The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Embodiment.
Referring to Fig. 1 to Fig. 3, the multiple tracks dust-proof mechanism that is used for main shaft in the present embodiment comprises main shaft 1, bearing 2, bearing block 3, end cap 4, bearing labyrinth ring 5, end cap dust ring 6 and main shaft dust ring 7, wherein, the head of main shaft 1 is provided with the collet chuck seat of protrusion, bearing 2 is sleeved on outside the main shaft 1, this bearing 2 is fixed in the bearing block 3, end cap 4 is fixed on the bearing block 3, bearing labyrinth ring 5 is sleeved on main shaft 1 outside also and end cap 4 matches, the collet chuck seat matches with end cap 4, end cap dust ring 6 is fixed on the end cap 4, and main shaft dust ring 7 is sleeved on the collet chuck seat, and end cap dust ring 6 and main shaft dust ring 7 match.
Bearing 2 in the present embodiment, end cap 4, bearing labyrinth ring 5, end cap dust ring 6 and main shaft dust ring 7 are arranged in order from left to right, as shown in Figure 2.Bearing labyrinth ring 5 is sleeved on the main shaft 1 by interference fit, bearing labyrinth ring 5 is provided with the first dustproof section 8 and the second dustproof section 9, the axial height of the second dustproof section 9 is higher than the axial height of the first dustproof section 8, be provided with the dustproof section 10 of end cap on the end cap 4, the dustproof section 10 of this end cap is installed between the first dustproof section 8 and the second dustproof section 9, keep very little gap between the dustproof section 10 of end cap and the first dustproof section 8, also keep very little gap between the dustproof section 10 of end cap and the second dustproof section 9, the groove between the first dustproof section 8 and the second dustproof section 9 is called labyrinth dustproof groove 11.
Keep very little gap between the bottom land of the dustproof section 10 of the end cap in the present embodiment and labyrinth dustproof groove 11, also be provided with end cap dustproof groove 12 on the end cap 4, the first dustproof section 8 is installed in the end cap dustproof groove 12, little matched in clearance between the bottom land of the first dustproof section 8 tops and end cap dustproof groove 12, the inside and outside both sides of two cell walls of end cap dustproof groove 12 and the first dustproof section 8 are little matched in clearance respectively, the outside of the dustproof section 10 of end cap and the inboard little matched in clearance of the first dustproof section 8, the inboard of the dustproof section 10 of end cap and the little matched in clearance in the outside of the second dustproof section 9.
Be adjustable little matched in clearance between the collet chuck seat that end cap dust ring 6 in the present embodiment and main shaft 1 head protrude, main shaft dust ring 7 is fixedly mounted on by interference fit on the collet chuck seat of main shaft 1 head protrusion, little matched in clearance between main shaft dust ring 7 and the end cap dust ring 6.
Multiple tracks dust-proof mechanism in the present embodiment is mainly used in the main shaft of lathe, when using, rotation by main shaft 1 drives main shaft dust ring 7 and rotates, because little matched in clearance between main shaft dust ring 7 and the end cap dust ring 6, so that chip or cutting fluid are difficult to enter in the gap between main shaft dust ring 7 and the end cap dust ring 6, even a small amount of chip or cutting fluid enter in this gap, under the effect of centrifugal force, also this chip or cutting fluid can be thrown away.
Owing to being adjustable little matched in clearance between end cap dust ring 6 and the collet chuck seat, so that the user can regulate the gap between end cap dust ring 6 and the collet chuck seat, can regulate this gap according to the quality of main shaft 1 balance, when main shaft 1 balance is fine, vibrations are very little in the rotation process, thereby so that this gap can suitably be turned down, prevent that chip or cutting fluid from entering in this gap; If the balance of main shaft 1 is not fine, perhaps make the vibrations that produce in main shaft 1 rotation process comparatively strong owing to service time is long, just this gap suitably can be tuned up, prevent end cap dust ring 6 and touch and the situation of accelerated wear test mutually with the collet chuck seat.Because the collet chuck seat is also rotating, thus when chip or cutting fluid enter in the gap, owing to centrifugal action so that chip or cutting fluid are close to the inboard of end cap dust ring 6.
Main shaft 1 in the present embodiment rotates, so that the first dustproof section 8 and the second dustproof section 9 also rotate, even so that chip or cutting fluid when entering in the gap between first dustproof section 8 outsides and the end cap dustproof groove 12, this chip or cutting fluid also can be thrown away and be affixed on the cell wall of end cap dustproof groove 12 by centrifugal force under the effect of centrifugal force.In like manner, when chip or cutting fluid enter gap between the first dustproof section 8 inboards and the dustproof section of end cap 10 outsides, also can be owing to the effect of centrifugal force so that chip or cutting fluid be affixed on the inboard of the first dustproof section 8.In like manner, when chip or cutting fluid entered the gap in inboard and the second dustproof section 9 outsides of the dustproof section of end cap 10, chip or cutting fluid also can be affixed on the prevent dust inboard of section 10 of end cap.Above each gap has guaranteed that effectively chip or cutting fluid can not enter into main shaft inside, thereby has improved the service life of main shaft.
The little matched in clearance of mentioning in the utility model refers to, the gap between two parts that match is very little and cooperatively interact.The inboard of the first dustproof section 8 that mentions in the utility model, the second dustproof section 9 and the dustproof section 10 of end cap refers to the side towards main shaft 1, and the outside of the first dustproof section 8, the second dustproof section 9 and the dustproof section 10 of end cap refers to a dorsad side of main shaft 1.
In addition, need to prove, the specific embodiment described in this specification, the shape of its parts and components, institute's title of being named etc. can be different, and the above content described in this specification only is to the explanation of the utility model structure example.Allly conceive equivalence variation or the simple change that described structure, feature and principle are done according to the utility model patent, be included in the protection domain of the utility model patent.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount this scope as defined in the claims, all should belong to protection domain of the present utility model.
