Abstract
The utility model belongs to the field of shaft mechanisms and especially belongs to the air pressure-fired type bearing seal flange of a diamond beaded saw. The utility model provides the air pressure-fired type bearing seal flange of a diamond beaded saw. One end of the air pressure-fired type bearing seal flange is provided with a sealing ring groove. The air pressure-fired type bearing seal flange of a diamond beaded saw is characterized in that an inner hole between the end face of a flange and the sealing ring groove is machined with an internal thread. The rotating direction of the inner thread and the shaft rotating direction within the inner thread accord with a relationship described as follows: when the end face of the flange is viewed from the end of the sealing ring and the shaft rotating direction is anticlockwise, the inner thread of the flange is levorotatory; when the shaft rotating direction is clockwise, the inner thread of the flange is dextrorotatory. According to the utility model, through machining an internal thread of a specific rotating direction in the inner hole of a flange, air flow is discharged to the outside through a gap between the flange hole and a shaft neck during the shaft rotation process. Therefore, external dusts, sawdust and other impurities are prevented from entering a bearing, so that the service life of the bearing is prolonged.
Description
Technical field
The utility model belongs to the axis mechanism field, especially belongs to air micro positive pressure formula bearing seal flange plate.
Background technique
Many rope diamond wire saws came out over 20 years; Except that being used for mining, outside the shaping of waste material, also be widely used in the processing of special-shaped stone product; In the special dimensions such as dismounting of discarded industrial building, use is arranged also, will produce tiny pollutants such as amounts of dust, sawdust during its work.The sealing means of many at present rope bearings that diamond wire saw adopted is as shown in Figure 1; This bearing only uses oil sealing sealing; In order not produce interference between flange plate and the axle, gapped between flange plate endoporus and the axle, the pollutant that outside dust, sawdust etc. are tiny is prone to the entering bearing inside from the gap; Accelerate bearing wear, cause bearing life and shorten.
Summary of the invention
The utility model purpose is to overcome the shortcoming that the existing oil sealing sealing mode of above-mentioned many rope diamond wire saws exists; Provide a kind of foreign material such as outside dust, sawdust that can stop to get into bearing inside, improve the diamond wire saw air micro positive pressure formula bearing seal flange plate of bearing working condition.
The technological scheme that the utility model adopted is a kind of diamond wire saw air micro positive pressure formula bearing seal flange plate; The one of which end has seal groove; Its main points are, on the endoporus between flange plate end face and the seal groove, are processed with internal thread, relation below described internal thread rotation direction and its inner axle sense of rotation exist: seen to the flange plate end face by the seal ring end; When the sense of rotation of axle when being counterclockwise, then the flange plate internal thread is left-handed; When the sense of rotation of axle when being clockwise, then the flange plate internal thread is dextrorotation.
The utility model is not changing original gap between flange plate endoporus and the axle; On the flange plate endoporus, process the internal thread of specific rotation direction; When axle rotates, will drive axial air is compressed along the flange plate internal thread; Thereby produce a air-flow from gap vent the air overboard flange plate endoporus and axle journal between identical with thread rotary orientation, it is inner that this air-flow can stop tiny pollutant such as outside dust, sawdust to get into bearing, prolonged the working life of bearing.
The utility model has inlet hole on the circumference of flange plate, inlet hole leads to the bottom of flange plate internal thread near the seal groove end.Pressurized gas through compression can be through outlet pipe to flange plate inlet hole supply flow, the sizeable pressurized air of pressure, and air-flow discharges along screw thread, stops foreign material to get into better.
The inlet hole of the utility model is the through hole of being made up of the hole that multistage links to each other.Make that the layout of air inlet pipeline is more flexible, have more adaptability.
The advantage of the utility model is; Through on the endoporus between flange plate end face and the seal groove, processing the internal thread of specific rotation direction; Drive surrounding atmosphere during the axle rotation and be compressed air-flow from gap vent the air overboard flange plate hole and axle journal between identical of generation with thread rotary orientation along the flange plate internal thread; Thereby stop foreign material such as outside dust, sawdust to get into bearing, prolong the working life of bearing.And, add air flow and stop foreign material to get into further through on flange plate, setting up gas handling system.

Embodiment
Like Fig. 2, Fig. 3, Fig. 4, shown in Figure 5; A kind of diamond wire saw air micro positive pressure formula bearing seal flange plate; The one of which end has seal groove 23, on the endoporus between flange plate end face and the seal groove 23, is processed with internal thread 21, relation below described internal thread 21 rotation directions and its inner axle sense of rotation exist: seen to the flange plate end face by the seal ring end; When the sense of rotation of axle when being counterclockwise, then flange plate internal thread 21 is left-handed; When the sense of rotation of axle when being clockwise, then flange plate internal thread 21 is dextrorotation.
Have inlet hole 22 on the circumference of flange plate 2, described inlet hole 22 leads to the bottom of flange plate internal thread 21 near seal groove 23 ends, and the outlet pipe that can pass through blower fan is to flange plate inlet hole 22 air feed.In order not destroy the outer step of flange plate sealed end, inlet hole 22 is the through hole of being made up of the hole that multistage links to each other, and is unaffected to guarantee flange plate intensity.
