Description
Technical Field
The utility model belongs to the technical field of sealing and dust prevention, and particularly relates to a dust-proof self-lubricating shaft sleeve.
Background
The self-lubricating sleeve is generally called as a non-lubricating bearing and is a sliding bearing. The bearing material is generally made of plastic, carbon graphite, or the like, and can operate without lubricating oil or grease. The prior self-lubricating shaft sleeve is embedded by drilling, the lubricating material is easy to fall off, and the two ends of the shaft sleeve have no sealing effect. In actual field operation, a plurality of self-lubricating shaft sleeves and inner holes of the clamping wheel are in a grinding sudden death state, the clamping wheel abrades the toothed plate when sliding with the large star-wheel toothed plate in a static state, and the large star-wheel toothed plate cannot be replaced; the direct economic loss does not cause the problems in sintering production.
Disclosure of Invention
The utility model aims to provide a dustproof self-lubricating shaft sleeve, which can realize the conditions of dust prevention and grinding prevention and can realize 360-degree lubrication at the same time, so that a trolley can well slide with a large star wheel toothed plate of a sintering machine during operation, and the production profit is improved.
The purpose of the utility model is realized by the following technical scheme:
the dustproof self-lubricating shaft sleeve is characterized in that lubricating sealing rings are arranged at two ends of the shaft sleeve, a spiral groove is formed along the surface of the outer circle of the shaft sleeve, and a lubricating material is arranged at the concave part of the spiral groove.
The spiral groove is provided with a trapezoidal section, the lower bottom of the trapezoidal section is positioned at the bottom of the groove, and the upper bottom of the trapezoidal section is positioned at the opening of the groove.
The lubricating material is a tungsten-molybdenum alloy lubricating material.
The lubricating sealing ring is a high-temperature resistant sealing ring.
The utility model has the advantages that:
according to the dustproof self-lubricating shaft sleeve, the lubricating sealing rings are arranged at the two ends of the sleeve, so that the function of preventing dust is achieved in maintenance, and the inner sleeve is lubricated and an inner hole of the outer clamping wheel is not ground; the installation is convenient, and the service life of lubrication is prolonged; the operation period is prolonged, the field maintenance workload is reduced, and the environmental quality is improved.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a view a-a of fig. 1 of the present invention.
Detailed Description
The following further describes the embodiments of the present invention with reference to the drawings.
As shown in fig. 1 and 2, the dustproof self-lubricating shaft sleeve of the present invention comprises a shaft sleeve 1, and is characterized in that lubricating seal rings 2 are arranged at two ends of the shaft sleeve 1, a spiral groove 3 is arranged along the outer circumferential surface of the shaft sleeve 1, and a lubricating material is arranged at the recessed portion of the spiral groove 3.
The section of the spiral groove 3 is a trapezoidal section, the lower bottom of the trapezoidal section is positioned at the bottom of the groove, and the upper bottom of the trapezoidal section is positioned at the opening of the groove. The groove in such a form facilitates storage of the lubricating material and is not prone to leakage.
The lubricating material is a tungsten-molybdenum alloy lubricating material. The tungsten-molybdenum alloy lubricating material is a lubricating body mainly composed of molybdenum disulfide and tungsten disulfide, copper powder, polytetrafluoroethylene and graphite.
The lubricating sealing ring 2 is a high-temperature resistant sealing ring.
The dustproof self-lubricating shaft sleeve abandons the traditional drilling embedded type lubricating mode, adopts the structure that the spiral groove 3 is arranged on the surface of the excircle of the shaft sleeve 1, and the tungsten-molybdenum alloy lubricating material is arranged in the spiral groove 3 to form a sleeve excircle embedded lubricating sealing strip, wherein the lubricating material is the tungsten-molybdenum alloy lubricating material, so that the inner sleeve lubrication and the outer clamping wheel inner hole are effectively ensured not to be ground, the installation is convenient, and the lubricating service life is prolonged. The sleeve is provided with the lubricating sealing rings 2 at two ends of the shaft sleeve 1, so that the sealing is tighter, the device plays a role in preventing dust during operation and maintenance, particularly during maintenance of a sintering machine trolley, the dustproof effect is more obvious, the operation period is prolonged, the on-site maintenance workload is reduced, and the environmental quality is improved.
Claims (4)
