Abstract
A kind of lubricating structure of marine low speed diesel engine main bearing, it comprises oil pipe and flange, described oil pipe is through the support of described marine low speed diesel engine and frame and be fixed in this frame, one end connects the top of the main bearing cap of described marine low speed diesel engine and carries lubricant oil from main bearing described in upper direction, the other end is connected in the oil inlet on described support and introduces lubricant oil, described flange be arranged at respectively described oil pipe and described main bearing cap, with described frame and the joint with described oil inlet.The utility model improves the sealing of lubrication system, improves the reliability of main bearing seat and reduces the manufacture cost of main bearing seat.
Description
Technical field
The utility model relates to the lubrication of diesel engine, is specifically related to a kind of lubricating structure of marine low speed diesel engine main bearing, belongs to Marine Diesels field.
Background technique
Main bearing oil pipe is specially for marine low speed diesel engine main bearing provides the device of lubricant oil, but due to the restriction of low-speed diesel engine inner space, oil pipe is just arrived above main bearing by the flank hole at main bearing seat to lubricate main bearing, the this of oil pipe arranges the reliability that trend reduces main bearing, add the manufacture cost of main bearing seat, also easily reveal at the oil pipe joint lubricating oil of diesel engines simultaneously, cause the loss of oil flow and pressure.
Model utility content
Technical problem to be solved in the utility model is, overcome the deficiency that existing ship diesel engine main bearing lubricating structure exists, a kind of lubricating structure of marine low speed diesel engine main bearing is provided, by increasing special flange and by the structure of main bearing cap to main bearing supply lubricant oil, reaching the reliability of raising main bearing seat, reduce the manufacture cost of main bearing seat and improve the effect of lubrication system sealing.
The utility model solves the technological scheme that its technical problem adopts:
A kind of lubricating structure of marine low speed diesel engine main bearing, it comprises oil pipe and flange, described oil pipe is through the support of described marine low speed diesel engine and frame and be fixed in this frame, one end connects the top of the main bearing cap of described marine low speed diesel engine and carries lubricant oil from main bearing described in upper direction, the other end is connected in the oil inlet on described support and introduces lubricant oil, described flange be arranged at respectively described oil pipe and described main bearing cap, with described frame and the joint with described oil inlet.
Further, described oil pipe is close to the wallboard of described frame.
Further, described flange is provided with circular groove, is provided with the O RunddichtringO for sealing in this circular groove.
Compared with prior art, the beneficial effects of the utility model are:
(1) main bearing oil pipe is directly connected to main bearing cap top through support and frame, above main bearing, main bearing is lubricated, and the flank hole noting be used in main bearing seat makes oil pipe pass through, thus improve the reliability of main bearing seat, reduce the manufacture cost of main bearing seat simultaneously.
(2) flange that with the joint of oil pipe all have employed with O RunddichtringO all in diesel engines, this compares with common flange connection, and sealing is more reliable.
Accompanying drawing explanation
Fig. 1 is schematic perspective view of the present utility model.
Fig. 2 is plan view of the present utility model.
Fig. 3 is the schematic diagram of flange.
Embodiment
Be described in further detail below in conjunction with the lubricating structure of the drawings and specific embodiments to marine low speed diesel engine main bearing described in the utility model, but protection domain of the present utility model should do not limited with this.
Incorporated by reference to consulting Fig. 1 and Fig. 2, the lubricating structure of diagram marine low speed diesel engine main bearing comprises oil pipe 1 and flange 4.
Described oil pipe 1 passes support 2 and the frame 3 of described marine low speed diesel engine, and this oil pipe 1 is weldingly fixed in this frame 3, and is close to the wallboard of described frame 3, to reduce the vibration of this oil pipe 1; Described oil pipe 1 one end connects the top of the main bearing cap 6 of described marine low speed diesel engine and from main bearing conveying lubricant oil described in upper direction, the other end is connected in the oil inlet 7 on described support 2 and introduces lubricant oil.Described oil pipe 1 does not adopt conventional construction, is not to arrive above main bearing at the flank hole of main bearing seat 5 to lubricate, thus reduces the manufacture cost of main bearing seat 5, improves the reliability of main bearing seat 5.
Described flange 4 is arranged at described oil pipe 1 and the joint of described main bearing cap 6, the joint of described oil pipe 1 with described frame 3 and the joint of described oil pipe 1 and described oil inlet 7 respectively, refer to Fig. 3, described flange 4 is provided with circular groove, O RunddichtringO 8 for sealing is installed in this circular groove, thus ensure that the sealing that pipeline is good.
Claims (3)
1. the lubricating structure of a marine low speed diesel engine main bearing, it is characterized in that: described lubricating structure comprises oil pipe and flange, described oil pipe is through the support of described marine low speed diesel engine and frame and be fixed in this frame, one end connects the top of the main bearing cap of described marine low speed diesel engine and carries lubricant oil from main bearing described in upper direction, the other end is connected in the oil inlet on described support and introduces lubricant oil, described flange be arranged at respectively described oil pipe and described main bearing cap, with described frame and the joint with described oil inlet.
