Abstract
The utility model provides a kind of motor lower bearing layout of mining flame-proof type submersible sand discharging electric pump, belong to flame-proof type electric diving pump field, it comprises lower end cap and the bearing gland of the rotor axis of electric underpart that is arranged on electric pump, in the mounting hole of lower end cap, be disposed with from top to bottom roller bearing and pair of horns contact ball bearing, the mounting hole inner side surface of lower end cap offers groove, O RunddichtringO is installed in groove, and match in the internal diameter side of O RunddichtringO and the external diameter side of angular contact ball bearing; Bearing gland is arranged on angular contact ball bearing top, is connected with lower end cap bolt.At lower end cap mounting hole inner side surface of the present utility model, offer groove, mounting O-shaped seal ring in groove, angular contact ball bearing is arranged in lower end cap mounting hole by O RunddichtringO, O RunddichtringO plays radially auxiliary fixing effect, can effectively solve that bearing clearance for expansion is little, bearing running hot and the bearing damage problem that causes, guarantee bearing reliably working, increase the service life.
Description
Technical field
The utility model relates to a kind of mining flame-proof type submersible sand discharging electric pump, specifically a kind of motor lower bearing layout of mining flame-proof type submersible sand discharging electric pump.
Background technique
In the process of mining, draining is an important problem always.Flame-proof type submersible sand discharging electric pump obtains general application because it is easy to use, but the working life of its bearing is short, rate of fault is high, chase after its reason and be that lift is high, axial force is larger, main shaft bracketed part is long, the decentraction of radial force and workpiece makes spindle swing aggravation, cause motor lower end cap inner bearing load to increase and heating expansion, coordinate tension with motor lower end cap bearing hole inwall, bearing running hot is expanded, bearing prolonged expansion heating run off grease and burn, and have finally reduced bearing working life.
Summary of the invention
Technical assignment of the present utility model is for the deficiencies in the prior art, the bearing damage problem that the bearing heating that solve in electric pump working procedure because axial force is large, main shaft bracketed part is long, the decentraction of radial force and workpiece causes causes, provides a kind of motor lower bearing layout of mining flame-proof type submersible sand discharging electric pump.
The utility model solves the technological scheme that its technical problem adopts:
A kind of motor lower bearing layout of mining flame-proof type submersible sand discharging electric pump, the lower end cap and the bearing gland that comprise the rotor axis of electric underpart that is arranged on electric pump, in the mounting hole of described lower end cap, be disposed with from top to bottom roller bearing and pair of horns contact ball bearing, the mounting hole inner side surface of lower end cap offers groove, O RunddichtringO is installed in groove, and match in the internal diameter side of O RunddichtringO and the external diameter side of angular contact ball bearing; Described bearing gland is arranged on angular contact ball bearing top, is connected with lower end cap bolt.
Described pair of horns contact ball bearing is installed face-to-face.
Between described pair of horns contact ball bearing, be provided with packing ring between angular contact ball bearing and roller bearing.
Described roller bearing below is provided with back-up ring.
Compared with prior art, the beneficial effect producing is the motor lower bearing layout of a kind of mining flame-proof type submersible sand discharging electric pump of the present utility model:
The utility model is simple in structure, it is convenient to implement, mounting hole inner side surface at lower end cap is offered groove, mounting O-shaped seal ring in groove, make angular contact ball bearing by O RunddichtringO, be arranged in the mounting hole of lower end cap, O RunddichtringO plays radially auxiliary fixing effect, can effectively solve that bearing clearance for expansion is little, bearing running hot and the bearing damage problem that causes; The axle center that can guarantee again bearing operation is simultaneously concentric with rotor axis of electric, makes shaft strength even, guarantees bearing reliably working, extends its working life.
