Description
Technical Field
The utility model relates to a machine part, in particular to novel screw thread formula shaft coupling.
Background
The coupling is a mechanical part used for coupling two shafts in different mechanisms to enable the shafts to rotate together so as to transmit torque. In the high-speed heavy-load power transmission, some couplings also have the functions of buffering, damping and improving the dynamic performance of a shaft system. The power machine is connected with the working machine by a coupler, which is the most common connecting part for mechanical product shafting transmission. Common shaft couplings are generally used in high-strength motion mechanisms, and in order to ensure reliable work and reliable service life, the manufacturing cost of the common shaft couplings is high. Sometimes, only the two shafts need to be normally connected, and the small load and low rotating speed operation needs to be ensured, so that the coupler is used for fixing and reliable, but the performance and the cost of the coupler are wasted. Therefore, the design scheme of the light-weight coupling is provided for the patent.
SUMMERY OF THE UTILITY MODEL
Therefore, to foretell problem, the utility model provides a novel screw thread formula shaft coupling of light-weight of novel structure simple, low in production cost, be applicable to the low rotational speed operation of small-load.
In order to solve the technical problem, the utility model discloses take following scheme: the utility model provides a novel screw thread formula shaft coupling, includes the connecting axle, with first nut and the second nut of connecting axle both ends looks adaptation, the shaft hole has been seted up to the connecting axle, the outer circumference in connecting axle both ends is equipped with first threaded connection portion and the second threaded connection portion by the outside extension in middle part respectively, the circular cone pipe screw thread that external diameter gradually diminishes is extended outwards by the middle part to the screw thread on first threaded connection portion and the second threaded connection portion.
In a further improvement, the thread forms of the conical pipe threads of the first threaded connecting part and the second threaded connecting part are triangular.
Further improvement, the connecting shaft is formed by adopting a PLA material to directly print in a 3D mode through a 3D printer.
In a further improvement, the first threaded connecting part and the second threaded connecting part at two ends of the connecting shaft are provided with slots along the diameter of the axis.
Further improvement, first nut and second nut adopt the direct 3D of PLA material to print integrated into one piece for adopting by the 3D printer.
By adopting the technical scheme, the beneficial effects of the utility model are that: through overlapping first nut and second nut on the diaxon that will connect, and embolia connecting axle one end on one of them axle, screw nut and connecting axle one end after confirming the position, under the effect of circular cone pipe screw thread, first nut cooperation connecting axle will tightly clip epaxial that first nut cover established, another axle inserts the connecting axle other end, screw the second nut who embolias the axle in advance equally, second nut cooperation connecting axle will tightly clip epaxial that second nut cover established, make the diaxon can high-speed joint well, novel structure is simple, low in production cost, be applicable to the light-weight level of the low rotational speed operation of low load, adopt PLA material direct printing integrated into one piece through adopting the 3D printer, make the utility model discloses a shaft coupling light in weight, with low costs, connection performance is reliable, through set up the fluting on the first threaded connection portion at connecting axle both ends and second threaded connection portion and make the axle hole that the axle that the change that wants the hookup inserted of hookup, the installation is convenient, but wide popularization and application.
