Abstract
The utility model discloses a bearing pedestal for a camshaft, comprising a bearing pedestal body (6) arranged at the upper part of a cylinder cover (1). The bearing pedestal body (6) comprises more than two camshaft mounting holes (5); connecting holes which are detachably connected with the cylinder cover (1) are arranged on the bearing pedestal body (6); mutually communicated lubricating oil ducts are arranged inside each camshaft mounting hole (5) on the bearing pedestal body (6); the lower end of each lubricating oil duct is communicated with a cylinder cover oil duct (7) of the cylinder cover (1). The utility model adopts the structure in which the bearing pedestal body is detachably connected with the cylinder cover and the lubricating oil inside the cylinder-cover oil duct can pass through the lubricating oil duct and flow into the camshaft mounting holes to lubricate the camshaft; thus, the processing and the assembly of the utility model are more convenient so as to reduce the processing cost and increase the selectability of the small space arrangement of the cylinder cover, so that the structure of the cylinder cover can be simpler and tighter.
Description
Technical field
The utility model relates to auto parts and components, especially relates to a kind of camshaft bearing bush seat.
Background technique
At present, the common arrangement of the valve mechanism of motor is an overhead camshaft, its support unit is a camshaft bearing bush seat, camshaft bearing bush seat is positioned at cylinder cap top, and it comprises plural camshaft mounting hole, and camshaft bearing bush seat and cylinder cap are for forming the foundry goods of one, arrange relative difficulty with the processing and lubrication oil duct, processing cost is higher, and the setting tool of assembling valve mechanism uses very inconvenient owing to be subjected to spatial constraints.
The model utility content
Technical problem to be solved in the utility model is: a kind of camshaft bearing bush seat is provided, and this camshaft bearing bush seat is convenient to arrange and the processing and lubrication oil duct, cuts down finished cost, and is easy to assembly.
Solve this technical problem, the technical solution of the utility model is: a kind of camshaft bearing bush seat, comprise the bearing support body that is positioned at cylinder cap top, this bearing support body comprises plural camshaft mounting hole, described bearing support body is provided with the attachment hole that removably connects with cylinder cap, be provided with the oil leab that communicates in each camshaft mounting hole on the described bearing support body, the lower end of described each oil leab is connected with the cylinder cap oil duct of cylinder cap.
The lower end of each oil leab on the described bearing support body is communicated with concourse with described cylinder cap oil duct and is provided with the bearing cap oil collecting hole.
The described oil leab that communicates with each camshaft mounting hole is an inclined oil hole of air, and inclined oil hole of air is the through-hole structure that is in tilted layout.
Described bearing support body is provided with the projection of location when being used to process and assemble.
The quantity of described camshaft mounting hole is two.
The attachment hole that is connected with cylinder cap on the described bearing support body is the bolt hole of three equidistant intervals.
A kind of camshaft bearing bush seat of the utility model adopts such structure, bearing support body and cylinder cap removably connect, lubricant oil in the cylinder cap oil duct enters the camshaft mounting hole by inclined oil hole of air and can be lubricated camshaft, compared with prior art, processing is more convenient with assembling, has reduced processing cost, has increased the alternative of the little spatial arrangement of cylinder cap, be convenient to arrange oil leab, the cylinder cap structure is concision and compact more.
