Technical Field
The utility model belongs to the technical field of transmission shafts, relates to a universal joint fork, and in particular relates to a novel anti-seismic universal joint fork and a novel anti-seismic universal joint assembly.
Background
The universal driving device is a device for transmitting power between two shafts with the relative positions being changed continuously in the working process, and has the functions of connecting a transmission output shaft and a main speed reducer input shaft which are not on the same straight line, and ensuring that the power can be reliably transmitted under the condition that the included angle and the distance between the two shafts are changed constantly.
Common antidetonation universal joint fork in market sets up the shock attenuation and subtracts the component at transmission shaft and universal joint, like application number "202120690690.3", patent literature of patent name "high strength two-way semi-axis" knows, and it includes the semi-axis body, and the surface both ends of semi-axis body all are equipped with the universal joint, and the surface of two universal joints all is equipped with the collar, all is equipped with the shock pad between two collars and the universal joint, and the both ends of semi-axis body are equipped with cylindric casing and ball cage respectively, all are equipped with antidetonation mechanism in cylindric casing and the ball cage, and two collar surface all with antidetonation mechanism butt.
Above-mentioned universal joint fork reduces the transmission of vibrations through the shock pad, but the moment of torsion of spring structure transmission power is lower, and can't reduce the production of vibrations, and metal spring exists metal fatigue, and the extrusion number of times is too much easily to lead to the spring to become invalid to influence overall structure.
Disclosure of Invention
The utility model aims to solve the problems in the prior art and provides a novel three-pin anti-seismic universal joint fork and a novel three-pin anti-seismic assembly.
The aim of the utility model can be achieved by the following technical scheme: novel antidetonation universal joint fork and subassembly, a serial communication port, including universal joint fork and connecting axle, the connecting axle both ends be equipped with the spring separation blade, the connecting axle on be equipped with two universal joint forks, the connecting axle on be equipped with two guide rings that supply the universal joint fork to fix, and this guide ring is connected with the universal joint fork through fixed pin, be located be equipped with the pressure spring A who supports the guide ring on the connecting axle, and the guide ring is all connected through pressure spring B with the spring separation blade.
In the novel anti-seismic universal joint fork and the assembly, the fork lug connected with the guide ring is arranged on the universal joint fork, and the central axis of the fork lug is parallel to the central axis of the universal joint fork.
In the novel anti-seismic universal joint fork and the assembly, the connecting end is further arranged on the universal joint fork, and the transmission internal spline is arranged in the connecting end.
Compared with the prior art, this novel antidetonation universal joint fork and subassembly is through setting up vibrations absorption that a plurality of group springs produced on each universal joint fork on the connecting axle and reduce vibrations and the noise that universal drive device produced, fork ear axis is parallel with the axis of universal joint fork, reduce the collision that produces when universal drive device shortens the interval, further reduction vibrations, transmission internal spline in the link makes the universal joint fork have simple and convenient connected mode, reduce its installation cost, longer fork ear can hold the connecting axle, make universal structure can adapt to longer transmission space, application range is more extensive.
