Abstract
The utility model discloses a camshaft bearing seat for large -scale engine, one side of bearing frame body is provided with the ring flange of rectangle, the lateral wall position department placed in the middle of circular inner chamber is provided with annular oil groove one, the inlet port that has with annular oil groove intercommunication is left to the ring flange bottom, the inlet port is parallel with the mounting hole, one side of the skew circular inner chamber of inlet port, and it is tangent with annular oil groove, before the ring flange, on the back wall each division have one with the perpendicular communicating pipe joints hole of inlet port, two pipe joints holes constitute " ten " font cross arrangement with the inlet port, keeping away from one side of inlet port bottom the ring flange and extending formation location arch towards the bottom, ring flange bottom position department placed in the middle is provided with the thickening boss, is provided with positioning pin inserting hole in the corresponding position department that thickeies the boss. Before the installation, through location boss and positioning pin inserting hole location and prevent changeing, the bolt behind the spotting on the rethread ring flange is locked, and simple to operate, compact structure, oil circuit are reasonable.
Description
Technical field
The utility model relates to engine component, particularly relates to a kind of for the cam shaft bearing for big h type engine h in engine housing.
Background technology
The existing cam shaft bearing for big h type engine h, adopt casting, the ring flange of rectangle it is provided with in the side of bearing support body, the open holes having four rectangular distributions on ring flange is fixing for installing, the inner chamber of bearing support body is circular, for increasing the intensity of bearing support body and ring flange link position place, bearing support body is circular away from one side of something of ring flange, and the one side of something being connected with ring flange is rectangle. The sidewall middle position place of round cavity is provided with one annular oil groove, is annular oil groove fuel feeding by oil leab, thus realizes lubrication. But existing oil leab is single side fuel feeding, installs limited, and oil duct design is unreasonable, causes the whole cam shaft bearing for big h type engine h not compact, manufacturing cost height.
Practical novel content
The utility model is by optimizing fuel feeding route, it is provided that a kind of easy for installation, compact construction, oil circuit are reasonably for the cam shaft bearing of big h type engine h.
For this reason, the technical scheme that the utility model adopts is: a kind of cam shaft bearing for big h type engine h, comprise bearing support body, the ring flange of rectangle it is provided with in the side of described bearing support body, the inner chamber of bearing support body is circular, bearing support body is circular away from one side of something of ring flange, the one side of something being connected with ring flange is rectangle, the sidewall middle position place of described round cavity is provided with one annular oil groove, it is characterized in that: have bottom described ring flange and the oil supply hole that annular oil groove is connected, and oil supply hole is parallel with open holes, the side of oil supply hole deviation round cavity, and it is tangent with annular oil groove, before ring flange, rear wall respectively has the tubing sub hole that communicates vertical with oil supply hole, two tubing sub holes and oil supply hole form " ten " font arranged crosswise, described tubing sub hole is threaded hole,Bottom described ring flange, side away from oil supply hole extends to form positioning convex towards bottom, and bottom ring flange, middle position place is provided with thickening boss, and the corresponding position thickening boss is provided with steady brace jack.
Preferred as such scheme, the front and rear wall of described bearing support body is provided with some lightening grooves, but bearing support body does not arrange lightening grooves away from the end head of ring flange. Alleviating weight, reduce costs, bearing support body does not arrange lightening grooves away from the end head of ring flange, is to realize compact construction equally.
The beneficial effects of the utility model: when specifically installing, a tubing sub hole taps into oil pipe, and another tubing sub hole is idle to be sealed by stifled head, and the termination of oil supply hole is also by stifled head sealing, lubricating oil enters oil supply hole through one of them tubing sub hole, then enters annular oil groove by oil supply hole. Arranging two tubing sub holes, convenient installation, when limited location, which can according to circumstances select leave unused, which uses, and flexible and changeable, oil supply hole, positioning convex are provided separately respectively, conveniently arranges, saving space; For the cam shaft bearing of big h type engine h, specialized designs positioning boss and steady brace jack, before installation, by positioning boss and steady brace jack location and anti-rotation, it is determined that locked by the bolt on ring flange again behind position. There is the features such as easy for installation, compact construction, oil circuit are reasonable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the B-B sectional view of Fig. 1.
Embodiment
Below by embodiment and by reference to the accompanying drawings, the utility model is described in further detail:
Shown in composition graphs 1 Fig. 3, a kind of cam shaft bearing for big h type engine h, comprises bearing support body, is provided with the ring flange 1 of rectangle in the side of bearing support body, ring flange 1 has the open holes 2 of four rectangular distributions, but is not limited to four.
The inner chamber of bearing support body is circular, and bearing support body is circular away from one side of something of ring flange 1, and the one side of something being connected with ring flange 1 is rectangle. The sidewall middle position place of round cavity is provided with one annular oil groove 3.
Have bottom ring flange 1 and the oil supply hole 4 that annular oil groove 3 is connected, and oil supply hole 4 is parallel with open holes 2. Oil supply hole 4 deviates the side of round cavity, and tangent with annular oil groove 3. Respectively having 5, two tubing sub holes, the tubing sub hole that communicates vertical with oil supply hole 45 in the front and back walls of ring flange 1 and form " ten " font arranged crosswise with oil supply hole 4, tubing sub hole 5 is threaded hole, and one of them diameter is big, and a diameter is little. Extending to form positioning convex 7 away from the side of oil supply hole 4 towards bottom bottom ring flange 1, bottom ring flange 1, middle position place is provided with and thickeies boss 8, and the corresponding position thickening boss 8 is provided with steady brace jack 9. Arrange and thicken boss 8 for arranging steady brace jack 9, be the degree of depth in order to increase steady brace jack 9, ensure that location is reliable.
In addition, the front and rear wall of bearing support body is provided with some lightening grooves 6, but bearing support body does not arrange lightening grooves 6 away from the end head of ring flange 1.
