Description
Technical field
The present invention relates to a kind of engine accessory system, particularly relate to a kind of accessory wheel system of dynamo engine of belt drives.
Background technique
It is active force that Vehicular engine accessory system is exactly with the bent axle belt pulley, drives each annex of motor by accessory belt, generator for example, and air compressor, power steering pump or the like, and then realize the proper functioning of motor.Along with development of times, the user is to the noise of engine accessory system, higher requirement has been arranged working life, this just requires will be by reasonably arranging when engine accessory system designs, make cornerite, safety clearance, parameters such as moderate are reached a desirable state, ensure the proper functioning of each annex.
At present, some small-sized generator set also adopts engine-driving.These two kinds of motors are owing to the application target difference, and its accessory belt drive system also has very big difference.Dynamo engine is owing to be to be used to drive generator set, and the assembly that relates to has: generator, bent axle belt pulley, cooling fan belt wheel, cooling fan driving mechanism, generator adjusting arm etc.
In addition, in the modern designs, more and more higher to the size requirement of motor.Further be exactly to require engine structure compact as much as possible, and one of accessory belt drive system boundary conditions key factor that to be the motor external boundary will consider, this size to accessory belt drive system is just had higher requirement.And along with the continuous rising of people to the factor attention rates such as working life of the noise of motor, accessory system, the engine accessory power rating belt drive system must and guarantee at security of operation to arrange under the prerequisite in working life, and make every effort to compact.
Summary of the invention
The objective of the invention is to the deficiency that exists in the existing dynamo engine accessory wheel system, a kind of accessory wheel system of dynamo engine be provided, this gear train features reliable work, simple in structure, arrange compact.
The technical solution adopted for the present invention to solve the technical problems is: a kind of accessory wheel system of dynamo engine, be arranged on the engine cylinder-body front end, and comprise the crankshaft pulley, blower pulley, the generator that connect by the belt order; It is characterized in that: between described generator and crankshaft pulley, belt stretcher is set; Described belt stretcher comprises the generator adjusting arm that is fixed on the engine cylinder-body, the camber line adjustment hole is set on the described adjustment arm and adjusts screw rod, described adjustment screw flight is connected in slide block movable on the adjustment hole, and described generator is fixed by Bolt Connection slide block and adjustment arm.
Further, described blower pulley is the blower pulley assembly, comprise the bearing race that is fixed on the engine cylinder-body front end, be interference fitted in the interior contact bearing of bearing race and the circlip of axial limiting contact bearing, the inner ring interference fit of described contact bearing connects fan drive shaft; Described fan drive shaft connects breast wheel, and described breast wheel is by the Bolt Connection blower pulley.
Good effect of the present invention: owing to be to be used to drive generator set, so its accessory belt drive train has bigger difference than conventional Vehicular engine accessory system.The assembly that relates to has only belt wheel, generator and the generator adjusting arm tightening belt mechanism of engine crankshaft belt wheel, cooling fan.Therefore, this accessory system is less owing to relating to assembly, and structure is simple relatively, does not adopt automatic tensioner from falling cost consideration, but reaches the tensioning of belt by adjustable generator adjusting arm.The pulley assemblies of cooling fan is because its radial load that is born in the course of the work is bigger, so adopt high-intensity biserial contact bearing.Thereby realized the proper functioning of cooling fan, generator, the safety of drive system and reach working life of target.Whole system has reached the very compact type of high level.
Below with reference to drawings and Examples, the present invention is carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is an accessory wheel system schematic representation of the present invention.
Fig. 2 is fan pulley assemblies sectional view among the present invention.Connecting between signal fan and the blower pulley.
Fig. 3 is belt stretcher organigram among the present invention.
Among the figure: 1. crankshaft pulley, 2. the blower pulley assembly, 3. generator, 4. tension device, 5. belt, 6. adjust arm, 7. adjust screw rod, 8. slide block, 9. adjustment hole, 10. bearing race, 11. contact bearings, 12. fan drive shafts, 13. circlips, 14. breast wheels, 15. blower pulleys, 16. bolts.
Embodiment
By static state and dynamic arrangements calculate the back determine between generator belt wheel and the crankshaft pulley the safety clearance and and crankshaft pulley between minimum span, the rate of skidding of belt and the relevant parameters such as radial load of belt wheel.
Shown in Fig. 1,3, a kind of accessory wheel system of dynamo engine is arranged on the engine cylinder-body front end, comprises the crankshaft pulley 1, blower pulley 2, the generator 3 that are connected by belt 5 orders.Between described generator 3 and crankshaft pulley 1, belt stretcher 4 is set.Described belt stretcher 4 comprises the generator adjusting arm 6 that is fixed on the engine cylinder-body, on the described adjustment arm 6 camber line adjustment hole 9 is set, movable slide block 8 is arranged, the slide block 8 of described adjustment screw rod 7 scyewed joint activity on adjustment hole 9 on the described adjustment hole 9.Described generator is by bolt and slide block 8 and adjust arm 6 and be fixedly connected.Generator will rotate along regulating camber line hole (diameter 8.5mm) along with slide block, by the measurement of dynamometer, make belt reach design tension force.Crankshaft pulley 1, blower pulley 2 these two belt wheels are the troughed belt wheel.
As shown in Figure 2, described blower pulley is the blower pulley assembly, comprise the bearing race 10 that is fixed on the engine cylinder-body front end, be interference fitted in the contact bearing 11 in the bearing race 10 and the circlip 13 of axial limiting contact bearing, the inner ring interference fit of described contact bearing 11 connects fan drive shaft 12; Described fan drive shaft 12 connects breast wheel 14, and described breast wheel 14 is by bolt 16 linked fan belt wheels 15.This assembly material adopts No. 45 steel, because its radial load that is born in the course of the work is bigger, so adopt high-intensity double row bearing.The cooling fan pulley diameters is bigger, is not used so compress this mode by bolt add bearing in the middle of belt wheel after.But designed a kind of independently blower pulley assembly.Blower pulley is bolted on the breast wheel by 4 M10*20's, and bearing race is fixed on the baffle plate of motor head.Along with the rotation of belt and then realized the proper functioning of cooling fan.Dynamo engine all is to move under same operating mode usually, and rotating speed is 3600 rev/mins, and cooling fan requirement rotating speed is 3000 rev/mins.Therefore, blower pulley is 3600/3000 with crankshaft pulley diameter ratio.Therefore the cooling fan pulley diameters is defined as 144mm.
