Description
Technical field
This utility model relates to technical field of generators, is specially a kind of without rear bearing band pump alternating current generator.
Background technology
AC generator for vehicle rear bearing is arranged in the bearing chamber of rear end cap, and its effect is to support that rotor exists
In motor freely rotatable.This structure is easy to occur walk the phenomenon of cylindrical by rear bearing, and (bearing outer ring is relative
Bearing chamber produces displacement), make motor failure.AC generator for vehicle rear bearing inner ring is joined with armature spindle interference
Closing, rear bearing outer ring excessively coordinates with bonnet bearing chamber, and work process does not allow bearing to walk cylindrical, but
Owing to bonnet is aluminium diecasting, intensity and the wearability of aluminum are the most poor, it is easy to occur that cylindrical walked by bearing
Phenomenon so that motor failure, especially band pump AC generator for vehicle, once cylindrical walked by rear bearing, just
Oil leakage can be produced, therefore, it is proposed that one is without rear bearing band pump alternating current generator.
Utility model content
The purpose of this utility model is to provide a kind of without rear bearing band pump alternating current generator, above-mentioned to solve
The problem proposed in background technology.
For achieving the above object, this utility model provides following technical scheme: a kind of without the friendship of rear bearing band pump
Stream electromotor, including armature spindle, one end of armature spindle is set with rear end cap, and rear end cap has been embedded in copper sheathing,
This copper sheathing is between armature spindle and rear end cap, and the lower section of copper sheathing is provided with oil sealing, and rear end cap is provided with oil
Line structure, this oil channel structures includes oil-in one, oil-out one, oil-in two and oil-out two, oil-feed
Mouth one connects with oil-out two, and oil-out one connects with oil-in two.
Preferably, the surface of described copper sheathing is provided with oil guide groove and flared lubrication mouth.
Preferably, the lower section of described oil sealing is lined with thin white industrial felt.
Preferably, described armature spindle is provided with oil guiding hole.
Compared with prior art, the beneficial effects of the utility model are: this is without rear bearing band pump alternative electric generation
Machine, utilizes the copper sheathing replacement rear bearing being fixed on inside bonnet, and utilizes the machine inside electromotor vacuum pump
Oil is lubricated between axle and copper sheathing, thoroughly stops the motor failure produced because cylindrical walked by rear bearing
Pattern, copper sheathing surface is provided with oil guide groove and flared lubrication mouth, it is ensured that lubricant effect.Rear end cap is provided with
Oil channel structures, because adding oil circuit on bonnet, proposes higher wanting to the air-tightness of bonnet aluminium diecasting
Ask, and add some and prevent leakage of oil from designing, a copper sheathing oil sealing installed below, below oil sealing again
Thin white industrial felt on pad, thin white industrial felt front and back two block pressur plate is fixed, to reach oil-leakage-prevention
Effect, machine oil enters bonnet against engine oil pump from oil-feed aperture one, and armature spindle has an oil guiding hole,
After rotation, machine oil enters vacuum pump by oil guiding hole on axle, because armature spindle and copper sheathing are matched in clearance, has
A part of machine oil also can be flowed by this gap, it is ensured that lubricant effect, has negative pressure at vacuum pump oil-out one,
Machine oil can be lubricated, then from going out by oil-in two oil guide groove that suck-back enters copper sheathing inside pump
Hydraulic fluid port one is discharged.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is this utility model structure oil channel structures schematic diagram.
In figure: 1 armature spindle, 2 rear end caps, 3 copper sheathings, 4 oil sealings, 5 oil-in one, 6 oil-outs one,
7 oil-in two, 8 oil-outs two.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technology in this utility model embodiment
Scheme is clearly and completely described, it is clear that described embodiment is only this utility model one
Divide embodiment rather than whole embodiments.Based on the embodiment in this utility model, this area is common
The every other embodiment that technical staff is obtained under not making creative work premise, broadly falls into this
The scope of utility model protection.
Referring to Fig. 1-2, this utility model provides a kind of technical scheme: a kind of without the exchange of rear bearing band pump
Motor, including armature spindle 1, armature spindle 1 is provided with oil guiding hole, and one end of armature spindle 1 is set with rear end cap
2, rear end cap 2 has been embedded in copper sheathing 3, and the surface of copper sheathing 3 is provided with oil guide groove and flared lubrication mouth, protects
Card lubricant effect.This copper sheathing 3 is between armature spindle 1 and rear end cap 2, and the lower section of copper sheathing 3 is provided with
Oil sealing 4, the lower section of oil sealing 4 is lined with thin white industrial felt, and rear end cap 2 is provided with oil channel structures, because after
Cover and add oil circuit, the air-tightness of bonnet aluminium diecasting is proposed higher requirement, and adds one
Prevent leakage of oil from designing, copper sheathing 3 oil sealing 4 installed below, has padded again thin Bai work below oil sealing 4
Industry felt, thin white industrial felt front and back two block pressur plate is fixed, to reach the effect of oil-leakage-prevention, this oil circuit
Structure includes oil-in 1, oil-out 1, oil-in 27 and oil-out 28, oil-in 1 with
Oil-out 28 connect, oil-out 1 connects with oil-in 27, machine oil against engine oil pump from
Oil-feed aperture 1 enters bonnet, and armature spindle has an oil guiding hole, and after rotation, machine oil is by oil guiding hole on axle
Entering vacuum pump, because armature spindle 1 and copper sheathing 3 are matched in clearance, some machine oil also can pass through this
Flow in gap, it is ensured that lubricant effect, has negative pressure at vacuum pump oil-out 1, and machine oil can pass through oil-in
27 oil guide groove that suck-back enters copper sheathing 3 inside pump are lubricated, and then discharge from oil-out 1.
Embodiment the most of the present utility model, for the ordinary skill people of this area
