Abstract
The utility model relates to a machinery driving device, more particularly a universal driving device in s traditional structure of a driving foot frame or the like on a medical bed, comprising a driving shaft (1), a pin (3) and a universal driving shaft sleeve (4), which is characterized in that the end portion of the driving shaft (1) is equipped with a driving shaft slot (2) vertically equipped along the driving shaft, the driving shaft end portion with the driving shaft slot is equipped inside a universal driving muffle (4), and is fixedly connected with the universal driving muffle (4) into an integration by a shaft pin. Compared with the prior arts, the utility model has a simple manufacturing, low cost and strong practicability, which is widely used in the machinery universal driving device field, more particular suitable for a driving structure with a not so big driving angle, not so high cooperation preciseness and no so fast speed, such as the universal driving device in a driving structure of a medical bed driving foot, bed plate elevator on the back or the like.
Description
[technical field]
The utility model relates to the universal driving device in the drive mechanisms such as driving the instep frame on a kind of mechanical transmission, particularly medical bed.
[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.Existing universal transmission mechanism is more to be to adopt moulding to make, and its major advantage is: easy to use, and ensuring smooth transmission.But also there are many deficiencys in this universal transmission mechanism: one, owing to be injection-molded article, so mechanical strength is low, the normal situation that damage occurs in the use; Its two, the manufacturing process complexity, the cost height, its three, transmit little, the poor reliability of torsion.
[summary of the invention]
The utility model 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 slotted hole type universal driving device, comprise live axle 1, live axle slotted hole 2, 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 slotted hole type 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.
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.
The utility model is compared with prior art, simple in structure, easy to use, good reliability, transmission torsion is big, and the utility model manufacturing is simple, cost is low, practical, be widely used in mechanical universal driving device field, be specially adapted 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.

Referring to Fig. 1, Fig. 7, Fig. 8, Fig. 9,1 is live axle, and 2 is the live axle slotted hole, and 3 is bearing pin, and 4 is the universal drive shaft cover, and 5 is bearing pin, and 6 is transmission shaft, and 7 are the welding signal, and 8 is universal axle sleeve port inclined-plane.
[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, for easy to process, live axle slotted hole 2 can be processed into straight hole, its transverse holes 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.
Shown in Fig. 5,6, the assembly structure relation of visible live axle 1, bearing pin 3, universal drive shaft cover 4, and visible live axle 1 is around bearing pin 3 radially or axial rotation and constitute the structural representation of angle state with transmission shaft.
Referring to Fig. 7,8,9, live axle universal drive shaft cover 4 ends that can directly process at transmission shaft 6, 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.
The end that is shaped on the live axle 1 of slotted hole is placed in the universal drive shaft cover 4, and 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, and has just constituted universal driving device.
Referring to Figure 10, 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 slotted hole type universal driving device is very clear and simple to those skilled in the art.
