Description
Technical field
The utility model belongs to threephase asynchronous technical field, and it is phase asynchronous that more particularly to a kind of V1 modes are installed
The axle sealing structure of motor non-shaft stretching end.
Background technology
Motor reel typically uses skeleton oil seal, and outside framework oil seal is integrally fixed on bearing cap, during motor rotation
Axle can rub the inner ring of outside framework oil seal, in order to ensure on the service life of outside framework oil seal, motor reel with outside framework oil seal contact-segment
Smoothness requirements it is very high.
Due to its shaft extension down, therefore the bearing of non-shaft stretching end needs plus retaining the threephase asynchronous that V1 modes are installed
Nut and stopping shim, so need to process one section of external screw thread and keyway on axle for installing anti-return nut and stopping shim,
Lead to not mounting framework oil sealing, therefore J-type dust ring can only be used to seal non-shaft stretching end.And J-type dust ring is mounted in
On axle, discord bearing cap contact, it is rotated together as motor shaft is rotated, and its sealing property can not show a candle to outside framework oil seal；Meanwhile,
Because there is a keyway position that J-type dust ring is installed on axle, and J-type dust ring can not seal keyway, thus non-shaft extension section exist it is close
Blind area is sealed, various small impurity can be easily accessible in bearing, so as to influence the life-span of motor.
The content of the invention
Problem to be solved in the utility model is to provide the new of the threephase asynchronous non-shaft stretching end that V1 modes are installed
Profile shaft sealing structure, can effectively solve the non-shaft extension sealing blind zone problem of threephase asynchronous that V1 modes are installed, improve its close
Sealing property.
The axle sealing structure for the threephase asynchronous non-shaft stretching end that the utility model V1 modes are installed, it includes motor
Axle, bearing arrangement, locking mechanism, sealing；Described bearing arrangement includes rear bearing, back end cover for motor, rear internal bearing cover, rear axle
Enclosing cover is held, motor reel is divided into enlarged diameter section, bearing section, reduced diameter section from left to right, and bearing, bearing are provided with its bearing section
It is arranged in the bearing hole of back end cover for motor, the left and right ends of back end cover for motor are respectively arranged with rear internal bearing cover, outside rear bearing
Lid, three's connection is integral, and locking mechanism and sealing are provided with reduced diameter section.
Further, locking mechanism includes stopping shim, anti-return nut；The reduced diameter section of motor reel be divided into thread segment,
Keyway is machined with optical axis section, thread segment, is provided with stopping shim, anti-return nut, optical axis section and is provided with sealing, seal
In the seal mounting hole for being arranged on rear bearing end cover, its inner ring is tightly placed in optical axis section.
Further, described bearing is angular contact bearing.
Further, it is described to be sealed into reinforced seal.
Further, described reinforced seal seals for Double-lip framework.
Further, the diameter D ＜ 2d of motor reel optical axis section, wherein d for motor reel 4 thread segment keyway bottom with
The distance at axle center.
The utility model is that original install is stopped on the motor reel for the threephase asynchronous for installing existing V1 modes
The external thread section of withdrawing nut and stopping shim reduces by a segment distance, then increases by one section of optical axis after external thread section, makes it
Finish meets the requirement of mounting framework oil sealing, when the diameter of optical axis is less than external thread section keyway bottom on axle to axle centre distance
2 times, then just can on this section of optical axis mounting framework oil sealing.
The utility model motor reel can both assemble anti-return nut and stopping shim, and the sealing that bearing is solved again is asked
Topic, so that the sealing property of threephase asynchronous non-shaft stretching end axle is improved, so as to improve the service life of motor.
