Abstract
The utility model relates to the technical field of motors, especially to a motor hold-down device. The motor hold-down device comprises a pressure plate, tension bolts, bots and interference check rings, wherein the pressure plate is disposed on two sides of an iron core and is fixedly connected through the tension bolts and the bolts; the interference check rings are disposed below the pressure plate, are connected through welding, and are provided with solder joints. The motor hold-down device solves a problem of motor vibration very well, eases influence caused by the vibration, and helps to improve work efficiency, bring profits to enterprises and reduce cost investment.
Description
Technical field
The utility model relates to the technical field of hold down gag, especially a kind of motor hold down gag.
Background technology
High rotating speed cage-shaped motor is commonly used to the equipment such as transmission blower fan, in maintenance repair, often finds that some affects production without the high rotating speed cast-aluminum rotor of support motor because of vibration, and some motor oscillating problem is the hard nut to crack that never solves for many years.Along with the operation of surrounding area industrial project, many blower fans can't be produced because of motor oscillating.Can be described as the pot motor vibration cause in actual production diversified, as in: rotor unbalance, bearing wear, bearing chamber through and the bearing outside diameter matching loose.In bearing through loosening with the axle external diameter, stator-rotor iron core is loosening, air gap is uneven, rotor broken bar, stator end cap seam is loosening, the support lower margin is unequal.
The utility model content
Existing at present many blower fans can't be produced because of motor oscillating in order to overcome, and can be described as diversifiedly in actual production as the pot motor vibration cause, and the utility model provides a kind of motor hold down gag.
The technical scheme that its technical problem that solves the utility model adopts is: this motor hold down gag comprises pressing plate, tightening bolt, bolt and interference back-up ring, described pressing plate is as for the both sides of iron core, be fixedly connected with bolt by tightening bolt, the below of pressing plate is provided with the interference back-up ring, the interference back-up ring is by being welded to connect, and is provided with solder joint.
According to another embodiment of the present utility model, further comprise the interior through matching with the axle of both sides unshakable in one's determination respectively of described pressing plate, external diameter is less than the internal diameter of cast aluminium short-circuited conducting sleeve.
The beneficial effects of the utility model are that this motor hold down gag has well solved motor oscillating, has solved the impact that brings because of vibration, has improved operating efficiency, has brought economic benefit to enterprise, has reduced the cost input.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
In figure, 1, pressing plate, 2, tightening bolt, 3, bolt, 4, the interference back-up ring, 5, solder joint.
Embodiment
Fig. 1 is structural representation of the present utility model, comprise pressing plate 1, tightening bolt 2, bolt 3 and interference back-up ring 4, described pressing plate 1 is as for the both sides of iron core, be fixedly connected with bolt 3 by tightening bolt 2, the below of pressing plate 1 is provided with interference back-up ring 4, interference back-up ring 4 is by being welded to connect, and is provided with solder joint 5.Pressing plate 1 interior through matching with the axle of both sides unshakable in one's determination respectively, external diameter is less than the internal diameter of cast aluminium short-circuited conducting sleeve.
In implementation process, pressing plate 1 use 25mm steel plate is made two clamping plates, the internal diameter of clamping plate matches with the axle of both sides unshakable in one's determination respectively, external diameter is less than the internal diameter of cast aluminium short-circuited conducting sleeve, bore the ventilation hole identical with rotor on clamping plate, utilize tightening bolt and clamping plate, rotor core is strained, then the interference axle sleeve that cover is made specially on shaftless tip axis, this cover and clamping plate are adjacent to and intermittently weld with axle.
Overall structure is simple, and has well solved motor oscillating, has solved the impact that brings because of vibration, has improved operating efficiency, has brought economic benefit to enterprise, has reduced the cost input.
