Description
Technical field
The present invention relates to vibrating screen technical field, specially a kind of structure for preventing fire-proof motor cast-aluminum rotor from moving back axis.
Background technique
Vibrating screen is vibrated using reciprocating rotary type caused by oscillator exciting and is worked, and the upper rotation weight of oscillator makes to sieve
Face generates plane whirling vibration, and lower rotation weight then makes compass screen surface generate conical surface rotary vibration, and the effect of synergy then makes
Compass screen surface generates again rotation type and vibrates.
However existing vibrating screen can make the dust from flying being blended in material in screening, it is not easy to it is sized away,
It is easy accumulation instead on sieve, causes mesh to block, influences the working efficiency of screening.In view of the above-mentioned problems, being badly in need of original
Vibrating screen on the basis of carry out innovative design.
Summary of the invention
The purpose of the present invention is to provide a kind of structures for preventing fire-proof motor cast-aluminum rotor from moving back axis, to solve above-mentioned background
Technology proposes that the dust from flying being blended in material can be made in screening, it is not easy to be sized away, be easy accumulation instead and sieving
On the net, the problem of causing mesh to block, influencing the working efficiency of screening.
To achieve the above object, the invention provides the following technical scheme:
A kind of structure for preventing fire-proof motor cast-aluminum rotor from moving back axis, it is characterised in that: including cast-aluminum rotor and shaft, the cast aluminium
Rotor hot jacket in shaft,
It is provided in the shaft including iron core shelves, iron core shelves block machine and bearing guard；The middle part conduct of shaft is arranged in iron core shelves
The positioning section of cast-aluminum rotor,
The outer diameter of cast-aluminum rotor is D and length is L；
The distance of the bearing guard root to iron core shelves block machine root is L2；
L1-L2 is the amount of recovery of cast-aluminum rotor.
Further improvement of these options, as D < 200mm, L < 300mm, amount of recovery (L1-L2) is 0~2mm.
Further improvement of these options, as 200≤D < 400mm, 300≤L < 500mm, amount of recovery (L1-L2) is
2~4mm.
Further improvement of these options, as 400mm≤D, 500mm≤L, amount of recovery (L1-L2) is 4~5mm.
The invention has the following advantages that
1, without planning setting workshop place again, investment and spending is reduced and meets company's unified planning；
2, using mature technology, facilitate worker operation, reduce labor intensity of workers, strong operability, it is ensured that safety；
3, save worker open and inspect motor working hour, save stator be pressed again, terminal box dismounting working hour and avoid lead wire be broken,
Damage saves cast-aluminum rotor back pressure working hour and back pressure shaft is avoided to scrap risk；
4, ensure that motor assembles disposable qualification rate, greatly shorten the motor manufacturing period.
5, ensure the performance and quality of motor, guarantee motor qualification rate.
