Abstract
The utility model discloses a kind of splined shaft of the chromium plating for motor in electric automobile with sealing ring.The splined shaft is provided with ring groove, sealing ring is provided with the ring groove and whole splined shaft is provided with the electrodeposited coating of crome metal.First then are arranged on sealing ring in annular groove, then the spline housing with lubricating oil is enclosed within splined shaft by the upper metal hard chromium layers of splined shaft plating during use.The utility model improves the wearability of splined shaft, inoxidizability, while preventing same metal from cold welding occurring and spline pair oil leak is solved the problems, such as, alleviates the shock of splined shaft and spline housing.Hardness, surface flatness, inoxidizability and the sealing property of splined shaft are improve, so that the abrasion of splined shaft and spline housing in power train process is effectively reduced, so as to improve the service life of splined shaft.
Description
Technical field
The utility model is related to the motor component for shaped traffic device.
Background technology
In recent years, under ecological environmental pollution and the social background of fossil fuel energy crisis, the new energy of electric drive form
Source automobile arises at the historic moment.Electric automobile of the prior art coordinates to replace using asynchronous machine or synchronous motor with decelerator
Engine and gearbox in orthodox car, constitute the dynamical system of pure electric automobile.Asynchronous machine or synchronous motor are by flower
Key axle realizes the connection with decelerator with the cooperation of decelerator spline housing, and in power train process, spline pair is due to material
And easily there is cold welding, oxidation the reason for sealing, and cause wear out failure, so as to have impact on spline pair (including splined shaft and flower
Key set) service life.
Therefore, there is cold welding and aoxidize in the splined shaft and decelerator spline housing for how avoiding asynchronous machine and synchronous motor
Abrasion is caused, the sealing of asynchronous machine and synchronous motor splined shaft, the service life of the splined shaft that avoids wearing and tearing, extend is improved,
As those skilled in the art's technical problem urgently to be resolved hurrily.
The content of the invention
The utility model provides a kind of splined shaft, to avoid the oxidation of asynchronous machine or synchronous motor splined shaft, improves
The sealing that splined shaft coordinates with spline pair, so as to reduce abrasion, extends the service life of splined shaft.
The technical scheme used to realize the utility model purpose is a kind of such, plating for motor in electric automobile
Splined shaft of the chromium with sealing ring, including splined shaft and electrodeposited chromium layers, and at least one sealing ring.
There is at least one annular groove on the splined shaft.The annular groove by splined shaft outer surface each flower
Key teeth is cut off.Path rs of the internal diameter RH of the annular groove less than splined shaft.
The electrodeposited chromium layers cover the outer surface of splined shaft.
The quantity of the sealing ring is equal with the quantity of annular groove.One sealing ring is enclosed within an annular groove.
The sealing ring has elasticity.After the sealing ring banding splined shaft, the external diameter RF of sealing ring is more than splined shaft
Big footpath R.
The splined shaft is the output shaft of motor, and the output shaft coordinates with the spline housing of reducer input shaft.The sealing
Circle is located in spline housing.
Further, the electrodeposited chromium layers thickness is 0.03mm~0.042mm.
Further, the spline tooth height of the splined shaft is h, and the depth of annular groove is H, H=2h.
Further, the sealing ring is viton seal ring.
It is of the present utility model to have the technical effect that unquestionable, the electrodeposited coating of crome metal is covered with splined shaft, improve
The hardness of splined shaft, surface flatness, inoxidizability and wearability.Annular groove and close with what it coordinated is provided with splined shaft
Seal, improves the sealing between splined shaft and spline housing, so as to effectively prevent the leakage of spline housing lubricating grease, so as to subtract
Lack the abrasion of splined shaft and spline housing, extend the service life of splined shaft.
Brief description of the drawings
The stereogram of the splined shaft that Fig. 1 is provided for the utility model embodiment；
Fig. 2 is the sectional view at the annular groove of splined shaft (without sealing ring)；
Fig. 3 is the sectional view (band sealing ring) at the annular groove of splined shaft.
In figure：1st, splined shaft, 2, the electrodeposited coating of crome metal, 3, annular groove, 4, sealing ring.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples, but should not be construed the utility model
Above-mentioned subject area is only limitted to following embodiments.In the case where the above-mentioned technological thought of the utility model is not departed from, according to ability
Domain ordinary technical knowledge and customary means, make various replacements and change, all should be included in protection domain of the present utility model.
A kind of splined shaft of chromium plating for motor in electric automobile with sealing ring, including splined shaft 1 and electrodeposited chromium layers 2, with
