During motor shaft occur rocking or mutually stuck phenomenon.
Elastic component is reclined with bearing inner race in the axial direction, and is fixed by Axial Mounting Part, Axial Mounting Part meeting
The pressure of elastic component axial direction is given, elastic component is subject to the extruding of Axial Mounting Part to produce Tension Moment, the inner ring end to bearing
Face produces counteracting force axially and radially.Under the counteracting force axially and radially of elastic component, bearing end-play is sent out
Changing, so as to improve the rigidity of axle, improves dynamic property (noise, vibration and friction), the running accuracy of bearing, it is to avoid
Running middle (center) bearing is stuck, noise problem.
Plain washer can increase the contact area with component, dispersive pressure, protection connected piece；O-ring seal is fixed on axle
The lasso for holding or narrow labyrinth clearance being formed on packing ring, plays a part of to prevent lubricating oil from spilling and foreign object is invaded；Dish
Pad deformability is big, and buffering vibration absorption ability is strong, can bear great load in less space, can be more preferable compared with other packing rings
The rigidity of bearing is improved, reduces the noise of bearing operation.
Used as a kind of above-mentioned improvement of damping type motor of the present invention, there is helicitic texture the shaft end of the motor shaft, the axle
It is screw-type securing member to fixture.The axial restraint of parts on shaft, generally adopts the shaft shoulder, sleeve, nut, shaft end ring.Dish
Shape pad has the anti-loosening property of spring washer, can effectively prevent the loosening of threaded connector.
Used as a kind of above-mentioned improvement of damping type motor of the present invention, the Axial Mounting Part is swivel nut.Swivel nut is a kind of new
The threaded fastener of type, with bonding strength height, antidetonation, shock resistance and anti abrasive function, and energy dispersive stress protect the substrate
Screw thread, greatly prolongs the service life of matrix.Using swivel nut type securing member energy effective protection motor axle thread, and reach vibration damping effect
Really.
Used as a kind of above-mentioned improvement of damping type motor of the present invention, the motor shaft is hollow axle.Divided according to the mechanics of materials
Analysis, in rotating shaft transmitting torque, from terms of radial section, more outward where transmit effective torque effect bigger.Need in rotating shaft
When transmitting larger torque, it is necessary to the thicker diameter of axle.And as the effect in axis part transmission torque is less, so typically
Using hollow-core construction, to reduce the deadweight of rotating shaft.
Advantages of the present invention with effect is：
1st, elastic component is subject to the extruding of Axial Mounting Part to produce Tension Moment, produces axial direction and footpath to the inner ring end face of bearing
To counteracting force, so as to cause bearing end-play to change, so as to improve the rigidity of axle, improve the dynamic of bearing
Performance, it is to avoid running middle (center) bearing is stuck, noise problem.
2nd, using the dish-shaped pad that buffering vibration absorption ability is strong, and elastic fluid is overlapped combination, due to elastic fluid surface
Between frictional resistance effect, absorb impact and dissipation energy effect more notable.
3rd, motor shaft is less in the effect of axis part transmission torque, using core motor axle, can mitigate rotating shaft deadweight,
Make plant running more flexible.
The present invention provides a kind of damping type motor, solves there is radial clearance between the motor shaft of existing motor and bearing,
The problem for causing motor shaft to rock with respect to motor in running.
