Abstract
A motor bearing composite structure special for a self-priming pump comprises a non-drive end of a motor shaft, a deep groove ball bearing and a round nut, wherein the deep groove ball bearing, a gasket, an angular contact thrust bearing, a retaining gasket and the round nut are sequentially arranged on the non-drive end of the motor shaft from bottom to top. The motor bearing composite structure special for the self-priming pump is reasonable in structure, the bearing at the non-drive end of a motor cannot burn out because of a high temperature, the service life of the motor is prolonged, and repair rate is lowered.
Description
Technical field:
The utility model relates to industrial pump, relates in particular to a kind of self-priming pump motor special bearing combined structure.
Background technique:
The self-priming pump necessary electromotor is originally the Y2 serial motors of direct employing, because motor and self-priming pump are vertical installations, and the drive end impeller of direct-connected water pump vertically downward, as long as self-priming pump is in moment of starting, be exactly the process of Absorb Water, make the main shaft of impeller and motor have the axial force that makes progress more greatly; When water pump works; motor again impeller is downward; a kind of downward axial force with discharging; the axial force direction that produces for electric machine main shaft in this conventional working procedure is unfixed; be easy to cause the non-driven-end bearing temperature of motor very high; although the motor band is not shut down injection-discharge oil device; but the notes oil extraction cycle is very short; in case safeguard and not in placely just easily burn out a bearing; when motor bearings breaks down; motor just looks like with very large load stall, and the electric current straight line rises and certainly will cause that the motor winding is overheated and also burn out.Through repeatedly use scene and investigation and the tracking of process operating mode, the bearing of motor anti-drive end is compared the axial force impact of bearing with drive end relatively large, also easy burn-out.
Summary of the invention:
The purpose of this utility model provides a kind of self-priming pump motor special bearing combined structure, and the motor non-driven-end bearing is no longer burnt out because temperature is high.
The utility model is achieved in that a kind of self-priming pump motor special bearing combined structure, comprise motor shaft anti-drive end, deep groove ball bearing, round nut, it is characterized in that: described motor shaft anti-drive end is disposed with deep groove ball bearing, pad, angular contact thrust bearing, stopping shim and round nut from below to up.
Spacer thickness described in the utility model is 0.15mm, and it is nonmetallic material that pad adopts material.
The utility model is rational in infrastructure, and the motor non-driven-end bearing is burnt out because temperature is high, has improved the working life of motor, has reduced repair rate.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Among the figure 1, deep groove ball bearing, 2, angular contact thrust bearing, 3, stopping shim, 4, round nut, 5, the motor shaft anti-drive end, 6, pad.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
With reference to accompanying drawing, a kind of self-priming pump motor special bearing combined structure, comprise motor shaft anti-drive end 5, deep groove ball bearing 1, round nut 4, it is characterized in that: described motor shaft anti-drive end 5 is disposed with deep groove ball bearing 1, pad 6, angular contact thrust bearing 2, stopping shim 3 and round nut 4 from below to up.Described pad 6 thickness are 0.15mm, and it is nonmetallic material that pad 6 adopts material.During implementation, change the anti-drive end deep groove ball bearing of motor into the duplex bearing composite structure by original single ball bearing: namely deep groove ball bearing adds the duplex bearing composite structure of an angular contact thrust bearing, wherein angular contact thrust bearing is in the outer end, large mouthful of thrust angle is downward, has born motor band impeller and has started the larger thrust that makes progress when absorbing water; Deep groove ball bearing is in the angular contact thrust bearing the inside, motor has downward thrust when working after starting, but smaller than the power that makes progress, the deep groove ball bearing of installation is met the demands, and lubricating grease is unlikely to get rid of electric leakage machine inner chamber when having guaranteed simultaneously also that the angular contact thrust bearing heavy caliber is downward.The bearing of motor bears unfixed axial force up and down, easy frictional heating, for increasing the expansion space of bearing heating, between two bearings, establish and put the 0.15mm nonmetallic material, such structure is passed through verification experimental verification, bearing temperature only has 50-60 ℃, has improved original bearing temperature and has reached 90-95 ℃ upper limit (UL) and burn out.Enough satisfy the requirement of applying working condition, guaranteed safe and reliable operation.Such bearing combined structure is followed the tracks of and supervision and check through on-the-spot the use, and effect is fine, although disposable input cost improves, makes the bearing of motor burn out repair rate and greatly reduces, and has improved simultaneously the prestige that the self-priming pump motor special uses in the industry.
