Abstract
The invention discloses a roller universal coupling for the connection between shafts of a mechanical driving part. Two external tooth shaft sleeves (1) which are connected with a driving end and a driven end of connected equipment are respectively arranged at the left end and the right end of the coupling and are nested with inner gear rings (4) to form a plurality of roller spaces which are complete in radial direction; spherical arc rollers (3) are arranged in the spaces; the left inner gear ring and the right inner gear ring (4) are connected by bolts (5) on the flange sides; an O-shaped sealing ring (6) is arranged between the left inner gear ring and right inner gear ring (4); a partition board (7) is arranged between the spherical arc rollers (3) on the left side and the right side; sealing rings (9) are arranged between the left inner gear ring (4) and a baffle (2) and between the right inner gear ring (4) and the baffle (2) and are fixed by screws (8); and the other ends of the sealing rings (9) are fixed by hose clamps (10). The larger displacement between two shafts can be compensated by the arc spherical surfaces of the rollers; the processing process of parts has favorable manufacturability; and the complete mechanical static seal can be realized by an external rubber sealing sleeve, so that the coupling has longer service life and maintenance period.
Description
Technical field
The present invention be a kind of mechanical drive department split axle that is used for industries such as metallurgy, mine, boats and ships, papermaking and heavy machinery with axle between be connected, play the flexible coupling product of the inelastic component of transmitting torque, belong to the manufacturing field of the coupling product that drives the follower rotation.
Background technique
The flexible coupling of inelastic component, at present common have drum-shaped tooth type shaft coupling, cross-axle universal shaft coupling, synchro-nizing universal coupling with ball and sacker, a ball Hooks coupling universal coupling, the flexible coupling of inelastic component, it is big to bear moment of torsion, long service life.But all there is shortcoming separately in these several coupling at present, the processing technology complexity that the angular compensatory amount that has is big, have, cost height, the stressed member wear-out part short, that have in working life that has are difficult for changing, and these several coupling can not adapt to abominable Environmental Conditions all because of adopting motive sealing.
For this reason, develop a kind of flexible coupling of brand-new inelastic component, can have big angle, axial displacement compensation rate, manufacturing is easy, and is convenient for installation and maintenance, long service life, the seal lubrication performance is better, makes it to be used in worse environment, is very important.
Summary of the invention
Technical problem: the objective of the invention is by a kind of brand-new structure, a kind of have big angle, axial displacement compensation rate are provided, manufacturing is easy, convenient for installation and maintenance, long service life, the seal lubrication performance is better, can adapt to the flexible coupling of the inelastic component of rugged environment
Technological scheme: the two ends, the left and right sides of roller Hooks coupling universal coupling of the present invention are respectively equipped with the external tooth axle sleeve that links to each other with the drive end of associated equipment and driven end, external tooth axle sleeve and ring gear are nested to form some radially complete roller spaces, and sphere arc roller places in this space; About two ring gears on flange edge, connect with bolt, about be provided with the O RunddichtringO between two ring gears, be provided with dividing plate between the sphere arc roller of the left and right sides, about be provided with seal ring between two ring gears and the baffle plate, and by screw, the other end of seal ring is fixed by the larynx hoop.
The present invention adopts the intermediary element of arc spherical roller as transmitting torque, ring gear and external tooth axle sleeve tooth depth equal the diameter of roller, roller places in the ring gear radially complete space nested with the external tooth axle sleeve, utilizes the arc sphere of roller to obtain angle and nose balance ability.The outside rubber sealing boot that adopts is realized mechanical completely static seal.
The arc sphere of roller can compensate join the bigger displacement of two between centers; Because roller only bears pressure stress, do not bear shearing stress, and the radius of curvature of arc sphere is big, can bear bigger pressure stress, can reach longer working life; The component technology capability is good; The outside rubber sealing boot that adopts is realized mechanical completely static seal, makes the working life of coupling and maintenance period longer.
Beneficial effect: the present invention adopts the intermediary element of arc spherical roller as transmitting torque, can compensate join bigger angular displacement of two between centers and axial displacement; Because ring gear and external tooth axle sleeve tooth depth equal the diameter of roller, so roller only bears pressure stress, do not bear shearing stress, and the radius of curvature of arc sphere are big, can bear bigger pressure stress than ball, so can reach longer working life; The arc roller is convenient to realize batch process, and technology capability is good, and low to equipment and frock requirement, processing cost is lower, and ring gear and external tooth axle sleeve are facing directly of rule, do not need special purpose machine tool; The outside rubber sealing boot that adopts is realized mechanical completely static seal, can guarantee that inner lubricating condition is not subjected to the influence of external environment condition, prolongs the working life and the maintenance period of coupling.

Fig. 1 is that figure is partly cutd open in front of the present invention.
Fig. 2 is an axial sectional view of the present invention.
Fig. 3 is a roller outline drawing of the present invention.
Wherein have: external tooth axle sleeve 1, baffle plate 2, roller 3, ring gear 4, bolt 5, O RunddichtringO 6, dividing plate 7, screw 8, seal ring 9, larynx hoop 10.
Embodiment
Two external tooth axle sleeves 1 of roller Hooks coupling universal coupling involved in the present invention link to each other with the drive end and the driven end of associated equipment respectively, external tooth axle sleeve 1 is nested to form some radially complete roller spaces with ring gear 4, roller 3 places in this space, and two ring gears 4 connect with bolt 5 on flange edge.Be provided with O RunddichtringO 6 between two ring gears, the outside is provided with seal ring 9, and is fixing with screw 8 and larynx hoop 10.When drive end rotated, the path that moment of torsion transmits was as follows: driving shaft---drive end external tooth axle sleeve---drive end roller---drive end ring gear---bolt---driven end ring gear---driven end roller---driven end external tooth axle sleeve---driven shaft.
The arc sphere of roller can compensate join bigger angular displacement of two between centers and axial displacement; Because ring gear and external tooth axle sleeve tooth depth are equal to the diameter of roller, so roller only bears pressure stress, do not bear shearing stress, and the radius of curvature of arc sphere is big, can bear bigger pressure stress than spherical ball, so can reach longer working life; The arc roller is convenient to realize batch process, and technology capability is good, and low to equipment and frock requirement, processing cost is lower, and ring gear and external tooth axle sleeve are facing directly of rule, do not need special purpose machine tool; The outside rubber sealing boot that adopts is realized mechanical completely static seal, can guarantee that inner lubricating condition is not subjected to the influence of external environment condition, makes the working life of coupling and maintenance period longer.
