Described bearing chamber periphery is provided with the spacing block set of ring-type, spacing block set and plastic casing global formation, and described gland opening is fixed on the inboard of spacing block set; Improve the liquid sealing degree of gland.
Described plastic casing inwall is provided with plurality of strengthening ribs, reinforcement and plastic casing global formation, but the whole compressive strength of reinforced plastics housing.
Have the locating convex block that mates with oiliness bearing on the described gland, have the axis hole corresponding with the oiliness bearing through hole on the locating convex block, the concentricity adjustment of gland and bearing is convenient in the setting of locating convex block, more helps its liquid sealing degree.
Beneficial effect of the present invention:
1), the present invention utilizes the method that plastic casing cooperates with bearing arrangement, the solution of more optimizing is provided, the plastic electric machine casing of high-quality can guarantee higher rotating shaft positioning accuracy, the match and regulate performance that spherical oiliness bearing tool is more superior, the shock-absorbing properties of plastic material is improved, reduced the mechanical oscillation and the noise of motor effectively; Avoid because of using metal shell to cause cost height, defective that technology difficulty is big; Simultaneously, also avoid because of selecting for use plastic casing and bearing integral to make, and cause coaxial accuracy low, do not reach the defective that the rotation flexibility ratio of axle requires;
2), the invention is provided with oil storage tank in the bearing chamber of described plastic casing, be provided with lubricant in the oil storage tank.Have sufficient lubricant deposit, make motor keep sufficient lubricating for a long time, make motor have better operational effect and longer useful life, reduce friction.Owing to use plastic material, make the better insulating protection of motor tool, improve its security performance.Plastic material has been adopted in the invention, has the simple and cheap advantage of manufacturing process, has reduced the use of metal material, has alleviated pts wt.The invention can be used recycled plastics material, is easy to realize that material recycles, compliance with environmental protection requirements.
3), plastic electric machine casing substituted the metal electric machine casing, reduced manufacturing cost significantly;
4), by reinforcement being set at the plastic casing inwall, increase after the housing bulk strength, can guarantee further to reduce amount of plastic under the prerequisite of its requirement of strength, and then reduce manufacturing cost;
5), be provided with the spacing block set of ring-type at bearing chamber periphery, spacing block set and plastic casing global formation, described gland opening is fixed on the inboard of spacing block set; Improve the liquid sealing degree of gland; Moreover, be convenient to gland and be installed in the spacing block set scope.
