Summary of the invention
There are the problems referred to above in the utility model to existing technology, has proposed a kind of anti-play structure of main shaft of disc type electric machine, and the anti-play structure of the main shaft of this disc type electric machine can prevent the play of main shaft, improves the running stability of disc type electric machine.
The utility model is realized through following technical proposal: a kind of main shaft of disc type electric machine is prevented the play structure; Disc type electric machine comprises base and main shaft; Base is provided with the installing hole that is used to install main shaft, and above-mentioned main shaft is arranged in the installing hole, it is characterized in that; The anti-play structure of this main shaft comprises three bearings that are provided with between base and the main shaft; Wherein two bearings are the spring bearing of supports main shaft and are fixed in the installing hole, and the 3rd bearing is to overcome the plain thrust bearing of electromagnet pull between motor stator and the rotor and be fixed in the inner port of installing hole, and this plain thrust bearing cooperates with gap of main reinforcement.In the anti-play structure of the main shaft of this disc type electric machine; When electrical power operation, through the design of three bearings, through two bearings to motor shaft to carrying out support fixation; The 3rd bearing can bear electromagnet pull; Let motor operate steadily, thereby effectively overcome the axial endplay of motor, the matched in clearance between bearing and main shaft also makes the easy to assembly of bearing.
In the anti-play structure of the main shaft of above-mentioned disc type electric machine, described two spring bearings are respectively ball bearing and angular contact bearing, and described ball bearing is provided with in the external port of installing hole, and angular contact bearing is arranged between ball bearing and the plain thrust bearing.In the anti-play structure of the main shaft of this disc type electric machine, angular contact bearing is by motor ability bearing axial pushing force, and plain thrust bearing bears the electromagnet pull between axial direction electric machine stator and the rotor.
In the anti-play structure of the main shaft of above-mentioned disc type electric machine, the external port external fixation of described installing hole is useful on the fixedly cover plate of ball bearing, between ball bearing and angular contact bearing, is provided with axle sleeve, between angular contact bearing and plain thrust bearing, is provided with the shaft shoulder.This disc type electric machine is fixed main shaft through cover plate, and the axle sleeve between described ball bearing and the angle bearing withstands ball bearing and angular contact bearing, carries out further screens through the shaft shoulder again, makes motor operate steadily.
In the anti-play structure of the main shaft of above-mentioned disc type electric machine, be with baffle plate on the described main shaft, and the inner of main shaft is provided with rotor, epitrochanterian spring one end withstands on the baffle plate, and the other end is fixed on the rotor.When electrical power, because the magnetic force influence, spring withstands baffle plate, when motor cuts off the power supply, and magnetic force disappearance spring reset.
Compared with prior art, the utlity model has following advantage:
1, selects angular contact bearing for use, motor is operated steadily, effectively overcome the axial endplay phenomenon.
2, select plain thrust bearing for use, born the electromagnet pull between rotor and the stator.
3, selected the structure of three bearings for use, and be matched in clearance between the main shaft, Bearing Installation is more convenient.
