Description
Technical field
The present invention relates to a kind of round nut stop washer, particularly to a kind of round spiral shell for rolling bearing locking device
Mother's stop washer.
Background technology
Existing standard round nut stop washer is as it is shown in figure 1, it possesses the effect preventing round nut from loosening, it is impossible to
Retain grease.Height known to front industrial motor manufacturing enterprise, to the center height H160-710 seat No. using rolling bearing
Low-voltage three phase asynchronous motor, for reducing the temperature of bearing, it is to avoid what bearing grease was too much comes off at lower intracavity, strengthens lubrication
Effect, is mounted with that outside rotating shaft upper bearing (metal) oil scraper ring, retention portion are shared in the benefit consistent lubricant.
For using round nut to carry out the motor of bearing inner race location, because being limited by bearing end cover structure, be at bearing
Side increases oil scraper ring, implements relatively difficult, and installs, dismantles inconvenience.
Summary of the invention
The technical problem to be solved in the present invention is for using round nut to carry out the motor of bearing inner race location, how to prevent
Round nut loosens, and retention portion is shared in the benefit consistent lubricant simultaneously.
In order to solve above-mentioned technical problem, the technical scheme is that a kind of round nut stop washer of offer, it is special
Levy and be: include that stop washer body, stop washer body are planar circular structure；Tilt along stop washer body excircle
Stretch out, form an annular cones face；Annularly taper seat cylindrical circumference is perpendicular to axial direction extension, forms one and hangs down
Straight in axial circular planes；To circular planes edge flange, form turnup ring.
Preferably, described annular cones face is provided with the U-shaped stop slotted vane of multiple locking positioning for round nut.
Preferably, described round nut stop washer is shaped by steel plate one punching.
Preferably, described steel plate thickness is 1.5～2.5mm.
Preferably, the axial width of described round nut stop washer is 7～10mm.
Preferably, described round nut stop washer is located between bearing and round nut, the chi of described circular planes external diameter
Very little less than bearing outside diameter size 20～25mm.
Preferably, oil-recovery tank is formed between described circular planes and turnup ring and bearing.
During use, bearing end cover is enclosed within position suitable on machine shaft, passes through frock afterwards bearing press mounting at motor
In rotating shaft, coating bearing grease, install round nut stop washer successively, stop washer round nut is fixed, and assembles end afterwards
Lid, bearing end cover is turned by seam and end cap and is made into one, fixing with bolt.
The inner chamber of bearing end cover is provided with annular oil-recovery tank, and the race diameter of annular oil-recovery tank is equal to or more than in bearing outer ring
Footpath, leaves rational storage area for bearing grease.The inner ring diameter of oil-recovery tank is more than bearing inner race external diameter, oil-recovery tank interior
Circle seam plane is concordant with the bearing plane matched so that in motor operation course, the bearing grease energy that is thrown out of and
In the raceway being back to bearing of Shi Shiliang, it is to avoid the waste of bearing grease, bearing is made to be in all the time in operation process good
Good lubricating status.
For making bearing grease easily be back in the raceway of bearing, round nut is L with the cross section of stop washer oil-recovery tank
Type.The inner ring of bearing end cover is angularly disposed with larger angle, and the slot bottom width of bearing end cover is less than width of rebate.Owing to having one
Fixed inclination angle, and smooth without hindrance, bearing grease is easily back in the raceway of bearing.
The device that the present invention provides overcomes the deficiencies in the prior art, makes the effect of tradition stop washer and oil scraper ring close two
It is one, round nut can not only be played stopping function, also there is retention portion and share in the benefit the effect of consistent lubricant.Simple in construction, easy for installation.
Internal diameter installation dimension, with standard round nut stop washer, the standard round nut stop washer of alternative same model, suitably pushes away
Wide use.

Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is expanded on further.Should be understood that these embodiments are merely to illustrate the present invention
Rather than restriction the scope of the present invention.In addition, it is to be understood that after having read the content that the present invention lectures, people in the art
The present invention can be made various changes or modifications by member, and these equivalent form of values fall within the application appended claims equally and limited
Scope.
The round nut stop washer schematic diagram that Fig. 2 provides for the present embodiment, described round nut stop washer includes
Stop washer body 1, stop washer body 1 is planar circular structure, tilts certain angle along stop washer body 1 excircle
Degree, stretch out a certain distance, forms an annular cones face 2, is perpendicular to axially prolong along annular cones face 2 cylindrical circumference
Extend a certain distance, form one and be perpendicular to axial circular planes 4, circular planes 4 is carried out edge flange, form flange
Ring 5.
Annular cones face 2 is provided with multiple U-shaped stop slotted vane 3, and U-shaped stop slotted vane 3 turns over and is buckled on round nut, is used for justifying spiral shell
Female locking positioning.
Turnup ring 5 can effective retention portion be shared in the benefit consistent lubricant and strengthen the intensity of stop washer body.
The round nut that the present embodiment provides stop washer uses 1.5～2.5mm thick A3 steel plate one punching to shape.Punching
After making type, need to carry out annealing, surface oxidation treatment.
The installation dimension of stop washer body 1 internal diameter need to meet the standard of GB/T858 round nut stop washer.
Circular planes 4 external diameter be smaller in size than bearing outside diameter size 20～25mm.
Whole round nut stop washer axial width is 7～10mm.
When the round nut stop washer that the present embodiment provides uses, it is suitable that bearing end cover 6 is enclosed within machine shaft
Position, rear frock of passing through is fitted in bearing 8 on machine shaft, coats bearing grease 10, installs round nut stop successively
Packing ring 9, stop washer 9 round nut 11 is fixed, and assembles end cap 7 afterwards, and bearing end cover 12 is made into one by seam and end cap 7 turns
Body, fixes with bolt.
The inner chamber of bearing end cover 12 is provided with annular oil-recovery tank, and the race diameter of annular oil-recovery tank is equal to or more than outside bearing 8
Circle internal diameter, leaves rational storage area for bearing grease 10.The inner ring diameter of oil-recovery tank is more than bearing 8 inner ring external diameter, returns
The inner ring seam plane of oil groove is concordant with bearing 8 plane matched so that in motor operation course, the bearing profit being thrown out of
In the raceway being back to bearing that consistent lubricant 10 can be the most appropriate, it is to avoid the waste of bearing grease 10, make bearing at operation process
In be in good lubricating status all the time.
For making bearing grease 10 easily be back in the raceway of bearing 8, the round nut cross section of stop washer 9 oil-recovery tank
L-shaped.The inner ring of bearing end cover 6 is angularly disposed with larger angle, and the slot bottom width of bearing end cover 6 is less than width of rebate.Due to
There is certain inclination angle, and smooth without hindrance, bearing grease 10 is easily back in the raceway of bearing.
Traditional motor bearings enclosing cover round nut stop washer 9 and disc are united two into one by the present embodiment,
In cast inside bearing grease 10 return flow line of bearing end cover 6, leave rational storage area for bearing grease 10, make
Obtain in the raceway being back to bearing 8 that the bearing oil (fat) being thrown out of in motor operation course can be the most appropriate, make axle
Hold 8 in operation process, be in good lubricating status all the time, thus effectively save bearing grease 10, reduce motor
Noise, extends the service life of bearing 8.
