Abstract
The utility model relates to a flange type rolling spline pair which comprises a spline shaft. A ring of flange type holding frame is uniformly arranged at the periphery of the spline shaft. The holding frame is provided with a plurality of projection blocks. A plurality of load ball bearings are provided between every two projection blocks. Each projection block is internally provided with a plurality of idle load ball bearings. A spline sleeve is sleeved at the periphery of the holding frame. The middle part of an external surface of spline sleeve is provided with a key slot and a circle of through slot, wherein the key slot is communicated with the through slot. The flange type rolling spline pair has the following advantages: compact structure, large contact angle, small deflection and high rigidity. The flange type rolling spline pair is used for the following aspects: trestle and rocker arm of industrial robot, automatic loading/unloading machine, riveting machine, coil winder, electric spark machining machine head, spindle drive shaft of grinding machine and various transmissions.
Description
Technical field:
The utility model relates to a kind of rolling spline pair, particularly a kind of flanged type rolling spline pair is used for the trestle of industrial robot and rocking arm, automatic loader and unloader, riveting machine, Coiler, electric discharge machining machinery head, lapping machine main shaft drives axle, various speed change gear.
Background technique:
Rolling spline pair is a kind of linear motion system, when spline housing utilization ball wherein through on the splined shaft of precision grinding during straight line motion, can transmitting torque.At present, ball in the rolling spline pair is located between splined shaft and the spline housing, makes that the external diameter of spline housing is bigger, causes the whole volume of whole rolling spline pair bigger, and rolling spline pair can't realize precompressed, because can make ball can't realize that straight-line rolling has moved after the precompressed.
Summary of the invention:
The purpose of this utility model is in order to overcome above deficiency, and a kind of compact structure, wrapping angle is big, displacement is little, rigidity is high flanged type rolling spline pair are provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of flanged type rolling spline pair, spline pair comprises splined shaft, the periphery of splined shaft is evenly distributed with the retainer of a circle flanged type, retainer is provided with a plurality of protruding blocks, be provided with a plurality of load balls between per two protruding blocks, be provided with a plurality of unloaded balls in each protruding block, the periphery of retainer is with spline housing, the middle part of the outer surface of spline housing is provided with a keyway and a circle groove, and keyway communicates with groove.
Further improvement of the utility model is: retainer is provided with three protruding blocks, and the angle between two adjacent protruding blocks is 120 °.
The utility model compared with prior art has the following advantages:
Because of the circulation of ball is all carried out in the internal diameter of spline housing, so the external diameter of spline housing can miniaturization, the volume of whole model utility is also compact, wrapping angle of the present utility model is 45 ° simultaneously, wrapping angle is big, and displacement is little, so can obtain high rigidity, and the sense of rotation of ball do not have the gap, can transmit big moment of torsion.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of A-A of the present utility model;
Number in the figure: 1-splined shaft, 2-retainer, 3-load ball, the unloaded ball of 4-, 5-spline housing, 6-keyway, 7-groove, 8-protruding block.
Embodiment:
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.
Show a kind of mode of execution of the utility model flanged type rolling spline pair as Fig. 1 and Fig. 2, spline pair comprises splined shaft 1, the periphery of splined shaft 1 is evenly distributed with the retainer 2 of a circle flanged type, retainer 2 is provided with a plurality of protruding blocks 8, be provided with a plurality of load balls 3 between per two protruding blocks 8, be provided with a plurality of unloaded balls 4 in each protruding block 8, the periphery of retainer 2 is with spline housing 5, the middle part of the outer surface of spline housing 5 is provided with a keyway 6 and a circle groove 7, and keyway 6 communicates with groove 7.Be provided with sealing gasket between the internal surface of the front/rear end of retainer 2 and spline housing 5, the effect of playing sealing between the two.
On the splined shaft outer ring, three protruding blocks 8 have been arranged by 120 ° of equalizations, the load ball 3 at each protruding block 8 two ends can be clamped it, and can apply suitable precompressed naturally according to the contact structure of ball angle, even increase precompressed, ball also can obtain smooth straight-line rolling motion, and all in the internal diameter of spline housing 5, carry out because of the circulation of ball, so the external diameter of spline housing 5 can miniaturization, the volume of whole model utility is also compact, and wrapping angle of the present utility model is 45 ° simultaneously, and wrapping angle is big, displacement is little, so can obtain high rigidity, and the sense of rotation of ball do not have the gap, can transmit big moment of torsion.
