Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subject to the restriction of embodiment.
Embodiment 1, and after the load of the fan drive train increasing in estimation, the utility model has been selected two A belt wheel transmissions.Utilization is contained in the additional strap wheel on belt pulley of engine crankshaft vibration damper, power can be transmitted out from bent axle; According to the position of fan of supporting needs, utilize water pump top, the upper installable mountion plate of joint temperature seat and screw, fan rack arrangement is got on, and fan is revolving part, can not directly not be installed to fixing component, therefore, need to increase therebetween fan shaft part, this fan shaft part must be rotatable through belt transmission, and therefore, these parts need again actionless part and rotating belt pulley.Motionless part is fixed on blower tray, between the belt pulley of rotation and static part, by rolling bearing, connects.Belt transmission, must there is the device of adjusting belt tension, this case utilizes the adjustable Idle wheel parts in position, and the fixed installation of Idle wheel parts, because be difficult to find retaining element on motor, the mounting plate of Idle wheel parts is welded on blower tray, and this piece mounting plate is made to U font groove, precession and back-out by adjusting bolt allow Idle wheel move along U font groove.
Embodiment 2, by accompanying drawing, guarantee that original train is unaffected, and train component are originally vibration damper belt pulley (3), generator (6), water pump (8), and generator (6) is contained in gear chamber (11).This cover fan drive train key increasing will solve the position of fan and installation, the transmission of power, the degree of tightness of fan belt regulates.Below describe embodiment in detail:
Power output: in vibration damper pulley (3), additional strap wheel (4) is installed, additional strap wheel (4) reserves positioning spigot, according to the tapped hole distributing position in vibration damper pulley (3), process corresponding bolt mounting holes, adjust and guarantee that construction bolt can carry the power demand of this train, if transmission capacity is not enough, can change vibration damper pulley (3), increase screw thread hole count, or strengthen the diameter of thread.This example is to adopt the transmission of two A band, and enough in order to guarantee transmission capacity, pulley diameters is at φ more than 170, and additional strap wheel (4) can adopt H8/h8 Spielpassung with vibration damper pulley (3).
The position of fan and installation: according to the supporting needs of complete machine, fan (1) is arranged in to water pump (8) top, and fan (1) must be arranged on rotation component, need to increase fan shaft part (2), and the installation of fan shaft part (2) is fixed, need again to increase the first fan shaft support (7).
The degree of tightness adjustment of fan belt: in order to realize the adjustment of fan belt elasticity, also need to increase Idle wheel parts (10), Idle wheel parts (10) are contained on the first fan shaft support (7).
The enforcement of each component in train:
The A face of fan shaft part (2) is provided with fan face, and B face is stationary plane, is arranged on fan shaft support (7).Belt pulley (13) in fan shaft part (2) is supported on fan shaft (15) by former and later two rolling bearings (14), on upper that face contacting with B face of fan shaft (15), design 4 φ 11 unthreaded holes, more than pitch-row interval 60mm.Belt pulley 1 waist location can reserve grease nipple, to regularly add grease lubrication rolling bearing (14).In order to prevent that dust from entering rolling bearing (14) inside, increases the first dust ring (16) at belt pulley (13) two ends.Two rolling bearings (14) distance before designs according to actual needs, and centre separates with spacer, and for major diameter fan, the moment that two rolling bearings (14) spacing is born is more greatly larger.
The first fan shaft support (7) adopts steel plate 8/Q235-A material to be welded, its A face adds a several screw, with provided with fan spindle unit (2), it is fixing that two tapped holes of A face high order end are used as bracket (12), the bottom of C face is arranged on the thermostat base of motor, and reserve the bolt fixed hole of four φ 11, and D face is as the side fixed plate of the first fan shaft support (7), and two mounting holes overlap with hanger (9) mounting hole.On the steel plate of D face, vertical welding steel plate becomes B face (or steel plate one end right-angle bending of D face is formed), and welds gusset and strengthen.Need to guarantee that B face is parallel with A face, parallelism error is within 0.3mm.On B face, process a U-shaped groove, to Idle wheel parts (10) are installed.The length of U-groove bevel, the displacement difference while being greater than Idle wheel minimum and maximum position.At U-groove bevel end B face dorsal part welding Idle wheel, adjust block, φ 11 through holes are made at block center.
Idle wheel parts (10) structure is similar to fan shaft part (2), be designed with too belt pulley (13), former and later two rolling bearings (14), the second dust ring (21), just in order to install and remove needs, the support of belt pulley is split and is designed to several parts, outside thread is processed in stationary axle wherein (17) one end, the Idle wheel parts core simultaneously coordinating with it processes internal thread, and at the tapped through hole of a M10 of this stationary axle (17) head processing, to twist adjusting bolt (22), the position of controlling Idle wheel parts (10) reaches the suitable elasticity of fan belt.
The structure of bracket (12), is used two orthogonal steel plate 6/Q235-A to be welded, and welds in addition a block plate and strengthen bulk strength as gusset.This two boards respectively with the first fan shaft support (7), contact and thermostat contacts side surfaces, on surface of contact, process respectively the through hole of 2 φ 11, by the bolt of M10, bracket (12) is connected and fixed the first fan shaft support (7) and thermostat base.
Additional strap wheel (4), according to the needs of fan speed ratio, calculate the diameter of belt pulley, for two A band transmission that case adopts herein, the wheel footpath of additional strap wheel (4) should not be less than φ 130, to guarantee transmitted power ability and to guarantee that belt is not because wheel footpath small deflection shortens greatly belt life.Two-wheeled slot pitch is by NBS design.Additional strap wheel (4), right side is processed with positioning spigot, seam length is advisable to be less than the mouth depth 0.5-1mm of vibration damper parts (3), it and the little Spielpassung of vibration damper parts (3), 4 φ 11 through hole distribution circular diameters are with 4 M10 screws of vibration damper parts (3) circle that distributes.The through hole of 2-4 φ 13-φ 17 is stayed in additional strap wheel (4) left side, so that jiggering.
The installation of fan train:
1, with M10 bolt, additional strap is taken turns to (4) and be arranged on vibration damper pulley (3) above, take this case as example, 4 M10 bolts, the circle that distributes is for φ 100, and bolt make-up torque is 30-45N.m.Bracket (12) is separately fixed on thermostat base with 4 M10 bolts and fan shaft part (2) on.
2, use corresponding bolt, the first fan shaft support (7) is arranged on thermostat base, the bolt on right side is through being tightened on thermostat base on again after hanger (9).With 4 M10 bolts, bracket (12) one end is loaded on to first fan shaft support (7) the A face end back side, the other end is loaded on thermostat side, like this, the first fan shaft support (7) all has fixing with both sides above, strength and stiffness are all fine, guarantee that provided with fan (1) and fan shaft part (2) are rear solid and reliable.
3, with the bolt of 4 M10, fan shaft part (2) is arranged on the first fan shaft support (7) above, bolt make-up torque is 30-45N.m.
4, two A bands are put to additional strap wheel (4), fan shaft part (2), adjusting bolt (22) is worn
Cross Idle wheel position on the first fan shaft support (7) and adjust block, Idle wheel parts (10) are put into the
In the U-shaped groove of one fan shaft support (7), two A bands are pressed in the second belt pulley (20) race of Idle wheel parts (10), then load onto stationary axle (1) (not tightening).Twist adjusting bolt (22), additional strap wheel (4) is moved outward, until belt tightness degree is suitable, finally tighten the stationary axle (1) of Idle wheel parts (4).
