Abstract
The utility model discloses a rocker arm support structure for an engine. A contact surface of the rocker arm support structure which is fixed together with a cylinder cover is provided with a first bolt hole (2), a second bolt hole (3) and a vertical lubricating oil channel (4) formed on the cylinder cover; a horizontal lubricating oil channel (5) for supplying pressure oil to a rocker arm is formed in the support structure; the vertical lubricating oil channel (4) is communicated with the horizontal lubricating oil channel (5); and both sides of the end face of the support structure which is contacted with the rocker arm are provided with a first rocker arm lubricating oil hole (6) and a second rocker arm lubricating hole (7) for supplying pressure lubricating oil to the rocker arm, and are communicated with the horizontal lubricating oil channel (5) in the rocker arm support structure. A rocker arm base and a rocker arm shaft are designed into a whole; and a unique lubricating oil channel structure is adopted, so that pressure lubricating oil in the cylinder cover reaches the rocker arm through the lubricating oil hole and the lubricating oil channel in the rocker arm support structure, and the structure is more compact.
Description
Technical field
The invention belongs to technical field of engines, be specifically related to a kind of engine rocker supporting structure.
Background technique
At present, the rocker shaft bed of most of motors and pitman arm shaft are two parts, and more complicated is installed, and rocker shaft bed only plays the function of installing and supporting pitman arm shaft, and pitman arm shaft plays function lubricated and the support rocking arm.
Summary of the invention
The present invention is exactly for the rocker shaft bed that solves motor and pitman arm shaft are two parts, the problem that more complicated is installed, and purpose provides a kind of compact structure, rocker supporting structure easy for installation.
Technological scheme of the present invention:
A kind of rocker supporting structure that is used for motor, the surface of contact that said rocker supporting structure and cylinder head are fixing is provided with and is used for rocker supporting structure is installed to two bolts hole on the cylinder head, the two symmetric arrays;
The surface of contact that said rocker supporting structure contacts with cylinder head also is provided with vertical oil leab; In the said rocker supporting structure, also be provided with the horizontal oil leab that pressure oil is provided to rocking arm by cylinder cap; Vertically oil leab communicates with horizontal oil leab; Vertically oil leab is between two bolts hole, the parallel axes of axis and two bolts hole; Horizontal oil leab axis and vertical oil leab axis normal, and vertical with the plane, axis place of two bolts hole;
The end face both sides that said rocker supporting structure contacts with rocking arm are provided with two and to rocking arm the rocking arm oilhole of pressure lubrication oil are provided, and communicate with horizontal oil leab in the rocker supporting structure;
Said rocker supporting structure both sides, be provided with to rocking arm play thrust function, the back-up ring that is used for the rocking arm axially locating installs groove;
Said rocker supporting structure, integral body is cross, and horizontal oil leab, rocking arm oilhole, back-up ring are installed groove and are positioned on the criss-cross limit arranged on both sides at the cross center; Two spiro keyhole positions on vertical another limit of cross, the arranged on both sides at the cross center.
Beneficial effect of the present invention:
The present invention is designed to an integral body with rocker arm bracket and pitman arm shaft, and said supporting structure not only has the function of rocker shaft bed, has also had the function of pitman arm shaft.The oil leab structure that it is unique has guaranteed that the pressure lubrication oil in the cylinder head arrives on the rocking arm through the oilhole in the rocker supporting structure, oil leab, makes structure compact more.
