Abstract
A serial combined thrust bearing with shaft ring seat ring and internal and external ring separately integrated belongs to the bearing field in mechanical engineering. The utility model makes a prior shaft ring and a prior internal ring into an integral shaft ring, and also makes a prior seat ring and a prior external ring into an integral seat ring structure which consists of a plurality of serial non-standard cylindrical roller thrust bearings. The non-standard cylindrical roller thrust bearings comprises shaft rings, holder components and seat rings, shaft rings and seat rings with shorter axial length, which are orderly arranged on the two ends of the serial combined thrust bearing. Because of increase of component rigidity, the utility model is not easy to deform under mechanical processing and heat treatment, furthermore saves an exclusive clamping apparatus of tool set during processing. Concerning bearings with shorter external diameter, the small number of components enables a great reduce of processing quantity. The utility model has simple structure, easy manufacture, reduced defective index and consequent greatly reduced manufacture cost.
Description
Technical field
The utility model relates to a kind of combined thrust-bearing, the tandem compound type thrust-bearing that particularly a kind of blowout patche seat ring and inside and outside spacer ring are unified respectively belongs to mechanical engineering middle (center) bearing field.
Background technique
Tandem compound type cylindrical roller thrust bearing is exclusively used in important chemical industry, light indusqtry machinery is equipped a parallel flat screw extruder, is the novel thrust bearing group that a kind of radial dimension is little, weight bearing power is big.During parallel double-screw extruder work, produce very big axial force on the screw rod of rotation, because two screw axis spacings that are arranged in parallel are very little, limited the size of thrust-bearing, therefore have to share and bear axial load with the thrust-bearing of one group of several less external diameter, the thrust bearing group of this kind high load is by several same non-standard cylindrical roller thrust bearing and cylindrical cone spacer therebetween, the outer ring spacer series connection constitutes, cone spacer is between the adjacent blowout patche of thrust bearing group, outer ring spacer is between the adjacent seat ring of thrust bearing group, each cylindrical roller thrust bearing should be able to be shared line shaft more equably to load, this is the big key of thrust bearing group weight bearing power, the life-span of reducing whole bearing pack in order to avoid wherein indivedual excessive life-span of bearing load is short.The method that realizes this requirement at present is with in each, the wall thickness design of outer ring spacer is made unequal, thereby transmit and the shunting axial force by it, on putting in order, the wall thickness of each outer ring spacer is from being thinned to thick increasing progressively, otherwise the wall thickness of each cone spacer successively decreases, in each, outer ring spacer or only be the thick slightly and uniform thickness of support zone at two ends own, putting in order the preceding, the wall thickness of several outer ring spacers generally is less than one millimeter, no matter its model and outside dimension are much, Design Theory is like this substantially, find by literature search, China Patent No. is: 00258777, name is called: tape spool type tandem cylindrical roller thrust bearing, this patented technology readme is: a kind of tape spool type tandem cylindrical roller thrust bearing, and it is by the single-stage cylindrical roller thrust bearing, outer ring spacer, cone spacer and axle are formed, between the single-stage cylindrical roller thrust bearing in, the outer ring spacer connect in series is on axle, and, form tape spool type tandem cylindrical roller thrust bearing unit assembly with spring collar locking.The utility model is a non-removable unit assembly, though under the condition of limited bearing radial dimension, utilize do not wait the wall thickness variable cross section in, outer ring spacer transmits and the shunting axial force, tandem cylindrical roller thrust bearing unit assembly weight bearing power is multiplied, but when the thin-walled of its outer ring spacer of processing, machine cut processing is difficult for, need with special-purpose frock clamping, and still easy deformation is excessive after the heat treatment, bring difficulty for follow-up grinding process, the processing reject rate is very high, particularly for the less tandem compound type thrust-bearing of external diameter, the thinner easier machining deformation of outer ring spacer wall thickness, and because the more required precision of bearing pack part is very high again, corresponding machining amount is therefore very big, and manufacture cost is also just high, to such an extent as to above-mentioned The Application of Technology is subjected to very big restriction.
Summary of the invention
The utility model is at the deficiencies in the prior art and defective, the tandem compound type thrust-bearing that provides a kind of blowout patche seat ring and inside and outside spacer ring to unify respectively, overcome the processing restriction, blowout patche of the prior art and cone spacer are designed to the blowout patche () of one, are seat ring () structure of one with seat ring of the prior art and outer ring spacer, greatly make things convenient for its processing after changing the design of part situation.The utility model is made of several off-gauge cylindrical roller thrust bearing series connection, off-gauge cylindrical roller thrust bearing comprises: blowout patche () and (two), retainer assembly, seat ring () and (two), except blowout patche (two) that is arranged in primary importance in order and the seat ring (two) that is arranged in the rearmost position, all the other whole blowout patches (one) and seat ring () length all equate.The cone spacer and the outer ring spacer of independent setting have been cancelled in the utility model structure, it is not changed substantially with blowout patche and the seat ring total boundary dimension in back that is connected as a single entity respectively, therefore the blowout patche of new structure and seat ring substitute cone spacer and the outer ring spacer in original structure, still play a part to transmit and the shunting axial force.
After the utility model blowout patche and cone spacer, seat ring and outer ring spacer were integrated, original thin-walled parts rigidity greatly increased, and metal machine cut processing and heat treatment are not yielding, also can therefore omit the special tooling anchor clamps; And for the less the utility model of external diameter, axle, the seat ring part is very little, and metal machine cut adds and do not need to remove a large amount of metals man-hour and cause time-consuming taking a lot of work and the waste of material; Originally need the part of machining, fine abrasive plane nearly to reduce half because number of spare parts reduces to make, so machining amount significantly reduces, the utility model is simple in structure, easy to manufacture, and reject rate descends, and therefore cost of production reduces significantly.

Embodiment
As shown in Figure 1, blowout patche, seat ring, cone spacer, outer ring spacer in the prior art are designed to blowout patche and cone spacer is that blowout patche 1, seat ring and the outer ring spacer of one is seat ring 3 structures of one to the utility model.
The utility model is made of several off-gauge cylindrical roller thrust bearing series connection, off-gauge cylindrical roller thrust bearing comprises: former blowout patche and cone spacer are designed to the blowout patche 1 of one, are seat ring 3 structures of one with former seat ring and outer ring spacer, off-gauge cylindrical roller thrust bearing also comprises: blowout patche 4, retainer assembly 2, seat ring 5, except blowout patche 4 that is arranged in primary importance in order and the seat ring 5 that is arranged in the rearmost position, all the other whole blowout patches 1 and seat ring 3 equal in length.
The cone spacer and the outer ring spacer of independent setting have been cancelled in the utility model structure, it is not changed substantially with blowout patche and the seat ring total boundary dimension in back that is connected as a single entity respectively, therefore the blowout patche 1 of new structure and 4 and seat ring 3 and 5 cone spacer and the outer ring spacers that substitute in original structures still plays a part to transmit and the shunting axial force.
