Description
Technical field
The utility model belongs to structure technique, is specifically related to a kind of tensioning mechanism of diesel engine drivign belt.
Background technique
Along with the raising that people require automobile reliability and riding comfort, attenuating vibration & noise has become the minimum requirements to commercial vehicle riding comfort.One of principal element as vibration or noise is exactly that the rate of tension of driving engine belt regulates, and it will directly affect stationarity and the transmission efficiency of driving mechanism.Traditional diesel engine belt tension manually pulls generator to make belt tension, and tensioning degree is controlled by assembly crewman's feel, except belt adjustment inconvenience, is mainly difficult to the conformity ensureing its degree of tightness.Lax meeting causes transmission efficiency to decline, and throws switch, and even occurs belt channelling fault; Tension then can cause vibration not steady, and belt is greatly stressed, is transmitted the stressed increasing of component, even occurs breaking axis.Therefore, the reliability of belt tightening to raising driving parts, the reduction vibration that adjust standard are very crucial.
Summary of the invention
The purpose of this utility model is to provide a kind of tensioning controlling mechanism of diesel engine drivign belt, on the convenient basis regulated, relatively shortens complete machine Belt Length, reaches the object reducing vibration & noise.
The technological scheme taked for realizing the purpose of this utility model is: support is provided with three bar holes, three bar hole distributions triangular in shape, and support is fixed on gear chamber cover through bar hole by construction bolt.Idle wheel is placed in mid-stent.Between back-end support two bar holes, process a right angle bent face, this bent face is provided with a draw-in groove.Gear chamber cover is provided with a boss, and boss is provided with the tapped hole that is installed adjusting bolt, and ring-shaped clip is equipped with on the top of adjusting bolt, and clip embeds in the draw-in groove of bent face.Crank pulley, water pump pulley and generator pulley are linked together by belt wrap, Idle wheel is between crank pulley and generator pulley, drive support and Idle wheel to move by rotating adjusting bolt, the rate of tension realizing belt regulates.
Its theory structure is, Idle wheel and support are fixed, and crank pulley, water pump pulley and generator pulley are connected by belt, and Idle wheel is between crank pulley and generator pulley.Three bar holes that support is provided with roughly can determine the distance and position of Idle wheel and crank pulley, water pump pulley and generator pulley 3 trains, also belong to the preconditioning of belt tightening.After support (Idle wheel) is fixing a little, the thin tuning of belt slack rate of tension makes Idle wheel (support) carry out in the fine motion displacement of three bar holes by adjustment adjusting bolt exactly.
The beneficial effect of feature of the present utility model and generation is, supporting structure is simple, belt tightening is easy to adjust, ensures the conformity of belt tension dynamics.This device can reduce the vibration of diesel engine entirety, improves bel-drivenn reliability and transmission efficiency, and extends the working life of belt, makes engine maintenance maintain convenient simultaneously.
Accompanying drawing explanation
Accompanying drawing is Principles and methods figure of the present utility model.
Embodiment
Structure of the present utility model is further described by specific embodiment below in conjunction with accompanying drawing, but the technology that the utility model is contained is not limited to following embodiment.
Diesel engine belt tension controlling mechanism, comprises support, gear chamber cover, Idle wheel, crank pulley, water pump pulley, generator pulley, belt, construction bolt and adjusting bolt etc.Its structure is: support 1 is provided with three bar holes, three bar hole distributions triangular in shape, and support is fixed on gear chamber cover 2 through bar hole by construction bolt 8, and Idle wheel 3 is placed in mid-stent.Between back-end support two bar holes, process a right angle bent face, this bent face is provided with a draw-in groove, and gear chamber cover is provided with a boss, and boss is provided with the tapped hole that is installed adjusting bolt 9.Ring-shaped clip is equipped with on the top of adjusting bolt, and clip embeds in the draw-in groove of bent face.Crank pulley 4, water pump pulley 5 and generator pulley 6 are intertwined and connected together by belt 7, and Idle wheel is between crank pulley and generator pulley.Drive support and Idle wheel to move by rotating adjusting bolt, the rate of tension realizing belt regulates.
For four-cylinder diesel engine.Crank pulley of diesel engine rotates, and rotated by belt drive water pump pulley and generator pulley, the tensioning degree of belt is regulated by the position of Idle wheel.The belt 4 of diesel engine adopts poly Vbelt, and the external diameter 90mm of Idle wheel, is arranged on tension pulley support by bolt.The material of support is Q235 steel plate, the width 9mm of three bar holes, length 39mm, and 3 construction bolts are the standard bolt of M8 × 20, and support is fixed on gear chamber cover.
Right angle bent face on support is provided with a draw-in groove, groove width 8.5mm.The bolt head of tensioning adjusting bolt is provided with a ring-shaped clip, this ring-shaped clip diameter 8mm, wide 5.5mm, clip two ends circular outer diameter 18mm.
Clip loads in the fluting of support bending part.Gear chamber cover there is a boss, boss has the construction bolt hole of tensioning adjusting bolt, the screw section of adjusting bolt is screwed in this bolt hole, when rotating adjusting bolt, adjusting bolt can regulate direction to move along tensioning, and the ring-shaped clip of tensioning adjusting bolt head will block support, itself and adjusting bolt are moved, support moves together with Idle wheel, during by belt tension to the tightness needed, support and gear chamber cover is fixed by 3 construction bolts.
