Abstract
The utility model discloses a quick-change hexagonal universal joint. The quick-change hexagonal universal joint comprises a transmission shaft and a universal joint main body, wherein the head of the transmission shaft is a hexagonal transmission shaft and an annular groove is formed in the middle part of the transmission shaft; the head of the universal joint main body is a hexagonal transmission bush matched with the hexagonal transmission shaft, two symmetrical steel ball basin holes are formed in the peripheral portion, corresponding to the annular groove, of the hexagonal transmission bush, the two symmetrical steel ball basin holes are communicated with a hexagonal hole, and steel balls are arranged in the steel ball basin holes; a sliding sleeve is arranged at the periphery of the hexagonal transmission bush, a spring is arranged between the sliding sleeve and the hexagonal transmission bush, one end of the spring is movably connected with the outer shaft shoulder of the hexagonal transmission bush, while the other end of the spring is movably connected with a shaft shoulder arranged in the middle part of an inner hole of the sliding sleeve, and when the spring is in a free state, the shaft shoulder in the middle part of the sliding sleeve is pressed on the steel balls. The quick-change hexagonal universal joint is capable of realizing transmission of a large torsional moment and also can be mounted and demounted quickly.
Description
Technical field
The utility model relates to mechanical transmission component assembly manufacturing technology field, relates in particular to a kind of hexagonal quick change universal joint.
Background technique
At present, being mechanically used for transfer motion power drive assembly used is generally cross universal and cuts.Existing universal joint cross, transmission shaft is connected and transmission by lateral pin with universal joint main body, because the transmission of single cylindrical pin, the torsion of transmission is little, and lateral pin and transmission shaft and universal joint main body are by interference fit, Gu installation and dismantling are not very convenient, the torsion of transmission is little, dismounting inconvenience, cannot accomplish large torque transmission, cannot fast assembling-disassembling.
Model utility content
The purpose of this utility model is the defect for above-mentioned prior art, and a kind of hexagonal quick change universal joint is provided, can the larger torsional moment of transmission, and again can fast assembling-disassembling.
To achieve these goals, the technological scheme that the utility model adopts is:
A kind of hexagonal quick change universal joint, comprises transmission shaft and universal joint main body, and the head of described transmission shaft is hexagonal transmission shaft, and the middle part of hexagonal transmission shaft is provided with annular groove; The head of described universal joint main body is the hexagonal drive sleeve suitable with hexagonal transmission shaft, the peripheral part of described hexagonal drive sleeve is that circumference, endoporus are six rib holes, described hexagonal drive sleeve is provided with two symmetrical steel ball basin holes in the perimembranous corresponding with annular groove, communicate with six rib holes, the built-in steel ball in steel ball basin hole; In the periphery of described hexagonal drive sleeve, flip sleeve is set, between flip sleeve and hexagonal drive sleeve, be provided with spring, one end of spring is flexibly connected with the outer shaft shoulder of hexagonal drive sleeve, one end is flexibly connected with the shaft shoulder that flip sleeve endoporus middle part arranges, when spring is during in free state, the shaft shoulder at flip sleeve middle part is pressed on steel ball.
As to improvement of the present utility model, on described hexagonal transmission shaft, be provided with flip sleeve is carried out to spacing snap ring.
As to improvement of the present utility model, described annular groove is arc groove.
As to improvement of the present utility model, described spring is stage clip.
Compared with prior art, the beneficial effects of the utility model are:
Hexagonal quick change universal joint of the present utility model, transmission shaft and universal joint main body, match with hexagonal drive sleeve by the hexagonal transmission shaft of two parts, realizes hexagonal transmission, increases transmission torsion; When flip sleeve pulled down, the steel ball on universal joint main body two limits is divided right and left, and at this moment transmission shaft can up pull out, make transmission shaft and universal joint body portion from, realize quick-detachment, simultaneously flip sleeve automatically replies under the effect of spring, the steel ball return on two limits; When installation, by flip sleeve pulled down, the steel ball on two limits can be toward dividing right and left, transmission shaft down packs in the main body hexagonal drive sleeve of universal joint, decontrols flip sleeve simultaneously, and flip sleeve can automatically reply under the effect of spring, flip sleeve is limited after offseting with snap ring, flip sleeve is in place, and two limit steel balls snap in the circular arc annular groove of transmission shaft, completes transmission shaft is connected with the installation of universal joint main body; Realize the function of quick-clamping, quick change.Hexagonal quick change universal joint of the present utility model, can the larger torsional moment of transmission, again can fast assembling-disassembling.
