Abstract
A novel bearing oil sealing structure relates to the improvement of a mechanical structure. In the prior art, the sealing performance is bad. In the utility model, a fuel-displaced hole is opened on a bearing end cover, a sealing groove is opened between the bearing end cover and a locking nut, a sealing strip is arranged in the sealing groove, the sealing strip is pressed between the bearing end cover and the locking nut by a pressing mechanism, and the pressing mechanism can be detachably connected at the outside of the bearing end cover. By employing the detachable and pressure-adjustable pressing mechanism with the sealing strip, the adjustment replacing in time on site can be convenient, the oil sealing performance of the bearing mechanism is improved, the bulk polytetrafluoroethylene sealing strip has low cost and reliable sealing performance.
Description
Technical field
The utility model relates to the improvement of mechanical structure, specifically is the oil seal structure of improveing in a kind of bearing.
Background technique
Gear mechanism is widely used in various machineries, and it mainly comprises axle 1, bearing 2 and bearing support 3 three parts.In actual use, rotate more suitable cunning mutually in order to make each parts, need be between parts lubricating oil filling.Therefore, at the injection and the sealing of lubricant oil, need in gear mechanism, increase ad hoc structure.
Existing bearing mechanism all is provided with filler opening and oil outlet at the bearing support relative position, this structure in use, owing to the pressure reason, the bearing that lubricant oil may not arrive two ends just is discharged from, lubrication effect is not good.
In addition, also be provided with oil seal structure in the existing bearing, as shown in Figure 1, outside framework oil seal 6 be housed on the bearing (ball) cover 4, spill from the space between bearing (ball) cover and the locking nut 7 to prevent oil.
But the outside framework oil seal of this oil seal structure can wear and tear because of repeatedly rubbing after the long operating time, caused sealability bad, produced oil leakage phenomenon.Constant because of its replacing, cause bearing support biend greasy dirt continuous.
The model utility content
In order to solve the above-mentioned problems in the prior art, the utility model provides a kind of novel bearing oil seal structure, reaches the purpose that guarantees lubrication effect, is easy to change, guarantee sealability by improving structure.
For this reason, the utility model is by the following technical solutions:
The novel bearing oil seal structure, comprise axle, bearing support and be located at bearing between the two, the distolateral bearing (ball) cover that is fixed with of bearing support, bearing (ball) cover and between centers are provided with the locking nut of stationary axle position, axle, bearing support, form an oily receiving cavity between bearing (ball) cover and locking nut and the bearing, it is characterized in that: offer oil outlet on the described bearing (ball) cover, offer seal groove between described bearing (ball) cover and the locking nut, be provided with Stamping Steel Ribbon in the seal groove, the sealing bar is pressed between bearing (ball) cover and the locking nut by a hold-down mechanism, and described hold-down mechanism is removably connected to the bearing (ball) cover outside.
Oil outlet is located at end cap, can guarantee that the bearing of both sides is lubricated with the hole of bearing support side all as filler opening.
Long slightly when the operating time, when Stamping Steel Ribbon produced oil leakage phenomenon because of wearing and tearing, the tight mechanism of adjustable seamless changed sealing load, made and did not leak or few the leakage.When Stamping Steel Ribbon wears up to can't adjust the time, can change fast at the scene.
As to the improving and replenishing of technique scheme, the utility model is further taked the following technical measures or the combination in any of these measures:
Described hold-down mechanism comprise baffle plate, baffle plate is fixed on the housing pin on the bearing (ball) cover and is located at baffle plate and Stamping Steel Ribbon between pressing plate.Can adjust its impacting force by rotating housing pin.
Described pressing plate is located in the seal groove and its outer side surface and bearing (ball) cover flush.
Described Stamping Steel Ribbon is the expanded PTFE Stamping Steel Ribbon.
Beneficial effect: the utility model hold-down mechanism fitted seal bar detachable by adopting, adjustable pressure, the scene of being convenient to is in time adjusted or is changed, and has improved the oil seal performance of gear mechanism, and expanded PTFE Stamping Steel Ribbon cost is low, and sealing is reliably.
Description of drawings
Fig. 1 is an existing bearing oil seal structure schematic representation;
Fig. 2 is a structural representation of the present utility model.
Embodiment
Novel bearing oil seal structure as shown in Figure 2 is provided with bearing 2 between axle 1 and the bearing support 3, makes between axle 1 and the bearing support 3 and can relatively rotate.The distolateral bearing (ball) cover 4 that is fixed with in the both sides of bearing support, bearing (ball) cover 4 is provided with the locking nut 7 that limits axle 1 position with between centers, and axle 1, bearing support 3, bearing (ball) cover 4 and locking nut 7 cooperations form an oily receiving cavity.
When finding that oil leakage phenomenon appears in Stamping Steel Ribbon, rotate housing pin and regulate impacting force, it is not leaked or few the leakage.During as the Stamping Steel Ribbon serious wear, only need turn on housing pin, unclamp baffle plate, take out pressing plate, promptly replaceable Stamping Steel Ribbon, very convenient.
Should be pointed out that present embodiment just lists expressivity principle of the present utility model and effect are described, but not be used to limit the utility model.Any personnel that are familiar with this technology all can make amendment to the foregoing description under spirit of the present utility model and scope.Therefore, rights protection scope of the present utility model should be listed as claims.
Claims (4)
1. novel bearing oil seal structure, comprise axle, bearing support and be located at bearing between the two, the distolateral bearing (ball) cover that is fixed with of bearing support, bearing (ball) cover and between centers are provided with the locking nut of stationary axle and position of bearings, axle, bearing support, form an oily receiving cavity between bearing (ball) cover and locking nut and the bearing, it is characterized in that: offer oil outlet on the described bearing (ball) cover, offer seal groove between described bearing (ball) cover and the locking nut, be provided with Stamping Steel Ribbon in the seal groove, the sealing bar is pressed between bearing (ball) cover and the locking nut by a hold-down mechanism, and described hold-down mechanism is removably connected to the bearing (ball) cover outside.
