Generally speaking, retainer is very crucial part of rolling bearing, and the performance of retainer has determined the Performance And Reliability of rolling bearing to a great extent.This be because, in use, the performance of retainer not only will be born the influence of mechanical stresses such as friction force, tension force and inertial force, but also to be subjected to from chemical corrosion effects such as lubricant, organic solvent or cooling mediums, its performance can be along with the difference of working condition difference to some extent, such as meeting along with the height of temperature, the size and the vibration force in the work of shock load change and change.
In order to satisfy the requirement of rolling bearing work, rolling bearing retainer adopts injection molding forming method to make more now, assembling for the ease of rolling bearing, often retainer is made single face, it is the face that retainer only covers the rolling bearing rolling body, at the rolling bearing another side, the rolling bearing rolling body exposes.Yet in process of production, the retainer regular meeting of single face is because array of procedures, managerial former thereby disappearance or lack; Clean in addition in the operation of rolling bearing, the situation that retainer and rolling bearing break away from also can take place.For fear of rolling bearing retainer disappearance, current generally after the bearing matting, adopt artificial method that rolling bearing is checked, promptly assign the special messenger to check whether rolling bearing retainer lacks.But hand inspection has certain fault rate on the one hand, also is unfavorable for the robotization that rolling bearing is produced on the other hand, is unfavorable for the reduction of rolling bearing production cost.
Summary of the invention
The deficiency that whether lacks at current manual detection rolling bearing retainer, the objective of the invention is to, a kind of method whether rolling bearing retainer lacks that detects is provided, whether this method can detect rolling bearing retainer and lack, reduce error to greatest extent, and can improve the production automation degree of rolling bearing.
The method whether detection rolling bearing retainer provided by the invention lacks comprises:
Steps A makes rolling bearing should have the retainer one side relative with the photoinduction sensor;

Embodiment
Below in conjunction with accompanying drawing method provided by the invention is described in detail.
Whether the photoinduction sensor that the method whether detection rolling bearing retainer provided by the invention lacks can utilize looking on the greasing gland machine a little to recognize in the face device lacks retainer and detects.Therefore, at first rolling bearing greasing and greasing gland machine are simply introduced.
Greasing is an important procedure of Production of bearing, for the maintenance of bearing, safeguard to have vital role.For the rolling bearing that adopts single face, injection mo(u)lding retainer, its rolling body only simultaneously exposes at rolling bearing, and the retainer that another side is injection molding moulding covers; Therefore, to carry out in the one side that rolling body exposes the rolling bearing greasing.In order to improve the automaticity that rolling bearing is produced, generally use the greasing gland machine to the rolling bearing greasing, the greasing gland machine is the machinery and equipment that the rolling bearing after being used for assembling finished carries out greasing.The greasing gland machine comprises shipping platform, looks for and a little recognize face device, turning device, grease pouring device and grease testing fixture, and described rolling bearing shipping platform can transmit rolling bearing between a plurality of working positions; The described function of a little recognizing the face device of looking for is to judge that whether up one side that the rolling body on the rolling bearing shipping platform exposes, if up, just directly carry out greasing to rolling bearing with grease pouring device; Therefore if not up, because retainer only covers the one side of rolling body, another side exposes certainly, with described turning device rolling bearing is overturn, and what make that rolling body exposes one faces up, and uses described grease pouring device to the rolling bearing greasing again; After the greasing, check with described grease testing fixture whether the grease of being annotated in the rolling bearing is qualified.Look for and a little recognize the one side that the face device judges that the rolling bearing rolling body exposes and whether realize by a photoinduction sensor up, when judging, the photoinduction sensor can be launched light beam, when light beam irradiates to rolling body, because rolling body is a rotary body, its catoptrical strong and weak difference can be bigger, and the photoinduction sensor can produce corresponding signal according to the bigger reflected light of strong and weak diversity ratio; When light beam irradiates arrived retainer or neutral gear, catoptrical strong and weak difference was little, and the photoinduction sensor can produce another kind of corresponding signal according to the little reflected light of strong and weak difference.Under both of these case, the unlike signal that the photoinduction sensor produces can be determined the location status of rolling bearing, has both judged that whether one side that rolling body exposes was towards top.More than describe as can be seen, look for and a little recognize the face apparatus function and be to judge and judge that whether one side that rolling body exposes is towards top, for the rolling bearing greasing provides prerequisite smoothly.
The present invention can utilize the above-mentioned photoinduction sensor of a little recognizing in the face device of looking for to carry out the detection whether rolling bearing retainer lacks, and as shown in Figure 1, the method that embodiment one provides comprises:
Step S101 makes rolling bearing should have the retainer one side relative with the photoinduction sensor.When the one side of exposing when the rolling bearing rolling body was relative with the photoinduction sensor, the photoinduction sensor was certain to be radiated on the rolling body, and the photoinduction sensor will be sensed reflected light and just have bigger strong and weak difference; No matter whether rolling bearing retainer lacks, and the one side that the photoinduction sensor exposes at rolling body is responded to can produce identical result, and therefore, the one side of exposing at rolling body with the light induction pick-up is responded to and be can not determine whether retainer lacks.And the one side of exposing when the rolling bearing rolling body is not relative with the photoinduction sensor, and the photoinduction sensor is responded to the purpose that just can reach detection to the one side that retainer should be arranged; In this case, when retainer existed, because retainer covers rolling body, because retainer is injection molded, the reflected light of retainer did not just have bigger strong and weak difference, and the photoinduction sensor just can induce corresponding signal; If retainer disappearance, light beam will shine on the rolling body on the photoinduction sensor, and the reflected light of rolling body just has bigger strong and weak difference, and the photoinduction sensor will induce another kind of signal, therefore, need make rolling bearing should have the retainer one side whether relative with the photoinduction sensor.Certainly, be conclusion after judging because whether retainer lacks, therefore can be opposing with the photoinduction sensor by confirming that rolling body expose one side, making have the retainer one side relative with the photoinduction sensor.
Step S102 makes the axis rotation of photoinduction sensor around rolling bearing, and simultaneously, the photoinduction sensor is launched light beam to rolling bearing, and makes light beam irradiates between rolling bearing inner ring and outer ring.A little recognize in the face device looking for of greasing gland machine, the photoinduction sensor is positioned at the top of transmission platform; Look for when a little recognizing the face station when rolling bearing is transferred on transmission platform, the photoinduction sensor just in time is positioned at the rolling bearing top; The light beam of photoinduction sensor emission with lie in transmission platform on rolling bearing parallel axes or substantially parallel, the photoinduction sensor just can be the axle rotation with the axis of rolling bearing like this, in rotation, the photoinduction sensor emission goes out light beam, light beam irradiates is between the inner ring and outer ring of rolling bearing, along with photoinduction sensor rotation, the point of irradiation of light beam also can move between the inner ring of rolling bearing and outer ring.
Step S103 judges whether the light beam of photoinduction sensor emission shines rolling body, if then enter step S104; If not, then enter step S105.When the relative rolling bearing of light beam rotated, if retainer does not exist, light beam will shine on the rolling body, and the reflective light intensity weakly heterogeneous that reflexes to the photoinduction sensor will be very big, and the photoinduction sensor will produce corresponding signal; If retainer exists, light beam just can not shine on the rolling body, and reflexing to photoinduction sensor reflective light intensity weakly heterogeneous just can not be very big, and the photoinduction sensor will produce another kind of signal.
Step S104 determines that according to the photoinduction sensor signal this rolling bearing lacks retainer, reaches a conclusion, and detects and finishes;
Step S105 determines that according to the photoinduction sensor signal this rolling bearing retainer does not lack, and detects and finishes.
The description of this example is to use looks for the photoinduction sensor a little recognized in the face device to detect in the greasing gland machine, those skilled in the art can understand, use the photoinduction sensor on other equipment or the photoinduction sensor of other types also can realize the method whether above-mentioned detection rolling bearing retainer lacks, improved the automaticity that rolling bearing detects.
In actual production, the rolling body of the rolling bearing of retainer disappearance may accumulate in a section of rolling bearing roll channel, as shown in Figure 2, when rolling bearing retainer lacks, because rolling bearing tilts, all rolling bodys 1 just may contact when being arranged on the roll channel between the rolling bearing Internal and external cycle in proper order, and on annular roll channel, the radian measure beta between two ends rolling body 1 rolling centerline will be smaller.Detect in this case, when the relative rolling bearing anglec of rotation of light beam hour, the light beam irradiates scope may just in time be to be positioned at rolling body neutral gear place, just light beam irradiates is in the α scope, the reflective light intensity weakly heterogeneous that reflexes to the photoinduction sensor also can be very little, the photoinduction sensor will produce the signal that retainer exists, and gets the wrong sow by the ear, and produces erroneous judgement; If make the relative rolling bearing anglec of rotation of light beam very big, when spending, can increase detection time again such as 360, reduce detection efficiency.
Embodiment two just provides a kind of can avoiding to judge by accident in these cases, can guarantee the method whether the detection rolling bearing retainer of higher detection efficiency lacks again.In this embodiment, light beam has been carried out accurate control with respect to the angle of rolling bearing rotation, promptly in the foregoing description step S102, the anglec of rotation that makes described photoinduction sensor is α; Wherein, described α is not less than 360 °-β, and described β is that the whole rolling bodys on the rolling bearing contact when being arranged on the roll channel between the rolling bearing Internal and external cycle in proper order, on annular roll channel, and the radian between the rolling body rolling centerline of two ends.When the photoinduction sensor is α with respect to the rolling bearing anglec of rotation, even when retainer lacks, whole rolling bodys on the rolling bearing contact in proper order and are arranged on the roll channel between the rolling bearing Internal and external cycle, the light beam of photoinduction sensor just can only not shine in the neutral gear between the rolling body, also just shine on the rolling body, produce correct signal, the erroneous judgement of avoiding.Certainly, those skilled in the art can understand, all rolling bodys contact in proper order and are arranged on the roll channel between the rolling bearing Internal and external cycle, when light beam is slightly less than α with respect to the anglec of rotation of rolling bearing, light beam also can shine the rolling body edge, also can make right judgement when the photoinduction transducer sensitivity is higher, adopting α in this example is in order to strengthen the reliability of testing result.According to the standard of rolling bearing, can determine, when α is not less than the 170 ° of erroneous judgements that just can avoid in these cases.
In actual production process, make rolling bearing should have the retainer one side method relative to be with the photoinduction sensor, in operation before, rolling bearing is carried out respective handling, such as: after the rolling bearing gap is checked, rolling bearing is put into before the cleaning machine, the placement that faces down that makes that rolling body exposes, retainer is simultaneously unified to be placed up so that rolling bearing should have, after cleaning, although the retainer of some rolling bearing may lack because of cleaning, can guarantee have the one side of retainer relative with the photoinduction sensor; Also can be the arbitrary face of rolling bearing to be detected with the light induction pick-up, when the one side of finding to be detected be rolling body expose one side the time, just inferring another side is the one side that retainer is arranged, otherwise, just confirm that it simultaneously is the one side that retainer is arranged that institute is detected.In order further to raise the efficiency, optimized technical scheme is after the rolling bearing gap is checked, before the cleaning, places rolling bearing is unified, so that in greasing gland machine flow process, whether rolling bearing retainer is lacked detect.As shown in Figure 3, the method that whether lacks of the detection rolling bearing retainer that provides of embodiment three has been carried out after greasing exactly.In the method, make rolling bearing should have the retainer one side step S101 relative to comprise before with the photoinduction sensor:
Step S100 one carries out greasing in the face of rolling bearing what the rolling bearing rolling body exposed.
Making rolling bearing should have the retainer one side relative with the photoinduction sensor described in the embodiment one in the step 101, specifically is that rolling bearing is turned over turnback.Greasing will be carried out in the one side that rolling body exposes, therefore, during greasing, the one side that rolling body exposes necessarily with the photoinduction sensor with, therefore, rolling bearing need be turned over turnback.
Certainly, after step S105 determines that this rolling bearing has retainer, a step S106 who rolling bearing is carried out the grease inspection can also be arranged.
Before cleaning, the one side that axis of rolling rolling body can be exposed is unified places up; After the cleaning, rolling bearing will be unified to be sent on the corresponding greasing station of greasing gland machine towards ground, carries out step S100 then, carries out greasing.Other steps are identical with embodiment one, do not repeat them here.
In this example, be the method whether the detection rolling bearing retainer lacks to be arranged in the greasing gland flow process carry out, do not increase equipment so on the one hand, can save the flow process whether the manual detection rolling bearing retainer lacks on the other hand, the automaticity that the rolling bearing that improves is produced has reduced the production cost of rolling bearing.Certainly, in this routine step, also the angle of photoinduction sensor rotation can be defined as α, α is not less than 360 °-β, described β is that the whole rolling bodys on the rolling bearing contact when being arranged on the roll channel between the rolling bearing Internal and external cycle in proper order, on annular roll channel, the radian between the rolling body rolling centerline of two ends.
The detection of rolling bearing retainer is carried out in the greasing gland flow process in the last example, has saved production run.But, in the said process method, after to the rolling bearing greasing, more whether rolling bearing retainer is lacked and detects, when detecting the rolling bearing retainer disappearance, rolling bearing need be ressembled, but rolling bearing passes through greasing, thereby caused the wasting of resources easily.For fear of the waste of railway grease, embodiment four provides a kind of detection afterwards in the method to the rolling bearing greasing, and in this method, preceding step is identical with embodiment one, and difference is, after step S105, also comprises:
Step S201 overturns rolling bearing.Testing result is that retainer exists, and therefore rolling bearing need be overturn, and just can carry out greasing after the upset.
Step S202 one carries out greasing in the face of rolling bearing what the rolling bearing rolling body exposed.After the upset, have one of retainer to face down, the one side that the rolling bearing rolling body exposes can be carried out greasing just up.
Step S203, the grease inspection, flow process finishes.Can pack, load and transport or put in storage rolling bearing then.
In this example, carry out the detection whether rolling bearing retainer lacks earlier, the rolling bearing for rolling bearing retainer exists carries out greasing again; When determining that after detection rolling bearing keeps disappearance, just needn't carry out greasing, should return the production assemble flow, assemble rolling bearing; After detection, when determining that rolling bearing retainer exists, just be necessary rolling bearing is carried out greasing.Certainly, among this routine step S102, also the angle of photoinduction sensor rotation accurately can be limited, to avoid error in judgement.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
