Abstract
The utility model relates to a transmission torsion bar with safety protection function has solved the problem that present constant diameter torsion bar exists. Including the involute spline axle at both ends and the optical axis of middle part, the involute spline axle diameter at both ends is big, and the optical axis diameter of middle part is little, is the R100 rounding off from the involute spline axle to the optical axis, and transmission torsion bar 's material is 45CrNiMoVA, and the involute spline axle is 6f6h with the cooperation of drive disk assembly, and the involute spline number of teeth at both ends is the same with the modulus. The utility model discloses simple structure uses reliably, and it is convenient to change, simultaneously because the selection of its material still has the shock attenuation effect.
Description
Technical field:
This utility model relates to a kind of power transmission shaft, is specifically related to a kind of transmission with safety protection function and turns round axle.
Background technology:
For drive system, the connection between the drive disk assembly of two relative opposition uses elasticity even typically as far as possible
Connecing mode, such as cage universal joint and cross axle connect.In the case of being limited by space or structure, two
The connection of person can only use power transmission shaft, and this power transmission shaft is compared with common power transmission shaft, needs have bullet
Property transmission moment of torsion effect.Simultaneously as drive disk assembly is relatively costly, increase drive disk assembly running into moment of torsion
In the case of may damaging, this power transmission shaft can also play autotomys thus protects the action of fuse of drive disk assembly.
Current this power transmission shaft is isometrical torsion bar, and the reaction for moment of torsion is insensitive, while ensureing moment of torsion transmission
Run into and can not twist off in time so that drive disk assembly is damaged when moment of torsion increases suddenly.
Utility model content:
This utility model, by providing a kind of non-isometrical transmission to turn round axle, solves asking of current isometrical torsion axle existence
Topic.
This utility model is realized by techniques below scheme:
A kind of transmission with safety protection function turns round axle, including involute splined shaft and the middle part at two ends
Optical axis, the involute spline shaft diameter at two ends is big, and the shaft diameter of middle part is little, from involute spline
Axle is to optical axis rounding off.
It is 100mm from involute splined shaft to optical axis rounding off radius.
It is 45CrNiMoVA that the material of axle is turned round in transmission.
Involute splined shaft is 6f/6h with coordinating of drive disk assembly.
The involute spline number of teeth at two ends is identical with modulus.
This utility model simple in construction, uses reliable, and it is convenient to change；Simultaneously because the selection of its material, also
There is damping effect.
Accompanying drawing illustrates:
Fig. 1 is that this utility model uses state diagram；
Fig. 2 is this utility model structural representation.
Detailed description of the invention:
As shown in Figure 1, 2, this utility model is that axle is turned round in a kind of transmission with safety protection function, is arranged in
Between two relatively independent drive disk assemblies 1 and 3, its shape is designed as " bone ear of maize " shape, including two
The involute splined shaft of end and the optical axis of middle part, the involute spline shaft diameter at two ends is big, middle part
Shaft diameter little, from involute splined shaft to optical axis use R100 rounding off, it is to avoid stress concentrate, protect
After card runs into the emergency case that moment of torsion increases, transmission is turned round axle and is first ruptured at optical axis, thus by controlling the diameter of axle
Size ensure that its " electric fuse " acts on.It is 45CrNiMoVA that the material of axle 2 is turned round in transmission.Involute flower
Coordinating between key axle with drive disk assembly 1,3 is 6f/6h, it is ensured that the function of elastic transmission moment of torsion.Two ends are gradually
The spline tooth number that bursts at the seams is identical with modulus, can quick-replaceable after turning round axle fracture for guarantee.
