The water pump belt pulley mainly comprises three belt pulley bodies which are coaxially and fixedly arranged together along the axial direction, and the three belt pulley bodies form a transmission belt mechanism with the crankshaft belt pulley, the air condition compressor belt pulley and the generator belt pulley correspondingly through the transmission belt according to the preset transmission ratio, wherein an automatic tension pulley is arranged at the outer side of a belt ring of the transmission belt between the crankshaft belt pulley and the water pump belt pulley. The belt transmission device based on the technical scheme has the advantages of high transmission efficiency, good reliability and compact structure.
Description
Technical field
The utility model relates to a kind of diesel engine front end belt drive unit, belongs to the belt drive unit technical field.
Background technique
Diesel engine front end belt drive unit utilizes tape handler that the transmission of power of diesel engine is given annex (annex mainly comprises water pump, fan, charging generator, air condition compressor etc.) and it is turned round under suitable rotating speed.Existing diesel front end belt arrangement form is varied, and its kind of drive adopts automotive V-belt more, and is equipped with traditional fixed Idle wheel.Known automotive V-belt driving torque is little, and the life-span is short; And fixed Idle wheel can only regularly be adjusted the tensioning degree of belt, general band all was in tensioning state in the early stage, and pretightening force is excessive, causes belt shaft will carry higher additional load, the wearing and tearing of the power consumption of train and annex bearing all increase greatly, and reduce working life; And in running with tension force reduce gradually along with the growth of belt permanent deformation, and then skidding appears, attachment function is descended.Skid simultaneously and also can cause belt overheated, make the belt inordinate wear, belt life declines to a great extent.Idle wheel is from positive tensioning in addition, and the cornerite of annex wheel is little, and transmission efficiency is low.
Summary of the invention
In view of this, the utility model provides the diesel engine front end belt drive unit of a kind of transmission efficiency height, good reliability, compact structure.
The technical solution adopted in the utility model is:
The utility model diesel engine front end belt drive unit, comprise crankshaft pulley, Water-pump belt wheel, air condition compressor belt wheel and generator belt wheel, and the driving belt that is disposed at above-mentioned belt wheel, described Water-pump belt wheel is for mainly being made up of coaxial three belt wheel bodies that are solidly installed vertically, these three belt wheel bodies form belt mechanism according to predetermined velocity ratio by the corresponding and described crankshaft pulley of driving belt, air condition compressor belt wheel and generator belt wheel, and wherein the zone circle of the driving belt between crankshaft pulley and the Water-pump belt wheel outside is provided with the auto-tensioning wheel.
Based on the diesel engine front end belt drive unit of technical solutions of the utility model adopted with the Water-pump belt wheel be in the middle of drive pulley, and this belt wheel has a plurality of belt wheel bodies, each tape handler has only two belt wheels like this, prevents that a tape handler has a plurality of belt wheels and makes the problem that v-belt contact angle is too small.On the other hand, taeniae telarum's train can reduce the complexity that belt wheel is greatly like this, and it is compact that structure is tending towards.And medium tache reduces, and can further reduce power loss, and actual transfer power is near nominal transmitted power, transmission efficiency height.
At present, the auto-tensioning wheel is applied in the tape handler widely, in this programme, adopt the auto-tensioning wheel that diesel engine front end belt train is carried out tensioning, preferred construction is that this auto-tensioning wheel carries out tensioning to first driving belt between crankshaft pulley and Water-pump belt wheel, and the transmission performance of corresponding tape handler is provided.And outside zone circle, carry out tensioning, and can increase the cornerite of belt wheel, further improve transmission performance.
Above-mentioned diesel engine front end belt drive unit, described auto-tensioning wheel is installed on the gear chamber cover of diesel engine by bolt.
Above-mentioned diesel engine front end belt drive unit, the belt wheel seat of described generator belt wheel are installed on by a rotating shaft and form the swing pair on the frame, and the other end of the belt wheel seat member that this swing is secondary is provided with the turnbuckle of adjusting pivot angle.
Above-mentioned diesel engine front end belt drive unit, described driving belt is a poly Vbelt.
The above-mentioned diesel engine belt drive unit of punctuating, crankshaft pulley in the described driving belt and the driving belt between Water-pump belt wheel are eight slot wedge bands, all the other driving belts are six slot wedge bands.
Description of drawings
Below in conjunction with Figure of description all the technical solution of the utility model be further elaborated, make those skilled in the art better understand the utility model, wherein:
Fig. 1 is the structural representation of diesel engine front end belt drive unit among the utility model embodiment.
Fig. 2 is the structural representation of Water-pump belt wheel.
Fig. 3 is the concrete application schematic representation of diesel engine front end belt drive unit.
Among the figure: 1, crankshaft pulley, 2, first driving belt, the 3, the 3rd driving belt, 4, the air condition compressor belt wheel, 5, second driving belt, 6, generator belt wheel, 7, turnbuckle, 8, Water-pump belt wheel (8a, the big belt wheel of water pump, 8b, water pump small pulley, small pulley in the middle of the 8c, water pump), gear chamber cover 9, the auto-tensioning wheel, 10.
Embodiment
With reference to explanation accompanying drawing 1, it shows a kind of diesel engine front end belt drive unit, comprise crankshaft pulley 1, Water-pump belt wheel 8, air condition compressor belt wheel 4 and generator belt wheel 6, and the driving belt that is disposed at above-mentioned belt wheel, described Water-pump belt wheel is for mainly being made up of coaxial three belt wheel bodies that are solidly installed vertically, these three belt wheel bodies pass through the corresponding and described crankshaft pulley of driving belt according to predetermined velocity ratio, air condition compressor belt wheel and generator belt wheel form belt mechanism, and wherein the zone circle of the driving belt between crankshaft pulley and the Water-pump belt wheel outside is provided with auto-tensioning wheel 9.
Referring to Figure of description 2, this Water-pump belt wheel shown in the drawings has the ladder-type structure, so that inboard driving belt is installed, thus, can design the diameter of each ladder belt wheel body according to predetermined velocity ratio.
For the ease of assembling, preferred mounting type is that described auto-tensioning wheel is installed on the gear chamber cover 10 of diesel engine by bolt.
Because generator is less demanding to the mounting point, therefore, the belt wheel seat of described generator belt wheel is installed on by a rotating shaft and forms the swing pair on the frame, the other end of the belt wheel seat member that this swing is secondary is provided with the turnbuckle 7 of adjusting pivot angle, the generator belt wheel also plays the effect of Idle wheel like this, can obtain required pre-doing the best by adjusting turnbuckle.
