Abstract
A method for sealing small-and-medium-size vertical motor bearing components is characterized in that a bent circuit and a felt collar are combined for sealing, namely a turned groove is additionally formed in a bearing sleeve, and an oil seal cover provided with a groove (the oil seal cover is fixed to a rotating shaft and rotates along with the rotating shaft) is used for replacing a bearing cap in a traditional sealing method. When a sealing structure is designed, the sealing reliability is enhanced by selecting the size of a gap reasonably. According to the method for sealing the small-and-medium-size vertical motor bearing components, no part is added, assembly is quite convenient, and the effect is good proved by actual operation.
Description
Technical field
The present invention relates to encapsulating method, especially a kind of encapsulating method of middle-size and small-size vertical machine parts of bearings.
Background technology
Middle and small motor is generally used rolling bearing, and in order to prevent that lubricating oil (grease) from oozing out and preventing the extraneous harmful substance intrusion such as dust, foul, moisture bearing in bearing chamber, service-strong sealing device is necessary.In addition, for fear of lubricated (fat), get rid of into winding, the normal operation that guarantees motor unshakable in one's determination, the reliability of sealing is just more important.
On minitype vertical type motor, generally use a simple bearing cap, several oil grooves on endoporus car, adopt cast slit seal or the sealing of felt collar formula also just much of that.For slightly larger medium-sized vertical type motor, such sealing is just reliable not.But the sealing device that for this reason designs a set of complexity is uneconomic.
Summary of the invention
In order to solve the deficiency of above-mentioned motor bearings parts conventional seals method, the invention provides a kind of encapsulating method of middle-size and small-size vertical machine parts of bearings, the method is not only simple in structure, and sealing is reliable.
The technical solution adopted for the present invention to solve the technical problems is: adopt Qu Lu and felt collar to combine sealing, on bearing holder (housing, cover), increase rut groove, with the oil sealing cap (this lid is fixed in rotating shaft and rotates with the axis) of a with groove, replace the bearing cap in conventional seals.
The invention has the beneficial effects as follows: sealing method does not increase part, assemble also very convenient, through actual motion, respond well.
Accompanying drawing explanation
Fig. 1 is the sealed structure chart that motor bearings parts adopt.
In figure 1, bearing holder (housing, cover), 2, oil sealing cap.
Embodiment
In hermetically-sealed construction, at the upper rut groove that increases of bearing holder (housing, cover) (1), with the oil sealing cap (2) (this lid is fixed in rotating shaft and rotates with the axis) of a with groove, replace original bearing cap as shown in Figure 1.
During design labyrinth seal, first consider the overall size of parts of bearings, should consider sealing effectiveness and easy to assembly in addition.Sealing reliability depends on bent road level and gap length.Concrete bent road gap length sees table (in table, d is the bearing diameter indicating in Fig. 1, and e and f are the labyrinth seal gap indicating in Fig. 1):
| d | 10-45 | 50-80 | 85-110 | 120-180 |
| e | 0.2 | 0.3 | 0.4 | 0.5 |
| f | ? | 5e | ? | ? |
Should guarantee to extend because being heated at axle or the impact of other factors under, rotation and not friction of fixing seals, putting and selecting as far as possible little gap before this.For example,, when for spherical bearing, for preventing that crooked generation of axle from interfering the ，Gu gap should be not too small.The main shaft of vertical machine is heated and can extends, so should not adopt axial labyrinth.In addition, in order to strengthen sealing effectiveness, in assembling gap, Qian，Qu road, should fill up lubricating grease.
Such scheme industry technical staff can realize by industry technology means.
