Description

Technical Field

[0001] The utility model relates to the technical field of diesel engines, in particular to a bushing for a diesel engine. Background Art

[0002] The bushing for diesel engine refers to a ring sleeve that acts as a gasket and is installed between the piston and the connecting rod of the diesel engine. It has good resilience and can bend without deformation, while maintaining toughness and resisting repeated impacts.

[0003] When a traditional bushing is in use, an oil hole is generally opened on the outer wall of the bushing. However, in actual use, when there are too many impurities in the lubricating oil, the impurities in the lubricating oil will cause the inner cavity of the oil hole to be blocked. At this time, the lubricating oil cannot pass through the oil hole smoothly. At this time, the bushing cannot be fully lubricated, resulting in excessive wear of the bushing, which seriously affects the service life of the bushing. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a bushing for a diesel engine, which has the advantages of long service life and good lubrication effect, and solves the problems raised by the above-mentioned background technology.

[0005] The utility model provides the following technical solution: a bushing for a diesel engine, comprising a left bushing, a right bushing being installed on the outer wall of the left bushing, an inner support ring being installed in the inner cavity of the left bushing, an oil-permeable hole being opened on the outer wall of the inner support ring, an oil-through hole being opened on the outer wall of the left bushing, a fixing block being fixedly assembled on the outer wall of the inner support ring, a connecting block being fixedly assembled on the inner wall of the left bushing, a locking block being installed in the inner cavity of the left bushing, a clearing rod being fixedly assembled on the outer wall of the inner support ring, and a crankshaft rod being installed on the inner wall of the inner support ring.

[0006] As a preferred technical solution of the utility model: the shape and size of the outer wall of the left bushing matches the shape and size of the outer wall of the right bushing, and the positions of the oil-permeable holes and the oil-through holes on the outer wall of the inner support ring are staggered.

[0007] As a preferred technical solution of the utility model: the installation position of the dredging rod corresponds to the opening position of the oil through hole, and the outer wall diameter of the dredging rod is smaller than the inner wall diameter of the oil through hole.

[0008] As a preferred technical solution of the utility model: a strong glue is applied to the connection between the outer wall of the fixing block and the outer wall of the connecting block, and the thickness of the strong glue does not exceed 2 mm.

[0009] As a preferred technical solution of the utility model: there are four oil through holes, and the four oil through holes are respectively opened on the outer wall of the left bushing.

[0010] As a preferred technical solution of the utility model: the outer walls of the left bushing and the right bushing are both provided with limiting holes, and the inner wall diameter of the limiting holes is equal to the outer wall diameter of the locking block, and the outer wall of the locking block is installed with a strong magnet.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The diesel engine bushing has an inner support ring arranged in the inner cavity of the left bushing and the right bushing. During the operation of the equipment, once the oil hole is blocked during use, the lubricating oil cannot pass through the oil hole smoothly. At this time, the friction between the inner support ring and the crankshaft rod increases, resulting in the separation between the fixed block and the connecting block. At this time, the inner support ring will rotate on the inner wall of the bushing and clear the oil hole under the action of the clearing rod to avoid blockage of the oil hole, resulting in failure of smooth lubrication, thereby causing serious wear of the bushing.

[0013] 2. The diesel engine bushing has a limiting hole set between the left bushing and the right bushing. When installing the left bushing and the right bushing, it is only necessary to insert the outer wall of the locking block into the limiting hole. At this time, the outer wall of the locking block will be adsorbed between the left bushing and the right bushing to achieve locking of the left bushing and the right bushing. This is very convenient and more conducive to the installation and disassembly of the bushing. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 A bushing for a diesel engine comprises a left bushing 1, a right bushing 2 is installed on the outer wall of the left bushing 1, an inner support ring 3 is installed in the inner cavity of the left bushing 1, an oil hole 4 is opened on the outer wall of the inner support ring 3, an oil hole 5 is opened on the outer wall of the left bushing 1, a fixing block 6 is fixedly assembled on the outer wall of the inner support ring 3, a connecting block 7 is fixedly assembled on the inner wall of the left bushing 1, a locking block 8 is installed in the inner cavity of the left bushing 1, a dredging rod 9 is fixedly assembled on the outer wall of the inner support ring 3, and a crankshaft rod 10 is installed on the inner wall of the inner support ring 3.

[0022] Through the oil hole 5 opened on the outer wall of the left bushing 1, during the normal operation of the equipment, the lubricating oil will enter the inner cavity of the left bushing 1 through the oil hole 5, and pass through the outer wall of the inner support ring 3 through the oil hole 4 opened on the outer wall of the inner support ring 3, so as to lubricate the contact area between the inner support ring 3 and the crankshaft rod 10.

[0023] In a preferred embodiment, the shape and size of the outer wall of the left bushing 1 matches that of the outer wall of the right bushing 2 , and the positions of the oil holes 4 and the oil holes 5 opened on the outer wall of the inner support ring 3 are staggered.

[0024] By means of the oil hole 5 opened on the outer wall of the left bushing 1 and the oil hole 4 opened on the outer wall of the inner support ring 3, the lubricating oil can smoothly enter the inner wall of the inner support ring 3 under the action of the oil hole 4 and the oil hole 5, so as to lubricate the inner wall of the inner support ring 3 and the outer wall of the crankshaft rod 10, so that the inner support ring 3 and the crankshaft rod 10 can rotate more smoothly.

[0025] In a preferred embodiment, the installation position of the dredging rod 9 corresponds to the opening position of the oil through hole 5 , and the outer wall diameter of the dredging rod 9 is smaller than the inner wall diameter of the oil through hole 5 .

[0026] By installing the unblocking rod 9 on the outer wall of the inner support ring 3, when the fixing block 6 and the connecting block 7 are broken due to a large friction force, the inner support ring 3 will swing on the inner walls of the left bushing 1 and the right bushing 2. At this time, during the swinging of the inner support ring 3, the unblocking rod 9 will move back and forth in the inner cavity of the oil through hole 5, thereby unblocking the inner cavity of the oil through hole 5 and preventing the inner cavity of the oil through hole 5 from being blocked by impurities in the lubricating oil.

[0027] In a preferred embodiment, a strong glue is applied to the connection between the outer wall of the fixing block 6 and the outer wall of the connecting block 7, and the thickness of the strong glue does not exceed 2 mm.

[0028] By applying strong glue at the connection between the fixing block 6 and the connecting block 7, the fixing block 6 and the connecting block 7 can be connected under the action of the strong glue. When the oil hole 5 is not blocked, the lubricating oil can smoothly pass through the oil hole 5 and enter the inner wall of the inner support ring 3. At this time, the inner support ring 3 and the crankshaft rod 10 can be normally lubricated, and there will be no break between the fixing block 6 and the connecting block 7. Once the inner cavity of the oil hole 5 is blocked, the lubricating oil cannot smoothly pass through the inner cavity of the oil hole 5. At this time, the inner support ring 3 and the crankshaft rod 10 will lack lubrication, resulting in excessive friction between the inner support ring 3 and the crankshaft rod 10, thereby causing the fixing block 6 and the connecting block 7 to break.

[0029] In a preferred embodiment, there are four oil through holes 5 , and the four oil through holes 5 are respectively opened on the outer wall of the left bushing 1 .

[0030] Through the multiple oil holes 5 opened on the outer wall of the left bushing 1, the lubricating oil is smoothly released into the inner cavity of the left bushing 1 under the action of the oil holes 5, and the lubricating oil passes through the outer wall of the inner support ring 3 and contacts the outer wall of the crankshaft rod 10, thereby achieving lubrication between the outer wall of the crankshaft rod 10 and the inner wall of the inner support ring 3.

[0031] In a preferred embodiment: the outer walls of the left bushing 1 and the right bushing 2 are both provided with limiting holes, and the inner wall diameter of the limiting holes is equal to the outer wall diameter of the locking block 8, and the outer wall of the locking block 8 is installed with a strong magnet.

[0032] By setting a locking block 8 on the outer walls of the left bushing 1 and the right bushing 2, the connection between the left bushing 1 and the right bushing 2 can be achieved under the action of the locking block 8, and the strong magnet installed on the outer wall of the locking block 8 can make the outer wall of the locking block 8 tightly connected with the outer walls of the left bushing 1 and the right bushing 2 under the action of the strong magnet, thereby realizing the installation connection of the left bushing 1 and the right bushing 2 under the action of the locking block 8.

[0033] Working principle: During the use of the above-mentioned equipment, when the left bushing 1 and the right bushing 2 are in normal operation, the lubricating oil will smoothly pass through the inner cavity of the oil hole 5, and then enter through the outer wall of the inner support ring 3, and play a lubricating role between the outer wall of the crankshaft rod 10 and the inner wall of the inner support ring 3. At this time, the inner support ring 3 and the crankshaft rod 10 can rotate smoothly, and the strong glue between the fixing block 6 and the connecting block 7 will not break. Once the inner cavity of the oil hole 5 is blocked by impurities of the lubricating oil during use, the lubricating oil cannot smoothly pass through the inner cavity of the oil hole 5. At this time, the inner wall of the inner support ring 3 and the outer wall of the crankshaft rod 10 cannot be lubricated smoothly, resulting in the inner support ring 3 and The friction between the crankshaft rod 10 increases, and the strong glue between the fixing block 6 and the connecting block 7 will break under the action of the friction. At this time, the inner support ring 3 will swing in the inner cavity of the left bushing 1, but under the action of the clearing rod 9, the inner support ring 3 and the left bushing 1 will not fall off, resulting in eccentric rotation between the inner support ring 3 and the left bushing 1. At this time, the inner support ring 3 makes the outer wall of the clearing rod 9 swing in the inner cavity of the oil through hole 5 during the shaking process, thereby clearing the impurities blocked in the inner cavity of the oil through hole 5, so that the lubricating oil can smoothly pass through the inner cavity of the oil through hole 5, so that the inner support ring 3 and the crankshaft rod 10 can rotate smoothly, thereby avoiding excessive wear of the left bushing 1 and the inner support ring 3.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
