Description
Technical field
Patent of the present invention relates to machine field, especially a kind of variable frequency high-speed motor bearing removal ring.
Background technology
Existing high-speed induction motor (band gimbal) majority is employing angular contact bearing, installation, grease lubrication and interior oil cap protect the mode of oil back-to-back in pairs.Due to the inner ring of the higher bearing of rotating speed and outer shroud thinner, and, the bearing arrangement that rotating speed is higher is more accurate, price is more expensive, therefore, when variable frequency high-speed motor needs to carry out bearing removal, generally all never adopt traditional holder of drawing to carry out pressure dismounting to bearing, rotor due to variable frequency high-speed motor is all configured with gimbal (duplicate removal method dynamic balance checking), therefore, the bearing removal of variable frequency high-speed motor is all adopt stripping ring to coordinate interior oil cap and bolt to be screwed into bearing removal (support) to get off.Its method for dismounting is: stripping ring (upper semi-ring and lower semi-ring) is positioned over bearing inner ring root place, the upper semi-ring of stripping ring and lower semi-ring colligation are fixed by stripping ring groove with iron wire etc. again, be screwed into until prop up gimbal with 3-4 root bolt respectively from the screw of internal bearing cover again, continue again to be screwed into bolt respectively, bearing removal (support) can be got off.The method bearing inner ring uniform force, can ensure that retainer and steel ball are without any damage after dismantling, but, adopt iron wire or rope etc. carry out colligation fix the upper semi-ring of stripping ring and lower semi-ring time, the time spent is more, Comparision difficulty, and, consideration is needed to subtract trochantinian amount of deflection due to during design high-speed electric expreess locomotive, generally all can by bearing shoulder near gimbal position, to reduce bearings at both ends length of support, therefore, only there is 6mm-10mm in the bearing of pot motor and the gap of interior oil cap seam, at this moment, common stripping ring because of size wide, bearing inner ring root place cannot be put at all, therefore, finally only have and adopt destructive dismounting, larger economic loss is caused to enterprise.
Summary of the invention
The object of this invention is to provide a kind of structure simple, easy to use, guarantee the variable frequency high-speed motor bearing removal ring of bearing removal serviceability rate.
The employing technical scheme of this reality invention, comprise two left dismounting semi-rings and two right dismounting semi-rings, there is outward flange the left side of its left dismounting semi-ring, the outward flange diameter of described left dismounting semi-ring is equal with bearing inner ring external diameter, there is inner stopper the right side of left dismounting semi-ring, the inner stopper diameter of described left dismounting semi-ring is slightly less than the left side seam diameter of right dismounting semi-ring, two left internal diameters of dismounting semi-ring composition and the shaft shoulder equal diameters of variable-frequency motor, external diameter is slightly less than the large footpath of the oil groove of oil cap in bearing;
There is male half coupling the left side of right dismounting semi-ring, the male half coupling diameter of described right dismounting semi-ring is slightly less than the inner stopper diameter of left dismounting semi-ring right side, there is inner stopper the right side of right dismounting semi-ring, the inner stopper diameter of described right dismounting semi-ring is slightly larger than the oil groove path of oil cap in bearing, two right internal diameters of dismounting semi-ring composition and the shaft shoulder equal diameters of variable-frequency motor, external diameter is slightly less than the large footpath of the oil groove of oil cap in bearing.
Structure of the present invention is simple, uses easy to operate, fill up because of in bearing and bearing between oil cap spacing narrow, the blank of the intact dismounting of bearing cannot be carried out, bring the features such as larger economic benefit for enterprise.
