Description
Technical field
The utility model relates to a kind of centrifugal blower fan blade wheel dynamic balance calibration device.
Background technology
Because the impeller of all kinds of centrifugal blowers such as waste heat fan, dehumidifier blower fan is because using in high temperature environments for a long time, after conventional maintenance maintenance, still can produce distortion in various degree and transient equilibrium detuning phenomena, blower fan is directly caused to occur the faults such as body vibration is large, noise is high, air quantity is little, normal result of use cannot be reached, also certain influence is caused to production.
Because based on any rotor when rotating around its axis, relative to axis non-uniform mass and can centrifugal force be produced.This uneven centrifugal action will cause vibration on rotor bearing, produces noise and accelerates bearing wear, so that having a strong impact on performance and the life-span of equipment.The rotating parts such as rotor, machine tool chief axis, I. C. engine crankshaft, turbine rotor, gyrorotor and draught fan impeller in the fabrication process, all need could steadily normally to operate through overbalance.
Therefore, equilibrator reduces vibration, improving SNR and carries high-quality requisite equipment.Correct according to the amount of unbalance of data to rotor that equilibrator is measured, can improve the mass distribution of rotor relative to axis, the vibration produced when rotor is rotated or the vibration force acted on bearing reduce within the scope of permission.The balance of usual rotor comprises the measurement of amount of unbalance and corrects two steps, and equilibrator is mainly used in the measurement of amount of unbalance, and the correction of amount of unbalance then often by means of other utility appliance such as drilling machine, milling machine and spot welders, or completes in manual methods.Means for correcting has been become a part of equilibrator by some equilibrator.
The major drawbacks of existing balance correction apparatus is that dynamic balance calibration precision is not too high, to the accessory of some high-precision requirement as: the high precision such as rotor, machine tool chief axis cannot be implemented, thus causes the limitation of equipment.
Utility model content
Its object of the utility model is just to provide a kind of centrifugal blower fan blade wheel dynamic balance calibration device, have can freely dismantle, the feature of portable convenient.
Realize above-mentioned purpose and the technical scheme taked, comprise outside framework, described outside framework is provided with mandrel, mandrel two ends installation shaft bearing; Described base of frame center is provided with and corrects base, datum axle bearing sleeve, corrects base and is provided with 6210 bearings, corrects on base and installs lifting jack; Datum axle bearing sleeve built with 51112 planes and each two of 1212 self-aligning bearings, by fixing bottom datum axle bearing sleeve and outside framework.
Compared with prior art the utility model has the following advantages.
1) this device equipment can carry out dynamic balance calibration to the centrifugal blower fan blade wheel of various model and different size and re-use the reparation damaging impeller;
2) this apparatus structure can freely be dismantled, and support Design is portable, can move to production scene as required and use, extremely convenient;
3) have change greatly before the draught fan impeller service condition after correcting comparatively corrects, the indices such as its noise, power consumption, air quantity all meet technological requirement.

Comprise outside framework 4, as shown in Figure 1 and Figure 2, described outside framework 4 is provided with mandrel 2, mandrel 2 two ends installation shaft bearing 1; Described framework 4 bottom centre position is provided with and corrects base 5, datum axle bearing sleeve 6, corrects base 5 and is provided with 6210 bearings, corrects on base 5 and installs lifting jack; Datum axle bearing sleeve 6 built with 51112 planes and each two of 1212 self-aligning bearings, by fixing bottom datum axle bearing sleeve 6 and outside framework 4.
Described bearing seat 1 is LINK-B6831R bearing seat.
Bearing block base 3 is provided with bottom described bearing seat 1.
Embodiment
This device by LINK-B6831R bearing seat 1, mandrel 2, bearing block base 3, framework 4, correct that the parts such as base 5 form a set of to centrifugal blower fan blade wheel dynamic balance calibration device.
This device is a kind of centrifugal blower fan blade wheel dynamic balance calibration equipment, and the transient equilibrium imbalance post-equalization being mainly used in different model centrifugal blower fan blade wheel uses.Thus, improve service life of equipment, reduce and be equipped with part (bearing seat, bearing, belt pulley, vee belt etc.) consumption, for administration measure provides safeguard.
LINK-B6831R bearing seat
These parts are this apparatus main body drive disk assembly, original-pack imported from America accessory, cast iron quality.Assemble with bearing block base 3, framework 4, framework 4 is installed parts such as mandrel 2 grade.
Mandrel
With diameter 65 millimeters of 45# round steel, according to the draught fan impeller diameter of bore of different size, by the coordinative composition of equipments such as lathe, milling machine processing different model mandrel.Then, after model Matching installation is on impeller, entirety is arranged in LINK-B6831R bearing seat 1 again, uses for timing.
Bearing block base
These parts 10# channel-section steel, is processed by the equipment such as sawing machine, milling machine, is arranged on framework 4.Top is fixedly connected with the assembly of LINK-B6831R bearing seat 1 and mandrel 2 with 4 M12*30 bolts.
Framework
The materials such as this framework 80*80*4 square tube, 12 millimeters of iron plates and diameter 100 weldless steel tube
Processing and fabricating forms, and housing is of a size of: long 1100 millimeters of wide 900 millimeters of * of * are high 800 millimeters.
LINK-B6831R bearing seat 1, mandrel 2, bearing block base 3 are fixed on above it respectively.Subsequent operation can be carried out after using front level meter framework 4 and assembly smoothing thereof to be fixed.
Correct base
