Description
Technical field
This utility model is related to a kind of part of high-speed electric main shaft, more particularly to a kind of high-speed main spindle dust cover.
Background technology
Main shaft is lathe core component, is extensively applied with the rise of High-speed machining.In the nothing such as woodworking machinery and pcb board
A large amount of dust can be produced in the processing of cutting fluid field, to prevent dust from entering inside raceway, bearing life and main shaft is affected
Precision, it will usually add sealing ring in the end of main shaft.Because the speed of mainshaft is high, conventional seals circle produces heat in high-speed rotation
Amount, affects sealing property, even burns out main shaft when serious, it is impossible to meet use requirement.
The content of the invention
Technical problem to be solved in the utility model is, there is provided a kind of high-speed main spindle dust cover, can prevent dust
Into inside main shaft, even if contacting also will not produce hyperpyrexia with shaft core, it is ensured that the functional reliability of main shaft.
In order to solve above-mentioned technical problem, this utility model provides a kind of high-speed main spindle dust cover, and it is located at a high speed
The end of main shaft, for preventing dust from entering in main shaft, including cover plate and composite cover, the cover plate central authorities are provided with circular hole, described
Composite cover is annular slice, and it is located in the circular hole.
Used as the improvement of such scheme, the side wall of the circular hole is provided with cannelure, and the composite cover snaps in the cannelure
In and radially extend to center of circular hole.
Used as the improvement of such scheme, the composite cover includes annular iron plate, the both sides of the annular iron plate and at least
Bread is covered with plastic layer.
Used as the improvement of such scheme, the plastic layer is located at the thickness at annular iron plate both sides position more than annular iron plate certainly
Body thickness.
Used as the improvement of such scheme, the high-speed main spindle also includes rotor and shaft core, sets between the rotor and shaft core
There is lower bearing, the lower bearing lower section is provided with bearing cap, and the high-speed main spindle dust cover is located at bearing cap lower section.
Implement this utility model, have the advantages that：
By arranging main shaft cover plate in the end of high-speed main spindle, it includes cover plate and composite cover, the lid to this utility model
Plate central authorities are provided with circular hole, and the composite cover is annular slice, and it is located in the circular hole, are prevented from dust and enter in main shaft
Portion, even if contacting also will not produce hyperpyrexia with shaft core, it is ensured that the functional reliability of main shaft.
Description of the drawings
Fig. 1 is a kind of structural representation of high-speed main spindle dust cover of this utility model；
Fig. 2 is the combining structure schematic diagram of cover plate of the present utility model and composite cover；
Fig. 3 is the combining structure schematic diagram at another visual angle of cover plate of the present utility model and composite cover；
Fig. 4 is the structural representation of composite cover of the present utility model.
Specific embodiment
It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer
Type is described in further detail.Only this statement, this utility model occur in the text or will appear from upper and lower, left and right, it is front,
Afterwards, the orientation such as inside and outside word, only on the basis of accompanying drawing of the present utility model, it is not to concrete restriction of the present utility model.
As Figure 1-Figure 4, this utility model embodiment provides a kind of dust-proof main shaft cover plate of high-speed main spindle, and it is located at height
The end of fast main shaft, for preventing dust from entering in main shaft, including cover plate 1 and composite cover 2, the central authorities of the cover plate 1 are provided with circular hole
11, the composite cover 2 is annular slice, and it is located in the circular hole 11.Wherein, the side wall of the circular hole 11 is provided with cannelure
12, the composite cover 2 is snapped in the cannelure 12 and radially extended to circular hole 11.
Preferably, the composite cover 2 includes annular iron plate 21, and the both sides of the annular iron plate 21 and at least one side are coated with
Plastic layer 22.Wherein, the plastic layer 22 is located at the thickness at the annular both sides position of iron plate 21 more than the annular its thickness of iron plate 21.
It should be noted that the annular iron plate 21 ensure that the rigidity of composite cover 2 so as to be difficult under complicated operating mode
Deform.The plastic layer 22 is used to provide protection for annular iron plate 21, when contacting with composite cover 2 the shaft core short time, modeling
The bed of material 22 plays cushioning effect, the coefficient of friction of composite cover 2 and shaft core is reduced, so as to reduce caloric value.When shaft core and composite cover 2
Time of contact it is longer when, plastic layer 22 will be worn, and so as to prevent the long-time friction of shaft core and composite cover 2, protect main shaft.
Preferably, the high-speed main spindle also includes rotor 3 and shaft core 4, and between the rotor 3 and shaft core 4 lower bearing is provided with
5, the lower section of the lower bearing 5 is provided with bearing cap 6, and the high-speed main spindle dust cover 1 is located at the lower section of bearing cap 6.
This utility model in the end of high-speed main spindle by arranging main shaft cover plate 1, and it includes cover plate 1 and composite cover 2, described
The central authorities of cover plate 1 are provided with circular hole 11, and the composite cover 2 is annular slice, and it is located in the circular hole 11, are prevented from dust entrance
Inside main shaft, even if contact will not also produce hyperpyrexia with shaft core 4, it is ensured that the functional reliability of main shaft.
Above disclosed is only a kind of preferred embodiment of this utility model, can not limit this practicality with this certainly
New interest field, therefore the equivalent variations made according to this utility model claim, still belong to what this utility model was covered
Scope.
