Abstract
The utility model discloses a kind of transmission shafts of circular arc spline structure, the main inner spline housing including on gearbox, internal spline, universal joint, weld yoke, central siphon, flanged yoke, arc-shaped external splines, band circular arc type splined shaft, transmission shaft right end flanged yoke universal-joint, universal joint connecting welding fork, weld yoke connects central siphon one end, central siphon other end connecting band circular arc type splined shaft, with the internal spline cooperation in the arc-shaped external splines on circular arc type splined shaft and the inner spline housing on gearbox.The utility model uses a kind of novel external splines, arc-shaped spline, in the case where meeting transmission shaft use, simplifies transmission shaft structure, be reduced to 5 parts from 7 parts, reduce cost, make transmission shaft light weight, reduces steel and use, 15% or more weight saving, it is energy-saving, it is beneficial to energy conservation environmental protection.
Description
Technical field
The utility model relates to the fields of transmission shaft, and in particular to a kind of transmission shaft of circular arc spline structure.
Background technique
Common single-unit transmission shaft one end is spline fork at present, and one end is flanged yoke structure, and the spline on slip shaft yoke is straight
Straight-tooth inner spline housing cooperates on toothing, with gearbox, meets axial flexible, and slip shaft yoke is connected by universal joint and weld yoke
It connects, upper and lower and left and right the swing of universal joint meets the swing of transmission shaft.
Prior art number of parts is more, and structure is complicated, and transmission shaft weight weight, fabrication cycle is long, and cost is high.
Utility model content
The purpose of the utility model is to overcome the shortcomings of the prior art, and provide a kind of biography of circular arc spline structure
Moving axis.
The purpose of this utility model is completed by following technical solution: the transmission shaft of this circular arc spline structure,
The main inner spline housing including on gearbox, internal spline, universal joint, weld yoke, central siphon, flanged yoke, arc-shaped external splines, band circle
Camber splined shaft, transmission shaft right end flanged yoke universal-joint, universal joint connecting welding fork, weld yoke connect central siphon one end, axis
Pipe other end connecting band circular arc type splined shaft, with the arc-shaped external splines on circular arc type splined shaft and the inner spline housing on gearbox
In internal spline cooperation.
Spline on the arc-shaped external splines is arc-shaped, can be put in the internal spline in the inner spline housing on gearbox
It is dynamic.
The utility model has the following beneficial effects:
1, the utility model external splines novel using one kind, arc-shaped spline, in the case where meeting transmission shaft use,
Simplify transmission shaft structure, be reduced to 5 parts from 7 parts, reduce cost, make transmission shaft light weight, reduces steel and use,
15% or more weight saving, it is energy-saving, it is beneficial to energy conservation environmental protection.

Specific embodiment
Detailed introduction is done to the utility model below in conjunction with attached drawing:
Embodiment: as shown in the picture, the transmission shaft of this circular arc spline structure, the main inner spline housing including on gearbox
1, internal spline 2, universal joint 5, weld yoke 6, central siphon 7, flanged yoke 8, arc-shaped external splines 9, band circular arc type splined shaft 10, transmission shaft
8 universal-joint 5 of right end flanged yoke, 5 connecting welding of universal joint fork 6, weld yoke 6 connect 7 one end of central siphon, and 7 other end of central siphon connects
Tape splicing circular arc type splined shaft 10, in the arc-shaped external splines 9 on circular arc type splined shaft 10 and the inner spline housing on gearbox 1
Internal spline 2 cooperates.
Spline on the arc-shaped external splines 9 is arc-shaped, can be in the internal spline 2 in the inner spline housing 1 on gearbox
Interior swing.It is able to satisfy the axial stretching of transmission shaft, is also able to satisfy the swing of transmission shaft.Newly-designed transmission shaft, using spline
Special construction, the parts such as substitution universal joint 5, weld yoke 6 and slip shaft yoke 4, meets the axial stretching and transmission shaft of transmission shaft
Swing, while 15% or more weight saving, energy conservation and environmental protection.
It is understood that it will be understood by those skilled in the art that the technical solution of the utility model and utility model structure
Think of is subject to equivalent substitution or change all and should belong to the protection scope of the utility model the attached claims.
