A framework oil seal is arranged between the adjusting sleeve and the bearing seat; an O-shaped ring is arranged between the bearing seat and the end cover; an oil cup is arranged on the end cover. The sealed lubricating device is arranged at the two shaft ends of the stern roller, and the lubricating manner is changed, so that the structure of the stern roller can be made into an integrated welding member. At the same time, the sealing property of the roller body is ensured, and the service life of the roller is greatly prolonged; besides, the two short shafts are only required to be processed during processing and manufacturing, the processing difficulty is reduced, the material is saved, the cost is reduced, and the competitive force of the product is improved.
Description
Technical field
The utility model relates to boats and ships, particularly relates to the airtight lubricating fitting on ship stern cylinder.
Background technique
The lubricating fitting using on large ship stern cylinder, traditional structure is generally arranged on inner barrel, when not only installation, cannot see intuitively inner case, and also cannot know the actual conditions in cylinder while safeguarding, once go wrong, dismounting will be a unusual problem for trouble, and by the part pull-out meeting installing by part surface plucking.Difficulty is installed, and processing request is high, and maintaining inconvenience, and the easy generation of long duration dead phenomenon of becoming rusty have had a strong impact on the construction operation progress of boats and ships.
Summary of the invention
The purpose of this utility model will provide a kind of boats and ships exactly
airtight lubricating fitting on stern cylinder, its energy gram
take the above defect that conventional construction exists.the purpose of this utility model is achieved in that boats and ships
airtight lubricating fitting on stern cylinder, comprisesbearing support, selfaligning roller bearing, minor axis,
it is characterized in that:the two ends of roller respectively arrange a minor axis, between minor axis and bearing support, are provided with selfaligning roller bearing, and one end of selfaligning roller bearing is provided with adjusting sleeve, and the other end of selfaligning roller bearing is provided with end cap, and are connected with bearing support through end cap by bolt.
Between described adjusting sleeve and bearing support, be provided with outside framework oil seal;
Between described bearing support and end cap, be provided with O type circle;
On described end cap, be provided with lubricating cup.
The utility model is set to seal lubrication device two axle heads of stern cylinder, and improves lubricating system, and the structure of stern cylinder just can be made an integral solder part like this, has also guaranteed the seal of cylindrical shell simultaneously, has greatly increased the working life of cylinder; And, in the time of manufacturing, only need to process two minor axises, reduce difficulty of processing, save material, reduce cost, strengthen the competitive ability of product.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
1, outside framework oil seal, 2, selfaligning roller bearing, 3, bearing support, 4, bolt, 5, O type circle,
6, end cap, 7, minor axis, 8, lubricating cup, 9, adjusting sleeve.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail;
Boats and ships
airtight lubricating fitting on stern cylinder, comprisesbearing support 3, selfaligning roller bearing 2, minor axis 7,
it is characterized in that:the two ends of roller respectively arrange a minor axis 7, between minor axis 7 and bearing support 3, are provided with selfaligning roller bearing 2; One end of selfaligning roller bearing 2 is provided with adjusting sleeve 9, and the other end of selfaligning roller bearing 2 is provided with end cap 6, and is connected with bearing support 3 through end cap 6 by bolt 4.
Between described adjusting sleeve 9 and bearing support 3, be provided with outside framework oil seal 1;
Between described bearing support 3 and end cap 6, be provided with O type circle 5;
On described end cap 6, be provided with lubricating cup 8.
When concrete enforcement, design of the present utility model is that roller tube is rotated together with axle, and object will be improved lubricating fitting exactly, makes it simplification, practicality, thereby reach, the structural configuration of stern cylinder is more optimized, and has solved the deficiency that old-fashioned cylinder exists.
A. selfaligning roller bearing 2 the diaxon concentric problem that can solve cylinder is set, in general, the processing of stern cylinder two ends minor axis is carried out respectively, during due to second minor axis of processing, cylinder need to be reversed end for end, this will cause the machining center of second minor axis and the machining center of first minor axis not on same straight line, although add the concentricity that can adopt man-hour dial gauge to adjust axle, also have certain error.Adopt selfaligning roller bearing can utilize the self-regulation of bearing to eliminate this impact, meanwhile, arranging of selfaligning roller bearing can reduce processing request, thereby simplifies technique, cost-saving.
B. adjusting sleeve 4 arranges for the axial motion problem and processing, the alignment error that solve roller; processing by adjusting sleeve length regulates; on the basis of withstanding axial motion; solved the problem of installation deviation in the mode of now joining; meanwhile, this adjusting sleeve has encased the exposed part of axle, because the material of axle itself is corrosion-resistant not; and kinetic friction place paint can not guarantee anticorrosion, therefore adjusting sleeve adopts 316L stainless steel also to play the effect of protection axle.
C. the main object that arranges of end cap 5 is for sealing, and meanwhile, the end cap of reassembling type is also beneficial to maintenance, or else needs the dismounting of stern cylinder bearing to extract out, and only need open a lid just can see internal fault clearly.
D. lubricating cup 7 be provided for oiling and topping-up, traditional structure is generally a lubricating cup, is set to two lubricating cups here, a lubricating cup is set suitable for reading more, fills up lubricating fitting for exhaust to guarantee oil.Meanwhile, this lubricating cup also plays a part oil filler for subsequent use and is blocked by foreign material to prevent another oil filler.
E. the object that outside framework oil seal 8 arranges is in order to solve kinetic friction sealing problem, and this oil sealing is installed more convenient, and performance is also reliable, adopts more extensively, also can increase an outside framework oil seal depending on concrete condition, and double sealing structure is more firm.
The object that F.O type circle 9 arranges is the sealing problem in order to ensure end caps, although end cap and bearing support end face are all finished, but steel material face and face laminating are difficult to sealing, therefore, an O type circle need to be set and block possible leakage, sealing circle is oil resistant anti-corrosive rubber material, durable in use.
Running principle is exactly: axle, roller, the as a whole structure of adjusting sleeve, on selfaligning roller bearing, rotate, between axle and bearing support, adopt the outside framework oil seal of motive sealing to prevent from revealing, stern cylinder two ends arrange end cap, and it is static seal that O type circle is set between end cap and bearing support.
Improve traditional lubricating system, simplify technique, the difficulty of reduce processing, installing, safeguarding.Device technique after entering is more simple, installs more convenient.
