Description
Technical field
The utility model relates to diesel engine bearing support applied technical field, especially a kind of engine shaft bearing.
Background technique
It is good that diesel engine has fuel economy, the advantages such as powerful, and it is more and more extensive that diesel engine is applied on passenger car; Along with the power moment of torsion of diesel engine and the raising of pressure of explosion, the raising of emission request, the increasing pressure that body is born is high, require also more and more higher to the body structure of cylinder block, the housing construction that four-cycle diesel generally adopts mainly contains divides formula, planer-type and tunnel type equally, what divide that formula and planer-type Boring mill bearing adopt equally is tower structure, and comparatively tunnel type cylinder body is poor for its structural strength; And tunnel type cylinder body has the high feature of structural strength, in requisition for a kind of bearing support rational in infrastructure to meet the demand of Modern high-pressure common rail system diesel engine.
Prior art can not meet the needs of people, for making up prior art deficiency, the utility model aims to provide a kind of engine shaft bearing, it can meet dimensional structure and the intensity of complete machine, reduce the vibration & noise level of motor itself, bearing support adopts high pressure aluminum casting technology, and having good damping result, lightweight low cost of manufacture, workability and assembling capacity can wait advantage well.
For achieving the above object, the utility model by the following technical solutions: a kind of engine shaft bearing, at least comprises thrust plate, bearing shell, oil sealing, tune gap ring and "O"-ring; Described thrust plate and bearing shell are arranged on top and the inner side of bearing support body respectively; Described oil sealing is symmetrical arranged in the left and right sides, bearing support body bottom; The oil sealing that described tune gap ring is arranged in bearing support body interior is symmetrical arranged in the inner part; Described "O"-ring is set in bearing support body upper end.
Further, bearing support outside diameter 204mm, internal diameter 93mm, width 32mm; Bearing support is mounted with by five bolts and rear end of the cylinder block face, and back has stiffening rib to ensure that the rigidity of bearing support, and side has oil leab; Oil provides lubrication through oil channel to bearing shell, bearing shell has arc oil groove, and a watt back of the body pastes jail with bearing support inwall; Described oil sealing includes and supports iron frame and caulking gum, and rubber is arranged on entirety on skeleton and mates with bearing support.
Compared with prior art, the beneficial effects of the utility model are: this engine shaft bearing, and compare traditional cast-iron chock lightweight, level of integration is high, simplify assembly process, are applicable to mass production; Overall structure is simply compact, easily manufactured, practical, is easy to promote the use of.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 3, in the utility model embodiment, a kind of engine shaft bearing, at least comprises thrust plate 1, bearing shell 2, oil sealing 3, adjusts gap ring 4 and "O"-ring 5; Described thrust plate 1 and bearing shell 2 are arranged on top and the inner side of bearing support body respectively; Described oil sealing 3 is symmetrical arranged in the left and right sides, bearing support body bottom; The oil sealing 3 that described tune gap ring 4 is arranged in bearing support body interior is symmetrical arranged in the inner part; Described "O"-ring 5 is set in bearing support body upper end.
Further, bearing support outside diameter 204mm, internal diameter 93mm, width 32mm; Bearing support is mounted with by five bolts and rear end of the cylinder block face, and back has stiffening rib to ensure that the rigidity of bearing support, and side has oil leab; Oil provides lubrication through oil channel to bearing shell, bearing shell 2 has arc oil groove, and a watt back of the body pastes jail with bearing support inwall; Described oil sealing 3 includes and supports iron frame and caulking gum, and rubber is arranged on entirety on skeleton and mates with bearing support.
The utility model is when installing and using: during installation, and bearing support and thrust plate are fixed together, then oil seal pressing on bearing support; Bearing support and cast iron housing face gluing assemble.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any reference character in claim should be considered as the claim involved by limiting.
