Abstract
The present invention relates to a kind of mechanical transmission equipment, in particular, it relates to a universal drive device in the drive structure for driving and lifting foot and back bedplate on the medical bed. Said universal drive device includes drive shaft, pin shaft and universal driving shaft sleeve. Besides, said invention also provides their connection mode and the concrete operation method of said universal drive device.
Description
[technical field]
The present invention relates to drive on a kind of mechanical transmission, particularly medical bed the universal driving device in the drive mechanism of liftings such as pin, back bed board.
[background technique]
In daily many mechanical transmission, all to adopt universal driving device.Drive the structure of pin, back bed board or the lifting of whole bed such as existing medical bed, drive in the lifting process at hand screw mandrel, by the variation of Lift Part position and angle, make the angle that forms dynamic change between live axle and transmission shaft component, so the essential universal driving device that the dynamic change of an adaptation angle is installed between live axle and transmission shaft.The universal driving mechanism of existing medical bed is to adopt the cross axle of structure more complicated to add the pivoted arm structure mostly, has the advantage of ensuring smooth transmission.But this universal driving mechanism so mechanical strength is low, transmit little, the poor reliability of torsion, often occurs situation about damaging owing to be injection-molded article in the use; In addition, manufacturing process complexity, cost height.
[summary of the invention]
The present invention is in order to overcome above-mentioned deficiency, provide a kind of simple in structure, with low cost, easily manufactured, transmit that torsion is big, the universal driving device of reliable performance.
For achieving the above object, design a kind of universal driving device, comprise live axle 1, bearing pin 3, universal drive shaft cover 4, the end of live axle 1 is opened and is shaped on the live axle slotted hole 2 that vertically is provided with along live axle, the driveshaft end that has live axle slotted hole 2 places in the universal drive shaft cover 4, be connected and fixed with universal drive shaft cover 4 by bearing pin 3 and be one, constitute universal driving device.
Above-described live axle slotted hole 2 is a straight hole, and its transverse holes is advisable apart from being slightly larger than bearing pin 3 and constituting to be slidingly matched, and vertical pitch-row should satisfy the action angle between live axle and the transmission shaft.
In order to improve live axle slotted hole 2 and bearing pin 3 quality of fits, live axle slotted hole 2 from two side shaft surfaces to V-shaped the dwindling in hole middle part, constitute and to be slightly larger than the hole that bearing pin 3 can be slidingly matched with bearing pin 3, V-type angle and axle surface longitudinal pitch-row should and live axle and transmission shaft between the action angle adapt.
Universal drive shaft cover 4 can directly be processed in the end of transmission shaft 6, also can connect transmission shaft 6 by the bearing pin 5 or the methods such as 7 of welding.
In order to make the work angle between live axle and transmission shaft bigger, and make the gap of 4 on live axle 1 and universal axle sleeve smaller, can be with the port inner wall Bevel 8 of universal axle sleeve 4.
Live axle 1 drove transmission shaft 6 and rotates by around bearing pin 3 radial and axial motions when the present invention worked.
The present invention compares with prior art, simple in structure, easy to use, good reliability, transmission torsion is big, and the present invention makes simply, cost is low, practical, is widely used in mechanical universal driving device field, particularly be applicable to the drive mechanism that the transmission angle is not too big, the quality of fit requirement is not too high, speed is not too fast, such as the universal driving device in the drive mechanism that drives pin, back bed board lifting etc. on the medical bed.

[embodiment]
Referring to Fig. 1,2,3,4,, a kind of live axle 1 that adopts metallic material or other high-strength materials, open the live axle slotted hole 2 that system one vertically is provided with in its end, the transverse holes of live axle slotted hole 2 is apart from being slidingly matched to constitute with bearing pin 3 that be advisable can not be excessive, and vertically pitch-row should satisfy angle between live axle and the transmission shaft.
Referring to Fig. 5,6,7,8, in order to make live axle slotted hole 2 higher with the quality of fit of bearing pin 3, with live axle slotted hole 2 from two side shaft surfaces to V-shaped the dwindling in hole middle part, the Kong Bingyu bearing pin 3 that formation is slightly larger than bearing pin 3 is slidingly matched, V-type angle and axle surface longitudinal pitch-row should and live axle and transmission shaft between the action angle adapt.
Adopt other high strength linepipe of metal or direct Vehicle Processing one universal drive shaft cover 4 on transmission shaft, the end that is shaped on the live axle 1 of slotted hole is placed in the universal drive shaft cover 4, bearing pin 3 passes through hole and the live axle slotted hole 2 on driving sleeve 4 walls, and bearing pin 3 two ends are fixedly prevented to come off.
Referring to Fig. 9,10,11, universal drive shaft cover 4 ends that can directly process at transmission shaft, and boring the through hole that can pass bearing pin 3 on the axle sleeve wall, the far-end of universal drive shaft cover 4 also can be made tubulose by bearing pin 5 or weld several different methods such as 7 and connect transmission shaft 6.
Referring to Figure 12, for make live axle 1 around bearing pin 3 radially or the angle of axial rotation bigger, the gap that live axle 1 and universal axle sleeve are 4 is smaller, can be processed into inclined-plane 8 at the port inner wall of the universal axle sleeve 4 that is connected with live axle 1.
The technology of above-mentioned this manufacturing universal driving device is very clear and simple to those skilled in the art.
