Abstract
The utility model discloses a motor used for a wind power cooler, comprising a motor front end cover (1), a motor rotating shaft (2), three long bolts (3), a motor deep groove ball bearing (4), and a motor bearing inner cover (5); wherein the deep groove ball bearing (4) with a raised grade and an increased load is installed at a front end of the motor rotating shaft (2) for supporting, and an outer ring of the motor deep groove ball bearing (4) is fixed by using the motor bearing inner cover (5) through the three long bolts (3), thereby prolonging the integral service life of the motor. The motor of the utility model has the advantages of high reliability and long service life.
Description
Technical field
The utility model relates to a kind of motor, is specially wind-powered electricity generation field cooler 2.2kW bipolar machine.
Background technology
Being used for domestic wind-powered electricity generation field cooler at present uses the 2.2kW motor all with standard Y2 series threephase asynchronous machine physical dimension, as shown in Figure 2, what its fore bearing adopted is standard 6205 motor deep groove ball bearings (4), it adopts a shaft block ring (6) to occur big play in the axial direction to prevent machine shaft (2), machine shaft (2) goes out axle head, and to be with an external diameter be impeller about 300mm, heavy about about ten kilograms, the motor rotation drives the impeller run-in synchronism together that is enclosed within on the motor shaft when motor passes to three-phase alternating current, thereby plays the cold heat radiation cooling effect of main frame.Yet in wind field ruuning situation, this motor exists many defectives very easily to damage, and specifically is summarized as following 2 points: one, because the imbalance of self produces vibration, vibration causes the motor fore bearing very easily to damage to impeller for a long time when rotating at a high speed; Two, because the motor fore bearing adopts the structural shape of a shaft block ring, because processing and mounting process demand, so can have certain interval all the time between shaft block ring and the fore bearing, cause relatively moving between motor fore bearing outer ring and the front end housing bearing chamber inwall, because the vibration of impeller causes machine shaft in axial direction generation play phenomenon, in the course of time, motor fore bearing outer ring and front end housing bearing chamber inwall rub back and forth, because motor front end housing bearing chamber inwall material hardness will be lower than the fore bearing outer ring, so front end housing bearing chamber inner wall abrasion, cause motor fore bearing " circle of acting as a travelling agent " phenomenon, " sweeping thorax " phenomenon appears in last motor easily, thereby causes burn-down of electric motor.
The utility model content
In order to solve the above-mentioned motor problem of damage easily, the utility model provides a kind of wind-powered electricity generation cooler motor, and the technical solution of the utility model is: a motor front end housing, a machine shaft, three stay bolts, a motor deep groove ball bearing and a motor bearings inner cap are arranged; It is characterized in that: the machine shaft front end is installed one grade of a raising and is strengthened the motor deep groove ball bearing support of load, and fixes motor deep groove ball bearing outer ring with the motor bearings inner cap by three stay bolts.
The utility model adopts the beneficial effect of above technical scheme to be: when electrical power rotates with impeller, heat-dissipating impeller rotates at a high speed and produces vibration, what fore bearing adopted is the deep groove ball bearing that strengthens load, can bear bigger axial load for a long time and can not cause damage of bearings; Motor bearings adopts inside cap to push down the pattern of bearing outer ring, thereby stopped rotor slight play phenomenon is arranged in the axial direction, avoids bearing outer ring and front end housing bearing chamber inwall friction phenomenon, thereby has improved the whole service life of motor.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of existing motor.
Among the figure, 1 motor front end housing, 2 machine shafts, 3 stay bolts, 4 motor deep groove ball bearings, 5 motor bearings inner caps, 6 shaft block rings.
Embodiment
As shown in Figure 1, the utility model has a motor front end housing 1, a machine shaft 2, three stay bolts 3, a motor deep groove ball bearing 4 and a motor bearings inner cap 5; It is characterized in that: machine shaft 2 front ends are installed one grade of a raising and are strengthened motor deep groove ball bearing 4 supports of load, and fix motor deep groove ball bearing 4 outer rings with motor bearings inner cap 5 by three stay bolts 3, thereby the whole service life of motor is lengthened, have reliability height, long service life advantage.
Above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as the technology contents essence of making according to the disclosed technical scheme of this patent is identical or any change or the modification that are equal to, all fall into the scope that this patent comprises.
Claims (1)
