Abstract
The utility model relates to a bearing bush and bearing sleeve composite structure for a submersible motor, which consists of a head-and-seat, a bearing bush, a bearing sleeve, a bond and a shaft, wherein the bearing sleeve is arranged on the shaft, the bond is used for preventing the rotation of the bearing sleeve, the bearing bush is arranged on the head-and-seat, and a pair of bearing structures of the bearing bush and the bearing sleeve can be formed; the bearing bush and the bearing sleeve are provided with an oil through hole or an oil through groove which can facilitate heat dissipation of the bearings and an oil film can be formed; an oil hole is arranged in the centre of the shaft, an oil through hole is arranged in the radial direction, and a circulation loop is formed between the bearing sleeve and the bearing bush. The bearing bush and bearing sleeve structure for the submersible motor is also applicable to the centralizer bearing of the submersible motor.
Description
(1) technical field
The utility model relates to a kind of submersible electric machine with oil axial sleeve of bushing combining structure, particularly a kind of combining structure that between axle and bearing shell, installs axle sleeve additional.
(2) background technology:
At present, bearing shell that submersible electric machine with oil both domestic and external uses and directly friction of axle need repairing after the wearing and tearing; But the maintenance intermediate bushing causes the wearing and tearing again of axle even scraps with poor slightly just being easy to of the concentricity of axle; The method that solves need more renew axle exactly, waste very greatly, also requires axle Surface Machining precision height in addition; But can't change the better material of resistance to wear, therefore this structure has in use received certain limitation.
(3) utility model content:
The purpose of the utility model is to above-mentioned shortcoming, and the novel combination structure that installs axle sleeve between a kind of axle and the bearing shell additional is provided, and reaches and can protect axle to be convenient to the double effects that keeps in repair, changes again.
The technical scheme of the utility model: a kind of bearing shell and axle sleeve combining structure is characterized in that it is made up of head and seat, bearing shell, axle sleeve, key, five part.
Above-mentioned said axle sleeve 3 is installed on the axle 5, prevents that through key 4 its axle sleeve 3 from rotating, and bearing shell 2 is installed on head and the seat 1, constitutes the pair of bearings structure of bearing shell 2 and axle sleeve 3 like this.
Above-mentioned said bearing shell 2 had oil groove 8 or ring shaped slot is beneficial to the bearing heat radiation, and forms oil film.
There is oilhole at above-mentioned said axle 5 centers, oil-through hole 7 is radially arranged, and constitute a circulation circuit between axle sleeve 3 and the bearing shell 2.
Above-mentioned said axle sleeve 3 adopts wear-resistant metal material, and bearing shell 2 adopts wear-resisting metal or nonmetallic materials, like copper alloy or composite material.
Above-mentioned said submersible electric machine with oil bearing shell and axle sleeve structure also can be applicable in the submersible electric machine with oil alignment bearing.
The superiority of the utility model is: (1) has increased axle sleeve, is convenient to maintain and replace; (2) bearing shell does not directly rub with axle, has protected axle; (3) bearing shell had oil groove, had improved lubricating ability; (4) can use the bearing shell and the axle sleeve of different materials, improve radially ability to bear.
(4) description of drawings:
Fig. 1 is the structural representation of the related a kind of submersible electric machine with oil axial sleeve of bushing combining structure of the utility model;
Fig. 2 is the submersible electric machine with oil axle sleeve structure sketch map in the related a kind of submersible electric machine with oil axial sleeve of bushing combining structure of the utility model;
Fig. 3 is the submersible electric machine with oil bearing shell structural representation in the related a kind of submersible electric machine with oil axial sleeve of bushing combining structure of the utility model.
Wherein: 1 is head and seat, and 2 is bearing shell, and 3 is axle sleeve, and 4 is key, and 5 is axle, and 6 is keyway, and 7 is oil-through hole, and 8 was oil groove.
(5) embodiment:
Embodiment: a kind of submersible electric machine with oil axial sleeve of bushing combining structure (see figure 1) is characterized in that it is made up of head and seat, bearing shell, axle sleeve, key, five part; Wherein, oil groove 8 was arranged on the bearing shell (see figure 3), oil-through hole 7, keyway 6 were arranged on the axle sleeve (see figure 2); Be installed in axle sleeve 3 on the axle 5 and make it fixing with key 4, bearing shell 2 is installed on head and the seat 1, form reasonably, oil-through hole is arranged on axle sleeve 3, bearing shell 2 or cross oil groove, be beneficial to bearing heat radiation and lubricated the mill supplementary bearing.
Claims (1)
1. submersible electric machine with oil axial sleeve of bushing combining structure, its basic structure is made up of head and seat (1), bearing shell (2), axle sleeve (3), key (4), axle (5) five parts, it is characterized in that axle sleeve (3) is installed on spool (5); Prevent its rotation through key (4); Bearing shell (2) is installed on head and the seat (1), constitutes the pair of bearings structure of bearing shell (2) and axle sleeve (3) like this, and there is oilhole at axle (5) center; Oil-through hole (7) is radially arranged; And constitute a circulation circuit between axle sleeve (3) and the bearing shell (2), bearing shell (2) had oil groove (8) or ring shaped slot is beneficial to the bearing heat radiation, and forms oil film.
