Abstract
A full-sealed type rotation connector component is used for roller ends of acid-washing phosphorus breaking working rollers. A bearing which is a combination of a deep groove ball bearing and a thrust ball bearing is arranged between a shaft and an outer sleeve, an end cover is screwed on the end portion of the outer sleeve, a sealing system is arranged between the end cover and the shaft, and the outer sleeve is connected with a roll shaft through a screw. A first sealing ring is installed between the deep groove ball bearing and the shaft, a separation sleeve is installed between the end portion of the thrust ball bearing and the outer sleeve, and a second sealing ring is arranged on the separation sleeve. The full-sealed type rotation connector component is in clearance fit with the working rollers, can be slightly taken out in coping and is convenient to replace. The full-sealed type rotation connector component adopts assembly of the deep groove ball bearing and the thrust ball bearing, thereby being large in axial bearing capability. The full-sealed type rotation connector component can keep that a rotation connector and a roller run stably and reliably, the independent full-sealed type structure avoids invalidation possibly caused by coping, and the full-sealed type rotation connector component is stable in performance and long in service life.
Description
Technical field
The utility model relates to technical field of bearings, especially for the nonstandard all-sealed swivel joint constituent element of the broken phosphorus work roll roller end of each serial pickling.
Background technique
Existing rotary joint structure is made up of parts such as a pair of angular contact bearing that disposes back-to-back, reinforced seal, overcoat, top covers.This swivel joint has compact structure, advantage that bearing capacity is high, but installation precision is had relatively high expectations, and particularly work roll is when reconditioning, and outside its bearing was exposed to, foreign matters such as grinding fluid were prone to get into bearing, when re-using, cause swivel joint to lose efficacy in advance.
Summary of the invention
For overcoming the deficiency of existing technology; The goal of the invention of the utility model is to provide a kind of all-sealed swivel joint constituent element; When the roller reconditioning, can integral installation dismantle, solve the problem that causes swivel joint generation early failue because of the work roll reconditioning, reduce the user cost of roller.
For realizing above-mentioned purpose, between axle of the utility model and the overcoat bearing is housed, bearing is the combination of deep groove ball bearing and thrust ball bearing, and end cap is spun on the end of overcoat, is provided with sealing system between end cap and the axle, and overcoat is connected through screw with roll shaft;
Between deep groove ball bearing and the axle seal ring one is housed, between the end of thrust ball bearing and the overcoat spacer is housed, spacer is provided with seal ring two.
The utility model compared with prior art has the following advantages:
1, swivel joint and work roll Spielpassung can easily be taken out during reconditioning, and it is convenient to change;
2, adopt the assembling of deep groove ball bearing and thrust ball bearing, axial carrying capacity is big, and can keep swivel joint and roller to stablize can
By operation, the inefficacy factor that possibly cause when independently all-sealed structure has been avoided reconditioning, stable performance, the life-span is high.
Description of drawings
Fig. 1 is the structural drawing of the utility model.
Embodiment
Shown in accompanying drawing, between axle 1 and the overcoat 6 bearing is housed, bearing is the combination of two cover deep groove ball bearings 4 and a cover thrust ball bearing 5; End cap 2 is spun on the end of overcoat 6; Be provided with sealing system 3 between end cap 2 and the axle 1, overcoat 6 is connected through screw 8 with roll shaft 9, between deep groove ball bearing 4 and the axle 1 seal ring 1 is housed; Between the end of thrust ball bearing 5 and the overcoat 6 spacer 7 is housed, spacer 7 is provided with seal ring 2 10.
The endoporus of the overcoat 6 of the utility model and roll shaft 9 are Spielpassung, through screw 8 fastening and roll shaft 9 quick releases; The utility model has adopted 2 cover deep groove ball bearings 4 to overlap thrust ball bearing 5 with one, and axial maximum dynamic load is 55.6KN, compares with existing swivel joint and has improved three times, and mean lifetime is 27 times of original structure in theory; Filled enough brand-name greases in the joint, and sealing is reliable, can be non-maintaining in the spreadable life.
