Abstract
The utility model provides a kind of motor lower bearing layout of 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 being arranged on electric pump, in the mounting hole of described lower end cap, gap is provided with deep groove ball bearing and pair of horns contact ball bearing successively from top to bottom, the mounting hole inner side surface of lower end cap offers groove, O RunddichtringO is installed in groove, and match with the external diameter side of deep groove ball bearing in the internal diameter side of O RunddichtringO; Described bearing gland is arranged on above angular contact ball bearing, is connected with lower end cap bolt.Deep groove ball bearing of the present utility model coordinates with O RunddichtringO and is arranged in the mounting hole of lower end cap, O RunddichtringO can eliminate bearing by thermogenetic swell increment, effective solution bearing clearance for expansion is little, bearing running hot and cause bearing damage problem, make shaft strength even simultaneously, ensure the reliably working of bearing, extend its working life.
Description
Technical field
The flame-proof type submersible sand discharging electric pump that the utility model uses under relating to a kind of mine, specifically a kind of motor lower bearing layout of 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 aggravate, motor lower end cap inner bearing load is caused to increase and fever expansion, tension is coordinated with motor lower end cap bearing hole inwall, bearing running hot is expanded, bearing prolonged expansion heating makes grease run off and burn, eventually reduces bearing working life.
Summary of the invention
Technical assignment of the present utility model is for the deficiencies in the prior art, because of the bearing damage problem that the bearing heating that axial force is large, the decentraction of main shaft bracketed part length, radial force and workpiece causes causes in solution electric pump working procedure, provide a kind of motor lower bearing layout of 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 flame-proof type submersible sand discharging electric pump, comprise lower end cap and the bearing gland of the rotor axis of electric underpart being arranged on electric pump, in the mounting hole of described lower end cap, gap is provided with deep groove ball bearing and pair of horns contact ball bearing successively from top to bottom, the mounting hole inner side surface of lower end cap offers groove, O RunddichtringO is installed in groove, and match with the external diameter side of deep groove ball bearing in the internal diameter side of O RunddichtringO; Described bearing gland is arranged on above angular contact ball bearing, is connected with lower end cap bolt.
Described pair of horns contact ball bearing is installed in series.
Packing ring is provided with between described angular contact ball bearing and deep groove ball bearing.
The below of described deep groove ball bearing is provided with back-up ring.
Compared with prior art, the beneficial effect produced is the motor lower bearing layout of a kind of flame-proof type submersible sand discharging electric pump of the present utility model:
The utility model structure is simple, it is convenient to implement, deep groove ball bearing coordinates with O RunddichtringO and is arranged in the mounting hole of lower end cap, O RunddichtringO plays radial auxiliary fixing effect, can also eliminate bearing by thermogenetic swell increment, effectively solves that bearing clearance for expansion is little, bearing running hot and cause bearing damage problem, ensure that the axle center that bearing runs is concentric with rotor axis of electric simultaneously, make shaft strength even, ensure the reliably working of bearing, extend its working life.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
In figure, 1, bearing gland, 2, angular contact ball bearing, 3, O RunddichtringO, 4, deep groove ball bearing, 5, rotor axis of electric, 6, packing ring, 7, lower end cap, 8, bolt, 9, back-up ring.
Embodiment
Be described in detail below below in conjunction with the motor lower bearing layout of accompanying drawing to a kind of flame-proof type submersible sand discharging electric pump of the present utility model.
As shown in Figure 1, the motor lower bearing layout of a kind of flame-proof type submersible sand discharging electric pump of the present utility model, its structure comprises lower end cap 7 and the bearing gland 1 of rotor axis of electric 5 underpart being arranged on electric pump, in the mounting hole of described lower end cap 7, gap is provided with deep groove ball bearing 4 and pair of horns contact ball bearing 2 successively from top to bottom, the mounting hole inner side surface of lower end cap 7 offers groove, O RunddichtringO 3 is installed in groove, and match with the external diameter side of deep groove ball bearing 4 in the internal diameter side of O RunddichtringO 3; Described bearing gland 1 is arranged on above angular contact ball bearing 2, is connected with lower end cap 7 bolt 8; Detailed, described pair of horns contact ball bearing 2 is installed in series, and is provided with packing ring 6 between described angular contact ball bearing 2 and deep groove ball bearing 4, and the below of deep groove ball bearing 4 is also provided with back-up ring 9.
Its processing and fabricating of motor lower bearing layout of a kind of flame-proof type submersible sand discharging electric pump of the present utility model is simple and convenient, processing and fabricating shown in by specification accompanying drawing.
Except the technical characteristics described in specification, be the known technology of those skilled in the art.
