Abstract
The utility model discloses a seal structure between a rotor shaft and an end cap of a motor. The seal structure comprises the rotor shaft and the end cap. The end cap has a shaft hole, and the rotor shaft is arranged inside the shaft hole. The rotor shaft and the shaft hole of the end cap are arranged with a gap therebetween. The end cap has an oil feeding hole and an oil discharging hole which are communicated with the gap. Sealing rings are arranged on two sides of the oil feeding hole and the oil discharging hole to block the gap, and the gap internally provided with lubricating grease. By adopting the structure, when the rotor shaft is rotated, the lubricating grease lubricates the rotation of the shaft and reduce the friction resistance of the rotor shaft, thereby reducing heat generated by friction and prolonging the service life of the motor; besides, the two sides of the gap are blocked, and foreign matters cannot enter the motor, thereby protecting the motor, and improving the performance of the motor.
Description
Technical field
The utility model belongs to technical field of motors, relates in particular to the armature spindle of motor and the hermetically-sealed construction between end cap.
Background technology
As everyone knows, the armature spindle of motor spreads out of from end cap, can be gapped between armature spindle and end cap.The existence in this gap, can make foreign matter, such as material bits of dust, processing parts etc. enter motor internal, affects the performance of motor.Such structure, the frictional resistance of rotor is larger, and the gap of foreign matter prolonged stay between armature spindle and end cap, also easily causes the wearing and tearing of armature spindle and end cap shaft hole.In addition, the existence in gap also can make the radially vibrations of rotor larger.
Utility model content
For this reason, technical problem to be solved in the utility model is to provide a kind of friction rotor resistance that reduces, and blocking foreign body enters motor internal, reduce the armature spindle of motor of rotor radial vibrations and the hermetically-sealed construction between end cap, the deficiency existing to overcome prior art.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of armature spindle of motor and the hermetically-sealed construction between end cap, comprise armature spindle and end cap, described end cap has axis hole, described armature spindle is positioned at described axis hole, between described armature spindle and the axis hole of end cap, there is gap, it is characterized in that: described end cap has oil filler point and the outage that is communicated to respectively described gap, in described gap, be positioned at described oil filler point and outage both sides have respectively the sealing ring that blocks described gap, in described gap, there is lubricating grease.
Described oil filler point is positioned at the top of described armature spindle vertically, and described outage is positioned at the below of described rotor vertically.
Described outage is positioned at the below of described oil filler point over against ground.
On the aperture of described oil filler point and outage, be provided with stifle.
The position that the shaft hole inner wall of described end cap is positioned at oil filler point and outage both sides has caulking groove, and described sealing ring is positioned at described caulking groove.
Adopt technique scheme, in gap, all have lubricating grease, and shutoff is carried out by sealing ring in both sides; the existence of lubricating grease; when armature spindle rotates, wheel consistent lubricant plays the effect that wheel slide-bar rotates, and reduces armature spindle frictional resistance; thereby reduce friction and produce heat; improve motor useful life, and both sides, gap are by shutoff, foreign matter also cannot enter motor internal; thereby can protect motor, improve the serviceability of motor.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and concrete enforcement, the utility model is elaborated:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the local enlarged diagram in A place of Fig. 1.
In figure:
100-armature spindle, 200-end cap, 201-axis hole, 202-caulking groove, 300-gap, 401-oil filler point, 402-outage, 500-sealing ring.
Embodiment
As shown in Figure 1, the armature spindle of motor of the present utility model and the hermetically-sealed construction between end cap, comprise armature spindle 100 and end cap 200.
Shown in Fig. 2, wherein, end cap 200 has axis hole 201, and armature spindle 100 is positioned at this axis hole 201, between armature spindle 100 and the axis hole 201 of end cap 200, has gap 300.
On end cap 200, there is respectively the oil filler point 401 and the outage 402 that are communicated to gap 300.Oil filler point 401 is positioned at the top that is positioned at vertically armature spindle 100, and 402 of outages are positioned at vertically the below of armature spindle 100 and are right against the position of oil filler point 401.In addition, in gap 300, be provided with two seals circle 500, lay respectively at the both sides of oil filler point 401 and outage 402.Particularly, the position that axis hole 201 inwalls of end cap 200 are positioned at oil filler point 401 and outage 402 both sides has caulking groove 202, and sealing ring 500 is positioned at described caulking groove 202.
On the aperture of oil filler point 401 and outage 402, be provided with stifle (not shown).
Adopt said structure, by the oil filler point 401 on end cap 200 can be to gap 300 interior injection lubricating grease, outage 402 can be discharged lubricating grease unnecessary or that lost efficacy.In the gap of sealed circle 500 sealings in both sides, there is lubricating grease; when armature spindle rotates; wheel consistent lubricant plays the effect that wheel slide-bar rotates; reduce armature spindle frictional resistance, thereby reduce friction, produce heat, improve motor useful life; and both sides, gap are by shutoff; foreign matter also cannot enter motor internal, thereby can protect motor, improves the serviceability of motor.
