Abstract
The utility model relates to a radial bearing inlaid with a hard alloy piece. The internal and the external friction surfaces contacted with an internal and an external sleeves are lined with a plurality of hard alloy pieces which are arranged in a definite geometric shape; the hard alloy pieces are sintered on the internal and the external friction surfaces of the internal and the external sleeves through casting tungsten carbide and copper nickel alloy. The radial bearing inlaid with the hard alloy piece has the advantages that the radial bearing inlaid with the hard alloy piece can be used for occasions having adverse environmental conditions and requiring long service life, and the radial bearing inlaid with the hard alloy piece has high reliability. The radial bearing inlaid with the hard alloy piece can be used for a pin drilling tool in petroleum artesian well, which shows the advantages that other bearings can not replace; the average working life of the radial bearing inlaid with the hard alloy piece can reach more than 300 hours.
Description
The utility model belongs to the radial bearing in the oil-well drilling equipment, particularly a kind of radial bearing that studs with hard alloy blocks.
Three big key components in the drilling equipment of petroleum production at present: rotor, stator and radial bearing.Its radial bearing adopts Bearing Steel to improve wear resistance through a series of heat treatment process.Because the drilling process of petroleum production, its radial bearing is operated in the mud, and work under bad environment is easy to wear, and the life-span is low, seize often occurs and cuts a phenomenon.
The purpose of this utility model provides a kind of radial bearing that studs with hard alloy blocks, improves wear resistance, life-saving.Overcome above-mentioned easy to wearly, seize often occurs and cut a shortcoming and defect.
The purpose of this utility model is achieved in that
A kind of radial bearing that studs with hard alloy blocks is made up of with overcoat interior cover and is it is characterized in that: stud with a plurality of hard alloy blocks of arranging by certain geometrical shape on the contacted relative inside and outside rubbing surface of overcoat in it.
Its hard alloy blocks is the disk of φ 7mm * 3mm.
Its hard alloy blocks also can be the halfround bar slice of R3.5mm * 3mm.
Its hard alloy blocks also can be strip.
Its hard alloy blocks hardness is more than the HRA89, on the inside and outside rubbing surface by the interior overcoat of 80-120 purpose cast tungsten carbide and corronil sintering 35CrMo steel.
The utility model has the advantages that:
It is abominable and require high occasion of life-span, reliability height that the radial bearing that studs with hard alloy blocks can be widely used in environmental conditions.In the application of the thin bar drill tool of oil drilling, more existing the advantage that other bearings can not replace is shown, its operating life is on average more than 300 hours.
Below in conjunction with description of drawings embodiment:
Fig. 1 is the interior cover of the radial bearing schematic representation that studs with hard alloy blocks
Fig. 2 is the radial bearing overcoat schematic representation that studs with hard alloy blocks
A kind of radial bearing that studs with hard alloy blocks is made up of interior cover 1 and overcoat 2, studs with a plurality of hard alloy blocks of arranging by certain geometrical shape 3,4 on the contacted relative inside and outside rubbing surface of overcoat in it.
Its hard alloy blocks is the disk of φ 7mm * 3mm.
Its hard alloy blocks also can be the halfround bar slice of R3.5mm * 3mm.
Its hard alloy blocks also can be strip.
Its hard alloy blocks hardness is more than the HRA89.
Hard alloy blocks by 80-120 purpose cast tungsten carbide and corronil 5 sintering on the inside and outside rubbing surface of interior overcoat that by material is the 35CrMo steel.
