Abstract
The invention discloses a shaft coupler used for a vertical pump with a long distance between shafts. The shaft coupler comprises a motor end half shaft section (1), a middle connecting section (2) and a shaft end half shaft section (3), wherein each of the motor shaft half shaft section (1) and the shaft end half shaft section (3) comprises a left half section, a right half section, a diaphragm assembly and a protective cover, which respectively form a classical diaphragm shaft coupler structure; a plane thrust bearing (35) is arranged between the left half section (31) and the right half section (32) of the shaft end half shaft section (3), so that plane thrust bearing (35) support fit is formed between the left half section (31) and the right half section (32); the left connecting section (21) and the right connecting section (23) of the middle connecting section (2) are respectively in fit joint with the motor end half shaft section (1) and the shaft end half shaft section (3) by adopting inner and outer splines. The plane thrust bearing (35) is arranged in the shaft end half shaft section (3) for bearing weight of the middle connecting section (2), so that pressure effect of the diaphragm component on (33) is eliminated, work in a normal stress state is ensured, and the service life is prolonged.
Description
Technical field
What the present invention relates to is coupling, particularly a kind of coupling for the pump drive of major axis interval vertical.
Background technique
Vertical pump motor and pump shaft generally adopt rigid coupling to be connected, along with diaphragm coupling is in extensive use in recent years, increasing producer hope diaphragm coupling carrys out the rigid coupling of the structural types such as alternative clamping coupling, but the current this alternative structure being only limitted to minor axis spacing.And the coupling of vertical pump for major axis spacing, because coupling is long, weight is large, poor stability, be easy to damage, working life is short.
Summary of the invention
The object of the invention is easily to damage for the coupling of prior art for major axis interval vertical pump, the problem that working life is short, a kind of major axis interval vertical pump diaphragm type coupler of long service life is provided.
The present invention is made up of motor side half hub section 1, middle connecting joint 2, axle head half hub section 3;
Motor side half hub section 1 is made up of left half-section 11, right half-section 12, diaphragm unit 13 and protective housing 14, and it forms typical diaphragm coupling structure;
Middle connecting joint 2 coordinates docking to connect and compose by flange plate seam by left connecting joint 21, middle connecting joint 22, right connecting joint 23 mutually;
Axle head half hub section 3 is made up of left half-section 31, right half-section 32, diaphragm unit 33 and protective housing, it forms typical diaphragm coupling structure, left half-section 31 offers seam 34, seam 34 is provided with plain thrust bearing 35, right half-section 32 is fixedly connected with and is provided with bearing (ball) cover 36 and coordinates with plain thrust bearing 35, make to form plain thrust bearing 35 bearing engagement between left half-section 31 and right half-section 32;
The right half-section 12 of motor side half hub section 1 adopts inside and outside spline fitted to be connected with the left connecting joint 21 of middle connecting joint 2; The left half-section 31 of axle head half hub section 3 adopts inside and outside spline fitted to be connected with the right connecting joint 23 of middle connecting joint 2.
The present invention adopts segmentation structure, adopts rational tolerance fit between all parts, convenient processing, assembling, and can ensure its required precision.
The present invention arranges plain thrust bearing 35 to carry the weight of middle connecting joint 2 in axle head half hub section 3, carry out spacing to middle connecting joint 2 string quantity of motion, the pressure effect that in the middle of eliminating, connecting joint 2 weight produces diaphragm unit 33 in axle head half hub section 3 simultaneously, ensure that axle head half hub section 3 diaphragm unit 33 is in normal stress to work, increase the service life;
And the diaphragm unit 13 of motor side half hub section 1 does not bear the effect of middle connecting joint 2 weight pulling force, the diaphragm unit 13 of motor side half hub section 1 is in normal stress and works, and increases the service life.
The present invention, owing to being provided with plain thrust bearing 35 in axle head half hub section 3, also can limit the swing (angular displacement) that middle connecting joint 2 produces in rotation, uses coupling run stability to improve.
Accompanying drawing explanation
fig. 1 is embodiment of the present invention structural representation.
