Description
Technical field
The utility model relates to the technical field, particularly a kind of mounting structure of big bus drive motors that big bus drive motors stators and rotators is installed.
Background technology
Big bus drive motors is because of its build heavier (being generally 200 ~ 250KG), because big bus drive motors affects by self gravitation, make its stators and rotators axiality extreme difference after mounting, axiality is generally more than or equal to 1mm, and the assembling of stator, rotor, front end housing and rear end cap is very difficult, firmly need strike and could the bearing being arranged on two ends of rotor be attached together respectively in front end housing and rear end cap with copper rod or weight, also high-precision bearing be impacted simultaneously.Normally first adopting in assembling process is manually inserted in stator by instruments such as lifting, bracing frames by rotor, the form of tightening front and rear cover again completes assembling, easily like this cause the bearings at both ends of rotor and iron core decentraction and cause motor abnormal sound, shake and even also can cause the consequences such as burn-down of electric motor, in order to quality, the raising efficiency of assembling of lifting motor, need the general assembly frock of excellent in design to ensure the Geometrical Tolerance Principle such as motor coaxle degree thus guaranteed performance.In addition, the rotor of big bus drive motors is heavier equally, when needs more exchanging rotor time, be easy to cause rotor to collide stator, finally cause stators and rotators to damage, therefore, do not promote the use of.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides that a kind of structure is simple, reasonable in design, efficiency of assembling is high, assembly qualified rate is high, is convenient to dismounting, solves the mounting structure that a difficult problem, rotor and stator axiality that the bearing of two ends of rotor and rotor core axiality be difficult to ensure be less than or equal to the big bus drive motors of 0.15mm.
The purpose of this utility model is achieved through the following technical solutions: a kind of mounting structure of big bus drive motors, and it comprises workbench, electric machine stand, stator, rotor, rotating shaft and paving help boom hoisting, electric machine stand keeps flat on the table, the rear and front end of electric machine stand is separately installed with front end housing and rear end cap, in electric machine stand, stator is installed, rotor to be arranged in rotating shaft and between axle journal A and axle journal B, the axle journal A of rotating shaft and axle journal B is separately installed with bearing A and bearing B, in the bearing mounting hole that bearing A and bearing B is arranged on front end housing and rear end cap respectively and rotor is arranged in stator, the spindle nose of rotating shaft is arranged on the outside of front end housing, the end of spindle nose is provided with the threaded rod coaxial with rotating shaft, and paving helps boom hoisting by lining, with the bent plate of sleeve, screw, hanger, baffle plate with holes and locking nut composition, lining is enclosed within spindle nose, jacket casing is on lining, the long slab parallel shaft of bent plate arranges and is positioned at directly over electric machine stand, baffle-plate-sleeve is on threaded rod and be fastened on sleeve through locking nut and threaded rod, screw arranges perpendicular to rotating shaft and is pressed on spindle nose through sleeve and lining successively, and described hanger is arranged on the long slab of bent plate, and hanger is arranged on by rotating shaft, bearing A, rotor, front end housing, screw, baffle plate, bent plate, the center of gravity place of lining and locking nut institute building block total weight.
The tapered shape of described spindle nose.
The nominal diameter of described threaded rod is less than the external diameter of spindle nose.
The tapered shape of endoporus of described lining and with spindle nose interference fit.
The utility model has the following advantages: the axiality requirement of (1) guarantee big bus of the present utility model whole motor, after assembling, the axiality of rotor and stator is less than or equal to 0.15mm, therefore without the need to beaing rotor, improve efficiency of assembling and assembly qualified rate, in addition, when needs more exchanging rotor time, only need hoisting auxiliary device be arranged in rotating shaft, just can shifting out rotor level in stator, avoid the scratch between rotor and stator.(2) paving of the present utility model helps the dismounting of boom hoisting very convenient; only need sequentially to back-out locking nut and screw; and order baffle plate and bent plate are taken off from threaded rod; thus bent plate is unloaded from rotating shaft; and in lifting process; Heave Here does not act in rotating shaft, therefore, serves the effect of protection rotating shaft.(3) bearing A of the present utility model is arranged in rotating shaft in the outside of electric machine stand, and bearing B is arranged in rotating shaft after rotor stretches into stator and under visual environment, therefore, be easy to the axiality ensureing bearing A and bearing B and rotor core, effectively solve the difficult problem that the bearing of two ends of rotor and rotor core axiality are difficult to ensure.
