Abstract
The utility mode relates to a power transmission device at the front part of a diesel engine, comprising a crank pulley, a water pump and an alternator. A water pump multi-wedge belt is connected between the crank pulley and the pony wheel of the water pump belt pulley. An alternator multi-wedge belt is connected between the bull wheel of the water pump belt pulley and the rotating axle belt wheel of the alternator. The utility model is characterized in that more than two tensioner installation holes are arranged on the gear cover of an air compressor; a tensioner axle is fixedly connected in one tensioner installation hole, a tensioner is fixedly connected on the tensioner axle, the edge of the tensioner is tightly pressed on the water pump multi-wedge belt. In the utility model the outside tensioning structure adopted allows a transmission wrapping angle between the crank pulley and the water pump to be increased, helps reduce the vibration, abrasion and skid of the water pump multi-wedge belt in transmission, improve the reliability of the water pump multi-wedge belt and transmission efficiency and prolong the service life of the water pump multi-wedge belt.
Description
Technical field
The utility model relates to a kind of diesel engine front end actuating unit, the front end actuating unit of the WD615 series of more specifically saying so steyr diesel engine.
Background technique
At present, the front end actuating unit of WD615 series steyr diesel engine is to adopt tension structure in two v belt.Because the length of two belts is difficult to be consistent, tightness difference in the transmission easily causes belt slippage and belt early to grind, and belt slippage can reduce transmission efficiency, and belt early grinds the shortening that then causes working life.
Summary of the invention
The purpose of this utility model provides the diesel engine front end actuating unit of a kind of transmission efficiency height, belt long service life.
In order to realize above-mentioned purpose, this diesel engine front end actuating unit, comprise crank pulley, water pump and alternator, be connected with the water pump poly Vbelt between the steamboat of crank pulley and water pump pulley, be connected with the generator poly Vbelt between the rotating shaft belt wheel of the bull wheel of water pump pulley and alternator, its structural feature is to be provided with the Idle wheel mounting hole that quantity is no less than two on the air compressor gear cap, be connected with the Idle wheel wheel shaft on the Idle wheel mounting hole therein, be connected with Idle wheel on the Idle wheel wheel shaft, the wheel rim of Idle wheel is pressed on the water pump poly Vbelt.
Preferably three of the quantity of above-mentioned Idle wheel mounting hole, each Idle wheel mounting hole have the Idle wheel wheel shaft adjusting play of 4-6mm in a lateral direction.
Diesel engine front end actuating unit of the present utility model, the turnbuckle that the rate of tension of generator poly Vbelt is still continued to use former diesel engine and adopted, the adjustment of water pump poly Vbelt rate of tension, then adopted outer tension structure, promptly select to be arranged on the affixed Idle wheel wheel shaft of an Idle wheel mounting hole on the air compressor gear cap diverse location as required, and the fine setting of the adjusting play by Idle wheel wheel shaft tension wheel rim is to the degree that compresses of water pump poly Vbelt, thereby makes the rate of tension of water pump poly Vbelt satisfy powerdriven requirement.
Diesel engine front end actuating unit of the present utility model, owing to adopted outer tension structure, transmission cornerite between crank pulley and the water pump is increased, vibration when having reduced the transmission of water pump poly Vbelt, wear and tear and skid, improved the reliability of water pump poly Vbelt, prolong the working life of water pump poly Vbelt, improved transmission efficiency.
