Description
Technical field
A kind of planet rolling bearing system that is used for circular knitting machine supporting deep bid and the rotation of deep bid gear.
Background technology
One, its structure of the known rolling bearing of people is made up of the inner ring of rolling bearing, outer ring, one group of steel ball and ball retainer.Its occupation mode: be with the inner ring of rolling bearing and the axle of machine components, design screw thread by interference fit or on axle, be fastened on nut on the axle of machine components; With the outer ring of rolling bearing and the hole of another machine components, design screwed hole by interference fit or in the outside in hole, and design a kind of end cap of special compression axis bearing outer-ring, with screw and end cap bearing outer ring is fastened in the hole of machine components.When the axle of machine components was fixed, at this moment the hole of machine components was around the running of machine components axle, and when the machine components hole was fixed, at this moment the axle of machine components just turned round around the axle center in the hole of machine components.
Two, the known circular knitting machine of people is in the process of running, and deep bid is equivalent to the axle of machine components, and the deep bid gear is equivalent to the hole of machine components.It is motionless that deep bid is fixed on the frame, and the deep bid gear turns round around the deep bid axle center.
Three, one of critical piece of installation knitting machine syringe on the deep bid gear of the known circular knitting machine of people, circular knitting machine is the higher machinery of a kind of required precision.Especially syringe end face run-out requirement in the running is below 0.05mm, and circular runout requires below 0.05mm equally.Only reach above requirement, circular knitting machine just can knit out high-quality smooth smooth knitted fabric.
Four, the rotation of current circular knitting machine supporting deep bid and deep bid gear.Used bearing mainly contains two kinds; A kind of is steel wire runway rolling bearing; As Figure 22, shown in Figure 23.A kind of is the wear plate sliding bearing; As Figure 29, shown in Figure 30.As follows with regard to these two kinds of existing case studies of bearing below:
Five, according to structure and the occupation mode and the required precision in the running of circular knitting machine syringe of rolling bearing as described above: we at first analyze the structure and the occupation mode of steel wire runway rolling bearing, with regard to very clearly it has following problem as can be seen: shown in Figure 22ly be the front view of steel wire runway rolling bearing general assembly drawing, shown in Figure 23 is the vertical view of steel wire runway rolling bearing general assembly drawing.Figure 24 is the front view A partial enlarged drawing of Figure 22 steel wire runway rolling bearing general assembly drawing: 24-a; Deep bid gear, 24-b; Deep bid, 24-c; Steel wire runway, 24-d; Steel ball, 24-e; Steel ball plastic cage protecting band, 22-f; Deep bid gear center hole and deep bid central shaft cooperation place.Figure 25 is the front view B partial enlarged drawing of Figure 22 steel wire runway rolling bearing general assembly drawing: 25-a; Steel wire runway and deep bid gear installation position, 25-b; Steel wire runway and deep bid installation position.Because the deep bid of circular knitting machine and the diameter of deep bid gear are general bigger, if use conventional large diameter rolling bearing to support the running of deep bid and deep bid gear.Manufacturing will be very difficult, and manufacturing cost also can be very expensive.So people adopt 4 steel wires, grind an arc groove identical on the every steel wire with steel ball size.Wherein there are two steel wires to be equivalent to the inner ring of rolling bearing; The two other steel wire is equivalent to the outer ring of rolling bearing.The inside and outside circle of conventional rolling bearing is whole annulus, and mill has the very smooth arc groove identical with steel ball size on the annulus.And the inside and outside circle of steel wire runway rolling bearing is to form with a straight steel wire bending, so it is not a complete annulus, has breach in the joint.Because consider the reason of expanding with heat and contract with cold of object, this breach must leave the gap of 0.5mm-1mm.From 25-a shown in Figure 25; For installation position, the 25-b of steel wire runway and deep bid gear is the installation position of steel wire runway and deep bid.So because the steel wire diameter of steel wire runway have only 4mm. we see be equivalent to the inside and outside circle of rolling bearing 4 steel wire runways can not with deep bid gear, deep bid steel wire runway installation position interference fit, also can't design any device 4 steel wire runways are fastened on deep bid, the deep bid gear.So the steel wire runway can't be fixed on the installation position of deep bid and deep bid gear.Therefore when the deep bid gear turns round around the deep bid axle center, because the steel wire runway is not fixed on the installation position of deep bid and deep bid gear, and every all leaving certain gaps uncovered by the economic plan of steel wire runway, steel ball will inevitably drive the steel wire runway when rolling in the runway the inside and produce the sliding friction campaign in the installation position of deep bid and deep bid gear.The material of the known deep bid gear of people is that the material of spheroidal graphite cast-iron, deep bid is a casting pig.Their hardness is all low than steel wire runway.Therefore be easy to installation position wearing and tearing with steel wire runway and deep bid gear and deep bid.From the condition diagram after Figure 26 steel wire runway and the installation position wearing and tearing: we can see 26-a; Situation, the 26-b of steel wire runway and the wearing and tearing of deep bid gear installation position; The situation of steel wire runway and the wearing and tearing of deep bid installation position.26-c; The arc groove of steel wire runway contacts with steel ball formation point, 26-d; The arc groove and the steel ball of steel wire runway are contactless.Therefore wearing and tearing cause that steel ball can not normally roll in steel wire runway arc groove, have caused the working environment of steel ball to worsen.Thereby the precision of circular knitting machine is reduced, and the running noise of circular knitting machine increases, and causes circular knitting machine to run well at last.And this wearing and tearing have directly caused scrapping of deep bid gear and deep bid.Wear and tear because deep bid gear and deep bid are installed the position of steel wire runway,, also have no idea to recover the precision of circular knitting machine so be exactly more to renew the steel wire runway.In order to prolong the service life of circular knitting machine, improve the anti-wear performance of circular knitting machine.A lot of circular knitting machine manufacturers can only try every possible means with the material of the anti-wear performance that improves deep bid and deep bid gear.Thereby improved the cost of circular knitting machine widely, but do not tackled the problem at its root.(2) from Figure 24-f; Deep bid gear center hole and deep bid central shaft cooperation place: we can see that the deep bid gear center hole cooperates to belong to the radial clearance of deep bid central shaft and be slidingly matched.Because directly beating, the syringe of circular knitting machine requires in 0.05mm, so the centre bore of deep bid gear and deep bid central shaft cooperation place only allow very little gap.When the gap surpassed 0.10mm, this did not meet with regard to the precision that makes circular knitting machine and has weaved production requirement, and the quality of knitted fabric will greatly reduce.The main rotation gear of the deep bid gear of the known circular knitting machine of people and its engagement is the pair of straight gear, and the known intermeshing pair of straight gear of people can produce mutually exclusive radial thrust each other.Because the hole of deep bid gear and the central shaft of deep bid gear are directly frictions, so be easy to cause wearing and tearing.How long have more than is needed, will make the radial fit gap of deep bid gear and deep bid central shaft circular knitting machine can not be run well above 0.10mm..(3) on circular knitting machine, use the steel wire runway in addition, steel wire runway deep bid gear position and deep bid spot size are installed are reached very high precision.When steel wire runway deep bid gear position and deep bid position diameter being installed very little error is arranged, steel wire runway and steel ball cooperate in the condition diagram as can be seen: 27-a from Figure 27; Deep bid gear steel wire runway installation position is greater than intended diameter, 27-b; Deep bid steel wire runway installation position forms less than intended diameter, 27-c steel wire runway arc groove and steel ball that point contacts, 27-d; Contactless, the 27-e of steel wire runway arc groove and steel ball; Steel wire runway arc groove contacts well with steel ball.Hence one can see that: arc groove that should have 4 steel wire runways all has should be with the steel ball no-float, has only two cooperations passable now.From Figure 28: when steel wire runway deep bid gear position and deep bid position groove width size being installed when error is arranged, steel wire runway arc groove and steel ball cooperate in the condition diagram as can be seen: 28-a steel wire runway installation position is greater than design groove width size, 28-b; Steel wire runway installation position is less than design groove width size, 28-c; Steel wire runway arc groove contacts with steel ball formation point, 28-d; Steel wire runway arc groove is contactless with steel ball, four steel wire runways all cooperate bad with steel ball.If not enough from the installation position precision of the above runway of steel wire as can be seen, the cooperation of the arc groove of steel ball and steel wire runway is just misfitted so, and the steel wire runway just is easy to wearing and tearing, thereby causes the precision of circular knitting machine to reduce.Directly influencing the quality of knitted fabric, cause circular knitting machine to run well at last. the problem that above analysis is shown, people are known in circular knitting machine use and the manufacture process and exist in a large number.
Five, about wear plate sliding bearing: Figure 29 be the front view of wear plate sliding bearing general assembly drawing, Figure 30 is the vertical view of wear plate slip general assembly drawing bearing, and Figure 31 is the front view F partial enlarged drawing of Figure 29 wear plate sliding bearing general assembly drawing: 31-a; Deep bid gear, 31-b; Deep bid, 31-c; Wear plate steel part matrix, 31-d; Wear plate, 31-e; Wear plate fixed screw, 31-f; Deep bid gear face and cooperation place, wear plate plane, 31-g; Deep bid gear center hole and deep bid central shaft cooperation place.The structure of root a tree name sliding bearing and occupation mode and the on-stream required precision of circular knitting machine syringe: we analyze its existing problem: the known sliding bearing frictional resistance of (1) people is big more a lot of than rolling bearing, so the motor power (output) that it was equipped with is bigger than the power of electric motor of using rolling bearing.And start with the regional this circular knitting machine of cold is very difficult in the winter time.This circular knitting machine also is difficult to run up simultaneously.(2) the deep bid gear center hole is the same with the circular knitting machine of deep bid central shaft cooperation place and use steel wire runway.All be to belong to be slidingly matched, so the problem that produces is the same.Here just need not give unnecessary details.
Summary of the invention
The present invention is a kind of planet rolling bearing system that is used for circular knitting machine supporting deep bid and the rotation of deep bid gear.It is characterized in that adopting the rolling bearing of two groups of routines, be installed on the deep bid as planet is uniform.One group of end face that is used to support the deep bid gear, one group of centre bore that is used to support the deep bid gear.According to the diameter of circular knitting machine, design every group of rolling bearing by the rolling bearing of three routines or more than three conventional rolling bearing form.This routine every group of rolling bearing by six routines is formed.Circular knitting machine adopts planet rolling bearing system to compare following obvious superiority energy with original steel wire runway rolling bearing, wearing piece sliding bearing:
One, because after adopting planet rolling bearing system, the end face of deep bid gear, the centre bore of deep bid gear all are to be supported by rolling bearing during the circular knitting machine running, motion between them is the rolling friction campaign, the frictional resistance that is produced is very little, so get into smooth can be more flexible for circular knitting machine.
Two, Chang Gui bearing is the product of standardization, seriation, and they are by the bearing manufacturer production of specialty.Required precision when so precision can satisfy the circular knitting machine running fully.
Three, behind the employing planet rolling bearing system, the centre bore of the end face of deep bid gear, deep bid gear all is that deep bid gear operation position and deep bid are in contactless state, so deep bid can not produce wearing and tearing by the rolling bearing supporting during circular knitting machine running.Therefore the material wear-resistant performance to deep bid does not just have very high requirement, so aspect material, can reduce the cost of circular knitting machine.
Four, use steel wire runway rolling bearing, the steel wire runway installation position requirement on machining accuracy of the deep bid gear of circular knitting machine and deep bid is very high.A lot of circular knitting machine manufacturers all will adopt NC vertical lathe to process, greatly the production cost of Zeng Jiaing in order to guarantee required precision.After adopting planet rolling bearing system, the running position requirement on machining accuracy of circular knitting machine deep bid gear, deep bid is so not high, and general vertical lathe can be competent at fully, has greatly reduced the production cost of circular knitting machine.
Five, behind the employing planet rolling bearing system, the end face of deep bid gear, the centre bore of deep bid gear all are to be supported by rolling bearing during the circular knitting machine running, motion between them is the rolling friction campaign, the frictional resistance that is produced is very little, deep bid gear and deep bid are in contactless state, so deep bid can not produce wearing and tearing.So just greatly improved the service life of circular knitting machine.
Six, easy to maintenance: after adopting planet rolling bearing system, we know end face and the centre bore that has only the deep bid gear, with the rolling bearing of routine wearing and tearing are arranged, after through long-time running wearing and tearing, if rolling bearing; The deep bid accuracy of gear does not reach the circular knitting machine running requirements, only needs to change conventional rolling bearing, and end face and centre bore reconditioning on grinding machine of deep bid gear just can have been recovered the required precision of circular knitting machine once fully.
Seven, adopt planet rolling bearing system, can repair fully because of circular knitting machine deep bid gear and the wearing and tearing of deep bid steel wire runway installation position, and the circular knitting machine of scrapping.Also can repair the wear plate sliding bearing fully, the circular knitting machine of scrapping because of the centre bore of deep bid gear and the wearing and tearing of deep bid central shaft.
