Abstract
The invention belongs to the technical field of motor and electric pump components and discloses a spherical iron shaft sleeve. The spherical iron shaft sleeve comprises a shaft sleeve body. The shaft sleeve body comprises a reinforcing rib machining face, a bearing hole, grooves, an inner bearing installation portion, a reinforcing rib for installation, reinforcing ribs and a bolt hole end face. The outer side of the bearing hole is connected with the inner bearing installation portion. The bolt hole end face is arranged on the outer side of the inner bearing installation portion. The reinforcing rib machining face is arranged on one side of the bolt hole end face. One side of the reinforcing rib machining face is connected with the reinforcing ribs. One side of each reinforcing rib is connected with the corresponding groove. An original cast iron shaft sleeve is replaced with the shaft sleeve made of spherical iron, the spherical iron shaft sleeve is reasonable in structure and good in ductility and impact resistance, the service life of the spherical iron shaft sleeve is prolonged, and the problems that a shaft sleeve is incapable of bearing loads, easy to break, frequent in replacement and short in service life and affects utilization of the shaft sleeve are solved; and meanwhile, the reinforcing ribs are designed, shaft sleeve stability is enhanced, deformation is not likely to happen, and the use effect is improved.
Description
Technical field
The present invention relates to a kind of motor electric pump parts, be specifically related to a kind of magnesium iron axle sleeve, belong to motor electric pump component technology field.
Background technique
The heavy engineering such as excavator, bulldozer machinery, its target mostly is earth, sandstone.Such machinery has the coupling shaft that many places are combined by rotating shaft and axle sleeve, and at present, existing axle sleeve many employings cast iron, this cast iron is not corrosion-resistant, and especially axle sleeve not load-bearing, easy-rupturing, replacing are frequent, and working life is short, the problem that affect axle sleeve use itself.Cause shorten working life, cost of production increases.In sum, original cast iron axle sleeve is replaced to the axle sleeve made with magnesium iron by the present invention, and its rational structure more has good ductility and impact resistance, its working life is extended, and solves axle sleeve not load-bearing, easy-rupturing, replacing are frequent, working life is short, affect the problem that axle sleeve itself uses, meanwhile, devise stiffening rib, enhance axle sleeve steadiness, not yielding, improve its using effect, for this reason, we propose a kind of magnesium iron axle sleeve.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, a kind of magnesium iron axle sleeve is provided, original cast iron axle sleeve is replaced to the axle sleeve made with magnesium iron, its rational structure more has good ductility and impact resistance, its working life is extended, solve axle sleeve not load-bearing, easy-rupturing, replacing are frequent, working life is short, affect the problem that axle sleeve itself uses, simultaneously, devise stiffening rib, enhance axle sleeve steadiness, not yielding, improve its using effect, effectively can solve the problem in background technique.
In order to solve the problems of the technologies described above, the invention provides following technological scheme:
The invention provides a kind of magnesium iron axle sleeve, comprise sleeve body, described sleeve body comprises stiffening rib working surface, bearing hole, groove, inner bearing installation place, installation stiffening rib, stiffening rib and bolt hole end face, be connected with inner bearing installation place outside described bearing hole, bolt hole end face is provided with outside described inner bearing installation place, described bolt hole end face side is provided with stiffening rib working surface, and described stiffening rib working surface side is connected with stiffening rib, and described stiffening rib side is connected with groove.
As a preferred technical solution of the present invention, described stiffening rib working surface, bearing hole, groove, inner bearing installation place, installation stiffening rib, stiffening rib and bolt hole end face are through normalized treatment.
As a preferred technical solution of the present invention, uneven place is not contained through chipping process in described bearing hole and inner bearing installation place.
As a preferred technical solution of the present invention, described sleeve body internal surface is sprayed with rust proof paint.
As a preferred technical solution of the present invention, described sleeve body carry out 10MPa water pressure resistance test five minutes non-leakage.
The beneficial effect that the present invention reaches is: a kind of magnesium iron axle sleeve, original cast iron axle sleeve is replaced to the axle sleeve made with magnesium iron, its rational structure more has good ductility and impact resistance, its working life is extended, the problem solve axle sleeve not load-bearing, easy-rupturing, replacing are frequent, working life is short, affect axle sleeve use itself, simultaneously, devise stiffening rib, enhance axle sleeve steadiness, not yielding, improve its using effect.
