Abstract

An angle transmission shaft is applied to high power transmission. Cross holes which are not communicated with each other are formed in an earhole fork; a bearing seat and an angle shaft assembly are arranged in a horizontal hole of the earhole fork; a first bearing is arranged between the bearing seat and the angle shaft assembly; two ends of a double-fork are embedded into a hole of the angle shaft assembly through small shafts and universal joint bearings respectively; a second bearing is arranged between the angle shaft assembly and the earhole fork; the four small shafts are arranged in a radial hole of the earhole fork, wherein the four small shafts and the double-fork are arranged symmetrically; the each side of every small shaft is provided with a connecting ring; every universal joint bearing which is arranged between the two corresponding connecting rings is locked on the corresponding connecting rings and the corresponding small shaft through an elastic baffle ring for a hole; the four small shafts are connected with four threaded holes of the double-fork respectively. Compared with low inertia structures, the vibration is greatly reduced, the strength is high, the abrasion is reduced, the early failure can be effectively avoided, the service life is long, the installation and the debugging are convenient, the unconstrained effect is achieved, and the torque, the speed and the reliability of the angle transmission shaft are greatly improved.

Description

Angle transmission shaft

Technical field

The present invention relates to technical field of mechanical transmission, specifically a kind of high-power angle drive axle assembly.

Background technique

Coupling is important coupling, but under the condition that pivot angle is large, coupling keeps the transmission of high rotating speed, high pulling torque, not only make coupling arrange in use and limited, easy generation vibrations and noise are installed, particularly after coupling interaxial angle improves, its warping force, speed especially reliability reduce suddenly.

Summary of the invention

For overcoming the deficiencies in the prior art, goal of the invention of the present invention is to provide a kind of angle transmission shaft, with realize installing simple, vibrating noise is little and can improve the object of warping force, speed, reliability.

For achieving the above object, the two ends of the two fork of the present invention are respectively through earhole fork and Flange joint; The hole having cross mutually not through in earhole fork, the transverse holes of earhole fork is built with bearing support and angle axle assembly, bearing one is contained between bearing support and angle axle assembly, the two ends of two fork embed in the hole of angle axle assembly by little axle and universal joint bearing respectively, and bearing two is contained between angle axle assembly and earhole pitch; Be contained in the radial hole that earhole pitches with symmetrically arranged four the little axles of two fork, connecting ring is equipped with in the both sides of little axle, and universal joint bearing is therebetween locked on connecting ring and little axle by circlip for hole, and four little axles connect with four tapped holes of two fork respectively.

Described universal joint bearing band selfsealings.

Described angle axle assembly has two angle axles, is sealed by O type circle.

The present invention compared with prior art, due to the inertia that interconnection system is lower, makes vibrations greatly reduce, and system strength strengthens, and product can be made to reduce bending susceptibility, reduce wearing and tearing, effectively can avoid early failure phenomena, long service life; Installation and Debugging are convenient, arrange that installation is unrestricted; Particularly after coupling interaxial angle improves, its warping force, speed especially reliability can significantly improve.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

Embodiment

As shown in Figure 1, the two ends of two fork 9 are connected with flange 1 through earhole fork 2 respectively; The hole having cross mutually not through in earhole fork 2, the transverse holes of earhole fork 2 is built with bearing support 3 and angle axle assembly 8, angle axle assembly 8 has two angle axles, sealed by O type circle, bearing 1 is contained between bearing support 3 and angle axle assembly 8, bearing 1 is plane needle roller thrust bearing, has two, between each bearing support 3 and angle axle assembly 8 each one; The two ends of two fork 9 are embedded in the hole of connecting ring 4 respectively by little axle 10 and universal joint bearing 1, bearing 27 is contained in angle axle assembly 8 and earhole is pitched between 2, bearing 27 is drawn cup needle roller bearing, has four, each angle axle assembly 8 and earhole between pitching 2 each two; Being contained in earhole with symmetrically arranged four the little axles 10 of two fork 9 pitches in the radial hole of 2, connecting ring 1 is equipped with in the both sides of little axle 10, universal joint bearing 5 is therebetween locked at connecting ring 4 with on little axle 10 by circlip for hole 6, four little axles 10 connect with two fork 9 four tapped holes respectively, and selfsealings are with by universal joint bearing 5.
