Abstract
The utility model relates to a hollow shaft vibration exciter applicable to vibration screening machinery for particle material grading operation. Existing common vibration sieve vibration exciters in solid shaft structures are high in dead load, bearing load and operating temperature, limited in bearing service life and high in maintenance and replacement difficulty. Reinforcing plates are fixed to two sides of two large side plates of a vibration sieve, a hollow shaft is mounted between the two reinforcing plates, bearings, bearing plates, bearing caps and taper sleeves are mounted at two ends of the hollow shaft, a transmission shaft is mounted between the two taper sleeves, and a flexible coupling is mounted at one end of the transmission shaft connected with a motor. The hollow shaft vibration exciter has the advantages that the integral weight is reduced, motor and bearing loads are reduced, operating temperature of the bearings is lowered, vibration excitation effect is promoted, the service lives of the bearings are prolonged, and manufacturing precision is easy to guarantee.
Description
Technical field
The utility model relates to a kind of novel vibrator, relates in particular to a kind of hollow shaft vibrator that is applicable to the vibration screening machinery of granule materials graded operation.
Background technology
The vibratory sieve vibrator of existing widespread usage adopts the solid shafting structure, and bearing is installed at the solid shafting two ends, and solid shafting rotates with eccentric block and realizes vibratory drive; And employing grease lubrication bearing; Vibrator deadweight is heavier, and bearing load is big, running temperature is high, and the service life of bearing is limited, and it is big that maintenance changes difficulty.The manufacture difficulty of diaxon bearing is big, the making precision is difficult to guarantee.Thereby influence the result of use and the service life of vibrator.
Summary of the invention
The utility model provides a kind of reduction overall weight to above-mentioned deficiency, alleviates the load of motor and bearing, reduces the running temperature of bearing, promotes the service life of exciting effect and bearing, the hollow shaft vibrator that the accuracy of manufacture guarantees easily:
The fixing stiffener in two big side plate both sides of vibratory sieve; Between the stiffener of both sides, hollow shaft is installed; Bearing, bearing dish, bearing cap, tapered sleeve are installed in the hollow shaft two ends; Between the tapered sleeve of both sides, power transmission shaft is installed, an end of power transmission shaft is installed flexible coupling and is connected with motor, and motor drives vibrator work through the flexible coupling that is installed on the power transmission shaft.
For better effect:
Link together through tapered sleeve and power transmission shaft between the bearing cap at two ends.
Fuel tank, fuel tank cap, fuel tank tegillum, oil ga(u)ge are installed on the stiffener at two ends, oil sealing and oil seal cover are housed on the fuel tank cap, coat bearing, bearing dish, bearing cap, tapered sleeve, the power transmission shaft of rotation fully.
Hollow shaft adds on the stiffener that circumference is fixedly welded on both sides with high-strength bolt.
The bearing dish is provided with eccentric weight.
The advantage of the utility model is:
1, hollow shaft is fixed together with the stiffener of high-strength bolt and both sides, and hollow shaft is done circumference or straight-line oscillation with vibrator when operation, does not rotatablely move with the bearing dish.
2. the bearing dish at two ends, bearing cap link to each other with power transmission shaft through tapered sleeve, rotatablely move synchronously together.
3. the parts of participating in rotation have only bearing, bearing dish, bearing cap, tapered sleeve, power transmission shaft and flexible coupling assembly, and its overall weight reduces greatly, thereby the load of motor and bearing is alleviated, and helps promoting the service life of exciting effect and bearing.
4. the close free space of fuel tank, fuel tank cap composition coats rotary parts such as bearing, bearing dish, bearing cap fully, adopts thin oil lubricant and cooling bearing, reduces the running temperature of bearing, the service life of lifting bearing.
5. hollow shaft structure is convenient to make and install, and the accuracy of manufacture guarantees easily.
6. when vibrator need extend, only need extend hollow shaft and power transmission shaft, other parts unchanged, thereby the gross weight of participating in the parts of rotation can not increase does not have adverse effect to the load of motor and bearing, thereby can be applied to large-scale vibratory sieve.
