Abstract

The utility model discloses a diesel engine valve rocker mounting structure, including valve rocker, rocker arm seat and valve chamber shroud, the rocker arm seat is installed through a plurality of first bolts on the valve chamber shroud, the valve chamber shroud has the screw hole that lets first bolt male, and the rocker arm seat has the through-hole that lets first bolt pass. The utility model discloses a diesel engine valve rocker mounting structure, valve rocker and rocker arm seat dress do not receive sprayer and valve spring on the valve chamber shroud yet, and the space is sufficient in the influence of sprayer clip. Sufficient design space reduces the spare part design degree of difficulty, and the increase strength reduces the risk, improves engine reliability to improve valve train's reliability, the sufficient reduction sprayer risk of leaking gas of sprayer clip space design simultaneously.

Description

Valve rocker mounting structure of diesel engine
Technical Field
The utility model belongs to the technical field of the engine, specifically speaking, the utility model relates to a diesel engine valve rocker mounting structure.
Background
The fuel injector of the fuel system is usually arranged in the middle of a combustion chamber of the engine, the valve is arranged around the fuel injector, the rocker mechanism for driving the valve is simultaneously arranged around the fuel injector, and the rocker seat is usually arranged on a cylinder cover. Parts such as a rocker arm, a rocker arm seat, an injector clamp, a valve, a spring and the like are arranged around the injector, so that the peripheral space of the injector is locally promoted, the injector is difficult to arrange, and the arrangement is sometimes satisfied by sacrificing the strength of the parts, so that the reliability problem is easy to occur.
SUMMERY OF THE UTILITY MODEL
The utility model discloses aim at solving one of the technical problem that exists among the prior art at least. Therefore, the utility model provides a diesel engine valve rocker mounting structure, the purpose makes things convenient for the installation of the peripheral spare part of sprayer.
In order to realize the purpose, the utility model discloses the technical scheme who takes does: the valve rocker mounting structure of the diesel engine comprises a valve rocker, a rocker seat and a valve chamber cover, wherein the rocker seat is mounted on the valve chamber cover through a plurality of first bolts, the valve chamber cover is provided with threaded holes for the first bolts to insert, and the rocker seat is provided with through holes for the first bolts to pass through.
The valve rocker is mounted on the rocker base through a rocker shaft, and the rocker shaft is mounted on the rocker base through a second bolt.
The valve rocker arm and the rocker arm seat of the diesel engine valve rocker arm mounting structure of the utility model are mounted on the valve chamber cover cap and are not affected by the oil injector, the valve spring and the oil injector clamp, and the arrangement space is sufficient; the sufficient design space is beneficial to reducing the design difficulty of parts, increasing the strength, reducing the risk and improving the reliability of the engine, so that the reliability of a valve actuating mechanism is improved, and meanwhile, the clamp space of the oil injector is designed sufficiently to reduce the air leakage risk of the oil injector; the fuel injector and the valve actuating mechanism are core parts in the engine, and the reliability of the engine body is improved by improving the reliability of related parts.
Drawings
The description includes the following figures, the contents shown are respectively:
FIG. 1 is an exploded view of the mounting structure for a valve rocker of a diesel engine of the present invention;
labeled as: 1. a valve rocker arm; 2. a rocker arm seat; 3. a valve chamber cover; 4. a cylinder cover; 5. a rocker shaft; 6. a first bolt; 7. and a second bolt.
Detailed Description
The following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings, for the purpose of helping those skilled in the art to understand more completely, accurately and deeply the conception and technical solution of the present invention, and to facilitate its implementation.
It should be noted that, in the following embodiments, the "first" and "second" do not represent an absolute distinction relationship in structure and/or function, nor represent a sequential execution order, but merely for convenience of description.
As shown in fig. 1, the utility model provides a diesel engine valve rocker 1 mounting structure, including valve rocker 1, rocking arm seat 2 and valve chamber shroud 3, rocking arm seat 2 installs on valve chamber shroud 3 through a plurality of first bolts 6, and valve chamber shroud 3 has the screw hole that lets first bolt 6 male, and rocking arm seat 2 has the through-hole that lets first bolt 6 pass.
Specifically, as shown in fig. 1, the valve chamber cover 3 is fixedly mounted on the top surface of the cylinder head 4 by bolts, and the rocker arm seat 2 is located between the valve chamber cover 3 and the cylinder head 4. During installation, the first bolt 6 is inserted into the threaded hole of the valve chamber cover 3 after passing through the through hole on the rocker arm base 2, and the rocker arm base 2 can be fixed on the valve chamber cover 3 by tightening the first bolt 6.
In the present embodiment, as shown in fig. 1, the rocker arm support 2 is mounted on the valve chamber cover 3 by means of six first bolts 6, and accordingly, six threaded holes are provided in the valve chamber cover 3 and six through holes are provided in the rocker arm support 2.
As shown in fig. 1, the valve rocker arm 1 is mounted on the rocker arm base 2 through the rocker shaft 5, the rocker shaft 5 is mounted on the rocker arm base 2 through the second bolt 7, the rocker arm base 2 has a threaded hole into which the second bolt 7 is inserted and a mounting hole through which the rocker shaft 5 passes, the rocker shaft 5 has a through hole through which the second bolt 7 passes, the axis of the second bolt 7 is parallel to the axis of the first bolt 6, and the axis of the rocker shaft 5 is parallel to the length direction of the cylinder head 4. The mounting hole is located at the center of the rocker-arm seat 2 in the length direction, and six first bolts 6 are symmetrically distributed on two opposite sides of the mounting hole.
The invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above-described manner. Various insubstantial improvements are made by adopting the method conception and the technical proposal of the utility model; or without improvement, the above conception and technical solution of the present invention can be directly applied to other occasions, all within the protection scope of the present invention.
