Description
Technical Field
The utility model relates to a mechanical transmission, concretely relates to novel three fork arms sliding universal joint.
Background
The universal coupling utilizes the characteristics of the mechanism thereof to ensure that the two shafts are not on the same axis, can realize continuous rotation of the two connected shafts under the condition of an included angle of the axes, and reliably transmits torque and motion. The cross section of the sliding part of the traditional three-fork rod sliding type universal coupling is circular, the bearing capacity is weaker, in order to realize universal transmission, the joint bearing is adopted to realize angle compensation, but the joint bearing is not suitable for high-speed motion, the lubricating mode is self-lubricating, and the abrasion is larger.
In order to overcome the defects of the common three-fork rod sliding type universal coupling, a novel three-fork rod sliding type universal coupling is designed. This novel three-fork-lever sliding universal coupling has that buffering damping nature is good, and the cost of manufacture is low, processing and simple to operate, and the partial cross section that just slides becomes oval by circular, and bearing capacity is stronger when the same cross-sectional area. Because the universal transmission is realized by adopting the motion form that the sliding ball slides in the V-shaped slide way, the joint bearing of the common three-fork rod sliding type universal coupling is replaced, the lubrication is more facilitated, the energy loss of the coupling is reduced, and the production efficiency is improved.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve that traditional trident pole sliding universal joint bearing capacity is weak, difficult lubricated problem, provide a novel trident pole sliding universal joint, its simple structure, bearing capacity is strong, easily lubricates. The utility model discloses the technical scheme who adopts does: a novel three-fork-rod sliding type universal coupling comprises an input shaft disc, three sliding rods, a three-fork-rod output shaft, an end cover and sliding balls, wherein the input shaft disc is of a structure that the left side is a cylinder and the right side is a disc, a key groove is processed at one end of the left side cylinder of the input shaft disc, three oval sliding holes are uniformly distributed at intervals of 120 degrees on the right side disc, the oval major axis direction of the oval sliding holes is the same as the radius direction of the right side disc of the input shaft disc, the sliding rods are of a structure that one side is an oval column and the other side is a V-shaped slide way, two threaded blind holes are symmetrically processed on the outer side of the right end of the V-shaped slide way, the three sliding rods are in sliding fit with the three oval sliding holes of the right side disc structure of the input shaft disc, the number of the sliding balls is three, a sliding hole is formed in the middle of the sliding ball, the three, the left three fork arms of three-fork arm output shaft utilize the slide opening of sliding ball respectively with three the sliding ball cooperatees, three is processed on three-fork arm output shaft right side has the keyway, the end cover has threely, and is three the end cover passes through the bolt and installs respectively in three the V type slide right-hand member outside of sliding rod to this is injectd threely the sliding distance of sliding ball is in certain extent.
The utility model has the advantages that: simple structure, strong bearing capacity and easy lubrication.
The following describes the present invention in further detail with reference to the accompanying drawings.
