Embodiment
Below the technological scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Embodiment based in the present invention, those of ordinary skills, not making all other embodiments that obtain under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention comprises:
A universal slip joint, comprising: universal joint body 1 and transmission shaft 2.
Described universal joint body 1 connects described transmission shaft 2, described transmission shaft 2 comprises front propeller shaft and intermediate support, described universal joint body 1 comprises shell, inner casing and bearing, described shell is connected by described bearing with described inner casing, the inner side surface of described shell is provided with projection, the outer side surface of described inner casing is provided with the groove matching with described projection, inner casing is arranged on the inside of shell, can drag according to actual needs inner casing in use and adjust length, easy to use, stable output, the rotation angle of described transmission shaft 2 is less than 45 °, the rotational angle range that meets general connected element, vibrate little, reduced the damage of parts, noise is little, transmission output is uniform and stable.
Preferably, described universal joint body 1 is stainless steel with the material of described transmission shaft 2, material is hard, safety and environmental protection, sturdy and durable, wear-resistingly anti-ly fall, long service life.
Preferably, the lateral cross section of described shell be shaped as circle, bearing capacity is large, stressed even, sturdy and durable.
Preferably, being shaped as of the lateral cross section of described inner casing is circular, square, hexagonal a kind of, the difform inner casing of different choice that can be according to actual needs, and gripping power is good, compatibility is wide.
The beneficial effect of universal slip joint of the present invention is:
One, by adopting extending universal joint to realize freely changing of length, stablized the output of axle power, novel structure, safe and reliable, convenient and practical, compatible wide, sturdy and durable;
Two, by adopting the inner side surface of shell to be provided with projection, the groove that adopts the outer side surface of inner casing to be provided with to match with projection and the inner casing inside that is arranged on shell, can drag according to actual needs inner casing in use and adjust length, easy to use, stable output;
Three, with respect to general universal slip joint, the rotation angle of the transmission shaft of the universal slip joint is here less than 45 °, meets the rotational angle range of general connected element, vibrates that little, to have reduced parts damage, noise are little, transmission output is uniform and stable.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
