Description
Technical field
The utility model relates to a kind of motor.Particularly relate to the dynamic balancing tooling of a kind of rotor of motor.
Background technology
Rotor all will subtract trochantinian amount of unbalance by dynamic balancing before assembly, to reach the rear object reducing complete machine oscillation of assembling.The general cylindrical size according to rotor, weight, rotating speed select corresponding belt pulley balancing machine or hard bearing balan to balance now.The shaft extension of existing a kind of its one or both ends of rotor is inside iron core, and its moment transmission is undertaken transmitting by the through hole at self Guo Zhou center or spline through hole, and this kind of rotor because cannot directly be placed on the block bearing of balancing machine, and causes balancing.Therefore for this kind of rotor, special dynamic balancing tooling must be made to ensure that it carries out dynamic balancing and dynamically balanced required precision.
Utility model content
The purpose of this utility model is the deficiency existed for above-mentioned prior art, provides a kind of dynamic balancing tooling of rotor, and the dynamic balancing tooling of this rotor is rational in infrastructure, and processing is simple, easy to operate, quick.
The technical solution of the utility model comprises and is connected to corresponding epitrochanterian dummy shaft, the both sides of described rotor are provided with the block bearing be connected on described dummy shaft, one end of described dummy shaft be provided with nut and be positioned at this nut by rotor side bearing holder (housing, cover), the other end of described dummy shaft is provided with lifting gear, described bearing holder (housing, cover) keeps off to bearing dummy shaft is respectively equipped with corresponding to corresponding block bearing, seam before one end of described dummy shaft is provided with and coordinates with bearing holder (housing, cover) endoporus seam, the other end of dummy shaft is provided with rear seam corresponding to the endoporus seam of one end corresponding to rotor.
This kind of rotor can be placed on the enterprising action balance of two-side supporting bearing of balancing machine by dynamic balancing tooling of the present utility model, and ensures dynamically balanced required precision.This tool structure is reasonable, and processing is simple, by pull balance nut with the clamping realizing frock be separated, convenient to operation.The locking length of frock, because there being certain adjustable range, can adjusting according to the different core lengths of rotor, and can repeated multiple timesly use, improve versatility and the utilization rate of frock.
Accompanying drawing explanation
Fig. 1 is the dynamic balancing tooling one example structure schematic diagram of the utility model rotor.
Embodiment
Now also by reference to the accompanying drawings the utility model dynamic balancing tooling is described further by embodiment.
The through hole of the utility model for rotor self You Guozhou center or the feature of spline through hole, an one end is utilized to keep off with bearing, the other end can directly through the balance dummy shaft of rotor shaft hatch, thereon by being furnished with the balance bearing holder (housing, cover) of another band bearing gear, and lock with balance nut, make itself and rotor form one, reach make rotor can be placed on balancing machine two block bearings on carry out dynamic balancing.
Nut matches with the locking screw on dummy shaft, cylindrical is milled with two symmetrical spanner locking planes, in order to be close to integral by balance dummy shaft, balance bearing holder (housing, cover) and rotor lock.Dummy shaft, cage material are the modified material of 40Cr.Nut material is 45# round steel.
As shown in Figure 1, the dynamic balancing tooling of the rotor of the present embodiment comprises balancing machine, is located at the block bearing 10 on balancing machine, the nut 1 of balance, and material is 45# round steel; The bearing holder (housing, cover) 2 of balance and the bearing gear 3 of balance, the dummy shaft 6 of balance and the bearing gear 8 etc. of balance.Its rotor 5 one end shaft extension inside iron core, the through hole at its Shang Youguozhou center.
Block bearing 10 is located at the both sides of the rotor 5 of dummy shaft 6, bearing holder (housing, cover) 2 keeps off 3 and 8 to two bearings dummy shaft 6 is respectively equipped with corresponding to corresponding block bearing 10, one end of dummy shaft 6 is provided with nut 1 and is positioned at the bearing holder (housing, cover) 2 of the corresponding bearing gear 3 of this nut 1 rear band, the other end of dummy shaft 6 is provided with lifting gear 9, seam before one end of dummy shaft 6 is provided with and coordinates with bearing holder (housing, cover) 2 endoporus seam, the other end of dummy shaft 6 is provided with rear seam corresponding to the endoporus seam of one end corresponding to rotor 5.
Rotor 5 connects into a fastening entirety by dummy shaft 6, bearing holder (housing, cover) 2, nut 1.The front seam cylindrical 4 of dummy shaft 6 is that dummy shaft 6 passes the afterbody of rotor 5 shaft through-hole and one section of cylindrical of protuberance, and it matches with the endoporus seam of bearing holder (housing, cover) 2; The rear seam cylindrical 7 of dummy shaft 6 is the cylindrical that dummy shaft 6 matches with rotor 5 endoporus seam; Bearing gear 8 is the bearing gear of dummy shaft 6; Lifting gear 9 is that the lifting after this dynamic balancing tooling and rotor 5 are tightened to one keeps off; Bearing gear 3 is the bearing gear of bearing holder (housing, cover) 2.
When rotor 5 needs to balance, first dummy shaft 6 is passed rotor 5 shaft through-hole, its rear end is positioned with rotor 5 axle endoporus seam by rear seam cylindrical 7; Again bearing holder (housing, cover) 2 is inserted in the front end of dummy shaft 6, is positioned by seam cylindrical 4 before bearing holder (housing, cover) 2 endoporus seam and dummy shaft 6; Then with nut 1, bearing holder (housing, cover) 2, rotor 5, dummy shaft 6 are locked in aggregates together; Keep off 9 finally by another the lifting of the front end gear of corresponding bearing gear 3 and dummy shaft 6 to carry out lifting to the enterprising action balance of block bearing 10.
After rotor 5 has balanced, first hung lower balancing machine, then pulled by spanner and take off nut 1, then struck the front end of dummy shaft 6 with wooden mallet, make dummy shaft 6 exit rotor 5, namely completed the dynamic balancing operation of rotor 5.To keep off 8 gears due to dummy shaft 6 front seam cylindrical 4, rear seam cylindrical 7, bearing be by clamped one time, and grinding Excircle machining out, ensure that its axiality.The bearing gear 3 of bearing holder (housing, cover) 2 is also by clamped one time with its endoporus seam, grinding inside and outside circle, therefore can ensure that the bearing gear 3 at dummy shaft 6 two ends and bearing keep off the axiality of 8, thus meet the dynamic balance accuracy requirement of rotor 5.This dynamic balancing tooling, rational in infrastructure, processing is simple, easy to operate, effectively can ensure that this kind of rotor carries out dynamic balancing and dynamically balanced required precision.
