Abstract
The utility model provides a sliding plate seal ball coupler comprising an outer groove shaft sleeve, compression bolts, a seal ring, connecting bolts, an inner groove ring, balls, and a sealing pressing plate. The sliding plate seal ball coupler is characterized in that a sealing annular sliding plate is disposed in a cavity formed by the inner groove ring, the outer groove shaft sleeve and the sealing pressing plate and a gap is left between the outer ring of the sealing annular sliding plate and the inner groove ring. The sliding plate seal ball coupler allows the bevel of two coupled shafts to be large and to furthest reach 10 degrees, so that the adaptability of the coupler is improved. The sliding plate seal ball coupler is characterized by reliable seal and long service lifetime.
Description
Technical field: the utility model relates to a kind of coupling that connects the diaxon transmitting torque, particularly a kind of skid plate seals ball coupling.
Background technique: the existing ball coupling that connects the diaxon transmitting torque, referring to accompanying drawing 1, it mainly is comprised of water jacket axle sleeve 1, hold-down bolt 2, seal ring 3, connecting bolt 4, inside groove circle 5, ball 6, sealing gland 7.The deficiency that it in use exists is: 1, can't satisfy seal request when knuckle is larger, cause lubricant oil to leak fast; 2, installation precision reduces after the equipment that is connected uses a period of time, and after knuckle surpassed 1.5 degree, it can be in abnormal operating state, not only can cause damage to coupled equipment, and also greatly reduces the working life of coupling itself.
Summary of the invention: the purpose of this utility model is, the deficiency that in use exists for existing ball coupling shaft apparatus, and the skid plate seals ball coupling of a kind of good sealing effect, long service life is proposed.
Can realize the utility model purpose by following technical proposals, a kind of skid plate seals ball coupling, comprise water jacket axle sleeve, hold-down bolt, seal ring, connecting bolt, inside groove circle, ball, sealing clamp, it is characterized in that, be provided with the sealing ring slide plate in the cavity that forms between inside groove circle and water jacket axle sleeve and the sealing clamp three, be provided with the gap between sealing ring slide plate outer ring and the inside groove circle.
The formula of the radial gap amount C of sealing ring slide plate outer ring and inside groove circle is C 〉=0.5B*tag α, wherein B: the axial distance between two sealing ring slide plates; α: be connected the diaxon shaft axis and depart from the knuckle that causes; α=arctag δ/H, wherein δ: be connected the bias of diaxon shaft axis; H: the distance between two circle balls;
According to requirements different in the operation, except the ball transmitting torque is set, each corresponding tooth of establishing transmitting torque of pin, spherical roller transmitting torque or inside groove circle and water jacket axle sleeve joining place can be set also between inside groove circle and the water jacket axle sleeve.
According to requirements different in the operation, the inside groove circle can be integrated type, also can be split type.
According to requirements different in the operation, sealing ring slide plate and water jacket shaft room can be established seal ring, also can not establish seal ring.
Effect of the present utility model is: 1, allow the knuckle of coupled diaxon large, maximum can reach 10 degree, and this has increased the adaptability of coupling greatly; This is because sealing ring slide plate of this coupling has the larger space that moves radially in seal groove, simultaneously again outside fluted shaft put to do and freely move axially and swing, thereby make it allow the knuckle of coupled diaxon large; 2, sealing is reliable, and this is that mainly the sealing of sealing, slide plate and the seal groove of slide plate and water jacket axle sleeve can not be subject to the impact of knuckle; 3, long service life, this mainly is that reliable and stable sealing effect has been arranged, thereby has greatly improved the wear resistance that coupling bears the moment of torsion position.
Below in conjunction with drawings and Examples the utility model is further set forth:
Description of drawings:
Accompanying drawing 3 is a kind of sectional structure schematic representation of implementing state of the present utility model.
Embodiment:
Referring to accompanying drawing 2, a kind of skid plate seals ball coupling, it is comprised of water jacket axle sleeve 1, hold-down bolt 2, seal ring 3, connecting bolt 4, inside groove circle 5, ball 6, sealing gland 7, sealing ring slide plate 8.Sealing ring slide plate 8 is located in the cavity that forms between inside groove circle 5 and water jacket axle sleeve 1 and sealing clamp 7 threes, is provided with the gap between sealing ring slide plate 8 outer rings and the inside groove circle 5.According to requirements different in the operation, except the ball transmitting torque is set, each corresponding tooth of establishing transmitting torque of pin, spherical roller transmitting torque or inside groove circle 5 and water jacket axle sleeve 1 joining place can be set also between inside groove circle 5 and the water jacket axle sleeve 1.According to requirements different in the operation, inside groove circle 5 can be integrated type, also can be split type.According to requirements different in the operation, 1 on sealing ring slide plate 8 and water jacket axle sleeve can be established seal ring 3, also can not establish seal ring 3.
Referring to accompanying drawing 3, being provided with the gap between sealing ring slide plate 8 outer rings and the inside groove circle 5 is that radial gap amount C is determined by formula C 〉=0.5B*tag α, wherein B: the axial distance that two sealing ring slide plates are 8; α: be connected the diaxon shaft axis and depart from the knuckle that causes; α=arctag δ/H, wherein δ: be connected the bias of diaxon shaft axis; H: the distance that two circle balls are 6.When the connection existence radially departs from the two-parallel axis of δ, will there be the α angle in the center line of internal tooth and hermetic unit with the shaft axis of external tooth fluted shaft cover 1, and all will there be certain amount of moving radially in any point on the inside groove circle 5 with the external tooth shaft axis.1, the axle of inside groove circle 5 can compensate moving radially of inside groove circle 5 and water jacket shaft axis because sealing ring slide plate 8 can radially move along A, B two planes in seal groove; 2, because of sealing ring slide plate 8 outside on the fluted shaft cover 1 along the C spot wobble with move axially, can compensate the center line of internal tooth and hermetic unit and the α angle of the shaft axis existence of externality shaft; 3, the ellipse that forms of sealing place of seal ring and water jacket axle sleeve, because major axis and minor axis differ less, can be by the elastic compensating of seal ring.
