Abstract
The invention belongs to the field of a chain transmission system of a diesel engine, and in particular relates to a tensioning mechanism of the chain transmission system of the diesel engine. The tensioning mechanism comprises a tensioning sleeve, a tensioning spring and a tensioning piston; the tensioning sleeve is internally provided with a valve mechanism; the tensioning spring is arranged between the valve mechanism and the tensioning piston; the inner wall of the tensioning sleeve is provided with a groove; the outer wall of the tensioning piston is also provided with a groove; the two grooves are matched through a piston retainer; and the inner wall of the tensioning sleeve is also axially provided with a plurality of lubrication oil grooves. The tensioning mechanism provided by the invention has the advantages that the inner wall of the tensioning sleeve is axially provided with the lubrication oil grooves, oil mist is formed by the lubrication oil grooves when the piston moves, and noise can be lowered better.
Description
Technical field
The invention belongs to diesel engine chain transmission system field, specifically is a kind of tensioning mechanism of diesel engine chain transmission system.
Background technique
In Diesel Engine Technique Field, the transmission adopted gear transmission of diesel engine drives fuel injection pump gear and camshaft gear wheel by crankshaft timing gear through idle gear; This transmission system has to be transmitted accurately, and good reliability, manufacturing process be advantage such as maturation relatively; In the diesel engine field, use the most extensive; But also existing the deficiency of itself, is exactly that its noise can't be controlled effectively, and is one of topmost noise source of diesel engine.In recent years along with the progressively reinforcement of various countries to environmental protection consciousness; Noise also more and more causes the attention of various countries as a kind of environmental pollution; Requirement to the vehicle noise limit value is all proposed in succession; And strict day by day, as the motor in the main noise source of vehicle, its Noise Control becomes the key of car load noise control; The noise that solves the diesel engine transmission system is again the key that solves diesel engine noise, therefore uses a kind of transmission of novel low-noise sound to replace original gear train assembly and is very important.Especially the tensioning mechanism of chain tension piece is most important to Effects of Noise.
Summary of the invention
The present invention is directed to the big shortcoming of diesel engine transmission system noise that exists in the above-mentioned technology, propose a kind of tensioning mechanism of diesel engine chain transmission system, it can effectively reduce the noise of the transmission system of diesel engine.
The technological scheme that realizes the object of the invention is following:
The tensioning mechanism of diesel engine chain transmission system; It comprises tensioning cover, tension spring and tensioning piston, is provided with valve mechanism in the tensioning cover, and tension spring is located between valve mechanism and the tensioning piston; Tensioning cover inwall is provided with groove; The outer wall of tensioning piston also is provided with groove, cooperates through piston stopper between two grooves, also is axially arranged with some oil grooves on the inwall of tensioning cover.
Described valve mechanism comprises the spool of a valve seat and taper, and spool is located in the guide holder through valve spring, and guide holder is located at the tension spring end.
Advantage of the present invention is to be axially arranged with oil groove at the inwall that tensioning is overlapped, and this oil groove forms mist of oil when piston is movable, can better reduce noise.
