Abstract
The invention provides a cross shaft universal coupling with a lubrication channel, belonging to couplings. The cross shaft universal coupling is characterized in that a ring groove is formed at the middle part of the inner hole wall of a shaft head connecting body, and simultaneously, a bush is pressed on the inner hole wall in an interference mode to enable the ring groove to become a sealed main oil gallery; the top end of each shaft head is turned into a large chamfer or is turned into a stepped shaft section with a small diameter; simultaneously, the top end surface of each shaft head is milled to form a cross groove, and a central through hole which is communicated with the main oil gallery on the shaft head connecting body is axially formed on each shaft head; and in addition, an auxiliary oil gallery which is communicated with the main oil gallery and is provided with internal threads at the outer end section is respectively formed between two adjacent shaft heads on the shaft head connecting body, an oil filling nozzle is installed on each auxiliary oil gallery, and lubricating grease is filled into the main oil gallery from any one of the oil filling nozzles, thereby greatly improving the lubricating conditions and working environment of the cross shaft universal coupling, prolonging the service life of the cross shaft universal coupling, improving the production efficiency and lowering the production cost.
Description
Technical field
The invention belongs to coupling, especially relate to a kind of Hooks coupling universal coupling.
Background technique
Cross-axle universal shaft coupling is widely used on the rolling mill, lubricating between existing cross axle spindle nose and the bearing, only be when mounted, on bearing roller, smear one deck lubricating grease, but during rolling mill work, the many dirt of its high ambient temperature, the metal break flour and the dust in the working environment that produce between the spindle nose of cross axle and the bearing roller all can be assembled in this layer lubricating grease, make lubricating grease rotten dirty, often make the cross axle spindle nose worsen accelerated wear test because of lubricating condition, increase amount of maintenance and working strength of workers, reduced manufacturing efficiency, improved cost of production.
Summary of the invention
The objective of the invention is to propose a kind of cross-axle universal shaft coupling that has lubrication channel, improve the lubricating condition of cross-axle universal shaft coupling effectively, increase the service life, alleviate working strength of workers, enhance productivity, reduce production costs.
The object of the present invention is achieved like this: a kind of cross-axle universal shaft coupling that has lubrication channel, comprise spindle nose and spindle nose connecting body, this spindle nose connecting body is a cirque body, four cylindrical spindle noses are cross and are arranged on the periphery of spindle nose connecting body and formed integrally therewith, it is characterized in that: annular groove is offered at the middle part at the inner hole wall of spindle nose connecting body, interference press-fits lining on this inner hole wall simultaneously, this lining can be the steel lining, make this annular groove become the main oil gallery of sealing, the tip portion of each spindle nose all is lathed big chamfering or car becomes the little step shaft part of diameter, the little 6-8mm of the comparable spindle nose diameter of the diameter of this spindle nose step shaft part, highly can be 3-5mm, simultaneously, equal milling cross groove on the top end of each spindle nose is axially being offered the central through bore that communicates with main oil gallery on the spindle nose connecting body, in addition on each spindle nose, offer respectively at the position between the adjacent spindle nose in twos on the spindle nose connecting body communicate with main oil gallery and the tapped secondary oil duct of outer end section, on each secondary oil duct, pump nozzle is installed.
From any pump nozzle grease up in main oil gallery, this lubricating grease is in each central through bore and the corresponding gap of annotating between spindle nose and the bearing of cross groove, dirty rotten lubricating grease is extruded from the root of spindle nose simultaneously, the lubricating condition and the working environment of cross-axle universal shaft coupling have greatly been improved, increase the service life, enhance productivity, reduce production costs.
The cross-axle universal shaft coupling that has lubrication channel proposed by the invention, simple in structure, safe and reliable, improve the lubricating condition of cross-axle universal shaft coupling effectively, prolonged working life, alleviate working strength of workers, improve manufacturing efficiency, reduced cost of production.
Now in conjunction with the accompanying drawings and embodiments the cross-axle universal shaft coupling that has lubrication channel proposed by the invention is described further.
