Abstract
The utility model discloses a test device for a screening test of a bearing component. The test device comprises a motor and a connecting piece fixedly connected with a motor rotor of the motor in a detachable manner, wherein the connecting piece comprises a fixing part matched with the front end surface of the motor rotor in a press-fit manner; a connecting part extending back to the motor rotor is arranged at the outer edge of the fixing part; a stop edge for being matched with a circular ring of a bearing support in a press-fit manner is arranged at the tail end of the connecting part; and a threaded hole corresponding to a mounting hole on the bearing support is formed on the stop edge. The bearing support, even the whole bearing component, can be fixed on the motor rotor through the connecting piece, and the screening test of the bearing component is further realized.
Description
Technical field
The utility model relates to the proving installation that a kind of bearing assembly shaker test is used.
Background technology
Bearing assembly is the execution unit of the key of satellite momenttum wheel; The precision of bearing assembly, life-span, reliability and performance directly influence control accuracy, life-span, reliability and the performance of satellite momenttum wheel; Bearing assembly must carry out shaker test before payment, need the bearing seat of bearing assembly be fixed on the rotor of brshless DC motor during shaker test; And the axis that guarantees bearing seat is consistent with the axis of rotor; Because bearing block structure is more special, constitute by cylindrical shell and the annulus that is set on the cylinder body outer wall, offer the annular U type groove that is provided with at interval from inside to outside on the end face of annulus; And be positioned at the outer U-lag outside on the annulus and offer the mounting hole that circumferentially is provided with at interval along it; And the installed surface of the rotor of drive bearing assembly is the plane, and bearing seat and rotor can't directly be installed, and therefore can't realize the shaker test of bearing assembly.
The utility model content
The purpose of the utility model provides a kind of proving installation that can realize the bearing assembly shaker test.
The utility model adopts following technical scheme: a kind of bearing assembly shaker test is used proving installation; Comprise motor and the web member that is removably fixed with rotor; Said web member comprises with the rotor front end face and is adjacent to the fixed part that cooperates; The outer rim of fixed part has the connecting portion that rotor dorsad extends, and the end of connecting portion has and is used for being adjacent to the retaining edge that cooperates with the annulus of bearing seat, offer on the retaining edge be used for bearing seat on the corresponding threaded hole of mounting hole.
Said web member is and the opening of the coaxial setting of the rotor tubular structure of rotor dorsad that said connecting portion is the barrel of web member.
Said retaining is along being outward extending annular retaining edge.
Offer on the said fixed part and the cylinder body outer wall of the bearing seat pilot hole that the cylindrical shell of the confession bearing seat that cooperates passes through that coincide.
The internal diameter of said web member is greater than the external diameter of the outer U type groove of bearing seat.
Adopt the bearing assembly shaker test of said structure to use proving installation; Because the fixed part outer rim of web member has the connecting portion of rotor extension dorsad; The end of connecting portion has the retaining edge, retaining along on offer with bearing seat on mounting hole threaded hole one to one, can bearing seat be fixed on the web member through screw; And the cylindrical shell of bearing seat can stretch into the connecting portion inboard; Simultaneously the fixed part of web member and the front end face of rotor are adjacent to and cooperate and be removably fixed with rotor, and the dependence web member can be fixed on bearing seat even whole bearing assembly on the rotor, and then the shaker test of realization bearing assembly.
Description of drawings
Fig. 1 is the example structure synoptic diagram of the utility model.
Embodiment
The utility model bearing assembly shaker test is with the embodiment of proving installation: as shown in Figure 1; Comprise the motor (not shown); Motor is a brshless DC motor; The annular retaining edge of receiving in rotor 3 front ends of motor have offers along its circumferential spaced apart mounting hole on the annular retaining edge of rotor 3.The front end of rotor 3 is provided with web member 2; Web member 2 is and the opening of the rotor 3 coaxial settings tubular structure of rotor 3 dorsad; Offer on the aft bulkhead of web member 2 with rotor 3 on the threaded hole of the corresponding one by one setting of mounting hole; After the front end face of the aft bulkhead of web member 2 and rotor 3 is adjacent to like this, can realize being removably fixed with of web member 2 and rotor 3 through screw.The front end of web member 2 has been wholely set outward extending annular retaining edge; The annular of web member 2 retaining along on offer be used for bearing seat 1 on the threaded hole of the corresponding one by one setting of mounting hole, during installation shaft bearing 1, with the inside and outside U type groove of bearing seat 1 towards web member 2 moving shaft holders 1; The annulus of bearing seat 1 and the annular retaining edge of web member 2 are adjacent to; The cylindrical shell of bearing seat 1 stretches in the endoporus of web member 2 simultaneously, through screw bearing seat 1 and web member 2 is connected the installation of bearing seat 1 for ease; Offer the through hole that coincide and cooperate with the cylinder body outer wall of bearing seat 1 on the aft bulkhead of web member, this through hole has been the pilot hole of positioning and guiding effect.
In order to guarantee the precision of bearing seat 1, the internal diameter of web member 2 makes the inside and outside U type groove of bearing seat 1 all inboard at the barrel of web member 2 by envelope greater than the external diameter of the outer U type groove of bearing seat 1 like this.
In the foregoing description; Web member 2 is a tubular structure; The connecting portion that the aft bulkhead of web member 2 extends for the fixed part that is connected with rotor 3, rotor dorsad 3 that barrel is the fixed part outer rim, in other embodiments, connecting portion also can be the fixed part outer rim evenly arrange a plurality of; The end of each connecting portion be provided with respectively the retaining edge, each the retaining along last all offer with bearing seat on the corresponding threaded hole of mounting hole.
In other embodiments, also can not offer pilot hole on the aft bulkhead of web member, stretch into part as long as guarantee the cylindrical shell that the interior hole depth of web member can hold bearing seat.
In other embodiments, the annular of web member retaining is along also extending internally.
