this way
Halo waves the axial force of generation, so as to improve polishing performance；Other first shaft coupling, 22 one end passes through first with shaft body 21
Screw thread formation is detachably connected, in this way can be to avoid the replacement of whole motor shaft 2, and only needs replacing first shaft coupling 22 i.e.
Can, it greatly facilitates the repair of people and reduces the maintenance cost of people；First screw thread (not shown) rotation direction and motor
2 direction of rotation of axis is on the contrary, setting so not only can be to avoid first shaft coupling 22 when the frictional force generated in polishing process
Abjection can also cause the tighter of the first screw fastening, so as to improve the reliability of polishing motor because of the effect of frictional force instead.
Preferably embodiment, first end cover 3 are detachably connected by the formation of the first bolt with motor housing 1, led to
The connection of the first bolt is crossed, the dismounting of polishing motor can be facilitated, and conducive to maintenance, prevented in addition it can increase pretightning force
It loosens, junction material composition phase transformation will not be caused.Specifically, 22 another end surfaces of the first shaft coupling are provided with the first taper thread
221,221 rotation direction of the first taper thread is opposite with 2 direction of rotation of motor shaft；Because in polishing machine, polishing wheel is generally with cotton piece buff
Based on, the centre bore of cotton piece buff will not be very big, so being equivalent to the effect of a guiding used here as the first taper thread 221, is convenient for
Polishing wheel is mounted on motor shaft 2 by user, in addition, during the use of polishing machine, between polishing wheel and polishing article
Larger frictional force can be generated, this frictional force may be such that polishing wheel deviates from from the motor shaft 2, so here by by
One taper thread, 221 rotation direction is arranged to 2 rotation direction direction of motor shaft on the contrary, can be so that polishing wheel the more turns the more tight, will not be easily
Deviate from from motor shaft 2, ensure that the reliability of polishing machine.
More specifically, by setting clutch shaft bearing outer cover 5, the clutch shaft bearing in 4 outer end of the first double-row angular contact bal bearing
Outer cover 5 can play the role of axially further fix motor shaft 2 so that polishing motor operation it is more stable, and this first
Bearing cover 5 can also play the role of seal protection, prevent first double-row angular contact bal bearing 4 from entering dust and causing to damage
It is bad.
More specifically, polishing motor further includes second end cover 6, which is detachably connected with the motor housing 1,
The second end cap bore 61 that power supply arbor 2 passes through is provided in the second end cover 6, the second biserial is provided at the second end cap bore 61
Angular contact ball bearing 7, the motor shaft 2 are pierced by form both ends by second double-row angular contact bal bearing 7 out of this motor housing 1
The polishing motor of shaft, the motor shaft 2 further include the second shaft coupling 23, which passes through with the shaft body 21
The formation of second screw thread (not shown) is detachably connected, and second thread rotary orientation is opposite with 2 direction of rotation of motor shaft.Same road
Reason, second double-row angular contact bal bearing of polishing motor 7 can also stablize the axial force that polishing wheel waves generation, so as to improve polishing
Performance；Second shaft coupling 23 can also avoid the replacement of whole motor shaft 2, greatly facilitate the repair and reduction of people
The maintenance cost of people；Second screw thread (not shown) rotation direction and 2 direction of rotation of motor shaft on the contrary, equally can to avoid this
Two shaft couplings 23 are deviate from due to the frictional force generated in polishing process.
Second end cover 6 is detachably connected with motor housing 1 by the formation of the second bolt, can equally facilitate polishing motor
Dismounting and maintenance, increasing pretightning force prevents from loosening, and will not cause junction material composition phase transformation.
Second shaft coupling, 23 another end surfaces are provided with the second taper thread 231,231 rotation direction of the second taper thread and motor shaft
2 direction of rotation are on the contrary, the second taper thread 231 here corresponds again to the effect of a guiding, and it is also possible that polishes
Wheel the more turns the more tight, will not deviate from from motor shaft 2 easily, ensure that the reliability of polishing machine.
Second double-row angular contact bal bearing, 7 outer end setting second bearing outer cover 8, similary second bearing outer cover 8 can play
The effect of motor shaft 2 is fixed axially further so that polishing motor is run more stable, and the second bearing outer cover 8 may be used also
To play the role of seal protection, prevent the second double-row angular contact bal bearing 7 from entering dust and damaging.
The above embodiment is only the preferred embodiment of the utility model, it is impossible to be protected with this to limit the utility model
Range, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacing belongs to
In the utility model range claimed.
